[0034] In this solution, when it is necessary to feed the tube material by rotating the feeding assembly, the first clamp driving device drives the first slider to slide along the first clamp sliding groove to the side away from the feeding port, and the second clamp driving device drives the second slider to slide along the second clamp sliding groove to the side away from the feeding port. The first slider slides through the first connecting block to drive the first roller to move, and the second slider slides through the second connecting block to drive the second roller to move, so that the two first rollers and the two second rollers are moved apart, so that the tube material can pass through the feeding port. After the tube material passes through the feeding port, the first clamp driving device and the second clamp driving device respectively drive the first slider and the second slider to slide in the opposite direction, so that the two first rollers and the two second rollers are close to each other. The pipe material is pressed against the pipe material, and the pipe material is pushed by an external device to continue to move in the feed pipe until it extends out of the rear clamp disk through the discharge circular opening. The hydraulic chuck on the rear clamp disk clamps the pipe material to make it in a horizontal state.

The output end of the clamp driving device drives the right clamp plate to move to the right through the second slide rail. When the right clamp plate moves, it drives the rack to move. The rack at the right clamp plate drives the gear to rotate so that the gear drives the rack at the left clamp plate to move, so that the left clamp plate moves to the left through the corresponding second slide rail. At this time, the clamping module is opened, and the left and right clamp plates can clamp the outer wall of the pipe material.

[0035] When it is necessary to clamp the pipe, the output end of the clamping plate driving device drives the right clamping plate to move to the left through the second slide rail, so that the right clamping plate drives the left clamping plate to move closer to each other to clamp the pipe. After the clamping module clamps the pipe, the hydraulic chuck releases the pipe, and the cutting platform slides backward on the first guide rail through the platform driving device. The sliding distance of the cutting platform is the cutting distance of the pipe. When the pipe slides, it drives the two first rollers and the two second rollers to slide. After the cutting platform finishes sliding, the hydraulic chuck re-clamps the pipe, and the clamping module releases the pipe. Then, the laser cutting device is moved to the cutting point through the lifting assembly and the displacement assembly to cut the pipe. When the pipe is cut, the feed pipe driving assembly drives the feed pipe to rotate, so that the hydraulic chuck, the first clamp mechanism and the second clamp mechanism drive the pipe to rotate, so that the pipe is cut by the laser cutting device.

[0036] The cut tube material rolls down through the inclined surface located at the lower rear side of the rotating feeding assembly, and a storage opening is provided on the inclined surface. When the tube material rolls down, it falls into the accommodating cavity through the storage opening, and then falls into the storage box for storage through the two second storage plates and the bottom of the two first storage plates to form a tube material storage opening.
