Background In the automatic production of circuit breaker thermal components, the metal support adopts steel generally, and continuous stamping forming is carried out through a multi-station progressive die, and because the structure is complicated, the requirement on dimensional accuracy is high and good electric contact performance and mechanical strength are required to be ensured, the support is still connected through a continuous auxiliary material belt after stamping is finished, separation is realized through a stripping procedure, and the support can enter a subsequent assembly link. At present, a direct shearing mode is generally adopted in the industry for stripping, namely, the connecting ribs between the support and the material belt are cut off at one time by using the upper blanking cutting edge and the lower blanking cutting edge, however, when the method is applied to a precise metal support, the connecting ribs can interfere with the metal support inside the lower die after being directly punched due to the fact that the bending distance of the metal support in the lower die channel is deeper. In order to alleviate the above problems, some enterprises try to introduce a process idea of bending before cutting, namely, pre-bending the connecting ribs to weaken the section strength and release stress, and then finally cutting. However, the existing device for realizing the process is mostly dependent on the integration of a complex sliding block, a wedge or an additional driving mechanism in the die, has compact structure, is difficult to maintain, has poor flexibility, and is difficult to adapt to the rapid switching of different bracket structures.
