제5도는 제4도의 상태에서 상부 가압력의 해제직후 제품탈형 상태도.Figure 5 is a state diagram of the product release immediately after the release of the upper pressing force in the state of FIG.

제6도는 상부슈우가 패드가 완전복귀 되고 스톱퍼도 복귀된 상태도.6 is a state in which the upper shoe is completely returned to the pad and the stopper is returned.

본 고안은 스톱퍼를 이용한 드로잉 성형장치에 관한 것으로 드로잉 작업시 패드의 강한 압력에 의해 제품의 코어부위가 터짐을 방지하기 위한 것이다.The present invention relates to a drawing molding apparatus using a stopper to prevent the core portion of the product burst by the strong pressure of the pad during the drawing operation.

종래의 드로잉 성형장치는 제1도에서와 같이 패드(2)의 연에 다이(3)가 결합되고 상부슈우(1)와 패드(2)사이에는 스프링(4)이 탄지되어 간격(5)을 갖도록 구성되어 있고, 다이(3)의 걸림턱에 패드(2)가 걸려져서 제한을 받기 때문에 다이(3)가 하강하여 쿳션반발에 의해 코어부(7)가 터지는 일이 많고 드로잉 성형시에 패드(2)의 스프리(4)힘이 균등하지 않아 제품의 평탄도가 나빠지는 문제점이 있으며 이를 감안해서 패드스프링의 힘을 강하게 할수도 있으나 종래의 구성으로서는 이들의 반발력을 흡수하거나 억제할수가 없고 블랭크홀더(6)의 쿳션력과 패드 스프링(4)의 강한 반발력에 의해 취출시 제품에 손상을 주었으며 부득이 공정추가로 후처리하여야만 했었다.In the conventional drawing molding apparatus, as shown in FIG. 1, the die 3 is coupled to the edge of the pad 2, and the spring 4 is supported between the upper shoe 1 and the pad 2 so that a gap 5 is formed. Since the pad 2 is caught by the catching jaw of the die 3 and is restricted, the die 3 is lowered and the core portion 7 is often popped due to the cushioning reaction. (2) Spreads of (2) have a problem that the flatness of the product is poor because the force is not equal, and in view of this, the strength of the pad spring can be strengthened, but in the conventional configuration, the repulsive force cannot be absorbed or suppressed. Due to the cushioning force of the blank holder 6 and the strong repulsive force of the pad spring 4, the product was damaged at the time of taking out.

본 고안은 이러한 종래의 결점을 보완하기 위해 패드 및 블랭크홀더에서 생기는 강한 반발력을 저지할 수 있는 스톱퍼장치를 안출하여 제품에 정도이상의 압력을 받지않게 한 것으로 이를 첨부도면에 의해서 상세히 설명하면 다음과 같다.The present invention devised a stopper device capable of preventing the strong repulsion force generated from the pad and the blank holder to compensate for the above-mentioned drawbacks so that the product is not subjected to more than enough pressure, which will be described in detail by the accompanying drawings as follows. .

패드 (2) 양측에 플렌지(8)를 일체로 형성하고 상부슈우(1) 양쪽에 밀핀(9)을 스프링(10)으로 탄지되게 유착시켜 패드플랜지(8)의 안내공(11)에 끼워주며 블랭크홀더(6) 양측에 형성된 형 요구(12)에ㄴ형 스톱퍼(13)를 좌,우 회동이 용이하게 유착하여 요구(12)의 경사면(14) 쪽으로 회동될 수 있게 스프링(15)으로 탄지시키며 패드플랜지(8)의 외측에는 상,하 탄동식 제어핀(16)을, 안내공(11) 하단 일측에는 고정편(17)을 형성하여 이들사이의 공간(18)에 스톱포(13)의 상단부가 괘착될 수 있게 한 것이다.The flanges (8) are integrally formed on both sides of the pad (2), and the pins (9) are firmly adhered with the spring (10) on both sides of the upper shoe (1) to be inserted into the guide holes (11) of the pad flange (8). The stopper 13 of the mold request 12 formed on both sides of the blank holder 6 is easily attached to the left and right pivots so that the spring stop 15 can be rotated toward the inclined surface 14 of the request 12. The pad flange 8 has an upper and lower ballistic control pin 16 on the outside and a fixing piece 17 on one side of the lower end of the guide hole 11 to form a stop cloth 13 in the space 18 therebetween. The upper end of the can be fixed.

이와 같이 된 고안은 상부슈우(1)가 들려있는 제3도의 상태에서는 스톱퍼(13)가 스풀이(15)에 의해 외측으로 제쳐져 있게 된다.In this design, the stopper 13 is pulled outwardly by the spool 15 in the state of FIG. 3 in which the upper shoe 1 is lifted.

이상태에서 상부슈우(1)가 하강하면 먼저 다이(3)와 밀핀(9)이 하강하게 되고 스프링(4)은 압축되면서 패드(2)를 함게 하강시키게 되며 다이(3)가 제품을 눌려줌에 의해 블랭크홀더(6)가 하강하게 되므로 제품은형으로 드로잉 된다.In this state, when the upper shoe 1 is lowered, the die 3 and the mill pin 9 are first lowered, and the spring 4 is compressed to lower the pad 2 together, and the die 3 presses the product. Since the blank holder 6 is lowered by the product, It is drawn as a type.

이렇게 블랭크홀더(6)가 다이(3)에 의해 눌려서 더이상 내려가지 않게 되는 즉시, 밀핀(9)이 스톱퍼(13)를 눌러주고 스톱퍼(13)는 제4도의 상태처럼 회동하여 그 상단부가 제어편(16)을 통과하여 고정핀(17)에 걸려지므로 패드(2)가 더이상 하강할 수 없도록 받쳐주게 된다.As soon as the blank holder 6 is pressed by the die 3 and no longer descends, the mil pin 9 presses the stopper 13 and the stopper 13 rotates as shown in FIG. Passed through the (16) is fixed to the pin 17 so that the pad (2) is supported so that it can no longer descend.

그러므로 제품은 다이(3)에 의해 눌려지는 부위와 패드(2)에 의해 눌려지는 부위가 전체적으로 균등한 평활면이 유지되고 제품의 플렌지부가 정도이상의 가압력에 의해 터지는 현상이 방지되는 것이다.Therefore, the product is to maintain the even surface where the portion pressed by the die (3) and the portion pressed by the pad (2) as a whole, and the phenomenon that the flange portion of the product is prevented from being pushed by more than a pressing force.

이상태에서 상부슈우(1)에 가압력이 해제되면 블랭크 홀더(6)의 하단을 받쳐주는 쿳션핀의 복귀력에 의해 제5도의 상태처럼 블랭크홀더(6)의 스톱퍼(13)가 패드(2)를 밀고 상승하게 되고 패드(2)는 상부슈우(1)를 상승시키므로 제품이 이들의 상승력에 의해 탈형되며 그즉시 압축되어 있던 패드 스프링(4)의 복귀력에 의해 상부슈우(1)가 다시 상승하므로 밀핀(9)과 다이(3)가 함께 상승되고 스톱퍼(13)는 제어핀(16)에서 이탈되어 제6도의 상태처럼 원상태로 복귀되는 것으로서 제품은 드로잉 성형이 완료되는 것이다.In this state, when the pressing force is released to the upper shoe 1, the stopper 13 of the blank holder 6 lifts the pad 2 as shown in FIG. 5 by the return force of the cushion pin that supports the lower end of the blank holder 6. The upper shoe 1 is pushed up and the pad 2 raises the upper shoe 1 so that the product is demoulded by their lifting force and the upper shoe 1 is raised again by the return force of the pad spring 4 which was immediately compressed. The mill pin 9 and the die 3 are raised together and the stopper 13 is released from the control pin 16 and returned to its original state as shown in FIG.

이렇게 된 본 고안은 패드(2) 양단의 플렌지(8)에 천공된 안내공(11)에 상부슈우(1)의 밀핀(9)을 관통시켜 이들이 하강시에 블랭크홀더(6)의 스톱퍼(13)을 져쳐서 패드(2)를 받쳐주게 하므로서 정도이상의 가압현상이 방지되어 제품전체의 균일한 평탄도가 유지되고 성형코너부위의 처짐을 막을수 있어 재품의 손상없이 성형할 수 있는 효과가 있는 것이다.In this way, the present invention penetrates the mil pin 9 of the upper shoe 1 through the guide hole 11 drilled in the flange 8 at both ends of the pad 2 so that the stopper 13 of the blank holder 6 is lowered when they descend. By pressing the pad 2 to support the pad 2, the pressure phenomenon of the degree is prevented, and the flatness of the whole product is maintained and the sagging of the molding corner can be prevented, so that the molding can be performed without damaging the product.
