In addition, both of the above two schemes for limiting the impact force of the pressing block have the problem that the pressing block can not be immediately stopped when the device is out of control, so that the steel bending equipment for processing the vehicle accessories can limit the impact force of the tail end of the upper die, can not generate heat accumulation failure and can not move along with the lower die at high speed.
