A rolling forming die for two-way corrugated fins comprises a first rolling assembly (1) and a second rolling assembly (2) which are used for rolling plate materials into fins; the first rolling assembly (1) and the second rolling assembly (2) are mutually meshed; at least one rolling wheel group (3) which is used for face-to-face rolling is arranged on the first rolling assembly (1) and or the second rolling assembly (2); the rolling wheel group (3) is formed by two rolling wheels (4) which are closely adhered; convex blades (5) with cutting edges are arranged on the rolling wheels (4); the cutting edges of the rolling wheels (4) are formed towards a close adherence direction of the two rolling wheels (4); the two closely adhered rolling wheels (4) are formed into a closely adhered cutting edges which are overlapped; meshing wheel surfaces of the rolling wheels (4) are provided with at least one forming toothed cutter (6) and at least one forming toothed bottom (7); the forming toothed cutter (6) is used for enabling the plate materials to be in flat top rectangular wave states; the forming toothed bottom (7) which is formed in the bottom of the forming toothed cutter (6) is used for enabling the plate materials to be in flat top rectangular wave states.
Description
technical field [0001] The invention relates to the technical field of fin manufacturing and processing equipment, in particular to a rolling die with bidirectional corrugated fins. Background technique [0002] At present, with the development of mechanical equipment such as air conditioners, there are many updates in its structure, especially the heat dissipation structure. Fins are structural components used for heat dissipation in air conditioners and other equipment. The structural requirements of heat dissipation fins are also different, and the required fin structure size is also completely different. According to market demand, it is necessary to manufacture a bidirectional corrugated fin. In the prior art, the fins are generally made by stamping. However, this kind of fins often cannot be stamped and formed at one time, which makes the process cumbersome, and it is difficult to achieve the required structure by stamping two-way waves. It needs other processing equip...
