Description

Technical Field

[0001] This utility model relates to the technical field of straightening machine equipment, and in particular to a 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 and cut coiled bar stock (iron or steel wire) 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, the feeding direction and speed of the material are strictly controlled 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 wire feeding mechanism of the straightening machine disclosed in the aforementioned prior art requires a gap between the clamping plate and the wire feeding wheel to allow the wire feeding wheel to rotate relative to the clamping plate. In actual operation, due to its coiled shape and internal material stress, the coiled bar stock will exhibit irregular left-right swaying during unwinding and feeding. The lateral force generated by this swaying acts directly on the wire feeding wheel, causing it to deviate from its intended running trajectory and frequently experience abnormal friction with the clamping plate. Continuous friction and wear not only reduce the service life of the wire feeding wheel and clamping plate, leading to decreased equipment accuracy and poor operational stability, but also cause equipment vibration and noise, increasing maintenance costs and severely impacting the working efficiency and production quality of the wire feeding mechanism.

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

[0006] The purpose of this utility model is to solve the problem that the wire feeding wheel and the clamp plate frequently rub abnormally in the existing technology, which leads to a reduction in the service life of the wire feeding wheel and the clamp plate, as well as a decrease in equipment accuracy, a decrease in operational stability, and a problem that can also cause equipment vibration and noise. Therefore, a wire feeding wheel adjustment structure for a wire feeding device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A feeding wheel adjustment structure for a wire feeding device includes a frame, a power shaft, and a feeding wheel. The power shaft is mounted on the frame, and the feeding wheel is sleeved on the outside of the power shaft. The feeding wheel is circumferentially connected to the power shaft and can slide along the axial direction of the power shaft. The adjustment structure includes two limiting plates arranged along the axial direction of the power shaft, with the feeding wheel positioned between the two limiting plates. A limiting bearing is provided between each limiting plate and a corresponding end of the feeding wheel. The limiting bearing allows the feeding wheel to rotate freely relative to the limiting plate in the circumferential direction and restricts the axial freedom of the feeding wheel between the two limiting plates.

[0008] Furthermore, the limiting bearing is a tapered bearing.

[0009] Furthermore, the inner and outer ring widths of the limiting bearing are different, so that an axial gap is formed between the limiting plate and the wire feeding wheel.

[0010] Furthermore, the limiting bearing is embedded in the end of the wire feeding wheel, and the outer ring of the limiting bearing is connected to the wire feeding wheel, while the inner ring of the limiting bearing extends out of the wire feeding wheel and is connected to the limiting plate.

[0011] Furthermore, the limiting bearing is embedded in the side of the limiting plate near the wire feeding wheel, and the outer ring of the limiting bearing is connected to the limiting plate, while the inner ring of the limiting bearing extends out of the limiting plate and is connected to the wire feeding wheel.

[0012] Furthermore, the adjustment structure also includes an adjustment screw, which is rotatably mounted on the frame; the adjustment screw passes through a limiting plate and is threadedly connected to the limiting plate.

[0013] 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. A corresponding feeding groove is opened on the wire feeding wheel and the driven wheel respectively.

[0014] 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 limiting plate drives the wire feeding wheel to move axially, the wire feeding wheel drives the driven wheel to move axially through the stepped portions.

[0015] Furthermore, a guide rod is fixedly installed on the frame, and the guide rod passes through the limiting plate and slides with the limiting plate.

[0016] Furthermore, the limiting plates at both ends of the wire feeding wheel are connected by pull rods.

[0017] The beneficial effects of this utility model after adopting the above structure are as follows: The feeding wheel adjustment structure of the wire feeding device of this utility model includes a frame, a power shaft, and a wire feeding wheel. The adjustment structure includes two limiting plates arranged along the axial direction of the power shaft, with the wire feeding wheel positioned between the two limiting plates. A limiting bearing is provided between each limiting plate and the corresponding end of the wire feeding wheel. The limiting bearing allows the wire feeding wheel to rotate freely relative to the limiting plate in the circumferential direction, and also restricts the axial freedom of the wire feeding wheel between the two limiting plates. This utility model allows the wire feeding wheel to rotate freely relative to the limiting plates in the circumferential direction through the limiting bearing, ensuring that a gap is always formed between the limiting plate and the wire feeding wheel. Simultaneously, the limiting bearing restricts the axial freedom of the wire feeding wheel between the two limiting plates. This structural design effectively solves the problem of wire feeding wheel deviation caused by the swaying of the coiled bar material in the wire feeding device, thereby avoiding abnormal friction between the wire feeding wheel and the limiting plate, significantly extending the service life of the wire feeding wheel and the limiting plate; reducing problems such as decreased equipment precision, 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.

[0028] like Figures 1 to 4 As shown, a feeding wheel adjustment structure for a wire feeding device is disclosed. The wire feeding device includes a frame 1, a power shaft 11, and a feeding wheel 2. The power shaft 11 is disposed on the frame 1, and the feeding wheel 2 is sleeved on the outside of the power shaft 11. The 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 two limiting plates 31 arranged along the axial direction of the power shaft 11, and the feeding wheel 2 is disposed between the two limiting plates 31. A limiting bearing 4 is provided between each limiting plate 31 and the corresponding end of the feeding wheel 2. The limiting bearing 4 allows the feeding wheel 2 to rotate freely relative to the limiting plate 31 in the circumferential direction, and restricts the axial degree of freedom of the feeding wheel 2 between the two limiting plates 31.

[0029] Based on the above embodiments, this utility model provides a 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 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 two limiting plates 31, which are arranged along the axial direction of the power shaft 11. The wire feeding wheel 2 is disposed between the two limiting plates 31. A limiting bearing 4 is provided between each limiting plate 31 and the corresponding end of the wire feeding wheel 2. The limiting bearing 4 allows the wire feeding wheel 2 to rotate freely relative to the limiting plate 31 in the circumferential direction and restricts the axial degree of freedom of the wire feeding wheel 2 between the two limiting plates 31. This invention utilizes a limiting bearing 4 to allow the wire feeding wheel 2 to rotate freely in the circumferential direction relative to the limiting plate 31, while maintaining a gap between the limiting plate 31 and the wire feeding wheel 2. Simultaneously, the limiting bearing 4 restricts the axial freedom of the wire feeding wheel 2 between the two limiting plates 31. This structural design effectively solves the problem of wire feeding wheel 2 deviating due to the swaying of the coiled bar material, thereby avoiding abnormal friction between the wire feeding wheel 2 and the limiting plate 31, significantly extending the service life of both the wire feeding wheel 2 and the limiting plate 31; reducing problems such as decreased equipment precision, unstable operation, vibration, and noise caused by friction, and lowering maintenance costs; at the same time, stable operation ensures the working efficiency and production quality of the wire feeding device, effectively improving the overall performance and reliability of the wire feeding device.

[0030] In another preferred embodiment of this utility model, the limiting bearing 4 is a tapered bearing. The inner ring 42 and the outer ring 41 of the limiting bearing 4 have different widths, so that an axial clearance is formed between the limiting plate 31 and the wire feeding wheel 2. The limiting bearing 4 is embedded in the end of the wire feeding wheel 2, and the outer ring 41 of the limiting bearing 4 is connected to the wire feeding wheel 2, while the inner ring 42 of the limiting bearing 4 extends out of the wire feeding wheel 2 and is connected to the limiting plate 31. In this embodiment, as... Figure 3As shown, the installation of the limiting bearing 4 improves the smoothness and stability of the rotation of the wire feeding wheel 2 relative to the limiting plate 31. The limiting bearing 4 is a tapered bearing, which improves its load-bearing performance. In this embodiment, the limiting bearing 4 is embedded in the end of the wire feeding wheel 2, and the outer ring 41 of the limiting bearing 4 is connected to the wire feeding wheel 2, specifically, it can be a fixed connection or an interference fit; the inner ring 42 of the limiting bearing 4 extends out of the wire feeding wheel 2 and is connected to the limiting plate 31, specifically, it can be a fixed connection or an interference fit, so that an axial clearance is always formed between the limiting plate 31 and the wire feeding wheel 2, and the movement of the wire feeding wheel 2 relative to the limiting plate 31 is restricted. In this embodiment, the aforementioned axial clearance is formed between the end of the wire feeding wheel 2 and the end face of the corresponding limiting plate 31 near the wire feeding wheel 2. Of course, in other preferred embodiments, the limiting bearing 4 can also be embedded on the side of the limiting plate 31 near the wire feeding wheel 2, and the outer ring 41 of the limiting bearing 4 can be connected with the limiting plate 31, and the inner ring 42 of the limiting bearing 4 can extend out of the limiting plate 31 and be connected with the wire feeding wheel 2.

[0031] In another preferred embodiment of this utility model, a driven shaft 12 is rotatably mounted on the frame 1, and a driven wheel 6 is sleeved on the outside of the driven shaft 12. The driven wheel 6 is circumferentially connected to the driven shaft 12 and can slide along the axial direction of the driven shaft 12. A corresponding feeding groove 7 is provided on the wire feeding wheel 2 and the driven wheel 6. Several feeding grooves 7 are arranged side-by-side, and the groove widths of the grooves 7 are different. Both ends of the wire feeding wheel 2 are provided with stepped portions 21, and the width between the stepped portions 21 at both ends of the wire feeding wheel 2 is adapted to the width of the driven wheel 6. When the limiting plate 31 drives the wire feeding wheel 2 to move axially, the wire feeding wheel 2 drives the driven wheel 6 to move axially through the stepped portions 21. The limiting plates 31 at both ends of the wire feeding wheel 2 are connected by a pull rod 34. The adjustment structure 3 further includes an adjustment screw 32, which is rotatably mounted on the frame 1. The adjustment screw 32 passes through a limiting plate 31 and is threadedly connected to the limiting plate 31. One end of the adjustment screw 32 extends out of the frame 1, and a handwheel 321 is connected to the extended end. A guide rod 33 is fixedly mounted on the frame 1, which passes through the limiting plate 31 and slides with the limiting plate 31.

[0032] In this embodiment, as Figure 3 As shown, both ends of the wire feeding wheel 2 are provided with stepped portions 21. The width between the stepped portions 21 at both ends of the wire feeding wheel 2 is adapted to the width of the driven wheel 6. During assembly, the driven wheel 6 is disposed between the stepped portions 21 at both ends, so that when the wire feeding wheel 2 moves axially, the driven wheel 6 is driven to move axially through the stepped portions 21. In this embodiment, as... Figure 2 and Figure 3As shown, several feeding troughs 7 are arranged side by side, and the width of the feeding troughs 7 is different. Specifically, during operation, different feeding troughs 7 are selected according to the different sizes of the bar stock. By operating the handwheel 321, the adjusting screw 32 is rotated, which in turn causes the limiting plate 31 to move. The limiting plate 31 drives the wire feeding wheel 2 to move together, so that the wire feeding wheel 2 and the limiting plate 31 move along the axial direction of the guide rod 33 under the guidance of the guide rod 33. The wire feeding wheel 2 drives the driven wheel 6 to move through the stepped part 21, thereby switching to the appropriate feeding trough 7. In a further preferred embodiment, there are at least two sets of the wire feeding wheel 2 and the driven wheel 6. In this embodiment, as shown... Figure 1 As shown, two sets of wire feeding wheels 2 and driven wheels 6 are provided to make the wire feeding device more stable when conveying long strips of material.

[0033] 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.
