Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, specifically to a dry wire drawing machine wire pressing device. Background Technology

[0002] The wire drawing machine is a non-slip dry continuous wire drawing machine that can accumulate wire. During the drawing process, there is no relative sliding between the steel wire and the surface of the drum along the circumference of the drum. The wear on both surfaces is relatively small. Furthermore, when one of the drums in the middle is temporarily stopped, the drums behind it can still work normally for a period of time based on their respective accumulation of wire. This type of machine has the advantages of simple structure, convenient operation and maintenance, and low manufacturing cost.

[0003] According to publicly available patent CN216606680U, an adjustable wire drawing machine pressing device belongs to the field of wire drawing machine technology. This adjustable wire drawing machine pressing device includes a base, a support plate fixedly connected to the upper end of the base, a rotating rod passing through the upper end of the support plate, a turntable fixedly connected to the left end of the rotating rod, a limiting plate fixedly connected to the outside of the rotating rod, the limiting plate being located on the left side of the support plate, a torsion spring sleeved on the outside of the rotating rod, the torsion spring being located on the right side of the support plate, a bracket fixedly connected to the right end of the rotating rod, the left end of the bracket being fixedly connected to the left end of the torsion spring, a roller rotatably connected to the right end of the bracket, and a first limiting piece fixedly connected to the left end of the support plate. In the process of realizing this utility model, the inventor discovered prior art... At least the following problems remain unresolved: The rotating rod can be fixed by the interaction of the first and second limiting plates, and under the axial force of the torsion spring, preventing rebound. When pressure needs to be applied to steel wires of different thicknesses, pressing the bracket along the axial direction of the rotating rod separates the first and second limiting plates, releasing the limiting. Under the radial force of the torsion spring, the bracket rebounds, separating the roller from the steel wire. Repeating the pressing steps allows for the re-application of pressure to steel wires of different thicknesses. However, the traditional method of adjusting steel wire pressure has low precision, affecting the quality of wire pressing. Furthermore, the torsion spring is inconvenient to disassemble and replace, and as a consumable component, it is prone to damage after prolonged use. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Example 1: A dry wire drawing machine wire pressing device, see [link to example]. Figures 1 to 4 The device includes: a base 1, on which a support seat 12 is fixedly connected to the center of its surface; a wire pressing mechanism, mounted on the support seat 12, for pressing steel wire; and a pressure adjusting component, located at one end of the wire pressing mechanism, for precisely adjusting the pressure applied to the steel wire by the wire pressing mechanism. The pressure adjusting component includes: a worm gear 42, fixedly connected to one end of the wire pressing mechanism; and a U-shaped first connecting seat 4, fixedly connected to the end of the support seat 12 near the worm gear 42. The inner cavity of the first connecting seat 4 is rotatably connected to a worm 41 via a sealed bearing, and the worm 41 meshes with the worm gear 42. The lead angle of the worm 41 is less than or equal to the equivalent friction angle of the worm 41 pair material.

[0035] This device, through its pressure regulating component, achieves the following during use:

[0036] Precise pressure control: The reduction transmission characteristics of the worm gear 42 and worm 41 can convert the adjustment action into a small pressure change of the wire pressing mechanism on the steel wire, avoiding the force fluctuation of the traditional torsion spring 23 adjustment, ensuring that steel wires of different thicknesses can obtain the appropriate pressure, and solving the problem of unstable wire pressing quality.

[0037] Self-locking: Because the lead angle of worm 41 is less than or equal to the equivalent friction angle of the worm 41 pair material, the meshing of worm 41 and worm wheel 42 has a reverse self-locking function. After adjustment, the pressure can remain stable for a long time (without rebound), avoiding pressure deviation caused by vibration in traditional structures. It is especially suitable for continuous and precise control of wire pressure during high-speed wire drawing.

[0038] Easy to operate: Pressure can be adjusted by rotating the worm gear 41 without complicated tools. It is more intuitive than the traditional axial pressing and unlocking adjustment method, reduces pressure deviation caused by operation error, and reduces the difficulty of manual adjustment.

[0039] For details, see Figure 1 and Figure 2The wire pressing mechanism includes: a connecting column 2, rotatably connected to a support base 12 via a sealed bearing, one end of the connecting column 2 near the support base 12 penetrating the support base 12 and fixedly connected to the center of the worm gear 42; a connecting disc 26, connected to one end of the connecting column 2 via a disassembly assembly, a connecting rod 27 fixedly connected to one side of the connecting disc 26, and a U-shaped second connecting seat 28 fixedly connected to the other end of the connecting rod 27, a torsion spring 23 sleeved on the outer side of the connecting column 2, the torsion spring 23 being limited between the connecting disc 26 and the support base 12 by a limiting assembly; and a pressure roller 21, with a rotating shaft 29 penetrating the middle of the pressure roller 21, the rotating shaft 29 being rotatably mounted on the second connecting seat 28 via a sealed bearing, the limiting assembly constraining the torsion spring 23 between the connecting disc 26 and the support base 12, and the preload of the torsion spring 23 ensuring that the pressure roller 21 applies uniform and continuous pressure to the steel wire.

[0040] Further, see Figure 2 and Figure 3The disassembly and assembly components include: a rectangular groove 5, located at one end of the connecting plate 26 near the connecting post 2; a rectangular block 51, fixedly connected to the end of the connecting post 2 near the rectangular groove 5, the position of the rectangular block 51 corresponding to the position of the rectangular groove 5 and the size being adapted; and a fixing bolt 52, located at the end of the connecting plate 26 away from the rectangular groove 5, the fixing bolt 52 rotating through the connecting plate 26 and threadedly connected to the threaded hole on the rectangular groove 5 and the rectangular block 51. The limiting components include a first limiting plate 24 and a second limiting plate 25, the first limiting plate 24 and the second limiting plate 25 respectively fixedly connected to the opposite ends of the support base 12 and the connecting plate 26. The two ends of the torsion spring 23 are respectively placed below the first limiting plate 24 and the second limiting plate 25. Through the precise engagement of the rectangular block 51 and the rectangular groove 5, the relative angle between the connecting post 2 and the connecting plate 26 can be automatically aligned when disassembling and assembling the connecting plate 26, ensuring that the two ends of the torsion spring 23 can accurately engage below the first limiting plate 24 and the second limiting plate 25, avoiding the problems caused by traditional disassembly and assembly. The spring installation misalignment caused by angular deviation ensures that the pressure adjustment accuracy is not affected by maintenance operations. The fixing bolt 52, which passes through the threaded locking mechanism of the connecting plate 26 and the rectangular block 51, allows for easy disassembly and fixing of the connecting plate 26 with only simple tools. During disassembly, loosening the fixing bolt 52 separates the connecting plate 26, allowing direct removal of the torsion spring 23. During installation, the rectangular positioning allows for quick resetting, and tightening the fixing bolt 52 completes the fixing, making disassembly and assembly convenient. The first limiting plate 24 and the second limiting plate 25 support both ends of the torsion spring 23, forming axial constraint (preventing axial movement of the spring under force) and radial limitation (avoiding spring twisting and deformation), ensuring that the preload of the torsion spring 23 is stably transmitted to the pressure roller 21. Combined with the deviation-free installation of the rectangular positioning, the space below the first limiting plate 24 and the second limiting plate 25 provides an independent removal channel for the torsion spring 23. After disassembling the connecting plate 26, the spring can be directly pulled out between the two limiting plates without disassembling other components, improving the efficiency of torsion spring 23 replacement.

[0041] It is worth noting that, see Figure 1 A protective cover 3 is provided on the outer side of the first connecting seat 4. The protective cover 3 is sleeved on the outer side of the pressure regulating component. A bolt 31 passes through one end of the outer side of the protective cover 3, and the bolt 31 is threaded to the surface of the first connecting seat 4. The protective cover 3 isolates external dust and metal debris (generated during the wire drawing process) from entering the meshing point of the worm gear 42 and worm 41, avoiding adjustment jamming or wear caused by impurities, and ensuring that the pressure regulating component maintains accurate transmission for a long time. The protective cover 3 also covers the pressure regulating component to prevent the operator from accidentally touching the rotating worm 41, and at the same time prevents the lubricating oil used for lubrication of the worm gear 42 and worm 41 from leaking out and contaminating the working environment. The protective cover 3 is detachably connected by the bolt 31, which is convenient for disassembly and assembly, and maintenance of the worm 41 and worm gear 42.

[0042] It is worth noting that, see Figure 4 The second connecting seat 28 is equipped with a bearing mounting seat 210 at the end away from the connecting rod 27. The sealed bearings at both ends of the rotating shaft 29 are connected in the bearing mounting seat 210. The bearing mounting seat 210 provides high-precision rotational support for the rotating shaft 29, reduces the frictional resistance when the pressure roller 21 rotates, and ensures that the pressure roller 21 rotates synchronously and smoothly with the steel wire when it passes through. This avoids the rotational obstruction caused by wear in the direct hinge structure, prevents the steel wire surface from being scratched or the pressure force from fluctuating, and the rigid support of the bearing can eliminate the radial wobble of the rotating shaft 29, so that the pressure of the pressure roller 21 on the steel wire is always perpendicular to the contact surface. This avoids the problem of uneven pressure caused by the tilt of the pressure roller 21 in the traditional loose structure, ensures that the steel wire surface is subjected to consistent force, and improves the quality of the pressure.

[0043] It is worth mentioning that, see Figure 1 The base 1 has mounting holes 11 at each of its four corners, and the mounting holes 11 correspond to the preset mounting positions on the wire drawing machine. The mounting holes 11 at the four corners of the base 1 are fully adapted to the preset positions on the wire drawing machine, which can be quickly aligned and fixed to ensure that the wire pressing mechanism and the wire drawing path remain coaxial, thus avoiding the wire force deviation caused by traditional misalignment installation.

[0044] It is worth mentioning that, see Figure 1 The pressure roller 21 has a groove 22 in the middle of its outer periphery. The groove 22 is semi-circular. The semi-circular groove 22 fits the outer contour of the steel wire, increasing the contact area between the pressure roller 21 and the steel wire, forming a circumferential wrapping constraint, and preventing the steel wire from detaching from the pressure roller 21 during high-speed wire drawing, which would affect the wire pressing effect.

[0045] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
