AI Technical Summary

Technical Problem

Existing cold bending technology for metal pipes requires highly skilled operators, and the separate measurement and operation of length and curvature control are cumbersome, limiting the efficiency of small-batch, multi-specification processing.

Method used

A cold bending processing device for metal pipe fittings was designed. It adopts a first limiting member that can move linearly and a second limiting member that can move in an arc. By presetting the position of the limiting member, one-time forming can be achieved, reducing skill requirements and adapting to the processing of workpieces of different specifications.

Benefits of technology

It enables one-time forming without measurement, reduces the skill requirements for operators, improves work efficiency, and is especially suitable for multi-specification small-batch cold bending processing, ensuring processing quality.

Abstract

The invention discloses a metal pipe fitting cold bending machining device which comprises an operation table, a pipe bending base and a rotating base are arranged on the surface of the operation table, the rotating base can directionally rotate around the pipe bending base, the rotating plane of the rotating base is parallel to the surface of the operation table, and scale marks are correspondingly arranged on the rotating base and the pipe bending base. A first containing groove and a second containing groove are correspondingly formed in the side faces close to each other, the first containing groove extends in the arc direction, the second containing groove extends in the linear direction, and a workpiece fixing block is hinged to the portion, on the outer side of the first containing groove, of the pipe bending base. In the rotating direction of the rotating seat, the rotating seat and the pipe bending seat have corresponding initial zero positions, and the scale marks on the pipe bending seat are distributed in a progressive increase or progressive decrease mode in the bending direction of the first containing groove; the operation table is provided with the first limiting piece capable of directionally moving linearly and the second limiting piece capable of directionally moving in an arc line, the length and the bending arc length of the workpiece are limited respectively, measurement is not needed when the workpiece is subjected to cold bending machining, one-time forming is achieved, and the skill requirement can be effectively lowered.
