Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, and in particular to a step-by-step copper cladding device for producing copper-aluminum alloy wire. Background Technology

[0002] In modern industrial production, copper-aluminum alloy wires are widely used in fields such as power transmission and electronic equipment manufacturing due to their excellent electrical conductivity, good mechanical strength, and relatively low cost. To further improve the performance of copper-aluminum alloy wires, such as enhancing their conductivity and corrosion resistance, a step-by-step copper cladding process is often used to form composite metal materials that meet diverse industrial needs.

[0003] Existing staged copper cladding equipment for producing copper-aluminum alloy wire typically consists of a feeding mechanism, a cladding mechanism, and a traction mechanism. The feeding mechanism is responsible for conveying the aluminum alloy wire and copper strip to the cladding mechanism. The cladding mechanism uses roller sets and other components to gradually coat the surface of the aluminum alloy wire with copper strip. The traction mechanism pulls the wire to complete the entire cladding process. Its technical principle is mainly to achieve wire conveying and cladding through mechanical transmission.

[0004] However, existing devices have significant drawbacks. On the one hand, the traditional cleaning structure is simple in design and difficult to adapt to the surface cleaning needs of aluminum alloy wires of different specifications and thicknesses, resulting in some aluminum alloy wires having residual impurities on their surface, affecting the quality and efficiency of copper cladding. On the other hand, the roller group spacing adjustment operation is cumbersome and difficult to accurately adapt to the cladding needs of different wires. When facing the production of products with multiple specifications, frequent manual adjustments are not only time-consuming and labor-intensive, but also lead to inaccurate spacing adjustments, reducing cladding efficiency and device flexibility, and failing to meet the high-efficiency and diversified production requirements of modern industry. Therefore, a step-by-step copper cladding device for producing copper-aluminum alloy wires is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a step-by-step copper cladding device for producing copper-aluminum alloy wire, which aims to improve the problem that the cleaning structure in the prior art is difficult to adapt to wires of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A step-by-step copper cladding device for producing copper-aluminum alloy wire includes a base, a support plate fixedly connected to the top of the base, a bracket fixedly connected to the top of the support plate, a cladding component inside the bracket, and a cleaning component on the side of the bracket.

[0008] The cleaning assembly includes multiple fixed boxes. The outer walls of each fixed box are fixedly connected to the inside of the support plate. Electric actuators are fixedly connected to the bottom of the inner walls of each fixed box. Trapezoidal blocks are fixedly connected to the output ends of each electric actuator. Rocker arms are provided on both the left and right sides of each trapezoidal block. The middle section of each rocker arm is rotatably connected to the inside of the fixed box. A wheel is rotatably connected to the bottom of each rocker arm. The side wall of the wheel is slidably connected to the outer wall of the trapezoidal block. A rotating block is rotatably connected to the top of each rocker arm. A clamping plate is fixedly connected to the side wall of the rotating block. Multiple sponge columns are fixedly connected to the inner wall of the clamping plate. The sponge columns are distributed in an array.

[0009] As a further description of the above technical solution:

[0010] The covering component includes multiple fixing blocks and fixing plates. The bottom of each fixing block and fixing plate is fixedly connected to the top of the support plate, and the fixing blocks and fixing plates are distributed in an array.

[0011] As a further description of the above technical solution:

[0012] Guide blocks are fixedly connected to the top left and right sides of the fixed plate. Inside each guide block, there are vertically distributed movable blocks that are slidably connected. A guide wheel is rotatably connected between the side walls of each movable block.

[0013] As a further description of the above technical solution:

[0014] Each guide block is equipped with an adjustment disc at its top, and the bottom of the adjustment disc is rotatably connected to the top of the upper movable block. The adjustment disc is used to adjust the position of the upper movable block.

[0015] As a further description of the above technical solution:

[0016] Each of the fixed blocks has a T-shaped groove on its top, and a T-shaped slider that is symmetrically connected inside the T-shaped groove is rotatably connected to the top of each T-shaped slider.

[0017] As a further description of the above technical solution:

[0018] Multiple positioning grooves are provided on both sides of the inner wall of the T-shaped slide, and the positioning grooves are distributed in an array. Balls are provided on both sides of the inside of the T-shaped slider.

[0019] As a further description of the above technical solution:

[0020] Each ball-holding sidewall is fixedly connected to a limiting plate, and both the limiting plate and the outer wall of the ball-holding are slidably connected inside the T-shaped slider.

[0021] As a further description of the above technical solution:

[0022] Each of the limiting plates is provided with a reset spring. One end of each reset spring is fixedly connected to the side wall of the limiting plate, and the other end of each reset spring is fixedly connected to the inside of the T-shaped slider.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the output end of the electric pusher pulls the trapezoidal block downward, causing the wheel to roll on the outer wall of the trapezoidal block and drive the rocker arm to rotate. The rotation of the rocker arms on both sides drives the top rotating block to move towards the center, thereby causing the sponge column inside the clamping plate to contact the surface of the aluminum alloy wire. This achieves the effect of quickly cleaning the surface of aluminum alloy wires of different thicknesses, solving the problem that traditional cleaning structures are difficult to adapt to wires of different specifications, and improving cleaning efficiency and device applicability.

[0025] 2. In this utility model, the operator manually pulls the second guide wheel, causing its bottom T-shaped slider to slide within the T-shaped groove inside the fixed block. During the sliding, the inner wall of the T-shaped groove squeezes the ball, causing the limiting plate to retract and compressing the reset spring. After the position is confirmed, the reset spring pushes the ball back into the positioning groove, achieving the effect of quickly adjusting the guide wheel spacing. This solves the problem that the traditional roller group spacing adjustment is cumbersome and difficult to accurately adapt to the different wire wrapping requirements, improving the wrapping efficiency and device flexibility.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides one embodiment: a step-by-step copper cladding device for producing copper-aluminum alloy wires uses a base 1 as the basic supporting structure. The base 1 is welded from a 30mm thick Q235B steel plate, and its surface is machined to ensure flatness, serving to stably support the entire device. A support plate 2, made of a 15mm thick Q235B steel plate, is welded and fixed to the top of the base 1. This support plate 2 is used to install components such as the fixing box 4 and provides an installation base for the cladding and cleaning components. A bracket 3, made of rectangular steel pipe, is bolted to the top of the support plate 2. The internal space of the bracket 3 is used to install the cladding components and is the core area for copper cladding of the aluminum alloy wires. The cleaning components are set on the side of the bracket 3 to clean the surface of the aluminum alloy wires, ensuring the quality of the copper cladding.

[0035] The mounting box 4 in the cleaning assembly serves as the basic installation unit. Made of 304 stainless steel through welding, it possesses excellent corrosion resistance and strength. Its outer wall is bolted to pre-drilled mounting holes inside the support plate 2 to accommodate and install other components of the cleaning assembly. An electric actuator 5 is bolted to the bottom of the inner wall of the mounting box 4. The electric actuator 5 is an electric push rod with a high-strength aluminum alloy outer shell. It integrates a motor and a lead screw transmission mechanism to provide power and drive the trapezoidal block 6. This is existing technology and will not be elaborated upon here. The output end of the electric actuator 5 is threadedly connected to the trapezoidal block 6, which is machined from 45# steel and hardened to improve its hardness. Its left and right inclined surfaces cooperate with the rotating wheel 8 to achieve force transmission and motion conversion. The rocker arms 7 on both sides of the trapezoidal block 6 are stamped from Q235B steel plate. The middle section is rotatably connected to the bearing seat inside the fixed box 4 via a pin, serving as a force transmission and motion conversion component. The bottom of the rocker arm 7 is rotatably connected to a rotating wheel 8 via a bearing. The rotating wheel 8 is made of GCr15 bearing steel, and its side wall forms rolling contact with the outer wall of the trapezoidal block 6, which is used to convert the linear motion of the trapezoidal block 6 into the rotation of the rocker arm 7. The top of the rocker arm 7 is rotatably connected to a rotating block 9 via a pin. The rotating block 9 is machined from 45# steel, and the side wall is fixedly connected to a clamping plate 10 by welding, which is used to drive the clamping plate 10 to move. The clamping plate 10 is stamped from 304 stainless steel, and multiple sponge columns 11 are fixedly connected to the inner wall by adhesive. The sponge columns 11 are distributed in an array and are made of high-density polyurethane sponge, which has good adsorption and flexibility, and is used to wipe and clean dust, oil and other impurities on the surface of the aluminum alloy wire.

[0036] Reference Figure 4 and Figure 5The cladding assembly, as the core structural unit for producing copper-aluminum alloy wire, consists of a basic support frame formed by multiple fixed blocks 12 and fixed plates 13. Both fixed blocks 12 and fixed plates 13 are made of high-strength 45# steel, and their bottoms are fixedly connected to the top of the support plate 2 via bolts to ensure structural stability during the cladding process. They are arranged in an array, providing a mounting base for the guide wheels and adjustment mechanisms. Fixed blocks 12 are mainly used to install guide wheels 20 and the adjustment assembly, while fixed plates 13 serve the installation and adjustment of guide wheels 17. Guide blocks 15 are welded to the left and right sides of the top of the fixed plates 13. The guide blocks 15 are made of 304 stainless steel, with precision-machined vertically penetrating guide grooves inside for installing moving blocks 16. Each guide block 15 has a slidingly connected vertically distributed moving block 16 inside. The moving blocks 16 are made of wear-resistant QT400-15 ductile iron, with ground sidewalls that form a clearance fit with the guide grooves inside the guide blocks 15, ensuring smooth movement and precise positioning. A guide wheel 17 is rotatably connected between the side walls of the movable block 16 via bearings. The guide wheel 17 is made of GCr15 bearing steel, with a surface hardened to HRC60-62. Its rim is arc-shaped and used to guide the wrapping path of copper strips and aluminum alloy wires. An adjusting disc 18, located on top of the guide block 15, is machined from 45# steel by turning and milling. Its bottom is connected to the top of the upper movable block 16 via a thrust ball bearing and can rotate around a vertical axis. The adjusting disc 18 has graduations and adjusting threads on its surface. By rotating the adjusting disc 18, the upper movable block 16 can be driven to move up and down along the guide groove of the guide block 15, achieving precise adjustment of the vertical position of the guide wheel 17 to accommodate copper strips and aluminum alloy wires of different specifications. A T-shaped groove 14 is milled into the top of the fixed block 12, which is used to install a T-shaped slider 19. The T-shaped slider 19 is made of 42CrMo alloy steel, and its hardness reaches HRC35-40 after quenching and tempering. A guide wheel 20 is rotatably connected to its top via a deep groove ball bearing. The guide wheel 20 has the same structure as the guide wheel 17 and is used to cooperate with the guide wheel 17 to form a covering channel. Multiple positioning grooves 21 are drilled on both sides of the inner wall of the T-shaped slide groove 14. These positioning grooves 21 are distributed in an array and are used to cooperate with the retaining ball 24 to achieve positioning and locking of the T-shaped slider 19. The inner sides of the T-shaped slider 19 are provided with retaining ball 24 mounting cavities through milling and drilling processes. The retaining ball 24 is made of GCr15 bearing steel, has a diameter of 8mm, and a surface hardness of HRC60-62. It is used to engage with the positioning grooves 21 to fix the T-shaped slider 19. Each ball 24 is fixedly connected to a limiting plate 23 by welding. The limiting plate 23 is made of stainless steel 304 and is 2mm thick. The limiting plate 23 and the outer wall of the ball 24 form a sliding fit with the guide groove inside the T-shaped slider 19 to ensure that the ball 24 moves in an accurate direction.A reset spring 22 is provided on the side of the limiting plate 23. The reset spring 22 is made of 65Mn spring steel with a wire diameter of 1.5mm. After heat treatment, the elastic coefficient is stable. One end is fixed to the side wall of the limiting plate 23 by welding, and the other end is welded to the spring seat preset inside the T-shaped slider 19 to provide reset force for the ball 24.

[0037] Working principle: When using this step-by-step copper cladding device for producing copper-aluminum alloy wire, the feeding device first feeds one end of the aluminum alloy wire into the clamping plates 10 above the fixed box 4. Then, the output end of the electric pusher 5 at the bottom of the fixed box 4 pulls the trapezoidal block 6 downward. The displacement of the trapezoidal block 6 causes the rotating wheel 8 to roll on the outer wall of the trapezoidal block 6, and drives the rocker arm 7 to rotate. The rotation of the rocker arms 7 on both sides then drives the rotating block 9 at the top to move towards the center. The displacement of the rotating block 9 drives the clamping plate 10 to move towards the center as well, so that the sponge column 11 inside contacts the surface of the aluminum alloy wire and cleans its surface. When encountering aluminum alloy wires of different thicknesses, the electric pusher 5 drives the trapezoidal block 6 to move, which can achieve the effect of quickly cleaning the surface of aluminum alloy wires of different thicknesses.

[0038] After the aluminum alloy wire is cleaned, it continues to penetrate between the guide wheels 20 on one side of the top of the fixed block 12. At the same time, the feeding device feeds the copper strip under the aluminum alloy wire. Under the action of the roller group composed of multiple guide wheels 17 and guide wheels 20 with progressively smaller gaps, it is gradually wrapped. When it is necessary to adjust the spacing of the guide wheels 20, the worker manually pulls the guide wheels 20, causing the T-shaped slider 19 at its bottom to slide in the T-shaped groove 14 inside the fixed block 12. When the T-shaped slider 19 moves, the inner wall of the T-shaped groove 14 squeezes the retaining balls 24 on both sides of the T-shaped slider 19, causing the retaining balls 24 to drive the limiting plate 23 back into the T-shaped slider 19, and simultaneously squeeze the return spring 22. When the position is confirmed, the return spring 22 pushes the limiting plate 23 and retaining balls 24 out, and the retaining balls 24 are locked into the positioning groove 21 on the inner wall of the T-shaped groove 14, thus achieving the effect of quickly adjusting the spacing of the roller group.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
