본 고안은 프레스 금형의 소재 이송장치에 관한 것으로 특히 상홀더가 승, 하강함에 따라 소재가 자동적으로 이송되도록한 프레스 금형의 소재 이송장치에 관한 것이다.The present invention relates to a material conveying apparatus of a press die, and more particularly, to a material conveying apparatus of a press die for automatically conveying the material as the upper and lower holders.

종래의 프레스 금형에서 사용하는 소재 이송장치는 대부분 금형과 별도로 제작되는 관계로 제작비가 결국 비싸지게 되는 문제점이 있었다. 그러므로 제작비를 줄이기 위하여 별도의 소재 이송장치를 제작하지 않고 작업자가 간단한 수공구를 가지고 직접소재를 이송시킴으로서 안전사고의 위험성을 갖고 있었다.The material transfer apparatus used in the conventional press mold has a problem that the production cost is eventually expensive because most of the material transfer device is manufactured separately from the mold. Therefore, in order to reduce the manufacturing cost, the worker had to carry the material directly with a simple hand tool without making a separate material conveying device, thereby having a risk of safety accident.

본 고안은 이러한 문제점을 해결하기 위하여 상홀더와 승, 하강시 캠(Cam)과 기어, V-벨트에 의해 소재가 자동으로 이송되도록 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention is designed to automatically transfer the material by the upper and lower cams, gears, and V-belts.

제1도는 본 고안에 따른 평면도이고, 제2도는 본 고안에 따른 정면도 인것으로 상홀더(1)의 저면에 펀치(22)의 일측면을 가공하여 수개의 치차(22a)를 형성하고, 펀치와 일정간격을 둔 상홀더(1)의 저면에 구멍(1a)을 뚫어 펀치(22)보다 길이가 긴 쿠션핀(16)을 홀더 상측에서 하측방향으로 삽입시켜 홀더 저면으로 하향 돌출되는 쿠션핀(18)의 선단에 스프링(17)을 끼운뒤 와셔(16)을 끼워 와셔가 쿠션핀에서 이탈되지 않게한다.FIG. 1 is a plan view according to the present invention, and FIG. 2 is a front view according to the present invention, in which one side of the punch 22 is formed on the bottom of the upper holder 1 to form several teeth 22a, and the punch And a cushion pin 16 which protrudes downwardly from the upper side of the holder by inserting a cushion pin 16 having a length longer than the punch 22 by drilling a hole 1a in the bottom of the upper holder 1 spaced apart from each other. Insert the spring (17) at the tip of 18) and then insert the washer (16) to prevent the washer from coming off the cushion pin.

하홀더(2) 상면으로 설치된 스트리퍼(3)의 상면에는 캠축(24)이 끼워지는 베어링을 내장한 지지대(5), (5')와 캠(4)을 설치하되, 캠(4)의 중간에 캠축(24)을 끼우고, 캠축(24)의 양단을 힌지편(6), (6')의 지지대(5), (5')에 매설된 베어링 속으로 삽입시키고 힌지편(6), (6')을 펀치(22)와 쿠션핀(18) 사이의 스트리터(3) 상면에 선정시킨다.On the upper surface of the stripper (3) installed on the upper surface of the lower holder (2), the support (5), (5 ') and the cam (4) having a bearing in which the cam shaft (24) is fitted are provided, but the middle of the cam (4) Insert the camshaft 24 into the bearing, and both ends of the camshaft 24 are inserted into the bearings embedded in the hinge pieces 6, the supports 5, 5 'of the 6', and the hinge pieces 6, 6 'is selected on the upper surface of the streeter 3 between the punch 22 and the cushion pin 18.

상기의 캠축(24)에 결합된 캠(4)은 후단부를형으로 절곡시켜 캠축의 후단부와 스트리퍼(3)와의 사이에 스프링(19)을 내설하고 캠(4) 선단에 중앙을 파내어 삽입홈(4c)을 형성한 상태에서 캠의 선단측면에 구멍(4a), (4b)을 뚫어, 그리고 캠축(4)의 양단에 V-벨트 풀리(13), (13')를 설치한 기어축(25)을 상기의 구멍(4a)으로 삽입시켜 삽입홈(4c)을 지날때 기어축(25)이 삽입홈(4c)에 위치하는 원통기어(12)을 관통하여 마주한 곳의 구멍(4b)으로 삽입시킨다.The cam 4 coupled to the camshaft 24 has a rear end portion. Bent to form a hole (4a) at the tip end side of the cam with the spring (19) interposed between the rear end of the camshaft and the stripper (3), and the insertion groove (4c) formed at the tip of the cam (4). ) And (4b), and the gear shaft 25 having the V-belt pulleys 13 and 13 'provided at both ends of the cam shaft 4 is inserted into the above-mentioned hole 4a to insert the groove 4c. When passing through), the gear shaft 25 penetrates through the cylindrical gear 12 located in the insertion groove 4c, and is inserted into the hole 4b where it faces.

그리고 스트리퍼(3)상에는 캠(4)의 선단을 받혀들수있도록 두개의 지지핀(3a), (3b)을 상향돌출시킨다.On the stripper 3, two support pins 3a and 3b are projected upward to support the tip of the cam 4.

그리고 하홀더(2)의 소재 진입로(23)측의 상면을 오목하게 파내어 그내부에 로울러(11), (11')를 설치하여 상면보다 약간 튀어나오도록 설치 로울러(11), (11')의 원주면이 하홀더(2)의 로울러 설치용 홀이 파여진 하홀더(2)의 가로변측단에도 홈(2a), (2b)를 파내고 여기에서 하홀더(2)의 바닥으로 관통되는 구멍을 뚫어 스프링(21), (21')이 끼원진 압축핀(2)을 상기의 구멍으로 끼워 압축핀(20)의 선단이 홈(2a), (2b) 위로 돌출되게 하고 상로울러(10), (10')와 V-벨트(14), (14')가 설치 로울러축(3)의 양측으로형상의 압측판(7), (7')을 설치하되 스프링(21), (21')을 내장한체 하홀더(2)에 내설된 상기의 압축핀(20), (20')의 상단을 압축핀(7), (7')에 체결시켜 고정한다. 이러한 상, 하 로울러(10), (10'), (11), (11')가 소재(23)의 진입상태를 평행하게 유지시켜 준다.Then, the upper surface of the lower holder 2 in the material entry path 23 is recessed and the rollers 11 and 11 'are installed therein so as to protrude slightly from the upper surface of the lower rollers 11 and 11'. The circumferential surface of the grooves 2a and 2b are also excavated in the horizontal side end of the lower holder 2 where the roller mounting holes of the lower holder 2 are dug, and the holes penetrated to the bottom of the lower holder 2 Drilled through the compression pin (2), the spring (21), (21 ') is inserted into the hole so that the tip of the compression pin 20 protrudes over the groove (2a), (2b) and the roller (10), (10 '), V-belts (14), (14') to both sides of the mounting roller shaft (3) The upper ends of the compression pins 20 and 20 'installed in the lower holder 2 in which the pressure side plates 7 and 7' of the shape are installed, but the springs 21 and 21 'are incorporated. Is fixed to the compression pins (7), (7 '). The up and down rollers 10, 10 ', 11, and 11' keep the entry state of the material 23 in parallel.

이러한 구성으로 이루어진 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made of such a configuration as follows.

최초 즉 소재를 가공하지 않는 상태에서는 캠(4)이 제2도의 지지핀(3a), (3b)에 받혀져 수평을 유지하고 있다가 기계적인 구동에 의해 제3도의 (a)에서와 같이 상홀더(1)가 하강하면 펀치(22)의 길이보다 긴 쿠션핀(18)이 먼저 캠(4)의 후단부를 누르게 된다.In the state that the material is not processed for the first time, the cam 4 is supported by the support pins 3a and 3b of FIG. 2 and is kept horizontal. When the holder 1 is lowered, the cushion pin 18 longer than the length of the punch 22 presses the rear end of the cam 4 first.

이때 상홀더의 스프링(17) 탄성력이 하홀더의 스프링(19) 탄성력 보다 강해서 캠(4) 후단부의 스프링(19)이 압축되면서 캠(4)의 선단부는 지지대 캠축(24)를 중심으로 제3도의 (a)의 화살표와 같은 방향으로 회동함으로서 캠의 원통기어(12)가 펀치(22) 측면 치차(22a)에서 분리된 상태가 되고, 펀치(22)는 상홀더(1)의 하강으로 하홀더(2)와 스트리퍼(3) 소재(23)를 타발하게 된다.At this time, the elastic force of the spring 17 of the upper holder is stronger than the elastic force of the spring 19 of the lower holder, so that the spring 19 of the rear end of the cam 4 is compressed, so that the front end of the cam 4 has a third axis around the support cam shaft 24. By rotating in the same direction as the arrow in Fig. (A), the cylindrical gear 12 of the cam is separated from the punch 22 side gear 22a, and the punch 22 is lowered to the lower side of the upper holder 1. The holder 2 and the stripper 3 material 23 is punched out.

타발이 끝난후 상홀더(1)가 상승할때 (b)에서 보는 바와같이 펀치(22)는 스트리퍼(3)에 빠져나오게 되고 압축되었던 쿠션핀(18)도 스프링(17)이 복원력에 의해 캠(4)의 후단부를 쿠션핀(18)으로 압축하면서 최초의 위치로 빠져나온다.When the upper holder 1 rises after the punching is finished, as shown in (b), the punch 22 is pushed out of the stripper 3, and the cushion pin 18, which has been compressed, also has the spring 17 being cambed by the restoring force. The rear end of (4) is pushed out to the initial position while compressing with the cushion pin 18.

이때 펀치(22)가 소재(23)에서 분리되는 순간부터는 쿠션핀(18)의 스프링(17)력보다 캠(4)의 스프링(19)력의 복원력이 캠(4)이 복귀하게 된다. 선단부의 원통기어(12)가 상승하는 펀치(22)의 치차(22a)와 맞물림되면서 화살표 방향으로 회전하여 V-벨트 풀리(13), (13')를 회전시킴에 따라 이회전력이 V-벨트(15), (15')를 통해 로울러축(9)에 전달되어 상로울러(10), (10')를 구동하게 되므로 소재(23)는 구동하는 상, 하로울러(10), (10'), (11), (11')의 밀착력에 의해 자동으로 이송하게 된다.At this time, from the moment the punch 22 is separated from the material 23, the cam 4 returns the restoring force of the spring 19 force of the cam 4 rather than the spring 17 force of the cushion pin 18. As the cylindrical gear 12 of the tip end engages with the gear 22a of the punch 22 that rises, it rotates in the direction of the arrow to rotate the V-belt pulleys 13 and 13 ', thereby causing the V-belt to rotate. It is transmitted to the roller shaft 9 through (15) and (15 ') to drive the upper rollers (10) and (10'), so the material (23) drives the upper and lower rollers (10) and (10 '). ), (11), (11 ') is automatically transferred by the adhesion force.

이러한 소재(23)의 이송간격을 펀치(22)의 치차(22a)와 캠의 원통기어(12)의 접촉시간에 따라 변화되므로 제품설계시에 이를 설정하면 소재의 이송간격을 조정될 수 있다.Since the feed interval of the raw material 23 is changed according to the contact time of the gear 22a of the punch 22 and the cylindrical gear 12 of the cam, the feed gap of the raw material can be adjusted by setting it at the time of product design.

따라서 소재(23)가 펀지(22)를 향해 일정간격으로 이송하면 상홀더(1)가 다시 내려와 소재(23)를 연속적으로 타발하게 된다.Therefore, when the material 23 is transferred to the punch 22 at a predetermined interval, the upper holder 1 comes down again to continuously punch the material 23.

상기의 설명에서 압축판(7), (7')은 압축전(20), (20')에 끼워진 스프링(21), (21')에 의해 상로울러(10), (10')를 항상 하로울러(11), (11')에 밀착시켜 소재와의 마찰력을 크게하는 작용을 한다.In the above description, the compression plates 7 and 7 'always keep the upper and lower rollers 10 and 10' by the springs 21 and 21 'fitted in the pre-compression 20 and 20'. In close contact with the rollers 11 and 11 ', the friction force with the material is increased.

이와같이 본 고안은 타발 작업후 상승하는 펀치(22)의 치차(22a)와 캠(4)에 설치된 원통기어(12)의 맞물림으로 인해 구동하는 상, 하 로울러(10), (10'), (11), (11') 사이의 마찰력으로 소재(23)가 일정간격으로 자동이송함에 따라 외부에 별도의 소재 이송장치를 설치할 필요가 없어 프레스 금형 제작시 원가 절감의 효과를 얻을 수 있는 것이다.Thus, the present invention is driven by the engagement of the gear 22a of the punch 22 rising after the punching operation and the cylindrical gear 12 installed on the cam 4, up and down rollers 10, 10 (10 '), ( 11), the material 23 is automatically transferred at regular intervals by the friction force between (11 '), there is no need to install a separate material transfer device on the outside it is possible to obtain a cost reduction effect when manufacturing the press mold.
