Technical Field

[0001] The utility model relates to the field of machining, in particular to a bending device for metal pipes. Background Art

[0002] A water supply pipe structural component used in industrial production is made of metal and consists of four metal tubes of varying lengths. During the product manufacturing process, the complete set arrives at the final assembly workshop unfinished, requiring final assemblers to bend the copper tubes and adapt them to the product's assembly requirements. During the initial production and assembly phase, bending issues in the water supply pipe significantly impacted the overall assembly progress and quality.

[0003] Specifically, there are the following problems:

[0004] 1. The water pipe is made of copper and needs to be bent into shape once. Repeated bending will cause cracking, which will cause test failure in subsequent water pressure and air tightness tests.
