Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a stainless steel pipe bending device. Background Technology

[0002] Stainless steel pipe bending equipment is a specialized device used to bend stainless steel pipes. It mainly uses mechanical force or hydraulic drive to cause the stainless steel pipe to undergo plastic deformation under the action of a mold, thereby forming a bend with a specific curvature radius.

[0003] Mechanical manual stainless steel pipe bending devices rely on multiple bending wheels working together to bend the pipe. The bending wheels are arranged in fixed positions, and a mechanical structure ensures stable stress points during bending, preventing pipe displacement and deformation. However, the fixed wheel design has significant limitations, only suitable for a small number of stainless steel pipe models with simple parameters such as diameter and wall thickness. Even with a detachable structure, actual operation still requires tools to disassemble components such as the wheel positioning device and mold slots, making the disassembly and assembly process complex and time-consuming. Furthermore, installation accuracy may affect the bending quality, making it difficult to meet diverse processing needs. In processing multiple pipe specifications, operational efficiency and flexibility are limited. Utility Model Content
