Function areas of stamping die

1. Wire drawing definition:

Wire drawing is a writing process, which is completed by the metal wire passing through the drawing die hole and applying a pull force to the wire at the exit side of the die. The wire is shrunk and extruded in the die cavity, and its speed increases near the exit of the die hole. Because the volume of the wire is constant, the reduction of the cross section makes it extended and elongated.

2. Function description of each functional area:

Name of each region

Superior performance of innovative "linear" theoretical pass

Import area

The import threading is smooth. We polish the import area so that the drawing liquid (emulsion) can rotate smoothly

Lubrication zone

The polishing of the lubrication area of the traditional drawing die is a little poor. We polish the lubrication area finely to make the wire easy and excessive

Compression zone

"Straight line" working area can reduce drawing force, change point contact to face angle drawing, reduce friction and die wear, deformation structure is more reasonable and stable. It can be drawn smoothly when the incoming line of the previous pass becomes thicker or thinner.

Fixed channel area

The "linear" setting zone can guarantee the diameter, finish and out of roundness of wire rod for a long time.

exporting district

A safety angle in the export area can ensure that the wire material is pulled out without any scar. Life span tends to be longer and longer.

Reverse port area

When the reverse opening is deepened, the tensile stress of the reverse opening can be greatly supported.
