Background

In the process of processing the seamless steel tube, cold drawing processing is often used. The hot-rolled steel pipe is formed by processing and hardening the pretreated hot-rolled steel pipe to generate plastic deformation through a die with a certain shape and size under the action of drawing force by adopting a hydraulic high-precision cold-drawing machine.

The steel pipe of drawing of steel pipe generally can use steel pipe drawing drive arrangement, however, what current steel pipe drawing drive arrangement generally adopted is that chain and motor are as drive arrangement, and steel pipe anchor clamps are as fixture, and support or walking dolly are installed at the top of chain, through motor drive chain to realize drawing of steel pipe, however, because the steel pipe that some users that have now required draws dimensional accuracy is higher, adopt this kind of drive mode to be difficult to satisfy user wide's demand, the reason lies in: when the motor drives the chain to operate, and simultaneously, after the steel pipe drawing required size is determined, during operation, after the support or the walking trolley draws the steel pipe to an accurate drawing position, the motor stops and the drawing operation is finished, however, in the stopping process of the motor, a buffer stage (continuous rotation) still exists on a rotating shaft on the motor, the chain can continuously drive the support or the walking trolley to move due to inertia, the drawing size of the steel pipe has deviation, and therefore some steel pipes with high precision requirements cannot be met, in addition, in the drawing process, because the weight of the steel pipe is large, when the steel pipe is clamped by the steel pipe clamp to be drawn, the steel pipe can fall off due to overlarge drawing force, once the steel pipe falls off, a large potential safety hazard exists, and even if the steel pipe does not fall off from the clamp, the situation that the drawing quality is reduced due to unstable steel pipe clamp clamping of the steel pipe can also occur, eventually leading to a reduction in the quality of the product.
