Description

Technical Field

[0001] This invention relates to the field of oxygen-free copper rod production equipment, and in particular to a continuous casting oxygen-free copper rod traction device. Background Technology

[0002] Oxygen-free copper rod is a semi-finished copper product produced through special processes such as upward continuous casting or continuous casting and rolling. Its core characteristics are extremely low oxygen content (usually ≤10ppm, or parts per million), and the total amount of impurities is controlled at an extremely low level. With its excellent electrical conductivity, thermal conductivity and processing toughness brought about by "extremely low oxygen content and extremely high purity", it has become an irreplaceable key basic material in high-end electrical engineering, electronics and special application fields.

[0003] In continuous casting production of oxygen-free copper rods, the traction process is a crucial step in ensuring the quality of the final product. Because the copper rod is still at a high temperature during the drawing and traction process, it is prone to softening and deformation due to factors such as vibration or its own weight. Current traction equipment cannot effectively guarantee that the copper rod maintains high straightness, affecting subsequent rolling or coiling processes. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous casting oxygen-free copper rod traction device to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

A movable frame is horizontally slidably installed inside the traction platform. A drive mechanism is provided on the side wall of the traction platform. The drive mechanism is connected to the traction wheels and synchronously drives the movable frame to reciprocate horizontally. Limiting sleeves are fixed to both ends of the movable frame via connecting plates. A straightening mechanism is provided between the two limiting sleeves. The straightening mechanism includes a mounting base. A set of mounting plates is symmetrically arranged on the upper end of the mounting base. The oxygen-free copper rod horizontally passes through the limiting sleeves and the mounting plates. Sliding blocks that can slide radially are evenly distributed in a cross shape on the side wall of the mounting plates. Each sliding block is fixed to an arc-shaped pressure plate via a connecting block. The limiting sleeve is connected to the corresponding sliding block and synchronously drives the arc-shaped pressure plate to perform alternating horizontal and vertical centering and straightening of the oxygen-free copper rod.

The output end of the driving motor is respectively provided with a driving wheel and a toothed gear. Transmission wheels are rotatably mounted at both ends of the side wall of the traction table. Each set of traction rollers is rotatably mounted in the mounting frame, and one of the traction rollers is connected to the transmission wheel through a connecting shaft. Guide wheels are rotatably mounted on both sides of the driving wheel. The driving wheel, transmission wheel and guide wheel are connected by a transmission belt.

[0009] As a further aspect of the present invention: the inner walls at both ends of the movable frame are provided with mating tooth grooves, and the toothless gear intermittently meshes with the mating tooth grooves.

[0010] As a further embodiment of the present invention: a cleaning mechanism and a plating solution mechanism are respectively provided at both ends of the inner wall of the traction table. The cleaning mechanism is located at the front end of the straightening mechanism along the traction direction of the oxygen-free copper rod, and the cleaning mechanism is located at the rear end of the straightening mechanism along the traction direction of the oxygen-free copper rod.

[0011] As a further aspect of the present invention: the cleaning mechanism includes a piston cylinder, which is fixedly mounted on the inner wall of the traction platform. Piston rods are fixedly connected to both ends of the movable frame. One end of the piston rod extends into the piston cylinder and divides its inner cavity into two sections. Each section of the piston cylinder is connected to an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to an external air source, and the air outlet pipe is connected to a ventilation pipe. The end of the ventilation pipe is connected to a cleaning ring pipe through which an oxygen-free copper rod passes coaxially. A plurality of nozzles facing the oxygen-free copper rod are evenly arranged circumferentially on the inner wall of the cleaning ring pipe.

[0014] As a further aspect of the present invention: return springs are provided at both ends of the movable frame between the piston cylinder and the piston liquid cylinder.

[0015] The beneficial effects of this invention are:

[0016] (1) By setting up a drive mechanism, a limiting sleeve and a straightening mechanism, the drive mechanism drives the traction wheel sets at both ends to traction and transport the oxygen-free copper rod, and simultaneously drives the movable frame and the limiting sleeve to reciprocate in a horizontal linear motion, so that the limiting sleeve can limit and straighten the oxygen-free copper rod during traction and transport. At the same time, the reciprocating motion of the limiting sleeve is coordinated with the centering and pressing process of the arc-shaped pressure plate, so that the limiting sleeve drives the left and right and upper and lower arc-shaped pressure plates to perform horizontal and vertical alternating pressing and straightening of the oxygen-free copper rod, effectively ensuring that the oxygen-free copper rod remains straight and does not bend or deform during traction and transport, thereby improving the straightness of the oxygen-free copper rod to facilitate subsequent processing.

[0017] (2) By setting up a cleaning mechanism and a plating solution mechanism, the movable frame will synchronously drive the piston rod to be pulled back and forth in the piston air cylinder and piston liquid cylinder during the reciprocating motion. The piston air cylinder can continuously exhaust and intake air, thereby continuously spraying air to clean the oxygen-free copper rod during the traction and conveying process.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-5 As shown, this invention is a continuous casting oxygen-free copper rod traction device, including a traction platform 1. Two sets of traction wheels for traction of the oxygen-free copper rod are provided at both ends of the traction platform 1. A movable frame 2 is horizontally slidably installed inside the traction platform 1. A drive mechanism 7 is provided on the side wall of the traction platform 1. The drive mechanism 7 is connected to the traction wheels and synchronously drives the movable frame 2 to reciprocate horizontally. Limit sleeves 203 are fixedly connected to both ends of the movable frame 2 via connecting plates 202. A straightening mechanism 4 is provided between the two limit sleeves 203. The straightening mechanism 4 includes... The device includes a mounting base 401, on the upper end of which a set of mounting plates 402 are symmetrically arranged. The oxygen-free copper rod passes horizontally through the limiting sleeve 203 and the mounting plate 402. The side wall of the mounting plate 402 has radially sliding sliding blocks 404 evenly distributed in a cross shape. Each sliding block 404 is fixed to an arc-shaped pressure plate 406 through a connecting block 405. The limiting sleeve 203 is connected to the corresponding sliding block 404 and synchronously drives the arc-shaped pressure plate 406 to perform alternating horizontal and vertical centering and straightening of the oxygen-free copper rod.

[0029] Specifically, by setting up a drive mechanism 7, a limiting sleeve 203, and a straightening mechanism 4, the drive mechanism 7 drives the traction wheel sets at both ends to traction and transport the oxygen-free copper rod, and simultaneously drives the movable frame 2 and the limiting sleeve 203 to reciprocate horizontally in a linear motion. This allows the limiting sleeve 203 to limit and straighten the oxygen-free copper rod during traction and transport. At the same time, the reciprocating motion of the limiting sleeve 203 is coordinated with the centering and pressing process of the arc-shaped pressure plate 406, so that the limiting sleeve 203 drives the left and right and upper and lower sets of arc-shaped pressure plates 406 to perform alternating horizontal and vertical pressing and straightening of the oxygen-free copper rod. This effectively ensures that the oxygen-free copper rod remains straight and does not bend or deform during traction and transport, thereby improving the straightness of the oxygen-free copper rod and facilitating subsequent processing.

[0030] like Figure 4 and Figure 5 As shown, slide rails 403 are evenly arranged on the side wall of the mounting plate 402. Sliding blocks 404 are adapted to slide and are slidably installed in the slide rails 403. A pull rod 407 is rotatably installed between two adjacent sliding blocks 404. A compression spring 408 is provided between the left and right sliding blocks 404 and the side wall of the slide rail 403. A connecting rod 204 is provided between the upper and lower sliding blocks 404 and the corresponding limiting sleeves 203. The two ends of the connecting rod 204 are rotatably engaged with the sliding block 404 and the limiting sleeve 203 respectively. A clearance groove 4021 for the connecting rod 204 to move is provided through the mounting plate 402.

[0031] Specifically, when the movable frame 2 moves to the left, the left limiting sleeve 203 pulls the upper and lower sliding blocks 404 closer together via the connecting rod 204, and uses the arc-shaped pressure plate 406 to longitudinally center and compress the oxygen-free copper rod. At this time, the left and right sliding blocks 404 move away from each other under the pushing and pulling action of the pull rod 407. Simultaneously, the right limiting sleeve 203 pushes the other set of upper and lower sliding blocks 404 away from each other via the connecting rod 204. The left and right sliding blocks 404 move closer together under the transmission action of the pull rod 407, and use the arc-shaped pressure plate 406 to laterally center and compress the oxygen-free copper rod, so that the oxygen-free copper rod can always be subjected to centering and compressing forces in both the horizontal and vertical directions. When the movable frame 2 moves to the right, the sliding blocks 404 move in the opposite direction, and the arc-shaped pressure plate 406, which was originally far away, will begin to compress the oxygen-free copper rod, thus realizing an alternating horizontal and vertical centering and compressing process, making the oxygen-free copper rod subjected to uniform compression force and improving the limiting and straightening effect.

[0032] like Figures 2-4As shown, the drive mechanism 7 includes a drive motor 701, which is fixed on the side wall of the traction table 1. The output end of the drive motor 701 is respectively provided with a drive wheel 702 and a toothed gear 703. Transmission wheels 704 are rotatably installed at both ends of the side wall of the traction table 1. Each set of traction rollers 3 is rotatably installed in the mounting frame 301, and one of the traction rollers 3 is connected to the transmission wheel 704 through the connecting shaft 302. Guide wheels 706 are rotatably installed on both sides of the drive wheel 702. The drive wheel 702, the transmission wheel 704 and the guide wheel 706 are connected by a transmission belt 705.

[0033] Furthermore, the inner walls at both ends of the movable frame 2 are provided with mating tooth grooves 201, and the toothless gear 703 intermittently meshes with the mating tooth grooves 201.

[0034] Specifically, when the drive motor 701 starts, it drives the drive wheel 702 to rotate. The drive wheel 702 then drives the transmission wheel 704 to rotate synchronously via the transmission belt 705. The transmission wheel 704 then drives the corresponding traction roller 3 to rotate via the connecting shaft 302, thereby realizing the traction drive process of the oxygen-free copper rod. The guide wheels 706 are arranged on both sides of the drive wheel 702, which effectively increases the wrap angle between the drive wheel 702 and the transmission belt 705, thereby increasing friction and thus increasing the rotational output torque. The drive motor 701 also synchronously drives the toothed gear 703 to rotate. During rotation, the toothed gear 703 intermittently meshes with the mating tooth groove 201, thereby realizing the left-right reciprocating linear motion of the movable frame 2.

[0035] like Figure 6 As shown, a cleaning mechanism 5 and a plating solution mechanism 6 are respectively provided at both ends of the inner wall of the traction table 1. The cleaning mechanism 5 is located at the front end of the straightening mechanism 4 along the traction direction of the oxygen-free copper rod, and the cleaning mechanism 5 is located at the rear end of the straightening mechanism 4 along the traction direction of the oxygen-free copper rod.

[0036] Specifically, by setting up a cleaning mechanism 5 and a plating solution mechanism 6, the cleaning mechanism 5 can blow air to clean the oxygen-free copper rod to ensure the smoothness of the copper rod surface, while the plating solution mechanism 6 can evenly spray a protective liquid on the copper rod surface to form an isolation film to prevent the copper rod from oxidizing.

[0037] like Figure 6 and Figure 7As shown, the cleaning mechanism 5 includes a piston cylinder 501, which is fixed on the inner wall of the traction platform 1. Piston rods 205 are fixed to both ends of the movable frame 2. One end of the piston rod 205 extends into the piston cylinder 501 and divides its inner cavity into two sections. Each section of the piston cylinder 501 is connected to an air inlet pipe 5011 and an air outlet pipe 502. The air inlet pipe 5011 is connected to an external air source, and the air outlet pipe 502 is connected to a ventilation pipe 503. The end of the ventilation pipe 503 is connected to a cleaning ring pipe 504 through which the oxygen-free copper rod passes coaxially. Several nozzles 5041 facing the oxygen-free copper rod are evenly arranged circumferentially on the inner wall of the cleaning ring pipe 504.

[0038] Furthermore, a one-way valve 5012 is provided on the air inlet pipe 5011, and a one-way valve 5021 is provided on the air outlet pipe 502. The direction of the one-way valve 5012 is from the outside to the piston cylinder 501, and the direction of the one-way valve 5021 is from the piston cylinder 501 to the vent pipe 503.

[0039] Specifically, during the reciprocating linear motion of the movable frame 2, the piston rod 205 will be simultaneously pulled back and forth within the piston cylinder 501. When the piston rod 205 moves to the left, the gas in the left air chamber will be pushed out through the left exhaust pipe 502, while the right air chamber will begin to draw in air through the right intake pipe 5011. When the piston rod 205 moves to the right, the gas in the right air chamber will be pushed out through the right exhaust pipe 502, while the left air chamber will begin to draw in air through the left intake pipe 5011. This allows the piston rod 205 to continuously perform exhaust and intake processes during the reciprocating motion, thereby continuously cleaning the oxygen-free copper rod during the traction and conveying process with air jets.

[0040] like Figure 6 As shown, the plating solution mechanism 6 includes a piston liquid cylinder 601, a liquid outlet pipe 602, a liquid passage pipe 605, and a plating solution ring pipe 604. The structural arrangement of the piston liquid cylinder 601 and piston air cylinder 501, the liquid outlet pipe 602 and air outlet pipe 502, the liquid passage pipe 605 and air passage pipe 503, and the plating solution ring pipe 604 and cleaning ring pipe 504 are consistent.

[0041] Specifically, the operating principle of the plating mechanism 6 is the same as that of the cleaning mechanism 5, except that the sprayed medium is changed from gas to protective liquid. When the piston rod 205 at the other end is pulled back and forth in the piston liquid cylinder 601, the piston liquid cylinder 601 will carry out a continuous process of liquid discharge and liquid inlet, thereby continuously spraying liquid onto the oxygen-free copper rod in the traction and conveying process to form a continuous protective isolation film.

[0042] like Figure 6As shown, reset springs 206 are provided at both ends of the movable frame 2 between the piston cylinder 501 and the piston liquid cylinder 601. The reset springs 206 can be used to facilitate the movement and reset of the movable frame 2.

[0043] The working principle of this invention is as follows: Figures 1-7 As shown, during use, the drive motor 701 starts and drives the drive wheel 702 to rotate. The drive wheel 702 drives the transmission wheel 704 to rotate synchronously via the transmission belt 705. The transmission wheel 704 drives the corresponding traction roller 3 to rotate via the connecting shaft 302, thereby realizing the traction drive process of the oxygen-free copper rod. The drive motor 701 also synchronously drives the toothed gear 703 to rotate. During the rotation, the toothed gear 703 intermittently meshes with the mating tooth groove 201, thereby realizing the left and right reciprocating linear motion of the movable frame 2. When the movable frame 2 moves to the left, the left limiting sleeve 203 pulls the upper and lower sliding blocks 404 closer together via the connecting rod 204, and uses the arc-shaped pressure plate 406 to longitudinally center and compress the oxygen-free copper rod. At this time, the left and right sliding blocks 404 move away from each other under the pushing and pulling action of the pull rod 407. Simultaneously, the right limiting sleeve 203 pushes the other set of upper and lower sliding blocks 404 away from each other via the connecting rod 204. The left and right sliding blocks 404 move closer together under the transmission action of the pull rod 407, and use the arc-shaped pressure plate 406 to laterally center and compress the oxygen-free copper rod, so that the oxygen-free copper rod can always be subjected to centering and compressing forces in both the horizontal and vertical directions. When the movable frame 2 moves to the right, the sliding blocks 404 move in the opposite direction, and the arc-shaped pressure plate 406, which was originally far away, will begin to compress the oxygen-free copper rod, thus realizing an alternating horizontal and vertical centering and compressing process, making the oxygen-free copper rod subjected to uniform compressing force and improving the limiting and straightening effect. During the reciprocating linear motion of the movable frame 2, the piston rod 205 is synchronously pulled back and forth in the piston cylinder 501. When the piston rod 205 moves to the left, the gas in the left air chamber is pushed out through the left exhaust pipe 502, while the right air chamber begins to draw in air through the right intake pipe 5011. When the piston rod 205 moves to the right, the gas in the right air chamber is pushed out through the right exhaust pipe 502, while the left air chamber begins to draw in air through the left intake pipe 5011. This allows the piston rod 205 to continuously exhaust and intake air during the reciprocating motion, thereby continuously cleaning the oxygen-free copper rod during the traction and conveying process with air jets. Similarly, when the piston rod 205 at the other end is reciprocated in the piston cylinder 601, the piston cylinder 601 will undergo a continuous process of liquid discharge and liquid intake, thereby continuously spraying liquid onto the oxygen-free copper rod during the traction and conveying process to form a continuous protective isolation film.

[0044] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
