Problems solved by technology

[0002] In the field of bicycle processing, the diameter of the purchased pipes usually does not match the actual needs. For changing the diameter of the established pipes, most of the expansion equipment in the prior art can expand the diameter of steel pipes of various shapes, thereby As a result, this type of equipment has a complex structure and high procurement costs, but lacks a specific L-shaped steel pipe expansion equipment with simple structure, strong pertinence, and high processing efficiency.

Abstract

The invention discloses pipe expansion equipment which comprises a workbench and is characterized in that a steel pipe positioning clamping device, a pipe expansion device and a steel pipe jacking device are arranged on the workbench. The pipe expansion equipment has the benefits as follows: the pipe expansion equipment which is simple in structure, highly targeted and high in processing efficiency is provided for specific L-shaped steel pipes, and the production cost of an enterprise can be reduced greatly.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a pipe expansion device. Background technique [0002] In the field of bicycle processing, the diameter of the purchased pipes usually does not match the actual needs. For changing the diameter of the established pipes, most of the expansion equipment in the prior art can expand the diameter of steel pipes of various shapes, thereby This type of equipment has a complex structure and high purchase cost, but lacks a tube expansion equipment with a simple structure, strong pertinence, and high processing efficiency for a specific L-shaped steel pipe. Contents of the invention [0003] In view of the above, the present invention provides a tube expansion device with simple structure, strong pertinence and high processing efficiency. [0004] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problems i...
