Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting processing, in particular to a clamp for continuous casting. Background Art

[0002] The three major parts of continuous casting refer to the three key functional refractory components used in the continuous casting process, namely the integral stopper rod, the long nozzle and the immersed nozzle. During the continuous casting production process, the installation and replacement of these components require the use of fixtures.

[0003] Since the current continuous casting fixture cannot be finely adjusted after being fixed to the bracket in the corresponding position, if there is a slight deviation in the position of the continuous casting installed on the fixture (such as height and angle deviation), this may cause the stability of the entire continuous casting process to deteriorate, and the fixture needs to be disassembled and the position adjusted, which affects the product quality and production efficiency and is difficult to meet usage requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp for continuous castings, which has the advantages of being able to adjust the position of the clamp, improve processing tolerance, and optimize processing efficiency, thereby solving the problem that the current continuous casting processing clamp is inconvenient to adjust the position and angle when in use.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] The utility model includes a clamping mechanism, an angle adjustment mechanism is arranged below the clamping mechanism, and a height adjustment mechanism is arranged below the angle adjustment mechanism; the angle adjustment mechanism includes a U-shaped plate, a side plate is fixed on the top of the U-shaped plate, a worm is rotatably connected to the surface of the side plate, a worm wheel is meshed on the surface of the worm, a rotating shaft is fixed on the surface of the worm wheel, a bearing seat is fixed on the top of the U-shaped plate, the rotating shaft is fixedly connected to the inner wall of the bearing seat, and a top plate is fixed on the top of the rotating shaft.

[0007] As a preferred fixture for continuous castings of the utility model, a support plate is fixed on the top of the U-shaped plate, and the surface of the support plate is slidably connected to the surface of the top plate.

[0008] As a preferred clamp for continuous castings of the utility model, the clamping mechanism includes two connecting plates, a bottom clamping plate is fixed between the connecting plates on both sides, a U-shaped frame is rotatably connected to the surface of the right connecting plate, an adjusting screw is threadedly connected to the surface of the U-shaped frame, the bottom of the adjusting screw is rotatably connected to a clamping seat, and a top clamping plate is fixed to the bottom of the clamping seat.

[0009] As a preferred fixture for continuous castings of the utility model, a pin rod penetrates the surface of the left connecting plate, and a slot for matching the pin rod is opened at the lower left side of the surface of the U-shaped frame.

[0010] As a preferred clamp for continuous castings of the utility model, the surfaces of the bottom clamping plate and the top clamping plate are both arranged in a V-shaped stepped structure.

[0011] As a preferred fixture for continuous castings of the utility model, the height adjustment mechanism includes a connecting seat, a mounting plate is fixed on the top of the connecting seat, the surface of the mounting plate is rotatably connected to a positive and negative screw rod, the surface of the positive and negative screw rod is threadedly connected to two slides, and a linkage plate is hinged on the top of the slide.

[0012] As a preferred fixture for continuous castings of the utility model, a guide rail is fixed on the top of the connecting seat, and the surface of the slide is slidably connected to the surface of the guide rail.

[0013] The positive effects of the utility model are as follows:

[0014] 1. The clamping mechanism of the utility model can clamp and quickly release the continuous casting. When the angle needs to be adjusted after the clamping mechanism clamps the continuous casting, rotating the rotating handle can drive the worm to rotate, and the worm can drive the worm wheel to rotate when rotating. At the same time, because the worm wheel cannot drive the worm to rotate, the worm wheel can self-lock after rotation. When the worm wheel rotates, the rotating shaft drives the top plate to rotate, and the clamping mechanism drives the continuous casting to rotate horizontally with the rotating shaft as the center. Through this design, according to the structure and process requirements of different continuous casting machines, the angle of the component can be quickly adjusted to ensure the best alignment of the stopper rod, the water nozzle and the pouring system, reduce the occurrence of unstable flow, blockage or deviation of molten steel, and after replacing or repairing the components, the angle can be fine-tuned without completely removing the original fixing device, saving time and improving maintenance efficiency.

[0015] 2. The angle adjustment mechanism of the utility model allows the angle of the continuous casting to be adjusted after clamping, and the continuous casting can be placed between the top clamping plate and the bottom clamping plate. When the adjusting screw is rotated, the adjusting screw can be moved on the surface of the U-shaped frame, so that the clamping seat moves toward the bottom clamping plate, so that the continuous casting can obtain a clamping effect. When the continuous casting needs to be released after processing, the U-shaped frame can be directly rotated upward to make the U-shaped frame rotate with the top of the right connecting plate as the center point, so that the top of the bottom clamping plate is opened, so that the clamp can realize fast loading and unloading of workpieces. Especially when replacing continuous castings such as integral stoppers, long water nozzles or immersed water nozzles, the operation can be completed by opening half of the clamp, which greatly shortens the time required for replacement and adjustment, thereby improving production efficiency.

[0016] 3. The height adjustment mechanism of the utility model can adjust the height after clamping the continuous casting. When the height of the clamped continuous casting needs to be adjusted, the hand wheel can be turned to rotate the positive and negative screws. Since the threads on the surfaces of the positive and negative screws are in opposite directions, the two slides move in opposite directions on the surfaces of the positive and negative screws. At the same time, when the slide moves, the hinge angle between the linkage plate, the slide and the U-shaped plate will change, thereby changing the height position of the U-shaped plate and realizing the adjustment of the height position of the continuous casting. In the continuous casting process, due to factors such as wear and erosion, the height of the stopper rod and the water nozzle may need to be adjusted in time. The utility model ensures that the ideal pouring position is still maintained after the parts are worn, thereby ensuring the smooth and stable flow of molten steel and improving the reliability of the device.

[0022] See also Figure 1-4 A clamp for continuous castings, comprising a clamping mechanism 1, an angle adjustment mechanism 2 is arranged below the clamping mechanism 1, and a height adjustment mechanism 3 is arranged below the angle adjustment mechanism 2;

[0023] The clamping mechanism 1 enables the continuous casting to be clamped and quickly released, the angle adjustment mechanism 2 enables the continuous casting to be angle adjusted after clamping, and the height adjustment mechanism 3 enables the continuous casting to be height adjusted after clamping.

[0024] The angle adjustment mechanism 2 includes a U-shaped plate 201, a side plate 202 is fixed on the top of the U-shaped plate 201, a worm 203 is rotatably connected to the surface of the side plate 202, one end of the worm 203 passes through the front side plate 202 and is fixed with a rotating handle, a worm wheel 204 is meshed on the surface of the worm 203, a rotating shaft 206 is fixed on the surface of the worm wheel 204, a bearing seat 205 is fixed on the top of the U-shaped plate 201, the rotating shaft 206 is fixedly connected to the inner wall of the bearing seat 205, and a top plate 207 is fixed on the top of the rotating shaft 206;

[0025] When the clamping mechanism 1 needs to adjust the angle after clamping the continuous casting, rotating the rotating handle can drive the worm 203 to rotate, and the worm 203 can drive the worm wheel 204 to rotate when rotating. At the same time, because the worm wheel 204 cannot drive the worm 203 to rotate, the worm wheel 204 can obtain a self-locking effect after rotation. When the worm wheel 204 rotates, the rotating shaft 206 will drive the top plate 207 to rotate together, so that the clamping mechanism 1 can drive the continuous casting to rotate horizontally with the rotating shaft 206 as the center point. Through this design, the angle of the component can be quickly adjusted according to the structure and process requirements of different continuous casting machines to ensure the best alignment of the stopper rod, the water nozzle and the pouring system, reduce the occurrence of unstable flow, blockage or deviation of the molten steel, and after replacing or repairing the components, the angle can be fine-tuned without completely removing the original fixing device, saving time and improving maintenance efficiency.

[0026] Furthermore, a support plate 208 is fixed on the top of the U-shaped plate 201, and the surface of the support plate 208 is slidably connected to the surface of the top plate 207;

[0027] The top plate 207 can slide on the top of the support plate 208, and the support plate 208 can provide additional support for the top plate 207, thereby ensuring the stability of the top plate 207 when rotating.

[0028] Further, the clamping mechanism 1 includes two connecting plates 101, a bottom clamping plate 102 is fixed between the connecting plates 101 on both sides, a U-shaped frame 103 is rotatably connected to the surface of the right connecting plate 101, an adjusting screw rod 104 is threadedly connected to the surface of the U-shaped frame 103, a clamping seat 105 is rotatably connected to the bottom of the adjusting screw rod 104, a top clamping plate 106 is fixed to the bottom of the clamping seat 105, and the top of the top plate 207 is fixedly connected to the connecting plate 101 and the bottom of the bottom clamping plate 102;

[0029] The continuous casting can be placed between the top clamping plate 106 and the bottom clamping plate 102, and when the adjusting screw rod 104 is rotated, the adjusting screw rod 104 can be moved on the surface of the U-shaped frame 103, so that the clamping seat 105 can move toward the bottom clamping plate 102, so that the continuous casting can obtain a clamping effect. When the continuous casting needs to be released after processing, the U-shaped frame 103 can be directly rotated upward to make the U-shaped frame 103 rotate around the top of the right connecting plate 101 as the center point, so that the top of the bottom clamping plate 102 is opened, so that the clamp can realize fast loading and unloading of workpieces, especially when replacing continuous castings such as integral stopper rods, long water nozzles or immersed water nozzles, only half of the clamp needs to be opened to complete the operation, which greatly shortens the time required for replacement and adjustment, thereby improving production efficiency.

[0030] Furthermore, a pin rod 107 is passed through the surface of the left connecting plate 101, and a slot for cooperating with the pin rod 107 is opened at the lower left side of the surface of the U-shaped frame 103;

[0031] After the pin 107 is inserted into the slot on the surface of the U-shaped frame 103 and the inside of the left connecting plate 101, the U-shaped frame 103 can obtain a limiting effect, thereby ensuring that the U-shaped frame 103 will not rotate upward by itself during the clamping process of the clamping seat 105 clamping the continuous casting.

[0032] Furthermore, the surfaces of the bottom clamping plate 102 and the top clamping plate 106 are both arranged in a V-shaped stepped structure;

[0033] The V-shaped design can adapt well to the shape of the part to be clamped, and is more suitable for the three large round continuous castings. The stepped design means that it can adapt to continuous castings of different diameters or different wear stages. By selecting different step positions, it can be ensured that effective clamping can be obtained even when the part size changes slightly.

[0034] Furthermore, the height adjustment mechanism 3 includes a connecting seat 301, a mounting plate 302 is fixed on the top of the connecting seat 301, a positive and negative threaded rod 303 is rotatably connected to the surface of the mounting plate 302, one end of the positive and negative threaded rod 303 passes through the connecting seat 301 and is fixed with a hand wheel, and two slides 304 are threadedly connected to the surface of the positive and negative threaded rod 303, a linkage plate 305 is hinged on the top of the slide 304, and the top of the linkage plate 305 is hinged to the bottom of the U-shaped plate 201;

[0035] When it is necessary to adjust the height of the clamped continuous casting, turning the hand wheel can rotate the positive and negative screw rods 303. Since the threads on the surfaces of the positive and negative screw rods 303 are in opposite directions, the two slides 304 can move towards or in opposite directions on the surfaces of the positive and negative screw rods 303. At the same time, when the slide 304 moves, the hinge angle between the linkage plate 305 and the slide 304 and the U-shaped plate 201 will change, thereby changing the height position of the U-shaped plate 201 and adjusting the height position of the continuous casting. In the continuous casting process, due to factors such as wear and erosion, the height of the stopper rod and the water nozzle may need to be adjusted in time. Through this design, the clamp can ensure that the ideal pouring position is maintained after the parts are worn, thereby ensuring the smooth and stable flow of molten steel and improving the practicality of the device.

[0036] Furthermore, a guide rail 306 is fixed on the top of the connecting seat 301, and the surface of the slide 304 is slidably connected to the surface of the guide rail 306;

[0037] The slide 304 can slide on the surface of the guide rail 306, and the guide rail 306 can provide guidance and support for the slide 304, so as to avoid that all the weight above the U-shaped plate 201 is borne by the positive and negative screw rods 303, thereby improving the service life of the positive and negative screw rods 303.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
