Two vertical plates 2 are connected to the top of the base 1. A top plate 3 is connected to the top of the two vertical plates 2. A cross slide 4 is connected to the bottom of the top plate 3. A hydraulic cylinder 5 is connected to the bottom of the cross slide 4. A dust cover 6 is connected to the bottom of the hydraulic cylinder 5. A first rotating shaft 7 is connected inside the dust cover 6. A connecting cylinder 8 is connected to the outer wall of the first rotating shaft 7. Three sets of fixing frames 9 are connected to the outer wall of the connecting cylinder 8. A second rotating shaft 10 is installed inside each set of fixing frames 9. A wire drawing wheel 11 is connected to the outer wall of the dust cover 6. A support plate 12 is connected to the front side of the dust cover 6. A first motor 13 is connected to the top of the support plate 12. A worm gear 14 is connected to the output end of the first motor 13. The front end of the first rotating shaft 7 passes through the dust cover 6 and is connected to a worm wheel 15. The worm wheel 15 meshes with the worm gear 14. A fixing plate 16 is connected to the bottom of the dust cover 6. A second motor 17 is connected to the side wall of the fixing plate 16. A drive gear 18 is connected to the output end of the second motor 17. The rear ends of multiple second rotating shafts 10 are all connected to... There is a driven gear 19, which is located at the bottom and meshes with the driving gear 18. When other drawing wheels 11 are needed, the first motor 13 drives the worm gear 14 to rotate, the worm gear 14 drives the worm wheel 15 to rotate, the worm wheel 15 drives the first rotating shaft 7 to rotate, the first rotating shaft 7 drives the connecting cylinder 8 to rotate, the connecting cylinder 8 drives multiple sets of fixing frames 9 to rotate, and the fixing frames 9 drive the drawing wheels 11 connected to them to rotate, so that the drawing wheel 11 to be used can be rotated to the bottom, which can facilitate and quickly adjust the drawing wheel 11. In the process of rotating the wire drawing wheel 11, the driven gear 19 on the rear side of the wire drawing wheel 11 being used disengages from the driving gear 18, and the driven gear 19 on the rear side of the other wire drawing wheel 11 being used gradually engages with the driving gear 18. By using the second motor 17 to drive the driving gear 18 to rotate, the driving gear 18 drives the driven gear 19 that is engaged with it to rotate, and the driven gear 19 drives the wire drawing wheel 11 located on the bottom side to rotate, so that the wire drawing wheel 11 can be used to perform wire drawing treatment on the surface of the chain accessories.

[0020] A dust collection box 20 is connected to the top of the base 1. A dust exhaust fan 21 is connected to the right side of the dust collection box 20. A dust extraction pipe 22 is connected to the top of the dust collection box 20. The other end of the dust extraction pipe 22 is connected to the dust cover 6. By using the dust exhaust fan 21 to extract dust, the dust generated when the drawing wheel 11 is drawing the wire is drawn into the dust extraction pipe 22, and the dust is collected by the dust collection box 20.

[0021] The top of the base 1 is connected to a placement platform 23. The top of the placement platform 23 has a groove, and a bidirectional lead screw 24 is rotatably installed in the groove. Two moving blocks 25 are connected to the outer wall of the bidirectional lead screw 24. The top of each moving block 25 is connected to a clamping plate 26. The chain accessory that needs to be pulled is placed between the two clamping plates 26. By rotating the turntable 27, the turntable 27 drives the bidirectional lead screw 24 to rotate.

[0024] Working principle of this utility model:

[0025] The chain component requiring wire drawing is placed between two clamping plates 26. By rotating the turntable 27, the turntable 27 drives the bidirectional lead screw 24 to rotate. The bidirectional lead screw 24 drives two moving blocks 25 to move relative to each other. The moving blocks 25 pull the clamping plates 26, thus clamping the chain component using the two clamping plates 26. The first motor 13 drives the worm gear 14 to rotate, which in turn drives the worm wheel 15 to rotate. The worm wheel 15 drives the first rotating shaft 7 to rotate, which in turn drives the connecting cylinder 8 to rotate. The connecting cylinder 8 drives multiple sets of fixing frames 9 to rotate, and the fixing frames 9 drive the wire drawing wheels 11 connected to them to rotate. The wire drawing wheel 11 to be used is rotated to the bottom, allowing for convenient and quick replacement of the wire drawing wheel 11. During the rotation of the wire drawing wheel 11, the driven gear 19 on the rear side of the wire drawing wheel 11 being used disengages from the driving gear 18, and the driven gear 19 on the rear side of the other wire drawing wheel 11 being used gradually engages with the driving gear 18. By using the second motor 17 to drive the driving gear 18 to rotate, the driving gear 18 drives the driven gear 19 that it is engaged with to rotate, and the driven gear 19 drives the wire drawing wheel 11 located on the bottom side to rotate. Thus, the wire drawing wheel 11 can be used to perform wire drawing on the surface of the chain accessories. By using the dust extraction fan 21 to extract dust, the dust generated when the wire drawing wheel 11 is drawing wire is drawn into the dust extraction pipe 22, and the dust is collected by the dust collection box 20.
