Vertical plates 18 are fixedly and symmetrically installed on the top of the wire cutting moving bed 15. A valve cabinet 30 is horizontally installed between the vertical plates 18. The molybdenum wire 14 is arranged through the processing gap 21 between the valve cabinets 10. A conveyor belt 24 is horizontally installed between the wire cutting moving bed 15 and the vertical plates 18. A chip collection cart 27 is placed at the end of the conveyor belt 24.
[0025] The top of the working fluid tank 1 is equipped with a slide rail 3 and a first motor 6. The top of the slide rail 3 is equipped with a tray seat 4. The wire storage drum 5 is rotatably mounted on the tray seat 4, and the first motor 6 and the tray seat 4 are connected in a transmission. The side of the tray seat 4 is equipped with a second motor 7, and the second motor 7 and the wire storage drum 5 are connected in a cyclic transmission. The top of the wire storage drum 5 is also equipped with a first protective cover 9.
[0026] A column 10 is vertically installed on the top of the working fluid tank 1. The upper wire frame 11 and the lower wire frame 12 are horizontally and fixedly connected to the column 10. The two ends of the upper wire frame 11 and the lower wire frame 12 are rotatably installed with a second rotating shaft 13, and the molybdenum wires 14 are all laid on the second rotating shaft 13.
[0027] The top of the wire EDM moving bed 15 is equipped with multiple brackets 16. The top of the brackets 16 is horizontally equipped with a base plate 17. The vertical plates 18 are all vertically installed on the top of the base plate 17. The top of the base plate 17 is vertically equipped with multiple positioning shafts 19. Multiple locking pins 20 are installed on the vertical plates 18. The valve cabinets 30 are all fitted on the positioning shafts 19 and fastened by the locking pins 20.
[0028] The top of the wire EDM moving bed 15 is equipped with a support 23 and a third motor 26. The conveyor belt 24 is fixedly installed on the top of the support 23 and is connected to the third motor 26. A baffle 25 is also installed on the side of the conveyor belt 24 near the bottom plate 17.

[0030] A material level sensor 28 is installed on the side wall of the scrap collection vehicle 27, and a vibration motor 29 is also installed at the bottom of the scrap collection vehicle 27.
[0031] In practical application, the following steps are taken: First, check that the working fluid tank 1, control cabinet 2, first motor 6, wire storage drum 5, upper wire frame 11, lower wire frame 12, and wire cutting moving bed 15 of the equipment are properly installed. Then, a 0.28mm molybdenum wire 14 is tightly wound around the wire storage drum 5 and extended and erected through the upper wire frame 11 and lower wire frame 12. Then, lock both ends of the molybdenum wire 14 at the wire storage drum 5 to ensure that the wire storage drum 5 can move back and forth under the drive of the first motor 6 and the second motor 7 to rotate the wire. Then, fix the base plate 17, upright plate 18, positioning shaft 19, and locking pin 20 on the top of the wire cutting moving bed 15, and install four sets of valve cabinets 30 on the positioning shaft 19 and lock them with locking pins 20 so that the molybdenum wire 14 is located at the center of the processing gap 21 formed between the valve cabinets 30. Finally, install and arrange the conveyor belt 24, three motors 26, and iron chip collection cart 27 properly. The processing equipment is then started, causing the molybdenum wire 14 to rotate continuously with the wire storage drum 5. Following a preset movement trajectory within the control cabinet 2, it drives the wire cutting moving bed 15 and the four clamped valve cabinets 30 to move horizontally, forming an "∞" trajectory. This causes relative displacement of the molybdenum wire 14. Through pulsed sparks and discharges, first counterclockwise and then clockwise, the edge of the valve cabinet 30 is cut into the required semi-circular irregular hole 31. The cut iron filings and other debris fall onto the conveyor belt 24 and are transported to the iron filings collection cart 27, achieving... The timely transfer and collection of the material after processing and cutting ensures the overall operation and cutting of the equipment. With the control cabinet 2 preset with the processing trajectory of the valve cabinet 30 irregular hole 31, as the wire cutting moving bed 15 moves along the processing trajectory, the molybdenum wire 14 cuts the edge of the valve cabinet 30 into the required irregular hole 31 structure. This realizes convenient and efficient cutting of the irregular hole 31 of the heat-treated hard valve cabinet 30, effectively improving the overall processing quality and efficiency of the irregular hole 31 of the valve cabinet 30. Therefore, the equipment has good practicality.
