Description

Technical Field

[0001] This utility model relates to the field of pipe processing, specifically to a pipe beveling and grinding equipment. Background Technology

[0002] Setting and grinding the bevel at the pipe end is a crucial step in the welding process. Grinding removes burrs from the bevel and ensures its cleanliness, improving subsequent welding results. For example, Chinese patent CN220481188U provides a pipe welding bevel grinding device, including a frame composed of a bottom beam and support rods symmetrically arranged at both ends of the bottom beam. The bottom beam is located in the middle of the beam and connected to a sliding frame via an auxiliary connecting block. The support rods have grooves along their axial direction, and springs are sleeved on the outer circumference of the rods below the I-shaped slider.
