The present invention relates to belt pulley and make field, particularly a kind of monolateral have little spoke architecture automobile decoupling zero motor pulley manufacturing installation and technology.
Background technology
Since two thousand eight, traditional electric motor of automobile belt pulley is gradually by a kind of patented product---and automobile decoupling zero motor belt wheel assembly (One-way clutch Alternator Decoupler is called for short OAD) replaces.The flatness of electrical motor gearshift because the latter has been greatly improved can fuel-economizing more than 2%～3%, and its anti-fatigue ability doubles, so market prospects are very wide.
Automobile decoupling zero motor belt wheel assembly is the patent of LITENS (Leiden) company in invention in 2003 at first; Through improving, do the change of some structures afterwards, invented out OAD of new generation; Structure is different slightly between the two; Its principle and function are basic identical, and Leiden company has applied for the patent of invention of automobile decoupling zero motor belt wheel assembly (OAD) in the China's Mainland, and its patent No. is ZL 03816543.0.
The method of making belt pulley emerges in an endless stream; Form tubular blank with plate, pipe or casting earlier mostly for a long time; After cut is removed the technology of excess stock, make the technology of belt pulley and catch up from behind because of the characteristics of its high-quality, high efficiency, material saving and rotate cold extrusion in recent years., the existing manufacturing process of the belt pulley in the decoupling zero electric motor of automobile belt pulley assembly still rests on original state.Its reason is: well-known; Automobile industry parts manufacturing technology standard and technological requirement are higher than other general industry parts manufacturer's standards; And very thin thickness at the bottom of the pulley groove among the OAD; If with the such belt pulley of rotation cold extrusion manufacturing, swing roller must radially apply very big pressure to material base.But because it does not have spoke; Material base can't be by reliable grip in rotation cold-stamped moulds of industrial equipment; Because rotation cold extrusion equipment only can give the material base clamping force in the axial direction, and the face area of steel pipe material base is very little, so can't be by reliable grip; When swing roller was exerted pressure to material base, material base must skid.In view of this, do not see the manufacturing process of processing the OAD belt pulley with the rotation extrusion method up till now as yet.In fact, the automobile of the useful rotation cold-extrusion technology manufacturing of institute at present belt pulley all requires belt pulley for spoke architecture is arranged, so that feasible process.
