Abstract

The invention provides a square pipe twisting production line which comprises a necking device, a chamfering and drilling device and a twisting machine, wherein the twisting machine comprises a pair of twisting devices; the twisting devices comprise working platforms, and clamps and twisting mechanisms which are arranged on the working platforms; the twisting mechanisms are used for twisting a square pipe; the twisting mechanisms in the pair of twisting devices are arranged oppositely; mandrels inserted into the square pipe are arranged on the pair of twisting devices and are driven by a driving device to move into the square pipe. The square pipe twisting production line is precise in structure; equipment is matched with digital control; a servo motor and a stepping motor are used as an execution element, and hydraulic pressure is used as clamping power equipment to neck and twist the square pipe; the equipment is wide in application range; processed products are switched automatically by the equipment, and the equipment is high in flexibility and high in automation degree.

Description

technical field [0001] The invention relates to a square tube twisting production line. Background technique [0002] In the existing square tube forming process, processes such as shrinking, chamfering, drilling, and twisting are required, while the existing processes of the square tube basically use manual handling of the square tube and passing the square tube through multiple stages. The punching of the die will form shrinkage, chamfering, drilling, twisting and other processes. This method is inefficient and the quality is uneven, and the effect is not good, and it is easy to cause employee injuries. Contents of the invention [0003] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is that the square tube is formed by manual operation, and the efficiency is low. [0004] The specific embodiment of the present invention is: a square tube twisting production line, including a shrinking device, a ch...
