Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically to a tensioning device for an aluminum alloy horizontal casting machine. Background Technology

[0002] The tensioning device of an aluminum alloy casting machine mainly ensures that the mold maintains a precise position during the casting process and also regulates the pressure. For example, in the aluminum and aluminum alloy wheel-type horizontal casting machine disclosed in Chinese patent literature (application number: 200920037329.X), the tensioning wheel is driven by a cylinder. The cylinder relies on compressed air, and the instability of the air pressure system will cause fluctuations in the tensioning force, making it difficult to maintain a constant tension. The cylinder usually adopts open-loop control, which makes it difficult to achieve high-precision position adjustment and reduces the quality of the products produced by the casting machine. The range of movement of the cylinder-driven tensioning wheel depends on the maximum extension length of the cylinder and cannot be arbitrarily adjusted according to the usage requirements.

[0003] Therefore, we propose a tensioning device for an aluminum alloy horizontal casting machine. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning device for an aluminum alloy horizontal casting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensioning device for an aluminum alloy horizontal casting machine, comprising a casting machine and a tensioning mechanism. The tensioning mechanism includes a mounting frame and a base. A guide rod is provided on the upper part of the mounting frame, and a movable plate is provided on the guide rod. A third U-shaped fixing block is provided on the left side of the movable plate, and a first U-shaped fixing block is provided on the top of the movable plate. A first mounting shaft is provided on the right side of the mounting frame, and a rotating rod is provided on the first mounting shaft. A tensioning wheel is provided on the top of the rotating rod, and a second U-shaped fixing block is provided on the upper left surface of the rotating rod. A first connecting rod is provided on the second U-shaped fixing block. A reduction motor is provided on the top of the base, and a second mounting shaft is provided at the rear end of the reduction motor. A first support rod is provided on the second mounting shaft, and a second support rod is connected to the right end of the first support rod. A positioning block is provided at the rear end of the second support rod, and a threaded rod is provided on the positioning block. A fourth U-shaped fixing block is provided at the right end of the positioning block, and a second connecting rod is provided on the fourth U-shaped fixing block.

[0006] Furthermore, the positioning block has a threaded hole in the middle that mates with the threaded rod. The bottom end of the threaded rod passes through the threaded hole and connects to the second mounting shaft. The bottom end of the threaded rod is connected to the second mounting shaft via a bearing. A cuboid is provided at the top end of the threaded rod.

[0007] Furthermore, the left end of the first support rod is fixedly connected to the second mounting shaft, and both ends of the second support rod are connected to the first support rod and the positioning block respectively via pins.

[0008] Furthermore, the mounting shaft passes through the bottom of the rotating rod, and the bottom of the rotating rod is movably connected to the mounting shaft. The tension wheel is mounted on the upper part of the rotating rod via the shaft.

[0009] Furthermore, the bottom end of the first connecting rod is connected to the first U-shaped fixing block, and both ends of the first connecting rod are connected to the first U-shaped fixing block and the second U-shaped fixing block respectively via pins.

[0010] Furthermore, the right end of the second connecting rod is connected to the third U-shaped fixing block, and both ends of the second connecting rod are connected to the third U-shaped fixing block and the fourth U-shaped fixing block respectively through pins.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the threaded rod rotates, the positioning block moves upward, which in turn moves the left end of the second support rod upward. Simultaneously, the fourth U-shaped fixing block moves upward, changing the distance between the fourth U-shaped fixing block and the second mounting shaft. When the second mounting shaft rotates, the arc diameter of the fourth U-shaped fixing block rotating around the mounting shaft increases. With the same angle of rotation of the mounting shaft, the arc of the fourth U-shaped fixing block increases, increasing the moving distance of the moving plate. This, in turn, increases the arc length of the tensioning wheel, allowing the tensioning wheel to be adjusted arbitrarily according to usage needs. This allows the tensioning mechanism to be adjusted arbitrarily according to the actual tensioning requirements based on the installation site of the casting machine and the production process of the steel strip.

[0013] 2. The rotation of the second mounting shaft drives the first and second support rods to rotate. The second connecting rod drives the moving plate to move. The moving plate pulls the rotating rod through the first connecting rod to rotate, thereby precisely adjusting the position of the tension wheel and maintaining a constant tension in the tension wheel.

The U-shaped fixing block 20 pulls the third U-shaped fixing block 12 to the left via the second connecting rod 21. The third U-shaped fixing block 12 drives the moving plate 5 to move to the left on the guide rod 4. The moving plate 5 drives the bottom of the first connecting rod 10 to move to the left via the first U-shaped fixing block 6. The right end of the first connecting rod 10 drives the rotating rod 8 to rotate to the left by pulling the second U-shaped fixing block 9, thereby causing the tensioning wheel 11 to rotate to the left, tightening the annular steel strip on the casting machine, and rotating the threaded rod 19.

During the rotation of the threaded rod 19, the positioning block 18 moves upward by mates with the threaded hole. 8 drives the left end of the second support rod 17 to move upward, and at the same time the fourth U-shaped fixing block 20 moves upward, changing the distance between the fourth U-shaped fixing block 20 and the second mounting shaft 15. When the second mounting shaft 15 rotates, the arc diameter of the fourth U-shaped fixing block 20 rotating around the second mounting shaft 15 becomes larger. Under the same rotation angle of the second mounting shaft 15, the arc of the fourth U-shaped fixing block 20 is increased, which increases the moving distance of the moving plate 5, thereby increasing the arc length of the tensioning wheel 11. The tensioning wheel 11 can be adjusted arbitrarily according to the usage needs, and the tensioning mechanism 2 can be adjusted arbitrarily according to the actual tensioning requirements based on the installation site of the casting machine and the production process of the steel strip.

When the first connecting rod 10 pulls the second U-shaped fixing block 9, the two ends of the first connecting rod 10 rotate through the pins.

[0022] Reference embodiment: The right end of the second connecting rod 21 is connected to the third U-shaped fixing block 12. The two ends of the second connecting rod 21 are respectively connected to the third U-shaped fixing block 12 and the fourth U-shaped fixing block 20 through pins.
