Description

Structure of natural and synthetic leather perforator {omitted}

본 고안은 자동차시트커버를 제작하는 천연피혁 및 합성피혁의 표면에 미관과 통기성을 위하여 일정한 간격으로 형성되는 다수 천공구의 내주면을 깔끔하게 천공함으로서, 상기 다수 천공구의 윤곽을 뚜렷하고 깔끔하게 형성할 수 있는 천공기를 제공하려 하는 것이다.The present invention neatly perforates the inner circumferential surface of a plurality of perforations formed at regular intervals for aesthetics and breathability on the surface of natural leather and synthetic leather for manufacturing a car seat cover, it is possible to clearly and neatly form the outline of the perforator To provide a perforator.

자동차시트커버를 제작하는 천연피혁 및 합성피혁의 표면에 일정한 간격으로 형성되는 다수의 천공구를 천공하기 위한 종래의 천공기는, 도 1에 도시한 바와 같이 천공된 폐기물을 배출하는 배출구(34)가 측면에 형성된 다수의 펀치(20)를 고정판(32)의 하부에 설치한 것이 일반적이다.Conventional perforator for drilling a plurality of perforations formed at regular intervals on the surface of the natural leather and synthetic leather for manufacturing a car seat cover, as shown in Figure 1 is an outlet 34 for discharging the perforated waste It is common to install a plurality of punches 20 formed on the lower side of the fixed plate 32.

그런데, 이와 같은 천공기로 천연피혁 및 합성피혁에 다수의 천공구를 형성하기 위하여 천공작업을 반복하여 할 경우, 천공된 천연피혁 및 합성피혁의 폐기물이 배출구(34)를 통하여 일부 배출되기는 하지만 반복적인 천공작업으로 인하여 천공된 천공폐기물이 다수의 펀치(20)내부에 쌓이게 되어 배출되지 않는 단점이 있었고, 상기와 같이 내부에 천공된 천공폐기물이 쌓여진 다수의 펀치(20)로 천공작업을 함으로서 천공구의 내주면이 깔끔하게 천공되지 않는 문제점이 있었다.By the way, when the punching operation is repeated to form a plurality of drilling tools in the natural leather and synthetic leather with such a perforator, the waste of the perforated natural leather and synthetic leather is partially discharged through the outlet 34, but it is repeated Due to the drilling operation, there was a disadvantage that the punched punch waste was accumulated in the plurality of punches 20 and not discharged, and the punching tool was carried out with a plurality of punches 20 in which the punched wastes stacked therein were stacked as described above. There was a problem that the inner circumference of the perforated neatly.

이에 본 고안은 천공구의 내주면을 깔끔하게 천공함으로서, 천연피혁 및 합성피혁의 표면에 일정한 간격으로 천공되는 다수 천공구 전체의 윤곽을 뚜렷하고 깔끔하게 형성할 수 있는 천연피혁 및 합성피혁 천공기를 제공하는데 그 목적이 있다.Therefore, the present invention neatly perforates the inner circumferential surface of the drilling tool, to provide a natural leather and synthetic leather perforator that can clearly and neatly form the outline of the entire number of drilling tools drilled at regular intervals on the surface of the natural leather and synthetic leather There is this.

본 고안은 다수의 펀치내부에 이젝터 핀을 각각 설치하여 천연피혁 및 합성피혁의 표면에 다수의 천공구를 천공한 후 다수의 펀치내부에 수용된 천공된 폐기물을 이젝터 핀으로 외부로 배출시키고 난 다음 다시 천공동작을 수행함으로서, 다수 천공구의 내주면이 깔끔하게 천공되어 윤곽이 뚜렷한 다수의 천공구를 천연피혁 및 합성피혁의 표면에 형성할 수 있는 것을 특징으로 한다.The present invention installs ejector pins in each of the plurality of punches, drills a plurality of drill tools on the surface of natural leather and synthetic leather, and then discharges the punched waste contained in the plurality of punches to the outside using ejector pins. By performing the punching operation, the inner circumferential surface of the plurality of drilling tools is neatly drilled to form a plurality of drilling tools having a clear outline on the surface of natural leather and synthetic leather.

이상에서와 같이 본 고안의 천연피혁 및 합성피혁 천공기의 구조는, 천연피혁 및 합성피혁의 표면에 윤곽이 뚜렷하고 깔끔한 다수의 천공구를 형성할 수 있는 효과를 갖는 것이다.As described above, the structure of the natural leather and synthetic leather perforator of the present invention has the effect of forming a plurality of perforations having a clear and clean contour on the surface of the natural leather and synthetic leather.

이하, 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the present invention as follows.

도 2는 본 고안에 따른 천연피혁 및 합성피혁 천공기의 구조와 작업공정을 도시한 단면도이다.Figure 2 is a cross-sectional view showing the structure and working process of the natural leather and synthetic leather perforator according to the present invention.

이에 도시한 바와 같이 천공기본체(10)는 상판(12)과 하판(26)을 좌, 우측에 설치된 가이드봉(16)으로 연결하여 일체로 형성되어 있다.As shown in the drawing, the drilling base 10 is integrally formed by connecting the upper plate 12 and the lower plate 26 with guide rods 16 provided on the left and right sides.

상기 상판(12)의 하부에는 다수의 이젝터 핀(18)이 설치되어 있다.A plurality of ejector pins 18 are provided below the upper plate 12.

이동판(14)은 좌, 우측에 형성된 부싱(22)에 천공기본체(10)의 좌, 우측에 설치된 각각의 가이드봉(16)이 삽입되어 상판(12)과 하판(26)사이에 설치되며, 이와 같이 설치된 이동판(14)의 좌, 우측 부싱(22)의 각각 하부에는 각각의 스프링(24)이 설치됨과 아울러 좌, 우측에 설치된 각각의 가이드봉(16)에 삽입되어 상, 하로 동작시킬 수 있도록 구성되어 있다.The moving plate 14 is installed between the upper plate 12 and the lower plate 26 by inserting respective guide rods 16 installed at the left and right sides of the drilling base 10 into the bushings 22 formed at the left and right sides. In addition, each spring 24 is installed at each lower portion of the left and right bushings 22 of the movable plate 14 installed as described above, and is inserted into the respective guide rods 16 installed at the left and right sides to move up and down. It is configured to be.

이동판(14)의 하부에는 다수의 펀치(20a)가 설치되어 있으며, 다수의 펀치(20a)의 관통된 내부에는 상판(12)의 하부에 설치된 다수의 이젝터 핀(18)이 밀접하게 결합되어 있다.A plurality of punches 20a are installed in the lower portion of the moving plate 14, and a plurality of ejector pins 18 installed in the lower portion of the upper plate 12 are closely coupled to each other through the plurality of punches 20a. have.

이와 같이 구성된 천연피혁 및 합성피혁 천공기의 천공공정을 설명하면 다음과 같다.Referring to the drilling process of the natural leather and synthetic leather punching machine configured as described above are as follows.

도 2의 (A)에 도시한 바와 같이 천공기본체(10)를 구성하는 하판(26)의 상부에 피혁(28)을 올려 놓고, 도 2의 (B)에 도시한 바와 같이 이동판(14)을 가압함으로서 상기 이동판(14)이 하강하며 하부에 설치된 다수의 펀치(20a)가 피혁(28)의 표면을 펀칭한 후, 이동판(14)을 가압하는 가압력을 해지하게 되면, 도 2의 (C)에 도시한 바와 같이 이동판(14)이 스프링(24)의 탄력에 의하여 상승됨과 동시에 다수 펀치(20a)의 내부와 밀접하게 결합된 다수의 이젝터 핀(18)이 다수 펀치(20a)의 내부에 수용되는 천공폐기물(36)을 펀치(20a)의 외부로 밀어내도록 구성된 것이다.As shown in FIG. 2A, the leather 28 is placed on the upper part of the lower plate 26 constituting the drilling base 10, and the moving plate 14 is shown in FIG. 2B. When the moving plate 14 is lowered by pressurizing and the plurality of punches 20a installed at the bottom punch the surface of the leather 28, the pressing force for pressing the moving plate 14 is released. As shown in (C), the plurality of ejector pins 18 coupled with the inside of the plurality of punches 20a are simultaneously lifted by the elasticity of the spring 24 and the plurality of punches 20a. It is configured to push the perforated waste 36 accommodated in the outside of the punch 20a.

상기와 같은 구성으로 천공작업 후, 다수 펀치(20a)의 내부가 항상 비워진 상태로 다음 천공공정을 수행함으로서, 천연피혁 및 합성피혁의 표면에 내주면이 깔끔하게 컷팅되어 윤곽이 뚜렷한 다수의 천공구를 형성할 수 있는 것이다.After the drilling operation as described above, by performing the next drilling process with the interior of the plurality of punch (20a) is always empty, the inner circumferential surface is neatly cut on the surface of natural leather and synthetic leather to form a number of perforations with a clear outline You can do it.
