본 고안은 해머핀 제조장치의 개량에 관한 것이다.The present invention relates to an improvement of the hammer pin manufacturing apparatus.

본 고안은 특히 본인의 선출원 고안인 실용신안등록 출원 제85-1705와 등 제 85-11006호를 발진적으로 개량할 것이 특징이다.The present invention is characterized by a radical improvement of Utility Model Registration Application Nos. 85-1705 and 85-11006, etc., which are the design proposals of the applicant.

상기 선행기술중 전자는 선제조 후집적(가공된 해머핀을 나열방향으로 정리한 다음 접착제로 붙이는 것)방식으로 특징이다.In the prior art, the former is characterized by a prefabrication post-aggregation method by arranging the processed hammer pins in a line direction and then attaching them with an adhesive.

즉, 상기 전자의 선행기술에 의하면 강철 선재를 한쌍의 평로울러 사이로 강제 통과시켜 위아래가 평활하고, 양옆이 호상 팽출면을 이루도록 예비 가공한 것을 그 선단이 중공금형의 선단 수직홈 내에 들어가게 한 다음 타격체에 의한 두부를 형성하고, 이어 반출과정에서 머리부로 부터 일정한 길이로 절단하므로서 해머핀을 만들며, 이렇게 제조된 10매, 50매 도는 100매등의 단위로 군집시키고, 각 해머핀의 측면에 접착제를 뿌려서 집속화 하는 것이다.That is, according to the former prior art, the steel wire rod is forced through a pair of rollers, the upper and lower sides are smooth, and the preliminary processing is performed so that both sides are arcuate swelling surfaces so that the tip enters the vertical groove of the hollow mold. The head is formed by a sieve, and then the hammer pin is made by cutting the head to a certain length in the process of discharging. The 10, 50 sheets prepared in this way are clustered in units of 100 sheets, and the adhesive is applied to the side of each hammer pin. Sprinkle and focus.

이같은 종래의 해머핀 제조장치에 의해 집속화 된 해머핀은 집속상태가 미흡해서 접착력이 취약하기 때문에 이를 에어해머를 장착하여 박음질 할때 불량율이 높고, 해머핀의 생산성도 낮았다.The hammer pin focused by such a conventional hammer pin manufacturing apparatus has a poor focusing state and the adhesive force is weak, so that when the air hammer is attached to it, the defect rate is high, and the productivity of the hammer pin is low.

반면에 후자는 전자의 기술을 진일보시킨 것으로서. 선절단한 소재를 수십, 수백개를 한 단위로 집속 접착과 동시에 일시예 머리부를 형성하는 것이 특징으로 되어 있다.The latter, on the other hand, is a step forward in the former technology. It is characterized by forming a temporary head at the same time as focusing adhesive bonding of dozens and hundreds of cutting materials.

그러나 이 장치는 단 한가지의 결점을 갖고 있다.However, this device has only one drawback.

즉, 집속 접착된 소재의 양단을 일거에 압타하여 머리부를 성형하는 과정에서 소재의 중앙 부분에 휨현상이 일어나는 사례가 종종 있다는 것이다.In other words, in the process of forming the head part by pressing both ends of the focused adhesive material at once, there is a case where a bending phenomenon occurs in the central portion of the material.

이러한 휨현상은 육안으로 식별이 어려울 정도로 미미하여 무시해도 무난할 것 같이 여겨지는 것이지만, 이렇게 제조된 해머핀을 에어해머에 장탄하여 사용할 때 작업뷸량의 다발이 우려되기 때문에 가급적 이면 이러한 휨현상을 배제하는 것이 중요하다.This deflection phenomenon is so small that it is difficult to discern with the naked eye, and it is considered to be negligible.However, it is important to exclude this warping phenomenon if possible because it is concerned about the bundle of work bends when using the hammer pin prepared in the air hammer. .

본 고안은 바로 이점을 개선한 것이다.The present invention is just an improvement.

이하 본 고안을 바람직한 실시예에 의거 작성한 첨부도면과 관련하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings made in accordance with a preferred embodiment.

본 고안은 소재 투입부(A)와 집속 성형부(B) (및 절단부(C))로 대별된다.The present invention is roughly divided into a material input part A and a focused molding part B (and a cut part C).

소재투입부(A)은 소재인 철사(1)를 감아 놓은 얼레(2)와, 이 얼레(2)에 감겨 있는 철사(1)를 도입하여 (해머핀의 일정2배)길이로 잘라주는 절단기(3)와, 절단기(3)에서 잘러진 해머핀소재(5)를 경사안내구(4)를 통해 집속 성형부(B)로 이송하면서 집속 성형부(B)에 투입되기 직전에 상기 해머핀 소재(5)의 외면에다가 접착제를 자연 낙하시켜 도포해 주는 접착제 공급장치(6)로 구성되어 있다.The material input part (A) is a cutting machine which cuts the length of the wire (1) wrapped around the wire (1) and the wire (1) wound around the wire (2) and cuts it to (2 times the hammer pin) the length. (3) and the hammer pin material (5) cut by the cutter (3) immediately before being introduced into the focusing forming portion (B) while transferring to the focusing molding portion (B) through the inclined guide (4) It consists of the adhesive supply apparatus 6 which apply | coats a natural fall of an adhesive agent to the outer surface of the raw material 5, and is apply | coated.

집속 성형부(B)는 소재(5)의 진행방향의 중심을 깃점으로 그 좌우측에 한꺼번에 다량의 소재(5)를 수용할 수 있도록 넓은 수용면적을 가진 윗틀(7)과 아랫틀(8)로 된 금형이 설치되어 있고, 이 금형의 윗틀(7)과 아랫틀(8)사이에는 타격체(9)가 가로방향으로 설치방향으로 끼워져 있다.Focusing molded part (B) is the upper frame (7) and the lower frame (8) having a large receiving area to accommodate a large amount of the material (5) at the left and right sides at the center of the advancing direction of the material (5) at the same time The mold is provided, and the striking body 9 is fitted in the installation direction in the horizontal direction between the upper frame 7 and the lower frame 8 of the mold.

또한, 상기 윗틀(7)과 아랫틀(8)에서 이들이 마주친 중앙선상에는 소재(5)의 진행방향으로 출입하면서 가공할 소재의 측방을 밀어서 느슨한 소재의 간격을 밀착시켜 주는 밀대(10)(10')가 결합되어 있다.In addition, on the center line that they meet in the upper frame (7) and the lower frame (8) pushes the side of the material to be processed while moving in the advancing direction of the material 5 (10) (10) to close the gap between the loose material ') Is combined.

상기한 집속 성형부(B)의 구조는 제2도 및 제3도에 상세하게 도시되어 있다.The structure of the focusing molded part B described above is shown in detail in FIGS. 2 and 3.

이들 그림에서 보듯이, 타격체(9)는 상하로 움직일수 있는 윗틀(7)과 그 하방에 고정된 아랫틀(8) (도시없으나, 윗틀과 대칭 구조이며 다만 배출대(15)만 없다)의 레일(11)에 의해 형성된 넓은 폭의 요홈(12)상에서 그림의 좌우로 진퇴하게 되며, 이 타격체(9)는 소재(5)의 일측단부를 동시에 타격하여 머리부를 형성하는 것이다.As shown in these figures, the striking body 9 has an upper frame 7 that can be moved up and down and a lower frame 8 fixed below it (not shown, but symmetrical with the upper frame, but without a discharge base 15). On the wide groove 12 formed by the rail 11 of the advancing to the left and right of the picture, the striking body 9 is to hit the one end of the material 5 at the same time to form a head.

또, 윗틀(7)과 아랫틀(8)에서 이들이 서로 마주치는 내측단 저면 또는 상면에는 소재(5)의 머리부쪽 끝부분을 물어주는 물림날(13)을 갖고 있다.Moreover, in the upper frame 7 and the lower frame 8, they have a biting blade 13 which inquires the head end part of the raw material 5 in the bottom or upper surface of the inner end where they face each other.

이 물림날(13)의 외향측에는 두부 성형에 필요한 홈(14)도 마련되어 있다.A groove 14 necessary for head molding is also provided on the outward side of the meshing blade 13.

상기한 윗틀(7)과 타격체(9) 및 반출구 (14)의 승강 또는 수평작동을 일반적으로 널리 알려져 있는 유압 또는 공압 실린더기구, 크랭크 기구 또는 캠운등 기구등의 어느 운동기구를 적용하여도 같은 효과를 거둘 수 있다.The lifting mechanism or the horizontal operation of the upper frame 7 and the striking body 9 and the discharging port 14 may be applied to any exercise device such as a hydraulic or pneumatic cylinder mechanism, a crank mechanism or a cam cloud mechanism. The same effect can be achieved.

이와같이 구성된 본 고안에 있어서, 얼레(2)에 감겨 있는 철사(11)를 절단기 (30에 당도하기 전에 바르게 펴서(로울러 고정장치등을 이용함) 절단기(3)로 보내 소정 칫수로 절단한다.In the present invention configured in this way, the wire 11 wound on the spool 2 is straightened (using a roller fixing device or the like) before being brought to the cutting machine 30 and sent to the cutting machine 3 to be cut to a predetermined dimension.

여기서 절단된 소재(5)는 경사안내구(4)의 안내로 집속성형부(B)에 투입된다. 집속성형부(B)로 투입되기 직전에서는 접착제 공급장치(6)에서 얇은 막 형태로 낙하되는 접착제가 소재(5)의 표면에 묻게된다. 이렇게 접착제가 묻은 소재(5)는 예를 들어 50매, 100매를 접속단위로 하여 분할된다. 이러한 분할은 집속 성형부(B)의 직전 위치에서 수직 승강되는 분할판(16)에 의해 달성된다.Here, the cut material 5 is introduced into the focus molding part B by the guide of the inclined guide 4. Immediately before being put into the focusing part B, the adhesive falling in the form of a thin film from the adhesive supply device 6 is buried on the surface of the material 5. Thus, the raw material 5 with adhesive is divided into 50 and 100 sheets as connection units, for example. This division is achieved by the divider plate 16 which is vertically raised and lowered at the position immediately before the focusing forming portion B. As shown in FIG.

그리하여 집속단위로 분할 투입된 소재(5)는 아랫틀(8)의 레일(11)사이에 위치한 중앙면에 가즈런히 재치된다. 이때 윗틀(7)은 들러진 상태이다.Thus, the raw material 5 divided into the focusing unit is placed on the center surface located between the rails 11 of the lower frame 8. At this time, the upper frame 7 is in a stopped state.

이어 밀대(10)(10')가 전진하면서 각 소재(5)간의 틈이 없도록 밀어서 밀착시킨 다음 윗틀(7)이 내려진다(제4도).Subsequently, the push rods 10 and 10 'are pushed to be in close contact with each other so that there is no gap between the materials 5 and then the upper frame 7 is lowered (FIG. 4).

윗틀(7)이 내려져 짓누르면 당초 원형단면이던 소재(5)는 위아래가 평활한 타원형 단면으로 변화된다(제5도). 이때 소재(5)는 동시에 윗틀(7)과 아랫틀(8)의 물림날(13)에 의해 그 양단부가 견고하게 물린다.When the upper frame 7 is lowered and crushed, the material 5, which was originally a circular cross section, is changed into an elliptical cross section with a flat top and bottom (FIG. 5). At this time, both ends of the material 5 are firmly bitten by the biting blade 13 of the upper frame 7 and the lower frame 8 at the same time.

이런 상태하에서 타격체(9)가 제6도의 화살표 방향으로 수평이동하면서 소재(5)의 양단부를 강력한 힘으로 때려 준다.Under such a state, the striking body 9 is horizontally moved in the direction of the arrow of FIG. 6, and strikes both ends of the material 5 with a strong force.

이로써 제6도에서 보듯이 물림날(13)쪽 밖으로 노출된 부분(점선표시부분)이 윗틀(7)과 아랫틀(8)의 상하방향으로 퍼지면서 머리부(21)를 이루게 된다.As a result, as shown in FIG. 6, the portion (dotted display portion) exposed outward of the bleeding blade 13 forms the head portion 21 while spreading in the vertical direction of the upper frame 7 and the lower frame 8.

이렇게 머리부(21)가 성형되고 나면 윗틀(7)은 들리고 타격체(9)는 물리나며, 이들이 원위치로 되돌아가므로 물림압력이 해제된 성형물(22)은 뒤이어 곧바로 상승하는 반출구(15)에 의해 들러진다.After the head 21 is molded in this way, the upper frame 7 is lifted and the striking body 9 is bitten, and since they are returned to their original positions, the molding 22 in which the bite pressure is released is immediately lifted out of the outlet 15. Drop by

이상과 같은 본 고안에 따르면, 선접착 후 집속 성형에 의한 강력한 접착력 때문에 제조된 집속 해머핀의 결속상태가 튼튼하여 사용하기 좋을 뿐 아니라 일시에 다량의 해머핀 제조를 실현할 수 있어서 생산성제고와 원가 절감에 크게 기여할 수가 있다.According to the present invention as described above, the binding state of the produced focused hammer pin is strong because of the strong adhesive force by focusing molding after pre-bonding, and it is possible to realize the production of a large number of hammer pins at one time, thereby improving productivity and cost reduction. Can contribute significantly.

더우기 타격시 해머핀의 어느부분에도 휨현상이 일어나지 않아 정교한 재품을 얻을 수가 있는 것이다.Moreover, the bent phenomenon does not occur in any part of the hammer pin when hitting, thus obtaining a sophisticated product.
