Description
본 발명은 트리밍 장치에 관한 것이다.The present invention relates to a trimming device.
일반적으로, 드로잉 장치는 평판상인 철판등을 소정 형상으로 가공하는 장치인 바, 상기한 드로잉 장치에는 가공 대상물인 철판을 소정 형태로 절단하는 트리밍 장치가 설치되어 있다.In general, the drawing device is a device for processing a flat plate or the like into a predetermined shape, and the drawing device is provided with a trimming device for cutting the iron plate to be processed into a predetermined shape.
이는 제1도에 도시된 바와 같이 프레스 가공이나 주조 가공으로 생산된 제품(3)을 안착시키는 트리밍 다이(trimming die)(2)와 상기한 트리밍 다이(2)에 안착된 상기 제품(3)의 소정 부분을 절삭하는 트리밍 펀치(trimming punch)(1)로 이루어져 있다.This is a trimming die 2 for seating the product 3 produced by press work or casting process as shown in FIG. 1 and of the product 3 seated on the trimming die 2 described above. It consists of a trimming punch 1 which cuts a predetermined part.
상기한 바와 같은 트리밍 장치는 제품의 외경을 소정 형상으로 절단하게 되고, 트리밍이 완료된 제품은 다시 드로잉 장치에서 형상을 완료하게 되는 바, 이는 제2도에 도시된 바와 같이 트리밍이 완료된 제품을 드로잉 다이(4)와 드로잉 펀치(5) 사이에 안착시켜 성형할 때 상기한 제품의 끝단에서 3도에 도시된 바와 같이 버(burr)(3A)가 발생하게 된다.The trimming device as described above cuts the outer diameter of the product into a predetermined shape, and the trimming finished product is completed in the drawing device again, which is a drawing die as shown in FIG. When seated and molded between (4) and the drawing punch 5, burrs 3A are generated at the end of the product as shown at 3 degrees.
즉, 상기한 드로잉 펀치(5)와 다이(4)의 인장에 의해 제품(3) 끝단이 밀려서 버(3A)가 발생되는 것이다.That is, the end of the product 3 is pushed by the tension of the drawing punch 5 and the die 4, and the burr 3A is generated.
물론, 상기한 버[3A]는 드로잉 성형 후 모따기 작업을 통해 제거하게 된다.Of course, the burr [3A] is removed through the chamfering operation after the drawing molding.
그러나, 상기한 바와 같이 트리밍 및 드로잉 공정 후 다시 모따기 작업으로 버를 제거하게 되면 작업 공정이 복잡하게 되고 이로 인해 작업 능률이 저하되는 문제점이 있다.However, when the burr is removed by the chamfering operation again after the trimming and drawing process as described above, there is a problem that the work process is complicated and the work efficiency is lowered.
따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 제품을 드로잉 공정에서 발생되는 버를 별도의 모따기 공정으로 제거하지 않도록 함으로써 드로잉 가공 공정 효율을 향상시킬 수 있는 트리밍 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a trimming apparatus that can improve the drawing processing efficiency by not removing the burrs generated in the drawing process by a separate chamfering process, to solve the above problems.
상기한 목적을 실현하기 위하여 본 발명은 트리밍 다이와 트리밍 펀치 사이에서 제품을 절단하도록 구성된 트리밍 장치에 있어서, 상기한 트리밍 펀치에 형성됨과 아울러 트리밍 다이가 끼워지도록 형성된 굽힘부와, 상기한 굽힘부의 모서리 부분에 형성됨과 아울러 드로잉 공정시에 발생되는 버의 체적만큼 제품의 끝단을 압박하여 체적 감소시키도록 구성된 챔퍼를 포함팜을 특징으로 한다.In order to achieve the above object, the present invention provides a trimming device configured to cut a product between a trimming die and a trimming punch. And a chamfer formed in the palm and configured to reduce the volume by pressing the end of the product by the volume of the burr generated during the drawing process.
제1도는 일반적인 트리밍 장치에서 제품의 트리밍 상태를 도시한 단면도.1 is a cross-sectional view showing a trimming state of a product in a general trimming device.
제2도는 제1도의 트리밍 후 드로잉된 상태의 제품을 도시한 개략 단면도.2 is a schematic cross-sectional view showing the product in the drawn state after trimming in FIG.
제3도는 드로잉 공정 후의 제품 상태를 도시한 단면도.3 is a sectional view showing a state of a product after a drawing process.
제4도는 본 발명에 따른 트리밍 장치에서 제품의 트리밍 상태를 도시한 단면도.4 is a cross-sectional view showing a trimming state of the product in the trimming device according to the present invention.
제5도는 본 발명에 따른 트리밍 공정 후 드로잉된 상태의 제품을 도시한 단면도.5 is a cross-sectional view showing a product in a state of being drawn after a trimming process according to the present invention.

제4도도는 본 발명에 따른 트리밍 장치를 도시한 단면도이고, 5도는 상기한 트리밍 후 드로잉된 제품을 도시한 단면도로서, 트리밍 다이(20)와 밀착되도록 트리밍 펀치(10)에 굽힘부(6)가 형성되어 있고, 상기한 굽힘부(6)의 모서리 부분에 드로잉 공정시에 발생되는 버(3A)의 체적만큼 제품의 끝단을 압박하여 체적 감소시키도록 구성된 챔퍼(7)가 형성되어 있다.4 is a cross-sectional view showing a trimming device according to the present invention, and FIG. 5 is a cross-sectional view showing a product drawn after the trimming, and the bent portion 6 of the trimming punch 10 is brought into close contact with the trimming die 20. Is formed, and a chamfer 7 configured to press the end of the product to reduce the volume by the volume of the burr 3A generated at the drawing step is formed in the corner portion of the bent portion 6 described above.
즉, 상기한 챔퍼(7)로 제품의 끝단을 압박하여 끝단 체적을 감소시키게 되면 상기한 제품의 드로잉 시 끝단이 당겨져도 버(3A)가 발생되지 않게 되는 것이다.That is, when the end volume is reduced by pressing the end of the product with the chamfer 7, the burr 3A is not generated even when the end is pulled during the drawing of the product.
상기한 바와 같은 본 발명의 작용 효과를 설명하면 트리밍 다이(20)에 제품을 안착시킨 후 트리밍 펀치(10)로 이를 절단하게 된다.When explaining the operation and effect of the present invention as described above, the product is placed on the trimming die 20 and then cut it with a trimming punch 10.
이때, 상기한 굽힘부(6) 및 챔퍼(7)가 제품의 절단된 끝단을 압박하여 체적을 감소시키게 된다.At this time, the bent portion 6 and the chamfer 7 to press the cut end of the product to reduce the volume.
상기한 챔퍼(7)의 체적만큼 제품의 절단 끝단을 감소시키게 되면 상기한 제품을 드로잉 가공할 때 상기한 체적만큼 제품 끝단의 여유살이 감소하게 되고, 이로 인해 제품 끝단이 인장되어도 버(3A)가 발생되지 않게 되는 것이다.When the cutting end of the product is reduced by the volume of the chamfer 7, the margin of the product end is reduced by the volume when the product is drawn, so that the burr 3A is reduced even if the product end is tensioned. It will not occur.
물론, 상기한 챔퍼(7)의 체적은 통상적인 제품의 드로잉 시 발생되는 버(3A)의 체적만큼 설정되어 있기 때문에 상기한 제품의 끝단은 모따기등과 같은 후가공이 필요없게 되는 것이다.Of course, since the volume of the chamfer 7 is set by the volume of the burr 3A generated when drawing a normal product, the end of the product does not need post-processing such as chamfering.
이상과 같이 본 발명은 제품의 트리밍 가공 시 제품 끝단을 압박하여 체적을 감소시키도록 트리밍 펀치에 챔퍼를 형성함으로써 드로잉 가공시의 작업 효율을 증대시킬 수 있는 잇점이 있는 것이다.As described above, the present invention has the advantage of increasing the work efficiency during drawing processing by forming a chamfer in the trimming punch to reduce the volume by pressing the product end during trimming of the product.
