Description

Technical Field

[0001] The present invention relates to the technical field of traction machines, and more particularly to a copper bar traction machine. Background Art

[0002] Oxygen-free copper bars and copper rods are pure copper products that do not contain oxygen or deoxidizer residues. With their excellent electrical conductivity and processing properties, they are widely used in many fields such as electrical and electronic industries. In the production process of oxygen-free copper bars and copper rods, the upward continuous casting method is a commonly used production process. This process can effectively produce oxygen-free copper rods that meet quality requirements. Subsequently, the oxygen-free copper rods need to be formed by an extruder to make copper bars and copper rods of different specifications and sizes to meet diverse market demands. In the key link of drawing, calibrating and cutting copper rods and copper bars according to specific needs, the traction machine plays an indispensable role.

[0003] At present, the existing traction machines on the market have the problem of low pulling force when used for oxygen-free copper drawing calibration, which cannot meet the large pulling force required for large-sized copper rods and copper bars during the drawing process, resulting in low production efficiency and difficulty in ensuring product quality. They also have a narrow scope of application and are difficult to adapt to the pulling needs of copper products of various specifications and materials, which limits production flexibility. They also have a short traction distance, which forces the production process to be frequently interrupted, increasing production cycle and cost. Finally, they have an excessively fast running speed, which makes it very easy to slip and stall during the traction process, which not only affects production progress but may also cause equipment failure and safety hazards.

[0004] In summary, the existing traction machine can no longer meet the growing demand for the production of large-sized copper rods and copper bars. In view of this, we propose a copper bar traction machine. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0027] Specifically, the copper bar is placed in the traction trolley, and then the operation of the telescopic cylinder 5 drives the pressure plate 6 to move downward. During the downward movement, the pressure plate 6 cooperates with the extrusion portion 7 formed on the inner wall of the bottom of the mobile trolley 3 to clamp the copper bar. When the pressure plate 6 moves down and contacts the copper bar, it can fit closely to the surface of the copper bar, increasing the friction and stability when clamping the copper bar, effectively solving the problem of insufficient pulling force in the existing technology, even in the face of large-sized copper bars, it can provide sufficient traction to ensure production efficiency and product quality, and the pressure plate 6 can be suitable for the traction needs of copper products of various specifications and materials, greatly broadening the application range of the equipment and enhancing the flexibility of production. The wheels 4 arranged on the outer wall of the mobile trolley 3 are located inside the guide rail 2, and the guide rail 2 is fixedly connected to the frame 1 The top of the guide roller makes it possible for the wheel 4 located inside the guide roller to support the moving trolley 3 by abutting against the inner surface of the guide rail 2, and at this time the moving trolley 3 can be moved along the guide rail 2 by the wheel 4, and the driving mechanism can drive the moving trolley 3 to move, so that the moving trolley 3 moves through the pressure plate 6 and the extrusion part 7 to clamp the copper bar and drive the copper bar to move together, effectively controlling the moving distance and speed of the moving trolley 3, and solving the problems of short traction distance and easy slipping and stalling in the prior art. After the copper bar moves, the telescopic cylinder 5 shortens and drives the pressure plate 6 to reset, so that the pressure plate 6 and the extrusion part 7 no longer clamp the copper bar. At this time, the moving trolley 3 is driven to reset by the driving mechanism, and this reciprocating process is repeated, thereby transmitting the copper bar to the feeding port of the drawing machine to complete the traction of the copper bar.

[0028] Furthermore, the driving mechanism includes a supporting plate 8, which is fixedly connected to the inner surface of the frame 1, and a transmission motor 9 is fixedly connected to the top of the supporting plate 8. The two ends of the frame 1 are respectively fixedly connected with symmetrically arranged fixing parts 10, and a transmission shaft 11 is rotatably connected between the fixing parts 10. The outer wall of the transmission shaft 11 is fixedly connected to a first sprocket 12, and a first chain 13 that is meshed with the first sprockets 12 is arranged between the first sprockets 12. The outer wall of the first chain 13 is fixedly connected to the bottom outer wall of the moving trolley 3, and the outer wall of the motor's main shaft is fixedly connected to a second sprocket 14. The outer wall of the transmission shaft 11 is also fixedly connected to a third sprocket 15, and a second chain 16 that is meshed with the second sprocket 14 and the third sprocket 15 is arranged between the second sprocket 14 and the third sprocket 15.

[0029] Specifically, the operation of the transmission motor 9 will drive the second sprocket 14 to rotate, and the outer wall of the frame 1 is fixedly connected with a symmetrically arranged fixing piece 10, and a transmission shaft 11 is also rotatably connected between the fixing pieces 10, and a third sprocket 15 is fixedly connected to the transmission shaft 11, and the third sprocket 15 and the second sprocket 14 are synchronously driven by the second chain 16, and the outer wall of the transmission shaft 11 is also fixedly connected with the first sprocket 12, and the first sprockets 12 are synchronously rotated and connected by the first chain 13, so when the transmission motor 9 is running, it will synchronously drive the transmission shaft 11 to rotate together, and in this process, since the first chain 13 is fixedly connected to the bottom of the mobile trolley 3, the mobile trolley 3 can move on the guide rail 2 through the wheel 4.

[0030] Furthermore, the pressing plate 6 is made of a polyurethane plate, and the specifications of the pressing plate 6 are 30 mm×40 mm×20 mm.

[0031] Specifically, the pressing plate 6 is made of a 30mm*40mm*20mm polyurethane board. The polyurethane is corrosion-resistant and wear-resistant and has flexibility. It fits tightly with the copper busbar and forms a vacuum extrusion area after being squeezed into contact with the copper busbar, thereby increasing the pressing force without scratching the copper busbar. The telescopic pressure of the telescopic cylinder 5 can be controlled to change the pressing force of the pressing plate 6.

[0032] Furthermore, both sides of the top of the frame 1 are fixedly connected with symmetrically arranged connecting members 17, and rollers 18 are rotatably connected between the connecting members 17, and the rollers 18 are symmetrically distributed.

[0033] Specifically, the connecting pieces 17 on both sides of the top of the frame 1 are used to connect the frame 1 and the rollers 18, and the rollers 18 are rotatably connected between the connecting pieces 17, which allows the rollers 18 to rotate, so that the rollers 18 can support the copper busbar, thereby increasing the stability of the copper busbar when moving, and the rollers 18 can rotate due to the friction generated when contacting the copper busbar, so as not to affect the movement of the copper busbar.

[0034] Furthermore, the inner wall of the bottom of the movable trolley 3 is rotatably connected to symmetrically arranged limiting rollers 19, and a limiting channel for the copper busbar to move is formed between the limiting rollers 19.

[0035] Specifically, the limiting rollers 19 are provided to block both sides of the copper busbar, and the copper busbar can move in the limiting channel formed between the limiting rollers 19, thereby preventing the copper busbar from tilting and deviating when being pulled, thereby increasing the stability of the copper busbar when being pulled.

[0036] Furthermore, the inner wall of the movable trolley 3 is rotatably connected to a lower laminating roller 20, and the inner wall of the movable trolley 3 is also provided with an upper laminating roller 21, which is located on the upper side of the lower laminating roller 20, and the upper laminating roller 21 and the lower laminating roller 20 are gradually distributed in a trapezoidal shape.

[0037] Specifically, the copper bar passing through the limiting channel is clamped by the lower laminating roller 20 and the upper laminating roller 21, thereby increasing the stability of the copper bar when passing through the moving trolley 3 and the limiting channel. When the moving trolley 3 is reset, the copper bar is supported by the lower laminating roller 20, thereby preventing excessive friction between the copper bar and the extrusion part 7, which may cause damage to the copper bar.

[0038] Furthermore, a symmetrically arranged slot 22 is provided on the outer wall of the movable carriage 3 . The slot 22 is inclined, and the main shaft of the upper laminating roller 21 is located inside the slot 22 and abuts against the inner wall thereof.

[0039] Specifically, the upper laminating roller 21 slides in the clamping groove 22 by its own gravity, so that the upper laminating roller 21 can be laminated with the upper side of the copper busbar, thereby increasing the clamping effect on the copper busbar.

[0040] Furthermore, travel switches 23 are fixedly connected to the outer walls of both ends of the movable trolley 3 , and the travel switches 23 are electrically connected to the telescopic cylinder 5 and the transmission motor 9 respectively.

[0041] Specifically, after the moving trolley 3 moves and drives the travel switch 23 to move, the travel switch 23 is blocked by the roller 18. At this time, the moving trolley 3 will squeeze the travel switch 23, so that the travel switch 23 is turned on to control the extension and shortening of the telescopic cylinder 5 and the forward and reverse rotation of the transmission motor 9, thereby realizing the automatic reciprocating operation of the moving trolley 3 and the automatic extension and contraction of the telescopic cylinder 5, and realizing automatic traction of the copper busbar.

[0044] The copper rod is placed in the traction trolley, and then the telescopic cylinder 5 is operated to drive the pressing plate 6 to move downward. During the downward movement, the pressing plate 6 cooperates with the extrusion portion 7 formed on the inner wall of the bottom of the mobile trolley 3 to clamp the copper rod. When the pressing plate 6 moves down and contacts the copper rod, it can fit closely to the surface of the copper rod, increasing the friction and stability when clamping the copper rod, effectively solving the problem of insufficient pulling force in the existing technology, even in the face of large-sized copper rods, it can provide sufficient traction to ensure production efficiency and product quality, and the pressing plate 6 can be suitable for the traction needs of copper products of various specifications and materials, greatly broadening the application range of the equipment and enhancing the flexibility of production. The wheels 4 arranged on the outer wall of the mobile trolley 3 are located inside the guide rail 2, and the guide rail 2 is fixedly connected to the top of the frame 1. The wheel 4 located inside the guide roller can support the mobile trolley 3 by abutting against the inner surface of the guide rail 2, and the mobile trolley 3 can be moved along the guide rail 2 by the wheel 4, and the driving mechanism can drive the mobile trolley 3 to move, so that the mobile trolley 3 moves through the pressure plate 6 and the extrusion part 7 to clamp the copper rod and drive the copper rod to move together, effectively controlling the moving distance and speed of the mobile trolley 3, and solving the problems of short traction distance and easy slipping and stalling in the prior art. After the copper rod moves, the telescopic cylinder 5 shortens and drives the pressure plate 6 to reset, so that the pressure plate 6 and the extrusion part 7 no longer clamp the copper rod. At this time, the mobile trolley 3 is driven to reset by the driving mechanism, and it goes back and forth, thereby transmitting the copper rod to the feeding port of the drawing machine to complete the traction of the copper rod.

[0045] Working principle: This embodiment provides a copper bar traction machine. The copper bar is placed in the traction trolley, and then the telescopic cylinder 5 is operated to drive the pressure plate 6 to move downward. During the downward movement, the pressure plate 6 cooperates with the extrusion portion 7 formed on the inner wall of the bottom of the mobile trolley 3, thereby clamping the copper bar.
