Processing method of automobile engine front cover

Abstract

This invention relates to an automotive engine front end cover processing method. The automotive engine front end cover processing method includes uncoiling and straightening, machining a part through fine blanking, wherein the center is provided with a shaft hole, a round blind hole is arranged beside the shaft hole, and a plurality of round holes are circumferentially and uniformly formed in the part; checking and sorting products without scratches; cleaning and ensuring no residual drops, no rust and fine blanking oil left; performing deburring; sorting products without scratches again; machining the blind hole in a final molding process; performing high-frequency quenching; performing shot blasting; performing surface coarse grinding on a paralleled surface grinding machine; chamfering the round holes which are circumferentially and uniformly formed in the part; tapping the round holes which are circumferentially and uniformly formed in the part; machining the shaft hole of the part to a final size; performing double-surface accurate grinding on a vertical double-sided grinder; performing deburring; performing degaussing; performing cleaning; performing packaging for storage. The automotive engine front end cover processing method can meet requirements of dimensional accuracy and location accuracy of products, enables the part machining process to achieve the most simple and optimized state, and reduces processing cost.

Description

technical field [0001] The invention relates to a processing method for an automobile engine front end cover. Background technique [0002] The traditional processing method of the front end cover of the automobile engine is the powder metallurgy method (the process of mixing metal or non-metal powders, pressing them into shapes, and sintering them at a temperature lower than the melting point of the metals, and using atomic diffusion between the powders to bond them), Products processed by this method, although the injection molding technology has almost no restrictions on the complex shape of the formed parts, but due to the large amount of binder added, the workpiece will be deformed due to the influence of gravity during the heating process, so It is often necessary to add a more complex and expensive special degreasing process, making injection molding technology more expensive than conventional powder metallurgy technology.
