An electric push rod 401 on the frame 3, a bearing plate 402 is installed on the lower side of the electric push rod 401, a drilling device 403 is installed on the lower end of the bearing plate 402, a detachable cleaning component 5 is installed on the outer side of the drilling device 403 on the bearing plate 402, and the detachable cleaning component 5 includes a cleaning scraper 502 installed on the outer side of the drilling device 403, and a discharge cleaning component 6 is installed on the inner side of the two plate clamping devices 8 on the support frame 3, and the discharge cleaning component 6 includes a cleaning brush 603 installed above the central waste guide groove;

[0020] By adopting the above technical scheme, the two-axis moving device 7 is composed of an X-axis moving component and a Y-axis moving component. The X-axis moving component is composed of a driving motor, a screw rod, a wire sleeve, a moving frame installed on the side of the wire sleeve and a guide rail guiding the moving frame. The Y-axis moving component is composed of a pushing cylinder installed on the top of the wire sleeve, a mounting frame, and a slider installed at the bottom of the mounting frame and adapted to the moving frame. The plate clamping device 8 is composed of a cylinder and a clamping plate. The two-axis moving device 7 drives the plate clamping device 8 to move horizontally, driving the plate and the drilling equipment 403 to undergo relative displacement, completing the opening of holes at different positions. During the opening process, the lower surface of the cleaning scraper 502 is fitted with the upper surface of the plate to concentrate the debris on the upper surface of the plate on the inner side of the cleaning scraper 502 to prevent waste debris from splashing to other areas and affecting the opening accuracy of other positions of the plate. In conjunction with the blanking operation, the cleaning brush 603 is used for unified cleaning without the need for subsequent cleaning.

[0021] Reference Figure 3 A guide rod 404 is installed on the outer side of the electric push rod 401 on the bearing plate 402, and the upper end of the guide rod 404 passes through the support frame 3 and is slidably connected to the support frame 3;

[0022] By adopting the above technical solution, the guide rod 404 is used to guide the supporting plate 402 up and down, so as to prevent the supporting plate 402 from deflecting.

[0023] Reference Figure 2 , mounting clamps 501 are installed on both sides of the cleaning scraper 502, the mounting clamps 501 are fixedly connected to the bearing plate 402, a plurality of threaded holes are provided on the mounting clamps 501, and fixing bolts 503 are installed in the threaded holes, and the ends of the fixing bolts 503 pass through the corresponding cleaning scraper 502 and are slidably connected to the cleaning scraper 502;

[0024] By adopting the above technical solution, the cleaning scraper 502 and the mounting clamp plate 501 are locked by the fixing bolts 503, so as to facilitate the subsequent disassembly and replacement, as well as the maintenance of the internal drilling equipment 403.

[0025] Reference Figure 3 The cleaning scraper 502 is made of an elastic transparent material, and the lower end of the cleaning scraper 502 is bent toward a side away from the drilling device 403;

[0026] By adopting the above technical solution, the cleaning scraper 502 can be bent outward when the drilling device 403 is drilling, so as to avoid affecting the processing and facilitate observation of the internal situation of the cleaning scraper 502.

The two connecting seats 601 are fixedly connected to the support frame 3, and the lower end of the cleaning brush 603 is flush with the upper surface of the two-axis moving device 7;

[0028] By adopting the above technical solution, when the unloaded plate passes through the cleaning brush 603, the cleaning brush 603 can block the waste chips on the upper surface of the plate and guide the intercepted chips on the upper surface of the plate into the central waste guide groove without subsequent processing.

[0029] The implementation principle of a hole-punching device for metal parts of household appliances according to an embodiment of the present application is as follows: during the processing, the two-axis moving device 7 drives the plate clamping device 8 to move horizontally, causing the plate and the drilling device 403 to undergo relative displacement, thereby completing the hole-punching at different positions. During the hole-punching process, the lower surface of the cleaning scraper 502 is fitted with the upper surface of the plate to concentrate the debris on the upper surface of the plate on the inner side of the cleaning scraper 502, thereby preventing waste debris from splashing to other areas and affecting the hole-punching accuracy at other positions of the plate. In conjunction with the material unloading operation, the cleaning brush 603 is used for unified cleaning without the need for subsequent cleaning.
