Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of welding machines, in particular to a heat dissipation cooler for a friction welding machine. Background Art

[0002] A friction welder generates heat during rotation and then applies appropriate pressure to complete the weld. Depending on the energy input method, friction welders are categorized into continuous drive and inertia types. The former consists of a fixture, transmission mechanism, pressure mechanism, brake, and control device; the latter consists of a fixture, transmission mechanism, flywheel, pressure mechanism, and control device.

[0003] The friction welding machine relies on the high heat generated by friction during welding to melt and reorganize the welded parts to achieve welding. This requires a higher temperature. Once the welding temperature is reached, it means that the welding is completed and heat dissipation and cooling are required. The traditional method is generally natural cooling or air drying cooling. This method is more cumbersome to operate. At the same time, long-term storage affects the integrity of the welded parts. In addition, the efficiency of artificial cooling is low, and cooling operations cannot be performed immediately after welding is completed. Summary of the Invention

At this time, negative pressure is generated in the air transfer pipe, and the detection column under the limit block moves downward, indicating that the heat dissipation is completed. Only then can the next round of welding operation be carried out. This welding method can efficiently realize the heat dissipation and cooling process in the welding operation, improve welding efficiency, and highly improve welding quality. At the same time, it can automatically adjust the welding cooling process and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
