Welding is a method of joining metals or other thermoplastic materials by heating, high temperature or high pressure. When the metal bellows is used for processing, it is necessary to perform circular annular seam welding on the metal bellows. However, in the existing metal processing welding devices, when the metal bellows is welded, most of them dissipate heat by natural cooling. The metal bellows is taken out after cooling for a period of time. However, the cooling process is uncontrollable. If the natural cooling time is not enough when the metal bellows is taken out, it is easy to burn the staff, resulting in poor practicality and reduced production efficiency. Utility Model Content

The cylinder 1 6 and the cylinder 2 7 are close to each other. A nozzle 8 is installed at the outlet on one side of the fixed hole, the inlet of the cylinder 1 6 is connected to the outside air, the inlet of the cylinder 2 7 is connected to a liquid storage tank 9 arranged on one side of the workbench 4, the liquid storage tank 9 is connected to the fixed hole 5, the interior of the cylinder 1 6 and the cylinder 2 7 are sealed and slidably connected with a T-bar 10, the top of the T-bar 10 is connected to a slider 11, the slider 11 is slidably installed in a movable groove, and a lifting mechanism connected to the slider 11 is provided inside the fixed hole 5 for automatically lifting the processed metal parts.

[0020] During work, the metal bellows is inserted into the fixing hole provided on the workbench, and is clamped and fixed by the clamping mechanism, and then welded by the welding head. During the welding process, the workbench drives the metal bellows to rotate for all-round welding. After completion, the lifting mechanism is started to release the clamping of the metal bellows, and the processed metal parts are automatically lifted up, which is convenient for the staff to take. In this process, the lifting mechanism will first drive the T-bars in the cylinder one and the cylinder two to move upward, thereby squeezing the air in the cylinder one and the coolant in the cylinder two, so that the gas and the coolant are sprayed out from the nozzle respectively, and the processed metal bellows are automatically cooled to avoid scalding the staff; similarly, after the processed metal bellows is taken out, the lifting mechanism is started to return to its original position, and at the same time, the T-bars in the cylinder one and the cylinder two are driven to move downward, and the external gas and the coolant inside the liquid storage tank are respectively sucked into the cylinder one and the cylinder two, thereby preparing for the next welding. A liquid filling port is provided on one side of the liquid storage tank, which is convenient for adding coolant thereto.

[0021] A motor 12 for driving the workbench 4 to rotate is installed below the support base 1. The motor drives the workbench 4 to rotate to adjust the welding position.

When clamping, the metal bellows is placed in the middle of the clamping rod, and then the electromagnet is energized. According to the principle of opposite magnetism attraction between electromagnets, the clamping rod clamps and fixes the metal bellows.

[0023] The lifting mechanism includes a hydraulic cylinder installed inside the fixing hole, a top plate connected to the output shaft end of the hydraulic cylinder, and a top rod 14 installed above the top plate. The two sides of the top plate are respectively connected to the slider 11. The hydraulic cylinder works to drive the top plate, the top rod 14 and the slider 11 to move up and down, and the slider drives the T-bar to move up and down in the cylinder body one and the cylinder body two respectively.

[0024] One-way valves are installed on the inlet and outlet of the cylinder 1 6 and the cylinder 2 7. It should be noted that the one-way valve at the inlet of the cylinder 1 6 only allows external gas to enter, and the outlet only allows internal gas to discharge, and the one-way valve at the inlet of the cylinder 2 7 only allows coolant to enter, and the outlet only allows internal coolant to discharge, so as to achieve the purpose of automatically cooling the metal bellows.

[0025] A filter is installed at the bottom of the fixing hole 5, and the cooling liquid sprayed out will fall into the inside of the fixing hole, and after being filtered and purified by the filter, it will flow back into the liquid storage tank to achieve the purpose of recycling.
