High Precision Polishing Cold Heading Die Tungsten Carbide Hexagonal Die

 

 

 The main die is the main cavity in which the blank is produced. It is generally composed of mould steel (such as SKD11/SKD61) and tungsten carbide (cemented carbide).

After the wire is cut off, it is sent to the main die cavity, and the punch strikes the material left outside the main die, causing it to deform into blank.
According to the composition of the main die into ordinary mold and segmented hex die. Ordinary mold refers to the die is a whole, with the method of mechanical (such as wrench) can not be disassembled, used for forming relatively simple products. Segmented hex die refers to the combination of die, can be disassembled, used for molding screw head more complex products, each mold model is consistent with the corresponding equipment die base.
Main die selection: the length of the main die, the length and diameter of tungsten carbide of the main die should be selected according to the specification of the screw. The length of the main die tungsten carbide shall be longer than the length of the screw, the outer diameter of the tungsten carbide shall be larger than the diameter of the screw head, and the R Angle of the main die shall meet the requirements of the drawing.
