Tube bending machine and clamping mechanism thereof

Abstract

The invention relates to a tube bending machine and a clamping mechanism thereof. The tube bending machine comprises: a heading mechanism installed on a bed piece along a metal tube transportation path, two boosting mechanisms, rotary structures and two clamping mechanisms, wherein when the metal tube is bent, the heading mechanism holds the metal tube and provides an axial driving force. One of the two clamping mechanisms protrudes under the metal pipe and clamps the metal tube from the side, and one of the two boosting mechanisms pushes against the metal tube. The clamping mechanism comprises: a side snap gauge, an elastic support rod and a boosting part. One side of the side snap gauge is hinged on the end part of the elastic support rod, and the other side thereof pushes against the boosting part. When the boosting part drives the side snap gauge and the elastic support rod to move toward the metal tube and the elastic support rod is blocked, the elastic support rod is elastically deformed along the axial direction, while the side snap gauge revolves around the end part of the elastic support rod under the impetus of the boosting part. The tube bending machine is capable of successively bending bilateral snake-like bends.

Description

Technical field [0001] The invention relates to a pipe bending device, in particular to a pipe bending machine for bending a double-sided serpentine pipe bending machine and a clamping mechanism thereof. Background technique [0002] In industry, it is often necessary to bend the metal pipe into a serpentine (or S-shaped) bend. Such as figure 1 Shown is a schematic diagram of a single R double-sided serpentine elbow. [0003] See figure 2 Shown is a schematic diagram of an existing pipe bender. The existing pipe bender 8 includes a revolving structure 81 and an upsetting assisting mechanism 82. Among them, the revolving structure 81 includes a revolving body 811; a bending die 812 provided on the revolving body 811; a side clamping tube mechanism 813 provided on one side of the bending die 812; wherein the top upsetting assist mechanism 82 includes a top upsetting mechanism 821 and booster 822. [0004] Such as figure 2 , image 3 Shown is a schematic diagram of a double-sided...

AI Technical Summary

Problems solved by technology

[0005] This shows that the above-mentioned existing pipe bender obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the problems of the pipe bending machine, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above problems, which is obvious. It is a problem that relevant industry players are eager to solve
