[0032] During use, through the cooperation between the wire feeding assembly 4 and the wire winding assembly 3, it is convenient to feed wire to the wire-cut EDM machine. Moreover, the pressing assembly 14 in the installation groove 13 is convenient for pressing the molybdenum wire, and the wire reel 12 is provided to facilitate the winding of the molybdenum wire.

[0033] Refer to Figure 4, the pressing assembly 14 includes a driving frame 16 slidably connected to the inner wall of the installation groove 13, and a pressing wheel 17 is rotatably connected to the outer walls on both sides of the driving frame 16. The pressing wheel 17 on the driving frame 16 directly contacts the molybdenum wire, so as to facilitate the precise winding of the molybdenum wire on the wire storage cylinder 7.

[0034] Refer to Figure 4 and Figure 5 , a tensioning assembly 15 connected to the driving frame 16 is installed on the bottom inner wall of the installation groove 13. The tensioning assembly 15 includes a tensioning seat 18 fixedly connected to the bottom inner wall of the installation groove 13. The arrangement of the tensioning assembly 15 facilitates driving the driving frame 16 to continuously move downward, and further enables the pressing wheel 17 to contact the molybdenum wire.

[0035] Refer to Figure 5 , an adjusting seat 21 is slidably connected to the inner wall of the tensioning seat 18, and a connecting column 22 is fixedly connected to the outer wall of the top of the adjusting seat 21. One end of the connecting column 22 is fixedly connected to the driving frame 16. Driving the connecting column 22 to move through the adjusting seat 21 facilitates directly driving the driving frame 16 to move.

[0036] Refer to Figure 5 , two symmetrically arranged fixing rods 19 are fixedly connected to the bottom inner wall of the tensioning seat 18, and springs 20 are sleeved on the outer walls of the fixing rods 19. The adjusting seat 21 is slidably connected to the outer walls of the two fixing rods 19. The arrangement of the fixing rods 19 facilitates restricting the sliding trajectory of the adjusting seat 21, and the arrangement of the springs 20 facilitates driving the adjusting seat 21 to move downward, and further cooperates with the driving frame 16 to drive the pressing wheel 17 to press the molybdenum wire.

[0040] The implementation principle of this application is as follows: When in use, when it is necessary to wind the wire on the wire storage cylinder 7, the electric slide rail 5 directly drives the drive seat 6 to slide out, and then wind the molybdenum wire on the wire storage cylinder 7 from the wire spool 12. Then start the wire winding motor 10, and the wire winding motor 10 drives the wire storage cylinder 7 to rotate through the belt 9, so as to directly wind the molybdenum wire. While winding, the electric slide rail 5 drives the drive seat 6 to retract into the rectangular groove 2, so as to facilitate the uniform winding of the molybdenum wire on the outer wall of the wire storage cylinder 7. While the molybdenum wire is being wound, the spring 20 directly pushes the adjusting seat 21 downward. When the adjusting seat 21 moves downward, it directly pulls the pressing wheel 17 to press on the molybdenum wire through the connecting column 22, which is convenient for tensioning the molybdenum wire.
