본 고안은 프레스 금형에서 벤딩 및 피어싱(pieroing)동시가공 장치에 관한 것으로, 특히 벤딩과 피어싱을 동시에 처리함으로서 작업공간 및 공정을 줄이고, 제품의 정밀도를 향상시킬수 있도록한 프레스 금형에서 벤딩 및 피어싱 동시가공 장치에 관한 것이다.The present invention relates to a simultaneous bending and piercing device in a press die, and in particular, simultaneous bending and piercing in a press die that reduces work space and process and improves product precision by simultaneously processing bending and piercing. Relates to a device.

종래의 경우, 피어싱이 가공된형상의 제품을 가공하기 위해서는 먼저 U벤딩을 가공한후 Z벤딩과 피어싱을 각각 다른 공정에서 가공함으로서 금형의 낭비가 크고, 작업공간 및 인원이 많이 필요할 뿐만 아니라 성형품의 정밀도가 저하되는등의 결점이 있었다.In the conventional case, the piercing In order to process shaped products, U-bending is performed first, and then Z-bending and piercing are processed in different processes, resulting in a large waste of mold, requiring a lot of work space and personnel, and deterioration in the accuracy of molded products. there was.

따라서 본 고안은 상기와 같은 종래의 결점을 해소시키기 위해서 U벤딩, Z벤딩 피어싱 공정을 동시에 처리함으로서 성형품의 품질향상을 꾀할수 있도록 안출된것으로, 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is devised to improve the quality of the molded article by simultaneously processing the U-bending, Z-bending piercing process to solve the above-mentioned conventional drawbacks, the configuration and effect will be described in detail by the accompanying drawings. Is as follows.

상홀더(1)에 펀치고정판(2), 펀치가이드(3), 받침블럭(4)이 장치되고, 하홀더 (5)에 벤딩다이(6), 피어싱다이(7), 패드(8)(8')가 장치된 프레스 금형장치에 있어서, 상홀더(1)에 펀치고정판(2)을 관통한 정지볼트(9)와 탄성부재(10)를 통해, 경사면(1 1a)을 갖는 벤딩펀치(11)를 장치하고, 피어싱펀치(12)를 벤딩펀치(11)에 관통되게 장착하는 한편 벤딩펀치(11)의 경사면(11a)에는 슬라이딩 가능케 캠펀치(13)을 재치시켜서 받침블럭(4)에 탄성부재(10')로 연결시켜 구성된 것으로 미설명부호 14는 재료, 15는 제품 10″는 탄성부재인 것이다.The upper holder 1 is provided with a punch fixing plate 2, a punch guide 3, and a support block 4, and the lower holder 5 has a bending die 6, a piercing die 7, and a pad 8 ( 8 '), a bending punch having an inclined surface 11a through a stop bolt 9 and an elastic member 10 which penetrate the punch fixing plate 2 through the upper holder 1 11), the piercing punch 12 is mounted through the bending punch 11, and the slidable cam punch 13 is placed on the inclined surface 11a of the bending punch 11 to the support block 4. The reference numeral 14 denotes a material and 15 denotes an elastic member by connecting to the elastic member 10 '.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

도면 제1도에 도시된 바와 같이 하홀더(5)에 장치된 벤딩다이(6), 피어싱다이 (7), 패드(8)(8')상부에 재료(14)를 재치시킨후 펀치고정판(2), 벤딩펀치 (11), 펀치가이드(3), 받침블럭(4)이 장치된 상홀더(1)를 프레스에 의해 하향 이동시킴에 따라, 받침블럭(4)이 벤딩다이(6)에 안내되면서, 벤딩펀치(11)가 탄성부재(10)의 탄성력에 의해 재료(14)를 눌러주게되어 패드(8)(8')는 탄성부재(10″)를 수축시키면서 하홀더 (5)에 밀착될때까지 하향 이동되므로 재료(14)는 U 벤딩을 성형하게되며, 이때, 계속적인 하향이동에 따라 펀치가이드(3)에 의해 벤딩펀치(11)의 경사면(11a)에 탄성부재 (10)의 탄력을 받으면서 재치되어 잇는 캠펀치(13)가 경사면(11a)을 따라 슬라이딩 이동되면서 U 벤딩된 재료(14)의 가장자리부위를 Z 벤딩 시킨다.As shown in FIG. 1, the material 14 is placed on the bending die 6, the piercing die 7, and the pads 8 and 8 'provided in the lower holder 5, and then the punch fixing plate ( 2) As the upper holder 1 equipped with the bending punch 11, the punch guide 3, and the support block 4 is moved downward by a press, the support block 4 moves to the bending die 6. While being guided, the bending punch 11 presses the material 14 by the elastic force of the elastic member 10, so that the pads 8 and 8 'are contracted to the lower holder 5 while contracting the elastic member 10 ". Since the material 14 is moved downward until it is in close contact with each other, the material 14 forms a U-bending, and in this case, the punch guide 3 causes the elastic member 10 to be inclined to the inclined surface 11a of the bending punch 11 by the punch guide 3. The cam punch 13, which is placed while receiving elasticity, slides along the inclined surface 11a to Z-bend the edge portion of the U-bended material 14.

여기서 상기와 같이 Z 벤딩이 완료되기 직전에 벤딩펀치(11)를 관통하여 상홀더(1)에 장착된 피어싱펀치(12)는 피어싱다이(7)에 재치된 재료(14)에 피어싱을 가공하여 즉, 벤딩과 피어싱을 동시에 처리하여 제품(15)의 가공을 완료하게 된다.Here, the piercing punch 12 mounted on the upper holder 1 through the bending punch 11 just before Z bending is completed as described above is processed by piercing the material 14 placed on the piercing die 7. That is, bending and piercing are simultaneously processed to complete the processing of the product 15.

한편, 제품(15) 가공이 완료된후 제품을 취출하기 위해 펀치고정판(2), 벤딩펀치(11), 펀치가이드(3), 받침블럭(4)이 장치된 상홀더(1)를 상향이동시키면서 피어싱펀치(12)가 피어싱다이(7)와 제품(15)으로 부터 이탈되고 캠펀치(13)는 펀치가이드 (3)의 상승에 따라 받침블럭(4)에 일측이 고정된 탄성부재(10)의 탄성력에 의해 벤딩펀치(11)의 정사면(11a)에 슬라이딩 되면서 원래 상태로 복귀되고, 패드(8)(8')는 탄성부재(10″)의 원래 상태로 되돌아가려는 힘, 즉 탄성력에 의해 상승되면서 제품(15)을 취출시키므로 제품의 벤딩 및 피어싱 가공과 취출동작을 완료하게 되는 것이다.Meanwhile, the upper holder 1 equipped with the punch fixing plate 2, the bending punch 11, the punch guide 3, and the support block 4 is moved upward to take out the product after the processing of the product 15 is completed. The elastic member 10 having the piercing punch 12 separated from the piercing die 7 and the product 15 and the cam punch 13 fixed to one side of the support block 4 as the punch guide 3 rises. It is returned to its original state by sliding on the regular face 11a of the bending punch 11 by the elastic force of the pad, and the pads 8 and 8 'are forced to return to the original state of the elastic member 10 " The product 15 is taken out while being raised, thereby completing the bending and piercing processing and taking out operation of the product.
