Description

A stainless steel pipe straightening device

Technical Field

The utility model relates to the technical field of stainless steel pipe processing, in particular to a stainless steel pipe straightening device.

Background Art

Stainless steel pipe is a hollow long round steel. The main materials of stainless steel pipe are austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, duplex stainless steel and precipitation hardening stainless steel. It is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils. During the processing of stainless steel pipes, they need to be straightened.

At present, when straightening stainless steel pipes, the stainless steel pipes are first placed on a placement rack, and the straightening blocks are driven downward by a lifting assembly to squeeze and straighten the stainless steel pipes. However, the spacing between the two placement racks is generally fixed and cannot be adjusted, resulting in that only stainless steel pipes of specific sizes can be straightened during straightening, which has certain limitations and poor applicability.
