Abstract

A way controlling automatic centering perforating for seamless tube blank puncher sets the drilling action parameter, PLC sends out order after computing the data received through communication cable, fine controlling the forward and backward of the cart running on the track, with the robot moving to finish the actions like centering, inducing contacting and arcing till the completion of the centering drilling of holes. It is exact in controlling, accurate in centering, high in quality with quick drilling speed. It improves the quality of seamless tube with reduced rolling cost.

Description

Technical field: [0001] The invention relates to a method for controlling the online automatic centering punching of a seamless tube billet punching machine. Background technique: [0002] In the production of seamless pipe from blank to rough tube, the piercing process requires head-to-tail centering of the blank to solve problems such as product quality and yield, that is, to punch a process hole at the center of the end of the seamless tube blank . There are several traditional solutions as follows, but all of them have insurmountable defects. [0003] The first heat centering method [0004] The tube blank heated by the heating furnace is sent to the centering station at the head and tail by the conveying roller table, and returns to the front of the punching machine for punching through the centering machine. This method solves the need for centering the tube blank, but loses the temperature of the tube blank, which brings difficulties in the process of biting the pi...
