[0014] The present invention provides a metal product butt welding device, which has the following beneficial effects: (1) The invention installs the pipe into the pipe clamping device and the disc into the disc clamping device at the same time, and then starts the linear motor. The linear motor drives the rotating device to move toward the disc clamping device. The movement of the rotating device toward the disc clamping device drives the pipe clamping device to move toward the disc clamping device. The pipe and the disc are docked. Then the rotating motor and the welding device are started. The welding device welds the disc and the pipe together. During welding, the motor and the rotating device rotate synchronously to ensure that the disc and the pipe are completely installed together.

[0015] (2) In the present invention, the circular ring continuously moves and contacts the L-shaped plate, which pushes the circular ring toward the pipe clamping device. The circular ring moving toward the pipe clamping device drives the slide bar to move away from the L-shaped plate. The slide bar moving away from the L-shaped plate drives the circular plate to move away from the L-shaped plate. The circular plate moving away from the L-shaped plate pushes the pipe inside the pipe clamping device out, thereby preventing the pipe from being stuck inside the pipe clamping device after welding, which affects the equipment's ability to remove the pipe and the efficiency of subsequent processing.

[0016] (3) This invention corrects the position of the pipeline by contacting the pulley frame with the pipeline, thereby preventing the pipeline and the disc from offsetting during the docking process, which would cause the disc and the pipeline to be misaligned during welding, resulting in unqualified products and affecting product processing. The pipeline is surrounded by overlapping baffles to ensure stability during welding. At the same time, it can also prevent sparks from flying during welding from falling between the rack and the gear, causing the gear and rack to not operate normally, resulting in the need for workers to frequently clean them, affecting work efficiency.

[0017] (4) In the invention, when the sliding plate moves toward the disc clamping device, it will contact the pulley, and the sliding plate will push the pulley to move upward. The upward movement of the pulley will drive the support plate to move upward. The upward movement of the support plate will lift the pipe upward, so that the height of the pipe is consistent with the disc during the docking process, preventing height deviation from affecting the welding accuracy. At the same time, when the welding is completed, the rotating plate will reset to block the chip removal groove, preventing the welding slag from flying out of the chip removal groove again, which requires workers to manually clean it, affecting the processing efficiency.
