Manufacturing process method of aluminum alloy stamping die surface

Abstract

The invention discloses a manufacturing process method of an aluminum alloy stamping die surface. The manufacturing process method includes the following steps that a protruding part profile is machined in the middle of a male die; an annular process supplementing surface is machined on the circumferential side of the part profile of the male die, so that the process supplementing surface inclinesdownwards in the direction towards the edge of the male die along the part profile, and the process supplementing surface and the part profile jointly form a die core; an annular flat edge pressing ring profile is machined on the circumferential side of the process supplementing surface of the male die; and a plurality of concave drawing ribs are machined on the edge pressing ring profile of themale die, so that the drawing ribs are annularly arranged on the circumferential side of the part profile at intervals. By setting a gentle edge pressing ring and the inclined process supplementing surface and formulating a slight drawing process scheme, punch forming of an aluminum alloy is realized; and by adopting the partition type drawing ribs, the portion, between every two adjacent drawingribs, of the edge pressing ring profile is flat, and therefore the output in metal removal in the aluminum alloy stamping process can be effectively reduced, and then the forming quality of the aluminum alloy is improved.

Description

technical field [0001] The invention relates to the technical field of automobile die design, in particular to an aluminum alloy stamping die surface manufacturing process method. Background technique [0002] Due to the needs of environmental protection and energy saving, lightweight has become an inevitable trend in the development of automobiles. Automobile lightweight is very important to reduce body weight, reduce fuel consumption and reduce vehicle emissions. Considering many aspects, aluminum alloy is the preferred material for automobile lightweight. Studies have shown that every 1Kg of aluminum used in a car can reduce the weight of 1Kg. For every 10% weight reduction of the car, the fuel consumption can be reduced by 6-8%, and the exhaust emission can be reduced by 4%. It can be seen that the research on aluminum alloys in the field of automobile manufacturing is imminent, and it is also an inevitable trend. However, the material elongation of aluminum alloy is ...
