The invention relates to a manufacturing method for an engine-oil filter cover by means of cold forging for heavy equipment. The engine-oil filter cover is manufactured sequentially according to the following steps of aluminum-ingot manufacturing, softening heat processing, first cold forging, coating processing, secondary cold forging, secondary inner-surface machining and hardening heat processing. According to the manufacturing method and manufacturing device for the the engine-oil filter cover by means of cold forging for the heavy equipment, the engine-oil filter cover of the heavy equipment is produced by a cold-forging method, so that the problems of air-hole generation and machining during cutting manufacturing after casting in the past are solved, the engine-oil filter cover has smaller rejection rate and excellent quality, manufacturing working procedures can be decreased, and the manufacturing cost is lowered.
Description
technical field [0001] The present invention relates to a method and a device for manufacturing an oil filter cover for heavy equipment by means of cold forging. Background technique [0002] Generally speaking, when designing the extrusion forging process, according to the cold forging ratio, the extrusion ratio is designed within 75%, so as to prevent mold damage and improve quality. However, among automotive parts, there are many parts that exceed the normal molding ratio. When developing such parts, the normal forging design is used, resulting in mold breakage, low productivity, and quality problems, resulting in increased manufacturing costs. As for the product to be developed in the present invention, it is difficult to develop a product with a front-to-back extrusion ratio of 85% or more, which is much larger than 75%, so it is a part that forging companies avoid developing. [0003] As far as the oil filter cover of heavy equipment using hydraulic pressure is concer...
