1. Schematic diagram of the functional areas of the drawing die:

2. Drawing definition of wire:

Wire drawing is a process in which the metal wire is passed through a drawing die hole and a pulling force is applied to the wire at the exit of the die. The wire is tapered by shrinkage extrusion in the cavity, and its velocity increases near the exit of the die hole. Since the volume of the wire is constant, the reduction in cross section causes it to be stretched and elongated.

3. Description of the functions of each functional area:

The name of each region The superior performance of the innovative "straight" theoretical hole type

The import area is smooth, and we polished the inlet area so that the drawing liquid (milk) smoothly swirls.

Lubrication area The polishing area of the traditional drawing die is slightly poorly polished. We finely polish the lubrication area to make the wire easily over-exposed.

Compression zone The “straight” working area can reduce the pulling force. The changing point contact is the joint drawing, which reduces friction and mold wear, and the deformation structure is more reasonable and stable. The upper pass line becomes thicker or thinner and can be pulled smoothly.

Dingjing Zone The “straight” zone can guarantee the precise diameter, finish and out-of-roundness of the wire for a long time.

Export Zone The safe corner of the export zone will ensure that the wire is pulled out without scratches. Life expectancy is getting longer and longer.

The counter-mouth area is deepened, which can support the tensile stress of the counter-mouth.
