Working Theory

The tube is rolled by the main working frame, which move forward and backward, powered by the main motor through belt wheel, gearbox, and mechanical connection bar. In the same time, the power is also applied to the feed-rotate box through a cone-type gearbox, causing the tube interval rotation, realize the rolling process.

The circular groove of roller used in the mill features long working stroke, compact structure. The cone-type of pass keeps according with the cone-type mandrel during rolling, which result the pass gradually reduced when the roller move forward, the tube is rolled and reeled continuously. On the revised process (backward of the roller), the gorge gradually enlarged, the tube is reeled again. A complete stroke accomplished after the roller move forward and backward, the tube is fed forward and rotates a certain degree ready for the next stroke. By repeat rolling (stroke) again and again until the finished tube achieved.

Above drawing shows the theory of LG20 cold pilger mill working process. The pass (section) is gradually reduced when roller moves from point A to B (forward stroke), both the OD and WT of tube are reduced. The pass (section) increased when the roller move from point B to A (backward stroke), and the tube is rolled and reeled again. When tube comes to the point where the gorge section bigger than the tube section, the tube rotates a certain degree by a mechanical system located at the rear end of the mill. By repeating this process, a finished tube is achieved.
