Description

Technical Field

[0001] This utility model belongs to the field of wire technology, and more specifically, it relates to a curved guide tube structure at the inlet of a wire spinning machine. Background Technology

[0002] Currently, the wire feeding rollers of high-speed wire rod production lines use curved guide tubes made of cast steel to feed the wire. When the wire passes through the curved guide tube, it will rub against the outlet end of the curved guide tube, which will easily cause the guide tube to be scrapped due to wear. At the same time, the wire will also experience friction and wear. Due to the friction of the wire, the surface of the finished coiled wire will have scratches, abrasions and other quality problems, which will affect the quality.

[0003] Existing technology includes a device entitled "A Front Guide Groove Device for a Double-Tube Wire Spinner" with publication number CN217912187U. This technology relates to a front guide groove device for a double-tube wire spinner, belonging to the field of rolling mill equipment technology. To address the inconvenience of replacing the wire spinner tube, it includes an air-blowing guide tube, a straight guide tube, and a bent guide tube. The centers of the air-blowing guide tube, the straight guide tube, and the bent guide tube are all located on the same axis and are internally connected. A connecting part is provided at the end of the straight guide tube near the bent guide tube, and a connecting groove is provided on the connecting part for inserting the bent guide tube. The bent guide tube is inserted into the connecting groove. A fastening component for fixing the bent guide tube is provided on the side wall of the connecting part. A bending guide groove is provided inside the bent guide tube, and the bending guide groove is bent towards the direction of the wire spinner tube. This application has the effect of reducing labor intensity and facilitating replacement. However, this technology does not address the technical problem and solution of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is: to address the shortcomings of the existing technology by providing a simple structure that can effectively solve the problem of damage to the curved guide tube and scratches on the surface of the wire caused by friction between the wire and the outlet end of the curved guide tube, improve the service life of the guide tube, improve the surface quality of the wire, and at the same time, the simple structure makes it easy to maintain and replace. The increased service life of the curved guide tube can reduce downtime and save costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model relates to an inlet curved guide tube structure for a wire spinning machine, comprising a curved guide tube, an anti-scratch guide wheel, and a connector. The inlet end of the curved guide tube is close to the pinch roller assembly, and the upper part of the outlet end of the curved guide tube is provided with a connector. The connector is connected to the anti-scratch guide wheel, which is a movable rotating wheel.

[0007] One end of the wire enters the bending guide tube through the pinch roller group and then passes around the anti-scratch guide wheel, while the other end of the wire enters the wire spinning machine.

[0008] The thickness of the anti-scratch guide wheel is consistent with the outer diameter of the curved conduit, and the maximum width of the arc-shaped guide surface of the anti-scratch guide wheel is consistent with the inner diameter of the curved conduit.

[0009] The inner diameter of the curved conduit is larger than the diameter of the wire.

[0010] Water cooling pipe nozzles are installed near the scratch-resistant guide wheel.

[0011] The scratch-resistant guide wheel is made of wear-resistant stainless steel.

[0012] The anti-scratch guide wheel is located directly above the outlet end of the curved guide tube.

[0013] The lowest point of the anti-scratch guide wheel is more than 1 mm higher than the highest point of the outlet end of the curved guide tube, and the side of the anti-scratch guide wheel closest to the curved guide tube is more than 10 cm away from the outlet end of the curved guide tube.

[0014] The anti-scratch guide wheel includes a guide wheel seat and a guide wheel body. A curved guide tube is welded to a connecting piece, and the guide wheel seat is welded to the connecting piece. The guide wheel body is movably connected to the guide wheel seat.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The wire spinning machine inlet curved guide tube structure of this utility model features a curved guide tube with its inlet end close to the pinch roller assembly. The pinch roller assembly releases the wire and applies a certain force to the wire to ensure it remains taut during transport, preventing it from slack and contacting the inner wall of the curved guide tube. After passing through the curved guide tube, the wire is released from its outlet end. A connector is fixedly mounted on the outside of the outlet end of the curved guide tube, and an anti-scratch guide wheel is fixedly connected to the connector. This anti-scratch guide wheel is designed to rotate flexibly. The wire released from the outlet end of the curved guide tube bypasses the anti-scratch guide wheel and does not directly contact the outlet end of the curved guide tube. This prevents friction damage to the curved guide tube and avoids surface damage due to friction, ensuring the processing quality of the wire. After bypassing the anti-scratch guide wheel, the wire is fed into the wire spinning machine, which spins the wire into coils for collection, storage, and transfer. Attached Figure Description

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0023] As attached Figure 1 - Appendix Figure 3 As shown, this utility model is an inlet curved guide tube structure for a wire feeding machine, including a curved guide tube 1, an anti-scratch guide wheel 2, and a connector 3. The inlet end of the curved guide tube 1 is close to the pinch roller group 4, and the connector 3 is provided on the upper part of the outlet end of the curved guide tube 1. The connector 3 is connected to the anti-scratch guide wheel 2, which is a movable rotating wheel. This structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structure setting, a curved guide tube 1 is provided, with its inlet end close to the pinch roller group 4. The pinch roller group 4 is used to release the wire 5, and it applies a certain force to the wire 5 to ensure that the wire 5 is in a taut state during the conveying process, preventing the wire 5 from slack and contacting the inner wall of the curved guide tube 1. After passing through the curved guide tube 1, the wire 5 is released from the outlet end of the curved guide tube 1. The connector 3 is fixedly set on the outer part of the outlet end of the curved guide tube 1, and the anti-scratch guide wheel 2 is fixedly connected to the connector 3. The anti-scratch guide wheel 2 is a flexible rotating structure. The wire 5, released from the outlet end of the curved guide tube 1, passes over the anti-scratch guide wheel 2 and does not directly contact the outlet end of the curved guide tube 1. This prevents friction damage to the curved guide tube 1 and ensures the processing quality of the wire 5. After passing over the anti-scratch guide wheel 2, the wire 5 is fed into the wire spinning machine 6, which spins the wire 5 into coils for collection, storage, and transfer. The curved guide tube structure at the inlet of the wire spinning machine described in this invention is simple in structure and effectively solves the problem of damage to the curved guide tube and scratches on the wire surface caused by friction between the wire and the outlet end of the curved guide tube. It improves the service life of the curved guide tube and the surface quality of the wire. Furthermore, its simple structure facilitates maintenance and replacement, and the increased service life of the curved guide tube reduces downtime and saves costs.

[0024] One end of wire 5 enters the curved guide tube 1 through the pinch roller group 4 and then passes around the anti-scratch guide wheel 2, while the other end of wire 5 enters wire 6. In the above structure, the anti-scratch guide wheel 2 is mainly used to guide the wire and prevent the wire 5 from contacting the curved guide tube 1. The anti-scratch guide wheel 2 is a flexible rotating structure that can transport the wire 5 by rolling.

[0025] The thickness of the anti-scratch guide wheel 2 is the same as the outer diameter of the curved conduit 1, and the maximum width of the arc-shaped guide surface 9 of the anti-scratch guide wheel 2 is the same as the inner diameter of the curved conduit 1. With this structure, the arc-shaped guide surface 9 of the anti-scratch guide wheel 2 reliably accommodates and guides the wire, preventing the wire from detaching from the guide wheel.

[0026] The inner diameter of the curved conduit 1 is larger than the diameter of the wire 5. With this structure, the wire is in a taut state when passing through the curved conduit 1, and the wire will not contact the inner wall of the curved conduit, thus avoiding friction.

[0027] A water cooling pipe nozzle 10 is installed near the anti-scratch guide wheel 2. In the above structure, the water cooling pipe nozzle 10 is used to spray cooling water to reliably cool the anti-scratch guide wheel 2.

[0028] The scratch-resistant guide wheel 2 is made of wear-resistant stainless steel. This structure ensures that the scratch-resistant guide wheel 2 meets the required strength and can be used for a long time.

[0029] The anti-scratch guide wheel 2 is located directly above the outlet end of the curved conduit 1. In this structure, after the wire 5 passes through the anti-scratch curved conduit 1, it moves forward along the bottom of the arc-shaped guide surface 9 of the anti-scratch guide wheel, changing the sliding friction between the wire and the curved conduit 1 into rolling friction between the wire and the anti-scratch guide wheel 2, thus reducing conduit wear and wire surface scratches caused by sliding friction.

[0030] The lowest point of the anti-scratch guide wheel 2 is at least 5 mm higher than the highest point of the outlet end of the curved conduit 1, and the side of the anti-scratch guide wheel 2 closest to the curved conduit 1 is at least 10 cm away from the outlet end of the curved conduit 1. This structure controls the relative position of the anti-scratch guide wheel 2 to the curved conduit, ensuring that the wire does not come into contact with the curved conduit and rub against it.

[0031] The anti-scratch guide wheel 2 includes a guide wheel seat 7 and a guide wheel body 8. A connecting piece 3 is welded to the curved guide tube 1, and the guide wheel seat 7 is welded to the connecting piece 3. The guide wheel body 8 is movably connected to the guide wheel seat 7. In this structure, the guide wheel seat is reliably connected to the connecting piece, the guide wheel body is movably connected to the guide wheel seat, and the guide wheel body 8 can rotate flexibly to guide the wire 5.

[0032] The wire drawing machine inlet bending guide structure described in this utility model has a reasonable structural design. An anti-scratch guide wheel 2 is added above the outlet of the bending guide 1. During wire production, the wire 5 travels along the bottom of the guide wheel, avoiding contact with the outlet end of the bending guide 1. This changes sliding friction to rolling friction, reducing scratches and abrasions on the wire and improving the quality of the coiled product. Simultaneously, it reduces the wear cycle of the bending guide 1. Before implementation, a single bending guide 1 would wear through after 3000-4000 tons of steel. After implementation, with steel throughput exceeding 20,000 tons, production can continue by simply replacing the anti-scratch guide wheel, reducing costs and improving production continuity. Furthermore, this utility model has a simple structure and low improvement costs.

[0033] The wire feeding machine inlet curved guide structure of this utility model includes a curved guide 1 with its inlet end close to the pinch roller group 4. The pinch roller group 4 is used to release the wire 5 and applies a certain force to the wire 5 to ensure that the wire 5 is in a taut state during the conveying process, preventing the wire 5 from slack and contacting the inner wall of the curved guide 1. After passing through the curved guide 1, the wire 5 is released from the outlet end of the curved guide 1. A connector 3 is fixedly installed on the outer part of the outlet end of the curved guide 1, and an anti-scratch guide wheel 2 is fixedly connected to the connector 3. The anti-scratch guide wheel 2 has a flexible rotating structure. After the wire 5 is released from the outlet end of the curved guide 1 and passes around the anti-scratch guide wheel 2, it will not directly contact the outlet end of the curved guide 1. On the one hand, the wire 5 will not contact the curved guide 1, thus avoiding friction damage to the curved guide 1. On the other hand, the surface of the wire 5 will not be damaged due to friction, ensuring the processing quality of the wire 5. After passing over the anti-scratch guide roller 2, the wire 5 is fed into the wire spinning machine 6, which is used to spin the wire 5 into coils for collection, storage and transfer.

[0034] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
