Description

Technical Field

[0001] This utility model relates to the field of steel wire production and processing technology, specifically to a steel wire drawing device. Background Technology

[0002] Mechanical analysis based on the entire load-failure process of steel mesh shows that appropriate drawing treatment is beneficial to improving the mechanical properties of steel mesh. During the production process of steel wire mesh, the grains are refined through the drawing process, causing work hardening of the steel. The internal crystal structure of the steel will deform and generate defects such as dislocations. These defects can hinder the slip of the crystal structure, thereby improving the strength and toughness of the steel wire. This allows the steel mesh to better withstand the various loads on high-speed rail and light rail, improving the safety and stability of the structure to meet the requirements of high-speed rail and light rail.

[0003] Before drawing steel wire, lubricating powder needs to be applied to the surface of the steel wire. After passing through the drawing die, the temperature of the steel wire rises, and the attached lubricating powder is prone to burning and clumping. The utility model patent with announcement number CN219357422U provides a steel wire drawing device with lubrication and cooling effect. It improves the above technical problems by sequentially setting a borax bath and an annular air knife. However, this structure also brings serious dust problems. Utility Model Content

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] Example

[0027] Please see Figures 1-4 This utility model provides a steel wire drawing device, including a machine base 1, on which a lubricating powder box 2, a drawing die 3, and a traction disc 4 are sequentially arranged. The drawing die 3 is a cylindrical body equipped with a cooling coil 5 on its outer periphery, and has a through drawing channel 6 inside. The cooling coil 5 is connected to a heat exchanger 7 and a water pump 8, and the cooling coil is connected to a cold water source to achieve temperature control of the drawing die during the drawing process.

[0028] The lubricating powder box 2 contains lubricating powder. After the steel wire passes through the lubricating powder box 2, the surface of the steel wire is covered with lubricating powder. Upstream of the steel wire, the drawing device is equipped with multiple staggered guide wheels 9. These guide wheels 9 have guide grooves 10 circumferentially to help stabilize the conveying direction of the steel wire. The guide wheels 9 adopt a split structure. The rims 11 on both sides are connected by sleeves 13 and connecting rods 12, and are maintained with a certain tension by axial grooves 14, sliders 15 and spring system, ensuring that the guide wheels 9 have a certain degree of adaptability to match the drawing of steel wires of different specifications.

[0029] The drawing channel 6 is designed as three continuous sections: inlet section 17, deformation section 18, and sizing section 19, wherein the deformation section 18 is a conical surface connecting the inlet section 17 and the sizing section 19. The deformation section 18 and the sizing section 19 are integrally formed, while the deformation section 18 and the inlet section 17 can be detachably connected through the slot 20 and the insert 21.

[0030] To enable rapid replacement of the deformation section 18 and the sizing section 19, a groove 22 is provided on the machine base 1, with a hinged limiting block 23 embedded therein. The limiting block 23 abuts against the sizing section 19 and is electrically connected to the industrial control board via a servo electric push rod 24 for precise control. In addition, a pressure sensor 25 is embedded in the limiting block 23 to monitor pressure changes during the drawing process and feed the data back to the industrial control board. The industrial control board then adjusts the locking force of the servo electric push rod 24 on the drawing die 2.

[0031] Machine 1 is also equipped with a gas collection hood 26, which is connected to a negative pressure fan 28 via a suction pipe 27 to collect and process the gas and steel chips generated during the drawing process. The suction pipe 27 is connected to a steel chip separation pipe 29 via a flange. The latter has a receiving cylinder 30 with magnets 31 evenly distributed around its outer periphery for adsorbing and separating metal chips. A pressure sensor is also installed between the negative pressure fan 28 and the steel chip separation pipe 29 to monitor the air pressure in the duct and determine the blockage status. The sensor then relays the information to the industrial control board. If a blockage is detected, the magnets are pulled out of the receiving cavity 30 after the flange is removed, and the magnets fall out of the steel chip separation pipe by their own weight, ensuring the efficient operation and safe monitoring of the entire system.

[0032] The working principle of this invention is as follows: the steel wire first passes through the lubricating powder box 2 containing lubricating powder via the guide wheel 9, and after the lubricating powder adheres to its surface, it enters the drawing die 3. The cooling coil 5 controls the temperature of the drawing die through circulating cold water. In the deformation section 18, the steel wire is subjected to the compressive force of the conical surface, undergoing plastic deformation and reducing its diameter. Subsequently, the steel wire enters the sizing section 19, where the diameter of the steel wire is maintained for a period of time, stabilizing to the required size. The deformation section 18 and the sizing section 19 can be detachably connected via slots 20 and inserts 21, facilitating quick replacement of worn or damaged dies and meeting different drawing requirements. A pressure sensor 25 is embedded in the limit block 23 to monitor pressure changes during the drawing process and feeds the data back to the industrial control board. The industrial control board adjusts the locking force of the servo electric push rod 24 on the drawing die based on the pressure data, ensuring the stability of the drawing process.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
