Description

Technical Field

[0001] This utility model relates to the technical field of spring steel wire processing equipment, and in particular to a spring steel wire cross-section shaping device. Background Technology

[0002] In the spring manufacturing industry, spring steel wire is a core raw material, and its quality directly affects the performance and lifespan of the finished spring. Traditional steel wire processing techniques have many drawbacks when dealing with the cross-sectional area of ​​the steel wire. On the one hand, the early processes such as drawing and rolling can easily lead to uneven diameters of the steel wire cross-section. This uneven force distribution can cause stress concentration during subsequent processing into springs, severely affecting product quality. On the other hand, traditional spring steel wire processing equipment typically requires multiple motors to drive different components, which not only increases the cost and complexity of the equipment but also presents challenges for synchronous control. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a spring steel wire cross-section shaping device to solve the problem of uneven spring steel wire cross-section in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A spring steel wire cross-section shaping device includes a worktable, a guide assembly, a traction assembly, and a shaping assembly sequentially arranged on the worktable. The traction assembly includes two symmetrically arranged mounting frames, a mounting plate arranged on the mounting frames, and an upper traction roller and a lower traction roller arranged on the mounting plate. The shaping assembly includes two symmetrically arranged upright frames, an upright plate arranged on the upright frames, and an upper shaping roller and a lower shaping roller arranged on the upright plate. A drive device is provided between the traction assembly and the shaping assembly to synchronously drive the upper traction roller, lower traction roller, upper shaping roller, and lower shaping roller to rotate synchronously.

[0006] To achieve the above technical solution, after the spring steel wire enters the device, it first passes through the guide assembly, which provides initial positioning and guidance for the wire, ensuring its precise entry into the traction assembly. The drive device then activates, causing the upper and lower traction rollers to rotate synchronously. Relying on the friction between the traction rollers and the wire, the wire is firmly clamped and pulled forward at a uniform speed, steadily conveying it to the shaping assembly. Simultaneously, the drive device synchronously drives the upper and lower shaping rollers. As the wire enters between the upper and lower shaping rollers, the specific contour shape of the roller surface applies uniform pressure to the wire's cross-section during its traction, gradually shaping it into a preset ideal form, ensuring stable performance of the wire in subsequent processing or use. This effectively solves the problem of localized breakage caused by large differences in wire diameter; through precise shaping operations, the diameter of the wire cross-section is made uniform throughout, and the internal stress distribution becomes more reasonable, greatly enhancing the overall structural strength of the wire.

[0007] In one embodiment of the present invention, the driving device includes a driving spur gear disposed at one end of the lower traction roller, a motor disposed at the other end of the lower traction roller, and a driven spur gear disposed at one end of the upper traction roller and meshing with the driving spur gear; one end of the upper shaping roller is provided with a driving spur gear, and one end of the lower shaping roller is provided with a driven spur gear meshing with the driving spur gear; a driving assembly is disposed between the upper traction roller and the upper shaping roller.

[0008] To achieve the above technical solution, after the motor is started, it drives the lower traction roller to rotate. Since one end of the lower traction roller is equipped with a driving spur gear, the driven spur gear at one end of the upper traction roller, which meshes with it, rotates synchronously. This causes the upper and lower traction rollers to operate in opposite directions and synchronously. The two rollers work closely together, relying on friction to stably clamp the spring steel wire and pull it forward at a set speed. When the upper traction roller is working, the drive assembly transmits power to the driving spur gear of the upper shaping roller, which in turn drives the lower shaping roller to rotate synchronously. This ensures that the upper and lower shaping rollers perform shaping treatment on the spring steel wire at the same speed, improving the consistency and accuracy of the shaping effect.

[0009] In one embodiment of the present invention, the drive assembly includes a first sprocket disposed on the upper traction roller and opposite to the driven spur gear, a second sprocket disposed on the upper shaping roller and opposite to the driving spur gear, and a chain meshing with the first sprocket and the second sprocket.

[0010] To achieve the above technical solution, a drive assembly consisting of sprockets and chains is used, which not only realizes efficient and accurate power transmission between the upper traction roller and the upper shaping roller, but also ensures the synchronization between the upper and lower traction rollers and the upper and lower shaping rollers.

[0011] In one embodiment of the present invention, the guide assembly includes a guide plate connecting the two mounting brackets, a plurality of guide holes formed on the guide plate, and a plurality of aperture adjustment components disposed on the guide plate and capable of adjusting the aperture of the guide holes.

[0012] To achieve the above technical solution, several aperture adjustment components are also provided on the guide plate to accommodate spring steel wires of different diameters. These components can adjust the aperture size of the guide holes as needed, ensuring that a suitable guiding effect is provided regardless of the diameter of the spring steel wire, thus avoiding offset or jamming caused by diameter mismatch.

[0013] In one embodiment of the present invention, the aperture adjustment assembly includes two sets of aperture adjustment components symmetrically arranged at the upper and lower ends of the guide hole.

[0014] To achieve the above technical solution, when processing spring steel wires of different diameters, the operator can adjust these two sets of aperture adjustment components to match the required aperture size. Since the aperture adjustment components are symmetrically distributed at the upper and lower ends of the guide hole, this helps maintain the symmetry and stability of the guide hole shape, reduces the impact of unbalanced forces caused by unilateral adjustment, and ensures the smoothness of the spring steel wire during the guiding process.

[0015] In one embodiment of the present invention, the aperture adjustment component includes an adjustment hole formed on the guide plate and communicating with the guide hole, a positioning block disposed in the adjustment hole, an adjustment bolt screwed on the positioning block, and an arc-shaped adjustment plate disposed inside the adjustment bolt.

[0016] To achieve the above technical solution, when it is necessary to adjust the diameter of the guide hole to accommodate spring steel wires of different diameters, the operator can move the arc-shaped adjustment plate by rotating the adjustment bolt. The two sets of hole diameter adjustment components work together to ensure the symmetry and consistency of the guide hole shape, so that the spring steel wire can pass smoothly and stably through the guide assembly into the subsequent processing stage.

[0017] In one embodiment of the present invention, the traction assembly is provided with two symmetrical first shock-absorbing assemblies, and the shaping assembly is provided with two symmetrical second shock-absorbing assemblies.

[0018] To achieve the above technical solution, the two symmetrical first damping components on the traction component are mainly used to absorb and buffer the vibrations that may be generated during the traction process; the two symmetrical second damping components on the shaping component are used to reduce the vibrations caused by pressure application during the shaping process.

[0019] In one embodiment of the present invention, the first shock-absorbing component includes a first shock-absorbing rod disposed on the upper end of the mounting plate and passing through the mounting frame, a handwheel disposed on the top end of the first shock-absorbing rod, and a first shock-absorbing spring sleeved on the first shock-absorbing rod and located between the mounting plate and the mounting frame.

[0020] To achieve the above technical solution, the first shock absorber effectively absorbs the vibration during the traction process through the first shock absorber spring, reducing the errors and instability caused by vibration.

[0021] In one embodiment of the present invention, the second shock-absorbing assembly includes a shock-absorbing plate located between the upright plate and the frame, a plurality of second shock-absorbing springs connected between the shock-absorbing plate and the upright plate, a second shock-absorbing rod disposed on the shock-absorbing plate and passing through the frame, and a rotating wheel disposed at the top of the second shock-absorbing rod.

[0022] The above technical solution, through the effective combination of damping plates and multiple second damping springs, can significantly reduce the vibration generated during the shaping process, protect the equipment from vibration damage, and extend its service life.

[0023] As described above, the spring steel wire cross-section shaping device of this utility model has the following beneficial effects: By precisely controlling the traction force and shaping pressure, the spring steel wire is subjected to uniform pressure throughout the entire processing, thereby ensuring the consistency of its diameter and the accuracy of its cross-sectional shape, effectively solving the problem of local breakage caused by large diameter differences. The aperture adjustment component and guide hole in the guide assembly, combined with the strong clamping and stable traction capability of the traction assembly, can efficiently straighten bent and uneven steel wires; the synchronous drive of the traction assembly and shaping assembly is achieved by a single motor and a precision gear transmission system, greatly simplifying the mechanical structure of the entire device.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please see Figures 1 to 5 This utility model provides a spring steel wire cross-section shaping device, including a worktable 1, a guide assembly, a traction assembly, and a shaping assembly sequentially arranged on the worktable 1. The traction assembly includes two symmetrically arranged mounting frames 2, a mounting plate 3 arranged on the mounting frames 2, and an upper traction roller and a lower traction roller arranged on the mounting plate 3. The shaping assembly includes two symmetrically arranged upright frames 6, an upright plate 7 arranged on the upright frames 6, and an upper shaping roller 8 and a lower shaping roller 9 arranged on the upright plate 7. A drive device is provided between the traction assembly and the shaping assembly to synchronously drive the upper traction roller, the lower traction roller, the upper shaping roller 8, and the lower shaping roller 9 to rotate synchronously.

[0033] As the spring steel wire enters the device while rotating, it first passes through the guide assembly, which provides initial positioning and guidance, ensuring its precise entry into the traction assembly. The drive unit then activates, causing the upper and lower traction rollers to rotate synchronously. Relying on the friction between the traction rollers and the steel wire, the wire is firmly clamped and pulled forward at a uniform speed, steadily conveying it to the shaping assembly. Simultaneously, the drive unit synchronously drives the upper shaping roller 8 and the lower shaping roller 9. As the steel wire enters between the upper and lower shaping rollers 9, the specific contour shape of the roller surfaces applies uniform pressure to the wire's cross-section during its traction, gradually shaping it into the preset ideal form, ensuring stable performance of the steel wire in subsequent processing or use. This effectively solves the problem of localized breakage caused by large differences in wire diameter; through precise shaping operations, the diameter of the steel wire cross-section is made uniform throughout, and the internal stress distribution becomes more reasonable, greatly enhancing the overall structural strength of the steel wire.

[0034] The driving device includes a driving spur gear 10 disposed at one end of the lower traction roller, a motor 11 disposed at the other end of the lower traction roller, and a driven spur gear 12 disposed at one end of the upper traction roller and meshing with the driving spur gear 10; a driving spur gear 13 is disposed at one end of the upper shaping roller 8, and a driven spur gear 14 meshing with the driving spur gear 13 is disposed at one end of the lower shaping roller 9; a driving assembly is disposed between the upper traction roller and the upper shaping roller 8.

[0035] After starting motor 11, motor 11 drives the lower traction roller to rotate. Since one end of the lower traction roller is equipped with a driving spur gear 10, the driven spur gear 12 at one end of the upper traction roller, which meshes with it, rotates synchronously. This causes the upper and lower traction rollers to operate in opposite directions and synchronously. The two work closely together, relying on friction to stably clamp the spring steel wire and pull the wire forward at a set speed. When the upper traction roller is working, the power is transmitted to the driving spur gear 13 of the upper shaping roller 8 through the drive assembly, which in turn drives the lower shaping roller 9 to rotate synchronously. This ensures that the upper and lower shaping rollers 9 shape the spring steel wire at the same speed, improving the consistency and accuracy of the shaping effect.

[0036] The drive assembly includes a first sprocket 15 disposed on the upper traction roller and opposite to the driven spur gear 12, a second sprocket 16 disposed on the upper shaping roller 8 and opposite to the driving spur gear 13, and a chain 17 meshing with the first sprocket 15 and the second sprocket 16. The drive assembly consisting of the sprockets and chain 17 not only achieves efficient and accurate power transmission between the upper traction roller and the upper shaping roller 8, but also ensures the synchronization between the upper and lower traction rollers and the upper and lower shaping rollers 9.

[0037] The guiding assembly includes a guide plate 18 connecting the two mounting brackets 2, a plurality of guide holes 19 formed on the guide plate 18, and a plurality of aperture adjustment components disposed on the guide plate 18 and capable of adjusting the aperture of the guide holes 19. To accommodate spring steel wires of different diameters, the guide plate 18 is also provided with a plurality of aperture adjustment components. These components can adjust the aperture size of the guide holes 19 as needed, ensuring that a suitable guiding effect is provided regardless of changes in the diameter of the spring steel wire, avoiding offset or jamming caused by diameter mismatch.

[0038] The aperture adjustment assembly includes two sets of aperture adjustment components symmetrically arranged at the upper and lower ends of the guide hole 19. When processing spring steel wires of different diameters, the operator can adjust these two sets of aperture adjustment components to adapt to the required aperture size. Because the aperture adjustment components are symmetrically distributed at the upper and lower ends of the guide hole 19, this helps maintain the symmetry and stability of the guide hole 19's shape, reduces the impact of unbalanced forces caused by unilateral adjustment, and ensures the smoothness of the spring steel wire during the guiding process.

[0039] The aperture adjustment component includes an adjustment hole formed on the guide plate 18 and communicating with the guide hole 19, a positioning block 20 disposed in the adjustment hole, an adjustment bolt 21 screwed onto the positioning block 20, and an arc-shaped adjustment plate 22 disposed inside the adjustment bolt 21. When it is necessary to adjust the aperture of the guide hole 19 to accommodate spring steel wires of different diameters, the operator can move the arc-shaped adjustment plate 22 by rotating the adjustment bolt 21. The two sets of aperture adjustment components work together to ensure the symmetry and consistency of the shape of the guide hole 19, so that the spring steel wire can pass smoothly and stably through the guide assembly into the subsequent processing stage.

[0040] The traction assembly has two symmetrical first damping components, and the shaping assembly has two symmetrical second damping components. The two symmetrical first damping components on the traction assembly are mainly used to absorb and buffer vibrations that may be generated during traction; the two symmetrical second damping components on the shaping assembly are used to reduce vibrations caused by pressure application during the shaping process.

[0041] The first shock absorption assembly includes a first shock absorber rod 23 disposed on the upper end of the mounting plate 3 and passing through the mounting frame 2, a handwheel 24 disposed at the top end of the first shock absorber rod 23, and a first shock absorber spring 25 sleeved on the first shock absorber rod 23 and located between the mounting plate 3 and the mounting frame 2. The first shock absorption assembly effectively absorbs vibrations during traction through the first shock absorber spring 25, reducing errors and instability caused by vibrations.

[0042] The second vibration damping assembly includes a damping plate 26 located between the upright plate 7 and the support frame 6, a plurality of second damping springs 27 connected between the damping plate 26 and the upright plate 7, a second damping rod 28 disposed on the damping plate 26 and passing through the support frame 6, and a rotating wheel 29 disposed at the top of the second damping rod 28. Through the effective combination of the damping plate 26 and the plurality of second damping springs 27, the vibration generated during the shaping process can be significantly reduced, protecting the equipment from vibration damage and extending its service life.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
