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.
The carbide cold heading
dies we supply for customer including:
1. Straight hole insert mold
