一、拉削在连杆加工中的应用 随着科学技术的发展,于六十年代末期出现了连续拉床,即人们习惯叫的“坦克拉”。连续拉床与一般拉床不同。一般拉床上的拉刀是安装在一个沉重的滑枕上,在完成一次拉削后,必须等待滑枕返回原位之后,才能开始下一个循环。而连续拉床,则是拉刀装在连续运转的双链条之间的固定框架上。在链轮驱动的环形链条上有一个总是单向移动的和行程无限长的随行夹具。这样,至少在理论上,它是连续运转的。当随行夹具运行到机床上面时,即可装料。工件在夹具上的夹紧和松开,通常都是自动的。拉削好的工件落到输送带上,由输送带将其送出拉床。
First, broaching in the link processing application With the development of science and technology, appeared in the late sixties continuous broaching, that is, people used to call the “tank pull.” Continuous broaching and general broaching different. General broaching broach is mounted on a heavy ram, after a broach, you have to wait for the ram to return to its original position, to start the next cycle. The continuous broaching machine, the broach is mounted on the continuous operation of the double chain between the fixed frame. On the sprocket-driven endless chain there is always a one-way travel with unlimited travel. In this way, at least in theory, it runs continuously. When the accompanying fixtures run to the top of the machine, you can charge. Clamping and loosening of the workpiece on the fixture is usually automatic. Broaching a good workpiece fell on the conveyor belt, the conveyor belt will be sent out of the broaching machine.
