為了便於說明，以下對通過成型機將作為金屬板材的金屬材料成型並切斷來製造拉鍊用拉頭的停止鉤部件的一個非限定示例進行說明。金屬材料是長條狀，從未圖示的捲筒向下游側送出。金屬材料具有展性及延性，通過設置在捲筒的下游側的成型機的成型，沿著心軸的外周面彎曲。金屬材料恢復原始形狀，但是保持彎曲的形狀。利用組裝在成型機或其他裝置中的切割器切斷金屬材料，來獲得金屬片。拉鍊用拉頭的停止鉤部件不限於圖示例的形狀，可以採用其他各種形狀。本領域技術人員可以按照所需的停止鉤部件的形狀，如所需那樣設計心軸的外周面及沖頭的沖壓面。For convenience of explanation, a non-limiting example of a stop hook member for manufacturing a slider for a slide fastener by forming and cutting a metal material as a metal plate by a molding machine will be described below. The metal material is long and is sent out from a roll (not shown) to the downstream side. The metal material has ductility and ductility, and is bent along the outer peripheral surface of the mandrel by molding by a molding machine provided on the downstream side of the roll. The metal material returns to its original shape, but retains its curved shape. The metal material is cut by a cutter assembled in a molding machine or other device to obtain a metal sheet. The stop hook member of the slider for a slide fastener is not limited to the shape illustrated in the figure, and various other shapes can be adopted. Those skilled in the art can design the outer peripheral surface of the mandrel and the punching surface of the punch according to the shape of the required stop hook member as required.
圖1是包括本發明的成型機92的系統99的概略圖。在上游側的沖壓機91中，將作為金屬平板的金屬材料80在其寬度方向兩側進行沖裁加工。在下游側的成型機92中，將作為金屬平板的金屬材料80成型並切斷。結果，作為金屬片製造出停止鉤部件70。停止鉤部件70可以通過任意的各種方法組裝到拉頭主體中。FIG. 1 is a schematic diagram of a system 99 including a molding machine 92 of the present invention. In the upstream side punching machine 91, a metal material 80 as a flat metal plate is punched on both sides in the width direction. In the downstream molding machine 92, the metal material 80, which is a flat metal plate, is molded and cut. As a result, the stop hook member 70 is manufactured as a metal sheet. The stop hook member 70 can be assembled into the slider body by any of various methods.
從捲筒（未圖示）送出的金屬材料80由沖壓機91進行剪切加工。沖壓機91使用一個以上的沖頭對金屬材料80進行沖裁。沖壓機91包括一個以上的沖模和一個以上的沖頭。沖模或沖頭被適當地賦予形狀，將金屬材料80剪切加工成所需的形狀。在包括圖示例的某些情況下，通過沖壓機91在金屬材料80的寬度方向兩側形成凹部。凹部可以在金屬材料80的寬度方向兩側以相同的方式設置。金屬材料80的寬度方向與金屬材料80的長度方向及厚度方向正交。金屬材料80的長度方向與金屬材料80從沖壓機91流向成型機92的方向一致。金屬材料80的厚度方向可以是與金屬材料80具有的一對平坦面正交的方向。The metal material 80 sent out from a roll (not shown) is sheared by a punch 91. The punch 91 uses one or more punches to punch the metal material 80. The punch 91 includes more than one die and more than one punch. The die or punch is appropriately shaped, and the metal material 80 is cut into a desired shape. In some cases including the illustrated example, a recess 91 is formed on both sides of the metal material 80 in the width direction by a punch 91. The recessed portions may be provided in the same manner on both sides in the width direction of the metal material 80. The width direction of the metal material 80 is orthogonal to the length direction and the thickness direction of the metal material 80. The longitudinal direction of the metal material 80 coincides with the direction in which the metal material 80 flows from the punch 91 to the forming machine 92. The thickness direction of the metal material 80 may be a direction orthogonal to a pair of flat surfaces that the metal material 80 has.
如圖1所示，從沖壓機91被供給到成型機92的金屬材料80由每個單位長度80U的型構件（pattern）相連而成。在單位長度80U內，金屬材料80包括上游側端部81、下游側端部82、上游側端部81與下游側端部82之間的窄幅部83、上游側端部81與窄幅部83之間的寬幅部84以及下游側端部82與窄幅部83之間的寬幅部85。寬幅部84位於寬幅部85的上游側。如之前所述，即使只限於拉鍊用拉頭的停止鉤部件，從金屬材料80獲得的金屬片的形狀也存在各種例子。因此，本段的說明可以被理解為，以適合於製造作為某個非限定示例的停止鉤部件的方式，由沖壓機91對金屬材料80進行剪切加工。顯然，可以預期通過沖壓機91將金屬材料80剪切加工成其他形狀。另外，端部81、82與窄幅部83同樣，其寬度比寬幅部84、85窄。也能夠分別將上游側端部81及下游側端部82稱為第一及第二端部。也能夠分別將寬幅部84、85稱為第一及第二寬幅部。As shown in FIG. 1, the metal material 80 supplied from the punch 91 to the molding machine 92 is formed by a pattern of 80 U per unit length. Within a unit length of 80U, the metallic material 80 includes an upstream end portion 81, a downstream end portion 82, a narrow portion 83 between the upstream end portion 81 and the downstream end portion 82, an upstream end portion 81, and a narrow portion The wide portion 84 between 83 and the wide portion 85 between the downstream side end portion 82 and the narrow portion 83. The wide portion 84 is located upstream of the wide portion 85. As described above, there are various examples of the shape of the metal sheet obtained from the metal material 80 even if it is limited to the stop hook member of the slider for a slide fastener. Therefore, the description in this paragraph can be understood as the metal material 80 is sheared by the punch 91 in a manner suitable for manufacturing a stop hook member as a certain non-limiting example. Obviously, it is expected that the metal material 80 is cut into other shapes by the punch 91. In addition, the end portions 81 and 82 are narrower than the wide portions 84 and 85 in the same manner as the narrow portions 83. The upstream-side end portion 81 and the downstream-side end portion 82 may be referred to as first and second end portions, respectively. The wide portions 84 and 85 may be referred to as first and second wide portions, respectively.
通過在後文中詳細說明的成型機92進行的成型及切斷，從金屬材料80連續地排出金屬片，即圖示例中的停止鉤部件70。另外，由成型機92將本次的單位長度80U的部分成型時包含在該單位長度80U的部分內的端部82，是通過在由成型機92將上一次的單位長度80U的部分成型的過程中切斷金屬材料80而產生的自由端部。在由成型機92開始將本次的單位長度80U的部分成型時，包含在該單位長度80U內的端部81與一個上游側的單位長度80U的端部82連結。在本次成型時，成型機92將該連結的端部81與端部82切斷，由此端部81、82成為自由端部。同時，由成型機92從金屬材料80切出與作為本次成型物件的單位長度80U的部分相對應或與其相同的金屬片。也可以設想利用與成型機92不同的裝置來切斷金屬材80的另一示例。The metal sheet 80 is continuously discharged from the metal material 80 by the molding and cutting performed by the molding machine 92 described later in detail, that is, the stop hook member 70 in the illustrated example. In addition, when the 80U unit length portion is molded by the molding machine 92 this time, the end portion 82 included in the 80U unit length portion is formed by molding the previous 80U unit length portion by the molding machine 92. The free end portion produced by cutting the metal material 80 in the middle. When the molding unit 92 starts to form a portion of unit length 80U this time, the end portion 81 included in the unit length 80U is connected to one upstream portion 80U of the unit length 80U. In this molding, the molding machine 92 cuts the connected end portion 81 and the end portion 82 so that the end portions 81 and 82 become free end portions. At the same time, a metal sheet corresponding to or the same as a part of the unit length 80U which is the current molding object is cut out from the metal material 80 by the molding machine 92. It is also conceivable to use another device different from the forming machine 92 to cut the metal material 80.
圖2是由成型機92成型的作為金屬片的一個示例的停止鉤部件70的概略側視圖。圖3是由成型機92進行成型的過程中作為非限定半成品的停止鉤部件70的概略立體圖。從圖2及圖3可知，通過由成型機92進行的成型，在端部81與寬幅部84之間形成末端彎曲部86，在端部82與寬幅部85之間形成末端彎曲部87，在窄幅部83形成U型彎曲部88。通過由成型機92進行的成型，在寬幅部85還形成弧狀彎曲部89m，在寬幅部84還形成弧狀彎曲部89n。從停止鉤部件70自身無法識別作為其母材的金屬材料80的輸送方向。但是，根據參照圖1所述的金屬材料80的輸送方向，末端彎曲部86位於末端彎曲部87的上游側。弧狀彎曲部89m位於弧狀彎曲部89n的下游側。端部81、82及窄幅部83的寬度比較狹窄，是為了容易在金屬材80形成彎曲部86、87、88。在包括圖示例的某些情況下，為了形成一個以上的彎曲部，金屬材料80可以具有一個以上的窄幅部。窄幅部的個數、位置、長度可以根據實施例而變更。FIG. 2 is a schematic side view of a stop hook member 70 as an example of a metal sheet molded by the molding machine 92. FIG. 3 is a schematic perspective view of a stop hook member 70 as an unrestricted semi-finished product during molding by the molding machine 92. As can be seen from FIGS. 2 and 3, by the molding by the molding machine 92, a terminal bent portion 86 is formed between the end portion 81 and the wide portion 84, and a terminal bent portion 87 is formed between the end portion 82 and the wide portion 85. A U-shaped bent portion 88 is formed in the narrow width portion 83. By the molding by the molding machine 92, an arc-shaped curved portion 89m is further formed in the wide portion 85, and an arc-shaped curved portion 89n is further formed in the wide portion 84. The direction in which the metal material 80 as the base material is conveyed cannot be recognized from the stop hook member 70 itself. However, according to the conveying direction of the metal material 80 described with reference to FIG. 1, the end bent portion 86 is located on the upstream side of the end bent portion 87. The curved arc portion 89m is located on the downstream side of the curved arc portion 89n. The widths of the end portions 81 and 82 and the narrow width portion 83 are relatively narrow in order to easily form the bent portions 86, 87, and 88 in the metal material 80. In some cases including the illustrated examples, in order to form more than one bent portion, the metal material 80 may have more than one narrow width portion. The number, position, and length of the narrow sections can be changed according to the embodiment.
圖4是表示通過成型機92如何將金屬材料80成型的概略步驟圖。在圖4（a）中，將金屬材料80的窄幅部83較少地彎曲，在窄幅部83形成彎曲較小的U型彎曲部88。此外，將寬幅部84較少地彎曲，在寬幅部84形成弧狀彎曲部89n。在圖4（b）中，在金屬材料80的寬幅部85形成弧狀彎曲部89m，並且在金屬材料80的端部82的附近形成末端彎曲部87。在圖4（c）中，在金屬材料80的單位長度80U的邊界切斷金屬材料80。在圖4（d）中，在本次成型時被切斷的金屬材料80的端部81附近形成末端彎曲部86。在圖4（e）中，使之前已形成的彎曲較小的U型彎曲部88的彎曲程度增加，結果形成彎曲較大的U型彎曲部88。另外，從成型機92排出停止鉤部件70時，停止鉤部件70因其彈性而從圖4（e）所示的形狀發生變形，弧狀彎曲部89m與弧狀彎曲部89n之間的間隔能夠增加。FIG. 4 is a schematic flowchart showing how the metal material 80 is molded by the molding machine 92. In FIG. 4 (a), the narrow portion 83 of the metal material 80 is bent less, and a narrow U-shaped bend portion 88 is formed in the narrow portion 83. Further, the wide portion 84 is bent less, and an arc-shaped bent portion 89 n is formed in the wide portion 84. In FIG. 4 (b), an arc-shaped bent portion 89 m is formed in the wide portion 85 of the metal material 80, and an end bent portion 87 is formed near the end portion 82 of the metal material 80. In FIG. 4 (c), the metal material 80 is cut at a boundary of the unit length 80U of the metal material 80. In FIG. 4 (d), a terminal bent portion 86 is formed in the vicinity of the end portion 81 of the metal material 80 that is cut at the time of molding. In FIG. 4 (e), the degree of bending of the U-shaped bent portion 88 that has been formed with a small curvature before is increased, and as a result, the U-shaped bent portion 88 with a large curvature is formed. In addition, when the stop hook member 70 is discharged from the molding machine 92, the stop hook member 70 is deformed from the shape shown in FIG. increase.
圖5是表示成型機92的概略結構的概略圖。成型機92包括心軸110、心軸支撐部120、沖頭130、切割器140、供給部件150、控制器170、以及驅動源174。在心軸110的外周配置有多個沖頭130、一個切割器140、以及金屬材料80的供給部件150。在某些情況下，成型機92的心軸110、沖頭130、切割器140是可動部件。在某些情況下，設置有個數為可動部件總數以下的多個驅動源174。省略設置在驅動源174與可動部件之間的動力傳遞機構的圖示。FIG. 5 is a schematic diagram showing a schematic configuration of the molding machine 92. The molding machine 92 includes a mandrel 110, a mandrel support portion 120, a punch 130, a cutter 140, a supply member 150, a controller 170, and a drive source 174. A plurality of punches 130, one cutter 140, and a supply member 150 of a metal material 80 are arranged on the outer periphery of the mandrel 110. In some cases, the mandrel 110, the punch 130, and the cutter 140 of the molding machine 92 are movable parts. In some cases, a plurality of drive sources 174 are provided which are equal to or less than the total number of movable parts. The illustration of the power transmission mechanism provided between the drive source 174 and the movable member is omitted.
心軸110具有沿著軸向延伸的一個以上的心軸突起30。在包括圖示例的某些情況下，心軸110是柱狀部件，例如是金屬製的柱狀部件。心軸突起30延伸的軸向可以與心軸110的長度方向一致。心軸110具有適合於通過心軸110與沖頭130的協同動作而在金屬材料80形成一個以上的彎曲部的外周面。The mandrel 110 includes one or more mandrel protrusions 30 extending in the axial direction. In some cases including the illustrated example, the mandrel 110 is a columnar member, such as a metal columnar member. The axial direction in which the mandrel protrusion 30 extends may coincide with the longitudinal direction of the mandrel 110. The mandrel 110 has an outer peripheral surface suitable for forming one or more bent portions in the metal material 80 by the cooperative operation of the mandrel 110 and the punch 130.
心軸支撐部120具有沿著軸向延伸的空間，支撐被***或配置在空間內的心軸110。心軸支撐部120例如是金屬製的筒狀部件。在某些情況下，從心軸110的軸向觀察，劃定心軸支撐部120的空間的內周面輪廓與心軸110的外周面輪廓相似。劃定心軸支撐部120的空間的內周面輪廓，為了容許心軸110的軸向移動而比心軸110的外周面輪廓稍大。The mandrel support portion 120 has a space extending in the axial direction, and supports the mandrel 110 inserted or arranged in the space. The mandrel support portion 120 is, for example, a metal cylindrical member. In some cases, when viewed from the axial direction of the mandrel 110, the inner peripheral surface contour of the space delimiting the mandrel support portion 120 is similar to the outer peripheral surface contour of the mandrel 110. The inner peripheral surface contour of the space defining the mandrel support portion 120 is slightly larger than the outer peripheral surface contour of the mandrel 110 in order to allow the axial movement of the mandrel 110.
心軸110能夠以從心軸支撐部120突出的方式進行定位。在某些情況下，心軸110能夠相對於心軸支撐部120相對地移動。代替性或追加性地，心軸支撐部120能夠相對於心軸110相對地移動。The mandrel 110 can be positioned so as to protrude from the mandrel support portion 120. In some cases, the mandrel 110 can be relatively moved relative to the mandrel support portion 120. Instead or in addition, the mandrel support portion 120 can be relatively moved with respect to the mandrel 110.
沖頭130設置在心軸110的外周，與心軸110的外周面協同地在金屬材料80形成一個以上的彎曲部。沖頭130朝向心軸110移動，按壓配置在心軸110的外周面上的金屬材料80。通過在沖頭130與心軸110之間壓迫金屬材料80，將金屬材料80成型為與心軸110的外周面及/或沖頭130的沖壓面相對應的形狀。其結果，在金屬材料80形成一個以上的彎曲部。彎曲部可以是以除了180度以外的任意角度彎曲的部分。彎曲部可以包括V型、U型、C型、低矮的脊型、陡峭的脊型等各種彎曲形狀。在包括圖示例的某些情況下，沖頭130的沖壓面可以是心軸110側的沖頭130的端面，即與心軸110相對的面。The punch 130 is provided on the outer periphery of the mandrel 110 and forms one or more bent portions in the metal material 80 in cooperation with the outer peripheral surface of the mandrel 110. The punch 130 moves toward the mandrel 110 and presses the metal material 80 disposed on the outer peripheral surface of the mandrel 110. By pressing the metal material 80 between the punch 130 and the mandrel 110, the metal material 80 is formed into a shape corresponding to the outer peripheral surface of the mandrel 110 and / or the punched surface of the punch 130. As a result, one or more bent portions are formed in the metal material 80. The bent portion may be a portion bent at an arbitrary angle other than 180 degrees. The curved portion may include various curved shapes such as a V-shape, a U-shape, a C-shape, a low ridge shape, and a steep ridge shape. In some cases including the illustrated example, the punching surface of the punch 130 may be an end surface of the punch 130 on the mandrel 110 side, that is, a surface opposite to the mandrel 110.
在包括圖示例的某些情況下，沖頭130一邊被引導筒160引導一邊朝向心軸110移動。沖頭130因從驅動源174例如電動機經由動力傳遞機構被供給的動力而相應地靠近心軸110或遠離心軸110。電動機可以是用脈衝信號控制的步進電動機。驅動源174不限於電動機，也可以是發動機等其他驅動源。動力傳遞機構可以是將由驅動源174生成的旋轉力轉換成沖頭的直線運動的任意機構。動力傳遞機構例如可以包括小齒輪和齒條的組合、曲柄機構或任意的其他機構。將沖頭130最靠近心軸110的位置稱為加工位置，沖頭130最遠離心軸110的位置稱為退避位置。In some cases including the illustrated example, the punch 130 is moved toward the mandrel 110 while being guided by the guide cylinder 160. The punch 130 is moved closer to or farther from the mandrel 110 due to the power supplied from the drive source 174 such as a motor via the power transmission mechanism. The motor may be a stepping motor controlled by a pulse signal. The drive source 174 is not limited to an electric motor, and may be another drive source such as an engine. The power transmission mechanism may be any mechanism that converts the rotational force generated by the drive source 174 into linear motion of the punch. The power transmission mechanism may include, for example, a combination of a pinion and a rack, a crank mechanism, or any other mechanism. The position where the punch 130 is closest to the mandrel 110 is referred to as a processing position, and the position where the punch 130 is farthest from the mandrel 110 is referred to as a retreat position.
切割器140以切斷金屬材料80的方式動作。切割器140一邊被引導筒160引導，一邊因從驅動源174例如電動機經由動力傳遞機構被供給的動力而相應地在退避位置與切斷位置之間往復運動。與上述同樣，驅動源174及動力傳遞機構可以根據實施例採用各種形態。在切割器140位於切斷位置時，利用切割器140的刀尖146切斷金屬材料80。在某些情況下，切割器140如上述那樣在金屬材料80的單位長度80U的邊界切斷金屬材料80。The cutter 140 operates to cut the metal material 80. The cutter 140 is reciprocated between the retracted position and the cut-off position by the power supplied from the drive source 174 such as a motor via a power transmission mechanism while being guided by the guide cylinder 160. As in the above, the drive source 174 and the power transmission mechanism may take various forms depending on the embodiment. When the cutter 140 is located at the cutting position, the metal material 80 is cut by the cutting edge 146 of the cutter 140. In some cases, the cutter 140 cuts the metal material 80 at the boundary of the unit length 80U of the metal material 80 as described above.
在包括圖示例的某些情況下，切割器140構成為在切斷金屬材料80時推動心軸110上的金屬材料80的部分，即圖示例中的端部81。心軸110上的金屬材料80的部分，即圖示例中的端部81通過切割器140以使其遠離心軸110的方式移動。如圖示那樣，金屬材料80的端部81可以被切割器140推向上方。能夠提高金屬材料80的切斷的可靠性，並且也最適於金屬材料80的成型。In some cases including the illustrated example, the cutter 140 is configured to push a portion of the metallic material 80 on the mandrel 110 when the metallic material 80 is cut, that is, the end portion 81 in the illustrated example. The portion of the metal material 80 on the mandrel 110, that is, the end portion 81 in the illustrated example, is moved away from the mandrel 110 by the cutter 140. As shown, the end portion 81 of the metal material 80 can be pushed upward by the cutter 140. The cutting reliability of the metal material 80 can be improved, and it is also most suitable for forming the metal material 80.
控制器170執行使配置在心軸110外周的各沖頭130，也可以作為選項追加地使切割器140在適當的時刻移動的控制。例如，控制器170對驅動源174提供指令。驅動源174根據來自控制器170的指令生成規定量的動力。由驅動源174生成的動力經由動力傳遞機構被傳遞給沖頭130，使沖頭130移動。切割器140也同樣地因來自驅動源174的動力而相應地移動。The controller 170 executes control to move each of the punches 130 arranged on the outer periphery of the mandrel 110 or to move the cutter 140 at an appropriate timing as an option. For example, the controller 170 provides instructions to the drive source 174. The drive source 174 generates a predetermined amount of power in accordance with an instruction from the controller 170. The power generated by the drive source 174 is transmitted to the punch 130 via the power transmission mechanism, and the punch 130 is moved. Similarly, the cutter 140 is moved correspondingly by the power from the drive source 174.
各沖頭130基於控制器170的控制，在適當的時刻從退避位置移動到加工位置。此外，各沖頭130基於控制器170的控制，在適當的時刻從加工位置移動到退避位置。切割器140基於控制器170的控制，在適當的時刻從退避位置移動到切斷位置。切割器140基於控制器170的控制，在適當的時刻從切斷位置移動到退避位置。Each punch 130 moves from the retreat position to the processing position at an appropriate timing based on the control of the controller 170. In addition, each punch 130 moves from the processing position to the retreat position at an appropriate timing based on the control of the controller 170. The cutter 140 moves from the retreat position to the cutting position at an appropriate timing based on the control of the controller 170. The cutter 140 moves from the cutting position to the retracted position at an appropriate timing based on the control of the controller 170.
控制器170可以包括定序器。控制器170可以由硬體、軟體或它們的組合適當地構成。硬體可以包括CPU、記憶體、匯流排、I/O電路、介面電路、影像處理電路、圖像顯示裝置等。軟體可以包括能夠由CPU執行的一個以上的程式。The controller 170 may include a sequencer. The controller 170 may be appropriately configured by hardware, software, or a combination thereof. The hardware may include a CPU, a memory, a bus, an I / O circuit, an interface circuit, an image processing circuit, an image display device, and the like. Software can include more than one program that can be executed by a CPU.
供給部件150包括第一沖模151和第二沖模152。金屬材料80穿過第一沖模151與第二沖模152之間的間隙被供給到心軸110上。金屬材料80由未圖示的輸送單元、例如輥對輥輸送裝置從捲筒送出被輸送到下游側。The supply member 150 includes a first die 151 and a second die 152. The metal material 80 is supplied to the mandrel 110 through a gap between the first die 151 and the second die 152. The metal material 80 is conveyed from a roll to a downstream side by a conveyance unit (not shown) such as a roll-to-roll conveyance device.

Another example in which two or more mandrels are provided is also conceivable.

The mandrel 110 related to the present invention is divided into a plurality of mandrel members. In some cases including the illustrated example, the mandrel 110 is divided into a first mandrel member 10 and a second mandrel member 20. Another example of dividing the mandrel 110 into the first to third mandrel members is also conceivable.

The first mandrel member 10 and the second mandrel member 20 are provided in contact with each other. The mandrel protrusion 30 of the mandrel 110 is provided on at least one of the first and second mandrel members 10 and 20.

As a result, the durability of the mandrel protrusion 30 and / or the mandrel member provided with the mandrel protrusion 30 can be improved.

When the first mandrel member 10 receives an impact from the punch 130 via the metallic material 80, the first mandrel member 10 is supported by the second mandrel member 20. Compared with the case where the first mandrel member 10 and the second mandrel member 20 are integrally formed, the durability of the mandrel protrusion 30 and / or the first mandrel member 10 can be further improved. When the second spindle member 20 receives an impact from the punch 130 via the metallic material 80, the second spindle member 20 is supported by the first spindle member 10. Compared with the case where the first mandrel member 10 and the second mandrel member 20 are integrally formed, the durability of the second mandrel member 20 can be further improved.

In some cases including the illustrated example, the first mandrel member 10 is disposed on the second mandrel member 20, or the second mandrel member 20 is disposed on the first mandrel member 10, as a result, the first mandrel member 10 and the second spindle member 20 are fitted to each other. As can be seen from FIG. 7, in some cases, the convex portion 20 j of the second spindle member 20 is fitted into the concave portion 10 j of the first spindle member 10. As can be seen from FIG. 7, in some cases, the first spindle member 10 is shorter in the axial direction than the second spindle member 20.
在如本發明這樣將心軸110分割成多個分割片的情況下，即使某個分割片，例如第一心軸部件10發生破損，也能夠原樣利用其他分割片，例如第二心軸部件20。能夠促進沒有設置心軸突起30的心軸110的分割片的長壽命化。When the mandrel 110 is divided into a plurality of divided pieces as in the present invention, even if a certain divided piece, for example, the first mandrel member 10 is damaged, other divided pieces, such as the second mandrel member 20, can be used as they are. . The long life of the divided piece of the mandrel 110 without the mandrel protrusion 30 can be promoted.
在某些情況下，第一心軸部件10和第二心軸部件20由相同的材料例如金屬構成。在另一種情況下，第一心軸部件10和第二心軸部件20由不同的材料，例如不同的金屬構成。In some cases, the first mandrel member 10 and the second mandrel member 20 are composed of the same material, such as metal. In another case, the first mandrel member 10 and the second mandrel member 20 are made of different materials, such as different metals.
以下，參照圖8至圖17對成型機92的作為一個非限定示例的動作進行說明。圖8是表示成型機92的動作的示意圖，示意性地示出通過心軸110與第一沖頭131的協同動作來形成彎曲較小的U型彎曲部88及弧狀彎曲部89n。圖9是表示通過成型機92的圖8的動作而在金屬材料80形成彎曲較小的U型彎曲部88的概略圖。Hereinafter, the operation of the molding machine 92 as a non-limiting example will be described with reference to FIGS. 8 to 17. FIG. 8 is a schematic diagram showing the operation of the molding machine 92, and schematically illustrates the formation of a U-shaped curved portion 88 and an arc-shaped curved portion 89n with small curvatures through the cooperative operation of the mandrel 110 and the first punch 131. FIG. 9 is a schematic view showing a U-shaped bent portion 88 having a small curvature formed on the metallic material 80 by the operation of the forming machine 92 of FIG. 8.
從圖8及圖9可知，金屬材料80穿過供給部件150的第一沖模151與第二沖模152之間的間隙，將金屬材料80供給到心軸110上。金屬材料80被供給到從心軸支撐部120的端面120s突出的心軸110的端部上。被供給到心軸110上的金屬材料80在被第一沖頭131按壓之前，在心軸110上平坦地呈直線狀地配置。第一沖頭131因來自由控制器170控制的驅動源174的動力而相應地朝向心軸110移動。在第一沖頭131到達加工位置時，金屬材料80在第一沖頭131與心軸110之間被加壓並被彎曲，在金屬材料80形成彎曲較小的U型彎曲部88。第一沖頭131的沖壓面被設置為在第一沖頭131位於加工位置時與心軸110的第一表面111及第三表面113相對。將金屬材料80彎曲直到金屬材料80的端部82與第二心軸部件20接觸為止。在金屬材料80被供給到心軸110上時，心軸110自心軸支撐部120的端面120s起突出了長度L1。第二至第四沖頭132～134及切割器140位於退避位置。As can be seen from FIGS. 8 and 9, the metal material 80 passes through the gap between the first die 151 and the second die 152 of the supply member 150 to supply the metal material 80 to the mandrel 110. The metal material 80 is supplied to the end portion of the mandrel 110 protruding from the end surface 120 s of the mandrel support portion 120. The metal material 80 supplied to the mandrel 110 is arranged flat and linear on the mandrel 110 before being pressed by the first punch 131. The first punch 131 is moved toward the mandrel 110 accordingly by the power from the drive source 174 controlled by the controller 170. When the first punch 131 reaches the processing position, the metal material 80 is pressurized and bent between the first punch 131 and the mandrel 110, and a U-shaped bent portion 88 having a small curvature is formed in the metal material 80. The punching surface of the first punch 131 is disposed to face the first surface 111 and the third surface 113 of the mandrel 110 when the first punch 131 is located at the processing position. The metal material 80 is bent until the end portion 82 of the metal material 80 is in contact with the second spindle member 20. When the metal material 80 is supplied to the mandrel 110, the mandrel 110 protrudes from the end surface 120s of the mandrel support portion 120 by a length L1. The second to fourth punches 132 to 134 and the cutter 140 are located in a retracted position.
圖10是表示成型機92的動作的示意圖，示意性地示出通過心軸110與第一及第二沖頭131、132的協同動作來形成弧狀彎曲部89m及末端彎曲部87。圖11是表示通過成型機92的圖10的動作而在金屬材料80形成弧狀彎曲部89m及末端彎曲部87的概略圖。繼第一沖頭131之後，第二沖頭132因來自由控制器170控制的驅動源174的動力而相應地朝向心軸110移動。在第二沖頭132到達加工位置時，金屬材料80在第二沖頭132與心軸110之間被加壓並被彎曲，在金屬材料80形成弧狀彎曲部89m及末端彎曲部87。第二沖頭132的沖壓面被設置為在第二沖頭132位於加工位置時與心軸110的第二表面112相對。FIG. 10 is a schematic diagram showing the operation of the molding machine 92, and schematically illustrates the formation of an arc-shaped bent portion 89m and a tip bent portion 87 by the cooperative operation of the mandrel 110 and the first and second punches 131 and 132. FIG. 11 is a schematic view showing an arc-shaped bent portion 89 m and a terminal bent portion 87 formed on the metal material 80 by the operation of the molding machine 92 of FIG. 10. Following the first punch 131, the second punch 132 moves toward the mandrel 110 accordingly due to the power from the drive source 174 controlled by the controller 170. When the second punch 132 reaches the processing position, the metal material 80 is pressurized and bent between the second punch 132 and the mandrel 110, and an arc-shaped bent portion 89m and a tip bent portion 87 are formed in the metal material 80. The punching surface of the second punch 132 is disposed to be opposed to the second surface 112 of the mandrel 110 when the second punch 132 is in the processing position.
圖12是表示成型機92的動作的示意圖，示意性地示出通過切割器140的動作來切斷金屬材料80。圖13是表示通過成型機92的圖12的動作來切斷金屬材料的概略圖。繼第二沖頭132之後，切割器140因來自由控制器170控制的驅動源174的動力而相應地沿鉛直方向及/或向上方移動。在切割器140到達切斷位置時，通過切割器140在相鄰的單位長度80U的邊界切斷金屬材料80。金屬材料80的位於切斷位置的下游側的部分因切割器140而從心軸110稍稍向上方位移。切割器140在切斷金屬材料80之後返回到退避位置。此外，第二沖頭132也返回到退避位置。FIG. 12 is a schematic diagram showing the operation of the molding machine 92, and schematically illustrates the cutting of the metal material 80 by the operation of the cutter 140. FIG. 13 is a schematic view showing cutting of a metal material by the operation of FIG. 12 of the forming machine 92. FIG. Following the second punch 132, the cutter 140 is moved in the vertical direction and / or upward by the power from the drive source 174 controlled by the controller 170. When the cutter 140 reaches the cutting position, the metal material 80 is cut by the cutter 140 at the boundary of the adjacent unit length 80U. The portion of the metal material 80 located on the downstream side of the cutting position is slightly displaced upward from the mandrel 110 by the cutter 140. The cutter 140 returns to the retracted position after cutting the metal material 80. In addition, the second punch 132 also returns to the retracted position.
圖14是表示成型機92的動作的示意圖，示意性地示出通過心軸110與第一及第三沖頭131、133的協同動作來形成末端彎曲部86。圖15是表示通過成型機92的圖14的動作而在金屬材料80形成末端彎曲部86的概略圖。切割器140切斷金屬材料80之後，第三沖頭133因來自由控制器170控制的驅動源174的動力而相應地沿鉛直方向及/或向下方移動。在第三沖頭133到達加工位置時，金屬材料80在第三沖頭133與心軸110之間被加壓並被彎曲，在金屬材料80形成末端彎曲部86。第三沖頭133具有突起133f，在該突起133f與心軸110的第四表面114之間夾著金屬材料80（端部81）。第三沖頭133的沖壓面被設置為在第三沖頭133位於加工位置時與第四表面114相對。另外，金屬材料80的寬幅部84在第三沖頭133與心軸110之間被加壓並被彎曲，將寬幅部84的弧狀彎曲部89n進一步彎曲。FIG. 14 is a schematic diagram showing the operation of the molding machine 92, and schematically illustrates the formation of the distal end bent portion 86 by the coordinated operation of the mandrel 110 and the first and third punches 131 and 133. FIG. 15 is a schematic view showing the formation of the terminal bent portion 86 in the metal material 80 by the operation of the forming machine 92 in FIG. 14. After the cutter 140 cuts the metal material 80, the third punch 133 moves in the vertical direction and / or downwards due to the power from the drive source 174 controlled by the controller 170. When the third punch 133 reaches the processing position, the metal material 80 is pressurized and bent between the third punch 133 and the mandrel 110 to form a terminal bent portion 86 in the metal material 80. The third punch 133 has a protrusion 133f, and a metal material 80 (end portion 81) is sandwiched between the protrusion 133f and the fourth surface 114 of the mandrel 110. The punching surface of the third punch 133 is disposed to be opposed to the fourth surface 114 when the third punch 133 is located at the processing position. In addition, the wide portion 84 of the metal material 80 is pressurized and bent between the third punch 133 and the mandrel 110, and the arc-shaped bent portion 89n of the wide portion 84 is further bent.
切割器140切斷金屬材料80之後（在圖示例中，切割器140切斷金屬材料80，然後第三沖頭133對金屬材料80進行成型並彎曲之後），調節心軸110自心軸支撐部120突出的突出量。具體而言，執行心軸110相對於心軸支撐部120的移動及/或心軸支撐部120相對於心軸110的移動。在包括圖示例的某些情況下，機械連杆可以與位於被供給金屬材料80的心軸110端部（可以稱為第一端部）的相反側的心軸110端部（可以稱為第二端部）結合。機械連杆能夠因來自驅動源174的動力而相應地直線移動，其結果，心軸110產生軸向移動。After the cutter 140 cuts the metal material 80 (in the example shown in the figure, the cutter 140 cuts the metal material 80, and then the third punch 133 forms and bends the metal material 80), adjusts the mandrel 110 from the mandrel support The amount by which the portion 120 protrudes. Specifically, the movement of the mandrel 110 with respect to the mandrel support portion 120 and / or the movement of the mandrel support portion 120 with respect to the mandrel 110 is performed. In some cases including the illustrated example, the mechanical link may be opposite to the end of the mandrel 110 (which may be called Second end). The mechanical link can move linearly correspondingly by the power from the drive source 174, and as a result, the mandrel 110 moves axially.
從圖15和圖17的對比可知，心軸110從自心軸支撐部120的端面120s起突出了長度L1的狀態向自心軸支撐部120的端面120s起突出了長度L2的狀態轉變。與此相對應，心軸110上的金屬材料80（也可以稱為從金屬材料80切出的金屬片）移動到第一心軸部件10的心軸突起30上。可以設想用改變心軸110自心軸支撐部120起突出的突出量以外的方法將金屬材料80移動到第一心軸部件10的心軸突起30上的另一示例。As can be seen from the comparison between FIG. 15 and FIG. 17, the state in which the mandrel 110 protrudes from the end surface 120s of the mandrel support portion 120 by a length L1 is changed to the state in which the mandrel support portion 120 protrudes by a length L2. Corresponding to this, the metal material 80 (also referred to as a metal sheet cut out from the metal material 80) on the mandrel 110 is moved onto the mandrel protrusion 30 of the first mandrel member 10. Another example of moving the metal material 80 onto the mandrel protrusion 30 of the first mandrel member 10 by a method other than changing the protruding amount of the mandrel 110 from the mandrel support portion 120 is conceivable.
圖16是表示成型機92的動作的示意圖，示意性地示出通過心軸110與第一、第三及第四沖頭131、133、134的協同動作來形成彎曲較大的U型彎曲部88。圖17是表示通過成型機92的圖16的動作而在金屬材料80形成彎曲較大的U型彎曲部88的概略圖。繼第三沖頭133之後，第四沖頭134因來自由控制器170控制的驅動源174的動力而相應地朝向心軸110的心軸突起30移動。在第四沖頭134到達加工位置時，金屬材料80在第四沖頭134與心軸突起30之間被加壓並被彎曲，在金屬材料80形成彎曲較大的U型彎曲部88。第四沖頭134的沖壓面被設置為在第四沖頭134位於加工位置時與心軸突起30的第五表面35相對。FIG. 16 is a schematic diagram showing the operation of the molding machine 92, and schematically illustrates the formation of a U-shaped bent portion having a large bending by the coordinated operation of the mandrel 110 and the first, third, and fourth punches 131, 133, and 134. 88. FIG. 17 is a schematic view showing a U-shaped bent portion 88 having a large curvature formed on the metallic material 80 by the operation of the forming machine 92 of FIG. 16. Following the third punch 133, the fourth punch 134 is moved toward the spindle protrusion 30 of the spindle 110 accordingly by the power from the drive source 174 controlled by the controller 170. When the fourth punch 134 reaches the processing position, the metal material 80 is pressurized and bent between the fourth punch 134 and the mandrel protrusion 30, and a U-shaped bent portion 88 having a large curvature is formed in the metal material 80. The punching surface of the fourth punch 134 is disposed to be opposed to the fifth surface 35 of the spindle projection 30 when the fourth punch 134 is in the processing position.
在包括圖示例的某些情況下，接著，心軸110及/或心軸支撐部120以使心軸110的心軸突起30不從心軸支撐部120的端面120s突出的方式移動。由此，從心軸110放開停止鉤部件70，使其經由或不經由未圖示的排出路徑被供給到保管箱或袋中。In some cases including the illustrated example, the mandrel 110 and / or the mandrel support portion 120 are moved so that the mandrel protrusion 30 of the mandrel 110 does not protrude from the end surface 120s of the mandrel support portion 120. As a result, the stop hook member 70 is released from the mandrel 110 and is supplied to a storage box or a bag with or without a discharge path (not shown).
在包括圖示例的某些情況下，通過心軸突起30與沖頭130協同動作，在由切割器140切斷的金屬材料80的端部81、82形成末端彎曲部86、87。心軸突起30的大小變大，能夠提高心軸突起30的耐久性。In some cases including the illustrated example, the mandrel protrusion 30 cooperates with the punch 130 to form the end bent portions 86 and 87 at the end portions 81 and 82 of the metal material 80 cut by the cutter 140. The size of the mandrel protrusion 30 is increased, and the durability of the mandrel protrusion 30 can be improved.
在包括圖示例的某些情況下，在第一心軸部件10設置有心軸突起30，通過一個以上的沖頭130與第二心軸部件20的協同動作，在靠近為了從金屬材料80切出金屬片（成型機92的上一次的成型過程中）而由切割器140切斷的金屬材料80的端部82，於金屬材料80的部分形成至少一個彎曲部（弧狀彎曲部89m）。In some cases including the illustrated example, the first mandrel member 10 is provided with a mandrel protrusion 30, and is operated in cooperation with one or more punches 130 and the second mandrel member 20. The end portion 82 of the metal material 80 that was cut out by the cutter 140 during the last molding process of the metal sheet (the molding machine 92) forms at least one curved portion (arc-shaped curved portion 89m) in the metal material 80 portion.
在包括圖示例的某些情況下，靠近金屬材料80的端部82的金屬材料80的部分彎曲部（弧狀彎曲部89m），是在為了切出包括該彎曲部89m的金屬片（成型機92的本次的成型過程中）而通過切割器140切斷金屬材料80之前形成的。在通過第二沖頭132將金屬材料80向心軸110的第二表面112一側按壓的過程中，可以將新的金屬材料80拉入到成型機92內。能夠避免或抑制從金屬材料80切出的金屬片的長度比設計長度短。In some cases including the illustrated example, the partial bending portion (arc-shaped bending portion 89m) of the metal material 80 near the end portion 82 of the metal material 80 is for cutting out a metal sheet (molding) including the bending portion 89m. During the current molding process of the machine 92) and before the metal material 80 is cut by the cutter 140. In the process of pressing the metal material 80 toward the second surface 112 side of the mandrel 110 through the second punch 132, a new metal material 80 may be pulled into the molding machine 92. The length of the metal sheet cut out from the metal material 80 can be prevented or suppressed from being shorter than the designed length.
在包括圖示例的某些情況下，第一及第二心軸部件10、20中的至少一方相對於心軸支撐部120是可動的。在包括圖示例的某些情況下，第一及第二心軸部件10、20通過嵌合而結合，第一及第二心軸部件10、20相對於心軸支撐部120可一起移動。In some cases including the illustrated example, at least one of the first and second mandrel members 10 and 20 is movable relative to the mandrel support portion 120. In some cases including the illustrated example, the first and second mandrel members 10 and 20 are coupled by fitting, and the first and second mandrel members 10 and 20 can move together with respect to the mandrel support portion 120.
