Problems solved by technology
At present, some heat exchangers on the market use circular tubes with poor heat exchange effects as heat exchange devices. The reason is that the circular flat tubes are difficult to manufacture in the production process, the manufacturing process is cumbersome, the manufacturing efficiency is low, and the space required for production equipment is large. question
[0003] The processing technology of the existing circular flat tube mainly includes: multi-pass roll forming, the forming rolls are arranged in a straight line, and the production equipment occupies a large space; drawing forming also has the problem that the production equipment occupies a large space ;Application No. 201310746574.9 Chinese patent discloses a manufacturing method of flat tube hot press forming, the processing technology of this method is relatively complicated; and the above-mentioned forming process can only process the cross section, and cannot produce flat tubes with radians

The invention relates to a device and process for integrally forming an annular flat tube. The device comprises a section pre-forming system, a roll bending system, multi-pass rolling flattening forming rollers and inter-pass guide devices, wherein the output of the section pre-forming system is matched with the input of the roll bending system, the multi-pass rolling flattening forming rollers are sequentially arranged at the output of the roll bending system, and the inter-pass guide devices for guiding workpieces to move are distributed among the multi-pass rolling flattening forming rollers. According to the device and method, the functions of flat section machining and roll bending into a ring are integrated, the occupied space is reduced, and the device and method have the beneficial effects of less clamping frequency, a simple mechanical structure, high production efficiency, low production cost and the like.
Description
technical field [0001] The invention belongs to the technical field of metal forming, and in particular relates to an annular flat tube integrated forming device and process. Background technique [0002] The annular flat tube is an important part of the aerospace industry, which plays an important role in the separation device of the launch vehicle; at the same time, in the finned flat tube heat exchanger, the annular flat tube is indispensable as the final heat exchange execution part few. At present, some heat exchangers on the market use circular tubes with poor heat exchange effects as heat exchange devices. The reason is that the circular flat tubes are difficult to manufacture in the production process, the manufacturing process is cumbersome, the manufacturing efficiency is low, and the space required for production equipment is large. question. [0003] The processing technology of the existing annular flat tube mainly includes: multi-pass roll forming, the formin...
