The mold is sequentially cut by a chain tooth thickness to obtain each element blank, and then a forming shape is formed by forming a mountain shape on the element head by a forming punch and a forming die. Moreover, the formed sprocket obtained by the method is recovered one by one in a state of being scattered, and then subjected to grinding processing or electroplating processing, and then implanted onto the zipper tape, or sequentially inserted into the zipper tape in order to form the sprocket forming. on.
通常，對於拉鏈之金屬製鏈齒，若成形之鏈齒表面不平滑，則不僅觸感差，而且拉頭之開閉操作多數亦不順暢。因此，為了消除此類問題，本案申請人已提出並實施了如下方法：在一邊間歇地供給截面成形為大致Y字狀之金屬線材、一邊利用切割衝頭及切割模按一鏈齒厚度依次切斷而得到各個鏈齒坯料之方式的上述鏈齒成形方法中，在與利用切割模進行線材之切斷的同時，在沿著下一次切斷線之鏈齒頭部的周緣及鏈齒腿部之外側緣的雙方進行倒角(參照專利文獻1)。 In general, in the metal fastener element of the zipper, if the surface of the formed fastener element is not smooth, not only the touch feeling is poor, but also the opening and closing operation of the slider is not smooth. Therefore, in order to eliminate such problems, the applicant of the present application has proposed and implemented a method of intermittently supplying a metal wire having a substantially Y-shaped cross section while intermittently cutting a thickness of a chain by a cutting punch and a cutting die. In the above-described sprocket forming method in which the respective sprocket blanks are obtained, the rim and the sprocket leg of the sprocket head along the next cutting line are cut along with the wire by the cutting die. Both of the outer edges are chamfered (see Patent Document 1).
此外，專利文獻2中記載了在正反任一方向均可開閉之所謂雙向 拉鏈用金屬製鏈齒之成形裝置中使用的切割衝頭，包括設有安裝槽及與該安裝槽嵌合的、用於在鏈齒之上表面形成缺口的刀之主體。 Further, Patent Document 2 describes a so-called two-way that can be opened and closed in either of the positive and negative directions. A cutting punch used in a metal sprocket forming device for a zipper includes a main body having a mounting groove and a knives fitted to the mounting groove for forming a notch on the upper surface of the sprocket.

The ground is supported. In the present specification, in describing a continuous manufacturing apparatus of a fastener stringer, the direction of the arrow c shown in FIG. 1 is referred to as the front, and the direction of the arrow d is treated as the rear.
如圖3所示，成形模4組裝在切割模1之前端面。切割衝頭2與成形衝頭3組態在未圖示之作為本裝置(拉鏈用鏈齒之成形裝置)之一部分的台架之固定位置，其中，成形衝頭3被構成為可沿圖1所示之箭頭e、f方向往復移動。因此，切割模1及成形模4此組、與切割衝頭2及成形衝頭3此組為可相互相對移動地對置設置之構造。另外，在本說明書中，在說明拉鏈牙鏈帶之連續製造裝置時，將圖1所示之箭頭e方向作為下方，將箭頭f方向作為後方來處理。將與前後方向垂直之方向、且與上下方向垂直之方向作為寬度方向來處理。 As shown in Fig. 3, the forming die 4 is assembled to the front end face of the cutting die 1. The cutting punch 2 and the forming punch 3 are disposed at a fixed position of a gantry which is a part of the device (the sprocket forming device) (not shown), wherein the forming punch 3 is configured as shown in FIG. The arrows e and f shown in the figure reciprocate. Therefore, the set of the cutting die 1 and the forming die 4, and the set of the cutting punch 2 and the forming punch 3 are opposed to each other so as to be movable relative to each other. In the present specification, in describing the continuous manufacturing apparatus of the fastener stringer, the direction of the arrow e shown in FIG. 1 is referred to as the lower direction, and the direction of the arrow f is treated as the rear. The direction perpendicular to the front-rear direction and the direction perpendicular to the vertical direction are treated as the width direction.
另外，在此，將切割模1及成形模4圖示記載為不同構件，但未必必須為不同構件，亦可用一構件形成切割模1及成形模4。 Here, the cutting die 1 and the molding die 4 are illustrated as different members, but they are not necessarily required to be different members, and the cutting die 1 and the molding die 4 may be formed by one member.
如圖1、圖3所示，在切割模1形成有鏈齒成形用線材W之穿通槽。截面為大致Y字狀之鏈齒成形用線材W穿通該線材穿通槽，利用未圖示之線材供給機構按鏈齒E之厚度之量、以規定節距間歇地向圖中上方供給該線材W。並且，在該線材穿通槽之上端緣具有刀部5。 在將鏈齒成形用線材W切斷時，使切割模1之刀部5與該線材W之一側面抵接，後述之切割衝頭2之第一刀部6與該線材W之另一側面抵接。 As shown in FIG. 1 and FIG. 3, a through-groove of the wire for forming the element teeth W is formed in the cutting die 1. A wire W for forming a sprocket having a substantially Y-shaped cross section is passed through the wire feed groove, and the wire supply mechanism is intermittently supplied to the upper portion of the wire at a predetermined pitch by a wire supply mechanism (not shown) at a predetermined pitch. . Further, a knife portion 5 is provided at an end edge of the wire feedthrough groove. When the wire W for the element forming is cut, the blade portion 5 of the cutting die 1 is brought into contact with one side surface of the wire W, and the first blade portion 6 of the cutting punch 2 and the other side of the wire W, which will be described later, are abutted. Abut.
圖2為切割衝頭之詳細圖。如圖1、圖2所示，切割衝頭2包括主體10，該主體10在向前方突出之突出部的頂端具有與切割模1之刀部5協作而將鏈齒成形用線材W切斷之第一刀部6，在主體之與切割模1相對的面上延伸設置有相對於切割模1滑動之滑動部11，在滑動部11上具有在切割模之滑動方向上朝向前方突出的第二刀部7。亦即，該第二刀部7沿與該第一刀部6相同之方向延伸。第二刀部7用於在鏈齒成形用線材W之一部分形成凹部。此外，在主體10上藉由釺焊設有用於將切割衝頭2固定在未圖示之本裝置之台架上的固定構件12，在固定構件12上設有利用作為連結元件之螺栓而連結的連結用孔23。因此，藉由將螺栓連結至連結用孔23，從而將切割衝頭2固定至未圖示之台架上，相對於切割模1滑動自如地與切割模1之刀部5協作而將鏈齒成形用線材W切斷。 Figure 2 is a detailed view of the cutting punch. As shown in FIG. 1 and FIG. 2, the cutting punch 2 includes a main body 10 which has a tip end portion projecting toward the front portion, and has a cutter portion 5 for cutting the fastener element 1 to cut the element W for the element forming. The first blade portion 6 has a sliding portion 11 that slides with respect to the cutting die 1 on a surface of the main body opposite to the cutting die 1, and a second portion that protrudes forward in the sliding direction of the cutting die on the sliding portion 11. Knife part 7. That is, the second blade portion 7 extends in the same direction as the first blade portion 6. The second blade portion 7 is for forming a concave portion in one portion of the wire forming wire W. Further, a fixing member 12 for fixing the cutting punch 2 to a gantry of the device (not shown) is provided on the main body 10 by brazing, and the fixing member 12 is provided with a bolt as a connecting member. The connection hole 23 is used. Therefore, by attaching the bolt to the connection hole 23, the cutting punch 2 is fixed to a stand (not shown), and the cutter die 1 is slidably engaged with the blade portion 5 of the cutting die 1 to sprocket The forming wire W is cut.
第一刀部6具有上側及下側敞開之凹部，該凹部之內面作為第一刀面8。第一刀面8具有與成為鏈齒E頭部之部分一致的形狀。第二刀部7具有第二刀面9，該第二刀面9具有以使向鏈齒成形用線材W側突出之刀的長度自上向下變短之方式形成的平坦傾斜面。第二刀部7之向鏈齒成形用線材W側最突出的刀尖處於，相對於第一刀面8之下表面在上下方向上離開了相當於待切斷的一鏈齒厚度之整數倍長度的位置，在圖示例子中處於相對於第一刀面8之下表面在上下方向上離開了一鏈齒厚度的位置。在此，第一刀部6之形狀沿上下方向為相同形狀，第二刀部7沿左右方向為相同形狀，亦即，第一刀部6及第二刀部7都為簡單構造，可藉由研磨加工而容易成形，因此與專利文獻1之切割衝頭相比，能夠大幅度降低成形成本。 The first blade portion 6 has a recessed portion that is open on the upper side and the lower side, and the inner surface of the recessed portion serves as the first blade face 8. The first blade face 8 has a shape that coincides with a portion that becomes the head of the element E. The second blade portion 7 has a second blade surface 9 having a flat inclined surface formed such that the length of the blade protruding toward the sprocket forming wire W side is shortened from the top to the bottom. The most prominent cutting edge of the second blade portion 7 on the side of the sprocket forming wire W is located in the vertical direction with respect to the lower surface of the first blade face 8 and is equivalent to an integral multiple of the thickness of a chain tooth to be cut. The position of the length, in the illustrated example, is at a position away from the thickness of a fastener element in the up and down direction with respect to the lower surface of the first blade face 8. Here, the shape of the first blade portion 6 has the same shape in the up-and-down direction, and the second blade portion 7 has the same shape in the left-right direction, that is, the first blade portion 6 and the second blade portion 7 are both simple structures, and can be borrowed. Since the molding process is easy to form, the molding cost can be significantly reduced as compared with the cutting punch of Patent Document 1.
鏈齒E之形成山狀形狀用的成形衝頭3藉由固定設置在未圖示之 台架上的未圖示之衝頭保持架而安裝於切割衝頭2之前方。此外，為了穩定成形力，可以與成形衝頭3相鄰地安裝按壓鏈齒E之腿部41、41之加壓墊13。如圖7所示，在成形衝頭3之頂端之後方側的側面具有槽15。槽具有由朝向該頂端之底面延伸之平坦面構成的斜面。該槽15形成有後述之鏈齒的傾斜面43，此係為了防止嚙合凹部前方側之周緣變薄所必需的，亦即，藉由用具有槽15之成形衝頭3成形嚙合凹部，從而能夠將形成嚙合凹部前方側之壁的厚度加厚。 The forming punch 3 for forming a mountain shape of the fastener element E is fixedly disposed not shown A punch holder (not shown) on the gantry is attached to the front of the cutting punch 2. Further, in order to stabilize the forming force, the pressing pad 13 of the leg portions 41, 41 of the sprocket E may be attached adjacent to the forming punch 3. As shown in Fig. 7, the side surface on the square side after the tip end of the forming punch 3 has a groove 15. The groove has a slope formed by a flat surface extending toward the bottom surface of the top end. The groove 15 is formed with an inclined surface 43 of a fastener element, which will be described later, in order to prevent the peripheral edge of the front side of the engagement recess from being thinned, that is, by forming the engagement recess by the forming punch 3 having the groove 15, The thickness of the wall forming the front side of the engaging recess is increased.
以下，簡單說明利用實施例之拉鏈用鏈齒之成形裝置，由作為鏈齒成形用線材W之金屬線材成形鏈齒E的過程。 In the following, a process of forming the fastener elements E from the metal wire of the wire for forming the fastener element W by the molding device for the fastener element for fasteners of the embodiment will be briefly described.
首先，將切割模1及成形模4此組置放在箭頭c方向之前進端，且將成形衝頭3及加壓墊13置放在箭頭f方向之上升端，且向上方送出鏈齒成形用線材W，並使該線材W以相當於1鏈齒的厚度，自切割模1之與切割衝頭2相對的端面突出地固定。 First, the cutting die 1 and the forming die 4 are placed in the forward direction of the arrow c direction, and the forming punch 3 and the pressure pad 13 are placed at the rising end in the direction of the arrow f, and the element is formed upwardly. The wire W is used, and the wire W is fixedly protruded from the end surface of the cutting die 1 opposed to the cutting punch 2 with a thickness corresponding to one fastener element.
接著，使切割模1及成形模4此組向箭頭d方向移動。藉由該移動，切割模1相對於切割衝頭2滑動，同時切割衝頭2之第一刀部6與切割模1之刀部5協作，將鏈齒成形用線材W之上端部切斷為鏈齒坯料。 Next, the set of the cutting die 1 and the forming die 4 is moved in the direction of the arrow d. By this movement, the cutting die 1 slides with respect to the cutting punch 2, while the first blade portion 6 of the cutting punch 2 cooperates with the blade portion 5 of the cutting die 1, and the upper end portion of the wire for forming the fastener element is cut into Chain tooth blank.
在上述切割模1及成形模4此組向箭頭d方向之滑動的末期，鏈齒坯料被切割衝頭2之第一刀部6押送而在成形模4之端面上移動，被移送至該成形模4與成形衝頭3之間的形成山狀形狀之成形位置。該形成山狀形狀之成形位置利用成形衝頭3、加壓墊13及成形模4進行成形之成形部位，當鏈齒坯料佔據形成山狀形狀之成形位置時，成形衝頭3及加壓墊13向箭頭e方向下降，與成形模4協作地成形鏈齒之嚙合凸部及嚙合凹部，亦即，成形鏈齒之嚙合頭部。 At the end of the sliding of the cutting die 1 and the forming die 4 in the direction of the arrow d, the sprocket blank is escorted by the first blade portion 6 of the cutting punch 2 and moved on the end face of the forming die 4, and transferred to the forming. A forming position between the die 4 and the forming punch 3 forming a mountain shape. The forming position at which the mountain shape is formed is formed by the forming punch 3, the pressure pad 13 and the forming die 4, and the forming punch 3 and the pressure pad are formed when the element blank occupies a forming position in which a mountain shape is formed. 13 is lowered in the direction of the arrow e, and the engaging convex portion and the engaging concave portion of the sprocket are formed in cooperation with the forming die 4, that is, the engaging head of the sprocket is formed.
在切斷上述鏈齒坯料、並向形成山狀形狀之成形位置移送之行程的末期，利用切割衝頭2之第二刀部7，將鏈齒成形用線材W之切斷端之下方側的一鏈齒量之部分衝壓並成形，從而在鏈齒成形用線材W 之側面形成凹入部14。由於第二刀部7具有第二刀面9，該第二刀面9具有以使向鏈齒成形用線材W側突出之刀的長度自上向下變短之方式形成的平坦傾斜面，因此在鏈齒成形用線材W之凹入部14亦與第二刀面9相符地形成為平坦之傾斜面。 At the end of the stroke of cutting the sprocket blank and transferring it to the molding position where the mountain shape is formed, the second blade portion 7 of the cutting punch 2 is used to lower the cutting end of the wire forming wire W. A part of a chain of teeth is stamped and formed so that the wire for forming a chain tooth W The concave portion 14 is formed on the side surface. Since the second blade portion 7 has the second blade surface 9, the second blade surface 9 has a flat inclined surface formed such that the length of the blade protruding toward the sprocket forming wire W side is shortened from the top to the bottom. The concave portion 14 of the wire forming wire W is also formed to be a flat inclined surface in conformity with the second blade surface 9.
該凹入部14之形成為藉由上述切割模1及成形模4此組相對於成形衝頭3、加壓墊13及成形模4此組進行之相對運動而形成的，在上述凹入部14之成形完成後，上述兩組再次向相反方向相對運動，返回最初之狀態，使鏈齒成形用線材W自切割模1之端面突出相當於1鏈齒之厚度的長度地進行固定，重複上述動作。 The concave portion 14 is formed by the relative movement of the cutting die 1 and the forming die 4 relative to the set of the forming punch 3, the pressure pad 13 and the forming die 4, and the concave portion 14 is formed. After the completion of the forming, the two sets are moved in the opposite directions again, and are returned to the initial state, and the element W for forming the element teeth is fixed from the end surface of the cutting die 1 by the length corresponding to the thickness of the one element tooth, and the above operation is repeated.
由於突出相當於該厚度之長度，因此凹入部14之上緣被帶至與切割模1之端面對準的位置。 Since the protrusion corresponds to the length of the thickness, the upper edge of the recessed portion 14 is brought to a position aligned with the end surface of the cutting die 1.
如上述成形之鏈齒，被緊固衝頭17直接逐個地依次植入至拉鏈帶T上，形成拉鏈牙鏈帶S。 The fastener elements thus formed are sequentially inserted one by one by the fastening punch 17 onto the fastener tape T one by one to form a fastener stringer S.
圖4至圖6表示上述成形之鏈齒。如圖所示，鏈齒E包括：在一面上具有嚙合凹部45、在另一面上具有嚙合凸部44之嚙合頭部42，及自嚙合頭部42延伸之一對腿部41。 4 to 6 show the above-described formed sprocket. As shown, the sprocket E includes an engaging head portion 42 having an engaging recess 45 on one side, an engaging projection 44 on the other side, and a pair of legs 41 extending from the engaging head 42.
另外，在本說明書中，在說明鏈齒時，如圖4所示，將嚙合頭部作為前側、將腿部側作為後側來處理。此外，將形成有嚙合凹部45之一面作為表側、將形成有嚙合凸部之另一面作為背側、將與由此被賦予方向性之前後方向及表背方向垂直的方向作為寬度方向來處理。 Further, in the present specification, when the sprocket is described, as shown in FIG. 4, the meshing head is used as the front side and the leg side is used as the rear side. Further, one surface of the engagement concave portion 45 is formed as a front side, and the other surface on which the engagement convex portion is formed is referred to as a back side, and a direction perpendicular to the front and rear directions and the front and back directions to which the directivity is imparted is treated as a width direction.
在嚙合頭部42之形成有嚙合凹部45之面的前端形成有與第二刀面9相符地成形之平坦傾斜面43。 A flat inclined surface 43 which is formed in conformity with the second blade surface 9 is formed at the front end of the surface of the engaging head portion 42 where the engaging recess portion 45 is formed.
由於在嚙合頭部42之形成有嚙合凹部45之面的前端形成有傾斜面43，因此在操作拉頭時，嚙合凸部44之底面不會卡到形成有嚙合凹部45之面的前端緣，因此可維持良好之滑動性。而且，由於傾斜面43保留所需最小限度之量，因此可不發生毛刺等成形。 Since the inclined surface 43 is formed at the front end of the surface of the engaging head portion 42 where the engaging concave portion 45 is formed, when the slider is operated, the bottom surface of the engaging convex portion 44 does not get stuck to the front end edge of the surface on which the engaging concave portion 45 is formed. Therefore, good slidability can be maintained. Moreover, since the inclined surface 43 retains the minimum amount required, molding such as burrs does not occur.
如圖5所示，在嚙合凸部44之側面48中的腿部側形成有由朝向嚙合凸部之底面延伸之平坦面構成的斜面47。此係為了防止在鏈齒彼此卡合時，鏈齒旋轉而使鏈齒彼此之嚙合脫開。此外，較佳為在嚙合凹部45中之、與斜面47相對的位置，形成同樣由平坦面構成之斜面，從而具有進一步防止旋轉之效果。 As shown in Fig. 5, a slope 47 formed by a flat surface extending toward the bottom surface of the engaging convex portion is formed on the leg side in the side surface 48 of the engaging convex portion 44. In order to prevent the fastener elements from rotating when the fastener elements are engaged with each other, the fastener elements are disengaged from each other. Further, it is preferable to form a slope which is also formed by a flat surface at a position facing the inclined surface 47 in the engagement concave portion 45, thereby further preventing the rotation.
如圖6所示，傾斜面43之最長寬度W2設定為大於嚙合凸部44之底面的寬度W3、小於嚙合凹部45之寬度W1。若作成具有大於W1之寬度W2的傾斜面43，則會產生毛刺。此外，若W2不大於嚙合凸部44之底面的最大寬度W3，則進行拉頭操作時，嚙合凸部44之底面會卡到形成有嚙合凹部45之面的前端緣，滑動性變差。因此，藉由如上述設定傾斜面43之寬度，在成形中不會產生毛刺等，成形後之鏈齒具有順滑之表面。 As shown in FIG. 6, the longest width W2 of the inclined surface 43 is set to be larger than the width W3 of the bottom surface of the engaging convex portion 44 and smaller than the width W1 of the engaging concave portion 45. If an inclined surface 43 having a width W2 larger than W1 is formed, burrs are generated. Further, when W2 is not larger than the maximum width W3 of the bottom surface of the engaging convex portion 44, when the slider operation is performed, the bottom surface of the engaging convex portion 44 is caught on the front end edge of the surface on which the engaging concave portion 45 is formed, and the slidability is deteriorated. Therefore, by setting the width of the inclined surface 43 as described above, burrs or the like are not generated during molding, and the formed fastener has a smooth surface.
此外，嚙合頭部42之寬度包括具有與腿部41之寬度相同之寬度的第一寬度W5，及小於第一寬度W5且形成於比第一寬度W5靠前端側之第二寬度W6，第一寬度W5及第二寬度W6由具有另外角度之階差斜面46連接。 Further, the width of the engaging head portion 42 includes a first width W5 having the same width as the width of the leg portion 41, and a second width W6 smaller than the first width W5 and formed on the front end side of the first width W5, first The width W5 and the second width W6 are connected by a stepped slope 46 having another angle.
為了滿足W3<W2，需要極力減小W3地設計鏈齒。作為該方法，將決定W3寬度之嚙合凸部自身設計得較小。但由於無法將鏈齒整體設計得較小，因此以W6<W5之方式設計鏈齒。腿部為了確保鏈齒自身之安裝強度，需要具有規定之寬度W5。 In order to satisfy W3 < W2, it is necessary to minimize the W3 design sprocket. As this method, the engaging convex portion which determines the width of W3 is designed to be small. However, since the entire element of the element cannot be designed to be small, the element is designed in the manner of W6 < W5. In order to ensure the mounting strength of the fastener itself, the leg needs to have a predetermined width W5.
此外，作為鏈齒成形用線材，只要能形成拉鏈鏈齒即可，無特別限定。較佳為將金屬材料作為鏈齒成形用線材。 In addition, the wire for element molding is not particularly limited as long as it can form a fastener element. It is preferable to use a metal material as a wire for forming a fastener element.
藉由以上說明可知，根據本發明，採用由生產率優良之金屬線材成形鏈齒之方式，而且在切割衝頭設置用於在鏈齒之頭部之外側端緣形成平坦傾斜面的第二刀部，因此不需要如以往之鏈齒成形裝置所必需的高成本之放電加工，切割衝頭能夠全部藉由研磨加工成形，因 此能夠以較低廉之成本製作。而且，在成形的同時在鏈齒之頭部之外側端緣形成平坦的傾斜面，因此提高了鏈齒之觸感，在操作拉頭時，嚙合凸部之底面不會卡到形成有嚙合凹部之面的前端緣，因此可維持良好之滑動性，保障利用拉頭使拉鏈順暢地進行開閉操作。本發明提供一種具有形狀簡單、低成本之切割衝頭之鏈齒成形裝置及拉鏈用鏈齒。 As apparent from the above description, according to the present invention, a sprocket is formed by a metal wire having excellent productivity, and a second blade portion for forming a flat inclined surface at the outer end edge of the head of the sprocket is provided in the cutting punch. Therefore, the high-cost electric discharge machining required for the conventional element forming device is not required, and the cutting punch can be completely formed by grinding, because This can be made at a lower cost. Moreover, a flat inclined surface is formed on the outer side edge of the head of the sprocket while being formed, thereby improving the tactile sensation of the sprocket, and the bottom surface of the engaging convex portion is not caught to be formed with the engaging concave portion when the slider is operated. The front end edge of the surface can maintain good slidability, and the zipper can be smoothly opened and closed by the slider. The present invention provides a fastener element forming device having a simple and low-cost cutting punch and a fastener element for a slide fastener.
