The Investigations of the Methods and Standards Assessing the Stamping Class of Deep-Drawing Sheet Metals

Formulating the rational efficient methods and standards assessing the stamping class of deep-drawing sheet metals plays an important role in promoting the wide and efficient uses of sheet metals produced in China.In this paper,the methods and standards in effect assessing the stamping class of deep-drawing sheet metals produced in China were investigated.The problems existing in the methods and standards assessing the stamping class in effect were put forward.The ways developing and perfecting the methods and standards assessing the stamping class were explored.The suggestions for formulating new methods and standards have been put forward.
