Novel pipe bending machine

Abstract

The invention provides a novel tube bending machine, and relates to the field of tube bending machines. The novel tube bending machine comprises a working table, wherein a machine groove is formed inthe surface of the working table, a hydraulic machine is fixedly connected to the inner wall of the machine groove, a bent tube tapping die is hinged to the output end of the hydraulic machine, an arc-shaped bent tube swing groove is formed in the lower surface of the bent tube tapping die, a bent tube extrusion plate is arranged on the inner wall of the arc-shaped bent tube swing groove, a plurality of first clamping grooves are formed in the surface of the bent tube extrusion plate, a plurality of second clamping grooves are formed in the inner wall of the arc-shaped bent tube swing groove,and first connecting balls are rotationally connected to the inner walls of the first clamping grooves. Compared with traditional damping, the novel tube bending machine has the advantages that swingcaused by the tube bending machine is utilized, the tube bending machine is made to swing regularly, the contact surface is increased, and the cutting force is reduced, so that the problems that due to the fact that a common pipeline bending machine is prone to generate small-amplitude swing when the bending torque is large, the contact surface between a pipeline and a mold is prone to cut each other and to be damaged in the swinging process, and then waste of resources is caused, and meanwhile, the working progress can be influenced are effectively solved.

Description

technical field [0001] The invention relates to the technical field of pipe bending machines, in particular to a novel pipe bending machine. Background technique [0002] The pipe bender is a machine used to bend metal pipes. The current pipe bender will still be affected by the design blind spot of the machine when it is used. The material and thickness of the pipe directly determine whether the pipe bender can complete the pipe bending work. The molds used in commonly used pipe bending machines are often aimed at carbon steel pipes. For the bending of alloy steel pipes and stainless steel pipes, due to the different characteristics of the materials and the lack of corresponding related technologies, it is often impossible to obtain the ideal bending section deformation rate and bending angle. For pipe benders with large torque, due to the blind area of ​​the design, it is easy to cause static instability and instability problems, and this instability is irregular and the s...
