Causes Analysis and Process Improvement for Excessive Precision of Head Cutting Forming
In order to improve material utilization and avoid the waste of raw materials,a certain company cancelled the flanging of the brim left during the head forming process.However,there were some problems such as the height difference between the two sides and the precision error after the flanging was canceled.Analyzed the reasons for a series of problems occurring after the edge-cutting forming of the flangeless head,the quality and precision of the cutting edge of the head were improved by improving the die structure,designing the special cutting edges marking tool,reforming the existing cutting edge tire position and designing the special testing sample of the head,so that the head of the qualified rate was more than 98％and material savings reached 10％.At the same time,in the whole head cutting edge of the process of work efficiency increased by 50％,and the operator's work intensity was greatly reduced.
