Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing die processing, in particular to a punching device for fixing a die core of a wire drawing die. Background Art

[0002] The wire drawing die is a die through which the metal wire passes, so that it gradually changes from thick to thin and reaches the size people need. This special die is the wire drawing die. The common wire drawing die uses natural diamond as raw material, so it has strong wear resistance and long service life.

[0003] The core of the wire drawing die is installed in the tapered hole inside the wire drawing die, and the core is not fixed. When the wire drawing machine stops working, the wire drawing machine will pull the metal wire backward in reverse. When the metal wire is retreating, since the core inside the wire drawing die is not fixed, the metal wire will pull the core out of the wire drawing die when moving in the reverse direction, causing the core to fall off, thereby affecting the subsequent wire drawing operation and reducing the efficiency of the wire drawing operation.
