Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machine accessories, in particular to a pipe bending device for a pipe bending machine. Background Art

[0002] Pipe bending machine refers to a machine used for bending pipes and can also be used as a jack. It is roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is used in power construction, road and railway construction, bridges, ships and other aspects of pipeline laying and repair. Pipe bending machine can be roughly divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. It is mainly used for power construction, railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure and simple operation.

[0003] In the bending process of the pipe bender, the pipe bending assembly is a relatively important component. The traditional pipe bending assembly bends due to physical properties, which will cause stress difference between the inside and outside of the bending component pipe. If a stress relief step is added to the pipe with a smaller curvature, the production cost will increase and the efficiency will be low. The existing pipe bending machine bending assemblies do not have stress relief function. Based on this, we propose a pipe bending device for a pipe bender. Utility Model Content

The first electromagnetic heating plate 2 is installed on the top of the mounting plate 1, and a transmission gear disc 11 is fixedly installed on the bottom of the mounting plate 1. A pillar 12 is fixedly installed on the bottom of the mounting plate 1, and a shaft seat 13 is movably sleeved on the outer side of the bottom end of the pillar 12, and a fixed plate 14 is fixedly installed on the bottom of the shaft seat 13.

[0020] The working principle of the above technical solution is as follows: when in use, the mounting plate 1 is mounted at a fixed position of the pipe bending machine through the fixing plate 14 and the shaft seat 13, and then the power transmission mechanism is connected through the transmission gear plate 11, and then the first slide 6 is slid to the position of the first slide groove 5 according to the bending operation requirements, and after reaching the required position, the bolt is passed through the hollow threaded column 21 and extended to the inside of the threaded hole 23 to fix the position of the pipe bending roller 4.

The existing technology is directly adopted and installed flexibly. This scheme is only for displaying the position and use to achieve the purpose of electromagnetic heating and facilitate coordinated operation. There are many structural properties of electromagnetic heating, so it can be changed according to actual needs.

[0025] In another embodiment, Figure 1-Figure 4 As shown, the rotating plate 9 is rotatably installed on the top of the arc-shaped slider 24 through the rotating shaft passing through the arc-shaped slider 24.
