Description

Technical Field

[0001] This utility model relates to the field of copper alloy wire processing technology, specifically to a guide roller for copper alloy wire stretching operations. Background Technology

[0002] In the manufacturing process of copper alloy wire, the stretching and forming process is a key step. It is mainly used to stretch and reduce the diameter of the copper alloy wire using dies to achieve the required diameter and strength. This process requires a series of stretching operations through continuously set stretching dies to achieve the expected diameter and shape, and obtain the corresponding mechanical properties.

[0003] In the drawing and forming process of copper alloy wire, the copper alloy wire blank is typically drawn multiple times through dies of different apertures to gradually reduce the wire diameter. During this process, the guiding structure plays a crucial role, guiding the copper alloy wire along a predetermined path and preventing problems such as deviation and entanglement during drawing. This ensures the stability and accuracy of the drawing process, thereby guaranteeing that the produced copper alloy wire meets the required quality standards. However, existing guiding structures used in copper alloy wire drawing operations have several shortcomings:

[0004] Firstly, existing material guiding structures are generally quite simple, mostly only capable of guiding single wires. In actual production, to improve production efficiency, it is often necessary to stretch multiple copper alloy wires simultaneously, and this single-wire guiding structure obviously cannot meet the needs of high-efficiency production.

[0005] Secondly, the existing material guiding structure has poor adaptability. Different specifications and materials of copper alloy wires require different levels of friction and guiding accuracy from the guiding structure during the stretching process. However, the existing guiding structure cannot be flexibly adjusted to meet these different needs. This results in either surface damage due to improper friction or substandard dimensional accuracy after stretching due to insufficient guiding accuracy. These problems not only affect the production quality of copper alloy wires but also reduce production efficiency and increase production costs.

[0006] Therefore, it is urgent to develop a more reasonable material guiding structure that can meet the needs of multi-wire material guiding and has good adaptability for copper alloy wire drawing operations, so as to solve the shortcomings of existing technologies and improve the overall level of copper alloy wire drawing operations. Utility Model Content

[0007] The technical problem solved by this utility model is to provide a guide roller for copper alloy wire stretching operations, which can solve the defects in the above-mentioned technical background.

[0008] The technical problem solved by this utility model is achieved by the following technical solution:

[0009] A guide roller for copper alloy wire stretching operations includes a roller frame and a guide roller assembly disposed on the roller frame;

[0010] The guide roller assemblies are arranged in groups on the roller frame along the stretching direction of the copper alloy wire. Each group of guide roller assemblies includes two oppositely arranged and independently rotatable roller shafts, which are perpendicular to the stretching direction of the copper alloy wire. The roller shafts are fixedly assembled to the roller frame on one side by a fixed side guard, and a movable side guard is detachably assembled on the other side. Multiple cylindrical structural blocks are fixedly assembled on the roller shafts, and the movable side guards press and fix the cylindrical structural blocks at their ends on the outside. The outer cylindrical surface of each cylindrical structural block is formed with circumferentially arranged wire grooves. The cylindrical structural blocks are arranged one-to-one on the two roller shafts, so that the wire grooves on the opposite cylindrical structural blocks together form a wire channel for the copper alloy wire to pass through.

[0011] As a further limitation, the roller frame is equipped with bearing seats at both ends of the roller shaft.

[0012] As a further limitation, the roller frame is a U-shaped structural support; the roller frame has matching fixed assembly parts and movable assembly parts formed on the vertical sides of both sides respectively; the grouped guide roller assemblies are assembled on the corresponding fixed assembly parts or movable assembly parts through the fixed side blocks and movable side blocks on both sides; and the roller shaft assembled on the movable assembly part can be adjusted in distance relative to the other roller shaft assembled on the fixed assembly part.

[0013] The roller shaft of the fixed assembly extends outward from the roller frame and is connected to an external drive motor as a power source;

[0014] The movable assembly includes a waist-shaped hole and a slide seat mounted at the waist-shaped hole position. The slide seat has a roller shaft assembly part for assembling the roller shaft on the front side, and an adjustable pressure block with fasteners is connected to the back side.

[0015] As a further limitation, the movable side guard is detachably assembled on the roller shaft via a detachable assembly structure, wherein the detachable assembly structure is one or a combination of threaded structure, pin structure, snap-fit ​​structure, and magnetic structure.

[0016] As a further limitation, the cylindrical structural block is formed with matching positioning protrusions and positioning grooves on its top and bottom surfaces; the fixed side block and the movable side block are also formed with matching positioning protrusions and positioning grooves on their inner surfaces, so that adjacent cylindrical structural blocks, as well as cylindrical structural blocks and fixed side blocks and movable side blocks, can be accurately positioned and press-fitted.

[0017] The cross-section of the positioning protrusion is a regular polygon, preferably an equilateral triangle, a square, or a regular hexagon.

[0018] As a further limitation, the cylindrical structural block is a replaceable structure, and different cylindrical structural blocks are used in pairs, with wire grooves having different cross-sectional dimensions and shapes.

[0019] As a further limitation, the cylindrical structural block is made of wear-resistant alloy steel and is coated with a wear-resistant coating on the surface of the corresponding wire groove area to improve its service life and wear resistance.

[0020] Beneficial Effects: The guide roller of this utility model for copper alloy wire drawing, by adopting the above-mentioned technical solution, enables the guide structure to simultaneously meet the operational requirements of multi-wire drawing, significantly improving production efficiency. During multi-wire drawing operations, this component ensures stability and precision, effectively avoiding problems such as wire misalignment and entanglement during the drawing process. Furthermore, by adjusting the roller position of the movable assembly and replacing the cylindrical structural blocks equipped with wire grooves of different cross-sectional sizes and shapes, this component can flexibly adapt to drawing operations of copper alloy wires of different specifications and materials, further enhancing its practicality and flexibility.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] See Figure 1 A preferred embodiment of a guide roller for copper alloy wire stretching operations is provided. In this embodiment, the guide roller can be used to simultaneously stretch up to four copper alloy wires 13. For ease of description, only the guiding state of the copper alloy wire 13 in the middle position is shown.

[0025] The guide tube of this embodiment includes a roller frame and a guide roller assembly disposed on the roller frame. The roller frame is U-shaped in general, including a roller frame body 5 with an L-shaped cross-section on the left and an outer roller frame stop 7 with an inverted L-shaped cross-section on the right. The roller frame body 5 is provided with a guide rail 6 on the lower surface of the horizontal plane, while the outer roller frame stop 7 is formed with a groove on the upper surface of the horizontal plane that matches the guide rail 6. Through the combination of the groove and the guide rail 6, the outer roller frame stop 7 can be pulled outward to assemble the guide roller assembly, and after assembly, it can be pushed in and fixed with a locking nut 8 to ensure the stability of the overall structure.

[0026] In another embodiment, the guide roller assembly can also adopt other rod assembly methods in the prior art on the roller frame, such as notched ring buckles, snap buckles, pins, etc.

[0027] The bottom of the roller frame body 5 is provided with an external assembly part 4. Through the external assembly part 4, the entire roller frame body 5 and the guide roller assembly mounted on the roller frame body 5 can be fixedly mounted to external equipment such as a machine frame. The guide roller has the stretching direction of the copper alloy wire in the view-in-paper direction. The roller frame is provided with multiple sets of guide roller assemblies at intervals in this stretching direction to clamp the copper alloy wire and guide it to move along a predetermined path to ensure the stability and smoothness of the roller rotation.

[0028] Figure 1 This illustration shows an embodiment of the structural design of one set of guide roller assemblies. In this embodiment, a fixed assembly part 3 is provided on the roller frame body 5 and the outer roller frame stop 7 at corresponding positions on both sides of the lower vertical edge of the roller frame. The position of the fixed assembly part 3 on the roller frame body 5 / outer roller frame stop 7 is fixed and cannot be adjusted. A movable assembly part 17 is provided on the roller frame body 5 and the outer roller frame stop 7 at corresponding positions on both sides of the lower vertical edge of the roller frame. The position of the movable assembly part 17 on the roller frame body 5 / outer roller frame stop 7 is adjustable.

[0029] Specifically, the movable assembly 17 includes a slotted hole and a slide seat mounted at the slotted hole. The slide seat has a roller mounting section for mounting the roller on the side facing the roller shaft, while an adjustable pressure block with fasteners is connected to the side facing away from the roller shaft. By loosening the adjustable pressure block, the position of the slide seat within the slotted hole can be adjusted. After adjusting to the selected position, tightening the adjustable pressure block fixes the slide seat and the roller shaft mounted on it in the selected position. By adjusting the position of the movable assembly 17, the distance between the two roller shafts in the corresponding guide roller assembly can be adjusted, thereby adapting to the requirements of stretching copper alloy wires of different diameters.

[0030] Both the fixed assembly part 3 and the movable assembly part 17 are equipped with guide roller assembly units. The guide roller assembly unit on the fixed assembly part 3 is an active structure, driven by a drive motor 1 located on the outer side of the vertical side of the roller frame body 5. The guide roller assembly unit on the movable assembly part 17 is a driven structure, rotating through the friction between the roller body and the copper alloy wire. The active and driven guide roller assembly units together constitute the complete guide roller assembly.

[0031] The guide roller assembly unit includes a roller shaft 15, the left side of which is closed by a fixed side guard 16. A cylindrical structural block 12 is fixedly mounted on the roller shaft 15 along its length. There are four cylindrical structural blocks 12 in the guide roller assembly unit that are mounted on the fixed assembly part 3 as the active structure and four cylindrical structural blocks 12 that are mounted on the movable assembly part 17 as the driven structure. Their size, structure and assembly position are in one-to-one correspondence. The rightmost cylindrical structural block 12 of the roller shaft 15 is detachably assembled at the outer end of the roller shaft 15 through the detachable assembly structure of the movable side guard 10. The assembled movable side guard 10 is pressed against the outer surface of the rightmost cylindrical structural block 12 to complete the pre-assembly of the structure. Under the pre-assembly condition, the roller shaft 15 extends from the cylindrical structural blocks 12 on both sides.

[0032] In the pre-assembled state of the two guide roller assembly units, during assembly, the roller shaft 15 extending from the left is first connected to the coupling 2 and the fixed bearing seat 18 respectively. Then, with the outer side stop 7 of the roller frame pressed into place, the right side extension of the roller shaft 15 is locked and assembled using the locking bearing seat 9 to ensure the stability and smoothness of its rotation.

[0033] To ensure precise positioning and press-fitting between adjacent cylindrical structural blocks 12, and between cylindrical structural blocks 12 and fixed side blocks 16 and movable side blocks 10, the cylindrical structural blocks 12 have matching positioning protrusions 14 and positioning grooves formed on their top and bottom surfaces. Similarly, the fixed side blocks 16 and movable side blocks 10 have matching positioning protrusions 14 and positioning grooves formed on their inner surfaces. The cross-section of the positioning protrusions 14 is a regular polygon, such as an equilateral triangle, square, or regular hexagon, to ensure the accuracy and stability of positioning.

[0034] The roller shaft 15 of the fixed assembly 3 is connected to the drive motor 1 via the coupling 2 to serve as a power source to drive the entire guide roller assembly to rotate.

[0035] The outer cylindrical surface of the cylindrical structural block 12 is formed with a circumferentially arranged wire groove 11 for the copper alloy wire 13 to pass through. In order to ensure that the copper alloy wire can move stably along the predetermined path during the stretching process, the cross-sectional dimensions and shape of the wire groove 11 need to match the specifications of the copper alloy wire.

[0036] In this embodiment, the cylindrical structural block 12 is a replaceable structure. Depending on the specifications of the copper alloy wire, cylindrical structural blocks 12 with different cross-sectional dimensions and shapes of the wire groove 11 can be selected for replacement, thereby meeting different production needs. Furthermore, to improve the service life and wear resistance of the cylindrical structural block 12, it is made of wear-resistant alloy steel and coated with a wear-resistant coating on the surface of the corresponding wire groove 11 area.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
