Abstract

The invention discloses an automobile clutch cold extruding production technology. The automobile clutch cold extruding production technology comprises the following steps that S1, a blank is selected; S2, the blank is washed, is subjected to sawing blanking and is cut; S3, annealing treatment is carried out; S4, the blank is subjected to phosphorization and saponification; S5, cold extrusion is carried out; and S6, and the workblank is subjected to finish machining. According to the automobile clutch cold extruding production technology, a special-shaped tooth disc hub positive extrusion technology is optimized, products qualified in quality can be produced, the tooth shape compactness and the abrasive resistance are improved, the extrusion load is reduced in the forming process of a special-shaped tooth clutch disc hub, the tooth shape and corner filling effect is good, the surface damage is avoided, and the product quality is improved.

Description

Technical field [0001] The invention belongs to the technical field of processing special-shaped tooth clutch disc hubs of automobile clutches, and specifically relates to a cold extrusion production process of automobile clutches. Background technique [0002] Clutch hubs with special-shaped tooth flanges are usually used in the clutches of light trucks and pickup trucks. The special-shaped tooth flanges are embedded in the clutch driven disc, and the spline teeth inside the steel neck are connected to the output shaft to achieve power. Transmission, which requires the product to have good surface quality and mechanical properties. Limited by the particularity of the product structure, especially the four concave sharp corners on the product's special-shaped tooth flange is the difficulty of forming. At present, it is mainly produced through a series of mechanical processing methods. With domestic steam [0003] With the increasing development of the automobile industry, the mar...
