[0002] The EDM perforator is a machine tool that uses the principle of electric spark discharge to process metal. It is usually used for precision perforation of metal workpieces, especially for processing hard and high-strength metal materials. The working principle of the EDM perforator is to generate electric spark discharge on the surface of the workpiece, and use the high temperature and high energy of the electric spark to melt and corrode the metal, thereby achieving perforation of the workpiece. This processing method is suitable for hole processing that requires high precision, complex shapes or special materials, such as mold manufacturing, aerospace parts processing and other fields. The EDM perforator is usually composed of a control system, electrodes, a workbench, a power supply and other parts.

During the processing, the worker controls the pallet and moves the product to be punched through the pallet, which makes it easy to cause movement deviation when the perforated product is moved, thereby causing damage to the component processing, affecting the component punching processing yield and work efficiency.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2, the utility model provides an embodiment: an electric spark punching machine with a guiding mechanism, comprising a workbench 1, a servo motor 3 is fixedly connected to the front end of the inner wall of the workbench 1, a threaded rod 4 is fixedly connected to the output end of the servo motor 3, a conveying plate 5 is threadedly connected to the outer wall of the threaded rod 4, a vertical plate 7 is fixedly connected to the right side of the conveying plate 5, an electric telescopic rod 8 is fixedly connected to the inner top wall of the vertical plate 7, a fixed plate 9 is fixedly connected to the output end of the electric telescopic rod 8, a rubber pad 10 is fixedly connected to the bottom wall of the fixed plate 9, a sliding column 11 is fixedly connected to the rear end of the right side of the inner wall of the workbench 1, the middle part of the sliding column 11 passes through the rear side of the inner wall of the conveying plate 5, a fixing piece 12 is fixedly connected to the left side of the top wall of the workbench 1, and hydraulic rods 13 are fixedly connected to the front and rear sides of the inner top wall of the fixing piece 12, and the output ends of the two hydraulic rods 13 are fixedly connected to displacement plates 14, and a punching device 15 is fixedly installed on the bottom wall of the displacement plate 14, and a heat dissipation mechanism 2 is provided on the bottom wall of the workbench 1;

[0030] Specifically, by starting the electric telescopic rod 8, the fixed plate 9 is used to fix the parts to ensure that the parts maintain a stable position during the punching process, and the servo motor 3 is started to drive the threaded rod 4 to start rotating. Under the limited rotation of the sliding column 11, the conveying plate 5 will not rotate with the threaded rod 4, but will be smoothly displaced along a preset path. When the conveying plate 5 reaches the specified position, the two hydraulic rods 13 are activated. They push the displacement plate 14 to drive the punching device 15 to perform precise displacement, thereby completing the punching work. This punching method not only improves the accuracy of the punching, but also avoids component processing damage caused by movement offset.

[0031] Reference Figure 1 and Figure 3 The heat dissipation mechanism 2 includes a protective shell 201, the top wall of the protective shell 201 is fixedly installed on the right side of the bottom wall of the workbench 1, a filter plate 202 is fixedly connected to the right side of the protective shell 201, a blower 203 is fixedly connected and installed in the middle of the right side of the bottom wall of the workbench 1, the output end of the blower 203 is connected with a delivery pipe 204, and the top ends of the two delivery pipes 204 are both connected with a heat dissipation nozzle 206; the top ends of the outer walls of the two delivery pipes 204 are fixedly installed with rubber rings 205, and the outer walls of the two rubber rings 205 are fixedly connected to the outer sides of the corresponding heat dissipation nozzles 206;

[0032] Specifically, the airflow filtered by the filter plate 202 is extracted by starting the blower 203. This ensures that large particles do not enter the interior of the blower 203. This not only prolongs the service life of the blower 203 and reduces maintenance costs, but also improves the stability of the overall equipment. The filtered airflow passes through the delivery pipe 204, passes through the heat dissipation nozzle 206, and finally performs heat dissipation and cooling work on the perforated parts.

[0033] Reference Figure 2The front and rear sides of the displacement plate 14 are fixedly connected with sliders 16, the front and rear sides of the inner wall of the fixing member 12 are provided with slide grooves 17, and the two sliders 16 are slidably connected with the corresponding slide grooves 17 on the far sides; the top wall of the conveying plate 5 is provided with a fixing groove 6, and the middle part of the right side of the inner wall of the workbench 1 is fixedly connected with a limiting rod 18; the four corners of the bottom wall of the workbench 1 are fixedly connected with support columns 21;

[0034] Specifically, the two sliders 16 are slidably connected through the corresponding sliding grooves 17 on the opposite sides, so that the displacement direction of the displacement plate 14 can be limited when it is displaced, the fixing groove 6 allows the parts to be placed, and the limiting rod 18 prevents the conveying plate 5 from excessive displacement and causing damage to the servo motor 3.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The front side of the fixing member 12 is fixedly connected with a control switch 19, and the control switch 19 is electrically connected with the blower 203, the servo motor 3 and the hydraulic rod 13 respectively; the front side of the control switch 19 is provided with a protective shell 20, and the rear side of the protective shell 20 is rotatably connected with the front side of the fixing member 12 through a hinge;

[0036] Specifically, the control switch 19 is electrically connected to the blower 203, the servo motor 3 and the hydraulic rod 13 respectively, so that the control switch 19 can complete the opening and closing of the device, and the protective shell 20 can protect the control switch 19 and prevent accidental touch.

[0037] Working principle: before starting the perforation, the parts are placed on the top wall of the conveying plate 5, and the electric telescopic rod 8 is started so that the fixing plate 9 can fix the parts. The servo motor 3 is started so that the threaded rod 4 starts to rotate. Under the limited rotation of the sliding column 11, the conveying plate 5 will not rotate along with the threaded rod 4, so that the conveying plate 5 completes the displacement guiding work. By starting the two hydraulic rods 13, the displacement plate 14 drives the perforating device 15 to move, so that the perforation work is performed, thereby improving the perforation accuracy, avoiding the situation that the movement offset and the damage to the component processing are easily caused, thereby improving the qualified rate and work efficiency, and by starting the blower 203, the airflow filtered by the filter plate 202 can be extracted, so that larger particles will not enter the interior of the blower 203, thereby reducing the possibility of damage to the blower 203, and then the airflow passes through the conveying pipe 204 and the heat dissipation nozzle 206 to cool the perforated parts, thereby reducing the situation that the temperature of the parts is too high after perforation.
