Problems solved by technology

[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 uneven density and hardness, which lead to defects such as pulley hubs, insufficient strength and durability

Abstract

The invention discloses a production process of an engine pulley hub, comprising: step a: preparing ingredients; step b: manufacturing blanks; step c: heat treatment; step d: machining; step e: spraying; step f: inspecting packaging; step b Manufacturing blanks in the process includes: firstly using an oil furnace or an electric furnace to melt the processing material prepared in step a, then casting and cooling the melted molten metal, and finally performing X-ray flaw detection on the formed blanks; wherein, before the molten metal casting operation Add an inoculant to the molten metal for deoxidation inoculation treatment in front of the furnace. The inoculant is mixed with montmorillonite, rhenium, graphite powder, silicon barium and silane coupling agent, heated and melted, and finally water-cooled, dried and broken The average particle size of the granules is 10-15mm. The production process of the engine pulley hub has simple steps, simple operation and easy mastery, and can reduce the unevenness of the structure, and improve the processing accuracy, matrix strength and durability.

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.
