Adjustable special-shaped steel structure machining positioning die

By designing an adjustable positioning mold for irregular steel structure processing, the spacing between the inner and outer positioning modules is adjusted using an X-axis push-pull cylinder and a correction cylinder, and the inclined support and clamping positioning of the outer and inner plates are achieved through a telescopic cylinder. This solves the problem that the existing mold cannot adjust the support width, and improves the welding accuracy and operation efficiency of irregular steel structures.

AI Technical Summary

Technical Problem

Existing positioning molds for irregular steel structures cannot easily adjust the support width between the inner and outer positioning structures, making it difficult to accurately position irregular steel structures during welding.

Method used

An adjustable positioning mold for processing irregular steel structures was designed. The distance between the inner and outer positioning modules is adjusted by an X-axis push-pull cylinder and a correction cylinder. The outer and inner plates are supported and clamped by a telescopic cylinder. Combined with a magnetic buckle and slot structure, the mold can be flexibly adjusted.

Benefits of technology

It enables precise positioning and convenient movement of irregularly shaped steel structures, improves welding efficiency, and reduces operational difficulty and labor intensity.
