The operation of a stamping die relies on the power drive of the equipment. Under normal production conditions, the die's movement is in a controllable state of uniform speed or uniform acceleration, and the structural stress is within a stable range. However, when a sudden emergency braking is triggered, the equipment will rapidly reduce its speed in a very short time. At this moment, the inertia generated by the die's own mass cannot instantly offset the sudden change in motion, thus generating a powerful inertial impact force.

The intensity of this impact force is directly related to the die's weight and operating speed. The faster the speed and the greater the mass, the more astonishing the inertial impact force generated during emergency braking. It does not act uniformly on the die but concentrates its impact on critical structures such as connection parts, guide components, and core stress areas.

During emergency braking, the damage to the structure caused by the inertial impact force of the stamping die is not limited to a single component but triggers a chain reaction, gradually disintegrating the integrity of the die from local to overall damage, ultimately leading to production stoppage.

At the core stress-bearing component level, critical forming components such as the punch and die are highly susceptible to problems such as edge chipping and surface deformation under the impact of the inertial impact force. These damages not only directly lead to decreased precision in stamped parts and the production of scrap, but also, due to minute deformations of components, alter the clearance fit of the die, further exacerbating friction and wear during subsequent operation, creating a vicious cycle.

At the level of connection and support structures, inertial impact forces can cause severe impacts on connecting components such as die fasteners, guide pillars, and pressure plates, leading to bolt loosening, deformation, or even breakage, and guide components shifting or jamming. Once the connection structure fails, the overall stability of the die collapses, not only failing to guarantee stamping accuracy but also, in severe cases, causing die components to detach, resulting in equipment damage and even threatening the personal safety of operators.
