Description

進行板材加工的加工裝置及加工方法Processing device and processing method for plate processing

本發明關於用以加工金屬板等板材的加工裝置及加工方法，特別是關於能夠進行金屬板的雙面衝壓加工與切割加工的加工裝置及加工方法。The present invention relates to a processing device and a processing method for processing metal plates and other plates, and in particular to a processing device and processing method capable of double-sided punching and cutting of metal plates.

應用於精密機器的金屬零件等的加工，為使用包含衝壓裝置及模具的加工裝置所進行的。此外，近年來，應用於精密機器的金屬零件的加工需要較高的精度。例如，應用於行動裝置等連接器用金屬端子，則會隨著行動裝置小型化的要求，使得連接器及其端子也需要小型化。如此，若加工對象物的工件小型化時，加工裝置則需非常高的加工精度。The processing of metal parts, etc. applied to precision machines is performed using a processing device including a press device and a die. In addition, in recent years, the processing of metal parts applied to precision machines requires high precision. For example, metal terminals used in connectors such as mobile devices will require miniaturization of connectors and their terminals in accordance with the requirements for miniaturization of mobile devices. As such, when the size of the workpiece of the object to be processed is reduced, the processing device requires very high processing accuracy.

過去，本案發明人曾提出針對能夠使裝置小型化、且具有高精度的衝壓裝置及模具的方案（請參照專利文獻1）。即便是此專利文獻1所記載的衝壓裝置為結構較簡單之所謂的C型衝壓裝置，亦為具有較高加工精度的衝壓裝置。In the past, the inventor of this case has proposed a press device and die with high precision that can reduce the size of the device (please refer to Patent Document 1). Even if the press device described in Patent Document 1 is a so-called C-type press device with a relatively simple structure, it is also a press device with high processing accuracy.

〔專利文獻1〕日本專利第5636572號公報。[Patent Document 1] Japanese Patent No. 5636572.

然而，近年來，大量生產有加工金屬薄板的金屬製元件，以用於智慧型手機等電子機器的微型連接器之端子、LSI等半導體設備之導線架等為數眾多的產品中。However, in recent years, metal components made of processed metal sheets have been mass-produced, which are used in the terminals of micro-connectors of electronic devices such as smartphones, and lead frames of semiconductor devices such as LSIs.

此種金屬零件，由於係透過加工裝置衝壓板狀金屬所製成，因此經衝壓後的金屬板之板厚面處，會存在因加工裝置的衝頭及模具所造成的下垂部分以及金屬組織破裂的破裂面。此外，隨著衝頭及模具彼此之間的間隙等種種條件下，在包含板厚面的破裂處有時會產生毛邊。This kind of metal parts are made by stamping sheet metal through a processing device. Therefore, there will be sagging parts and metal structure cracks caused by the punch and die of the processing device on the thick surface of the stamped metal plate. The fractured surface. In addition, under various conditions such as the gap between the punch and the die, burrs may be generated at the cracks including the thickness of the plate.

近年來，因電子機器的處理速度高速化，流經連接器等信號也隨之高速化及高頻化。在此種電子機器中，如果連接器等有毛邊，該毛邊便有成為天線、進而有產生高頻雜訊之虞。由於此種高頻雜訊是造成在電子機器發生操作錯誤的原因，故在近年，要求電子機器中的連接器等需無毛邊且平坦的表面粗糙度。In recent years, as the processing speed of electronic equipment has increased, the signals flowing through connectors have also increased in speed and frequency. In this type of electronic equipment, if the connector or the like has burrs, the burrs may become antennas and may generate high-frequency noise. Since such high-frequency noise is the cause of operation errors in electronic equipment, in recent years, connectors in electronic equipment are required to have flat surface roughness without burrs.

此外，作為切割板材的加工裝置，有被稱為剪切機（Shearing）的裝置。此種剪切機，是一種藉由上刃與下刃夾持板材，進而加以剪斷的裝置，該等刃具設有被稱之為剪切角的角度。在剪切機中，藉由設有此角度的上刃與下刃夾持板材，如同剪刀般地加以剪斷板材。In addition, as a processing device for cutting sheet materials, there is a device called a shearing machine (Shearing). This kind of shearing machine is a device that clamps the plate by the upper blade and the lower blade, and then cuts it. The blades are provided with an angle called a shear angle. In the shearing machine, the upper and lower blades with this angle clamp the plate, and cut the plate like scissors.

在藉由該剪切機剪斷板材的情況下，於剪斷面將產生破裂面及毛邊，並產生板材的翹曲或扭轉。這些雖能夠透過調整上刃與下刃的刃具間隙、或是重新檢討剪切角等而達到一定程度的減輕，然而卻無法完全解決該等問題的發生。In the case of cutting the plate by the shearing machine, cracked surfaces and burrs will be generated on the sheared surface, and warping or twisting of the plate will occur. Although these can be reduced to a certain extent by adjusting the gap between the upper blade and the lower blade, or reviewing the shear angle, etc., these problems cannot be completely resolved.

本發明的目的在於解決如上所記載的問題，提供一種可儘量減少經衝壓或切割後的板材的板厚面上產生破裂面，亦能防止產生毛邊的加工裝置及加工方法。The purpose of the present invention is to solve the problems described above, and provide a processing device and a processing method that can minimize the occurrence of cracks on the plate thickness surface of the sheet after punching or cutting, and also prevent the generation of burrs.

本發明的板材的加工裝置，是一種用於進行板材的衝壓加工的加工裝置，其特徵在於，具備：一對模具，其具有衝壓形狀的衝頭孔，能夠將該板材從正面及背面夾持；一對衝頭，其在該衝頭孔內進退自如，能夠將該板材從正面及背面按壓；擠壓衝頭，其與該一對衝頭分開設置；以及驅動裝置，其驅動該模具、該衝頭以及該擠壓衝頭；該驅動裝置透過驅動該模具，將該板材夾持在初始位置，相對於該模具，藉由一方的衝頭按壓該板材以形成衝壓部，該衝壓部為使板材從該初始位置沿板材之板厚方向，順向移動板厚的20%至70%，藉由另一方的衝頭按壓該衝壓部，使該衝壓部從該初始位置沿板材之板厚方向，逆向移動板厚的20%至70%，使該板材及該衝壓部從該初始位置移動，藉由該擠壓衝頭將衝壓部從該板材衝壓。The plate processing device of the present invention is a processing device for press processing of a plate, and is characterized by comprising: a pair of dies having punch holes in a punching shape and capable of clamping the plate from the front and back ; A pair of punches, which can move forward and backward freely in the punch hole, can press the plate from the front and back; extrusion punches, which are set separately from the pair of punches; and a driving device, which drives the die and the punch Head and the extrusion punch; the drive device clamps the plate in the initial position by driving the die, and presses the plate relative to the die to form a stamping part. The stamping part is used to make the plate From the initial position along the thickness direction of the sheet, move 20% to 70% of the sheet thickness in the forward direction, and press the punching part by the other punch, so that the punching part is along the thickness direction of the sheet from the initial position. Reversely move 20% to 70% of the plate thickness to move the plate and the stamping part from the initial position, and press the stamping part from the plate by the extrusion punch.

根據本發明的加工裝置，由於藉由一方的衝頭按壓板材，使板材從初始位置沿板材之板厚方向，順向移動該板厚的20%至70%，以形成衝壓部，因此能使作為衝壓部的板材的另一側產生下垂。此外，藉由另一方之衝頭按壓衝壓部，使衝壓部從初始位置沿板材之板厚方向，逆向移動該板厚的20%至70%，亦能使衝壓部的一側產生下垂。此外，能藉由與一對衝頭分開設置的擠壓衝頭從板材取下衝壓部。而當藉由另一方的衝頭按壓衝壓部時，可使一方的衝頭從驅動裝置釋放，從而防止衝頭互相干擾，或亦可藉由驅動裝置使一方的衝頭往逆向返回。According to the processing device of the present invention, because one punch presses the sheet material, the sheet material is moved from the initial position along the thickness direction of the sheet material by 20% to 70% of the sheet thickness in the forward direction to form a stamping part. Sagging occurs on the other side of the sheet material used as the stamping part. In addition, by pressing the punching part by the other punch, the punching part moves 20% to 70% of the plate thickness in the direction of the plate thickness from the initial position, which can also cause one side of the punching part to sag. In addition, the punching part can be removed from the plate by the extrusion punch provided separately from the pair of punches. When the punching part is pressed by the other punch, the one punch can be released from the driving device, thereby preventing the punches from interfering with each other, or the driving device can make the one punch return in the reverse direction.

此外，設一方的衝頭的上升量為板厚的20%至70%，同時設另一方的衝頭下降量為板厚的20%至70%，藉此可儘量減少衝壓部以及衝壓部經衝壓後之衝壓洞側面的產生破裂面。此外，在衝壓部及衝壓洞的正面及背面產生下垂，從而亦能防止產生毛邊。In addition, suppose the rise of one punch is 20% to 70% of the plate thickness, and the fall of the other punch is set to 20% to 70% of the plate thickness, thereby minimizing the amount of punching and punching Cracked surface on the side of the punch hole after punching. In addition, sagging occurs on the front and back of the punching part and punching hole, thereby preventing the generation of burrs.

此外，在本發明的加工裝置中，由於一方的衝頭沒有***至另一方的衝頭孔（模具），因此衝頭與模具不會干擾。此外，另一方的衝頭亦不會干擾一方的模具。因此，減少各個衝頭及各個模具的損傷，且能夠大幅提高一對衝頭須再重新研磨等維護壽命。而且，本發明的加工裝置可為像衝壓機般的裝置，亦可為將衝頭及模具作為模具零件的模具裝置。In addition, in the processing device of the present invention, since one punch is not inserted into the other punch hole (die), the punch and the die do not interfere. In addition, the punch on the other side will not interfere with the die on the other side. Therefore, the damage of each punch and each die is reduced, and the maintenance life of a pair of punches such as re-grinding can be greatly improved. Moreover, the processing device of the present invention may be a device like a punching machine, or a mold device using a punch and a mold as mold parts.

此外，在本發明的加工裝置中，在由該擠壓衝頭衝壓之前，亦可藉由該一方的衝頭使該衝壓部返回至該初始位置。透過該結構，在衝壓部保持於板材的狀態下，能使板材移動。In addition, in the processing device of the present invention, before punching by the extrusion punch, the punching portion may be returned to the initial position by the one punch. With this structure, the plate can be moved while the press part is held on the plate.

另外，在本發明的加工裝置中，該擠壓衝頭可進退自如地設置於第二衝頭孔，該第二衝頭孔設置於該一對模具之一方，在該一對模具的另一方，可形成有衝壓開口，該衝壓開口係面對該第二衝頭孔，且以較該衝壓部大的方式開口。或者，該擠壓衝頭進退自如地設置於第二衝頭孔，該第二衝頭孔設置於一對第二模具之一方，該一對第二模具跟該一對模具分開設置，在該第二模具之另一方，可形成有衝壓開口，該衝壓開口係面對該第二衝頭孔，且以較該衝壓部大的方式開口。如此，擠壓衝頭、第二衝頭孔以及衝壓開口可設置於一對模具，亦可設置於跟一對模具分開設置的第二模具。In addition, in the processing device of the present invention, the extrusion punch is movably provided in the second punch hole, the second punch hole is provided on one side of the pair of dies, and on the other side of the pair of dies. , A punching opening may be formed, and the punching opening faces the second punch hole and opens in a larger manner than the punching part.

下模件6透過下模6a固定在未圖示的衝壓裝置。在驅動裝置中，驅動上模件3、上衝頭2以及下衝頭5時，藉由如正時皮帶等同步裝置同步各自的運動。而針對驅動裝置的構造，可採用本案發明人所提出之專利文獻1的公報所記載的構造作為一例。The lower mold 6 is fixed to a punching device not shown through the lower mold 6a. In the driving device, when the upper die 3, the upper punch 2 and the lower punch 5 are driven, their respective movements are synchronized by a synchronization device such as a timing belt. Regarding the structure of the driving device, the structure described in Patent Document 1 proposed by the inventor of the present application can be used as an example.

在本實施例中，無論金屬板20的板厚，上衝頭2與上衝頭孔4之間的間隙均設為3.0μm。下衝頭5與下衝頭孔7之間的間隙亦為同樣的數值。一般而言，衝頭與衝頭孔之間的間隙通常設為金屬板20的板厚的5%左右，例如，若是0.08mm（80μm）的板厚之金屬板，間隙則設為4.0μm，然而，該情形因經切割後的板厚面處產生破裂面而不佳。此外，除非有另外說明，否則本案的間隙代表單側間隙。In this embodiment, regardless of the thickness of the metal plate 20, the gap between the upper punch 2 and the upper punch hole 4 is set to 3.0 μm. The gap between the lower punch 5 and the lower punch hole 7 also has the same value. Generally speaking, the gap between the punch and the punch hole is usually set to about 5% of the thickness of the metal plate 20. For example, if it is a metal plate with a thickness of 0.08 mm (80 μm), the gap is set to 4.0 μm. However, this situation is unfavorable because a cracked surface is generated at the thick surface of the cut plate. In addition, unless otherwise specified, the gap in this case represents a unilateral gap.

接著，說明關於利用本實施例的加工裝置1加工金屬板20時的加工方法。在本實施例中，以使用素材為彈簧用磷青銅且板厚為0.08mm的金屬板20為例並說明。Next, the processing method when processing the metal plate 20 by the processing apparatus 1 of this embodiment is demonstrated. In this embodiment, a metal plate 20 whose material is phosphor bronze for spring and whose plate thickness is 0.08 mm is used as an example and described.

本發明的加工方法具備：保持步驟，其藉由上模件3及下模件6保持金屬板20；第一局部衝壓步驟，其利用下衝頭5從金屬板20的下側進行局部衝壓至其厚度的一部分的位置；第二局部衝壓步驟，其利用上衝頭2從金屬板20的上側進行局部衝壓；推回步驟，其利用下衝頭5從金屬板20將經切割後的衝壓部21推回至衝壓洞22；以及擠壓步驟，其從金屬板20的衝壓洞22擠壓出衝壓部21。The processing method of the present invention includes: a holding step, which holds the metal plate 20 by the upper die 3 and the lower die 6, and the first partial punching step, which uses the lower punch 5 to perform partial punching from the lower side of the metal plate 20 to The position of a part of its thickness; the second partial punching step, which uses the upper punch 2 to perform partial punching from the upper side of the metal plate 20; the push-back step, which uses the lower punch 5 to remove the cut punch from the metal plate 20 21 is pushed back to the punching hole 22; and an extrusion step, which extrudes the punching part 21 from the punching hole 22 of the metal plate 20.

首先，在保持步驟中，如圖1（A）所示，透過未圖示的輸送裝置將金屬板輸送至上模件3及下模件6之間，然後，如圖1（B）所示，往下方推擠上模件3，從而在規定的壓力之下，藉由上模件3及下模件6夾持金屬板20。設金屬板20的此狀態的位置為初始位置。此時，金屬板20透過未圖示的輸送裝置，在每個步驟中，以一定間距進行精確地輸送。First, in the holding step, as shown in Fig. 1(A), the metal plate is conveyed between the upper mold 3 and the lower mold 6 through a conveying device not shown, and then, as shown in Fig. 1(B), The upper mold 3 is pushed downward, and the metal plate 20 is clamped by the upper mold 3 and the lower mold 6 under a predetermined pressure. The position of the metal plate 20 in this state is the initial position. At this time, the metal plate 20 passes through a conveying device not shown, and is conveyed accurately at a certain interval in each step.

接著，在第一局部衝壓步驟中，如圖2（A）所示，使下衝頭5上升金屬板20厚度的20%至70%，並將下衝頭5壓入至金屬板20中並形成衝壓部21。此時，上衝頭2以不抵接於因下衝頭5的上升而凸起的衝壓部21表面上的方式保持於上方位置。從此狀態，如圖2（B）所示，使下衝頭5往下方移動，結束第一局部衝壓步驟。Next, in the first partial punching step, as shown in FIG. 2(A), the lower punch 5 is raised by 20% to 70% of the thickness of the metal plate 20, and the lower punch 5 is pressed into the metal plate 20 and The punching part 21 is formed. At this time, the upper punch 2 is held at the upper position so as not to abut on the surface of the punched portion 21 raised by the ascent of the lower punch 5. From this state, as shown in Fig. 2(B), the lower punch 5 is moved downward to end the first partial punching step.

接著，在第二局部衝壓步驟中，如圖3（A）所示，使上衝頭2往下方移動，如圖3（B）所示，使上衝頭2下降金屬板20厚度的20%至70%，藉由上衝頭2將衝壓部21壓入至金屬板20中。此時，下衝頭5移動至較因上衝頭2的下降而下降的衝壓部21底面還下方的位置。Next, in the second partial stamping step, as shown in FIG. 3(A), the upper punch 2 is moved downward, and as shown in FIG. 3(B), the upper punch 2 is lowered by 20% of the thickness of the metal plate 20 To 70%, the punching part 21 is pressed into the metal plate 20 by the upper punch 2. At this time, the lower punch 5 moves to a position below the bottom surface of the punching portion 21 that is lowered due to the lowering of the upper punch 2.

接著，如圖3（C）所示，將上衝頭2往上方提起，結束第二局部衝壓步驟。此時，衝壓部21處於嵌合於衝壓洞22的狀態，保持在金屬板20上而不會從衝壓洞22落下的狀態。Next, as shown in Fig. 3(C), the upper punch 2 is lifted upward to end the second partial punching step. At this time, the punching part 21 is in a state of being fitted into the punching hole 22 and held on the metal plate 20 without falling from the punching hole 22.

接著，如圖4（A）所示，在推回步驟中，往上方推擠下衝頭5。如圖4（B）所示，進行該下衝頭5的推擠，直到衝壓部21進入至衝壓洞22且保持於衝壓洞22的位置（初始位置）為止。此時，可將衝壓部21的下邊配合下模件6上表面的高度，也可將衝壓部21的上邊配合上模件3下表面的高度。Next, as shown in Fig. 4(A), in the push-back step, the lower punch 5 is pushed upward. As shown in FIG. 4(B), the pushing of the lower punch 5 is performed until the punching portion 21 enters the punching hole 22 and is held at the position (initial position) of the punching hole 22. At this time, the lower edge of the stamping part 21 can be matched with the height of the upper surface of the lower mold 6, or the upper edge of the stamping part 21 can be matched with the height of the lower surface of the upper mold 3.

接著，如圖5（A）所示，在擠壓步驟中，使金屬板20移動至用於擠壓步驟的擠壓裝置8的規定位置，該金屬板20的狀態是已使衝壓部21嵌合至衝壓洞22。擠壓裝置8具備擠壓上衝頭9、擠壓衝頭10以及擠壓下衝頭12。擠壓上衝頭9及擠壓下衝頭12相當於本發明的一對第二模具。在擠壓上衝頭9設置有使擠壓衝頭10沿上下方向導引的擠壓衝頭孔11（第二衝頭孔）。此外，在擠壓下衝頭12設置有沿上下方向貫通並開口的衝壓開口13。Next, as shown in FIG. 5(A), in the pressing step, the metal plate 20 is moved to a predetermined position of the pressing device 8 used in the pressing step, and the state of the metal plate 20 is that the pressing portion 21 has been inserted. Close to the punching hole 22. The extrusion device 8 includes an extrusion upper punch 9, an extrusion punch 10, and an extrusion lower punch 12. The extrusion upper punch 9 and the extrusion lower punch 12 correspond to a pair of second dies of the present invention. The upper extrusion punch 9 is provided with an extrusion punch hole 11 (second punch hole) through which the extrusion punch 10 is guided upward and downward. In addition, the pressing lower punch 12 is provided with a punching opening 13 penetrating and opening in the vertical direction.

擠壓衝頭10形成為抵接面10a的面積小於衝壓部21的表面面積。另一方面，設置於擠壓下衝頭12的衝壓開口13，形成為大於衝壓部21的表面面積。該擠壓裝置8設置於上述加工裝置1的下游側，且與加工裝置1分開形成。The extrusion punch 10 is formed such that the area of the abutting surface 10 a is smaller than the surface area of the pressing portion 21. On the other hand, the punch opening 13 provided in the lower extrusion punch 12 is formed to be larger than the surface area of the punch 21. The extrusion device 8 is provided on the downstream side of the processing device 1 and is formed separately from the processing device 1.

在擠壓步驟中，如圖5（A）所示，使金屬板20移動至下游側之用於擠壓步驟的擠壓裝置8的規定位置，該金屬板20的狀態是已使衝壓部21嵌合至經擠壓步驟後的衝壓洞22，如圖5（B）所示，使擠壓上衝頭9下降，藉由擠壓上衝頭9與擠壓下衝頭12而將金屬板20保持在規定位置。In the pressing step, as shown in FIG. 5(A), the metal plate 20 is moved to a predetermined position of the pressing device 8 for the pressing step on the downstream side, and the state of the metal plate 20 is the pressing part 21 Fitted to the punching hole 22 after the pressing step, as shown in FIG. 5(B), the pressing upper punch 9 is lowered, and the metal plate is pressed by pressing the upper punch 9 and pressing the lower punch 12 20 remains in the specified position.

接著，如圖5（C）所示，使擠壓衝頭10下降，利用擠壓衝頭10，將嵌合於衝壓洞22的衝壓部21朝向衝壓開口13擠壓。然後，將擠壓衝頭10返回至上方，同時使擠壓上衝頭9上升，解除金屬板20的保持。Next, as shown in FIG. 5(C), the pressing punch 10 is lowered, and the pressing part 21 fitted in the punch hole 22 is pressed toward the punch opening 13 by the pressing punch 10. Then, while returning the pressing punch 10 to the upper side, the pressing upper punch 9 is raised, and the holding of the metal plate 20 is released.

藉由以上步驟形成有衝壓洞22的金屬板20，使衝壓洞22的側面成為如圖6（A）及圖6（B）所示的狀態。圖6（A）的照片，是從正面觀察由金屬板20所形成的連接器用端子30。圖6（B）的照片，是從背面看該端子30。Through the above steps, the metal plate 20 with the punched hole 22 is formed, so that the side surface of the punched hole 22 becomes the state shown in FIGS. 6(A) and 6(B). The photograph of FIG. 6(A) is a front view of the connector terminal 30 formed of the metal plate 20. The photograph of Fig. 6(B) shows the terminal 30 viewed from the back.

另外，在圖6（A）及圖6（B）中所揭示之端子30的側面31，並非藉由上述步驟加工，而是利用未圖示的側面加工用衝頭及側面加工用模具從圖6（A）的正面向單方向衝壓的結果的剖面。In addition, the side surface 31 of the terminal 30 disclosed in FIG. 6(A) and FIG. 6(B) is not processed by the above-mentioned steps, but by using a punch for side processing and a mold for side processing not shown 6(A) is a cross section of the result of pressing the front side in one direction.

如圖6（A）所示，觀察端子30的正面側，衝壓洞22的正面側的上緣部，為藉由上衝頭2的第二局部衝壓步驟所加工而呈現表面下垂22a。端子30的側面31的正面側的上緣部，亦為利用側面加工用衝頭所衝壓而呈現表面下垂31B。As shown in FIG. 6(A), observing the front side of the terminal 30, the upper edge portion of the front side of the punching hole 22 is processed by the second partial punching step of the upper punch 2 to show a surface sag 22a. The upper edge part of the front side of the side surface 31 of the terminal 30 is also punched by the punch for side surface processing, and the surface sag 31B appears.

另一方面，如圖6（B）所示，觀察端子30的背面側，衝壓洞22的背面側的下緣部，則為藉由下衝頭5的第一局部衝壓步驟所加工而呈現表面下垂22b。另一方面，端子30的側面31的背面側的下緣部，為利用側面加工用衝頭所衝壓的側面加工用模具之一側的表面，此處為破裂面。On the other hand, as shown in Fig. 6(B), observing the back side of the terminal 30, the lower edge of the punch hole 22 on the back side is processed by the first partial punching step of the lower punch 5 to present a surface Drooping 22b. On the other hand, the lower edge portion on the back side of the side surface 31 of the terminal 30 is the surface on one side of the side surface processing die punched by the side surface processing punch, and here is the fracture surface.

如此，利用本實施例的加工裝置1以及加工方法所加工的衝壓洞22，使正面側的上緣部及背面側的下緣部，均形成為表面下垂22a、22b。此外，在衝壓洞22的內周面，並無破裂面，且表面下垂22a、22b之間的部分形成為切割面22c。In this way, in the punch hole 22 processed by the processing device 1 and the processing method of this embodiment, the upper edge portion on the front side and the lower edge portion on the back side are both formed as surface sags 22a and 22b. In addition, there is no fracture surface on the inner peripheral surface of the punch hole 22, and the portion between the surface sag 22a and 22b is formed as a cut surface 22c.

因此，本實施例的加工裝置1以及加工方法應用於連接器用端子30的加工的情況時，藉由將對方側端子***至衝壓洞22，從而在與對方側端子接觸的表面不會產生破裂面，並能使連接器的連接狀態為良好。Therefore, when the processing device 1 and the processing method of the present embodiment are applied to the processing of the connector terminal 30, by inserting the counterpart terminal into the punch hole 22, the surface contacting the counterpart terminal will not be cracked. , And can make the connection status of the connector good.

此外，根據本實施例的加工裝置1以及加工方法，會抑制在加工處產生的毛邊。藉此，本實施例的加工裝置1以及加工方法應用於例如用於半導體的導線架的加工時，能提供無毛邊且可靠性較高的導線架。In addition, according to the processing device 1 and the processing method of the present embodiment, burrs generated at the processing place can be suppressed. Thereby, when the processing device 1 and the processing method of the present embodiment are applied to the processing of lead frames for semiconductors, for example, a lead frame with no burrs and high reliability can be provided.

而且，在上述實施例中，雖在第一局部衝壓步驟中使下衝頭5上升，並在第二局部衝壓步驟中使上衝頭2下降，反之，亦可在第一局部衝壓步驟中使上衝頭2下降，並在第二局部衝壓步驟中使下衝頭5上升。此時，在推回步驟中，使下衝頭5以不接觸於金屬板20的方式下降，同時使上衝頭2下降，從而將藉由第二局部衝壓步驟所產生的衝壓部21返回至衝壓洞22即可。Moreover, in the above-mentioned embodiment, although the lower punch 5 is raised in the first partial punching step, and the upper punch 2 is lowered in the second partial punching step, conversely, it can also be used in the first partial punching step. The upper punch 2 is lowered, and the lower punch 5 is raised in the second partial punching step. At this time, in the push-back step, the lower punch 5 is lowered so as not to contact the metal plate 20, and at the same time the upper punch 2 is lowered, thereby returning the punched portion 21 produced by the second partial punching step to Punch the hole 22.

此外，在上述實施例中，藉由驅動裝置使上模件3上下運動，且將下模件6固定於衝壓裝置，但不以此為限，亦可將上模件3固定於衝壓裝置，且藉由驅動裝置使下模件6上下運動。In addition, in the above embodiment, the upper mold 3 is moved up and down by the driving device, and the lower mold 6 is fixed to the punching device, but it is not limited to this, and the upper mold 3 may also be fixed to the punching device. And the lower mold 6 is moved up and down by the driving device.

此外，在上述實施例中，在第一局部衝壓步驟中，使下衝頭5上升金屬板20的板厚的20%至70%，該比例為隨金屬板20的材質或厚度來適當決定。針對在第二局部衝壓步驟中的上衝頭2亦為如此。In addition, in the above embodiment, in the first partial pressing step, the lower punch 5 is raised by 20% to 70% of the thickness of the metal plate 20, and the ratio is appropriately determined according to the material or thickness of the metal plate 20. The same is true for the upper punch 2 in the second partial punching step.

此外，在上述實施例中，擠壓裝置8由擠壓上衝頭9、擠壓衝頭10、以及擠壓下衝頭12所構成，但不以此為限，亦可將擠壓上衝頭9與上模件3形成為一體的結構。此時，可將下模件6與擠壓下衝頭12形成為一體的結構。In addition, in the above-mentioned embodiment, the extrusion device 8 is composed of an extrusion upper punch 9, an extrusion punch 10, and an extrusion lower punch 12. However, it is not limited to this, and the extrusion upper punch The head 9 and the upper mold 3 are formed as an integral structure. At this time, the lower die 6 and the extrusion lower punch 12 can be formed as an integral structure.

此外，在上述實施例中，作為板材，以金屬板20為例並說明，但不以此為限，亦可為其他素材的板材，如紙的板材、雲母板、合成樹脂板等。此外，本發明對板厚小於等於0.3mm的板材特別有效。此外，上衝頭孔4與上衝頭2之間隙以及下衝頭孔7與下衝頭5之間隙均設為3.0μm，然而介於1.5μm至3.0μm即可。In addition, in the above-mentioned embodiment, the metal plate 20 is taken as an example and illustrated as a plate, but it is not limited to this, and it can also be a plate of other materials, such as a paper plate, a mica plate, a synthetic resin plate, and the like. In addition, the present invention is particularly effective for plates with a plate thickness of 0.3 mm or less. In addition, the gap between the upper punch hole 4 and the upper punch 2 and the gap between the lower punch hole 7 and the lower punch 5 are all set to 3.0 μm, but only 1.5 μm to 3.0 μm.

接著，針對本發明中進行板材的切割加工的加工裝置及加工方法，參照圖7至圖8說明。作為進行金屬板20的切割加工的加工裝置之切割裝置1B，具備：一對第一刀具40，其能夠將金屬板20從正面及背面夾持；一對第二刀具50，以與該第一刀具40將切割預定線L夾於其中的方式設置刀具；以及驅動裝置60，其驅動第一刀具40及第二刀具50。Next, the processing device and processing method for cutting the plate material in the present invention will be described with reference to FIGS. 7 to 8. The cutting device 1B, which is a processing device for cutting the metal plate 20, is provided with a pair of first cutters 40 capable of clamping the metal plate 20 from the front and back sides, and a pair of second cutters 50 to interact with the first The cutter 40 is provided with the cutter in such a manner that the planned cutting line L is clamped therein; and the driving device 60 drives the first cutter 40 and the second cutter 50.

第一刀具40，下方為固定在設置位置的台座41、上方為透過驅動裝置60上下運動的板材壓制件42。第二刀具50，下方為下刃51、上方為上刃52。切割預定線L為表示金屬板20經切割後的邊緣的線（請參照圖8（B）），實際上為未在金屬板20的表面上出現的假想線。For the first cutter 40, the lower part is a pedestal 41 fixed at the set position, and the upper part is a plate pressing piece 42 that moves up and down through the driving device 60. The second cutter 50 has a lower blade 51 at the bottom and an upper blade 52 at the top. The planned cutting line L is a line indicating the edge of the metal plate 20 after being cut (refer to FIG. 8(B) ), and is actually an imaginary line that does not appear on the surface of the metal plate 20.

如圖7（A）所示，驅動裝置60具備第一驅動部61，其使板材壓制件42上下運動；第二驅動部62，其使下刃51上下運動；以及第三驅動部63，其使上刃52上下運動。在本案中例示性地表示該等驅動部，具體而言，作為此種切割裝置，由一般廣泛地應用的汽缸或凸輪機構等所構成。由該等所構成的驅動裝置60同步各個驅動部並驅動。而且，在圖7（B）至圖8中省略驅動裝置60的圖示。As shown in FIG. 7(A), the driving device 60 includes a first driving part 61 which moves the sheet material pressing 42 up and down; a second driving part 62 which moves the lower blade 51 up and down; and a third driving part 63 which The upper blade 52 is moved up and down. In this case, these driving parts are exemplarily shown. Specifically, as such a cutting device, it is constituted by a generally widely used cylinder or cam mechanism. The driving device 60 composed of these drives synchronizes the respective driving parts and drives. In addition, the illustration of the driving device 60 is omitted in FIGS. 7(B) to 8.

本實施例之切割裝置1B以第一刀具40及第二刀具50之間的間隙為從0至金屬板20厚度的5%左右的方式調整。該間隙依照金屬板20的厚度或素材適當地調整，使得於無產生毛邊等的方式切割金屬板20。The cutting device 1B of this embodiment is adjusted such that the gap between the first knife 40 and the second knife 50 is from 0 to about 5% of the thickness of the metal plate 20. The gap is appropriately adjusted in accordance with the thickness or material of the metal plate 20 so that the metal plate 20 is cut without burrs or the like.

接著，參照圖7來說明針對利用本實施例之切割裝置1B對金屬板20切割的方法。本實施例之切割方法（加工方法）由如下步驟所構成：初始位置保持步驟，其在初始位置藉由第一刀具40及第二刀具50將金屬板20保持；第一部分切割步驟，其使第一刀具40及第二刀具50往順向相對移動；第二部分切割步驟，其使第一刀具40及第二刀具50往逆向相對移動；以及返回步驟，其將第一刀具40及第二刀具50返回至初始位置。Next, a method for cutting the metal plate 20 with the cutting device 1B of this embodiment will be described with reference to FIG. 7. The cutting method (processing method) of this embodiment is composed of the following steps: an initial position holding step, which holds the metal plate 20 in the initial position by the first cutter 40 and the second cutter 50; the first partial cutting step, A cutter 40 and a second cutter 50 are relatively moved in the forward direction; the second partial cutting step is to move the first cutter 40 and the second cutter 50 to the opposite direction; and the return step is to move the first cutter 40 and the second cutter 50 returns to the initial position.

圖7（A）表示使金屬板20移動至第一刀具40之台41的表面上的狀態。此時，第一刀具40之板材壓制件42被保持在遠離台座41的上方，上刃52及下刃51亦被保持在遠離金屬板20的上下方之位置。FIG. 7(A) shows a state where the metal plate 20 is moved to the surface of the table 41 of the first cutter 40. At this time, the plate pressing part 42 of the first cutter 40 is kept away from the upper part of the base 41, and the upper blade 52 and the lower blade 51 are also kept away from the upper and lower positions of the metal plate 20.

接著，如圖7（B）所示，使第一刀具40之板材壓制件42下降，藉由板材壓制件42將金屬板20壓制至台座41上，從而保持金屬板20。此外，在第二刀具50中，亦使上刃52下降而與金屬板20抵接，且使下刃51上升而與金屬板20抵接。在本實施例中，以圖7（B）的該第一刀具40及第二刀具50的位置作為初始位置。Next, as shown in FIG. 7(B), the plate pressing member 42 of the first cutter 40 is lowered, and the metal plate 20 is pressed onto the base 41 by the plate pressing member 42 to hold the metal plate 20. In addition, in the second cutter 50, the upper blade 52 is also lowered to abut the metal plate 20, and the lower blade 51 is raised to abut the metal plate 20. In this embodiment, the positions of the first tool 40 and the second tool 50 in FIG. 7(B) are taken as initial positions.

接著，如圖7（C）所示，在保持作為第一刀具40的台座41及板材壓制件42的位置的狀態下，將作為第二刀具50的下刃51及上刃52往上方（板材的板厚方向的順向）按壓並推擠（第一部分切割步驟）。此時上升高度設為從初始位置至金屬板20板厚的20%至70%的高度。該比例因隨金屬板20的板厚及材質使得將俐落切割金屬板20的比例有所不同，因此配合實際的切割作業，算出適當的比例。Next, as shown in FIG. 7(C), while maintaining the positions of the base 41 as the first cutter 40 and the plate pressing member 42, move the lower blade 51 and the upper blade 52 as the second cutter 50 upward (the plate Press and push (the first part of the cutting step). At this time, the rising height is set to a height from the initial position to 20% to 70% of the thickness of the metal plate 20. Since this ratio varies with the thickness and material of the metal plate 20, the ratio of the metal plate 20 to be cut neatly is different. Therefore, an appropriate ratio is calculated according to the actual cutting operation.

接著，如圖8（A）所示，在保持作為第一刀具40的台座41及板材壓制件42的位置的狀態下，將作為第二刀具50的下刃51及上刃52往下方（板材的板厚方向的逆向）推擠（第二部分切割步驟）。此時下降高度亦設為從初始位置至金屬板20之板厚的20%至70%的高度。此時，圖7（C）的上升比例與圖8（A）的下降比例可設為相同比例，亦可設為彼此不同的比例。Next, as shown in FIG. 8(A), while maintaining the positions of the base 41 as the first cutter 40 and the plate pressing material 42, the lower blade 51 and the upper blade 52 as the second cutter 50 are moved downward (the plate The opposite direction of the plate thickness) push (the second part of the cutting step). At this time, the descending height is also set from the initial position to a height of 20% to 70% of the thickness of the metal plate 20. At this time, the rising ratio of FIG. 7(C) and the falling ratio of FIG. 8(A) may be the same ratio or may be different ratios.

接著，如圖8（B）所示，在保持作為第一刀具40的台座41及板材壓制件42的位置的狀態下，將作為第二刀具50的下刃51及上刃52返回至初始位置（返回步驟）。透過該等一系列的步驟，進行金屬板20的切割。Next, as shown in FIG. 8(B), the lower blade 51 and the upper blade 52 as the second blade 50 are returned to their initial positions while maintaining the positions of the pedestal 41 and the plate pressing member 42 as the first blade 40 (Return to step). Through these series of steps, the metal plate 20 is cut.
