Description

Technical Field

[0001] This invention belongs to the field of steel wire processing technology, specifically relating to a steel wire tipping machine capable of adjusting the tip diameter and tip angle. Background Technology

[0002] A tipping mill is an auxiliary device for drawing copper, aluminum, steel, and iron wire. It mainly consists of rollers, speed reduction transmission, etc. It is used for tipping operations before drawing various metal wires. That is, the ends of the raw materials need to be tipped smaller by the tipping mill before passing through the drawing die holes for drawing processing.

[0003] The existing tipping mill works by rotating two rollers and inserting a steel wire vertically between them. The wire is then tipped by the pressure exerted by the rollers. However, existing tipping mills can only handle a limited range of wire diameters. When tipping wires with significantly different diameters, different types of rollers need to be replaced, which is time-consuming, labor-intensive, and affects subsequent work efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a wire tipping machine capable of adjusting the tip diameter and tip angle. Using this invention, the tip diameter and tip angle can be adjusted without changing different types of rolls, meeting the different tipping requirements of wires with varying diameters. It avoids the cumbersome roll replacement process and has the advantages of wide applicability, strong versatility, high tipping efficiency, high tipping quality, ease of use, and time and labor saving.

[0005] The objective of this invention can be achieved through the following technical measures:

[0006] This invention discloses a wire tipping machine capable of adjusting the tip diameter and tip angle, comprising a feeding device and a tipping device arranged collinearly along the wire's forward movement direction (the feeding device horizontally conveys the wire tip forward to the tipping station in the tipping device; upon reaching the tipping station, the wire tip surface is clamped by a roller assembly, and a transmission component drives a rotating drum to rotate, which in turn drives the roller assembly to rotate around the wire to tip it). A base is supported below the tipping device by a fixing buckle, a semi-circular support, and a fixing clamp (the base supports the tipping device; the fixing buckle...). The semi-circular support and fixed clamp, in addition to supporting the tipping device, also limit the left-right and up-down translational degrees of freedom of the tipping device and prevent the tipping device from moving forward and backward or swaying left and right. A transmission assembly consisting of a drive unit, a fourth gear, and a gear connected in sequence can drive the tipping device to rotate (the drive unit drives the fourth gear to rotate, the fourth gear meshes with the gear to drive the rotating drum to rotate, and the rotating drum in turn drives the rolling mill components to rotate around the steel wire to tip it). The tipping device includes a rotating drum with a gear ring around its front end on its outer surface (the gear meshes with the fourth gear). The meshing of the wheels drives the drum to rotate. A sliding disc is fitted inside the rear half of the drum. Within the drum's inner cavity, at least three sets of rollers with axes parallel to the drum's axis are arranged in a circumferential array. (After the wire end reaches the tipping station, the wire end surface is clamped by the roller components. A transmission assembly consisting of a drive device, a fourth gear, and a series of gears drives the drum to rotate. Simultaneously, the drum's rotation causes the roller components to rotate around the wire, thus tipping the wire.) Preferably, there are three rollers; using three rollers allows for better control of the wire feed. (Centered positioning), connected between the roll assembly and the rotating drum, is an adjusting component used to adjust the spacing between each group of roll shafts. (This invention can directly adjust the spacing between each group of roll shafts by means of the adjusting component—that is, under the drive of the first driving component, the first sliding component can slide radially in the radial sliding groove I on the front end wall of the rotating drum, and sequentially drive the roll shaft connected through the damping rotating shaft I and the second sliding component connected through the damping rotating shaft II to the rear end of the roll shaft and embedded in the inner wall of the sliding disk to move in the same direction. In this way, the adjustment of the tip diameter can be achieved without replacing different types of rolls.)Since the second driving component can drive the sliding disc to slide axially within the inner cavity of the rotating drum—that is, to cause the second sliding component embedded in the sliding disc to have an axial sliding tendency—and the length of the roll shaft is fixed, the second sliding component will inevitably move radially along the radial sliding groove II opened in the sliding disc. Thus, under the combined action of the first sliding component and the second driving component, the second sliding component will maintain radial movement in the same direction as the first sliding component while also creating a certain distance difference with it. In other words, this causes the axes of the roll shaft and the pressure cylinder outer sleeve on the rotating shaft surface to tilt—that is, adjust the wire tip angle. Therefore, using this invention, there is no need to replace different models of rolling mills. The roller can also adjust the tip angle to meet the different tip requirements of steel wires with large diameter differences, avoiding the cumbersome operation of roller replacement. It has the advantages of wide applicability, strong versatility, high tip-rolling efficiency, high tip-rolling quality, convenient use, and time and labor saving. The second drive component drives the sliding disc to slide axially in the inner cavity of the rotating drum to adjust the tip angle. (Using this invention, the tip diameter and tip angle can be adjusted without replacing different types of rollers, meeting the different tip requirements of steel wires with large diameter differences, avoiding the cumbersome operation of roller replacement, and has the advantages of wide applicability, strong versatility, high tip-rolling efficiency, high tip-rolling quality, convenient use, and time and labor saving.)

[0007] Each set of roller shafts consists of a rotating shaft and a pressure cylinder fitted over the surface of the rotating shaft (after the end of the steel wire reaches the tipping station, the end surface of the steel wire is clamped by at least three sets of roller shafts whose axes are parallel to the axis of the rotating drum, constituting the roller assembly; the rotation of the rotating drum drives the roller assembly to rotate around the steel wire—that is, the pressure cylinder in each set of roller shafts squeezes and rotates around the end of the steel wire to tip it); the adjusting component includes a first sliding component connected to the front end of the roller shaft via a damping rotating shaft I and embedded in the inner wall of the rotating drum, capable of sliding radially along the rotating drum. II. A second sliding component connected to the rear end of the roll shaft and embedded in the inner wall of the sliding disc, capable of sliding radially along the rotating drum, is used to drive a first driving component to slide radially along the first sliding component (under the drive of the first driving component, the first sliding component can slide radially along the radial sliding groove I on the front end wall of the rotating drum, thereby sequentially driving the roll shaft connected through the damping shaft I and the second sliding component connected to the rear end of the roll shaft and embedded in the inner wall of the sliding disc through the damping shaft II to move in the same direction, so that the adjustment of the tip diameter can be achieved without replacing different types of rolls).

[0008] The first sliding component is a cuboid structure, with a damping shaft mounting hole I machined at one end (for mounting the damping shaft I), and a helical protrusion machined on the front side of the other end (the helical protrusion matches the helical groove on the back of the first gear disk, and as the first gear disk rotates, it can drive the first sliding component to slide radially along the radial sliding groove I on the front end wall of the rotating cylinder); the second sliding component is an L-shaped block with a top cover, machined from a cuboid structure as the base and after removing a notch on the left side (the inner surface of the top cover is elastically supported by a first elastic element embedded in the radial sliding groove II, and the second sliding component slides radially away from each other under the assistance of the first elastic element), with a damping shaft mounting hole II machined at the small end (for mounting the damping shaft II); the first driving component includes components embedded in the front end of the rotating cylinder. The first gear of the first gear plate has three first gears arranged in a circumferential array that mesh with the front teeth of the first gear plate and are radially mounted on the front end wall of the rotating drum. The rear back of the first gear plate is machined with a spiral groove that matches the spiral protrusion of the first sliding component. (The rotation of the rotating drum drives the three first gears to rotate, which in turn drives the first gear plate to rotate through meshing. The spiral groove on the rear back of the first gear plate and the spiral protrusion on the front side of the first sliding component are used to drive the first sliding component to slide radially along the radial sliding groove I on the front end wall of the rotating drum. This drives the roll shaft connected by the damping shaft I and the second sliding component connected by the damping shaft II to the rear end of the roll shaft and embedded in the inner wall of the sliding plate to move in the same direction. In this way, the diameter of the rolling tip can be adjusted without changing different types of rolls.)The second driving component includes a fixed ring fitted into the rear end of the inner cavity of the rotating drum, a second gear disc fitted inside the inner cavity of the fixed ring, a recessed limiting groove machined at the center position of the second gear disc in the thickness direction, and a limiting protrusion matching the limiting groove on the inner surface of the fixed ring. Teeth are machined on both the rear end face and circumferential surface of the second gear disc. Three second gears, arranged in a circumferential array, mesh with the teeth on the rear end face of the second gear disc and radially penetrate the cavity wall of the fixed ring and the rear end wall of the rotating drum. Three third gears are mounted at the rear end of the threaded rod and mesh with the teeth on the circumferential surface. (The rotation of the rotating drum drives the fixed ring and the three second gears to rotate synchronously. Through meshing, they drive the second gear disc to rotate. The meshing of the teeth on the circumferential surface of the second gear disc with the third gears drives the threaded rod to rotate. Simultaneously, the rotation of the threaded rod causes the sliding disc to slide axially within the inner cavity of the rotating drum—that is, it causes the second sliding component embedded in the sliding disc to have an axial sliding tendency. Since the length of the roll shaft is fixed,...) This will cause the second sliding component to move radially along the radial sliding groove II opened in the sliding disk. Thus, under the combined action of the first sliding component and the second driving component, the second sliding component will maintain radial movement in the same direction as the first sliding component while also creating a certain distance difference with it. This means that the axis of the roll shaft and the pressure cylinder on the rotating shaft surface will tilt (i.e., the angle of the wire tip will be adjusted). A first elastic element is embedded in the sliding disk. The front end of the threaded rod is provided with a limiting plate embedded in the front wall of the rotating cylinder (the limiting plate axially limits the threaded rod, preventing it from sliding along the axis). The middle and rear ends of the threaded rod are threaded sections (used to match the threaded holes in the sliding disk, allowing the sliding disk to move axially as the threaded rod rotates). A second elastic element is fitted onto the non-threaded section of the threaded rod (because there is usually a gap between the threaded rod and the threaded hole, which can easily cause the sliding disk to become unstable; the second elastic element can improve the smoothness of the sliding disk).

[0009] The rotating cylinder described in this invention is composed of a hollow cylinder with a cylindrical outer surface and a two-step cylindrical inner cavity, and end plates connected by bolts. A ring groove for mounting the first gear disc is formed on the inner wall of the front end of the hollow cylinder. Three radial sliding grooves I, with cross-sections matching the first sliding component, are evenly distributed around the front end of the hollow cylinder (used to mount the first sliding component and serve as radial slideways for it). Three radial limiting holes I for the gear shaft, which are used to mount the gear shaft of the first gear and drive it to rotate synchronously with the rotating cylinder, are formed on the front end of the hollow cylinder. Three radial limiting holes II for the gear shaft, which are used to mount the gear shaft of the second gear and drive it to rotate synchronously with the rotating cylinder, are formed on the rear end of the hollow cylinder. Three slots for mounting limiting discs are formed on the back side of the front end of the hollow cylinder.

[0010] The sliding disk described in this invention is a hollow disk-shaped structure with a two-step column outer surface and a cylindrical cavity inner surface. Three radial sliding grooves II, with cross-sections matching the maximum cross-section of the second sliding component, are evenly distributed circumferentially on the large-diameter end face of the two-step column (used to embed the second sliding component and serve as radial slideways for the second sliding component). Three threaded holes for threaded rods are evenly distributed circumferentially on the large-diameter section of the two-step column. The outer diameter of the small-diameter section of the two-step column matches the inner diameter of the second gear disk (facilitating the fitting and positioning of the second gear disk). The first elastic element is embedded in the radial sliding grooves II and supported on the inner surface of the top cover of the second sliding component (the first elastic element can assist the second sliding component to slide radially in a direction away from each other).

[0011] The base described in this invention is composed of a bottom plate, a front upright plate, and a rear upright plate. A gear mounting groove for embedding the fourth gear is provided in the front upright plate, and a through hole for mounting the fourth gear shaft is provided in the rear upright plate. The fourth gear and the driving device are mounted at both ends of the fourth gear shaft (the driving force of the driving device is transmitted to the fourth gear through the fourth gear shaft). The fixing buckle is a circular column formed by two symmetrical semi-circular buckle bodies hooked together by a locking mechanism (on one hand, the fixing buckle supports the tipping device; on the other hand, the fixing buckle limits the left-right and up-down translational freedom of the tipping device; simultaneously, the fixing buckle, in conjunction with the semi-circular support, fixing clamp, and gear, can prevent the tipping device from moving back and forth or swinging left and right). The inner surface of the fixing buckle is machined with... A ring groove is used to mount the gear (to limit the axial translational freedom of the gear, effectively preventing axial movement of the gear, drum, and roll components). The lower semi-circular fastener is fixed to the top of the front upright plate. At the two ends of the semi-circular support, a fixed clamp with a central angle of 30 degrees is engaged by a locking hinge (the semi-circular support is used to support the tipping device; the semi-circular support and the fixed clamp are used to limit the left-right and up-down translational freedom of the tipping device; at the same time, the semi-circular support, the fixed clamp, and the fixed buckle are used to prevent the tipping device from swinging left and right). Rollers that can rotate on the surface of the drum are embedded at the end of the fixed clamp and in the upper middle part of the semi-circular support (to reduce friction on the base during the rotation of the drum). The semi-circular support is fixed to the top of the rear upright plate.

[0012] The feeding device described in this invention includes a feeding bracket (for mounting horizontal conveying rollers, a third elastic element, and a slider), two horizontal conveying rollers that can slide up and down (with an automatic height adjustment function to ensure that the steel wire to be rolled is coaxially arranged with the drum and rolling mill components, facilitating the centered positioning of the steel wire), and a third elastic element and slider installed at both ends of the horizontal conveying rollers to push the two horizontal conveying rollers closer to each other (to adjust the height of the horizontal conveying rollers, i.e., to adjust the center height of the steel wire to be rolled).

[0013] The driving device described in this invention is a forward and reverse motor (the forward or reverse rotation of the motor drives the drum to rotate forward or reverse accordingly, thereby controlling the roll components to move radially outward or radially inward, thus achieving adjustment of the roll tip diameter).

[0014] The design principle of this invention is as follows:

[0015] This invention allows for adjustment of the tip diameter and tip angle without replacing different types of rolls, meeting the varying tip requirements of steel wires with large diameter differences. It avoids the cumbersome roll replacement process and offers advantages such as wide applicability, strong versatility, high tipping efficiency, high tipping quality, ease of use, and time and labor savings. More specifically, this invention includes a coaxially arranged feeding device and a tipping device. The tipping device comprises a rotating drum with a gear ring around its front end, roll components arranged circumferentially within the drum's inner cavity, consisting of at least three sets of roll shafts with axes parallel to the drum's axis, an adjusting component for adjusting the spacing between the roll shafts, and a second driving component that drives a sliding disc to slide axially within the drum's inner cavity to adjust the tip angle. The tipping principle of this invention: This invention uses a feeding device to horizontally transport the end of the steel wire forward to the tipping station in the tipping device. Upon reaching the tipping station, the surface of the steel wire end is clamped by the roller component. The transmission component drives the drum to rotate, and the rotation of the drum in turn drives the roller component to rotate around the steel wire, thus tipping the steel wire. The tipping diameter adjustment principle of this invention: This invention uses an adjustment component to adjust the spacing between each set of roller shafts. Specifically, under the drive of the first driving component, the first sliding component can slide radially in the radial sliding groove I on the front end wall of the drum. This sequentially drives the roller shaft connected through damping shaft I, and the second sliding component connected through damping shaft II to the rear end of the roller shaft and embedded in the inner wall of the sliding disc to move in the same direction. This allows for tipping diameter adjustment without changing different types of rollers, meeting the different tipping requirements of steel wires with large diameter differences. It avoids the cumbersome operation of changing rollers and has the advantages of wide applicability, strong versatility, high tipping efficiency, high tipping quality, convenient use, and time and labor saving. The principle of tip angle adjustment in this invention—This invention also includes a second driving component, which drives the sliding disc to slide axially within the inner cavity of the rotating drum. This causes the second sliding component, embedded in the sliding disc, to have an axial sliding tendency. Since the length of the roll shaft is fixed, the second sliding component will inevitably move radially along the radial sliding groove II opened in the sliding disc. Thus, under the combined action of the first sliding component and the second driving component, the second sliding component will maintain radial movement in the same direction as the first sliding component while also creating a certain distance difference with it. This means that the axes of the roll shaft and the pressure cylinder outer sleeve on the rotating shaft surface will tilt—that is, the tip angle of the steel wire will be adjusted. This allows for tip angle adjustment without changing different types of rolls, meeting the different tip requirements of steel wires with large diameter differences. It avoids the cumbersome operation of roll replacement and has the advantages of wide applicability, strong versatility, high tipping efficiency, high tipping quality, convenient use, and time and labor saving.

[0016] The beneficial technical effects of the present invention are as follows:

[0017] This invention allows for the adjustment of the tip diameter and tip angle without the need to replace different types of rolls, meeting the different tip requirements of steel wires with large diameter differences. It avoids the cumbersome operation of changing rolls and has the advantages of wide applicability, strong versatility, high tip rolling efficiency, high tip rolling quality, convenient use, and time and labor saving.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 11As shown, the present invention provides a wire tipping machine capable of adjusting the tip diameter and tip angle, comprising a feeding device 3 and a tipping device 2 arranged collinearly along the forward direction of the wire 4 (the present invention uses the feeding device 3 to horizontally and forwardly transport the end of the wire 4 to the tipping station in the tipping device 2; upon reaching the tipping station, the end surface of the wire 4 is clamped by the roller component 2-2, and the transmission component drives the rotating drum 2-1 to rotate, which in turn drives the roller component 2-2 to rotate around the wire to tip it), and a base 1 supported below the tipping device by means of a fixing buckle 8, a semi-circular support 9, and a fixing clamp 10 (the base 1 is used to support the tipping device 2; the fixing buckle 8, semi-circular support 9, and fixing clamp 10 are used to tip the wire). In addition to supporting the tipping device 2, it also limits the left and right translational degrees of freedom and the up and down translational degrees of freedom of the tipping device 2, and prevents the tipping device 2 from moving back and forth and swinging left and right. It is a transmission component that can drive the tipping device 2 to rotate, consisting of the drive device 7, the fourth gear 6, and the gear 5 connected in sequence (the drive device 7 drives the fourth gear 6 to rotate, the fourth gear 6 meshes with the gear 5 and drives the rotating drum 2-1 to rotate, and the rotation of the rotating drum 2-1 drives the rolling mill component 2-2 to rotate around the steel wire to tip the steel wire); the tipping device 2 includes a rotating drum 2-1 with the gear 5 ringed around the front end of the outer surface (the rotating drum 2-1 rotates through the meshing of the gear 5 and the fourth gear 6), and an inner sleeve on the rear half of the rotating drum 2-1. The sliding disk 2-4 of the cavity contains a roller assembly 2-2 arranged in a circumferential array within the inner cavity of the rotating drum. This assembly consists of at least three sets of roller shafts 2-2-1 with axes parallel to the rotating drum axis. (After the end of the steel wire 4 reaches the tipping station, the end surface of the steel wire 4 is clamped by the roller assembly 2-2. A transmission assembly consisting of a drive device 7, a fourth gear 6, and a gear 5 connected in sequence drives the rotating drum 2-1 to rotate. Simultaneously, the rotating drum 2-1 rotates, causing the roller assembly 2-2 to rotate around the steel wire for tipping. Preferably, there are three roller shafts 2-2-1, as this allows for better centering of the steel wire 4.) The roller assembly 2-2 is connected to the rotating drum 2-1. The present invention uses the adjusting component 2-3 to adjust the spacing of each group of roll shafts 2-2-1. The adjusting component 2-3 can directly adjust the spacing of each group of roll shafts 2-2-1. That is, under the drive of the first driving component 2-3-3, the first sliding component 2-3-1 can slide radially in the radial sliding groove I2-1-1-2 on the front end wall of the rotating drum 2-1, and sequentially drive the roll shaft 2-2-1 connected by the damping rotating shaft I2-6 and the second sliding component 2-3-2 connected to the rear end of the roll shaft 2-2-1 and embedded in the inner wall of the sliding disk 2-4 to move in the same direction. In this way, the adjustment of the tip diameter can be achieved without replacing different types of rolls.Since the second driving component 2-5 can drive the sliding disk 2-4 to slide axially within the inner cavity of the rotating drum 2-1—that is, to drive the second sliding component 2-3-2 embedded in the sliding disk 2-4 to have an axial sliding tendency—and the length of the roll shaft 2-2-1 is fixed, the second sliding component 2-3-2 will inevitably move radially along the radial sliding groove II 2-4-1 opened in the sliding disk 2-4. Thus, under the combined action of the first sliding component 2-3-1 and the second driving component 2-5, the second sliding component 2-3-2 will maintain radial movement in the same direction as the first sliding component 2-3-1 while also creating a certain distance difference with the first sliding component 2-3-1. In other words, this causes the axes of the roll shaft 2-2-1 and the pressure cylinder 2-2-1-2 wrapped around the rotating shaft surface to tilt. The slant—that is, adjusting the tip angle of the steel wire—allows the adjustment of the tip angle without replacing different types of rolls, meeting the different tip requirements of steel wires with large diameter differences. This avoids the cumbersome roll replacement process and offers advantages such as wide applicability, strong versatility, high tipping efficiency, high tipping quality, ease of use, and time and labor saving. The second drive component 2-5 (which drives the sliding disc 2-4 to slide axially within the inner cavity of the rotating drum 2-1, adjusting the tip angle) allows the adjustment of both the tip diameter and tip angle without replacing different types of rolls, meeting the different tipping requirements of steel wires with large diameter differences. This avoids the cumbersome roll replacement process and offers advantages such as wide applicability, strong versatility, high tipping efficiency, high tipping quality, ease of use, and time and labor saving.

[0032] Each set of roller shafts 2-2-1 consists of a rotating shaft 2-2-1-1 and a pressure cylinder 2-2-1-2 sleeved on the surface of the rotating shaft (after the end of the steel wire 4 reaches the tipping station, the end surface of the steel wire 4 is clamped by at least three sets of roller shafts 2-2-1 whose axes are parallel to the axis of the rotating drum, constituting the roller component 2-2; the rotating drum 2-1 rotates, driving the roller component 2-2 to rotate around the steel wire—that is, the pressure cylinder 2-2-1-2 in each set of roller shafts 2-2-1 squeezes and rotates around the end of the steel wire 4 to tip the steel wire); the adjusting component 2-3 includes a first sliding component 2-3-1 connected to the front end of the roller shaft 2-2-1 via a damping rotating shaft I 2-6 and embedded in the inner wall of the rotating drum 2-1, which can slide radially along the rotating drum, and a damping rotating shaft II 2... -7 The second sliding component 2-3-2, which is connected to the rear end of the roll shaft 2-2-1 and embedded in the inner wall of the sliding disk 2-4, can slide radially along the drum. It is used to drive the first driving component 2-3-3, which drives the first sliding component 2-3-1 to slide radially. (Under the drive of the first driving component 2-3-3, the first sliding component 2-3-1 can slide radially in the radial sliding groove I2-1-1-2 on the front end wall of the drum 2-1, which in turn drives the roll shaft 2-2-1 connected by the damping shaft I2-6 and the second sliding component 2-3-2, which is connected to the rear end of the roll shaft 2-2-1 and embedded in the inner wall of the sliding disk 2-4 by the damping shaft II2-7, to move in the same direction. In this way, the diameter of the roll tip can be adjusted without replacing different types of rolls.)

[0033] The first sliding component 2-3-1 has a cuboid structure. One end is machined with a damping shaft mounting hole I2-3-1-1 (for mounting the damping shaft I2-6), and the other end has a helical protrusion 2-3-1-2 on its front side (the helical protrusion 2-3-1-2 is used to mate with the helical groove 2-3-3-2 on the back of the first gear disk 2-3-3-1, and as the first gear disk 2-3-3-1 rotates, it can drive the first sliding component 2-3-1 to slide radially along the radial sliding groove I2-1-1-2 on the front end wall of the rotating cylinder 2-1); the second sliding component 2-3 -2 is an L-shaped block with a top cover 2-3-2-2, machined after removing a notch on the left side, based on a cuboid structure (the inner surface of the top cover 2-3-2-2 is elastically supported by a first elastic element 2-5-8 embedded in a radial sliding groove II 2-4-1, and the second sliding component 2-3-2 slides radially away from each other under the assistance of the first elastic element 2-5-8). A damping shaft mounting hole II 2-3-2-1 (for mounting the damping shaft II 2-7) is machined at the small end; the first driving component 2-3-3 includes a first... The gear disk 2-3-3-1 has three first gears 2-3-3-3 arranged in a circumferential array to mesh with the front teeth of the first gear disk 2-3-3-1 and are radially mounted on the front end wall of the rotating cylinder. The rear back of the first gear disk 2-3-3-1 is machined with a helical groove 2-3-3-2 that matches the helical protrusion 2-3-1-2 of the first sliding component 2-3-1. (The rotation of the rotating cylinder 2-1 drives the three first gears 2-3-3-3 to rotate, which in turn drives the first gear disk 2-3-3-1 to rotate through meshing. The helical groove 2-3-3-2 on the rear back of the first gear disk 2-3-3-1 further drives the rotation of the first gear disk 2-3-3-1.) The interaction between the spiral groove 2-3-3-2 and the spiral protrusion 2-3-1-2 on the front side of the first sliding component 2-3-1 causes the first sliding component 2-3-1 to slide radially along the radial sliding groove I 2-1-1-2 on the front end wall of the rotating drum 2-1. This, in turn, causes the roll shaft 2-2-1 connected by the damping shaft I 2-6 and the second sliding component 2-3-2 connected to the rear end of the roll shaft 2-2-1 and embedded in the inner wall of the sliding disk 2-4 by the damping shaft II 2-7 to move in the same direction. This allows for adjustment of the tip diameter without replacing different types of rolls.The second driving component 2-5 includes a fixing ring 2-5-1 fitted into the rear end of the inner cavity of the rotating drum, and a second gear disk 2-5-2 fitted inside the inner cavity of the fixing ring 2-5-1. A recessed limiting groove 2-5-3 is machined at the center position in the thickness direction of the second gear disk 2-5-2. A limiting protrusion 2-5-4 matching the limiting groove 2-5-3 is provided on the inner cavity surface of the fixing ring 2-5-1. Teeth are machined on both the rear end face and the circumferential surface of the second gear disk 2-5-2, meshing with the teeth on the rear end face of the second gear disk 2-5-2 in a circumferential array and radially penetrating the cavity wall of the fixing ring. The three second gears 2-5-5 on the rear end wall of the rotating drum, and the three third gears 2-5-7 installed at the rear end of the threaded rod 2-5-6 and meshing with the teeth on the circumferential surface (the rotation of the rotating drum 2-1 drives the fixed ring 2-5-1 and the three second gears 2-5-5 to rotate synchronously, which in turn drives the second gear disk 2-5-2 to rotate, and the meshing of the teeth on the circumferential surface of the second gear disk 2-5-2 with the third gears 2-5-7 drives the threaded rod 2-5-6 to rotate, and the rotation of the threaded rod 2-5-6 drives the sliding disk 2-4 to slide axially in the inner cavity of the rotating drum 2-1—that is, drives the embedded The second sliding component 2-3-2, installed in the sliding disk 2-4, has an axial sliding tendency. Since the length of the roll shaft 2-2-1 is fixed, the second sliding component 2-3-2 will inevitably move radially along the radial sliding groove Ⅱ2-4-1 opened in the sliding disk 2-4. Thus, under the combined action of the first sliding component 2-3-1 and the second driving component 2-5, the second sliding component 2-3-2 will maintain radial movement in the same direction as the first sliding component 2-3-1 while also creating a certain distance difference with it. In other words, this allows the roll shaft 2-2-1 and the outer sleeve... The axis of the pressure cylinder 2-2-1-2 on the rotating shaft surface is tilted (i.e., the angle of the wire tip is adjusted), and the first elastic element 2-5-8 is embedded in the sliding disc 2-4. The front end of the threaded rod 2-5-6 is provided with a limiting disc 2-5-6-1 embedded in the front wall of the rotating cylinder 2-1 (the limiting disc 2-5-6-1 axially limits the threaded rod 2-5-6, preventing the threaded rod 2-5-6 from sliding along the axial direction). The middle and rear ends of the threaded rod 2-5-6 are threaded sections 2-5-6-2 (used in conjunction with the threaded hole 2-4-2 in the sliding disc 2-4, which, along with the threaded rod 2-5-6...). The rotation of the screw can drive the sliding disk 2-4 to move axially. A second elastic element 2-5-6-3 is fitted onto the non-threaded section of the threaded rod 2-5-6 (because there is usually a gap between the threaded rod 2-5-6 and the threaded hole 2-4-2, which can easily cause the sliding disk 2-4 to become unstable; the second elastic element 2-5-6-3 can improve the smoothness of the sliding of the sliding disk 2-4).

[0034] The rotating cylinder 2-1 described in this invention is formed by bolting together a hollow cylinder 2-1-1 with a cylindrical outer surface and a two-step cylindrical inner cavity, and end plates 2-1-2. A ring groove 2-1-1-1 for mounting the first toothed disc 2-3-3-1 is formed on the inner wall of the hollow cylinder 2-1-1 at the front end. Three radial sliding grooves Ⅰ2-1-1-2 (for mounting the first sliding component 2-3-1 and serving as radial tracks for the first sliding component 2-3-1) are evenly distributed circumferentially on the front wall of the hollow cylinder 2-1-1. Three radial limiting holes Ⅰ2-1-1-3 for gear shafts that mate with the first gear 2-3-3-3 are provided on the wall (for the gear shaft of the first gear 2-3-3-3 to pass through and drive the first gear 2-3-3-3 to rotate synchronously with the rotating drum 2-1). Three radial limiting holes Ⅱ2-1-1-4 for gear shafts that mate with the second gear 2-5-5 are provided on the rear wall of the hollow cylinder 2-1-1 (for the gear shaft of the second gear 2-5-5 to pass through and drive the second gear 2-5-5 to rotate synchronously with the rotating drum 2-1). Three slots 2-1-1-5 for embedding the limiting disc 2-5-6-1 are provided on the back side of the front wall of the hollow cylinder 2-1-1.

[0035] The sliding disk 2-4 described in this invention is a hollow disk-shaped structure with a two-step column outer surface and a cylindrical cavity inner surface. Three radial sliding grooves II 2-4-1 with cross-sections matching the maximum cross-section of the second sliding component 2-3-2 are evenly distributed circumferentially on the large-diameter end face of the two-step column (used to embed the second sliding component 2-3-2 and serve as radial slideways for the second sliding component 2-3-2). Three threaded holes 2-4-2 for threading the threaded rod 2-5-6 are evenly distributed circumferentially on the large-diameter section of the two-step column. The outer diameter of the small-diameter section of the two-step column matches the inner diameter of the second gear disk 2-5-2 (facilitating the fitting and positioning of the second gear disk 2-5-2). The first elastic element 2-5-8 is embedded in the radial sliding groove II 2-4-1 and supported on the inner surface of the top cover 2-3-2-2 of the second sliding component 2-3-2 (the first elastic element 2-5-8 can assist the second sliding component 2-3-2 to slide radially away from each other).

[0036] The base 1 described in this invention is composed of a bottom plate 1-1, a front upright plate 1-2, and a rear upright plate 1-3. A gear mounting groove 1-2-1 for embedding the fourth gear 6 is provided in the front upright plate 1-2, and a through hole 1-3-1 for passing through the fourth gear shaft 6-1 is provided in the rear upright plate 1-3. The fourth gear 6 and the driving device 7 are mounted at both ends of the fourth gear shaft 6-1 (the driving force of the driving device 7 is transmitted to the fourth gear 6 through the fourth gear shaft 6-1). The fixing buckle 8 is a circular column formed by two symmetrical semi-circular buckle bodies 8-1 connected by a locking hinge (on one hand, the fixing buckle 8 supports the tipping device 2; on the other hand, the fixing buckle 8 limits the left-right and up-down translational freedom of the tipping device 2; simultaneously, the fixing buckle 8, in conjunction with the semi-circular support 9, the fixing clamp 10, and the gear 5, can prevent the tipping device 2 from moving back and forth or swinging left and right). The inner surface of the fixing buckle 8... The surface is machined with a ring groove 8-2 for mounting the gear 5 (used to limit the axial translational freedom of the gear 5, effectively preventing the axial movement of the gear 5, the rotating drum 2-1, and the rolling mill component 2-2). The lower semi-circular buckle 8-1 is fixed to the top of the front upright plate 1-2. At the two top ends of the semi-circular support 9, a fixed clamp 10 with a central angle of 30 degrees is hooked together by a locking hinge (the semi-circular support 9 is used to support the tipping device 2; the semi-circular support 9 and the fixed clamp 10 are used together to limit the left and right translational freedom and the up and down translational freedom of the tipping device 2; at the same time, the semi-circular support 9, the fixed clamp 10 and the fixed buckle 8 are used together to prevent the tipping device 2 from swinging left and right). Rollers 11 that can rotate on the surface of the rotating drum 2-1 are embedded at the end of the fixed clamp 10 and the upper middle part of the semi-circular support 9 (which can reduce the friction of the rotating drum 2-1 on the base 1 during its rotation). The semi-circular support 9 is fixed to the top of the rear upright plate 1-3.

[0037] The feeding device 3 described in this invention includes a feeding bracket 3-1 (for mounting horizontal conveying rollers 3-2, a third elastic element, and a slider 3-3), two horizontal conveying rollers 3-2 that can slide up and down (with an automatic height adjustment function to ensure that the steel wire 4 to be rolled is coaxially arranged with the rotating drum 2-1 and the rolling mill component 2-2, which facilitates the centered positioning of the steel wire 4), and a third elastic element and slider 3-3 installed at both ends of the horizontal conveying rollers 3-2 to push the two horizontal conveying rollers 3-2 closer to each other (to adjust the height of the horizontal conveying rollers 3-2, i.e., to adjust the center height of the steel wire 4 to be rolled).

[0038] The driving device 7 described in this invention is a forward and reverse motor (the forward or reverse rotation of the motor drives the rotating drum 2-1 to rotate forward or reverse accordingly, thereby controlling the roller component 2-2 to move radially outward or radially inward, thus achieving adjustment of the tip diameter).

[0039] The specific uses of this invention are as follows:

[0040] Before use, assemble the invention according to the structural positional relationship shown in the above structural description and attached drawings. After assembly, it can be used normally—first, let the end of the steel wire 4 to be tipped pass through the center of the gap between the upper and lower horizontal conveying rollers 3-2 of the feeding device 3 and extend forward to the tipping station; then, adjust the tipping diameter according to the actual specifications of the steel wire 4—that is, adjust the spacing of each set of roller shafts 2-2-1 with the help of the adjusting component 2-3. Specifically, the rotation of the drum 2-1 drives the three first gears 2-3-3-3 to rotate, which in turn drives the first gear disc 2-3-3-1 to rotate through meshing, and then the spiral groove 2 on the back of the first gear disc 2-3-3-1 rotates. The engagement of the spiral protrusion 2-3-1-2 on the front side of the first sliding component 2-3-1 with the first sliding component 2-3-1 causes the first sliding component 2-3-1 to slide radially along the radial sliding groove Ⅰ2-1-1-2 on the front end wall of the rotating drum 2-1. This sequentially drives the roll shaft 2-2-1 connected by the damping shaft Ⅰ2-6 and the second sliding component 2-3-2, which is connected to the rear end of the roll shaft 2-2-1 and embedded in the inner wall of the sliding disk 2-4, to move in the same direction. In this way, the diameter of the roll tip can be adjusted without replacing different types of rolls.

[0041] Next, the tipping angle is adjusted according to the tipping requirements of the steel wire 4. The second drive component 2-5 can drive the sliding disc 2-4 to slide axially within the inner cavity of the rotating drum 2-1. Specifically, the rotation of the rotating drum 2-1 drives the fixed ring 2-5-1 and the three second gears 2-5-5 to rotate synchronously. Through meshing, they drive the second gear disc 2-5-2 to rotate. The teeth on the circumferential surface of the second gear disc 2-5-2 mesh with the third gear 2-5-7 to drive the threaded rod 2-5-6 to rotate. While the threaded rod 2-5-6 rotates, it drives the sliding disc 2-4 to slide axially within the inner cavity of the rotating drum 2-1, that is, it drives the second sliding component 2-4 embedded in the sliding disc 2-4. -3-2 has an axial sliding tendency, and the length of the roll shaft 2-2-1 is fixed. Therefore, the second sliding component 2-3-2 will move radially along the radial sliding groove Ⅱ2-4-1 opened in the sliding disk 2-4. In this way, under the combined action of the first sliding component 2-3-1 and the second driving component 2-5, the second sliding component 2-3-2 will maintain the same radial movement as the first sliding component 2-3-1, while also creating a certain distance difference with the first sliding component 2-3-1. That is to say, the axis of the roll shaft 2-2-1 and the pressure cylinder 2-2-1-2 wrapped on the rotating shaft surface will be tilted - that is, the wire tip angle will be adjusted.

[0042] Finally, the end of the steel wire 4 is tipped – the surface of the end of the steel wire 4 at the tipping station is covered by the clamp of the roller component 2-2. The transmission assembly is started, and the drive device 7 drives the fourth gear 6 to rotate. After the fourth gear 6 meshes with the gear 5, it drives the rotating drum 2-1 to rotate. The rotation of the rotating drum 2-1 drives the roller component 2-2 to rotate around the steel wire to tip the steel wire.
