A lifting module and a release module are also arranged on the pre-storage plate 73.

[0038] In this solution, multiple pipes are placed on a transmission component, which transmits all the pipes backwards until the single pipe at the last end contacts the first inclined surface on the front side of the pre-storage plate, and the lifting module lifts the single pipe at the last end upward along the first inclined surface. The single pipe at the last end is lifted along the first inclined surface and rolls down to the second inclined surface and is finally blocked by the release module.

After the pipe is centered, the support telescopic device drives the support base to rise, and lifts the pipe to the coaxial position of the feed port. The pushing platform in the pipe pushing mechanism is driven backward by the pushing platform driving device, driving the pushing joint to push the pipe backward until it passes through the feed port.

[0039] After a single pipe passes through the feed port, the first clamp driving device drives the first slide block to slide along the first clamp slide groove, and the second clamp driving device drives the second slide block to slide along the second clamp slide groove. The two first clamp mechanisms and the two second clamp mechanisms clamp the pipe, and then the first driving device drives the clamp disk to rotate so that the clamp disk drives the pipe to rotate. After the pipe rotates, the cutting platform drives the laser cutter to move to a preset position, and the cutting lifting assembly drives the laser cutter to descend, so that the laser cutter cuts the pipe.

[0040] Since some pipe materials are relatively soft, the longer the pipe is cut, the greater the deviation will be during cutting, and the larger the bevel will be at the cutting point. To avoid this situation, the support lifting device in the support assembly will lift the support seat, and the rise of the support seat will drive the support roller to rise synchronously. The support groove on the support roller can lift the lower half of the pipe to avoid deviation of the pipe.
