Problems solved by technology

Although this kind of planing processing can also complete the processing of warped fin heat exchange tubes, the processing time is too long, and the thickness of warped fins is uniform, the root strength of warped fins is insufficient, and warped fins are easy to fall off, which cannot guarantee the production of heat exchangers. Manufacturers demand for mass production and quality

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a mechanism for strengthening the processing cutterhead of warp fin heat exchange tubes and an operation method thereof. Background technique [0002] Warped fin heat exchange tubes have been widely used in the field of heat exchangers in recent years. Because they can increase the heat dissipation area of ​​heat exchange tubes, and the heat transfer tube body is formed by planing, the heat transfer effect is good, but due to Processing difficulties have been unable to meet the needs of industrial production. The main difficulty in processing is that there has not been an efficient processing cutter head. The current processing method is to plan out one warp at a time. How many warps are there on the circumference and length of the heat exchange tube, it needs to be planed as many times as possible. Although this kind of planing processing can also c...
