본 발명은 프레스로 성형가공된 판넬을 중첩하여 적재시에 판넬이 서로 끼이는 것을 방지하는 프레스가공 판넬의 끼임 방지 형상 성형장치에 관한 것으로서 보다 구체적으로는 프레스가공시에 판넬의 일정위치에 위치를 달리하는 끼임 방지 돌기를 형성할 수 있도록 프레스금형에 끼임 방지 형성 성형장치를 부가하여 성형된 판넬을 중첩하여 적재시에 상,하의 판넬이 서로 끼어서 발생하는 제품의 손상을 방지한 것이다. The present invention relates to a pinch-shaped shape forming apparatus of a press-processed panel which overlaps a panel formed by a press to prevent the panels from being pinched together. More specifically, the present invention relates to a press-shaped panel forming apparatus. In order to form a different anti-jamming projection by adding an anti-jamming forming apparatus to the press mold to overlap the molded panels to prevent damage to the product caused by the upper and lower panels sandwiched each other when loading.

일반적으로 프레스가공은 얇은 철판을 성형 및 절단하는 가공방법의 하나로 동일형상의 제품을 대량생산하기에 적합하고 가공속도가 우수하여 현대사회에서 선호하는 철판가공방법의 하나로 통상 제품을 완성하기 위하여서는 다단의 프레스 가공을 거치거나 용접 등의 작업을 통하여 제품이 완성된다.In general, press processing is one of the processing methods for forming and cutting thin steel plates, which is suitable for mass production of products of the same shape, and the processing speed is excellent. The product is completed through press working or welding.

그리고 프레스가공 판넬은 후공정으로 이송하기 위하여 통상 제품을 중첩하여 보관 및 운반하게 되는데 얇은 철판가공물의 중첩하는 경우 성형된 가공물이 서로 끼어지게 되고 철판가공물의 변형이 발생하여 품질이 떨어진다. And the press-processing panel is usually stored and transported by overlapping the product for transfer to the post-processing. When overlapping the thin iron sheet processing, the formed workpieces are sandwiched with each other and the deformation of the iron sheet processing occurs, the quality is reduced.

즉 프레스가공되는 제품은 금형에 의해 성형됨으로써 일측에 형상부가 돌출 되면 반대측에는 돌출부를 따라 유입부가 형성된다. In other words, the press-processed product is molded by a mold, so that a shape portion protrudes on one side and an inlet portion is formed along the protrusion on the opposite side.

따라서 프레스성형 가공 판넬은 후공정으로 이송하기 위하여 다수의 판넬을 중첩하면 도 5의 (가)에서와 같이 상,하측에 중첩된 판넬(401')(402')이 서로 끼어지게 되어 밀착되는 형상부의 변형을 초래하게 되고 후속공정에서 끼어진 철판을 분리하기 위하여 많은 시간과 노력이 낭비되는 결점이 있었다.Therefore, the press-molded panel has a shape in which the panels 401 'and 402' overlapped on the upper and lower sides are sandwiched with each other when overlapping a plurality of panels in order to transfer them to a later process. There was a defect that caused a deformation of wealth and wasted a lot of time and effort to separate the iron plate stuck in the subsequent process.

본 발명은 상기와 같은 종래의 결점을 개선코자 안출한 것으로서 프레스가공판넬의 제품기능의 영향을 받지않는 부분에 끼임 방지 돌기를 형성함으로써 제품을 중첩하여도 끼임 방지 돌기에 의해 상,하의 상,하 판넬 사이에 공간부가 형성되도록 하여 상,하 판넬이 서로 끼이지 않도록 하는 프레스가공 판넬의 끼임 방지 돌기 성형장치를 제안함으로써 판넬의 가공과 동시에 끼임 방지 돌기를 형성할 수 있도록 프레스금형에 장치하는 프레스금형의 끼임 방지 돌기 성형장치 제안함에 그 목적이 있다.The present invention has been made to improve the above-mentioned drawbacks as described above, by forming the anti-jamming projections on the parts of the press-processing panel that are not affected by the function of the product, the upper, lower, upper and lower parts by the anti-jamming projections. The press mold which is installed in the press mold to form the anti-pinching protrusion at the same time as the panel processing by suggesting the anti-pinching protrusion forming device of the press-processing panel so that the space part is formed between the panels so that the upper and lower panels are not pinched together. The object of the present invention is to propose an anti-jamming protrusion forming apparatus.

상기와 같은 목적을 달성하기 위하여 본 발명은 프레스금형의 판넬의 제품가공부 외측에 복수의 성형펀치를 장치하고 이를 선별하여 작동하도록 하여 프레스가공되는 판넬이 각각 다른 위치에 끼임 방지 돌기가 형성되도록 함으로서 상기의 목적을 달성할 수 있게 되는데 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention provides a plurality of forming punches on the outside of the product processing part of the panel of the press mold, and to operate by selecting them so that the panel being press-processed to prevent the pinching projections are formed at different positions. The purpose of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 도 2와 도 3은 본 발명의 선별돌기 성형장치를 나타낸 단면도이고 도 1에는 프레스금형에 본 발명을 적용한 실시예가 도시되어 있다.First, Figures 2 and 3 is a cross-sectional view showing a sorting protrusion forming apparatus of the present invention and Figure 1 shows an embodiment in which the present invention is applied to a press mold.

즉 본 발명은 패드(201)에 작동홈(202)(202a)을 형성하여 그 내측에 스프링(103)에 탄지되는 성형펀치(102)(102a)를 장치하고 상부금형(2)에 회전실린더(1)를 장치하여 실린더로드의 일측에 요입홈(105)과 타측에 받침부(106)를 가진 회전받침대(101)를 성형펀치(102)(102a)의 상부에 위치하게 한 구성이다.That is, according to the present invention, forming grooves 202 and 202a are formed in the pad 201 so that the forming punches 102 and 102a carried by the spring 103 are installed therein, and the upper cylinder 2 has a rotating cylinder ( 1), the rotary base 101 having the recessed groove 105 on one side of the cylinder rod and the supporting portion 106 on the other side is positioned above the forming punches 102 and 102a.

상기와 같이 되는 본 발명의 작용을 보면 도 2에서와 같이 상부금형(2)이 상사점에 위치하게 되면 패드(201)가 상부금형(2)과 일정간격 이격됨으로써 상부금형(2)에 결합된 회전받침대(101)가 패드(201)에 고정되는 성형펀치(102)(102a)의 상면와 일정간격으로 이격되어 지게 되고 상부금형(2)이 하강함에 따라 패드(201)가 먼저 하부금형(3)에 접촉하여 패드(201)의 하강이 멈추게 되고 상부금형(2)은 계속 하강하므로 도 3의 (가)회전받침대(101)의 하면에 형성된 받침부(106)에 성형펀치(102)를 접촉하여 성형펀치(102)가 하강하고 타측의 성형펀치(102a)는 요입홈(105)의 내측으로 투입되어 회전받침대(101)에 접촉하지 않게 되며 받침부(106)에 접촉한 성형펀치는 가공판넬(4)을 가압함으로써 가공판넬(4)에 끼임 방지 돌기(404)를 형성하게 되게 된다.When the upper mold 2 is located at the top dead center as shown in FIG. 2, the pad 201 is coupled to the upper mold 2 by being spaced apart from the upper mold 2 by a predetermined interval. The rotary base 101 is spaced apart from the upper surface of the forming punch (102) (102a) is fixed to the pad 201 at regular intervals, and as the upper mold (2) is lowered, the pad (201) first lower mold (3) As the lowering of the pad 201 is stopped and the upper mold 2 continues to descend, the molding punch 102 is brought into contact with the supporting part 106 formed on the lower surface of the rotating base 101 of FIG. The forming punch 102 is lowered and the forming punch 102a on the other side is introduced into the recessed groove 105 so that the forming punch 102 does not come into contact with the rotary base 101, and the forming punch in contact with the supporting part 106 is processed by a processing panel ( By pressing 4), the jamming projection 404 is formed in the processing panel 4.

프레스의 1행정의 하강 및 승강 후에 회전실린더(1) 구동하여 회전받침대(101)를 180° 회전시킴으로써 회전받침대의 하면에 형성된 받침부(106)과 요입홈(105)의 위치를 바꾸어 상부금형을 하강시키면 도 3의 (나)에서와 같이 성형펀 치(102a)가 받침부(106)에 접촉하고 타측의 성형펀치(102)는 요입홈에 위치하게 되므로 이웃하는 성형펀치(102)(102a)를 교차로 가압하여 가공판넬에 형성되는 끼임 방지 돌기의 위치를 다르게 형성할 수 있게 되며 이를 반복함으로써 가공되는 판넬에 형성되는 끼임 방지 돌기가 교차로 형성되는 것이다.After lowering and elevating the stroke of the press, the rotary cylinder 1 is driven to rotate the rotary base 101 by 180 °, thereby changing the positions of the base 106 and the recessed groove 105 formed on the bottom of the rotary base. When lowered, the forming punch 102a contacts the supporting portion 106 as shown in FIG. 3B, and the forming punch 102 on the other side is positioned in the recessed groove, so that the forming punch 102 and 102a are adjacent. By pressing the crossover to be able to form different positions of the anti-jamming projection formed on the processing panel and by repeating this is to form an intersection of the anti-jamming projection formed on the panel to be processed.

한편 본 발명은 한 쌍의 성형펀치(102)(102a)를 장치하고 회전받침대(101)를 180°회전하여 끼임 방지 돌기(404)를 형성하는 것을 실시예로 하고 있으나 다수의 성형펀치를 장치하고 회전실린더 회전각도를 다 분할하여 회전시키면 가공판넬에 형성되는 끼임 방지 돌기의 위치를 보다 다변화할 수 있음을 미리 밝혀둔다.Meanwhile, the present invention provides a pair of forming punches 102 and 102a and forms a pinch preventing protrusion 404 by rotating the rotation base 101 by 180 °, but using a plurality of forming punches. It is found in advance that by dividing the rotation angle of the rotation cylinder, the position of the jam prevention protrusion formed on the processing panel can be more diversified.

미설명 부호 104는 부싱, 301은 성형펀치 홈이다.Reference numeral 104 denotes a bushing and 301 denotes a forming punch groove.

상기와 같이 되는 본 발명은 끼임 방지 돌기 형성장치를 프레스금형에 부가하여 장치함으로써 끼임 방지 돌기를 형성하기 위한 별도의 가공공정이 필요치 않아 사용이 편리하고 다수의 성형펀치를 장치하고 회전실린더의 회전각도를 제어하면 가공판넬의 다른 위치에 끼임 방지 돌기를 형성할 수 있으므로 가공된 판넬의 보관 및 운반하기 위하여 판넬을 중첩하여도 판넬이 끼이는 것을 방지하여 후속작업이 편리하고 작업자의 작업량을 줄여 생산성이 우수한 이점이 있다.The present invention as described above is easy to use and do not need a separate processing step for forming the anti-jamming projection by adding the anti-jamming projection forming apparatus to the press mold, it is easy to use and equipped with a number of forming punches and the rotation angle of the rotating cylinder The control panel can prevent jamming projections at different positions of the processing panel, so it is possible to prevent the panel from being stuck even if the panels are overlapped for storing and transporting the processed panel. There is an excellent advantage.
