Pipe bender

Abstract

The invention discloses a pipe bender. According to the pipe bender, the angle of force applying handles can be conveniently and rapidly adjusted in the pipe bending process, so that more labor is saved when a pipe is bent, and the technical problems that when the pipe is bent from 90 degrees to 180 degrees in the prior art, force is applied difficultly by an operator due to the fact that the two handles are close to each other continuously, and the pipe bending efficiency and quality are seriously affected are solved. The pipe bender comprises the fixed handle and a pipe bending disc arranged at one end of the fixed handle. A pipe press head capable of clamping a copper pipe and rotating along the annular face of the pipe bending disc is rotationally connected to the pipe bending disc. The pipe press head is rotationally connected to the inner side end of the pipe press handle through a long arc-shaped hole and a rotary shaft penetrating into the long arc-shaped hole in a sliding mode. The outer side end of the pipe press handle extends outside the pipe press head corresponding to the upper portion of the fixed handle. A front press rotary pin and a rear press rotary pin are arranged side by side at the portion, close to the long arc-shaped hole, of the pipe press head. The pipe press handle horizontally abuts against the front press rotary pin or the rear press rotary pin or perpendicularly penetrates through the portion between the front press rotary pin and the rear press rotary pin to drive the pipe press head to rotate along the outer ring face of the pipe bending disc.

Description

technical field [0001] The invention relates to a pipe bender, in particular to a pipe bender which can conveniently and quickly adjust the angle of a force-applying handle during the pipe bending process to make pipe bending easier and labor-saving. Background technique [0002] Metal pipes such as stainless steel pipes and copper pipes often need to be bent during use to change the original straight flow direction, and the pipe bender is a special tool for bending metal pipes. Existing lever-type pipe benders generally use the principle of leverage to drive the pressure head to force the metal pipe to deform according to a specified arc to obtain a bent metal pipe. However, during the pipe bending process, especially when bending from 90 degrees to 180 degrees, since the two handles are constantly approaching at this time, it is difficult for the operator to apply force, which is time-consuming and laborious, which seriously affects the efficiency and quality of pipe bendi...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly provides a pipe bender that can conveniently and quickly adjust the angle of the force-applying handle during the pipe bending process, making the pipe bending process easier and labor-saving, and solves the problem of bending from 90 degrees to 180 degrees in the prior art. When processing high-degree bending pipes, it is difficult for the operator to apply force due to the continuous approach of the two handles, which seriously affects the efficiency and quality of pipe bending processing and other technical problems.
