Abstract

The invention discloses a belt pulley processing method. The belt pulley processing method is characterized by including four steps of previous preparation of a cylindrical blank and a cold rolling die, first cold rolling, secondary cold rolling and post processing. The belt pulley processing method has the advantage that producing efficiency is greatly improved, material utilization rate is high, production cost is effectively reduced, and service life of a belt pulley produced and processed by the belt pulley processing method is greatly prolonged.

Description

technical field [0001] The invention relates to a processing method of a pulley. Background technique [0002] The belt pulley is mainly used for long-distance transmission of power, such as the output of small diesel engine power, agricultural vehicles, mining machinery, machining equipment and so on. At least one circle of belt grooves suitable for the transmission belt is arranged on the outer peripheral surface of the pulley. At present, most of the pulleys are manufactured in the form of lathing, but this manufacturing method has the following disadvantages: (1) The manufacturing process is complicated and cumbersome, especially the belt groove part of the pulley, which requires high processing and is difficult to process, and takes a long time to process , and the efficiency is low; (2), car processing will produce more waste materials, resulting in low utilization rate of materials. Contents of the invention [0003] The technical problem to be solved by the prese...
