Abstract：

|
During the drawing process,there are quality problems,such as corrugations,cracks and so on in the automobile ex-headlight paraboloid reflector,which cause that the product could not meet the relative national standard about the light-style and light distribution.Through analysis,it is found that the reasons for these problems are the control of roughcast in wrong condition in the drawing process and there exists unbalance flow in the process of material redistribution.Through study and practice in production,it gives an optimized project of drawing process and mold structure designed by regulating drawing parameter and setting drawbead on mould to solve the existent problem in drawing process.
