Abstract

The invention discloses a method for manufacturing mechanical drive chain wheel by forging technology, which comprises the following steps: baiting, skinning, coating, heating, upsetting and extruding, annealing, ball blasting, parkerising, saponifying, gear shape cold finishing and finishing. In the method, the warm extrusion technology is adopted to carry out metal volume distribution, thus notonly overcoming waste of raw materials in the prior art, reducing manufacturing costs but also shortening production period and having stable manufacturing technique.

Description

technical field [0001] The invention relates to a production method of a mechanical transmission sprocket, in particular to a method for producing a mechanical transmission sprocket with forging technology. Background technique [0002] In the prior art, the mechanical transmission sprocket or gear is composed of a central part and gear teeth. The two sides of the central part can be designed according to the installation requirements of the working conditions. Large-scale transmission devices require that the transmission sprocket or gear have high strength and precision. Mechanical transmission chain Wheels are generally produced by machining methods, which have the advantage of high gear tooth precision in the production of mechanical transmission sprockets and gears, but the production cycle is long and the manufacturing cost is high. Contents of the invention [0003] The invention provides a method for producing a mechanical transmission sprocket by forging techno...
