Description

Technical Field

[0001] This invention application relates to the field of steel wire processing technology, specifically to a steel wire tipping machine with an adjustable function. Background Technology

[0002] As a core auxiliary equipment in metal wire drawing, the tipping mill's main function is to roll the ends of metal wires, such as steel wires, into pointed shapes so that they can pass smoothly through the drawing die holes for subsequent drawing operations. With the increasing demands for product precision, processing efficiency, and adaptability in the steel wire processing industry, existing tipping mills have gradually revealed many shortcomings in terms of the rationality, accuracy, and coordination of tipping diameter and angle adjustments.

[0003] Patent application CN202310863307.3 discloses a wire tipping machine capable of adjusting the tip diameter and tip angle. Its working principle is as follows: after the wire end is conveyed to the tipping station by the feeding device, the rotating drum is driven to rotate by the drive device. The rotating drum drives the first sliding component to slide radially through the gear-gear disk transmission, thereby driving the roller shaft to move in the same direction to adjust the tip diameter. At the same time, the second drive component drives the sliding disk to slide axially, so that a distance difference is generated between the two ends of the roller shaft, thereby realizing the adjustment of the tip angle. It can adapt to the processing needs of wires with different diameters without changing the rollers.

[0004] Although the above solution achieves adjustable diameter and angle of the rolling tip, it still has the following problems: diameter and angle adjustment rely on two independent transmission systems. The diameter is adjusted by the first drive component and the angle is adjusted by the second drive component. The two need to be operated step by step, making the adjustment process cumbersome. Moreover, there is strong coupling in the adjustment process. When adjusting the angle alone, it is easy to change the roll spacing. Repeated calibration is required to achieve the preset requirements. In addition, the adjustment mechanism adopts a multi-stage transmission structure of gears, gear discs, spiral grooves, and threaded rods. The transmission chain is long, and gear meshing clearance and thread fit clearance can easily lead to deviations in adjustment accuracy, affecting the quality of the rolling tip. Summary of the Invention

[0005] To address the aforementioned issues, a wire tipping mill with adjustable functions is provided. By setting up a rotating drum, a roll group, a linkage adjustment mechanism, and a bidirectional drive mechanism, the synchronous adjustment of the tip diameter and angle can be achieved.

[0006] To address the problems of existing technologies, this invention provides a wire tipping mill with an adjustable function, comprising a rotating drum, a roll assembly, a linkage adjustment mechanism, and a bidirectional drive mechanism. The roll assembly includes at least two rolls arranged symmetrically around the axis of the rotating drum, with a first bearing seat and a second bearing seat connected to each end of the rolls. The linkage adjustment mechanism is the same number as and corresponds one-to-one with the rolls. Each linkage adjustment mechanism includes a fixed base, a sliding rod, two sliders, a first adjustment component, and a second adjustment component. The fixed base is disposed on the inner wall of the rotating drum. The middle portion of the sliding rod is connected to the fixed base, and the sliding rod is parallel to the axis of the rotating drum. The two sliders are slidably disposed at both ends of the sliding rod, and the sliders are drively connected to the first adjustment component and the second adjustment component. The first adjustment component adjusts the distance between the rolls and the axis of the rotating drum, and the second adjustment component adjusts the angle between the rolls and the axis of the rotating drum. The bidirectional drive mechanism drives the two sliders to move along the sliding rod.

[0007] Preferably, the first adjusting assembly includes a lower plate, two short connecting rods, and a first guide rod; the lower plate is connected to the first bearing seat; the two short connecting rods are respectively hinged to the two sliders, and the short connecting rods are hinged to the lower plate; the first guide rod passes vertically through the lower plate and is connected to the fixed seat.

[0008] Preferably, the second adjusting assembly includes an upper plate and two long connecting rods; one end of the upper plate is provided with a sliding connecting assembly for connecting the second bearing seat; the two long connecting rods are respectively hinged to the two sliders, and the long connecting rods are hinged to the upper plate.

[0009] Preferably, the sliding connection assembly includes a first limiting sleeve and a second guide rod; the first limiting sleeve is disposed on the lower plate; the second guide rod passes vertically through the first limiting sleeve, and the two ends of the second guide rod are respectively connected to the second bearing seat and the upper plate.

[0010] Preferably, the sliding connection assembly further includes an elastic reset member, which is used to provide an elastic force to the second guide rod in a direction away from the lower plate.

[0011] Preferably, the second adjustment component further includes a balancing component, the balancing component and the sliding connection component are respectively disposed at both ends of the upper plate, and the balancing component is used to maintain the balance of the upper plate.

[0012] Preferably, a sliding sleeve is provided at one end of the roll, and the sliding sleeve is used to connect the second bearing seat and the roll.

[0013] Preferably, the bidirectional drive mechanism includes two annular transmission plates and a drive assembly; the two annular transmission plates are respectively disposed at both ends of the rotating drum, and the annular transmission plates are connected to the slider; the drive assembly is used to drive the two annular transmission plates to move towards or away from each other.

[0014] Preferably, there are at least two drive components, and the two drive components are arranged outside the rotating drum around the axis of the rotating drum.

[0015] Preferably, the driving assembly includes a rolling assembly that abuts against the annular transmission plate to reduce friction between the driving assembly and the annular transmission plate.

[0016] The advantages of this invention application compared to the prior art are:

[0017] 1. This invention application sets up a rotating drum, a roll group, a linkage adjustment mechanism, and a bidirectional drive mechanism. Multiple rolls are symmetrically arranged around the axis of the rotating drum. The bidirectional drive mechanism drives the sliders at both ends of the slide rods in each linkage adjustment mechanism to move closer to each other along the slide rods. During the movement of the sliders, on the one hand, the first adjustment component synchronously drives the corresponding rolls to translate towards the axis of the rotating drum, gradually clamping the ends of the steel wire to adapt to the required tip diameter. On the other hand, the second adjustment component causes the ends of the rolls to generate relative displacement, changing the roll axis from parallel to the axis of the rotating drum to intersecting, thus adjusting the tip angle. Under the synergistic effect of the rotating drum driving the rolls to revolve and the rolls clamping the steel wire while maintaining the set tilt angle, the tip processing of the steel wire ends is completed. By linking the first and second adjustment components with the same slider, the synchronous adjustment of the tip diameter and angle is achieved, eliminating the need for step-by-step operation and simplifying the adjustment process.

[0018] 2. This invention application sets up a lower plate, two short connecting rods and a first guide rod. Through the symmetrical hinge design of the short connecting rods and the rigid guiding constraint of the first guide rod, the precise translation of the roll along the fixed diameter direction of the drum is realized, which effectively avoids the problem of radial offset or swaying when the roll moves, and ensures that the distance between the roll and the axis of the drum is precisely controllable, thereby ensuring the consistency of the diameter of the steel wire tip and the processing accuracy.

[0019] 3. This invention comprises an upper plate, two long connecting rods, and a sliding connection assembly. The slider generates a thrust on the long connecting rods through the hinge point. The two long connecting rods synchronously transmit a symmetrical downward force to the upper plate, causing the upper plate to smoothly move downward along a preset direction. One end of the upper plate drives the second bearing seat to move downward synchronously through the sliding connection assembly, while the first bearing seat at the other end of the roll remains in a predetermined position with the lower plate, making the distance between the second bearing seat and the lower plate greater than the distance between the first bearing seat and the upper plate. The roll axis changes from being parallel to the drum axis to being inclined, thus completing the adjustment of the roll tip angle. Through the symmetrical transmission of the long connecting rods and the linkage of the upper plate, the adjustment of the roll angle is realized without the need for an additional independent drive mechanism.

Detailed Implementation

[0033] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 12As shown: A wire tipping mill with adjustment function includes a rotating drum 1, a set of rolls 2, a linkage adjustment mechanism 3, and a bidirectional drive mechanism 4; the set of rolls 2 includes at least two rolls 2, which are symmetrically arranged around the axis of the rotating drum 1, and the two ends of each roll 2 are respectively connected to a first bearing seat 21 and a second bearing seat 22; the linkage adjustment mechanism 3 is the same number as the rolls 2 and corresponds one-to-one, and the linkage adjustment mechanism 3 includes a fixed seat 31, a slide bar 32, two sliders 33, a first adjustment component 34, and a second adjustment component 35, and the fixed seat 31 is disposed on the rotating drum 1. On the inner wall, the middle part of the slide rod 32 is connected to the fixed seat 31, and the slide rod 32 is parallel to the axis of the rotating drum 1. The two sliders 33 are respectively slidably disposed at both ends of the slide rod 32. The sliders 33 are kinetically connected to the first adjusting component 34 and the second adjusting component 35. The first adjusting component 34 is used to adjust the distance between the axis of the roller 2 and the axis of the rotating drum 1, and the second adjusting component 35 is used to adjust the included angle between the axis of the roller 2 and the axis of the rotating drum 1. The bidirectional drive mechanism 4 is used to drive the two sliders 33 to move along the slide rod 32.

[0035] In this embodiment, the roll group 2 includes three rolls 2. Initially, the three rolls 2 are far apart from each other, forming a central space for inserting steel wire, and the axis of the rolls 2 is parallel to the axis of the rotating drum 1. During operation, the end of the pointed steel wire to be rolled is first inserted into the central area surrounded by the three rolls 2; then the rotating drum 1 starts to rotate around its own axis, and the three rolls 2 are synchronously driven to revolve around the axis of the rotating drum 1 through the linkage adjustment mechanism 3. Simultaneously, the bidirectional drive mechanism 4 is activated, driving the sliders 33 at both ends of the slide bar 32 in each linkage adjustment mechanism 3 to move closer to each other along the slide bar 32. During the movement of the sliders 33, on the one hand, the first adjustment component 34 synchronously drives the corresponding roller 2 to translate towards the axis of the rotating drum 1, gradually clamping the end of the steel wire to adapt to the required tip diameter; on the other hand, the second adjustment component 35 causes relative displacement at both ends of the roller 2, changing the axis of the roller 2 from parallel to the axis of the rotating drum 1 to intersecting, adjusting the tip angle. Under the synergistic effect of the rotating drum 1 driving the roller 2 to revolve and the roller 2 clamping the steel wire while maintaining the set tilt angle, the tipping of the steel wire is completed. The synchronous adjustment of diameter and angle is achieved by driving the first adjustment component 34 and the second adjustment component 35 in linkage with the same slider 33.

[0036] Reference Figure 4 , Figure 5 and Figure 6As shown: The first adjustment assembly 34 includes a lower plate 341, two short connecting rods 342 and a first guide rod 343; the lower plate 341 is connected to the first bearing seat 21; the two short connecting rods 342 are respectively hinged to the two sliders 33, and the short connecting rods 342 are hinged to the lower plate 341; the first guide rod 343 penetrates the lower plate 341 vertically and is connected to the fixed seat 31.

[0037] When the bidirectional drive mechanism 4 is activated, it drives the two sliders 33 to approach each other along the slide bar 32. The sliders 33 apply a thrust to the short connecting rod 342 through the hinge point. The two short connecting rods 342 synchronously transmit the thrust to the lower plate 341, forming a symmetrical downward force. Under the action of the thrust, the lower plate 341 moves downward along the axis of the first guide rod 343. The first guide rod 343 restricts the lower plate 341 to move only in a fixed direction perpendicular to the axis of the rotating drum 1. At the same time, the symmetrically distributed short connecting rods 342 continuously provide a balanced thrust, preventing the lower plate 341 from deviating or tilting during movement, and ensuring that the lower plate 341 drives the roller 2 to move smoothly along the preset fixed diameter direction. By using the symmetrical hinge design of the short connecting rod 342 and the rigid guiding constraint of the first guide rod 343, the roll 2 can be accurately translated along the fixed diameter direction of the drum 1. This effectively avoids the problem of radial offset or swaying when the roll 2 moves, ensuring that the distance between the roll 2 and the axis of the drum 1 is accurately and controllable, thereby ensuring the consistency of the wire tip diameter and the processing accuracy.

[0038] Reference Figure 4 , Figure 5 and Figure 7 As shown: The second adjustment component 35 includes an upper plate 351 and two long connecting rods 352; one end of the upper plate 351 is provided with a sliding connection component 353 connecting the second bearing seat 22; the two long connecting rods 352 are respectively hinged to the two sliders 33, and the long connecting rods 352 are hinged to the upper plate 351.

[0039] Initially, the axis of roll 2 is parallel to the axis of drum 1. When the bidirectional drive mechanism 4 drives the two sliders 33 to approach each other along the slide bar 32, the sliders 33 generate a thrust on the long connecting rod 352 through the hinge point. The two long connecting rods 352 simultaneously transmit the symmetrical downward force to the upper plate 351. The upper plate 351 smoothly moves downward along the preset direction. One end of the upper plate 351 drives the second bearing seat 22 to move downward synchronously through the sliding connection assembly 353. Meanwhile, the first bearing seat 21 at the other end of roll 2 remains in a predetermined position with the lower plate 341, making the distance between the second bearing seat 22 and the lower plate 341 greater than the distance between the first bearing seat 21 and the upper plate 351. The axis of roll 2 changes from being parallel to the axis of drum 1 to being inclined, thus completing the adjustment of the tip angle. Through the symmetrical transmission of the long connecting rod 352 and the linkage of the upper plate 351, the adjustment of the roll 2 angle is realized without the need for an additional independent drive mechanism.

[0040] Reference Figure 7 and Figure 8 As shown: The sliding connection assembly 353 includes a first limiting sleeve 3531 and a second guide rod 3532; the first limiting sleeve 3531 is disposed on the lower plate 341; the second guide rod 3532 penetrates the first limiting sleeve 3531 vertically, and the two ends of the second guide rod 3532 are respectively connected to the second bearing seat 22 and the upper plate 351.

[0041] When the long connecting rod 352 pushes the upper plate 351 downward, the upper plate 351 drives the second guide rod 3532 to move synchronously. The first limiting sleeve 3531 forms a rigid constraint on the second guide rod 3532, limiting it to linear movement only in the vertical direction, preventing the second guide rod 3532 from deviating, swaying, or twisting. Under the guidance of the first limiting sleeve 3531, the second guide rod 3532 smoothly drives the second bearing seat 22 downward, so that the two ends of the roll 2 form a predetermined displacement difference, ensuring that the axis of the roll 2 tilts along the preset trajectory. Through the cooperation of the first limiting sleeve 3531 and the second guide rod 3532, a stable guide is provided for the movement of the second bearing seat 22, preventing deviations in the tilt angle of the roll 2.

[0042] Reference Figure 7 and Figure 8 As shown: The sliding connection assembly 353 further includes an elastic reset member 3533, which is used to provide an elastic force to the second guide rod 3532 in a direction away from the lower plate 341.

[0043] The elastic reset component 3533 is a reset spring. In the initial state, the reset spring is sleeved outside the second guide rod 3532, with its two ends abutting against the first limiting sleeve 3531 and the upper plate 351, respectively, applying an elastic force away from the lower plate 341 to the second guide rod 3532. At this time, the axis of the roll 2 remains parallel to the axis of the rotating drum 1. When the long connecting rod 352 pushes the upper plate 351 downward, the upper plate 351 drives the second guide rod 3532 to slide downward along the first limiting sleeve 3531. The upper plate 351 gradually approaches the first limiting sleeve 3531, the reset spring is compressed and stores elastic potential energy, and at the same time, it continuously applies a reverse thrust to the second guide rod 3532. After the tipping process is completed, the upper plate 351 moves upward, and the return spring releases its elastic potential energy, assisting the second guide rod 3532 to slide in the opposite direction. When the roll 2 returns to its original position parallel to the axis of the rotating drum 1, the second bearing seat 22 stops moving. The return spring maintains a certain amount of compression and stores elastic potential energy, fixing the position of the second bearing seat 22 through the continuously applied elastic force, thereby maintaining the parallel state between the axis of the roll 2 and the axis of the rotating drum 1. This prevents the roll 2 from shifting due to vibration, external interference, etc., ensuring that the axis of the roll 2 and the axis of the rotating drum 1 remain parallel at all times, providing a stable initial state for subsequent wire insertion and the next tipping process.

[0044] Reference Figure 7 and Figure 9 As shown: The second adjustment component 35 further includes a balancing component 354. The balancing component 354 and the sliding connection component 353 are respectively disposed at both ends of the upper plate 351. The balancing component 354 is used to maintain the balance of the upper plate 351.

[0045] Specifically, the balancing assembly 354 includes a second limiting sleeve 3541 and a third guide rod 3542. The second limiting sleeve 3541 is disposed on the lower plate 341, and the third guide rod 3542 penetrates the second limiting sleeve 3541 vertically, with one end of the third guide rod 3542 connected to the upper plate 351.

[0046] In the initial state, the second limiting sleeve 3541 of the balancing component 354 and the first limiting sleeve 3531 of the sliding connection component 353 are symmetrically fixed to the lower plate 341. The third guide rod 3542 vertically penetrates the second limiting sleeve 3541 and one end is connected to one end of the upper plate 351. The second guide rod 3532 penetrates the first limiting sleeve 3531 and one end is connected to the other end of the upper plate 351, keeping the upper plate 351 horizontally balanced. When the bidirectional drive mechanism 4 drives the slider 33 to approach, and the long connecting rod 352 transmits a symmetrical force to the upper plate 351, the two ends of the upper plate 351 simultaneously drive the second guide rod 3532 and the third guide rod 3542 to move. The second guide rod 3532 is constrained by the first limiting sleeve 3531, and the third guide rod 3542 is constrained by the second limiting sleeve 3541. Both slide smoothly in the vertical direction, offsetting the tilting torque that the upper plate 351 may generate, so that the upper plate 351 always moves in a horizontal state. The balancing assembly 354, consisting of the second limiting sleeve 3541 and the third guide rod 3542, forms a symmetrical guiding support structure with the sliding connection assembly 353. This effectively prevents the upper plate 351 from tilting or jamming due to uneven force during movement, ensuring the synchronous movement of both ends of the upper plate 351. Consequently, the power transmission efficiency of the roll 2 angle adjustment remains stable, and the adjustment speed will not fluctuate due to the offset of the upper plate 351, thus improving the consistency and reliability of the roll tip angle adjustment.

[0047] Reference Figure 10 As shown: A sliding sleeve 23 is provided at one end of the roller 2, and the sliding sleeve 23 is used to connect the second bearing seat 22 and the roller 2.

[0048] In the initial state, one end of the roll 2 is slidably connected to the second bearing seat 22 via the sliding sleeve 23, and the other end is fixedly connected to the first bearing seat 21. The axis of the roll 2 is parallel to the axis of the rotating drum 1. When the second adjusting component 35 drives the second bearing seat 22 to move downward, a triangular structure is formed between the roll 2, the lower plate 341, and the second bearing seat 22. Since the length of the roll 2 is fixed and greater than the initial distance between the first bearing seat 21 and the second bearing seat 22, the second bearing seat 22 needs to be displaced relative to the roll 2 to adapt to the angle change. At this time, the sliding sleeve 23 slides relative to the roll 2, which allows the second bearing seat 22 to move along the axial direction of the roll 2 without affecting the rotation function of the roll 2, ensuring that the roll 2 has no mechanical jamming during the tilt adjustment process and smoothly transitions to the set tilt angle.

[0049] Reference Figure 3 and Figure 11 As shown: The bidirectional drive mechanism 4 includes two annular transmission plates 41 and a drive assembly 42; the annular transmission plates 41 are respectively disposed at both ends of the rotating drum 1, and the annular transmission plates 41 are connected to the slider 33; the drive assembly 42 is used to drive the two annular transmission plates 41 to move towards or away from each other.

[0050] Initially, two annular transmission plates 41 are respectively mounted at both ends of the rotating drum 1 and are connected one-to-one with the sliders 33 of each linkage adjustment mechanism 3. When the steel wire needs to be tipped, the drive assembly 42 is activated and outputs driving force, driving the two annular transmission plates 41 to move towards each other along the axis of the rotating drum 1. Since the annular transmission plates 41 are connected to the sliders 33 of all linkage adjustment mechanisms 3, their opposite movement synchronously acts on multiple linkage adjustment mechanisms 3, causing each slider 33 to move closer to each other synchronously along the corresponding slide bar 32, thereby activating the first adjustment assembly 34 and the second adjustment assembly 35. Through the overall linkage design of the annular transmission plates 41, the synchronous adjustment of all rolls 2 is achieved, ensuring that all rolls 2 move the same distance and tilt at the same angle along the axis of the rotating drum 1, avoiding the problem of asynchronous movement of rolls 2 caused by individual adjustment.

[0051] Reference Figure 11 As shown: There are at least two drive components 42, and the two drive components 42 are arranged around the axis of the rotating drum 1 outside the rotating drum 1.

[0052] In the initial state, at least two drive components 42 are evenly distributed around the axis of the rotating drum 1 on its exterior, and are all connected to the annular transmission plate 41, ensuring that the driving force is evenly distributed circumferentially along the annular transmission plate 41. When it is necessary to drive the annular transmission plate 41 to move, all drive components 42 start synchronously, applying a driving force along the axis of the rotating drum 1 to the annular transmission plate 41. Because the drive components 42 are evenly arranged circumferentially, the tilting of the annular transmission plate 41 caused by unilateral force is avoided, allowing the annular transmission plate 41 to move smoothly towards or away from each other along the axis, synchronously transmitting the force to the sliders 33 of all linkage adjustment mechanisms 3, ensuring that each slider 33 starts and moves synchronously. By evenly arranging multiple drive components 42 around the axis of the rotating drum 1, the annular transmission plate 41 is subjected to balanced force and moves smoothly, avoiding action delay caused by unilateral drive.

[0053] Reference Figure 11 and Figure 12 As shown: The drive assembly 42 includes a rolling assembly 421, which abuts against the annular transmission plate 41 to reduce the friction between the drive assembly 42 and the annular transmission plate 41.

[0054] Specifically, the drive assembly 42 also includes a mounting plate 422 and two linear actuators 423. The mounting plate 422 is disposed on one side of the rotating drum 1, and the two linear actuators 423 are respectively disposed at both ends of the mounting plate 422. The rolling assembly 421 is disposed at the output end of the linear actuators 423.

[0055] During the adjustment of the roller 2, the drum 1 rotates, causing the two annular transmission plates 41 to rotate synchronously. Sliding friction occurs between the drive assembly 42 and the annular transmission plates 41. Therefore, a rolling assembly 421 is provided. When the drum 1 rotates, causing the two annular transmission plates 41 to rotate synchronously, and the linear actuator 423 starts simultaneously, the driving force along the axis of the drum 1 is transmitted to the annular transmission plates 41 through the rolling assembly 421 at the output end of the linear actuator 423. During the rotation of the annular transmission plates 41, rolling friction is formed between them and the rolling assembly 421, replacing sliding friction. This ensures stable transmission of driving force and avoids wear caused by relative sliding, significantly reducing relative motion resistance and wear, and extending the service life of components.

[0056] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
