Die adjustment mechanism

A die adjustment mechanism comprising:

• a base provided with:
• a die that is configured to apply pressure on a workpiece, the die including multiple modules which are arranged sequentially and capable of sliding laterally relative to the base, and
• a slide rest capable of sliding laterally relative to the base, the slide rest being provided with:
• a shifting fork which is hinged to the slide rest by a hinge shaft, the shifting fork being configured to be clamped:
• (i) with one module of the multiple modules or (ii) between two adjacent modules of the multiple modules, the shifting fork including at least one clamping slot,
• a drive component capable of driving the shifting fork to be clamped with the one module or be clamped between the two adjacent modules, the drive component including a lateral pushing shaft that penetrates through:
• (a) a vertical strip hole formed in the slide rest, and (b) an inclined strip hole formed in the shifting fork, the lateral pushing shaft being configured to slide along the vertical strip hole and cooperate with a hole wall of the inclined strip hole during sliding to push the shifting fork to rotate relative to the slide rest, and
• a pushing member configured to push the lateral pushing shaft to slide along the vertical strip hole,
• wherein the one module or the adjacent modules are configured to be correspondingly clamped into the at least one clamping slot of the shifting fork after the shifting fork rotates relative to the slide rest.
