Abstract

The invention provides a pipe bending device. The pipe bending device comprises a working table and a fixing base and a pipe bending assembly, wherein the fixing base and the pipe bending assembly are fixedly arranged on the working table. The pipe bending assembly comprises a U-type connecting member arranged transversely, a first idler wheel and a second idler wheel, wherein the first idler wheel and the second idler wheel are horizontally arranged in an inner cavity of the U-type connecting member, and a gap allowing a steel pipe to be bent to penetrate is formed between the first idler wheel and the second idler wheel. One end of a handle penetrates through a base plate of the U-type connecting member and is inserted into and abuts against the outer surface of the first idler wheel, a zigzag type reinforcing plate is arranged at the tail end of the U-type connecting member, a first pin shaft penetrates through the U-type connecting member and the first idler wheel from top to bottom in sequence and then is fixed by a first nut, and a second pin shaft penetrates through the reinforcing plate, the U-type connecting member, the second idler wheel and the working table from top to bottom in sequence and then is fixed by a second nut. The pipe bending device is reasonable in structure, firm, practical, simple in operation and capable of conducting on-site actual matching of bending shapes of different angles on thin-wall stainless steel pipes, the material characteristics of the thin-wall stainless steel pipes are not damaged, and using performance of the thin-wall stainless steel pipes is enhanced.

Description

technical field [0001] The invention relates to a device for bending and forming metal pipes, in particular to a pipe bender. Background technique [0002] In the automotive industry, it is often necessary to bend metal pipes into workpieces with certain curvature, angle and shape. At present, the traditional process of pipe bending is sand filling, scribing, heating, and bending. After heating, the plasticity of the material increases, and the force required for bending is small. The outer layer of the pipe is stretched and becomes longer, and the inner layer is compressed and shortened. However, after heating, the material is easy to oxidize, decarburize, overheat, burn, melt, and the working conditions are poor. For thin-walled stainless steel pipes, this bending forming method is likely to cause serious wrinkles and cracks in the bending parts. Contents of the invention [0003] The present invention is completed in order to solve the deficiencies in the prior art. ...
