The invention provides a spinning forging method for a high-inclination disc forging. A plurality of steps are spun on a round billet, and relative to a traditional machining method, the weight of theforging is reduced by about 25%-35%, the machining time is reduced by 20%-30%, and the production cost is lowered by 20%-30%. Moreover, the method is capable of reserving many metal fiber flow linesformed by forging; and compared with the traditional machining method, the strength and the hardness of the machined finished product can be increased by 15% and above, so that the service life of theproduct is prolonged.
Description
technical field [0001] The invention belongs to the technical field of forging forming of cake forgings, and in particular relates to a spinning forging method of cake forgings with a large gradient. Background technique [0002] Such as figure 1 As shown, the high-slope cake forging refers to the round table forging with the bottom angle α not greater than 60°. The difference between the radius R of the large end and the radius r of the small end of this forging is large, and the height H is relatively small. Round table forgings, forging such forgings by traditional technology usually forges steel ingots into cylindrical cake-shaped blanks, and then removes excess material on the blanks to the finished product size through machining. This processing method not only wastes a lot of raw materials, but also consumes a lot of machinery. The processing time occupies the machining equipment, the production efficiency is low, the production cycle is too long, and the delivery ti...
