Description

Technical Field

[0001] This invention relates to the field of metal wire processing technology, specifically to a metal wire straightening device. Background Technology

[0002] After metal wire is processed and formed, it is bent and coiled to facilitate transportation and storage. However, when the metal wire needs to be used, this bent state cannot meet the requirements of straightness, dimensional accuracy or assembly process. Therefore, the bent metal wire must be straightened before use to restore its straight shape and ensure the quality of subsequent processing.

[0003] Currently, when straightening metal wires using existing straightening devices, the metal wires are prone to axial torsion during the process, causing the bent parts of the wires to roll out of the effective straightening area of ​​the straightening rollers. This results in incomplete straightening of the metal wires, leaving them bent even after straightening, which seriously affects the straightening effect and product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a metal wire straightening device to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A metal wire straightening device includes a base and a mounting frame disposed on the base. A plurality of straightening components are arranged sequentially in the mounting frame. A detection component is disposed on the base between two adjacent straightening components in one group. A traction component is disposed on the base. The straightening component includes two horizontal straightening rollers and two vertical straightening rollers that are perpendicular to each other.

[0007] Both the horizontal and vertical straightening rollers include a roller frame and multiple grooves arranged in a circumferential array on the outside of the roller frame. A straightening block is slidably connected in each groove. A rotating wheel is rotatably connected to both ends of each groove. A baffle is fixedly installed at both ends of each groove inside the two rotating wheels. A first spring is connected between each end of each straightening block and the two baffles. A connecting belt is sleeved on the outside of the two rotating wheels, with both ends fixedly connected to the ends of the straightening blocks. A second magnetic block is fixed in the middle of the roller frame. A first magnetic block that magnetically attracts the second magnetic block is fixedly connected to the bottom of the connecting belt.

[0008] In a preferred embodiment of the metal wire straightening device of the present invention, a guide rod is fixedly connected between the two baffles, the guide rod slides through the straightening block, and the first spring is sleeved on the outside of the guide rod.

[0009] In a preferred embodiment of the metal wire straightening device of the present invention, the width of the connecting strip is equal to the width of the groove opening.

[0010] In a preferred embodiment of the metal wire straightening device of the present invention, the traction assembly includes a traction frame and a drive wheel rotatably disposed within the traction frame. A third slide is slidably connected within the traction frame, and a pressure wheel is rotatably connected within the third slide. The pressure wheel is located directly above the drive wheel.

[0011] In a preferred embodiment of the metal wire straightening device of the present invention, the detection component includes a detection frame and a plurality of detection blocks evenly distributed circumferentially. Each of the plurality of detection blocks has a sliding rod that slides through the detection frame fixedly installed on one side. A second spring is connected between one end of the sliding rod and the detection frame, and a displacement sensor is fixed to one end of the sliding rod.

[0012] In a preferred embodiment of the metal wire straightening device of the present invention, a first slide is vertically slidably connected inside the mounting frame, one of the horizontal straightening rollers is rotatably connected to the mounting frame, and the other horizontal straightening roller is rotatably connected inside the first slide.

[0013] In a preferred embodiment of the metal wire straightening device of the present invention, a rotating drum is rotatably connected to the mounting frame, and a lead screw is fixedly connected to the top of the first slide, the lead screw being screwed through the rotating drum.

[0014] As a preferred embodiment of the metal wire straightening device of the present invention, the mounting frame has two second slides that are symmetrically and horizontally slidably connected, and two vertical straightening rollers are respectively rotatably connected to the two second slides.

[0015] In a preferred embodiment of the metal wire straightening device of the present invention, a double-headed screw is rotatably connected inside the mounting frame, and two second slides are respectively screwed onto the two ends of the double-headed screw.

[0016] In a preferred embodiment of the metal wire straightening device of the present invention, a first worm gear is coaxially fixed on the outer side of the rotating drum, a second worm gear is coaxially fixed on the outer side of the double-ended screw, and a worm is rotatably provided inside the mounting frame, wherein both the first worm gear and the second worm gear mesh with the worm for transmission.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the metal wire passes through multiple straightening components in sequence, so that the metal wire alternately passes through multiple sets of horizontal and vertical straightening rollers. The horizontal and vertical straightening rollers straighten the metal wire by squeezing from mutually perpendicular directions. This allows the bent part of the metal wire to be straightened by the squeezing force in another direction even after axial torsion occurs during the straightening process, thereby ensuring the straightness of the straightened metal wire and the production quality of subsequent products.

[0019] 2. This invention uses a detection block to detect whether the metal wire is still bent after being straightened by the straightening component in front of the detection component. If bending is detected, the main controller can automatically reduce the roller gap of the straightening component according to the offset distance of the detection block to increase the straightening pressure. Subsequently, the metal wire continues to pass through the straightening component located behind the detection component for straightening again to ensure the straightening effect of the metal wire.

[0020] 3. During the straightening process of metal wire, when the metal wire is pulled out from the coiled state, the wire will generate a torsional force along its axial direction, causing relative sliding between the metal wire and the straightening roller. This can easily lead to continuous spiral-shaped straightening damage on the surface of the metal wire, and in severe cases, it can even cause the metal wire to be damaged and scrapped. In the process of straightening metal wire, if the metal wire is axially tortuous, the static friction between the metal wire and the straightening block will cause the axially tortuous metal wire to drive the straightening block to slide along the slide groove, thereby effectively avoiding the axial torsion of the wire relative to the roller body during straightening, which would cause damage to the surface of the wire. This reduces the probability of straightening damage to the metal wire and reduces material waste.

[0021] 4. After the straightening block separates from the metal wire as it rotates with the roller frame, it is reset by the first spring. However, the plastic deformation of the metal wire during straightening and bending generates heat, which is transferred to the first spring through the straightening block. Furthermore, the first spring's constant reciprocating expansion and contraction during straightening makes it prone to fatigue deformation, preventing the straightening block from fully resetting. This leads to premature separation of the straightening block from the metal wire in subsequent straightening processes, resulting in straightening failure. In this invention, after the first spring fatigues and deforms, it can only move the straightening block to near the reset position. At this point, the magnetic attraction between the second and first magnetic blocks on the roller frame causes the first magnetic block to pull the connecting belt, thereby moving the straightening block. Thus, after the first spring fatigues and deforms, the magnetic attraction of the first and second magnetic blocks forces the connecting belt to pull the straightening block for forced reset, ensuring effective subsequent straightening while reducing equipment maintenance frequency.

[0022] 5. When the fatigue deformation of the first spring is too large, causing the straightening block to deviate too much, the magnetic attraction of the first magnetic block and the second magnetic block cannot achieve the forced reset of the straightening block. However, at this time, the deviation of the straightening block on the roller frame is already visible to the naked eye. Therefore, it is possible to determine whether the first spring needs to be maintained or replaced by observing the deviation of the straightening block, making the maintenance and repair process of the equipment more convenient.

[0023] 6. The width of the connecting belt is equal to the width of the chute opening, so that the connecting belt always tightly seals the chute opening when the straightening block moves in the chute, thereby preventing external dust, debris and other impurities from entering the chute, preventing obstruction of the straightening block's movement, ensuring the smooth sliding of the straightening block, and thus reducing the risk of straightening damage to the metal wire.

[0038] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0039] Example 1, referring to Figure 1-13 The first embodiment of the present invention provides a metal wire processing straightening device, which includes a base 1 and a mounting frame 2 disposed on the base 1. A plurality of straightening components are arranged sequentially in the mounting frame 2. A detection component is disposed on the base 1 between two adjacent straightening components. A traction component is disposed on the base 1. The straightening component includes two horizontal straightening rollers and two vertical straightening rollers that are perpendicular to each other.

[0040] Both the horizontal and vertical straightening rollers include a roller frame 24 and multiple grooves 242 arranged in a circumferential array on the outside of the roller frame 24. A straightening block 241 is slidably connected in each groove 242. A rotating wheel 246 is rotatably connected to both ends of each groove 242. A baffle 249 is fixedly installed at both ends of each groove 242 inside the two rotating wheels 246. A first spring 247 is connected between each end of each straightening block 241 and the two baffles 249. A connecting belt 243 is sleeved on the outside of the two rotating wheels 246, with both ends fixedly connected to the ends of the straightening block 241. A second magnetic block 245 is fixed in the middle of the roller frame 24. A first magnetic block 244 that magnetically engages with the second magnetic block 245 is fixedly connected to the bottom of the connecting belt 243.

[0041] A guide rod 248 is fixedly connected between the two baffles 249. The guide rod 248 slides through the straightening block 241, and the first spring 247 is sleeved on the outside of the guide rod 248.

[0042] The width of the connecting strip 243 is equal to the width of the opening of the groove 242.

[0043] During use, the metal wire passes sequentially through multiple straightening components within the mounting frame 2, causing it to alternately pass through multiple sets of horizontal and vertical straightening rollers. Each set of horizontal straightening rollers applies a vertical straightening force to the metal wire, while each set of vertical straightening rollers applies a horizontal straightening force. Then, one end of the metal wire passes through a traction component, which clamps and pulls the wire, causing it to move within the multiple straightening components. In other words, the metal wire alternately passes through multiple sets of horizontal and vertical straightening rollers. When the bent portion of the metal wire is subjected to pressure from one set of straightening rollers, it undergoes axial torsion. At this time, the straightening rollers in the other direction can still effectively squeeze and straighten the bent portion, thereby ensuring the straightness of the straightened metal wire and the production quality of subsequent products.

[0044] During the straightening process of metal wire, a detection component located between two adjacent straightening components is used to detect the straightening effect after the straightening component in front of the detection component has straightened the wire. Its main purpose is to detect whether the metal wire is still bent. If the detection component detects a bend, the main controller can adjust the roller gap of the straightening component according to the detection data. If the metal wire is still bent, it indicates that its straightening force is insufficient, resulting in insufficient straightening of the metal wire. At this time, the roller gap needs to be reduced to increase the straightening pressure. Subsequently, the straightening component located behind the detection component can be used to straighten the still bent metal wire again to ensure the straightening effect of the metal wire.

[0045] In this embodiment, when the metal wire is being straightened, as it is pulled out from the coiled state, the wire will generate a torsional force along its axial direction, causing relative sliding between the metal wire and the straightening roller. This can easily lead to continuous spiral-shaped straightening damage on the surface of the metal wire, and in severe cases, it can even cause the metal wire to be damaged and scrapped.

[0046] In this invention, when the metal wire undergoes axial torsion during the straightening process, a certain static friction force exists between the metal wire and the straightening block 241 due to the presence of the straightening force. This causes the metal wire to move the straightening block 241 that is in contact with the metal wire, allowing the straightening block 241 to slide along the groove 242 on the corresponding roller frame 24. This effectively avoids sliding friction between the metal wire and the straightening block 241, thereby effectively preventing axial torsion of the wire relative to the roller body during straightening, which could cause damage (spiral straightening damage) to the wire surface, reducing material waste. Furthermore, the straightening blocks 241 on both sides of the metal wire can be moved, ensuring the straightening position of the metal wire and guaranteeing the straightening effect.

[0047] As the metal wire moves the straightening block 241, the straightening block 241 compresses one of the first springs 247 and stretches the other. Simultaneously, the straightening block 241 causes the connecting belt 243 to rotate outside the two rollers 246, separating the first magnetic block 244 from the second magnetic block 245 on the roller frame 24. The first magnetic block 244 moves with the connecting belt 243 within the chute 242. Then, as the straightening block 241 rotates along the roller frame 24 via the chute 242, it finally separates from the metal wire. At this point, the combined compression and tension of the two first springs 247 on both sides of the straightening block 241 causes it to move along the chute 242 towards the center of the roller frame 24 for resetting. This ensures that the straightening block 241 can continue to move along the chute 242 during subsequent straightening processes, preventing spiral-shaped damage and ensuring stable equipment operation.

[0048] During the straightening process of the metal wire, when the metal wire is straightened and bent, the internal molecules are squeezed and rubbed to generate heat when plastic deformation occurs. The heat is transferred to the first spring 247 through the straightening block 241. The two first springs 247 reciprocate and expand during the straightening process, which makes the first springs 247 prone to fatigue deformation. This leads to a reduction in the elastic force of the first springs 247, which in turn causes the straightening block 241 to fail to fully reset along the slide. The inability of the straightening block 241 to fully reset will cause the straightening block 241 to move along the slide 242 in the subsequent straightening process. As the distance it moves is shorter, the straightening block 241 will separate from the metal wire in advance, making it impossible for the straightening block 241 to straighten this part of the metal wire.

[0049] In this embodiment, after the first spring 247 is fatigued and deformed, the elastic force of the first spring 247 can only move the straightening block 241 to near the fully reset position. At this time, there is a magnetic attraction between the second magnetic block 245 and the first magnetic block 244 on the roller frame 24, which causes the second magnetic block 245 to pull the first magnetic block 244 closer to the second magnetic block 245. This causes the first magnetic block 244 to pull the connecting belt 243 to move, causing the connecting belt 243 to rotate outside the two rotating wheels 246, thereby causing the connecting belt 243 to move. When the moving straightening block 241 moves, and the first magnetic block 244 and the second magnetic block 245 are fully magnetically attracted and attached, the connecting belt 243 drives the straightening block 241 to reset. Thus, after the fatigue deformation of the first spring 247, the magnetic attraction force of the first magnetic block 244 and the second magnetic block 245 causes the first magnetic block 244 to drive the connecting belt 243 to move, thereby causing the connecting belt 243 to pull the straightening block 241 to force reset, ensuring that the subsequent straightening process is carried out effectively, while reducing the maintenance frequency of the equipment and improving production efficiency.

[0050] When excessive fatigue deformation of the first spring 247 causes excessive offset of the straightening block 241, the distance between the first magnetic block 244 and the second magnetic block 245 is too far. The magnetic attraction of the first magnetic block 244 and the second magnetic block 245 is no longer sufficient to make the connecting belt 243 move the straightening block 241, thus making it impossible to force the straightening block 241 to reset. However, the offset of the straightening block 241 on the roller frame 24 is already visible to the naked eye. Based on this, the staff can determine whether the first spring 247 needs to be maintained or replaced by observing the offset of the straightening block 241 during maintenance, thereby making the maintenance and repair process of the equipment more convenient.

[0051] In addition, the width of the connecting strip 243 is equal to the width of the opening of the slide groove 242, so that when the connecting strip 243 moves with the straightening block 241 in the slide groove 242, the connecting strip 243 always tightly seals the opening of the slide groove 242, which can prevent external dust, debris and other impurities from entering the slide groove 242, prevent dust, debris and other impurities from hindering the movement of the straightening block 241 in the slide groove 242, ensure the smooth sliding of the straightening block 241, and thus reduce the risk of straightening damage to the metal wire.

[0052] In summary, this embodiment fully considers maintenance convenience and long-term operational stability in its structural design. The modular design of the straightening block 241 makes it easier to replace individual straightening units without disassembling the overall roller frame 24. The first magnetic block 244 and the second magnetic block 245 not only serve as compensation mechanisms for the failure of the first spring 247, but their working status can also serve as a visual indicator of the lifespan of the first spring 247. The continuous sealing protection of the opening of the slide groove 242 by the connecting belt 243 effectively solves the problem of dust, oil and other pollutants invading precision sliding parts in industrial settings, significantly extending the service life of key moving parts and effectively improving production efficiency.

[0053] Example 2, refer to Figure 1-5 and Figure 13 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0054] The detection assembly includes a detection frame 4 and multiple detection blocks 41 evenly distributed around the circumference. Each of the multiple detection blocks 41 has a sliding rod 42 fixedly installed on one side, which slides through the detection frame 4. A second spring 43 is connected between one end of the sliding rod 42 and the detection frame 4. A displacement sensor is fixed to one end of the sliding rod 42.

[0055] The mounting frame 2 has a first slide 21 vertically slidably connected inside it. One of the horizontal straightening rollers is rotatably connected to the mounting frame 2, and the other horizontal straightening roller is rotatably connected inside the first slide 21.

[0056] The rotating drum 212 is rotatably connected to the mounting bracket 2, and the top of the first slide 21 is fixedly connected to the lead screw 211, which screws through the rotating drum 212.

[0057] There are two second slides 22 that are symmetrically and horizontally connected within the mounting frame 2, and two vertical straightening rollers are rotatably connected to the two second slides 22 respectively.

[0058] A double-ended screw 221 is rotatably connected inside the mounting bracket 2, and two second slides 22 are respectively screwed to the two ends of the double-ended screw 221.

[0059] A first worm gear 213 is coaxially fixed on the outer side of the rotating drum 212, and a second worm gear 222 is coaxially fixed on the outer side of the double-headed screw 221. A worm 23 is rotatably provided inside the mounting bracket 2. Both the first worm gear 213 and the second worm gear 222 mesh with the worm 23 for transmission.

[0060] During use, the metal wire passes through multiple straightening components and between multiple detection blocks 41 of the detection component. After the metal wire is straightened by multiple straightening components in front of the detection component, it passes between multiple detection blocks 41. If the metal wire is not straightened enough, the surface of the metal wire will be bent. The bending of the metal wire surface will push the corresponding detection block 41 to move, thereby causing the detection block 41 to push the slide bar 42 to move. At the same time, the slide bar 42 and the detection frame 4 stretch the second spring 43. When the slide bar 42 moves, it drives the displacement sensor to move. The displacement sensor at the end of the slide bar 42 transmits the detection data to the main controller. Then the main controller controls the external power supply to drive the worm gear 23 to rotate. When the worm gear 23 rotates, it drives the first worm wheel 213 and the second worm wheel 222 to rotate through meshing transmission.

[0061] When the first worm gear 213 rotates, it drives the rotating drum 212 to rotate, which causes the screw 211 connected inside the rotating drum 212 to move downward, thereby driving the first slide 21 to move the horizontal straightening roller downward, reducing the roller gap between the two horizontal straightening rollers.

[0062] When the second worm gear 222 rotates, it drives the double-headed screw 221 to rotate, thereby causing the two second carriages 22 connected at both ends of the double-headed screw 221 to move toward the middle, reducing the gap between the two vertical straightening rollers.

[0063] In this way, the external power supply is controlled by the main controller to drive the worm 23 to rotate, thereby synchronously reducing the gap between each set of horizontal straightening rollers and each set of vertical straightening rollers, thereby increasing the straightening force on the metal wire. Subsequently, the straightening component located behind the detection component can be used to straighten the still bent metal wire again by the straightening component with the reduced gap between the rollers, ensuring the straightening effect of the metal wire.

[0064] In summary, the detection block 41 detects whether the metal wire remains bent after being straightened by the straightening assembly in front of the detection component. If bending is detected, data is transmitted to the external main controller based on the displacement sensor at the end of the slide bar 42. The main controller automatically drives the worm gear 23 according to the offset distance of the detection block 41, thereby reducing the roller gap of the straightening assembly through the first worm wheel 213 and the second worm wheel 222 to increase the straightening pressure. Subsequently, the metal wire continues to be straightened again by the traction assembly through the straightening assembly located behind the detection component, thus ensuring that the metal wire obtains a good straightening effect. The main controller mentioned in this article can be a conventional known device such as a computer, which will not be elaborated upon here.

[0065] The remaining structure is the same as that in Example 1.

[0066] Example 3, referring to Figure 1-4This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0067] The traction assembly includes a traction frame 3 and a drive wheel 32 rotatably disposed within the traction frame 3. A third slide 33 is slidably connected within the traction frame 3, and a pressure wheel 31 is rotatably connected within the third slide 33. The pressure wheel 31 is located directly above the drive wheel 32.

[0068] A hydraulic push rod is fixedly installed on the traction frame 3, and the telescopic end of the hydraulic push rod is fixedly connected to the third slide 33.

[0069] During use, after the metal wire passes through multiple straightening components, the hydraulic push rod is activated to retract the telescopic end, causing the third slide 33 to move the pressure roller 31 upward, facilitating the insertion of the metal wire. Then, the metal wire passes between the pressure roller 31 and the drive wheel 32 of the traction component. The hydraulic push rod is then activated to push out the telescopic end, causing the third slide 33 to move the pressure roller 31 downward, so that the pressure roller 31 and the drive wheel 32 press the metal wire together. Then, the drive wheel 32 is driven to rotate by an external motor, thereby moving the metal wire through the friction between the drive wheel 32, the pressure roller 31 and the metal wire, thus achieving the clamping and traction of the metal wire.

[0070] The remaining structure is the same as that in Example 2.
