Description

Technical Field

[0001] This utility model relates to the technical field of billet pulling equipment, and in particular to a traction device for SCR continuous casting copper billets. Background Technology

[0002] SCR continuous casting, as the mainstream technology for producing electrical copper rods, occupies a core position in the copper and copper alloy processing industry due to its high production efficiency, stable product quality, and excellent conductivity. However, existing SCR continuous casting copper billet traction devices suffer from insufficient clamping stability in practical applications, easily causing damage to the copper billet or traction slippage. Traditional traction devices mostly adopt a conveyor wheel extrusion conveying structure, with point or line contact between the conveyor wheel and the copper billet. The small contact area leads to high local pressure on the surface of the copper billet, easily causing defects such as surface deformation and scratches. At the same time, insufficient friction easily leads to slippage, affecting the continuity of traction. Furthermore, the clamping accuracy and traction synchronization are poor, and the adaptability is insufficient. When the copper billet is output from the crystallizer, it has a fixed movement speed and posture. Existing traction devices lack precise positioning and follow-up adjustment mechanisms, making it difficult to quickly respond to changes in the position of the copper billet, resulting in a high clamping alignment error rate.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Reference Figures 1-3 This embodiment provides a traction device for SCR continuous casting copper billets, comprising: Main support 1, which is supported and installed on the ground; The traction seat 11 is fixedly installed on the main support 1, and a drive assembly is provided in the traction seat 11. The clamping mechanism 2 is horizontally slidably mounted on the traction seat 11 and is used to clamp the copper billet. It is driven to slide by the drive assembly. The clamping mechanism 2 includes: The traction carriage 21 is slidably mounted on the traction seat 11 and is driven by the drive assembly; The clamping frame 22 is connected to the traction slide 21, and two inclined sliding plates 23 are symmetrically arranged inside the clamping frame 22. A clamping cylinder 24 is installed in the traction slide 21. A transmission plate 25 is provided at the output end of the clamping cylinder 24. Two hinge rods 26 are symmetrically swinging on the transmission plate 25. Two clamping blocks 27 are respectively oscillatingly mounted on two hinged rods 26, and the clamping blocks 27 slide in cooperation with the corresponding inclined top slide plate 23; In this embodiment, the clamping cylinder 24, located in the traction carriage 21, is activated, and its output end pushes the transmission plate 25 forward. The movement of the transmission plate 25 causes the two hinge rods 26 to swing around their swing points. The swinging of the hinge rods 26 causes the clamping blocks 27 to move along the inclined plane trajectory of the inclined slide plate 23 under the constraint and guidance of the inclined slide plate 23. The two clamping blocks 27 gradually move closer to the middle, thereby clamping the copper billet. During the clamping process, the clamping blocks 27 can provide a more uniform clamping force, increase the contact area, and reduce the local pressure on the surface of the copper billet. After the clamping mechanism 2 clamps the copper billet through the clamping blocks 27, the drive assembly continues to work, driving the traction carriage 21. The copper billet slides on the traction seat 11, thereby driving the entire clamping mechanism 2 and the clamped copper billet to move at a predetermined speed and rhythm, continuously pulling the copper billet out of the crystallizer. In the clamping mechanism 2 of this device, the clamping block 27, under the synergistic action of the clamping cylinder 24, transmission plate 25, hinge rod 26 and inclined slide plate 23, can provide a more uniform clamping force, reduce the local pressure on the surface of the copper billet, reduce the occurrence of surface deformation and scratches, and improve the surface quality of the copper billet. This device can generate greater friction, thereby effectively avoiding slippage due to insufficient friction during the traction process, ensuring the continuity of traction and improving production efficiency.

[0017] As a preferred embodiment of the above technical solution, the clamping end of the clamping block 27 is provided with teeth; In this embodiment, the teeth on the clamping end of the clamping block 27 can be embedded into the surface of the copper billet, increasing the connection strength and stability between the clamping block 27 and the copper billet, and reducing production accidents caused by unstable clamping. After the teeth are embedded into the surface of the copper billet, the friction between the clamping block 27 and the copper billet is increased. During the traction process, the greater friction can better overcome the various resistances encountered by the copper billet, thereby effectively avoiding traction slippage caused by insufficient friction and ensuring the continuity of traction.

[0018] Specifically, such as Figures 2 to 3 As shown, the clamping mechanism 2 also includes: The cylinder bearing seat 2a is fixedly installed in the traction slide 21, and the clamping cylinder 24 is rotatably mounted in the traction slide 21 via the cylinder bearing seat 2a. Driven gear 2b is fixedly mounted on clamping frame 22. Clamping frame 22 is rotatably mounted on traction slide 21. The output rod of clamping cylinder 24 is slidably inserted into driven gear 2b and clamping frame 22. A rotary motor 2c is fixedly mounted on the traction slide 21. The output end of the rotary motor 2c is provided with a drive gear 2d, which meshes with the driven gear 2b. In this embodiment, after the copper billet is output from the crystallizer, because the copper billet has a fixed speed and posture during output, the existing traction device has difficulty responding quickly to its position change. At this time, the rotary motor 2c starts, and its output end drives the drive gear 2d to rotate. Because the drive gear 2d meshes with the driven gear disk 2b, the driven gear disk 2b will rotate with the rotation of the drive gear 2d. Since the driven gear disk 2b is fixedly mounted on the clamping frame 22, and the clamping frame 22 is rotatably mounted on the traction slide 21, the clamping frame 22 will follow the movement of the driven gear 2d. The driven gear plate 2b rotates together with the driven gear plate 2b. At the same time, the clamping cylinder 24 is rotatably mounted in the traction slide 21 through the cylinder bearing seat 2a. Its output rod is slidably inserted into the driven gear plate 2b and the clamping frame 22. During the rotation of the clamping frame 22, the clamping cylinder 24 can rotate a certain angle relative to the traction slide 21 to adapt to the rotation of the clamping frame 22, thereby driving the entire clamping mechanism 2 to adjust the angle, so that the clamping block 27 can be quickly aligned with the copper billet and achieve precise positioning, thereby improving the clamping accuracy.

[0019] More specifically, such as Figures 1 to 2 As shown, the driving component includes: Two slide rails 12 are symmetrically arranged inside the traction seat 11; The slide 13 is slidably mounted on the traction seat 11 and is fixedly connected to the traction slide 21. Two sliders 14 are symmetrically arranged on the slide 13, and the two sliders 14 are slidably engaged with the two slide rails 12 respectively. The threaded slider 15 is fixedly installed at the bottom of the slide block 13. A drive screw is rotatably provided in the traction seat 11. The drive screw is driven by a motor. The threaded slider 15 is threadedly engaged with the drive screw. In this embodiment, the motor drives the drive screw to rotate in the traction seat 11. When the drive screw rotates, the threaded slider 15 will generate linear motion along the axial direction of the drive screw. The linear motion of the threaded slider 15 will cause the slide block 13 to slide on the traction seat 11. The slide rail 12 provides precise guidance for the sliding of the slide block 13, ensuring that the slide block 13 can only move linearly along the direction of the slide rail 12 without deviation or shaking. Since the slide block 13 is fixedly connected to the traction slide 21, the sliding of the slide block 13 will cause the traction slide 21 to slide horizontally together. The traction slide 21 will drive the copper billet to slide together, continuously and stably pulling the copper billet out of the crystallizer and conveying it to the subsequent process at a predetermined speed and direction. The drive assembly adopts the cooperation of the slide rail 12 and the slider 14 to provide precise guidance for the sliding of the slide block 13. The cooperation of the slide rail 12 and the slider 14 can effectively reduce the deviation and shaking of the slide block 13 during the sliding process, ensuring that the slide block 13 can only move linearly along the predetermined direction, thereby improving the motion accuracy of the entire traction device.

[0020] Furthermore, such as Figure 2 As shown, two support rollers 28 are rotatably mounted on the traction carriage 21, and both support rollers 28 roll in contact with the top surface of the traction seat 11. In this embodiment, the sliding friction between the traction carriage 21 and the top surface of the traction seat 11 is transformed into rolling friction, which can reduce the frictional resistance during the movement, thereby reducing the energy consumption of the motor and improving energy utilization efficiency. At the same time, it also reduces the heat generated by friction, which helps to extend the service life of the device.

[0021] Furthermore, a noise-reducing rubber sleeve is provided on the outer circumference of the support roller 28; In this embodiment, the noise-reducing rubber sleeve has good elasticity and sound absorption properties. When the support roller 28 rolls, the noise-reducing rubber sleeve can absorb and buffer some of the vibration energy generated by rolling friction, thereby effectively reducing the noise generated during the rolling process, thus improving the working environment and reducing the impact of noise on operators.

[0022] Furthermore, such as Figure 1 As shown, a guide bracket 16 is provided on the traction seat 11, and a guide roller 17 is rotatably mounted on the guide bracket 16; In this embodiment, the guide roller 17 can provide a clear guiding path for the copper billet, so that the copper billet is in the correct position and posture before entering the clamping mechanism 2, thereby reducing the clamping alignment error rate caused by the position deviation of the copper billet; the guide roller 17 enables the copper billet to achieve a smooth transition from the output of the crystallizer to the clamping of the clamping mechanism.

[0023] Furthermore, a protective sleeve is provided on the guide roller 17; In this embodiment, the protective sleeve is usually made of a soft material with a certain degree of wear resistance. When the copper billet comes into contact with the guide roller 17, the protective sleeve can prevent the copper billet from directly rubbing against the hard surface of the guide roller 17, thereby reducing the possibility of scratches, wear and other defects on the surface of the copper billet. The elasticity of the protective sleeve can play a role in buffering and shock absorption, absorbing some vibration energy, reducing the noise generated by vibration, thereby improving the working environment and reducing the harm of noise to operators.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
