1/ GENERAL INTRODUCTION:

The roles ofdifferent parts for tungsten carbide drawing dies blanks.
Theshape and size of different parts for carbide drawing die, depended on thedrawn metal components, performance and size, the size for compression ratio,lubrication, drawn conditions and requirements for products.

Entrance area

Entrancearea to work area are designed for arc transition in favor of material drawinginto the work area, and will not grazed by ridge hole.

The cone angle of lubrication

Lubricationarea is the storage of lubricants, so the the material is drawn can belubricated, in favor of the smooth progress of the drawing process. It’s bymeans of lubrication area to enlarge the work area when drawing die enlarge hole.The height for lubrication size is 0.25 times higher than the height of blank.
