Description
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
〔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.

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
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
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
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
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
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
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
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
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
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
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
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
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
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
