[0051] In this embodiment, electromagnetic induction switches are installed on the X-axis push cylinder 23 and the Y-axis push cylinder 12 to detect the movement of the X-axis push cylinder 23 and the Y-axis push cylinder 12 and transmit the induction signal to the control host, which can control the operation of the corresponding solenoid valve to realize the push and retraction of the push rods of the X-axis push cylinder 23 and the Y-axis push cylinder 12;

[0052] There is a first spacing between the side wall of the adjustment groove 212 and the side wall of the positioning block 27. The extension portion at the rear end of the positioning block 27 is inserted into the pushing groove 25. There is a second spacing between one side wall of the extension portion of the positioning block 27 and the side wall corresponding to the pushing groove 25. The first spacing and the second spacing are the same, and the distance is equal to the spacing between the two adjacent rows of punching holes 221 on the left and right.

[0053] In this embodiment, a control host and a pneumatic system are installed. The pneumatic system includes an air pump and a control valve. The air pump is connected to the control valve through a connecting pipe, and the control valve is connected to the X-axis push cylinder 23 and the Y-axis push cylinder 12 through a connecting pipe; the air pump, the control valve, the electromagnetic induction switch, etc. are all electrically connected to the control host. The control host and the pneumatic system are common components and will not be described in detail. They are also not shown in the drawings.

[0054] When using this embodiment, the molded piece 100 is first placed in the two middle through grooves 21, so that all the limiting ejector pins 271 are inserted into the corresponding insertion holes 101 on the bottom plate of the molded piece 100 to achieve positioning. At the same time, the elongated support block 22 is inserted into the corresponding lower slot 102 formed on the bottom plate of the molded piece 100, and the plate portion to be processed of the top plate of the molded piece 100 is pressed against the top surface of the elongated support block 22;

[0055] Then, through the punch action of the punch press, the punch needle 60 is pressed down, so that the punch needle 31 punches the corresponding part of the molded part 100, and finally extends into the punching hole 221, and first punches the first row, the third row, the fifth row and other odd rows. After completion, the punch of the punch press returns to its original position, and then the push rod of the Y-axis push cylinder 12 pushes, so that the positioning block 27 moves forward and leans against the front wall surface of the adjustment groove 212. This moving distance is equal to the spacing between the punching holes 221 of the two adjacent rows. At this time, the punch action of the punch press again makes the punch needle 60 press down and punch the corresponding part of the molded part 100. At this time, the processing is the second row, the fourth row, the sixth row and other even rows, which has good effect and high efficiency. Among them, the push rod of the Y-axis push cylinder 12 pushes and retracts through the electromagnetic induction switch detection induction and the push rod is pushed and retracted through the control valve, which has good effect.

[0056] In this embodiment, the specifications of the elongated support block 22 and the upper mold plate 30 can be replaced as needed, thereby replacing the corresponding number of punching holes required to be processed in the molded part 100 to be processed.

[0057] However, when the number of punching holes 221 to be processed is one more than the number of punching needles 60, the entire replacement is troublesome. It is only necessary to move the punch of the punch press, complete a punching, and push the push rod of the cylinder 23 through the X-axis to move the positioning block 27 along the dovetail protrusion 261, so that the side wall of the extended part of the positioning block 27 is pressed against the corresponding side wall of the pushing groove 25. At this time, the molded part 100 moves one position, and then the punch of the punch press moves, and the left side of the original hole position on the molded part 100 and the remaining corresponding processed hole positions can be punched together. At this time, one more row is processed than the original left side. After completion, the punch of the punch press returns to its original position, and then the push rod of the cylinder 12 is pushed through the Y-axis. The movement causes the positioning block 27 to move forward and lean against the front wall of the adjusting groove 212. The moving distance is equal to the spacing between the punching holes 221 of the two adjacent rows. At this time, the punch of the punch press is moved to press the punch needle 60 downward and punch the corresponding position of the formed part 100. At this time, the second, fourth, sixth and other even-numbered rows are processed, while at this time, the odd-numbered rows at the rightmost of all the holes still have unprocessed holes. Then, the punch of the punch press returns to its original position, and the push rod of the cylinder 23 is retracted through the X-axis. Then, the punch of the punch press is moved to process the odd-numbered rows at the rightmost of all the holes. The process is completed. It only needs one clamping to perform multiple punching processes on it, and the effect is good and the efficiency is high.

[0058] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
