Description

Technical Field

[0002] Steel pipe chamfering refers to beveling the edge or end of a steel pipe at a certain angle to make its edge or end smoother. This process is also called steel pipe chamfering or net head chamfering. It is usually automated by machine, but can also be done manually or by semi-automatic machines. Steel pipe chamfering is an important processing technology that can not only improve the appearance of the steel pipe and increase its aesthetics, but also reduce the contact area, thereby reducing abrasions and wear, and improving the safety and service life of the pipe fittings.

Referring to a steel pipe chamfering processing device disclosed in a patent application with reference to publication number CN218776279U, the steel pipe chamfering processing device places the steel pipe between two side plates during chamfering. The fixed block is moved by a moving assembly to move the steel pipes one by one into each fixed groove. When the steel pipe moves to the chamfering assembly, it is chamfered by the chamfering assembly. During chamfering, the previously chamfered steel pipe can be taken out, and a new steel pipe will fall into the next fixed groove, thereby realizing the continuous operation of loading, chamfering and unloading, thereby improving the chamfering efficiency.

[0004] However, the fixing device of the above-mentioned technology only relies on the friction of the baffle to fix the steel pipe, and this fixing method must ensure that the selection of the grinding wheel is perfectly matched with the material requirements of the steel pipe, which undoubtedly increases the complexity of operation and the difficulty of adjustment. It is inconvenient to use, and every time the chamfering angle of the steel pipe needs to be changed, the entire grinding wheel needs to be replaced, which reduces the working efficiency of the device and has general practicality.
