Clamp assembly for pipe processing machine

The present invention relates to a clamp assembly for a device for processing a tubular member.

The prior art pipe processing machine includes a main body power source, a clamp power source, a transmission component and a clamp assembly. The clamp power source transmits the plurality of clamps of the clamp assembly to move radially inward or outward through the transmission assembly. Squeezing the pipe to be processed, the main power source rotates the entire clamp assembly through the transmission assembly, and then the clamp of the extruded pipe member moves around the pipe member to reduce the overall outer diameter of the pipe member;
