in the third step, after the punching and trimming work of the substrate is finished, the substrate is moved to the trimming and bending station through the feeding assembly (5), the first hydraulic cylinder (2) is started again, the upper die assembly (3) is driven to move downwards, the upper die assembly (3) is matched with the lower die assembly (4), and trimming and bending are carried out on the substrate;

in the fourth step, after the substrate finishes trimming and bending work, the substrate is moved to the next left-right bending station through the feeding assembly (5), the first hydraulic cylinder (2) is started again, the upper die assembly (3) is driven to move downwards, the upper die assembly (3) is matched with the lower die assembly (4), and the left side and the right side of the substrate are bent;

in the fifth step, after the substrate is bent, the substrate is moved to the next punching and bending station through the feeding assembly (5), the first hydraulic cylinder (2) is started again, the upper die assembly (3) is driven to move downwards, the upper die assembly (3) is matched with the lower die assembly (4), and punching and bending are carried out on the substrate;

and in the sixth step, after the substrate is bent, the substrate is moved to the next upper and lower bending station through the feeding assembly (5), the first hydraulic cylinder (2) is started again, the upper die assembly (3) is driven to move downwards, the upper die assembly (3) is matched with the lower die assembly (4), the upper side and the lower side of the substrate are bent, and the continuous punch forming work of the communication equipment shell is completed.

8. The continuous press molding method of a communication device case according to claim 7, wherein: in the first step, before the continuous punch forming processing of the communication equipment shell is carried out, debugging work is firstly carried out through a debugging module (62).
