Technical Field

Background

The metal threaded pipe is a pipe body which can be connected with one section by one section. Theoretically, the device can be connected infinitely to represent that the device has infinite length, and the threaded pipe can climb over a high mountain and transport fresh blood continuously across a river. For its reliable connection, the stable pipe thread must be machined (preferably by a numerically controlled lathe) and a set of feeding aids must be required for how the metal pipe, having a length of more than 20 meters and a weight of more than 1000kG, is fed into the machine for machining and production.

However, most of the existing feeding auxiliary machines are manually operated, the steps are complicated, the efficiency is low, and the main problem is that a control console is needed for the operation of workers, and the control console is provided with control buttons for feeding, blanking, advancing, retreating, lifting, descending, fine adjustment, rotation and the like. The main cause of the above problem is constituted by an electromechanical drive control apparatus of an old-type auxiliary machine. If lifting requires hydraulic or pneumatic devices, the back and forth movement and rotation require alternating current motor drive. It can thus be seen that each electric gate button controls a power unit or an electric motor or hydraulic valve etc. Such operational behavior is difficult to control and the accuracy is achieved entirely by human control of the electric gate.
