[0002] A tap is a tool for processing internal threads. According to its shape, it can be divided into spiral taps and straight-edged taps. The shank of the tap is forged and narrowed by a forging press, also called a shrinking shank; The channel for stamping and placing the shank by the punch ensures the formability during forging and stretching of the reduced shank. However, the die assembly in the prior art has unreasonable structural design, poor pressure bearing capacity, and short service life, which leads to the forging and pressing of the reduced shank. Poor formability and low processing efficiency
