Specifically, the upper punching head 4 is used to penetrate the electrical cabinet panel into the lower punching slot 5 through the upper punching head 4 and the lower punching slot 5, so as to realize the punching operation;

[0018] Preferably, the sizes, quantities and positions of the upper punching heads 4 on different upper punching blocks 2 are all different, that is, the upper punching heads 4 can be larger or smaller, and have a cylindrical, rectangular or regular hexagonal shape, and are located on both sides or in the middle of the upper punching block 2, so that different upper punching blocks 2 can be selected according to needs, so that different types of holes can be punched out on the electrical cabinet panel, which is convenient for meeting various punching requirements for the electrical cabinet panel; of course, it should be noted that after the size, quantity and position of the upper punching heads 4 are determined, the lower punching slots 5 on the lower punching block 3 should be set according to the actual situation of the upper punching heads 4, that is, the upper punching blocks 2 and the lower punching blocks 3 are set one by one, and the upper punching heads 4 and the lower punching slots 5 on the corresponding upper punching blocks 2 and the lower punching blocks 3 should be adapted to each other;

[0019] At the same time, the upper punching block 2 and the lower punching block 3 can be set larger to increase the contact area with the electrical cabinet panel, thereby helping to reduce the pressure on the electrical cabinet panel; secondly, the downward movement distance of the upper punching block 2 is certain, which is precisely controlled by the hydraulic cylinder to avoid the situation where the upper punching block 2 moves too far and causes excessive extrusion on the electrical cabinet panel;

[0020] In order to realize the installation and operation of the upper punching block 2 and the lower punching block 3, a horizontally arranged punching platform 6 is fixedly installed at the lower part of the frame 1, an upper punching seat 7 for cooperating with the punching platform 6 and a driving device 8 for driving the upper punching seat 7 to move up and down are installed at the upper part of the frame 1, a lower positioning groove for facilitating the installation of the lower punching block 3 is provided in the middle part of the top of the punching platform 6, an upper positioning groove for facilitating the installation of the upper punching block 2 is provided on the upper punching seat 7, and the upper punching block 2 is installed in the upper positioning groove by bolt connection; it is convenient to place the lower punching block 3 in the lower positioning groove, due to the weight of the lower punching block 3 itself and its cooperation with the lower positioning groove, bolts are not required for fixing, of course, if actually needed, bolts can also be used for fixing, the upper punching block 2 is installed in the upper positioning groove by bolts, and then the driving device 8 can be used to drive the upper punching seat 7 to drive the upper punching head 4 to move downward, cooperate with the lower punching block 3, and realize the punching operation of the electrical cabinet panel;

[0021] Preferably, the driving device 8 is a hydraulic cylinder, which is mounted on the frame 1. The upper punching seat 7 is fixedly connected to the piston rod end of the hydraulic cylinder. In order to prevent the upper punching seat 7 from deviation, a guide block 15 may be further provided on the upper punching seat 7. A guide rail 16 cooperating with the guide block 15 is also provided on the frame 1. The guide block 15 is arranged in the guide rail 16. When the punching platform 6 moves up and down, the guide block 15 cooperates with the guide rail 16 to guide the upper punching seat 7.

[0022] In order to prevent the electrical cabinet panel from moving during punching, a lower pressing block 10 is installed on the upper punching seat 7 around the upper positioning groove through a support spring 11, a guide rod 12 is installed on the lower pressing block 10, and a guide groove 13 cooperating with the guide rod 12 is provided on the upper punching seat 7. When the upper punching seat 7 moves downward, the lower pressing block 10 can contact the electrical cabinet panel first to press it down and fix it, and then the upper punching head 4 contacts the electrical cabinet panel again, and cooperates with the lower punching groove 5 to punch the electrical cabinet panel.

Some support blocks 14 are also designed on the punching platform 6 around the lower positioning groove. The main function of these support blocks 14 is to cooperate closely with the electrical cabinet panel to ensure the stability and accuracy of the punching process, which not only enhances the functionality of the punching platform 6 and the upper punching seat 7, but also effectively improves the processing quality of the punching of the electrical cabinet panel.

[0024] The actual working process of the electrical cabinet panel punching device provided by the utility model is:

[0025] First, according to the punching requirements of the electrical cabinet panel that needs to be punched, select the appropriate upper punching block 2 and lower punching block 3, and install the upper punching block 2 on the upper punching seat 7, and install the lower punching block 3 on the punching platform 6. Then, place the electrical cabinet panel flat on the lower punching block 3, and use the support block 14 to provide auxiliary support for it. Note that the position of the electrical cabinet panel must be accurately placed, that is, its punching position must be aligned with the upper punching head 4 on the upper punching block 2; then, turn on the driving device 8 to drive the upper punching seat 7 to move the upper punching block 2 downward until the upper punching head 4 on the upper punching block 2 contacts the position to be punched on the electrical cabinet panel, and penetrates the electrical cabinet panel and moves to the lower punching slot 5 on the lower punching block 3 to realize the punching operation on the electrical cabinet panel. During this period, the lower pressing block 10 will first contact the electrical cabinet panel, press it down and fix it, so as to prevent the electrical cabinet panel from moving during the punching operation and ensure the punching quality.
