Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel wire winding, in particular to a constant tension control winding device and its application in steel wire rough drawing. BACKGROUND

[0002] The rough drawing treatment (also known as rough drawing or primary drawing) of steel wire is a key process in steel wire processing, aiming to reduce the diameter of hot-rolled wire rod or larger diameter steel wire through drawing, to provide semi-finished products for subsequent fine drawing.

[0003] Winding the steel wire after rough drawing is a key step to ensure product quality, facilitate storage and subsequent processing. The winding process needs to control tension, arrangement and winding stability, and the fluctuation of tension is one of the important reasons affecting the winding quality.

[0004] The main reason for tension fluctuation is the difference between the release speed and the winding speed of the steel wire. If the release speed is greater than the winding speed, the steel wire is in a relaxed state, which will cause the steel wire to be loose and collapsed. If the release rate is less than the winding speed, the steel wire is in a tense state, which will cause the steel wire to wear and even break.

[0005] In the prior art, the rotational speed of the winding roller and the release roller of the steel wire is usually controlled to match each other to ensure stable winding of the steel wire. However, as the winding thickness of the winding roller increases, the winding speed of the winding roller is in a state of continuous increase, which causes the steel wire to be tense, and further causes the surface of the steel wire to be scratched or the winding process to be interrupted.

[0006] To this end, the rotational speed of the winding roller can be dynamically adjusted according to the winding turns of the steel wire to compensate for the influence of the change in winding diameter, so as to balance the tension. However, in actual operation, the steel wire needs to be guided by a threader to arrange regularly during the winding process. The threader moves back and forth along the axial direction of the winding roller, which will inevitably cause the length of the steel wire path to change. The steel wire will be in a state of continuous change between relaxation and tension, and further cause the tension to fluctuate obviously, resulting in uneven winding tension. SUMMARY

[0007] The present application aims to provide a constant tension control winding device and its application in steel wire rough drawing to solve the problems raised in the background art.

[0008] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0013] A tension balance mechanism is arranged on the fixed plate and connected with the wire arrangement component, and the tension balance mechanism comprises a supporting roller, and the tension balance mechanism can drive the supporting roller to move in the vertical direction when the wire arrangement component moves;

[0014] A winding component is arranged on the lifting plate, and the winding component comprises symmetrically arranged winding rollers, and a follow-up limiting mechanism is further arranged on the lifting plate, and the follow-up limiting mechanism can perform limiting or releasing actions on the winding rollers when the winding rollers move.

[0015] As a further scheme of the present application, the wire arrangement component comprises a lead screw rotatably arranged on the lifting plate, and a threaded sleeve is threadedly connected to the lead screw;

[0016] A guide column fixed to the lifting plate is further included, and a guide sleeve is axially slidably arranged on the guide column, and a connecting plate fixedly connected with the threaded sleeve is fixed to the side wall of the guide sleeve.

[0017] As a further scheme of the present application, the tension balance mechanism comprises a supporting sleeve fixed to the fixed plate, and a supporting rod is axially slidably arranged in the supporting sleeve, and the supporting rod is fixedly connected with the supporting roller;

[0018] A driven component and an elastic component for adjusting the height of the supporting roller are further arranged on the supporting sleeve and connected with the threaded sleeve.

[0019] As a further scheme of the present application, the driven component comprises a rotating ring axially slidably arranged along the supporting sleeve and rotatably arranged along the circumference of the supporting sleeve, a yawing rod is rotatably arranged on the side wall of the threaded sleeve, and a connecting rod hingedly connected with the rotating ring is hingedly arranged on the yawing rod.

[0020] As a further scheme of the present application, the elastic component comprises a through groove formed in the circumferential outer wall of the supporting sleeve, a movable ring slidably connected with the through groove is fixed to the supporting rod, and a first spring is sleeved on the supporting sleeve, and the two ends of the first spring are respectively in abutment with the movable ring and the rotating ring.

[0021] As a further scheme of the present application, the winding component comprises a rotating rod rotatably arranged on the lifting plate, a rotating plate is fixed to the rotating rod, symmetrically arranged motors are fixed to the rotating plate, a transmission rod connected with the output shaft of the motor is rotatably arranged on the rotating plate, and the transmission rod is slidably connected with the winding rollers.

[0022] As a further further scheme of the present application: the follow-up limiting mechanism comprises a fixing disc fixed on the lifting plate, a guide rail is formed on the inner wall of the fixing disc, and a supporting plate is slidably installed in the guide rail;

[0023] Further comprising a locking assembly arranged on the supporting plate and used for providing a locking force to the winding roller.

[0024] As a further further scheme of the present application: the locking assembly comprises movable rods slidably installed on the supporting plate and symmetrically arranged, and a matching block slidably connected with the winding roller is fixed on the end of the movable rod.

[0025] As a further further scheme of the present application: the locking assembly further comprises a guide groove opened in the inner wall of the fixing disc, a follow-up ring is fixed on the movable rod, a limiting column slidably matched with the guide groove is fixed on the follow-up ring, a second spring is axially sleeved on the movable rod, and the two ends of the second spring are respectively abutted with the follow-up ring and the supporting plate.

[0026] A constant tension control winding device is applied to steel wire rough drawing.

[0027] Compared with the prior art, the present application has the beneficial effects that: during the winding and arranging process of the steel wire, the supporting force to the steel wire is continuously adjusted according to the change of the arranging position, so that the tension of the steel wire is always kept within a constant range. Specifically, when the steel wire passes through the arranging assembly and is fixed on the winding roller, the follow-up limiting mechanism can ensure that the winding roller does not deviate when winding the steel wire, so as to ensure the stability of winding. Meanwhile, through the cooperation of the arranging assembly and the winding, the steel wire can be guided to be regularly wound on the winding roller, so that the steel wires will not be staggered and overlapped due to irregular winding, and the problem of mutual friction between the steel wires is solved. When the arranging assembly moves, the tension balancing mechanism also moves, so that the supporting force of the supporting roller to the steel wire can be adjusted in real time according to the change of the pulling amount of the steel wire, and the tension of the steel wire is kept constant.

[0028] Through the cooperation of the winding assembly and the follow-up limiting mechanism, the positions of the two winding rollers can be switched, so that when the winding amount of one winding roller reaches a set value, the other winding roller can be quickly controlled to move to the required winding position. During the position switching process, the locking state of the winding roller is adjusted, so that the winding roller with the steel wire wound thereon is not locked, so as to facilitate disassembly and replacement, and the winding roller without the steel wire wound thereon is in a locked state, so as to ensure that the winding roller does not move during winding. In this way, the winding roller does not need to be replaced at the winding position, and the winding efficiency of the steel wire is improved.

[0029] Through synchronous control of the horizontal movement of the wire ring and the vertical movement of the supporting roller, auxiliary wire winding during wire winding and straightening can be realized, so as to ensure that the wire winding is not loose due to tension fluctuation, and the wire is not broken due to being too tight, and the timeliness of tension adjustment is ensured, and the problem of unstable tension caused by delayed adjustment is prevented.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0047] Please refer to Figures 1-14 In the embodiments of the present application, a constant tension control winding device comprises:

[0048] Support 1, lifting plate 2 and fixed plate 3 fixed on support 1;

[0049] Further comprising:

[0050] Wire arrangement assembly provided on the lifting plate 2, the wire arrangement assembly is connected with the wire ring 26 for guiding the winding of steel wire;

[0051] A tension balance mechanism is arranged on the fixing plate 3 and connected with the wire arranging assembly, and the tension balance mechanism comprises a supporting roller 8, and the tension balance mechanism can drive the supporting roller 8 to move in the vertical direction when the wire arranging assembly moves;

[0052] A winding assembly is arranged on the lifting plate 2, and the winding assembly comprises symmetrically arranged winding rollers 13, and a follow-up limiting mechanism is further arranged on the lifting plate 2, and the follow-up limiting mechanism can perform a limiting or releasing action on the winding rollers 13 when the winding rollers 13 move.

[0053] Specifically, when the steel wire is wound after rough drawing, the end of the steel wire is fixed on the winding roller 13, the wire arranging assembly guides the winding track of the steel wire, the tension balance mechanism provides a certain tension to the steel wire through the supporting roller 8, and the follow-up limiting mechanism can ensure that one of the winding rollers 13 for winding the steel wire is in a position-locked state, the winding assembly drives the winding roller 13 to rotate at a rotating speed matching the unwinding speed to wind the steel wire, and the wire arranging assembly guides the steel wire to be regularly wound on the winding roller 13 to prevent the problem of scratches between the steel wires caused by the interlaced winding and stacking of the steel wires. During the wire arranging process of the wire arranging assembly, the pulling angle of the steel wire in the horizontal direction changes, which causes the tension provided by the winding roller 13 to the steel wire to fluctuate. To this end, the wire arranging assembly drives the tension balance mechanism to move, so that the tension provided by the winding roller 13 to the steel wire is always kept within a certain range, thereby avoiding the problems of “collapsed winding” caused by the interlayer sliding of the loose winding due to the fluctuation of the tension being too large or too small, and the friction or rupture of the steel wire caused by the excessive force of the steel wire. When the winding amount of the winding roller 13 reaches a certain value, the winding roller 13 needs to be switched. Under the action of the winding assembly, the positions of the two winding rollers 13 are adjusted to each other, and under the action of the follow-up limiting mechanism, the winding roller 13 wound with the steel wire is no longer locked, so as to facilitate the removal of the winding roller 13 and the insertion of a new winding roller 13, and the winding roller 13 not wound with the steel wire is locked to ensure that the winding roller 13 does not shake during the winding process.

[0054] Please refer to Figures 1-3 , Figure 7 , Figure 8 , Figure 12 The winding assembly comprises a rotating rod 9 rotatably arranged on the lifting plate 2, a rotating plate 10 fixed on the rotating rod 9, symmetrically arranged motors 11 fixed on the rotating plate 10, a transmission rod 12 rotatably arranged on the rotating plate 10 and connected with output shafts of the motors 11, and the transmission rod 12 is in sliding connection with the winding rollers 13.

[0055] Please refer to Figures 1-3 , Figures 7-13 The follow-up limiting mechanism comprises a fixed disc 14 fixed on the lifting plate 2, a guide rail 1401 is formed on the inner wall of the circumference of the fixed disc 14, and a supporting plate 15 is slidably installed in the guide rail 1401; the locking assembly provided on the supporting plate 15 is used to provide locking force for the winding roller 13, the locking assembly comprises a movable rod 16 symmetrically installed on the supporting plate 15, the end of the movable rod 16 is fixed with a fitting block 17 in sliding connection with the winding roller 13, the locking assembly further comprises a guide groove opened on the inner wall of the circumference of the fixed disc 14, a follow-up ring 18 is fixed on the movable rod 16, a limiting column 19 in sliding fit with the guide groove is fixed on the follow-up ring 18, and a second spring 20 is axially sleeved on the movable rod 16, and the two ends of the second spring 20 are respectively in abutment with the follow-up ring 18 and the supporting plate 15.

[0056] Please refer to Figures 1-4 The wire arrangement assembly comprises a lead screw 21 rotatably installed on the lifting plate 2, and a threaded sleeve 22 is threadedly connected on the lead screw 21; the wire arrangement assembly further comprises a guide column 24 fixed on the lifting plate 2, and a guide sleeve 25 is slidably arranged on the guide column 24 in the axial direction, and a connecting plate 23 fixedly connected with the threaded sleeve 22 is fixed on the side wall of the guide sleeve 25.

[0057] In detail, the rotating rod 9 is fixedly connected with the supporting plate 15, the winding roller 13 is provided with two, and when the winding amount of one of the winding rollers 13 reaches a set value, the positions of the two winding rollers 13 are quickly switched to ensure that the winding efficiency is in a high state, a key groove is formed on the inner wall of the rotating shaft of the winding roller 13, and a key is fixedly connected on the outer circumference of the transmission rod 12 and is in fit with the key groove, when the winding roller 13 is inserted into the transmission rod 12, under the action of the key and the key groove, the transmission rod 12 can drive the winding roller 13 to rotate;

[0058] Please refer to Figure 9 , Figure 10The guide groove can be divided into three sections, which are annular groove 1402, first inclined groove 1403 and second inclined groove 1404, and the annular groove 1402, the first inclined groove 1403 and the second inclined groove 1404 are sequentially connected to each other, and the two sides of the rotating rod 9 as the center axis can be divided into a winding side and a release side, the winding roller 13 for winding the steel wire is located on the winding side, and the winding roller 13 for replacement is located on the release side. In the initial state, one of the limiting columns 19 on the winding side is in the annular groove 1402, so that the distance between the follow-up ring 18 connected thereto and the support plate 15 is maximum, so that the embedded block 17 is inserted into the winding roller 13 by the movable rod 16, and the winding roller 13 is locked in the axial position of the transmission rod 12. The other limiting column 19 on the release side is located at the connection position of the first inclined groove 1403 and the second inclined groove 1404, so that the embedded block 17 is separated from the winding roller 13 by the movable rod 16, the winding roller 13 can be freely separated from the transmission rod 12, and the action of replacing the winding roller 13 can be performed;

[0059] Taking the winding roller 13 on the winding side as an example, when the steel wire needs to be wound, in the initial state, under the action of the lead screw 21, the threaded sleeve 22 is located at the end of the stroke on one side of the winding roller 13, and the guide sleeve 25 is also located on one side of the winding roller 13 by the connecting plate 23. At this time, the steel wire can pass through the wire ring 26, and the end of the steel wire is fixed on the winding roller 13;

[0060] At this time, the motor 11 on the winding side works, and drives the winding roller 13 to rotate through the transmission rod 12, so as to wind the steel wire. At the same time, the lead screw 21 rotates and drives the threaded sleeve 22 to move, so as to control the guide sleeve 25 to move along the length direction of the guide column 24 through the connecting plate 23. The guide sleeve 25 and the guide column 24 have a guiding effect, which can ensure that the threaded sleeve 22 does not rotate with the lead screw 21 during movement. The guide sleeve 25 also drives the wire ring 26 to slide along the axial direction of the winding roller 13, so as to guide the winding track of the steel wire, and ensure that the steel wire is regularly wound on the winding roller 13. When the steel wire is tightly and regularly wound on the winding roller 13, at this time, the lead screw 21 is reversed, and the wire ring 26 is controlled to move towards the initial position, so as to control the steel wire to be regularly wound on the next layer. Repeat the above steps until the winding amount of the steel wire reaches the set value.

[0061] Wherein, in the winding process, since the unwinding rate is always kept constant, as the steel wire winding thickness gradually increases, the winding amount of a winding of the steel wire will also increase, in order to ensure that the tension received by the steel wire is always within a constant range, it is necessary to reduce the rotating speed of the winding roller 13, for this, whenever the steel wire winds a layer, the motor 11 will reduce the rotating speed of the transmission rod 12 by a certain amount, so as to prevent the steel wire winding speed from increasing as the winding thickness increases, and gradually increase the tension received by the steel wire, causing the steel wire to have excessive friction or breakage. The change in the rotating speed of the transmission rod 12 controlled by the motor 11 is set according to the circumferential diameter of the steel wire, which is an application of the prior art, and will not be described herein.

[0062] Subsequently, the motor 11 stops working, under the action of the rotating rod 9, the rotating plate 10 is driven to move, thereby moving the winding roller 13 on which the steel wire is wound to the release side, the rotating rod 9 also drives the support plate 15 to slide along the guide rail 1401, under the action of the support plate 15, the limiting column 19 located on the winding side is controlled to slide along the annular groove 1402, when the limiting column 19 is separated from the annular groove 1402 and enters the first inclined groove 1403, thereby controlling the fitting block 17 to separate from the winding roller 13 through the follow-up ring 18 and the movable rod 16, when the limiting column 19 moves to the connecting position of the first inclined groove 1403 and the second inclined groove 1404, the distance between the fitting block 17 and the winding roller 13 reaches the maximum, the positions of the two winding rollers 13 are interchanged, and the winding roller 13 on which the steel wire is wound is no longer locked, at this time, the winding roller 13 can be taken away and a new winding roller 13 can be replaced;

[0063] At the same time, the limiting column 19 located on the release side will enter the second inclined groove 1404 to control the fitting block 17 to move towards the winding roller 13 which does not wind the steel wire, when the limiting column 19 is separated from the second inclined groove 1404 and enters the annular groove 1402, it means that the fitting block 17 is completely inserted into the winding roller 13 and locks the position of the winding roller 13, when the winding roller 13 moves to the required winding position on the winding side, the cooperating motor 11 works and drives the winding roller 13 to wind the steel wire again through the transmission rod 12, the above steps are repeated to realize the continuous winding of the steel wire, wherein the rotation of the rotating rod 9 and the screw rod 21 can be driven by a motor (not shown in the figure) or other driving sources, which is an application of the prior art and will not be described herein.

[0064] Preferably, by switching the position of the two winding rollers 13, the other winding roller 13 can be quickly controlled to move to the required winding position when the winding amount of one winding roller 13 reaches the set value, and during the position switching process, the locking state of the winding roller 13 is adjusted to ensure that the winding roller 13 with steel wire is not locked to facilitate disassembly and replacement, and the winding roller 13 without steel wire is in the locked state to ensure that the winding roller 13 does not displace during winding. In this way, the winding roller 13 does not need to be replaced at the winding position, and the winding efficiency of the steel wire is improved.

[0065] Please refer to Figures 1-6 The tension balance mechanism includes a support sleeve 4 fixed on the fixed plate 3, a support rod 5 axially sliding in the support sleeve 4, and the support rod 5 being fixedly connected with the support roller 8. Further, a driven assembly and an elastic assembly for adjusting the height of the support roller 8 are arranged on the support sleeve 4 and connected with the threaded sleeve 22. The driven assembly includes a rotating ring 6 axially sliding along the support sleeve 4 and being able to rotate circumferentially along the support sleeve 4. A yawing rod 27 is rotatably mounted on the sidewall of the threaded sleeve 22, and the yawing rod 27 is hingedly connected with a connecting rod 28 hingedly connected with the rotating ring 6. The elastic assembly includes a through slot 401 opened in the circumferential outer wall of the support sleeve 4, and an active ring 501 fixed on the support rod 5 is slidingly connected with the through slot 401. A first spring 7 is sleeved on the support sleeve 4, and the two ends of the first spring 7 are respectively abutted with the active ring 501 and the rotating ring 6.

[0066] Further, when winding the steel wire, the steel wire can pass through the support roller 8 and the wire guide ring 26, and under the action of the support roller 8, the steel wire maintains a certain tension;

[0067] In order to ensure that the steel wire is regularly wound on the winding roller 13, the wire guide ring 26 needs to reciprocate along the axial direction of the winding roller 13. During the movement of the wire guide ring 26, the included angle and the spacing between the wire guide ring 26 and the support roller 8 will change due to the change of the traction position. In this regard, if the elastic support force provided by the support roller 8 to the steel wire remains unchanged, when the wire guide ring 26 moves to the positions on both sides of the winding roller 13, the spacing between the wire guide ring 26 and the support roller 8 reaches the maximum, and the pulling force on the steel wire will increase, resulting in an increase in the tension of the steel wire. When the wire guide ring 26 moves to the middle position of the winding roller 13, the spacing between the wire guide ring 26 and the winding roller 13 is the smallest, and the pulling force on the steel wire decreases, resulting in a decrease in the tension of the steel wire.

[0068] Therefore, the elastic support force of the support roller 8 needs to be adjusted in real time according to the position of the wire guide ring 26 to prevent the tension from fluctuating too much, resulting in problems such as looseness or tightness during winding;

[0069] Please refer to Figure 4 With the initial state that the wire ring 26 is located in the middle position of the winding roller 13, the distance between the threaded sleeve 22 and the support sleeve 4 is the smallest, so that the pulling force of the wire ring 26 on the steel wire is the smallest, and the steel wire is in a relaxed state without support force. Under the action of the deflection rod 27 and the connecting rod 28, the control rotating ring 6 is located at the end of the stroke towards the fixed plate 3, so that the movable ring 501 is controlled by the first spring 7 to be located at the end of the stroke towards the fixed plate 3. The movable ring 501 will control the minimum distance between the support roller 8 and the fixed plate 3 through the support rod 5. The support roller 8 will compensate the relaxed part of the steel wire, so as to ensure that the steel wire is in a taut state and the tension is within the required setting range.

[0070] When it is necessary to wind the steel wire, the wire ring 26 will move towards one side of the winding roller 13, and the pulling force on the steel wire will increase, so that the steel wire is in a continuously taut state. Under the action of the threaded sleeve 22, the control rotating ring 6 is controlled to rotate around the support sleeve 4 in the circumferential direction through the deflection rod 27 and the connecting rod 28, and the deflection rod 27 will also rotate itself to ensure that the connecting rod 28, the deflection rod 27 and the control rotating ring 6 are always in the same vertical reference plane. At the same time, the control rotating ring 6 will also slide along the axial direction of the support sleeve 4 and move away from the fixed plate 3, so that the elasticity of the first spring 7 is released, thereby reducing the support force of the support roller 8 on the steel wire, so as to keep the steel wire within a certain tension range.

[0071] When the wire ring 26 moves to the edge position of the winding roller 13, the pulling force on the steel wire is the largest, and under the action of the connecting rod 28, the distance between the support roller 8 and the fixed plate 3 is the largest, so as to reduce the support force on the steel wire, and ensure that the tension of the steel wire is within a constant range. When the wire ring 26 moves towards the other side of the winding roller 13, the pulling force on the steel wire decreases, and under the action of the connecting rod 28, the control rotating ring 6 moves towards the fixed plate 3, so as to compensate the steel wire in a relaxed state through the support roller 8, and repeat the above steps, so as to effectively overcome the problem that the tension of the steel wire fluctuates due to the continuous change of the winding position during the winding process of the steel wire, the different pulling amount of the steel wire, and the continuous change of the steel wire in a relaxed and taut state.

[0072] Preferably, by synchronously controlling the horizontal movement of the wire ring 26 and the vertical movement of the support roller 8, the steel wire can be kept within a certain tension range during the winding process, which can not only assist the winding of the steel wire, ensure that the steel wire will not be loose during winding due to tension fluctuation, cause the problem of collapse, or be too taut to cause the problem of steel wire breakage, but also ensure the timeliness of tension adjustment, prevent the problem of unstable tension due to delayed adjustment.

[0073] The application relates to an application of a constant tension control winding device in steel wire rough drawing.
