Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a clamping and fixing device for processing stainless steel pipes. Background Art

[0002] Medical stainless steel refers to the use of 18% chromium and 10% nickel to make it more durable and corrosion-resistant. It still leaks metal ions, which is generally harmless but should be avoided by people with nickel allergies. This type of stainless steel is called stainless steel. Due to its durable and safe nature, it is mainly used in the manufacture of medical devices. Stainless steel pipe is a hollow long round steel. When stainless steel pipe is produced and processed, it needs to be clamped and fixed.

[0003] Most of the existing medical stainless steel tube fixing and clamping devices adopt a single fixing method such as a bolt, which often requires frequent disassembly and clamping of the steel tubes when processing steel tubes of different sizes, making the operation steps very cumbersome and unable to clamp steel tubes of different calibers. For this reason, we propose a clamping and fixing device for stainless steel tube processing. Utility Model Content
