[0036] The lubricating assembly comprises a liquid outlet pipe 21, a water collecting groove 22, a liquid storage tank 23 and a circulating pump 24, the liquid outlet pipe 21, the water collecting groove 22, the liquid storage tank 23 and the circulating pump 24 are fixedly connected with the rack 1, the liquid outlet pipe 21 is arranged above the limiting groove plate 6, the water collecting groove 22 is arranged on the lower side of the operation platform 4, the water collecting groove 22 is communicated with the liquid storage tank 23, the circulating pump 24 pumps the cooling lubricating liquid in the liquid storage tank 23 into the liquid outlet pipe 21, and the cooling lubricating liquid is sprayed to the wire drawing die 2 through the liquid outlet pipe 21 of the lubricating assembly.

[0037] The traction mechanism includes two rollers 7 and a geared motor 8. The two rollers 7 are rotatably mounted on the front of the mounting plate 3, and the geared motor 8 is fixedly mounted on the rear side of the mounting plate 3 and drives one of the rollers 7 to rotate.

[0038] A take-up roller 25 is rotatably mounted on one side of the frame 1. A geared motor 8 drives the take-up roller 25 to rotate via belt drive. A wire support seat 26 is rotatably mounted on the side of the frame 1 away from the take-up roller 25. The processed wire 9 is sleeved on the wire support seat 26, and the front end of the processed wire 9 is fixed to the take-up roller 25. At the same time, the processed wire 9 is wound around two pulleys 7, and the processed wire 9 passes through the die hole of the drawing die 2. The processed wire 9 is wound around the two pulleys 7 in the following manner: Figure 6 As shown, the winding drum 25 and the pulley 7 work together to move the traction processing wire 9. The pulley 7 rotates clockwise to guide the processing wire 9 to move in the first direction, as shown in the diagram. Figure 8 , Figure 9 As shown, the first direction refers to the direction indicated by F1, or the forward movement of the processed wire 9;

[0039] The operating platform 4 is equipped with a tensioning component, which controls the processing wire 9 to cycle between a tensioned state and a non-tensioned state. Guided by the tensioning component, a localized area of ​​the non-tensioned processing wire 9 moves in a second direction, such as... Figure 9 As shown, the second direction refers to the direction shown in F2, or the reverse movement of the processed wire 9, which is opposite to the first and second directions.

[0040] In this embodiment, the tensioning assembly includes a first eccentric wheel 10, a second eccentric wheel 11, and a drive mechanism. The first eccentric wheel 10 and the second eccentric wheel 11 are rotatably mounted on the upper surface of the operating platform 4. The drive mechanism is located inside the operating platform 4 and drives the first eccentric wheel 10 and the second eccentric wheel 11 to rotate synchronously.

[0041] The operating platform 4 is rotatably mounted with a first limiting double shaft 12 and a second limiting double shaft 13. Both the first limiting double shaft 12 and the second limiting double shaft 13 refer to two vertically arranged rotating shafts. The first eccentric wheel 10 and the first limiting double shaft 12 form a group, and the processing wire 9 passes through the area between the first eccentric wheel 10 and the first limiting double shaft 12. The second eccentric wheel 11 and the second limiting double shaft 13 form a group, and the processing wire 9 passes through the area between the second eccentric wheel 11 and the second limiting double shaft 13. When the first eccentric wheel 10 rotates closer to the first limiting double shaft 12, the second eccentric wheel 11 rotates away from the second limiting double shaft 13. Figure 5 As shown.

[0042] Specifically, when the first eccentric wheel 10 rotates close to the first limiting double shaft 12, the first eccentric wheel 10 extrudes the processed wire 9, and the processed wire 9 located within the first limiting double shaft 12 forms a first bent portion 14. At this time, the processed wire 9 is in a tensioned state, such as... Figure 8 As shown.

[0043] When the second eccentric wheel 11 rotates close to the second limiting double shaft 13, the second eccentric wheel 11 extrudes the processing wire 9, and the processing wire 9 located within the second limiting double shaft 13 forms a second curved portion 15. At this time, the processing wire 9 is in a non-tensioned state, the second curved portion 15 appears, the first curved portion 14 disappears, and the processing wire 9 in the local area moves in the second direction.

[0044] It should be noted that the reference Figure 9 The processed wire 9 is a continuous linear material, and the processed wire 9 in the aforementioned local area refers to the area between the first curved portion 14 and the second curved portion 15.

[0045] For ease of understanding, assume that the moving speed of the processed wire 9, which is pulled in the positive direction by the take-up roller 25, is 0. Figure 8 As shown, after the first eccentric wheel 10 extrudes the wire 9 and the first bend 14 appears, as... Figure 9 As shown, during the extrusion process of the wire 9 by the second eccentric wheel 11, the length of the first curved portion 14 disappears, and the length of the second curved portion 15 appears near the second eccentric wheel 11. The processed wire 9 in the local area moves in the direction of F2. At this time, the wire drawing die 2 remains stationary, and the relative displacement between the processed wire 9 and the wire drawing die 2 is as follows: Figure 10 The image below is shown in the figure.

[0046] In reality, the take-up roller 25 takes up the processed wire 9, which moves in the direction of F1. A portion of the length of the first bending section 14 compensates for the displacement in the direction of F1, and another portion of the length of the first bending section 14 compensates for the displacement in the direction of F2. That is, the processed wire 9 and the drawing die 2 produce a... Figure 10 The relative displacement is shown in the figure below.

[0047] In this embodiment, as Figure 4As shown, the drive mechanism includes a servo motor 16, a drive shaft 17, a first bevel gear 18, a second bevel gear 19, a synchronous pulley 20, and a synchronous belt 27. The drive shaft 17 is rotatably mounted inside the operating platform 4. The first bevel gear 18 is fixedly mounted on the drive shaft 17. The second bevel gear 19 is fixedly mounted on the bottom end of the central shaft of the first eccentric wheel 10. The first bevel gear 18 and the second bevel gear 19 mesh and drive each other. The central shafts of the first eccentric wheel 10 and the second eccentric wheel 11 are both fixedly mounted with synchronous pulleys 20. The two synchronous pulleys 20 are driven by the synchronous belt 27. The servo motor 16 is fixedly mounted on the rear side of the mounting plate 3. The servo motor 16 drives the drive shaft 17 to rotate, and drives multiple sets of first eccentric wheels 10 and second eccentric wheels 11 to rotate synchronously through the drive mechanism.

[0048] refer to Figure 10 During the wire drawing process, the processed wire 9 is pulled in the direction of F1, passing through the die hole of the drawing die 2. The die hole squeezes the processed wire 9, reducing its cross-sectional area. At this time, a certain biting force is generated between the die hole opening of the drawing die 2 and the processed wire 9, making it difficult for debris generated by squeezing and friction to fall off. By setting a tensioning component, the tensioning component controls the processed wire 9 to cycle between a tensioned state and an untensioned state. In the untensioned state, a local area of ​​the processed wire 9 moves in the direction of F2, and the processed wire 9 and the drawing die 2 generate a biting force. Figure 10 The relative displacement shown in the figure below releases the biting force of the die hole extruding the wire 9. The lubricant can flush away the debris aggregated on the surface of the wire 9, making it easier for the debris blocking the die hole to fall off, thus preventing the wire from breaking or being scratched due to debris blockage.

[0049] It should be noted here that the die hole size of each wire drawing die 2 gradually decreases, such as... Figure 10 As shown, the force that pulls the processing wire 9 to move in the direction of F1 is much greater than the force that pulls the processing wire 9 to move in the direction of F2 because it has to overcome the resistance of the reduced diameter of the processing wire 9. Therefore, the processing wire 9 in the local area moves in the direction of F2.

[0050] The wire drawing device proposed in this invention provides tension force to the processed wire 9 by setting up a first eccentric wheel 10 and a second eccentric wheel 11 that can rotate cyclically. This causes the first curved part 14 and the second curved part 15 on the processed wire 9 to increase and decrease in opposite directions, realizing the function of local areas of the processed wire 9 moving in the opposite direction. This facilitates the cleaning of blockage debris and ensures that the processed wire 9 is conveyed in the positive direction as a whole, realizing continuous wire drawing and meeting the requirement that the wire drawing speed can be adjusted as needed.

[0051] By setting the wire drawing die 2 with a conical hole structure with mirror symmetry at both ends of the die hole, the wire 9 moving in both forward and reverse directions is uniformly extruded. When the wire 9 moves in the reverse direction, the part of the wire 9 that is extruded by the die hole separates from the wire drawing die 2, which increases the number of lubrication and cooling cycles and improves the surface quality of the wire. When the wire 9 moves from the reverse direction to the forward direction, the part of the wire 9 that is extruded by the die hole passes through the wire drawing die 2 again for secondary extrusion, which reduces the expansion deformation of the material after wire drawing and ensures the stability of the wire size.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
