The development of the welding positioner in the machine tool industry has evolved with the development of the welding structure of machine tools. The leading products of China's machine tool industry mainly include metal cutting machine tools, forging machinery products, foundry machinery products, woodworking machine tools, tool products, abrasive tools and machine tool accessories. Among them, metal cutting machine tools, forging machinery and casting welding positioner products are the main fields of machine tool industry positioner applications.
The welding positioner has also gradually developed into the leading technology of the machine tool industry, which is mainly reflected in the following aspects:
(1) Some key enterprises have established welding workshops or metal structure factories with a certain scale, and established a complete welding management system. Absorbed and digested the welding process standards of imported products, implemented national professional standards, and formulated corporate standards.
(2) Improve the welding process, from a single processing technology to a set of emerging comprehensive engineering technology from raw material pretreatment, cutting blanking, forming, welding, post-weld inspection and post-weld treatment.
(3) CNC precision cutting and computer programming nesting technology has been applied, and the traditional manual cutting and blanking has been changed, reducing the machining.
(4) The new vibration aging process has been promoted to achieve the purpose of reducing and homogenizing the residual stress of the welded structure, reducing the deformation of the welded parts and stabilizing the accuracy.
