AI Technical Summary
After prolonged use, the existing material guiding mechanism suffers from changes in the elasticity of the rollers, leading to uneven conveying of the stamping strips and even material jamming.
A stamping die with a material guiding mechanism was designed. By setting sliders, insertion rods and balance blocks on the upper and lower die bases, the upper and lower rollers are ensured to maintain the same height when the die is opened. A tie rod and insertion rod reset mechanism is adopted to maintain the stable delivery of the stamping strip.
It enables stable long-term conveying of stamping strips, ensuring the conveying accuracy and smoothness of the stamping strips, and avoiding tilting and jamming problems caused by inconsistent roller heights.
