본 고안은 프레스 벤딩 금형에 있어서 U자형 벤딩을 할 경우에 스프링 백양을 미리 예측하고 그 양만큼 더 벤딩시키므로써 외력을 제기 했을때 스프링 백이 발생하면 본래 원하는 직각도를 얻을수 있게된 프레스 벤딩 금형의 스프링 백 방지 장치에 관한 것이다.The present invention predicts the spring weight in case of U-shaped bending in press bending mold, and the spring of the press bending mold can obtain the original right angle when the spring back occurs when the external force is raised by bending the amount more. It relates to a bag prevention device.

종래의 프레스 벤딩 금형에 있어서는 U자형 벤딩을 할 경우에 스프링백이 발생하여 직각도를 유지시키지 못하였기 때문에 타 부품과의 조립시 많은 어려움이 발생되던 결점이 있었다.In the conventional press bending mold, when the U-shaped bending is performed, springback occurs, and thus the squareness cannot be maintained.

본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.The present invention has been devised to solve such a conventional drawback and the construction and operation effects by the accompanying drawings are as follows.

양측 중간 하단부면에 걸림턱(1)(1')이 형성된 벤딩펀치(2)의 하부 양측 외면에는 테이퍼(3)(3')면이 형성되고 또한 하 홀더(4)에는 홈(5)(5')을 뚫어 접시스프링(6)(6')을 설치하고 그 상부면에 스프링연결봉(7)(7')을 홈(5")(5'")이 뚫린 다이홀더(8)를 관통시켜 돌출턱(9)(9')이 형성된 벤딩다이(10)(10')를 받치게 설치하고 또한 벤딩다이(10)(10')의 상단부면에는 게이지판(11)(11')을 설치하여서 구성되어진 것으로 미설명부호 12는 제품인 것이다.Tapered (3) and (3 ') surfaces are formed on both outer surfaces of the lower sides of the bending punch (2) having the engaging jaw (1) (1') formed at the lower end surface of the both sides, and the groove (5) 5 ') to install the plate springs 6, 6' and the spring connecting rods 7 and 7 'on the upper surface of the die holder 8 through the grooves 5 "and 5'". To support the bending dies 10 and 10 'on which the protruding jaws 9 and 9' are formed, and the gauge plates 11 and 11 'on the upper end surfaces of the bending dies 10 and 10'. It is constructed by installation, and reference numeral 12 is a product.

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

상기와 같이 조립된 본원의 벤딩펀치(2)가 제품(12)을 밀고 벤딩을 시작하다가 일단 도면 제2도에 도시된 바와같이 벤딩 펀치(2)의 양측 중간 하단부면에 형성된 걸림턱(1)(1')이 벤딩다이(10)(10')를 누르게 되면 스프링연결봉(7)(7')에 힘을 전달되어 스프링연결봉(7)(7')에 의해 접시스프링(6)(6')이 압착되면서 벤딩다이(10)(10')는 하부 외측으로 돌출된 돌출턱(9)(9')에 의해 내부로 기울어지면서 벤딩펀치(2)의 하부 양측외면에 형성된 테이퍼(3)(3')을 치게됨에 따라 본래의 각도보다 깍여 형성된 테이퍼(3)(3')면의 ￡°만큼 제품(12)을 더 벤딩시킬수 있게 된 것으로 종래의 "U" 벤딩 금형으로 스프링백에 의하영 직각도를 유지못하던 것을 본원은 스프링백만큼 더 벤딩시키므로써 "U" 벤딩 제품의 정확한 직각도를 유지할수 있게 된 것이다.When the bending punch 2 of the present application assembled as described above pushes the product 12 and starts bending, as shown in FIG. 2, the locking jaw 1 formed at the middle lower end surfaces of both sides of the bending punch 2 is shown. When 1 'presses the bending dies 10 and 10', the force is transmitted to the spring connecting rods 7 and 7 ', and the plate springs 6 and 6' are driven by the spring connecting rods 7 and 7 '. ), The bending dies 10 and 10 'are inclined inward by the protruding jaws 9 and 9' protruding outward from the lower side, and the taper 3 formed on both outer sides of the lower side of the bending punch 2 ( 3 ') was able to bend the product 12 by ￡ ° of the tapered (3) (3') face, which was cut away from the original angle. The inability to maintain the squareness allows the present application to bend the spring back more, thereby maintaining the correct squareness of the "U" bending product.
