[0044] The working principle and use process of the present invention: When using the present invention, it is first necessary to start the hydraulic press 1 set on the fixed plate 2, and the operation of the hydraulic press 1 drives the punch 5 fixedly connected to one end of the output shaft of the hydraulic press 1 to move downward, and the bottom end of the punch 5 is provided with a punching block 9, and a die 4 is provided just below the punch 5, and a punching groove 8 is provided on the die 4 corresponding to the position of the punching block 9, and a sliding hole 10 is provided at the bottom end of the punching groove 8, one end of the sliding hole 10 is fixedly connected to the telescopic groove 3 set on the inner side of the die 4, and a slider 11 slides in the sliding hole 10, and the slider 11 is located on the inner side of the telescopic groove 3, and a first electric push rod 12 is provided below the slider 11, and the bottom end of the first electric push rod 12 is connected to the telescopic groove 3. The bottom end of the inner side of the groove 3 is fixedly connected, and the bottom end of the punch 5 is also fixed with a sliding rod 18, and the bottom end of the sliding rod 18 is provided with a piston 6, the sliding rod 18 slides with the compression groove 13 provided at the top of the die 4, and the side wall of the piston 6 slides with the side wall of the compression groove 13, and an air delivery groove 14 is provided on the inner side of the compression groove 13, one end of the air delivery groove 14 is fixedly connected with the telescopic groove 3, and a closing valve 17 is provided at one end of the air delivery groove 14 located on the inner side of the telescopic groove 3. In this way, when the hydraulic press 1 starts to drive the punch 5 to move downward, it will correspondingly drive the stamping block 9 fixed at the bottom end of the punch 5 to slide with the stamping groove 8 and then stamp the material plate provided on the die 4 to form the punching sheet, and when the punch 5 moves downward, it will drive the sliding rod 18 to move downward synchronously, and The piston 6 fixed at the bottom end of the sliding rod 18 will also move downward along the side wall of the compression groove 13 as the sliding rod 18 moves downward, thereby compressing the air inside the compression groove 13, and the compressed air inside the compression groove 13 will be transported to the inner side of the expansion groove 3 along the air delivery groove 14 connected to the compression groove 13. When the air delivery groove 14 delivers gas to the expansion groove 3, the air closing door 17 set on the side wall of the expansion groove 3 will be correspondingly opened by the compressed air, and when the piston 6 moves to the bottom end of the compression groove 13, the punching block 9 will complete the punching of the material plate, and then move upward under the drive of the hydraulic press 1, thereby driving the piston 6 to move upward and drive the inner side of the compression groove 13 to form a negative pressure, and the air closing door 17 set inside the expansion groove 3 will open in the expansion groove 3.
