摘要
Abstract
The formation process and mechanism of the high point of the automobile stamping outer covering were analyzed.The influence of the type and size of the foreign body,the thickness of the plate and the die gap on the high point height was studied.At the same time,the influence of the high point height of the automobile stamping covering on the long wave,short wave and fresh reflection after coating was studied.The results show that the height of high point increased with the increase of particle diameter and elastic modulus.As the thickness of the plate increased,the height of the high point increased,with the decrease of the die clearance,the height of the high point increased.The long wave increased with the increase of the height of the high point,and there was a positive correlation.The relationship between short wave,freshness and the height of the high point was weak.The control threshold of the height of the high point in the stamping workshop of a main engine factory was 10.5 μm.关键词
