Forming device for space bending pipe

Abstract

The invention discloses a forming device for a space bending pipe. The forming device for the space bending pipe comprises a base, two first clamps, a second clamp and a plurality of cutting tools, wherein two first guide units are arranged on the base; the two first clamps can move along the two first guide units respectively, locking devices are further arranged on the first clamps, and the locking devices can lock the first clamps on the base; the second clamp is arranged between the two first clamps, and the second clamp can be fixed on the base; and the first clamps and the second clamp can clamp a pipe fitting, and the cutting tool can cut off the pipe fitting between the first clamps and the second clamp. The forming device for the space bending pipe has the beneficial effects thatthe two first clamps can move along the first guide units respectively, so that the space bending pipe can realize an asymmetric structure; and the cutting tool can cut off the pipe fitting between the second clamp and the two first clamps, so that the two ends of the pipe fitting can be cut off at one time, and the machining efficiency of space bending pipe forming is improved favorably. The invention relates to the forming device for the pipe fitting.

Description

technical field [0001] The invention relates to a pipe fitting forming device, in particular to a space elbow forming device. Background technique [0002] A space bend refers to a pipe that bends in three-dimensional space. The bending of the space elbow is relatively complicated, and usually requires special fixtures and molds to realize the forming. [0003] The tube forming process usually includes bending, scoring and cutting. The bending process entails bending the tube into the desired shape. The scribing process needs to draw a preset cutting track on the pipe. The cutting process needs to fix the pipe, and then use the cutting tool to cut along the scribed track. [0004] The evaporator is a common tool for medium heat exchange. In the evaporator, multiple tubes need to be arranged side by side, and the end surfaces at both ends of each tube need to be in the same plane. [0005] In the prior art, in order to obtain a space elbow whose end faces at both ends c...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, in order to obtain a space elbow whose end faces at both ends can be coplanar, it is necessary to strictly control the machining accuracy of the pipe fittings during the marking and cutting process. The technical defect lies in: the bending process, marking process and cutting process of the space elbow. The continuous degree of the process is low, so that the processing efficiency of the space bend is not high
