Description
본 발명은 프레스 금형용 스트리핑 장치에 관한 것으로, 보다 상세하게는 프레스 금형에서 펀치를 이용한 타공 작업에 있어서 타공 후에 펀치의 후퇴 이동시 상기 펀치와 판넬을 분리시켜 판넬이 딸려 올라가는 것을 방지하는 스트리핑 장치의 구조를 개선함으로써, 작업의 생산성 및 효율성을 향상시킬 수 있도록 발명한 것이다.The present invention relates to a stripping apparatus for a press die, and more particularly, in a punching operation using a punch in a press die, a structure of a stripping apparatus that separates the punch and the panel and prevents the panel from coming up during the retreat movement of the punch after the punching. By improving, the invention is invented to improve the productivity and efficiency of the work.
일반적으로 금형용 캠 유니트는 프레스 금형에 장착되어 수직 왕복 운동의 작업방향을 바꾸어 각도운동이 가능하도록 한 것으로서, 도 1에서와 같이 박스형의 캠 베이스(1)의 저면에는 전,후 방향으로 슬라이드 이동 가능한 캠 슬라이더(3)가 장착되고, 캠 슬라이더(3)에는 리턴 스프링(5)을 삽입할 수 있는 스프링홈(6)이 형성되며, 하부에는 캠 드라이버(7)가 설치된다.In general, the cam unit for the mold is mounted on the press mold to change the working direction of the vertical reciprocating motion so that the angular motion is possible. As shown in FIG. The cam slider 3 is mounted, a spring groove 6 into which the return spring 5 can be inserted is formed in the cam slider 3, and a cam driver 7 is installed below.
상기와 같이 구성된 캠 유니트의 작동과정은 도 2에서와 같이 캠 베이스(1) 전체가 하강하면서, 캠 슬라이더(3) 저면의 슬라이드홈(8)이 캠 드라이버(7) 상면의 슬라이드판(9)을 따라 가이드이동하면, 리턴 스프링(5)은 탄성을 갖고 압축되고, 캠 슬라이더(3)는 전진하여 펀치(16)가 지그(14)에 고정 장착된 판넬을 펀칭하도록 구성되어 있다.In the operation process of the cam unit configured as described above, as shown in FIG. 2, as the entire cam base 1 is lowered, the slide groove 8 of the bottom of the cam slider 3 has the slide plate 9 on the upper surface of the cam driver 7. When the guide moves along, the return spring 5 is elastically compressed and the cam slider 3 is advanced so that the punch 16 punches the panel fixedly mounted to the jig 14.
그러나, 상기한 종래 캠 유니트는, 리턴 스프링의 복귀탄성에 의해서만 판넬제품에 펀칭작업을 완료한 펀치를 반대 방향으로 리턴시키도록 구성되어 있어, 최근 인장강도가 증가된 고장력 강판과 같은 판넬 및 두께가 두꺼운 판넬에서는 상기 펀치와 판넬과의 마찰 저항이 커져 리턴이동에 문제가 생기는 경우가 빈번하여 고속타발이 불가능하거나 캠 슬라이더 또는 펀치가 파괴되는 문제점이 있었다.However, the above-mentioned conventional cam unit is configured to return the punch, which has completed the punching operation, to the panel product in the opposite direction only by the return elasticity of the return spring. In the thick panel, the frictional resistance between the punch and the panel is large, which causes problems in return movement, and thus, high speed punching is impossible or the cam slider or punch is broken.
따라서, 상기 문제점을 해소하기 위해 캠슬라이더를 복귀 이동시키는 리턴스프링의 탄성을 증대시켜 사용하고 있으나, 상기 탄성이 높은 스프링의 장착과 고정이 어렵고, 캠 유니트 작동 중에 상기 높은 탄성력에 의해 분리되면서 안전사고가 발생되는 폐단이 있었다.Therefore, in order to solve the above problems, the elasticity of the return spring for returning and moving the cam slider is used, but it is difficult to install and fix the spring with high elasticity, and the safety accident is separated by the high elastic force during the operation of the cam unit. There was a lung ending that occurred.
또, 상기 리턴스프링의 탄성이 높은 상태에서는 캠 슬라이더가 캠 드라이버에 최초 접촉하는 충돌 순간에 전방으로 이동되어야 하는데, 상기 리턴스프링의 탄성에 의해 부드럽게 전방으로 이동되지 않게 되어 충격력이 증가되며, 이후 캠 드라이버의 전진 이동시에도 접촉면간의 수직면압이 증가되어 접촉면의 마모 진행이 가속화되어 캠 장치의 수명을 단축시키는 문제점이 있었다.In addition, in the state where the return spring has a high elasticity, the cam slider should be moved forward at the moment of the first contact with the cam driver. The elastic force of the return spring does not move forward smoothly, so that the impact force is increased. Even when the driver moves forward, the vertical surface pressure between the contact surfaces is increased, thereby accelerating the wear progress of the contact surfaces, thereby shortening the life of the cam device.
상기와 같은 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명은 타공작업 후에 펀치와 판넬을 보다 간편하게 분리시킬 수 있도록 함과 아울러 상기 캠 슬라이더 전면에 펀치홀더와 펀치가 고정 장착된 상태에서도 판넬을 가압하는 누름부재를 교체할 수 있도록 하는데 그 목적이 있다.In order to solve the problems of the prior art as described above, the present invention allows the punch and the panel to be easily separated after the punching operation, and also pressurizes the panel even when the punch holder and the punch are fixedly mounted on the front of the cam slider. Its purpose is to be able to replace the pressing member.
본 발명의 다른 목적은, 디스크 스프링을 적용해 적층구조의 안전성을 확보하면서도 판넬의 종류에 따라서 상기 디스크 스프링의 적층구조와 개수를 조정 함으로서, 캠 슬라이더의 리턴이동이 원활히 이루어지고 펀치 작업의 효율성을 향상시킬 수 있게 한다.Another object of the present invention is to adjust the stacking structure and the number of the disk spring according to the type of the panel while ensuring the safety of the stacking structure by applying the disk spring, the cam slider smoothly the return movement and the efficiency of the punch operation To improve.
본 발명의 또 다른 목적은, 기존의 펀치홀더에 직접 장착가능하면서, 내부에 수용되는 누름부재의 장착과 분해가 간편하여 조립공정 및 사용편의성을 증대시킬 수 있고, 펀치 작업 중에 마모된 누름부재의 교체를 신속하게 수행하여 제품생산의 효율성을 증대시키도록 하는데 있다.Still another object of the present invention is to be able to directly attach to the existing punch holder, to facilitate the mounting and disassembly of the pressing member accommodated therein, thereby increasing the assembling process and ease of use, and It is to perform the replacement quickly to increase the efficiency of production.
