Description

Technical Field

[0001] This utility model relates to the technical field of straightening machine equipment, and in particular to an improved feeding wheel adjustment structure for a wire feeding device. Background Technology

[0002] A wire straightening machine, also called a wire straightening and cutting machine, is mainly used to straighten coiled bar stock (iron or steel wire) and cut it to a fixed length to meet production requirements, facilitate further processing of the workpiece, and provide convenient operation. A straightening machine mainly consists of a wire feeding mechanism, a straightening mechanism, and a cutting mechanism. The wire feeding mechanism precisely and stably feeds the coiled bar stock into the straightening machine. During operation, the wire feeding mechanism drives the feed through the friction between the feeding wheel and the surface of the bar stock. Simultaneously, in conjunction with adjusting plates, guiding devices, and other components, it strictly controls the material's conveying direction and speed to ensure uniform, linear motion and avoid deviation or jamming.

[0003] For example, a wire feeding mechanism for a straightening machine disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN212884736U) includes a wire feeding frame and wire feeding wheels set on the wire feeding frame. There are at least two sets of wire feeding wheels. Each set of wire feeding wheels includes a driving wheel and a driven wheel. The driving wheel and the driven wheel are parallel and spaced apart. The driving wheel and the driven wheel are respectively provided with a corresponding feeding groove. The wire feeding frame is also provided with a translation device. The translation device is used to adjust the horizontal position of the wire feeding wheel relative to the wire feeding frame. The translation device includes a screw and a clamping plate. There are two clamping plates. The two clamping plates are respectively abutted against the two ends of the wire feeding wheel. The two clamping plates are connected by a pull rod.

[0004] However, the existing straightening machine feeding mechanism disclosed above uses two clamping plates located at both ends of the feeding wheel for its translation device, and the two clamping plates are connected by a pull rod to achieve horizontal adjustment of the feeding wheel. This structure relies on the cooperation of the double clamping plates and the pull rod to complete the adjustment function, resulting in a complex overall structure of the feeding mechanism. This not only increases the number of parts and the assembly difficulty, but also increases the production and manufacturing costs, leading to structural redundancy and high costs in practical applications.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this invention is to solve the problem that frequent abnormal friction between the feed wheel and the chuck in the prior art leads to a reduction in the service life of the feed wheel and the chuck, as well as a decrease in equipment accuracy, a deterioration in operational stability, and the occurrence of equipment vibration and noise. Therefore, an improved feed wheel adjustment structure for the wire feeding device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An improved feed wheel adjustment structure for a wire feeding device is disclosed. The wire feeding device includes a frame, a power shaft, and a feed wheel. The power shaft is mounted on the frame, and the feed wheel is sleeved on the outside of the power shaft. The feed wheel is circumferentially connected to the power shaft and can slide axially along the power shaft. The adjustment structure includes an adjustment plate and a limiting member. The adjustment plate is located at one end of the feed wheel, and the end of the feed wheel is provided with a connecting portion. The adjustment plate has a connecting hole that mates with the connecting portion. The connecting portion passes through the connecting hole, and the mate between the connecting portion and the connecting hole allows the feed wheel to rotate freely circumferentially relative to the adjustment plate. The limiting member is connected to the connecting portion and is used to limit the axial degree of freedom of the feed wheel relative to the adjustment plate.

[0009] Furthermore, a limiting bearing is provided between the adjusting plate and the wire feeding wheel and / or between the adjusting plate and the limiting member, and the limiting bearing is sleeved on the outside of the connecting part.

[0010] Furthermore, the limiting bearing is a tapered bearing.

[0011] Furthermore, the limiting bearing creates an axial gap between the adjusting plate and the wire feeding wheel and / or between the adjusting plate and the limiting member.

[0012] Furthermore, the end of the wire feeding wheel and / or the limiting member near the adjusting plate is provided with a receiving groove, and the limiting bearing is disposed in the receiving groove.

[0013] Furthermore, stepped grooves are provided on both sides of the adjusting plate, and the limiting bearing is connected to the stepped grooves.

[0014] Furthermore, the limiting member is fixedly connected to the connecting part.

[0015] Furthermore, the power shaft is provided with a guide protrusion, and the wire feeding wheel is provided with a sliding groove that slides in conjunction with the guide protrusion. The wire feeding wheel and the power shaft achieve anti-rotation engagement through the guide protrusion and the sliding groove.

[0016] Furthermore, a driven shaft is rotatably mounted on the frame, and a driven wheel is sleeved on the outside of the driven shaft. The driven wheel is circumferentially connected to the driven shaft, and the driven wheel can slide along the axial direction of the driven shaft. The wire feeding wheel and the driven wheel are respectively provided with corresponding feeding grooves.

[0017] Furthermore, both ends of the wire feeding wheel are provided with stepped portions, and the width between the stepped portions at both ends of the wire feeding wheel is adapted to the width of the driven wheel; when the adjusting plate drives the wire feeding wheel to move axially, the wire feeding wheel drives the driven wheel to move axially synchronously through the stepped portions.

[0018] The beneficial effects of this utility model after adopting the above structure are as follows:

[0019] (1) The present invention discloses an improved feed wheel adjustment structure for a wire feeding device. The wire feeding device includes a frame, a power shaft, and a wire feeding wheel. The adjustment structure includes an adjustment plate and a limiting member. The adjustment plate is located at one end of the wire feeding wheel. A connecting part is provided at the end of the wire feeding wheel. The adjustment plate has a connecting hole that cooperates with the connecting part. The connecting part passes through the connecting hole. The cooperation between the connecting part and the connecting hole allows the wire feeding wheel to rotate freely in the circumferential direction relative to the adjustment plate. The limiting member is connected to the connecting part and is used to limit the axial degree of freedom of the wire feeding wheel relative to the adjustment plate. The present invention achieves the adjustment of the horizontal position of the wire feeding wheel through an adjustment plate. The adjustment plate is provided at one end of the wire feeding wheel. The wire feeding wheel can rotate freely in the circumferential direction relative to the adjustment plate, and the axial degree of freedom of the wire feeding wheel relative to the adjustment plate is limited by the limiting member.

[0020] (2) The improved feeding wheel adjustment structure of the wire feeding device of this utility model includes a limiting bearing abutting between the adjusting plate and the wire feeding wheel and / or between the adjusting plate and the limiting member, and the limiting bearing is sleeved on the outside of the connecting part. The limiting bearing creates an axial gap between the adjusting plate and the wire feeding wheel and / or between the adjusting plate and the limiting member. The limiting bearing allows the wire feeding wheel and / or the limiting member to rotate freely relative to the adjusting plate in the circumferential direction, and restricts the axial degree of freedom of the wire feeding wheel and / or the limiting member relative to the adjusting plate. This structural design effectively solves the abnormal friction between the wire feeding wheel and the adjusting plate caused by the oscillation of the coiled bar material in the wire feeding device, significantly extending the service life of the wire feeding wheel and the adjusting plate; reducing problems such as decreased equipment accuracy, unstable operation, vibration and noise caused by friction, and reducing maintenance costs; at the same time, the stable operating state ensures the working efficiency and production quality of the wire feeding device, effectively improving the overall performance and reliability of the wire feeding device.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] like Figures 1 to 6As shown, an improved feed wheel adjustment structure for a wire feeding device is disclosed. The wire feeding device includes a frame 1, a power shaft 11, and a wire feeding wheel 2. The power shaft 11 is disposed on the frame 1, and the wire feeding wheel 2 is sleeved on the outside of the power shaft 11. The wire feeding wheel 2 is circumferentially connected to the power shaft 11 and can slide along the axial direction of the power shaft 11. The adjustment structure 3 includes an adjustment plate 31 and a limiting member 32. The adjustment plate 31 is located at one end of the wire feeding wheel 2, and a connecting part 21 is provided at the end of the wire feeding wheel 2. The adjustment plate 31 has a connecting hole 312 that cooperates with the connecting part 21. The connecting part 21 passes through the connecting hole 312, and the cooperation between the connecting part 21 and the connecting hole 312 allows the wire feeding wheel 2 to rotate freely in the circumferential direction relative to the adjustment plate 31. The limiting member 32 is connected to the connecting part 21 and is used to limit the axial degree of freedom of the wire feeding wheel 2 relative to the adjustment plate 31. The limiting member 32 is fixedly connected to the connecting part 21.

[0038] Based on the above embodiments, this utility model provides an improved feeding wheel adjustment structure for a wire feeding device. The wire feeding device includes a frame 1, a power shaft 11, and a wire feeding wheel 2. The adjustment structure 3 includes an adjustment plate 31 and a limiting member 32. The adjustment plate 31 is located at one end of the wire feeding wheel 2. The end of the wire feeding wheel 2 is provided with a connecting part 21. The adjustment plate 31 is provided with a connecting hole 312 that cooperates with the connecting part 21. The connecting part 21 passes through the connecting hole 312. The cooperation between the connecting part 21 and the connecting hole 312 allows the wire feeding wheel 2 to rotate freely in the circumferential direction relative to the adjustment plate 31. The limiting member 32 is connected to the connecting part 21 and is used to limit the axial degree of freedom of the wire feeding wheel 2 relative to the adjustment plate 31. This invention uses an adjusting plate 31 to adjust the horizontal position of the wire feeding wheel 2. The adjusting plate 31 is located at one end of the wire feeding wheel 2. The wire feeding wheel 2 can rotate freely in the circumferential direction relative to the adjusting plate 31, and the axial degree of freedom of the wire feeding wheel 2 relative to the adjusting plate 31 is restricted by a limiting member 32. This structural design simplifies the adjusting structure 3, effectively improves assembly efficiency, reduces the number of parts, lowers material costs and processing difficulty, and optimizes production costs while ensuring functionality.

[0039] In this embodiment, the connecting part 21 can be integrally formed with the wire feeding wheel 2, or it can be separately formed from the wire feeding wheel 2 and fixedly connected. The limiting member 32 and the adjusting plate 31 are sequentially sleeved on the connecting part 21 from the outside to the inside. The limiting member 32 is fixedly connected to the connecting part 21, specifically through a threaded connection or other fixed connection methods. Figure 3 As shown, when the adjusting screw 33 is rotated by operating the handwheel 331, the adjusting plate 31 moves, and the adjusting plate 31 in turn drives the wire feeding wheel 2 to move together in the horizontal direction.

[0040] In another preferred embodiment of this utility model, a limiting bearing 4 is provided between the adjusting plate 31 and the wire feeding wheel 2 and / or between the adjusting plate 31 and the limiting member 32, and the limiting bearing 4 is sleeved on the outside of the connecting part 21. The limiting bearing 4 creates an axial gap between the adjusting plate 31 and the wire feeding wheel 2 and / or between the adjusting plate 31 and the limiting member 32. The limiting bearing 4 is a tapered bearing. A receiving groove 22 is provided at one end of the wire feeding wheel 2 and / or the limiting member 32 near the adjusting plate 31, and the limiting bearing 4 is disposed in the receiving groove 22. Stepped grooves 311 are provided on both sides of the adjusting plate 31, and the limiting bearing 4 is connected to the stepped grooves 311.

[0041] In this embodiment, a limiting bearing 4 is provided between the end of the wire feeding wheel 2 and the adjusting plate 31, and this limiting bearing 4 is defined as the first bearing 41. The first bearing 41 allows the wire feeding wheel 2 to rotate freely relative to the adjusting plate 31 in the circumferential direction, and restricts the axial degree of freedom of the wire feeding wheel 2 relative to the adjusting plate 31. The width of the first inner ring 412 and the width of the first outer ring 411 of the first bearing 41 are different, so that a gap is formed between the adjusting plate 31 and the wire feeding wheel 2. The first bearing 41 is embedded in the end of the wire feeding wheel 2, and the first outer ring 411 of the first bearing 41 is connected to the wire feeding wheel 2. The first inner ring 412 of the first bearing 41 extends out of the wire feeding wheel 2 and is connected to the adjusting plate 31. The connection can be a fixed connection or an interference fit.

[0042] In other preferred embodiments, a limiting bearing 4 is provided between the adjusting plate 31 and the limiting member 32, and this limiting bearing 4 is defined as a second bearing 42. The second bearing 42 allows the limiting member 32 to rotate freely relative to the adjusting plate 31 in the circumferential direction, and the second bearing 42 restricts the axial degree of freedom of the adjusting plate 31 relative to the limiting member 32. The width of the second inner ring 422 and the width of the second outer ring 421 of the second bearing 42 are different, so that a gap is formed between the adjusting plate 31 and the limiting member 32. The second bearing 42 is fitted into the side of the limiting member 32 facing the adjusting plate 31, and the second outer ring 421 of the second bearing 42 is connected to the limiting member 32. The second inner ring 422 of the second bearing 42 extends out of the limiting member 32 and is connected to the adjusting plate 31. The connection can be a fixed connection or an interference fit.

[0043] In a further preferred embodiment, limiting bearings 4 are provided between the adjusting plate 31 and the wire feeding wheel 2, and between the adjusting plate 31 and the limiting member 32. The limiting bearing 4 located between the end of the wire feeding wheel 2 and the adjusting plate 31 is defined as a first bearing 41, and the limiting bearing 4 located between the adjusting plate 31 and the limiting member 32 is defined as a second bearing 42. In this embodiment, as... Figure 3 As shown, a first bearing 41 is provided to ensure a clearance fit between the wire feeding wheel 2 and the adjusting plate 31, and the first bearing 41 restricts the axial freedom of the wire feeding wheel 2 relative to the adjusting plate 31. A second bearing 42 is provided to ensure a clearance fit between the adjusting plate 31 and the limiting member 32, and the second bearing 42 restricts the axial freedom of the adjusting plate 31 relative to the limiting member 32. This structural design effectively solves the abnormal friction between the wire feeding wheel 2 and the adjusting plate 31 caused by the oscillation of the coiled bar material in the wire feeding device, significantly extending the service life of the wire feeding wheel 2 and the adjusting plate 31; reducing problems such as decreased equipment accuracy, unstable operation, vibration and noise caused by friction, and lowering maintenance costs; at the same time, the stable operating state ensures the working efficiency and production quality of the wire feeding device, effectively improving the overall performance and reliability of the wire feeding device.

[0044] See appendix Figure 3 and attached Figure 4 The first bearing 41 improves the smoothness and stability of the rotation of the wire feeding wheel 2 relative to the adjusting plate 31; the second bearing 42 improves the smoothness and stability of the rotation of the limiting member 32 relative to the adjusting plate 31. Both the first bearing 41 and the second bearing 42 are tapered bearings, and they are oriented in the same direction. This structural design improves the load-bearing performance of the first bearing 41 and the second bearing 42. In this embodiment, when the first bearing 41 is fitted into the end of the wire feeding wheel 2, the first inner ring 412 of the first bearing 41 extends out of the wire feeding wheel 2 and engages with the adjusting plate 31, creating a clearance fit between the wire feeding wheel 2 and the adjusting plate 31. When the second bearing 42 is fitted into the side of the limiting member 32 facing the adjusting plate 31, the second inner ring 422 of the second bearing 42 extends out of the limiting member 32 and engages with the adjusting plate 31, creating a clearance fit between the limiting member 32 and the adjusting plate 31.

[0045] In a further preferred embodiment, such as Figures 4 to 6As shown, during assembly, the first bearing 41, adjusting plate 31, second bearing 42, and limiting member 32 are sequentially sleeved on the outside of the connecting part 21 from the inside to the outside. The first bearing 41 is housed in the receiving groove 22 at the end of the wire feeding wheel 2. The depth of the receiving groove 22 is less than the width of the first inner ring 412, thereby making the wire feeding wheel 2 and the adjusting plate 31 in a clearance fit. The second bearing 42 is housed in the receiving groove 22 of the limiting member 32. The depth of the receiving groove 22 is less than the width of the second inner ring 422, thereby making the limiting member 32 and the adjusting plate 31 in a clearance fit.

[0046] In another preferred embodiment of this utility model, the power shaft 11 is provided with a guide protrusion 111, and the wire feeding wheel 2 is provided with a sliding groove 23 that slides in conjunction with the guide protrusion 111. The wire feeding wheel 2 and the power shaft 11 achieve anti-rotation engagement through the guide protrusion 111 and the sliding groove 23. In this embodiment, as... Figure 1 and Figure 5 As shown, the guide ridge 111 provides guidance for the axial movement of the wire feeding wheel 2, and the wire feeding wheel 2 and the power shaft 11 are anti-rotationally engaged through the guide ridge 111 and the slide groove 23.

[0047] In another preferred embodiment of this utility model, a driven shaft 12 is rotatably mounted on the frame 1, and a driven wheel 5 is sleeved on the outside of the driven shaft 12. The driven wheel 5 is circumferentially connected to the driven shaft 12 and can slide along the axial direction of the driven shaft 12. The wire feeding wheel 2 and the driven wheel 5 are each provided with a corresponding feeding groove 24. Both ends of the wire feeding wheel 2 are provided with stepped portions 25, and the width between the stepped portions 25 at both ends of the wire feeding wheel 2 is adapted to the width of the driven wheel 5. When the adjusting plate 31 drives the wire feeding wheel 2 to move axially, the wire feeding wheel 2 drives the driven wheel 5 to move axially synchronously through the stepped portions 25. In this embodiment, as... Figure 3 As shown, both ends of the wire feeding wheel 2 are provided with stepped portions 25. The width between the stepped portions 25 at both ends of the wire feeding wheel 2 is adapted to the width of the driven wheel 5. During assembly, the driven wheel 5 is positioned between the stepped portions 25 at both ends, so that when the wire feeding wheel 2 moves left and right, the driven wheel 5 moves left and right synchronously through the stepped portions 25.

[0048] As another preferred embodiment of this utility model, the adjusting mechanism further includes an adjusting screw 33, which is rotatably mounted on the frame 1; the adjusting screw 33 passes through the adjusting plate 31 and is threadedly connected to the adjusting plate 31. One end of the adjusting screw 33 extends out of the frame 1, and a handwheel 331 is connected to the extended end. Several feeding troughs 24 are arranged side-by-side, and the width of the feeding troughs 24 is different. In this embodiment, as... Figure 2 and Figure 3As shown, several feeding troughs 24 are arranged in parallel, and the width of the feeding troughs 24 is different. Specifically, during operation, different feeding troughs 24 are selected according to the different sizes of the bar stock. By operating the handwheel 331, the adjusting screw 33 is rotated, which in turn causes the adjusting plate 31 to move, which in turn drives the wire feeding wheel 2 to move together, so that the wire feeding wheel 2 and the adjusting plate 31 move synchronously in the horizontal direction, thereby switching to the appropriate feeding trough 24.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
