Rolling continuous corner-pressing chamfer forming method for dual-metal strip with oil cavity in copper alloy face

The invention provides a novel continuous chamfer forming method for a dual-metal strip with an oil cavity and discloses a rolling continuous corner-pressing chamfer forming method which can be suitable for the dual-metal strip with the oil cavity. Compared with a conventional corner planing method, the rolling continuous corner-pressing chamfer forming method has the following advantages that thesituation that pit burrs occur at a chamfered opening of the strip can be avoided, the chamfered opening of the strip with the oil cavity can be more dense and smoother, abrasion resistance of a material is improved, the chamfered opening can be in smooth transition, an opposite grinding shaft is prevented from being damaged, the material can be fully utilized, no waste is generated, environmentprotection of the process is embodied, the production work efficiency can further be greatly improved, and the machining cost is lowered. 本发明提供了种新型的有油穴双金属带料的连续成型倒角方法，即种能适用于有油穴的双金属带料的辊压连续压角成型倒角方法。相比常规的刨角方法,本发明的辊压连续压角成型倒角方法有以下优点
