Description

Technical Field

[0001] This invention relates to the field of steel pipe production technology, specifically to a steel pipe chamfering device and method. Background Technology

[0002] Beveling steel pipes is a key process before welding and assembly. It aims to eliminate burrs at the pipe ends, optimize the bevel angle, and ensure welding strength and sealing. Clamping devices are required during the beveling process.

When different types of steel pipes need to be processed, different types of clamping devices need to be replaced to adapt to the steel pipes, which takes a lot of time. Secondly, the clamping blocks of existing clamping devices are mostly metal-hard contact structures. During the clamping process, the clamping blocks may damage the steel pipe, and with prolonged use, the clamping blocks themselves will also be damaged. Summary of the Invention

Since the thread direction of the thread a104 is different, the clamping arms 105 turn in opposite directions and will self-lock on the limiting rod a106, so that the clamping arms 105 can only slide along the limiting rod a106. 2: The electric push rod a201 pulls the clamping block 202 closer. When the arc-shaped clamping plate 205 contacts the steel pipe, the damping spring shock absorber 206 retracts, and the slide rod 204 slides in the slide groove 203 to prevent the damping spring shock absorber 206 from deflecting and to buffer the pressure at the time of contact.
