Method for machining front wheel cover of automobile

Abstract

The invention discloses a method for machining a front wheel cover of an automobile. The method comprises the steps of placing sheet metal into a blanking die of a blanking machine for blanking, so that blanking dimensions required for product shaping are obtained; placing a semi-finished product obtained after blanking in a heating box for heating till the temperature specified in the process conditions is reached; rapidly placing the heated semi-finished product into a stretching die of a stretching machine for stretching; after the semi-finished product is cooled, conducting measurement, inspection and screening, so that a stretched part with the stretching shape and dimensional precision meeting product requirements is obtained; placing the stretched semi-finished product on a trimming and punching die of a four-station punching machine; after trimming and punching are completed, moving the semi-finished product onto a side trimming and punching die; after side trimming and punching are completed, moving the semi-finished product onto a hole-flanging reshaping die; after hole-flanging reshaping is completed, moving the semi-finished product onto a punching die for punching; and placing a finished product obtained after punching onto a polishing machine, and polishing punched holes and the surface of the finished product. The method is reasonable and convenient to operate; the machined front wheel cover is reasonable in structure and high in quality; the number of punching machines can be reduced; production efficiency can be improved; and manual labor intensity and production cost can be lowered.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a processing method for an automobile front wheel cover. Background technique [0002] The front wheel cover at the front of the car body is a left-right symmetrical piece. Its original process is blanking, stretching, trimming and punching, side trimming and punching, flipping and shaping, and punching 6 stamping processes, which require 6 punching machines , the processing steps are cumbersome and complicated. With the rapid development of the car industry, especially the expansion of the domestic small car market and the urgent need for cost reduction, major OEMs require saving materials, reducing production costs, and improving equipment utilization. Many, the number of required equipment is large and the number of operators is large, but the production efficiency is low and the production cost is high.
