본 고안은 고정다이와 직선 왕복운동하는 이동다이 사이로 가공물을 통과시켜 볼트, 나사등의 나사산을 가공하는 평형의 롤링머신을 구성함에 있어서 크랭크간으로 부터 전달되는 힘을 이동다이가 설치된 왕복대에 거의 수평으로 무리없이 작용되게 하므로서 왕복대와 다이의 수명을 길게하고 가공물의 나사산 각도와 피치를 일정하면서도 보다 정밀하고 깨끗하게 가공할수 있도록 한 고안에 관한 것이다.The invention devises a flat rolling machine that passes through the workpiece between the fixed die and the linear reciprocating moving die to process the threads of bolts, screws, etc., so that the force transmitted from between the cranks is almost horizontal to the carriage installed with the moving die. The present invention relates to a device designed to prolong the life of the carriage and the die and to process the thread angle and the pitch of the workpiece more precisely and cleanly.
종래의 평형다이를 사용하는 롤링머신은 제4도에서와 같이 이동다이가 설치된 왕복대(4) 후미를 그 후미 상측에 설치된 종동기어(2a)의 크랭크간(3a)에 곧바로 연설하여 된 구성으로서 이는 크랭크간이 강력한 힘으로 왕복대의 후미를 상측에서 아래로 내리눌르면서 동력을 전달하도록 되었기 때문에 그 충격에 의해 궤도면(11)에 올려진 상태에서 슬라이드되며 직선운동 하는 왕복대의 후미 밑부분이 쉽게 마모가 되었고, 이와같이 후미 밑부분이 점차 마모되면 직선운동 하는 왕복대의 흔들림이 점차 심하여져 왕복대의 직선운동이 불안정하게 됨에따라 가공물의 나사산 가공상태가 지저분하고, 특히 나사산의 각도와 피치가 점차 상이하게 가공되기 때문에 불량률이 높은 반면에 이를 가공하는 고가품의 다이 수명이 짧게되는 폐단이 있었다.The rolling machine using the conventional balancing die is a configuration in which the rear end of the carriage 4 on which the moving die is installed is directly addressed to the crank section 3a of the driven gear 2a provided above the rear end as shown in FIG. This is because the crankshaft is designed to transmit power by pushing down the rear end of the carriage with a strong force from the upper side and slides on the track surface 11 due to the impact, and the bottom of the rear end of the linear carriage moves easily. As the bottom part of the tail is gradually worn out, the shaking of the linear shuttle moves gradually, and as the linear movement of the shuttle becomes unstable, the thread processing state of the workpiece is messy, especially the thread angle and pitch are gradually changed. As a result, the defect rate was high, while the die life of the expensive products for processing them was shortened.
본 고안은 이와같은 점을 감안하여 창안된 것으로서 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention was created in view of the above, and described in detail by the accompanying drawings as follows.
이동다이(5)가 설치된 왕복대(4)를 궤도면(11) 위에서 슬라이드 되게 설치하여 직선 왕복운동 하도록 된 것에 있어서 크랭크간(3)이 유설된 종동기어(2)를 왕복대(4) 하부의 본체(1) 내에 축설하고 왕복대(4) 후미에는 신축조절되는 로드(6)를 핀(7)으로 연설한 다음 로드(6)와 크랭크간(3) 사이에 레버(8)를 핀(9)(10)으로 연설하되 핀(7)(9)과 왕복대(4)의 중심이 거의 일직선상이 되게 연설하여 된 것으로서 도면중 미설명 부호(12)는 주동기어이고 (13)은 고정다이 이며 (2a)(3a)는 종래 롤링머신의 종동 기어와 크랭크간이다.In the case where the carriage 4 on which the moving die 5 is installed is slid over the raceway surface 11 so as to reciprocate linearly, the driven gear 2 in which the crank shaft 3 is installed is moved to the lower portion of the carriage 4. In the main body 1 of the main body 1, and at the rear of the carriage 4, the retractable rod 6 is extended to the pin 7, and then the lever 8 is pinned between the rod 6 and the crankshaft 3; 9) (10), but the centers of the pins (7) (9) and the carriage (4) are almost in a straight line. In the drawing, reference numeral 12 is the main gear and 13 is the fixed die. And (2a) and (3a) are between the driven gear and the crank of the conventional rolling machine.
이와같이 형성된 본 고안은 주동기어(12)로부터 동력을 전달받은 종동기어(2)가 본체(1)내에 설치되므로서 기계의 크기를 상당히 줄일수 있는 것으로서 종동기어(2)가 회전되면 크랭크간(3)의 작동에 의해 크랭크간(3)에 일단이 연설된 레버(8)가 전후 왕복 운동을 하게되며 이에따라 레버(8)와 로드(6)로 연설된 왕복대(4)가 직선 왕복운동을 하게되는 것이다.The present invention formed as described above can significantly reduce the size of the machine since the driven gear (2), which receives power from the main gear (12), is installed in the main body (1). By the operation of the crank shaft 3, the lever 8, one end of which is pushed forward and backward, is reciprocated. Therefore, the carriage 8, which is pushed to the lever 8 and the rod 6, performs a linear reciprocating motion. Will be.
이때 본 고안은 레버(8) 상단의 로드(6)를 접속하고 있는 핀(9)의 중심이 왕복대(4)의 중심 및 로드(6)를 접속하고 있는 핀(7)의 중심과 거의 일직선 상태를 유지하면서 레버(8)가 작동되기 때문에 제2a, b도에서와 같이 왕복대(4)는 궤도면(11)을 따라 충격이 별로없이 보다 원활하게 왕복운동을 하게된다.In this case, the center of the pin 9 connecting the rod 6 on the upper end of the lever 8 is almost in line with the center of the carriage 4 and the center of the pin 7 connecting the rod 6. Since the lever 8 is operated while maintaining the state, as shown in FIGS. 2A and 2B, the carriage 4 smoothly reciprocates smoothly with little impact along the raceway surface 11.
그러므로 본 고안은 이동다이(5)가 설치된 왕복대(4)가 왕복 운동을 함에 있어서 충격을 별로 받지 않으면서도 전혀 무리가 없이 작동되기 때문에 장기간을 가동 하드라도 종래와 같이 왕복대(4)의 후미 밑부분이 마모되어 유동될 우려가 없음에 따라 왕복대가 지속적으로 정밀하게 직선운동 할수 있으므로 이동다이(5)에 의해 가공되는 나사산의 각도 및 피치가 일정하면서도 보다 깨끗하고 정밀하게 가공될수 있으며 이에따라 상품가치는 더욱 향상되고, 불량률은 최대한 줄일수 있어 대외 경쟁력이 매우 우수하면서도 고가품인 다이의 수명을 상당히 연장할수 있는 경제적 이익과 기계가동시 소음을 상당히 줄일수 있어 작업환경을 개선할수 있는등의 효과가 있는 것이다.Therefore, the present invention is the rear end of the carriage 4 as in the prior art even if the long-term operation is hard because the operation of the carriage 4 is installed without any impact in the reciprocating movement without any impact in the reciprocating motion. Since there is no fear of the bottom part being worn and moving, the carriage can be continuously and precisely linearly moved, so the angle and pitch of the thread processed by the moving die 5 can be processed more consistently and cleaner and more precisely. Is further improved, and the defect rate can be reduced as much as possible, so that the external competitiveness is very good, and the economic benefits that can significantly extend the life of expensive dies and the noise during machine operation can be significantly reduced can improve the working environment. will be.
