Engine belt wheel hub production process

Abstract

The invention discloses an engine belt wheel hub production process. The engine belt wheel hub production process comprises the steps of a, ingredient preparing, b, blank manufacturing, c, heat treatment, d, machining, e, spraying, and f, inspecting and packing; in the step b, blank manufacturing comprises the steps that the processing materials prepared in the step a are melted through an oil furnace or an electric furnace at first, then molten metal is subjected to casting cooling molding, and X-ray flaw detection is conducted on a molded blank finally; wherein, before molten metal casting operation, an inoculant is added into the molten metal to conduct furnace front deoxidation inoculation treatment, and the inoculant is obtained in the mode that montmorillonite, rhenium, graphite powder, silicon barium and a silane coupling agent are mixed, heated, melted and crushed into particles with the average grain diameter being 10-15 mm after water cooling and drying finally. The engine belt wheel hub production process is simple in step and easy to operate and master; meanwhile, the structure nonuniformity can be reduced; and the machining precision, the matrix strength and the durability are improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to the production process of an engine pulley hub. Background technique [0002] The hub of the engine pulley belongs to the hub type parts, generally relatively large in size, and the manufacturing process is generally based on casting and forging. The pulley of the engine is mainly used for the energy absorption and release of the mechanical drive train of the engine, and is an indispensable part for energy storage and transmission. [0003] Generally, the preparation process of the engine pulley hub is mainly based on forging, but in the traditional forging process, there are many kinds of materials and magazines, which will cause a lot of waste of raw materials, and the cost is high. In addition, the internal resistance structure of the cast casting There are defects such as uneven density and uneven hardness, which lead to pulley hubs, insufficient strength and durability.
