Preliminary Investigation on the Cause for Crack Intiation in the Internal Drawing Die Holes AITranslate
Abstract AITranslate
Investigation is made on the cause for crack initiation and way for the crack removal in the compact inner holes of YGR7Z cemented carbide drawing dies. It is indicated the said crack is due to too small shrinkage ratio of the compacting die. The test of single compact weight decrease proved that when the shrinkage ratio of the compacting die is increased to over 1.22 , there is no more crack initiated in the compact inner hole.
