Description

Technical Field

[0001] This utility model relates to the field of wire drawing equipment technology, and in particular to a pulley-type wire drawing machine. Background Technology

[0002] Metal wire drawing machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wires or bars produced by steel manufacturers and transported to standard parts and other metal product manufacturers, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wires or bars meet the raw material processing requirements for the production of standard parts and other metal products.

[0003] There are several types of wire drawing machines commonly used in the industry, one of which is the pulley-type wire drawing machine. During the operation of a pulley-type wire drawing machine, lubricating powder is needed to lubricate the steel wire, thereby reducing the friction between the steel wire and the die, and thus extending the die's service life. Currently used pulley-type wire drawing machines lack end caps for the lubricating powder tank, making it prone to dust accumulation. Furthermore, the steel wire passes directly through the lubricating powder, making it difficult for the powder to adhere to the wire surface, thus compromising lubrication effectiveness.

[0004] To address the problems in the existing technology, a pulley-type wire drawing machine is provided. Summary of the Invention

[0005] In view of this, this utility model proposes a pulley-type wire drawing machine to solve the existing problems.

[0006] The technical solution of this utility model is achieved as follows: This utility model provides a pulley-type wire drawing machine, including a base, a drum, a gearbox, a drive motor, a mold box, a first pulley assembly, and a second pulley assembly, wherein...

[0007] A drum is provided at the upper end of the base;

[0008] The lower end of the base has a receiving space, and the gearbox and drive motor are located in the receiving space;

[0009] A mold box is provided on one side of the base;

[0010] The mold box has a first pulley assembly on one side and a second pulley assembly on the other side;

[0011] The mold box is divided into a first space and a second space by a partition in the middle. The upper end of the first space is connected to a cover plate by a pivot. The upper end of the cover plate, which is opposite to the pivot, is provided with a compression spring. A support plate is provided on the upper side of the partition plate. A screw is vertically provided on the support plate. A pressure cap is provided on the upper end of the screw. A mold sleeve is provided on the middle side of the partition plate. A wire drawing mold is detachably provided in the mold sleeve. A through hole is opened at the upper end of the mold sleeve and is located directly below the screw. A first guide hole is provided between the first space and the second space. A second guide hole is provided on the outside of the first space. A third guide hole is provided on the outside of the second space.

[0012] Furthermore, preferably, the second pulley assembly includes a vertical pole, which is vertically disposed on the upper surface of the base, and a horizontal bar is provided at the upper end of the vertical pole, with a second fixed pulley provided at one end of the horizontal bar.

[0013] Furthermore, preferably, the upper surface of the cover plate is provided with a counterweight, and the counterweight is located below the compression spring, and the lower end of the compression spring is fixedly connected to the counterweight.

[0014] Furthermore, preferably, a plug is detachably provided at the bottom of the first space.

[0015] Furthermore, preferably, a guide portion is provided at the outlet of the third guide hole.

[0016] Furthermore, preferably, the first pulley assembly includes a bracket located on one side of the second guide hole, and a first fixed pulley is provided at the upper end of the bracket.

[0017] The present invention has the following advantages over the prior art:

[0018] (1) The pulley-type wire drawing machine disclosed in this utility model drives the screw to be screwed into the through hole by rotating the pressure cap. Then, the lower end of the screw is pressed against the wire drawing die, which can prevent the wire drawing die from sliding during the wire drawing process.

[0019] (2) The pressure cap is pressed against the upper end of the pressure spring. The pressure spring is compressed and transmits the pressure to the upper end of the cover plate. In turn, the cover plate compacts the lubricating powder more. Therefore, when the steel wire passes through the lubricating powder, it can ensure that the lubricating powder adheres better to the steel wire. At the same time, the pressure spring has a reaction force on the pressure cap, which can prevent the pressure cap from causing the screw to flip.

[0020] (3) When too much rust and other impurities remain in the lubricating powder in the first space during the wire drawing process, it is necessary to replace it with new lubricating powder. At this time, the plug can be opened to allow the lubricating powder to be discharged from the plug, making the operation process faster. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] like Figure 1 As shown, combined with Figure 2-5 This utility model discloses a pulley-type wire drawing machine, including a base 1, a drum 2, a gearbox 3, a drive motor 4, a mold box 5, a first pulley assembly 6, and a second pulley assembly 7, wherein...

[0031] A drum 2 is provided at the upper end of the base 1;

[0032] The lower end of the base 1 is provided with a receiving space, and a gearbox 3 and a drive motor 4 are provided in the receiving space;

[0033] A mold box 5 is provided on one side of the base 1;

[0034] The mold box 5 has a first pulley assembly 6 on one side and a second pulley assembly 7 on the other side;

[0035] The mold box 5 is divided into a first space 51 and a second space 52 by a partition 8 in the middle. The upper end of the first space 51 is connected to a cover plate 9 by a rotating shaft. The upper end of the cover plate 9, which is opposite to the rotating shaft, is provided with a compression spring 10. A support plate 11 is provided on one side of the upper end of the partition 8. A screw 12 is vertically provided on the support plate 11. A pressure cap 13 is provided on the upper end of the screw 12. A mold sleeve 22 is provided on one side of the middle of the partition 8. A wire drawing mold 14 is detachably provided in the mold sleeve 22. A through hole 15 is opened at the upper end of the mold sleeve 22 and is located directly below the screw 12. A first guide hole 16 is provided between the first space 51 and the second space 52. A second guide hole 17 is provided on the outside of the first space 51. A third guide hole 18 is provided on the outside of the second space 52. First, a suitable wire drawing die 14 is installed into the die sleeve 22. Then, the steel wire to be drawn is passed through the second guide hole 17, the first guide hole 16, and the third guide hole 18 in sequence, and the end of the steel wire is fixed to the drum 2. Next, the first space 51 is filled with lubricating powder, and the cover plate 9 is pressed on the lubricating powder. At this time, by rotating the pressure cap 13, the screw 12 is driven into the through hole 15. Then, the lower end of the screw 12 is pressed against the wire drawing die 14, which can prevent the wire drawing die 14 from slipping during the wire drawing process. When the screw 12 is pressed against the wire drawing die 14, the pressure cap 13 is pressed against the upper end of the pressure spring 10. The pressure spring 10 is compressed and the pressure is transmitted to the upper end of the cover plate 9. Then, the cover plate 9 presses the lubricating powder more compactly. Therefore, when the steel wire passes through the lubricating powder, it can ensure that the lubricating powder adheres better to the steel wire. At the same time, the compression spring 10 exerts a reaction force on the pressure cap 13, which can prevent the pressure cap 13 from causing the screw 12 to flip.

[0036] In this embodiment, the second pulley assembly 7 includes a vertical rod 71, which is vertically disposed on the upper surface of the base 1. A horizontal bar 72 is provided at the upper end of the vertical rod 71, and a second fixed pulley 73 is provided at one end of the horizontal bar 72. After the steel wire is drawn, it wraps around the outer periphery of the drum 2, thus completing one drawing process. Since the drawing effect cannot be guaranteed by one drawing process, multiple drawing processes are required. In this case, the steel wire wrapped around the outer periphery of the drum 2 is passed around the second fixed pulley 73 and then transferred to the next drawing machine, thus completing the second drawing process.

[0037] In this embodiment, a counterweight 19 is provided on the upper surface of the cover plate 9, and the counterweight 19 is located below the compression spring 10, with the lower end of the compression spring 10 fixedly connected to the counterweight 19. To enhance the compaction effect on the lubricating powder and thus ensure the adhesion of the lubricating powder to the outside of the steel wire, a counterweight 19 is provided at one end of the upper surface of the cover plate 9.

[0038] In this embodiment, a plug 20 is detachably provided at the bottom of the first space 51. When the lubricating powder in the first space 51 accumulates too much rust and other impurities during the wire drawing process, it needs to be replaced with new lubricating powder. At this time, the plug 20 can be opened to allow the lubricating powder to be discharged from the plug 20, making the operation process faster.

[0039] In this embodiment, a guide portion 21 is provided at the outlet of the third guide hole 18. After the steel wire passes through the third guide hole 18, the guide portion 21 ensures that the guiding part of the steel wire is longer, thus minimizing the possibility of the steel wire bending.

[0040] In this embodiment, the first pulley assembly 6 includes a bracket 61 located on one side of the second guide hole 17, and a first fixed pulley 62 is provided at the upper end of the bracket 61. During the process of transferring wire from one drawing machine to the next, to prevent the wire from bending or to ensure smooth transfer into the guide hole, the wire can first be transferred to the first fixed pulley 62. The first fixed pulley 62 acts as a transition, preventing bending.

[0041] The working principle of this utility model is as follows:

[0042] In this invention, firstly, a suitable wire drawing die 14 is installed into the die sleeve 22. Then, the steel wire to be drawn is passed through the second guide hole 17, the first guide hole 16, and the third guide hole 18 in sequence, and the end of the steel wire is fixed to the drum 2. Next, lubricating powder is filled into the first space 51, and the cover plate 9 is pressed onto the lubricating powder. At this time, rotating the pressure cap 13 drives the screw 12 to screw into the through hole 15. The lower end of the screw 12 then presses against the wire drawing die 14, preventing the wire drawing die 14 from slipping during the wire drawing process. After the screw 12 is pressed against the wire drawing die 14, the pressure cap 13 presses against the upper end of the pressure spring 10. The pressure spring 10 contracts under pressure and transmits the pressure to the upper end of the cover plate 9. The cover plate 9 then compresses the lubricating powder more firmly, ensuring better adhesion of the lubricating powder to the steel wire as it passes through the lubricating powder. At the same time, the compression spring 10 exerts a reaction force on the pressure cap 13, which can prevent the pressure cap 13 from causing the screw 12 to flip.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
