Conventional circuit breaker mounts are typically integrally stamped and formed from multi-station progressive dies. The multi-station progressive die comprises an upper die plate, a lower die plate, and a punching station, an obtuse-angle bending station and a direct bending station which are arranged between the upper die plate and the lower die plate in sequence. After the support is punched, the support is transferred to the next procedure, and the screw hole is worked, so that the processing mode has low efficiency. Aiming at the problems, a progressive die with an in-die power wire function is also arranged on the market, but the circuit breaker mounting frame is small in size, so that accurate power wires in screw holes are difficult to realize, and the rejection rate is high.
