[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, the present invention sets a rotating plate, a clamping plate, a first cylinder and a clamping frame. The elbow is fixed on the metal conveyor belt for transportation through the clamping plate. The rotating plate fixes the elbow through the double-headed push rod and the clamping frame, and the first cylinder drives the rotating plate and the elbow to move up. After moving up, the second motor drives the first cylinder, the rotating plate and the elbow to rotate to the left, so that the elbow moves to the top of the fixed mold base on the left, and then the elbow falls to the inner side of the fixed mold base and the movable mold base and is clamped. At this time, the second motor drives the rotating plate to rotate again to the top of the metal conveyor belt to continue clamping and picking up the goods. The elbow is automatically loaded without the need for worker operation and will not cause harm to the workers.

[0018] Second, the present invention is provided with a cooling chute, a nozzle, a push plate and a water inlet pipe. After the elbow is finalized, the hot stamping seat moves up. At this time, the two second cylinders are controlled to operate, driving the movable die seat at the output end to move outward, so that the movable die seat is separated from the fixed die seat. After separation, the two elbows automatically fall into the cooling chute on the inner side of the processing table. At this time, the valve on the water inlet pipe is opened, so that the external cooling water enters the nozzle through the bellows and the water inlet pipe, and sprays water mist through the nozzle. The water mist cools the high-temperature elbow. At the same time, the first electric push rod drives the push plate at the output end to extend after operation, so that the push plate pushes the elbow to move to the left, and slides to the left under the action of the thrust. While sliding, the water cooling of multiple nozzles causes the elbow to gradually drop to a normal temperature, and slides through the left side of the processing table to collect the material.

[0019] Third, the present invention arranges a third motor, a rotating rod, a cleaning brush and a vacuum cleaner, and controls the operation of the second electric push rod to drive the mounting shell of the output end and the third motor to move to the left, so that the third motor drives the rotating rod of the output end to move above the fixed mold base and the movable mold base. At the same time, the operation of the third motor drives the rotating rod to rotate. When the rotating rod rotates, inertia drives multiple cleaning brushes to open outward through the movable ring, so that when rotating, the fixed mold base below, the movable mold base and the hot stamping base above are cleaned. At the same time, two vacuum cleaners are operated to absorb the debris generated by the cleaning of the inside of the protective shell through the dust hood, so that the fixed mold base, the movable mold base and the hot stamping base are kept clean.
