Description

Technical Field

[0001] The utility model relates to the field of hook tail frames, in particular to a bending device for processing railway train hook tail frames. Background Art

[0002] The railway train hook tail frame is a key component connecting vehicles. It needs to undergo a series of processing steps during the manufacturing process, including bending. The bending device is used to bend materials such as steel or aluminum alloy into the required shape to meet the design requirements of the hook tail frame. They can effectively process metal materials into the required hook tail frame shape to ensure the safety and reliability of railway transportation.

[0003] However, most of the bending devices used for railway train hook tail frame processing have the following problems:

[0004] For example, a hook tail frame bending device with publication number CN202121373258.8 is convenient for stamping and forming, but it can only process materials of a certain width during processing. If the material width is small, it is easy to cause shaking and offset during processing. If the material is tilted during processing, quality problems are likely to occur, and it is inconvenient to perform limited processing on materials of different widths; at the same time, when using a pressure head for stamping, the pressure head is mostly connected to the stamping equipment by fixing or welding. It is more troublesome to replace pressure heads of different sizes, and the pressure head is prone to damage after long-term use. Subsequent replacement and disassembly require removal of multiple bolts, etc., which makes disassembly more troublesome and inconvenient for convenient disassembly and installation.

[0005] Therefore, we make improvements on this and propose a bending device for processing the railway train hook tail frame. Utility Model Content
