Elastic compression assemblies for continuously pre-compressing the zipper 6 on the guide block 11 are symmetrically fixed at the middle part of the upper die 5 of the upper punching mechanism; whether the pre-compression pressure is proper or not can be judged by empirically observing the compression deformation condition of the cloth tape of the slide fastener 6, or whether the pre-compression pressure meets a predetermined value can be detected by providing a pressure detector between the pressing plate 9 and the guide block 11.

As shown in fig. 1 to 5, the elastic compression assembly comprises a connecting plate 7, wherein the connecting plate 7 is symmetrically fixed in the middle of an upper die 5, guide posts 8 are respectively vertically and slidably arranged at two ends of the connecting plate 7, a pressing plate 9 which is horizontally arranged is commonly fixed at the bottom ends of the two guide posts 8, and the pressing plate 9 is annular; the guide post 8 is coaxially sleeved with a compression spring 10, one end of the compression spring 10 is tightly propped against the bottom surface of the connecting plate 7, the other end is tightly propped against the top surface of the pressing plate 9, the pressing plate 9 continuously pre-presses the zipper 6, and the bottom end of the upper die 5 can pass through a hole in the pressing plate 9.

As shown in fig. 1 to 4, two guide blocks 11 are symmetrically fixed on the top surface of the workbench 1 and positioned on two sides of the lower punching mechanism, and the guide blocks 11 are arranged at corresponding positions below the pressing plate 9; the top surface of the guide block 11 is provided with a guide groove 1101 for the passage of the teeth of the slide fastener 6, the width of the guide groove 1101 is equal to the width of the teeth of the slide fastener 6, and the pressing plate 9 pre-presses the slide fastener 6 on the guide groove 1101.

The guiding groove 1101 guides and limits the zipper 6, namely limits the teeth of the zipper 6, so that the front and rear positions of the zipper 6 are limited, and the punching precision is improved.

The utility model relates to a working principle of a zipper punching device, which comprises the following steps: the telescopic end of the first telescopic rod of the upper punching mechanism moves downwards through the control system, when the pressing plate 9 is in contact with the zipper 6, the telescopic end continues to stretch, the connecting plate 7 presses the compression spring 10, the compression spring 10 generates precompaction force on the pressing plate 9, and when the pressure of the pressing plate 9 on the zipper 6 reaches a preset value, the telescopic end of the first telescopic rod stops stretching; when the pulling mechanism 3 finishes the pulling operation, the telescopic end of the first telescopic rod continues to stretch and drive the upper die 5 to move downwards, and meanwhile, the telescopic end of the second telescopic rod of the lower punching mechanism stretches upwards and drives the lower die 12 to move upwards, namely the upper die 5 and the lower die 12 move relatively, the upper die 5 and the punching die 1201 respectively abut against and press the upper surface and the lower surface of the zipper 6, and the ultrasonic generator vibrates at high frequency, so that the zipper 6 is punched. Because the pressing plate 9 generates friction resistance to the zipper 6 to overcome the inertia effect, the zipper 6 does not move continuously, thereby further improving the punching precision.
