At the same time, it improves the flatness and surface quality of the plates through straightening and leveling processes.
[0003] An air-floating bracket is a device that uses compressed air to form an air cushion between the bracket and the supporting surface, achieving suspension and low-friction movement. Due to its advantages such as frictionless operation, high precision, and ground protection, the air-floating bracket has shown significant application value in steel rolling mill cross-cutting equipment. However, in actual use, existing air-floating brackets may deform or be damaged if the weight of the steel plate exceeds the bracket's maximum load-bearing capacity. Therefore, this paper proposes an air-floating bracket for cross-cutting equipment to address these issues. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] This application discloses an air-floating bracket for a cross-cutting device. (Refer to...) Figure 2 and Figure 3An air-floating support for a cross-cutting device includes a base frame 1 and a movable frame 3. A slide rail 2 is fixedly installed on the surface of the base frame 1. An air-floating slider 4 is fixedly installed at the bottom of the movable frame 3. The inner cavity of the air-floating slider 4 is slidably connected to the surface of the slide rail 2. A hydraulic cylinder 5 is fixedly installed at the top of the movable frame 3. The telescopic end of the hydraulic cylinder 5 passes through the movable frame 3 and is slidably connected to the movable frame 3. A pressure plate 6 is fixedly connected to the telescopic end of the hydraulic cylinder 5. An adjustment component 7 is provided inside the movable frame 3. A fixed frame 8 is fixedly installed on the surface of the base frame 1. A tensioning component 9 is provided inside the fixed frame 8. The air-floating slider 4 is a key component that utilizes the static pressure effect of gas to achieve contactless support. It forms a uniform air film between the slider and the guide rail by compressed air, which suspends the slider and eliminates mechanical friction, thereby ensuring high precision, high rigidity and low vibration motion performance. It is widely used in semiconductor manufacturing, precision machining and other fields. It belongs to the prior art and will not be elaborated further here.
[0025] The tensioning assembly 9 includes a rotating rod 91 rotatably connected to the top of the fixed frame 8. The lower end of the rotating rod 91 extends into the interior of the fixed frame 8 and is rotatably connected to the inner cavity of the fixed frame 8. A plurality of winding rollers 92 are fixedly sleeved on the surface of the rotating rod 91. A cable 93 is wound around the surface of each of the winding rollers 92. Both ends of the cable 93 pass through the fixed frame 8 and are slidably connected to the inner cavity of the fixed frame 8. Both ends of the cable 93 are fixedly connected to the two sides of the surface of the base frame 1. A knob 94 is fixedly installed on the top of the rotating rod 91. A positioning assembly 95 is provided on the top of the fixed frame 8. The positioning assembly 95 is used in conjunction with the knob 94.
[0026] When the steel strip is conveyed into the cross-cutting equipment, it is inserted into the moving frame 3, and the pressure plate 6 is pressed down by the hydraulic cylinder 5 so that the pressure plate 6 holds the steel strip. Then, the two sides of the steel strip are positioned by the adjusting component 7 to stabilize the position of the steel strip inside the moving frame 3. Subsequently, the moving frame 3 can be moved by the air float slider 4 and the slide rail 2 to extend one end of the steel strip into the cross-cutting equipment for cross-cutting. When the base frame 1 bears the weight of the steel strip, the position of the rotating rod 91 is supported by the fixed frame 8, the rotating rod 91 supports the position of the winding roller 92, and the winding roller 92 supports the position of the cable 93, so that the cable 93 plays the role of supporting the base frame 1, thereby improving the load-bearing capacity of the base frame 1 and effectively reducing the risk of deformation and damage to the base frame 1.
[0027] Reference Figure 2 and Figure 3A second positioning block 9101 is fixedly installed at the bottom of the rotating rod 91. A positioning groove 9102 is provided inside the fixing frame 8. The surface of the second positioning block 9101 is slidably connected to the inner cavity of the positioning groove 9102. By sliding the surface of the second positioning block 9101 to the inner cavity of the positioning groove 9102, the fixing frame 8 stabilizes the position of the bottom of the rotating rod 91 through the second positioning block 9101 and the positioning groove 9102, so as to avoid the rotating rod 91 from moving longitudinally and ensure the stability of the position of the rotating rod 91.
[0028] Reference Figure 2 and Figure 3 The positioning component 95 includes a spring 9501 fixedly installed on the top of the fixed frame 8. A top plate 9502 is fixedly connected to the top of the spring 9501. The inner cavity of the top plate 9502 is slidably connected to the surface of the rotating rod 91. A locking rod 9503 is fixedly installed on the top of the top plate 9502. A locking groove 9504 is formed on the surface of the knob 94. The surface of the locking rod 9503 is slidably connected to the inner cavity of the locking groove 9504. When it is necessary to adjust the tension of the cable 93, the top plate 9502 is pressed towards the fixed frame 8. To separate the locking plate from the slot 9504, the tension of the cable 93 can be adjusted by rotating the lever 91 through the knob 94. After the tension of the cable 93 is adjusted, the top plate 9502 is released, and the top plate 9502 is reset under the support of the spring 9501. The locking lever 9503 is then inserted into the slot 9504 so that the top plate 9502 stabilizes the position of the knob 94 through the locking lever 9503 and the slot 9504, preventing the knob 94 from rotating back and affecting the tension of the cable 93.
[0029] Reference Figure 2 and Figure 3 A support rod 9505 is fixedly installed on the top of the fixed frame 8. One end of the support rod 9505 passes through the top plate 9502 and is slidably connected to the top plate 9502. By installing the support rod 9505 on the top of the fixed frame 8, the support rod 9505 can stabilize the position of the top plate 9502, so that the top plate 9502 can only move longitudinally, so as to prevent the rotating rod 91 and the knob 94 from rotating and causing the top plate 9502 to rotate at the same time.
[0030] Reference Figure 1 and Figure 4 Positioning rods 61 are fixedly installed on both sides of the top of the pressure plate 6. One end of the positioning rod 61 passes through the moving frame 3 and is slidably connected to the motor. By having one end of the positioning rod 61 pass through the moving frame 3 and is slidably connected to the moving frame 3, the position of the pressure plate 6 is stabilized by the positioning rod 61, so as to avoid the pressure plate 6 from shifting and affecting the pressing work of the steel strip.
[0031] Reference Figure 1 and Figure 4The adjusting component 7 includes a bidirectional screw 71 rotatably connected inside the movable frame 3. The threads on both sides of the surface of the bidirectional screw 71 are opposite, and baffles 72 are threadedly connected to both sides of the surface of the bidirectional screw 71. A limiting rod 73 is fixedly installed inside the movable frame 3. One end of the limiting rod 73 passes through the baffle 72 and is slidably connected to the baffle 72. When the bidirectional screw 71 is rotated, the opposite threads on both sides of the surface of the bidirectional screw 71 cause the two baffles 72 to move towards each other on the surface of the bidirectional screw 71. The limiting rod 73 prevents the baffles 72 from rotating with the bidirectional screw 71, so that the baffles 72 can clamp the steel strip, stabilize the lateral position of the steel strip, and prevent the steel strip from shifting and affecting the cross-cutting effect.
[0032] Reference Figure 1 and Figure 4 Both ends of the bidirectional screw 71 are fixedly installed with a first positioning block 7101, and the surface of the first positioning block 7101 is slidably connected to the inner cavity of the movable frame 3. The first positioning block 7101 can effectively stabilize the position of the bidirectional screw 71 inside the movable frame 3, and avoid the bidirectional screw 71 from shifting and affecting the position of the baffle 72.
[0033] Working principle: When the steel strip enters the cross-cutting equipment, it is inserted into the moving frame 3. The hydraulic cylinder 5 drives the pressure plate 6 to press down, and the positioning rod 61 stabilizes the position of the pressure plate 6, so that the pressure plate 6 presses against the steel strip. Then, the bidirectional screw 71 is rotated, and the position of the bidirectional screw 71 is stabilized by the first positioning block 7101. The opposite threads on both sides of the surface of the bidirectional screw 71 cause the bidirectional screw 71 to drive the two baffles 72 to move towards each other, so that the baffles 72 can clamp the steel strip and stabilize it. The lateral position of the steel strip is adjusted to prevent displacement, thus stabilizing its position within the moving frame 3. The moving frame 3 is then moved via the air-bearing slider 4 and the slide rail 2 to allow one end of the steel strip to be inserted into the cross-cutting equipment for cross-cutting. While the base frame 1 bears the weight of the steel strip, the fixed frame 8 supports the position of the rotating rod 91, which in turn supports the position of the winding roller 92. The winding roller 92, in turn, supports the position of the cable 93, allowing the cable 93 to support the base frame 1, thereby increasing its load-bearing capacity and effectively... To reduce the risk of deformation and damage to the base frame 1, the top plate 9502 is pressed downwards, causing the locking rod 9503 to separate from the locking groove 9504. This prevents the positioning component 95 from positioning the knob 94. Then, the knob 94 is rotated, causing the rotating rod 91 to rotate. The second positioning block 9101 and the second positioning groove 9102 stabilize the position of the rotating rod 91, causing the rotating rod 91 to drive the take-up roller 92 to rotate. The take-up roller 92 then coils the cable 93, thereby achieving the function of winding the cable 93 and adjusting its position. The tension of cable 93 is adjusted. After the tension of cable 93 is adjusted, the top plate 9502 is released. With the support of spring 9501, the top plate 9502 is reset and the position of the top plate 9502 is stabilized by the support rod 9505. This allows the top plate 9502 to drive the locking rod 9503 to reset, so that the locking rod 9503 is inserted into the slot 9504. This, in turn, positions the knob 94 again, thus completing the adjustment of the tension of cable 93, ensuring the load-bearing effect of the base frame 1, and reducing the risk of deformation or damage to the base frame 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
