Description

Technical Field

[0001] This utility model relates to the field of stainless steel square tube technology, specifically a diagonal cutting device for stainless steel welded square tubes. Background Technology

[0002] Stainless steel square tubing is a hollow, long strip of steel, named for its square cross-section. It is widely used as a pipeline for transporting fluids such as oil, natural gas, water, coal gas, and steam. Furthermore, it is lighter in weight while maintaining the same bending and torsional strength, making it also widely used in the manufacture of mechanical parts and engineering structures.

[0003] In the processing of stainless steel pipes, diagonal cutting is a common and technically demanding operation. With the widespread application of stainless steel pipes in numerous industries such as building decoration, machinery manufacturing, and chemical equipment, the requirements for cutting quality and precision are becoming increasingly stringent.

[0004] Existing diagonal cutting devices for stainless steel pipes lack effective support measures during cutting. This leads to the stainless steel pipe, due to its length and weight, being prone to bending and deformation under the cutting force. Once the stainless steel pipe bends during cutting, it will not only seriously affect the cutting accuracy, but also prevent the cut pipe end from meeting the expected size and shape requirements, thus affecting subsequent processing and use. Therefore, a diagonal cutting device for stainless steel welded square pipes is proposed. Utility Model Content
