Description

Technical Field

[0001] This invention relates to the field of wire spinning machine technology, and more specifically to a rolling guide device applied to a high-speed wire spinning machine. Background Technology

[0002] In the production process of high-speed wire rod, the wire spinning machine is a key piece of equipment that transforms the high-speed moving wire from a straight state to a spiral coil shape and distributes it evenly on the Steyrmo cooling line. As an important component of the wire spinning machine, the guide device's technical performance directly affects the wire spinning quality and production efficiency. Its key role is to adjust the movement trajectory of the wire during the spinning process and stabilize the subsequent coiling process.

[0003] The guide structure is relatively simple. The key is to use materials with high wear resistance and high smoothness to avoid scratching the wire. However, the installation and alignment of the guide are quite strict. If the inlet guide is not aligned with the clamping groove or the gap between the outlet guide and the clamping roller is not proper, it will lead to unstable wire running and increase the risk of steel piling. Installation deviation may also cause the wire to shift at the inlet of the wire tube, affecting the coil quality. Furthermore, as a high-speed rotating device, the spinning machine's vibration exacerbates the impact load on the guide components, leading to bearing damage, bolt breakage, and other issues, indirectly affecting the guide's stability. Long-term vibration can also deform the spinning disc, further deteriorating the coil quality. This invention proposes a solution to this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a rolling guide device for use in high-speed wire spinning machines. In order to meet the high-speed transmission requirements of high-speed spinning machines, while meeting the material requirements, the installation requirements also affect the operational stability, especially the vibration problem caused by impact loads during continuous operation, which aggravates structural damage.

[0005] The objective of this invention can be achieved through the following technical solution: a rolling guide device applied to a high-speed wire drawing machine, comprising an upper jumper plate, a lower jumper plate, and a mounting plate, wherein the upper jumper plate and the lower jumper plate are arranged from top to bottom, and the mounting plate is symmetrically arranged along the positions of the upper jumper plate and the lower jumper plate, and the upper jumper plate and the lower jumper plate cooperate with the mounting plate to form a guide groove; The upper jump plate is provided with an axial corrugated strip corresponding to the wire transmission direction on the inner wall of the guide groove, and the two mounting plates are provided with lateral corrugated strips on the inner wall of the guide groove. The axial corrugated strips are used to perform amplitude jump action on the wire, and the lateral corrugated strips are used to perform vibration reduction treatment on the wire.

[0006] The guide groove is further configured such that one end of the guide groove is flared and the cross-section of the guide groove is an upwardly curved arch shape.

[0007] The two mounting plates are further configured such that they are fixed together by fastening screws, and the upper and lower mounting plates are provided with fixing holes for the corresponding fastening screws at one end near the guide groove, and the other end of the upper and lower mounting plates is provided with slots for matching fastening screws.

[0008] The configuration is further defined as follows: the two ends of the axial corrugated strip are hinged to the upper jump plate, and the axial corrugated strip is provided with alternating action protrusions and passive recesses along its outline. An action cylinder is installed on the upper jump plate at the external position corresponding to the action protrusion.

[0009] The further configuration is as follows: the output shaft of the actuating cylinder passes through the upper jump plate and is fixedly connected to the actuating protrusion, and the direction of the output shaft of the actuating cylinder is parallel to the normal direction at the actuating protrusion.

[0010] The further configuration is as follows: the actuating protrusion is curved upward relative to the passive recess in a direction deviating from the guide groove, the passive recess is curved downward in a direction close to the guide groove, and the passive recess is tangent to the lower surface of the upper springboard.

[0011] The lateral corrugated strip is further configured such that both ends are fixedly connected to the mounting plate, and pressure-receiving protrusions and pressure-receiving recesses are sequentially distributed on the lateral corrugated strip. The pressure-receiving protrusions are in the shape of an outwardly curved arch along the direction close to the guide groove, and the pressure-receiving recesses are in the shape of an inwardly curved arch along the direction away from the guide groove.

[0012] The configuration is further defined as follows: the pressure-reducing protrusions and pressure-receiving concave portions in the two lateral corrugated strips are arranged in an alternating manner, and a top post is rotatably mounted on the mounting plate at the position of the pressure-reducing protrusion along the width direction of the lateral corrugated strip, with the outer surface of the top post remaining tangent to the inner wall of the lateral corrugated strip.

[0013] The configuration is further defined as follows: a swing sleeve is rotatably mounted at the center point of the top column, and a corresponding coiled spring is provided inside the top column. The swing sleeve has an elliptical cross-section, and the swing sleeve rotates non-directionally relative to the top column through the coiled spring.

[0014] The present invention has the following beneficial effects: Addressing the three core problems of traditional guides—difficult installation and alignment, high-speed friction, and frequent vibration damage—this design achieves breakthroughs in "convenient installation, low-friction transmission, and stable vibration operation" through the coordinated design of a trumpet-shaped guide groove, a slot adjustment structure, axial corrugated strips, and lateral vibration absorption components. This also reduces the operational difficulty of later replacement and maintenance with the simplest structure.

[0015] Traditional guide devices cannot fine-tune the position of the jump plate. If the height deviation of the guide groove is large during installation, it is easy to cause the wire to jam and accumulate (i.e., "steel pile-up"). The jump groove design of this invention can realize the height adjustment process within a positive and negative range, avoid the risk of steel pile-up to the greatest extent, and reduce downtime losses. The axial corrugated strip reduces the contact time between the wire and the inner wall through periodic jump distance, and the contact is a flexible push (rather than rigid friction), which reduces the degree of scratches on the wire surface.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: To meet the high-speed transmission requirements of high-speed spinning machines, while satisfying material requirements, installation requirements also affect operational stability, especially the vibration problems caused by impact loads during continuous operation, which exacerbate structural damage. The following technical solution is proposed to address this: Reference Figures 1-7 A rolling guide device for high-speed wire spinning machine includes an upper jump plate 1, a lower jump plate 2 and a mounting plate 3. The upper jump plate 1 and the lower jump plate 2 are arranged from top to bottom. The mounting plate 3 is symmetrically arranged along the positions of the upper jump plate 1 and the lower jump plate 2. The upper jump plate 1 and the lower jump plate 2 cooperate with the mounting plate 3 to form a guide groove 7. The upper plate 1 is provided with an axial corrugated strip 6 corresponding to the direction of wire transmission on the inner wall of the guide groove 7. The two mounting plates 3 are provided with lateral corrugated strips 8 corresponding to the inner wall of the guide groove 7. The axial corrugated strip 6 performs amplitude jump action on the wire, and the lateral corrugated strip 8 performs vibration reduction treatment on the wire. One end of the guide groove 7 is opened in a trumpet shape, and the cross-section of the guide groove 7 is an upward curved arch shape.

[0021] Basic Principle Explanation: The technical structure proposed in this invention is briefly described in contrast to conventional guide structures: The wire enters through the flared inlet of the guide groove 7. This flared structure guides the high-speed moving wire precisely into the guide channel, preventing inlet deviation. The guide groove 7 has an upwardly curved arched cross-section, adapting to the wire's trajectory and reducing frictional resistance during transmission. During transmission, the axial corrugated strips 6 on the inner wall of the upper jump plate 1 apply axial amplitude jump action to the wire, while the lateral corrugated strips 8 on the inner walls of the two mounting plates 3 provide lateral vibration reduction for the wire, jointly ensuring the stability of the wire during high-speed transmission. The design of the horn-shaped inlet and the guide groove with the arched cross-section reduces the stringent requirements for installation alignment accuracy, reduces wire misalignment caused by alignment deviation, improves the quality of the coil, and the overall structure is very simple, reducing the difficulty of replacement or disassembly. The key is that high wear-resistant materials are added to the contact areas of the axial corrugated strip 6, the lateral corrugated strip 8, and the lower jump plate 2. The overall structure is adapted to the needs of high-speed wire transmission, and while meeting the requirements of high wear resistance and high smoothness materials, it makes up for the potential instability caused by installation deviation.

[0022] Example 2: Explanation of the operation process of the upper and lower ramps: The two mounting plates 3 are fixed together by fastening screws. The upper plate 1 and the lower plate 2 have fixing holes for the corresponding fastening screws at one end near the guide groove 7, and the other end of the upper plate 1 and the lower plate 2 have slots 5 for matching fastening screws. The two ends of the axial wave strip 6 are hinged to the upper plate 1, and the axial wave strip 6 has actuating protrusions 601 and passive recesses 602 intersecting along its outline. The upper plate 1 is mounted on the outer position of the actuating protrusion 601. The output shaft of the actuating cylinder 4 passes through the upper plate 1 and is fixedly connected to the actuating protrusion 601. The direction of the output shaft of the actuating cylinder 4 is parallel to the normal direction of the actuating protrusion 601. The actuating protrusion 601 is curved upward relative to the passive recess 602 in a direction away from the guide groove 7. The passive recess 602 is curved downward in a direction close to the guide groove 7, and the passive recess 602 is tangent to the lower surface of the upper plate 1.

[0023] Solution Description: The wire is conveyed at high speed from the production line to the spinning machine. It first contacts the trumpet-shaped inlet of guide groove 7. This trumpet-shaped inlet features a gradually expanding angle design, providing a dual "guiding-correcting" function for the wire. Even with slight transmission deviations, the smooth surface of the inner wall of the trumpet-shaped inlet gradually corrects the wire to the central axis of the guide groove, preventing direct impact with the sidewalls and potential scratches or deviations. After entering guide groove 7, the wire moves along the arched cross-section. The radius of curvature of the guide groove's cross-section matches the wire diameter, ensuring "point contact" rather than "surface contact" between the wire and the inner wall of the guide groove. "Contact" significantly reduces frictional resistance. At the same time, the axial corrugated strip 6 of the upper plate 1 and the lateral corrugated strip 8 of the two mounting plates 3 start to work simultaneously: the axial corrugated strip drives the wire to float slightly up and down along the transmission direction through periodic amplitude jumps; the lateral corrugated strip absorbs the lateral vibration of the wire through its own deformation. The two form a synergistic mechanism of "axial guidance + lateral vibration stabilization" to ensure that the wire is always transmitted stably along the preset trajectory. The arched guide groove and amplitude jump design of this device not only reduce frictional resistance, but also avoid the wire from contacting the inner wall for a long time through periodic floating, reducing the temperature rise of the guide components. The upper ramp 1 and lower ramp 2 serve as the upper and lower sidewalls of the guide groove 7. Their position adjustment and the movement control of the axial corrugated strip directly determine the stability of the axial transmission of the wire. The specific operating details are as follows: First, fasten the upper and lower jump plates 1 and 2 by passing the screws through the fixing holes near the entrance of the guide groove, and initially fix them to the mounting plate 3. Then, adjust the position of the jump groove 5 at the other end of the upper / lower jump plates according to the diameter of the wire. The jump groove 5 adopts a long strip hole design (the width matches the fastening screw). After loosening the screw, the jump plate can be moved up and down to make the height of the guide groove 7 match the diameter of the wire. After the adjustment is completed, tighten the screw again to ensure that the guide groove does not have the problem of "too loose and wobbling" or "too tight and stuck". After the equipment is started, the actuating cylinder 4 (using a small pneumatic cylinder) drives the output shaft to periodically extend and retract according to the preset parameters of the wire specifications. Since the output shaft is fixedly connected to the actuating protrusion 601 of the axial wave strip 6, and the direction of the output shaft is parallel to the normal of the actuating protrusion, the extension and retraction of the output shaft will cause the actuating protrusion to swing up and down around the hinge points at both ends: when the output shaft extends, the actuating protrusion lifts up (offset from the guide groove 7), and at this time the wire slides along the surface of the passive recess 602 under its own inertia (the passive recess is tangent to the lower surface of the upper jump plate 1 to ensure smooth sliding); when the output shaft retracts, the actuating protrusion presses down (close to the guide groove 7), pushing the wire forward with a small "jump distance", forming a periodic action of "lifting-sliding-pressing-jump distance".

[0024] Example 3: Supplementary explanation of the lateral corrugated strip in conjunction with the technical content of Example 2; The two ends of the lateral corrugated strip 8 are fixedly connected to the mounting plate 3. The lateral corrugated strip 8 is provided with pressure-changing protrusions 801 and pressure-receiving recesses 802 in sequence. The pressure-changing protrusions 801 are outwardly curved arches along the direction close to the guide groove 7, and the pressure-receiving recesses 802 are inwardly curved arches along the direction away from the guide groove 7. The pressure-changing protrusions 801 and pressure-receiving recesses 802 in the two lateral corrugated strips 8 are arranged alternately. The mounting plate 3 is rotatably mounted with a top post 10 at the position of the pressure-changing protrusions 801 along the width direction of the lateral corrugated strip 8. The outer surface of the top post 10 is tangent to the inner wall of the lateral corrugated strip 8. The center point of the top post 10 is rotatably mounted with a swing sleeve 9. The top post 10 is provided with a corresponding coil spring 11 inside the swing sleeve 9. The cross-section of the swing sleeve 9 is elliptical, and the swing sleeve 9 rotates non-directionally relative to the top post 10 through the coil spring 11.

[0025] Solution Description: When the wire vibrates laterally, the pressure-transforming protrusion 801 or the pressure-receiving concave portion 802 of the lateral corrugated strip 8 is acted upon first. The pressure-transforming protrusion 801 bends outward and can withstand the lateral pressure of the wire through its own elastic deformation, converting the vibration energy into deformation potential energy. The pressure-receiving concave portion 802 bends inward and can deform when subjected to the tension of the wire, thus absorbing energy. At the same time, the lateral corrugated strips of the mounting plates 3 on both sides are arranged in an alternating pattern of "pressure-transforming protrusion - pressure-receiving concave portion" (i.e., the left pressure-transforming protrusion corresponds to the right pressure-receiving concave portion), so that the lateral vibration energy of the wire is alternately absorbed by the corrugated strips on both sides, avoiding damage to the corrugated strips caused by excessive force on one side. The top column 10 is rotatably mounted on the mounting plate 3 via bearings. Its outer surface is tangent to the inner wall of the lateral corrugated strip 8, providing stable support for the corrugated strip (preventing excessive deformation) and rotating synchronously with the slight movements of the corrugated strip, reducing frictional resistance at the support. The swing sleeve 9 inside the top column 10 is elliptical and connected to the inner wall of the top column via a coiled spring 11. When the lateral corrugated strip transmits vibration to the top column, the swing sleeve 9 will rotate around the center in an unpredictable manner due to the centrifugal force generated by the vibration: if the vibration direction is to the left, the long axis of the swing sleeve will rotate to the right to counteract the force; if the vibration direction is to the right, the long axis of the swing sleeve will rotate to the left. Through this adaptive rotation, the concentrated vibration energy is distributed to all directions of the top column, avoiding local stress concentration. Long-term operational stability assurance process: During continuous operation, the coil spring 11 can ensure that the swing sleeve 9 always maintains a flexible rotation state through its own elastic restoring force, avoiding jamming caused by long-term vibration; at the same time, both the top column and the swing sleeve are treated with wear-resistant coatings (such as titanium nitride coatings) to reduce wear caused by rotational friction and ensure long-term stable operation of the components.

[0026] In summary, this system aims to solve the problems of difficult alignment, high friction during high-speed transmission, and severe vibration damage associated with traditional guide rail installations. It includes an upper plate, a lower plate, and symmetrically arranged mounting plates. These three components work together to form a guide groove with a trumpet-shaped end and an arched cross-section. The upper plate has axial corrugated strips on its inner wall, which, driven by an actuating cylinder, alternately swing between the actuating protrusions and the passive concave parts, achieving axial amplitude jumps in the wire and reducing friction and scratches. The mounting plates have lateral corrugated strips on their inner wall, with alternating distribution of pressure-transforming protrusions and pressure-receiving concave parts to absorb lateral vibrations. These, combined with the elliptical swing sleeve within the top column, further disperse vibration energy. Adaptable to different wire specifications and high-speed transmission conditions, this system significantly reduces component wear and vibration damage, improves wire feeding quality and production efficiency, and extends equipment lifespan.
