TECHNICAL FIELD
[0001] The present application relates to the technical field of metal wire straightening, and particularly relates to an alloy wire conveying and straightening device. BACKGROUND
[0002] Alloy wires are usually stored and transported in the form of large coils. During winding and unloading, the wires will inevitably be bent and deformed. In addition, some alloy wires have uneven residual stress after plastic processing such as drawing and rolling, which causes the alloy wires to be unable to maintain straightness and to naturally bend. Therefore, the alloy wires need to be straightened before use to avoid the influence of the bending or internal stress of the alloy wires on the finished product.
[0003] At present, the straightening of the alloy wires is achieved by cooperation of multiple groups of pressing rollers. The alloy wires pass between the pressing rollers in the same group, which not only straightens the alloy wires but also provides traction for the conveying of the alloy wires. The straightening of the alloy wires is achieved by extruding the surface of the wire in multiple directions and simultaneously conveying the wire, so as to straighten the alloy wires. The conveying resistance generated by the extrusion of the alloy wires is likely to cause the wire to be extended to some extent, which changes the thickness specification of the wire. In addition, the traction for conveying is only provided by the rotation and friction of the pressing rollers, and the conveying of the alloy wires is likely to be intermittent and stagnant, which greatly affects the conveying and fixed-distance cutting of the alloy wires and is likely to cause the length tolerance of the cut alloy wires to be unsatisfactory. SUMMARY
[0004] The present application provides an alloy wire conveying and straightening device to solve the defects that the alloy wires are extruded to cause the conveying resistance to be too large and change the thickness specification of the wire, and the conveying and fixed-distance cutting of the alloy wires are greatly affected and are likely to cause the length tolerance of the cut alloy wires to be unsatisfactory.
[0005] The present application provides an alloy wire conveying and straightening device, which comprises: The extrusion and conveying part comprises a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is arranged before the alloy wire enters the straightening part and is configured to convey the alloy wire initially. The second conveying mechanism is arranged after the alloy wire exits the straightening part and is configured to convey the straightened alloy wire. The straightening part comprises a rotating frame with rotating shafts arranged along the conveying direction of the alloy wire. At least two sides of the rotating frame are fixedly connected with a plurality of straightening rollers arranged in a staggered manner. The surface of the straightening roller is configured to abut against the alloy wire to straighten the alloy wire. The rotating shaft of the straightening roller is inclined to intersect with the alloy wire. The dragging and cutting assembly comprises a dragging slider before the alloy wire is conveyed to the extrusion and conveying part. A bushing is arranged in the dragging slider. A clamping piece is arranged in the bushing. The dragging slider is moved away from the straightening part to clamp the alloy wire by the clamping piece. A cutting assembly is arranged on the side of the dragging slider away from the second conveying mechanism.
[0006] In a further embodiment, the first conveying mechanism is configured to convey the alloy wire in a primary straightening manner, the second conveying mechanism is configured to convey the alloy wire in a secondary straightening manner, the rotating frame is located between the first conveying mechanism and the second conveying mechanism, the rotating frame has rotating shafts distributed along the conveying direction of the alloy wire, the rotating shafts of the straightening rollers on the two sides are perpendicular to each other, and the rotating shafts of the straightening rollers and the conveying direction of the alloy wire form an angle of 45°.
[0007] In a further embodiment, the rotating frame is located in the middle of the base, the first conveying mechanism and the second conveying mechanism each include a mounting table fixedly connected to the surface of the base, one side of the mounting table is rotatably connected with a plurality of uniformly distributed extrusion rollers, and the extrusion rollers on the upper and lower sides of the same extrusion roller group are matched with each other.
[0008] In a further embodiment, the other side of the mounting table connected with the extrusion rollers is provided with a plurality of uniformly distributed linkage gears, the rotating shafts of the linkage gears and the extrusion rollers are fixedly connected, and the linkage gears on the extrusion rollers in the same extrusion roller group are meshed with each other.
[0009] In a further embodiment, the pulling and cutting assembly further includes a mounting sleeve fixedly connected to the surface of the base away from the first conveying mechanism, the pulling slider is located in the mounting sleeve, and a rotating wheel is rotatably connected to the side of the mounting sleeve close to the pulling slider.
[0010] In a further embodiment, a plurality of mounting holes are formed in the surface of the side of the rotating wheel close to the pulling slider, the distances from the mounting holes to the center of the rotating wheel are different, a connecting driving block is detachably arranged in any mounting hole, a driving rod is fixedly connected to the top of the pulling slider, and a limiting piece is arranged between the driving rod and the mounting sleeve.
[0011] In a further embodiment, the driving rod reciprocates inside the mounting sleeve along the conveying direction of the alloy wire, the connecting driving block is sleeved on the driving rod, the connecting driving block reciprocates along the driving rod under the driving of the rotating wheel, and the connecting driving block is arranged in different mounting holes to adjust the reciprocating distance of the driving rod.
[0012] In a further embodiment, the width of the pulling slider inside gradually decreases along the direction close to the second conveying mechanism, a sleeve is fixedly connected to each end of the outside of the bushing along the conveying direction of the alloy wire, the sleeves extend to the outside of the pulling slider, and an extrusion piece is sleeved on the sleeve away from the second conveying mechanism on the outside of the bushing.

The moving speed of the drag slider is the same as the conveying speed of the extrusion conveying section on the alloy wire.
[0014] The alloy wire conveying and straightening device provided by this invention has the following technical effects or advantages: The rotation of the rotating frame, which is distributed along the conveying direction of the alloy wire, causes the straightening rollers inside to be arranged in an alternating manner to extrude the alloy wire. The rotating shaft of the straightening roller is inclined to intersect with the conveying direction of the alloy wire, which is different from the tangential point contact. This prolongs the extrusion contact time between the straightening roller and the alloy wire and avoids affecting the thickness of the alloy wire itself during the straightening process.
[0015] By dragging the slider in a reciprocating motion, as the slider moves along the alloy wire conveying direction, it works in conjunction with the internal bushings to compress the clamping components, which then hold the alloy wire in place. This provides conveying assistance and reduces the possibility of slippage affecting the accuracy of the alloy wire cutting length during conveying. When the slider moves in the opposite direction of the alloy wire conveying direction, the clamping components move away from each other to avoid obstructing the conveying of the alloy wire.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0020] As mentioned above, the existing technology only provides traction and conveying through the rotational friction of the pressure roller. In order to reduce wear, the surface of the metal wire is coated with lubricating oil, which makes the conveying of the metal wire prone to intermittent stagnation. This has a significant impact on the conveying and fixed-distance cutting of the metal wire, and easily causes the length tolerance of the metal wire to be unsatisfactory.
[0021] To address this issue, the present invention provides an alloy wire conveying and straightening device. The device utilizes a dragging slider 301 in a reciprocating motion. When the dragging slider 301 moves along the wire conveying direction, it cooperates with the internal bushing 302 to compress the clamping member 303, which then securely holds the metal wire. This provides conveying assistance and reduces the impact of slippage on the accuracy of the wire cutting length during conveying. When the dragging slider 301 moves in the opposite direction of the wire conveying direction, the clamping members 303 move away from each other to avoid obstructing the wire conveying.
[0022] With the mounting holes 306 on the surface of the rotating wheel 305 at different distances from its center, the connecting drive block 307 can be detachably installed in different mounting holes 306, so that the position of the connecting drive block 307 in the mounting hole 306 can be adjusted according to the different lengths of the metal wires to be cut.
[0023] The straightening section 2 employs a rotating frame 201 with straightening rollers 202 inclined at different directions inside to perform contact-type compression straightening of the metal wire during the conveying process. The straightening rollers 202 are inclined and can rotate during the metal wire conveying process, unlike clamping straightening, thus reducing scratches on the surface of the metal wire. This wire conveying and straightening device can be used for straightening, conveying, and slitting of materials including magnesium wire, copper wire, titanium wire, and iron wire.
[0024] The following is combined Figures 1 to 11 This invention is described in detail.
[0025] First embodiment: like Figures 1 to 5 As shown, the present invention provides a wire conveying and straightening device, particularly an alloy wire conveying and straightening device. In this embodiment, the conveying and straightening device mainly includes a compression conveying section 1, a straightening section 2, a dragging and slitting assembly 3, a slitting component 4, and a base 5. Figure 1 As shown, the base 5 serves as the mounting foundation for the conveying and straightening device. A straightening section 2 is positioned in the middle of the upper surface of the base 5. The straightening section 2 includes a rotating frame 201, with two ends of the rotating frame 201 and two points in the middle of the base 5, as shown in the figure. Figure 2 The two protrusions shown are rotatably connected on their sides, and the metal wire to be straightened passes through the rotating frame 201 along its axis of rotation. Turntables are provided at both ends of the rotating frame 201 on the sides where the two protrusions are furthest apart, as shown in the example. Figure 2 A turntable, as shown, is connected to a motor drive wheel at the bottom of the base 5 via a belt or other transmission component. The motor inside the base 5 drives the rotating frame 201. This is to straighten the metal wire fed into the rotating frame 201 through rotation. [The text then abruptly shifts to a description of the rotating frame 201, mentioning internal components on both sides.] Figure 3As shown, several evenly distributed straightening rollers 202 are provided, with the straightening rollers on both sides staggered from each other. For example, the gaps between the straightening rollers 202 on one side and the straightening rollers 202 on the other side are aligned. Figure 3 As shown, the rotation axes of the straightening rollers 202 on both sides are at a 45° angle to the rotation axis of the rotating frame 201. This allows the rollers to rotate when the rotating frame 201 rotates, reducing scratches on the surface of the metal wire and reducing damage to the surface of the metal wire. It also appropriately extends the contact length between the straightening rollers 202 and the metal wire.
[0026] like Figure 3 As shown, the straightening rollers 202 on both sides of the rotating frame 201 have their rotation axes aligned normally. The straightening rollers 202 on both sides are tilted in opposite directions. The staggered distribution of the straightening rollers 202 on both sides extends the straightening length of the metal wire. Two extrusion conveying sections 1 are provided on the surface of the base 5. The extrusion conveying section 1 is used for conveying and extruding the metal wire. The extrusion conveying section 1 includes a first conveying mechanism 101 and a second conveying mechanism 102. The first conveying mechanism 101 and the second conveying mechanism 102 include mounting platforms 6 and extrusion rollers 7. The mounting platforms 6 of the first conveying mechanism 101 and the second conveying mechanism 102 are located on both sides of the base 5. The first conveying mechanism 101 is used for initial extrusion and conveying of the metal wire, and the second conveying mechanism 102 is used for further extrusion and conveying of the straightened metal wire.
[0027] To reduce the impact of slippage during the conveying of metal wire by the extrusion conveyor 1 on the conveying of the metal wire and the subsequent cutting length, a drag-and-cut assembly 3 is also provided on the surface of the base 5 on the side of the second conveying mechanism 102 away from the straightening section 2. The drag-and-cut assembly 3 includes a mounting housing 304 fixedly connected to the surface of the base 5. A rotating wheel 305 is provided inside the mounting housing 304. A connecting drive block 307 is provided on the side of the rotating wheel 305 away from the mounting housing 304. The connecting drive block 307 and the rotating wheel 305 are rotatably connected together, forming a crank through the combination of the rotating wheel 305 and the connecting drive block 307. A drive rod 308 is provided on the side of the rotating wheel 305 away from the mounting housing 304. The connecting drive block 307 is fitted onto the drive rod 308. To ensure that the formed crank can only drive the drive rod 308 to reciprocate along the conveying direction of the metal wire, a limiting member 9 is provided between the top of the drive rod 308 and the mounting housing 304. Figure 4As shown, the limiting member 9 can be two guide rods. The two ends of the guide rods are fixedly connected to both sides inside the mounting housing 304, and the guide rods pass through the drive rod 308. During the rotation of the rotating wheel 305, the connecting drive block 307 rotates with the rotating wheel 305, and its vertical displacement is offset by the reciprocating motion of the connecting drive block 307 on the drive rod 308. The connecting drive block 307 drives the drive rod 308 to reciprocate along the direction of metal wire conveying.
[0028] To achieve continuous and fixed-distance dragging of the metal wire, a dragging slider 301 is fixedly connected to the bottom end of the drive rod 308. A bushing 302 is also provided inside the dragging slider 301. The metal wire passes through the center of the bushing 302, and the interior of the dragging slider 301 is as follows: Figure 9 As shown, the internal width of the bushing 302 decreases as it gets closer to the second conveying mechanism 102. That is, once the bushing 302 moves closer to the second conveying mechanism 102 relative to the drag slider 301, the distance between the inner wall of the drag slider 301 and the bushing 302 decreases. Clamping members 303 are provided on both sides of the metal wire inside the bushing 302. Grooves are provided on the sides of the clamping members 303 that are close to each other, using the formed texture to achieve a non-slip function for clamping the metal wire. The distance between the clamping members 303 can increase or decrease with the relative movement between the bushing 302 and the drag slider 301. When the bushing 302 moves closer to the second conveying mechanism 102 relative to the drag slider 301, the clamping members 303 will move closer together to clamp the metal wire.
[0029] Therefore, when the drive rod 308 moves the drag slider 301 away from the second conveying mechanism 102, the clamping member 303 can clamp the metal wire, allowing the metal wire to move together with the drive rod 308. Adjustments need to be made based on the rotational speed of the rotary wheel 305 and the conveying speed of the extrusion conveying section 1 to ensure consistent conveying speeds between the two. To ensure timely clamping and fixing of the metal wire by the clamping member 303, sleeves 10 are fixedly connected to both ends of the bushing 302. The other ends of the sleeves 10 extending from the drag slider 301 extend from the bushing 302. An extrusion member 11 is fitted onto one sleeve 10 away from the second conveying mechanism 102. The extrusion member 11 includes a spring, which is located between the bushing 302 and the drag slider 301, pressing the bushing 302 towards the second conveying mechanism 102. Connecting slide rails 12 are provided on both side walls inside the drag slider 301. The clamping members 303 on the bushing 302 are connected to the inside of the connecting slide rails 12 on the side that are far apart from each other. The clamping members 303 are always in contact with the connecting slide rails 12. When the drive rod 308 moves the drag slider 301 toward the direction closer to the second conveying mechanism 102, the bushing 302 moves away from the second conveying mechanism 102 relative to the drag slider 301. At this time, the spring is compressed, and the clamping members 303 tend to move away from each other, so that they can leave the clamping of the metal wire. This allows the drag cutting assembly 3 to be temporarily separated from the metal wire to avoid blocking the conveying part 1 from conveying the metal wire.
[0030] To equidistantly cut the conveyed metal wire, a cutting assembly 4 is provided on the side of the drag slider 301 away from the second conveying mechanism 102. The cutting assembly is as follows: Figure 8 As shown, it consists of a fixed inclined blade at the bottom and a rotatable rotating blade at the top. The rotating blade cuts the metal wire under the pressure of a cam driven by a top motor. To ensure that the metal wire is cut when the drive rod 308 is furthest from the second conveying mechanism 102 as the rotating wheel 305 rotates, a laser emitter can be installed on the side of the connecting drive block 307 furthest from the drive rod 308, and a sensor receiver can be installed inside the mounting housing 304 on the side where the rotating wheel 305 is installed. When the connecting drive block 307 moves to its furthest point from the second conveying mechanism 102, as... Figure 6 and Figure 7 As shown, the corresponding sensor receiver can receive the laser emitted by the laser emitter. At this time, the motor that drives the cam of the slitting component 4 to rotate immediately rotates, causing the cam to rotate one revolution, so that the slitting component can cut the metal wire once. The slitting operation can be operated with a PLC control system, and the speed and other parameters can be adjusted using the control panel on the base 5.
[0031] In a specific implementation of this invention, one end of the metal wire is first passed between the extrusion rollers 7 of the first conveying mechanism 101, passing through the center of the rotating frame 201, so that all the straightening rollers 202 contact the surface of the metal wire to be straightened. Driven by the drive unit behind the straightening rollers 202, the linkage gears 8 connected behind the upper and lower straightening rollers 202 mesh with each other, and the straightening rollers 202 rotate at the same speed. The metal wire is stuck in the groove on the surface of the straightening rollers 202. After the metal wire passes through the center of the bushing 302, it extends to the other end of the base 5. The conveying and straightening device is started, and the rotating wheel 305 starts to rotate. The dragging slider 301 in the dragging and cutting assembly 3 moves back and forth, moving the bushing 302. The bushing 302 achieves the clamping and releasing operation of the clamping member 303 through the mutual misalignment between itself and the dragging slider 301. The metal wire is conveyed through the grooves on the surface of the extrusion roller 7. The dragging and slitting assembly 3 works in conjunction with the extrusion roller 7 to drag and convey the metal wire, ensuring continuous conveying of the metal wire, reducing slippage during the conveying process, and ensuring the accuracy of the fixed-distance slitting length of the metal wire.
[0032] Second embodiment: like Figure 6 and Figure 7 As shown, based on the first embodiment, the present invention provides several mounting holes 306 on the surface of the rotating wheel 305. Taking four mounting holes 306 as an example, the distances of the four mounting holes 306 from the center of the rotating wheel 305 are different. Therefore, the distances that the crank, composed of the rotating wheel 305 and the connecting drive block 307, drives the dragging slider 301 to reciprocate are different. The dragging and cutting assembly 3 can handle different lengths of metal wire dragging, conveying, and cutting. The mounting holes 306 on the dragging slider 301 can be disassembled and adjusted in batches according to the specific required length. The positions of the mounting holes 306 can be set according to the length of the metal wire to be cut, so as to meet the cutting of metal wires of different lengths.
[0033] Simultaneously, the laser generator installed on the side of the connecting drive block 307 near the rotating wheel 307 and the mounting housing 304 requires four receivers to be installed on the side of the mounting housing 304 where the rotating wheel 307 is mounted, as the rotating wheel 307 rotates. The distance of the four receivers from the center of the rotating wheel 305 is the same as the distance between each mounting hole 306 and the center of the rotating wheel 306. When the connecting drive block 307 moves to its furthest point from the second conveying mechanism 102 as the rotating wheel 305 rotates, the slitting assembly 4 cuts the metal wire, completing the rolling straightening, dragging conveying, and fixed-distance slitting of the metal wire.
[0034] In summary, the alloy wire conveying and straightening device of the present invention has the following advantages: I. The alloy wire conveying and straightening device mainly includes: an extrusion conveying section 1, a straightening section 2, a dragging and slitting assembly 3, a slitting component 4, and a base 5. The dragging slider 301 in the dragging and slitting assembly 3 reciprocates along the direction of wire conveying via a crank composed of a rotating wheel 305 and a drive rod 308. The bushing 302, inside the dragging slider 301, moves relative to the dragging slider 301 in a tendency to move away from it. This tendency allows for the extrusion of the clamping member 303 or for the clamping members 303 to separate, releasing the metal wire from its clamping state. This ensures that the dragging slider 301 moves along the positive direction of wire conveying, assisting in the conveying of the metal wire, reducing slippage caused by surface damage after lubrication during conveying, increasing the continuity of wire conveying, and ensuring the accuracy of the wire conveying and slitting length.
[0035] Second, by using the mounting holes 306 on the surface of the rotating wheel 305 that are at different distances from the center of the rotating wheel 305, the position of the connecting drive block 307 is adjusted. In accordance with the length of the metal wire to be cut, the distance of the drag slider 301 reciprocating is adjusted. Through mechanical distance setting, the tolerance of the metal wire cutting length is made smaller.
[0036] The PLC control system used in the equipment to control the motor speed and the opening and closing of various electrical components is common knowledge to those skilled in the art, and therefore will not be described in detail here.
