Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a straightening wheel and a straightening device containing the straightening wheel. Background Technology

[0002] Due to the asymmetrical cross-sectional shape of irregularly shaped wires, they are prone to twisting and bending during production and processing. This leads to scratches and deterioration of the wire shape during machining and heat treatment, making subsequent processing impossible. Currently, to solve the problems of bending and twisting of irregularly shaped wires, a straightening method using circular cross-sections or flat strips is generally adopted. This involves adding a certain number of flat rollers with different spacing and groove gaps, and then adjusting the position of the straightening rollers by a lead screw to straighten the wire.

[0003] However, when straightening metal wires with irregular cross-sections, the slot gap of the straightening wheel is fixed. One type of straightening wheel cannot meet the straightening needs of various specifications of irregularly shaped wires, requiring the replacement of different models of straightening wheels for straightening, resulting in low adaptability. In addition, existing straightening devices have a single straightening method, only guiding the wire in through a guide component and then straightening it through the straightening wheel. The angle of twisting the wire by the straightening wheel is limited, making it impossible to straighten it from multiple angles, resulting in the straightened wire not being completely straight. Utility Model Content

[0004] The purpose of this invention is to provide a straightening wheel and a straightening device containing the straightening wheel to solve the problems in the prior art.

[0005] This utility model provides a straightening wheel, including a shaft, a base, and a top seat. The base is mounted on the shaft and can rotate around the axis of the shaft. The base includes a first body, a second body, and a third body with progressively increasing diameters in a stepped shape. The top seat has a first channel and a second channel along the axial direction. The inner wall of the first channel is threaded to the outer wall of the first body, and the inner wall of the second channel abuts against the outer wall of the second body. When the top seat is rotated, the distance between the opposing surfaces of the top seat and the third body can be adjusted.

[0006] In the straightening wheel described above, preferably, the base has a receiving cavity, and a bearing is disposed in the receiving cavity located at the third body. The outer ring of the bearing is fixedly connected to the third body, and the inner ring of the bearing is fixedly connected to the shaft.

[0008] In the straightening wheel described above, preferably, the straightening wheel further includes a fixing member, and the shaft has a shaft hole along the axial direction. The fixing member passes through the top of the bearing and is connected to the shaft hole.

[0009] This utility model also provides a straightening device containing the above-mentioned straightening rollers, which further includes a first base and a first adjustment component. The first base is provided with two rows of straightening rollers arranged alternately along the wire conveying direction. The first adjustment component is provided for each straightening roller. The first adjustment component is used to drive the two rows of straightening rollers to move relative to or away from each other perpendicular to the wire conveying direction.

[0010] In the straightening device described above, preferably, the first adjusting component includes a slider and an adjusting rod. The slider is disposed on the first base, the shaft is movably connected to the slider, one end of the adjusting rod is connected to the slider, and the other end extends to the outside of the first base.

[0011] In the straightening device described above, preferably, a limit block is provided between adjacent sliders.

[0012] In the straightening device described above, preferably, longitudinal straightening mechanisms are respectively provided on both sides of the first base, including a second base, flat wheels and a second adjustment component.

[0013] In the straightening device described above, preferably, the straightening device further includes two guiding mechanisms, which are respectively disposed on the side of the longitudinal straightening mechanism opposite to the first base along the wire conveying direction. The guiding mechanism includes a third base and a guide roller. The third base is perpendicular to the second base and parallel to the first base. The guide roller is symmetrically disposed on the third base, and the wire can be conveyed between the two guide rollers.

[0014] Compared with the prior art, this utility model uses a threaded connection between the top seat and the base, allowing the top seat to move up and down relative to the base, thereby changing the size of the groove spacing formed between the opposing surfaces of the top seat and the base to adapt to different types of wires and improve the compatibility of the straightening roller. In addition, this utility model also limits the wire routing position by setting two opposing sets of longitudinal straightening mechanisms and guide components to prevent deviation, and works with the straightening roller to straighten irregularly shaped wires from multiple dimensions, improving the straightness of the straightened wires.

[0026] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Traditional straightening rollers 10 straighten the wire by machining annular grooves on the straightening surface that match the wire diameter, thereby increasing the contact area and friction to constrain the wire. For irregularly shaped wires, different wire models require annular grooves with different groove gaps to match them. However, the opening of existing annular grooves is usually fixed. When matching different wire models, all straightening rollers 10 in the straightening section need to be replaced with the appropriate model, resulting in poor compatibility. Furthermore, since there are many straightening rollers 10, the position of each straightening roller 10 needs to be adjusted after replacement to meet the current wire straightening requirements. This not only results in a long debugging cycle but also requires a large amount of manual labor.

[0028] Therefore, see Figures 1-4 As shown, this application provides a straightening wheel, including a shaft 11, a base 12, and a top seat 13. The base 12 is disposed on the shaft 11 and can rotate around the axis of the shaft 11. The base 12 includes a first body 120, a second body 121, and a third body 122 with progressively increasing diameters in a stepped shape. The top seat 13 has a first channel 130 and a second channel 131 along the axial direction. The inner wall of the first channel 130 is threadedly connected to the outer wall of the first body 120, and the inner wall of the second channel 131 abuts against the outer wall of the second body 121. When the top seat 13 is rotated, the distance between the opposing surfaces of the top seat 13 and the third body 122 can be adjusted. In this embodiment, the first body 120, the second body 121, and the third body 122 are all cylindrical. The top seat 13 and the third body 122 have the same diameter. The distance between the opposing surfaces of the top seat 13 and the third body 122 forms the groove spacing of the straightening surface of the straightening wheel 10. The threaded engagement enables micro-level gap adjustment. The distance between the top seat 13 and the third body 122 can be finely adjusted by rotating the top seat 13 according to the thickness of the wire, thereby changing the amount of compression deformation when the wire passes through, thus adapting to different types of wire and improving the compatibility of the straightening wheel 10. The top seat 13 and the base 12 are connected by threads. The outer wall surface of the second body 121 abuts against the inner wall surface of the second channel 131. During the thread tightening process, the coaxiality of the top seat 13 and the base 12 is automatically corrected to avoid manual alignment deviation. Moreover, during the wire conveying process, the groove spacing formed between the top seat 13 and the third body 122 will not change due to wire friction. It should be noted that the outer wall surface of the second body 121 in the slot spacing plays a straightening and compression role on the wire, while the surface of the top seat 13 opposite to the base 12 mainly serves to constrain the wire.

[0029] In this embodiment, see Figure 4As shown, the base 12 has a cavity 123. A bearing 14 is installed in the cavity 123 located at the third body 122. The outer ring of the bearing 14 is fixedly connected to the third body 122, and the inner ring of the bearing 14 is fixedly connected to the shaft 11. The shaft 11 is used to fix the straightening wheel 10 to the straightening device. The base 12 and the top seat 13 can rotate relative to the shaft 11 under the driving action of wire conveying, and the irregular wire is straightened by friction and compression.

[0030] See Figure 4 As shown, a retaining ring 124 is provided at the bottom of the third body 122, and the bottom of the bearing 14 abuts against the retaining ring 124. The retaining ring 124 is used to confine the bearing 14 within the third body 122.

[0031] See Figure 2 As shown, in this embodiment, the straightening wheel 10 further includes a fixing member 15. A shaft hole 110 is provided in the shaft 11 along the axial direction. The fixing member 15 passes through the top of the bearing 14 and connects to the shaft hole 110. The fixing member 15 can be a screw. An annular boss 111 is provided on the shaft 11. The bearing 14 can be fixed integrally with the base 12 and then sleeved on the shaft 11. The boss 111 is used to limit the position of the bearing 14, and the fixing member 15 is used to fix the shaft 11 to the inner ring of the bearing 14.

[0032] See Figures 5-6 As shown, this utility model also provides a straightening device, including the aforementioned straightening rollers 10, a first base 20, and a first adjusting component 21. The first base 20 is provided with two rows of straightening rollers 10 arranged alternately along the wire conveying direction. The first adjusting component 21 is provided for each straightening roller 10 and is used to drive the two rows of straightening rollers 10 to move relative to or away from each other perpendicular to the wire conveying direction. The two rows of straightening rollers 10 are arranged alternately along the wire conveying direction, causing the wire to experience alternating lateral bending forces as it passes through. The alternating arrangement causes the wire to undergo multiple levels of micro-deformation, gradually correcting the bending through strain accumulation, thus achieving progressive straightening and reducing material damage. The first adjusting component 21 is driven independently for each roller and can dynamically match the wire specifications.

[0033] See Figure 6As shown, in this embodiment, the first adjustment component 21 includes a slider 210 and an adjustment rod 211. The slider 210 is mounted on the first base 20, and the shaft 11 is movably connected to the slider 210. One end of the adjustment rod 211 is connected to the slider 210, and the other end extends to the outside of the first base 20. The straightening wheel 10 is located at the front end of the slider 210. The shaft 11 has a thread, and the screw is threadedly connected to the slider 210 for easy disassembly and replacement. The adjustment rod 211 is assembled using a micrometer micron head. The slider 210 has a moving space along the direction perpendicular to the wire conveying. By using the micrometer micron head, the slider 210 can move within the moving space, thereby adjusting the relative distance between two adjacent straightening wheels 10 perpendicular to the wire conveying direction. The micrometer micron head can make micro-adjustments according to the side bending and twisting of the incoming material, thereby realizing the straightening treatment of the metal wire. The structure of the micrometer micron head is existing technology and will not be described in detail here.

[0034] Further, see Figure 6 As shown, a limiting block 22 is provided between adjacent sliders 210. Since the straightening rollers 10 are staggered, there is a gap between adjacent straightening rollers 10. The limiting block 22 fills the gap, ensuring that each straightening roller 10 can only move linearly within the limiting range. In a preferred embodiment, a spring (not shown in the figure) is connected between the opposing limiting block 22 and the slider 210. The spring can act as a buffer during the adjustment of the slider 210.

[0035] See Figure 5 As shown, the two rows of horizontally arranged straightening rollers 10 can only straighten the wire in the horizontal direction, resulting in a limited straightening range and a limited angle of wire twisting. Therefore, in this embodiment, longitudinal straightening mechanisms 30 are respectively arranged on both sides of the first base 20, including a second base 31, flat rollers 32, and a second adjustment component 33. The second base 31 is arranged perpendicular to the first base 20. There are two rows of flat rollers 32, which are arranged alternately on the second base 31 perpendicular to the wire conveying direction. The second adjustment component 33 is provided for each flat roller 32 and is used to drive the two rows of flat rollers 32 to move relative to or away from each other perpendicular to the wire conveying direction. The longitudinal direction of the wire is constrained by the two rows of flat rollers 32 that can move relative to or away from each other. The flat rollers 32 are arranged on both sides of the straightening roller 10 for straightening. The surface of the flat rollers 32 is smooth, so they will not rub against the wire during the wire conveying process and have a certain guiding effect, guiding the wire to the range of the straightening roller 10. In the embodiments provided in this application, the structure of the second adjustment component 33 is the same as that of the first adjustment component 21, and will not be repeated here.

[0036] See Figures 5-6As shown, in this embodiment, the straightening device further includes two guiding mechanisms 40, which are respectively disposed on the side of the longitudinal straightening mechanism 30 away from the first base 20 along the wire conveying direction. Each guiding mechanism 40 includes a third base 41 and guide rollers 42. The third base 41 is perpendicular to the second base 31 and parallel to the first base 20. The guide rollers 42 are symmetrically disposed on the third base 41, allowing the wire to be conveyed between the two guide rollers 42. The guiding mechanism 40 is used to limit the wire conveying direction and prevent deviation. It should be noted that the guiding mechanism 40, the longitudinal straightening mechanism 30, and the straightening wheel 10 should maintain the wire conveying direction on the same horizontal line. As a preferred embodiment, the distance between the two guide rollers 42 is adjustable. By opening a strip-shaped hole in the third base 41, one end of the guide roller 42 extends through the strip-shaped hole to the bottom of the third base 41 and is fixed with bolts. By adjusting the distance between the two guide rollers 42, different types of wire can be accommodated, improving the applicability of the device.

[0037] The wire conveying path of the straightening device includes a straightening wheel 10, longitudinal straightening mechanisms 30 on both sides of the straightening wheel 10, and guide mechanisms 40 on both sides of the longitudinal straightening mechanisms 30. The wire is guided and squeezed in the longitudinal and horizontal directions in sequence along the wire conveying direction, so that the wire is adjusted in multiple dimensions, thereby achieving more precise straightening. Along the wire conveying direction, the guide mechanism 40 at the inlet end serves as a trajectory constraint, while the longitudinal straightening mechanism 30 straightens the wire from slight twisting and ensures smooth wire movement, preventing vibration when entering the intermediate straightening roller 10, which would exacerbate wear and affect the straightening effect. The intermediate straightening roller 10 precisely straightens and deforms the wire through compression and constraint. The adjustable slot spacing of the straightening roller 10 enables straightening operations for metal wires with different sizes and irregular cross-sections. The longitudinal straightening mechanism 30 at the outlet end can perform longitudinal bending straightening on the wire that has been twisted and laterally bent, making the wire straight and preventing abnormal flipping during subsequent processing. The guide mechanism 40 at the end serves as a shaping output. Through the cooperation of multiple straightening mechanisms, the irregular wire is repeatedly bent and deformed from multiple angles, offsetting the original bending stress of the wire and gradually bringing it closer to a straight state.

[0038] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
