Description

Technical Field

[0001] This utility model relates to a gear clamping device for a high-temperature sawing production line for aluminum alloy rolled plates, belonging to the field of metal sheet processing technology. Background Technology

[0002] The common process for producing hot-rolled aluminum alloy sheets is as follows: Small aluminum ingots are melted and cast into large aluminum ingots approximately 3-6m long, 1-2.6m wide, and 0.65m thick. A milling machine removes the coarse oxide layer from the surface of the large aluminum ingots. The ingots are then heated to 500-600℃ in a furnace and placed on a roller conveyor. A hot rolling mill rolls the ingots back and forth into thin sheets 80-150m long. After rolling, the sheets are conveyed to a sawing machine, which cuts them into short aluminum sheets of 3-8m. These sheets are then picked up by a vacuum robotic arm and stacked to the side before being removed. During the sawing process, the sheets need to be clamped. However, existing clamping devices suffer from uneven pressure on both sides, causing the sheet position to shift after clamping, reducing positioning accuracy and compromising sawing quality. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a gear clamping device for a high-temperature sawing production line of aluminum alloy rolled plate, which is compact in structure, easy to operate, realizes synchronous clamping, avoids unequal thrust on both sides, and improves positioning accuracy and sawing quality.

The two ends of the crossbeam unit are fixed to the inner wall of the frame. A clamping unit is provided on the crossbeam unit. Each clamping unit includes two symmetrically arranged clamping supports. Clamping blocks are provided on the clamping supports. A synchronous guiding mechanism is provided between the two clamping supports to drive the clamping supports to move closer synchronously so that the two clamping blocks clamp the rolled plate, or the clamping supports to move away synchronously so that the two clamping blocks release the rolled plate.

[0005] Each of the clamping supports includes two oppositely arranged side plates, the side plates being located outside the crossbeam unit, and a top plate being provided between the tops of the two side plates.

[0006] The synchronous guiding mechanism includes roller mounting seats, and roller mounting seats are respectively provided on the inner side of the side plate. Rollers are provided on the roller mounting seats. The crossbeam unit includes two parallel crossbeams, and guide rods are respectively provided on the top of the crossbeams. The rollers are mounted on the guide rods. A vertically arranged central gear is also provided between the two crossbeams. Racks are respectively provided on the roller mounting seats. The two racks are staggered and mesh with the central gears respectively.

[0007] Support beams are symmetrically arranged on both sides of the crossbeam unit, and heat insulation covers are respectively provided between the clamping side of the clamping block and the two support beams.

[0008] Multiple sets of detection units are symmetrically arranged on the outer side of the frame, and the multiple sets of detection units correspond to the clamping unit; each detection unit includes a detection fixing block, and the detection fixing block is provided with a vertically arranged detection frame, and the detection frame is provided with a detection switch, which is used to detect whether the material is in place.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 , 2As shown in Figures 3, 4, and 5, a gear clamping device for a high-temperature sawing production line of aluminum alloy rolled plates in this embodiment includes a frame 1. Multiple evenly spaced cover plates 5 are mounted inside the frame 1. A crossbeam unit is provided between adjacent cover plates 5. Each crossbeam unit includes two parallel crossbeams 2, with both ends of the crossbeams 2 mounted on the inner wall of the frame 1. Vertically arranged support beams 3 are symmetrically arranged on the outer side of the crossbeams 2. Clamping units are provided on each crossbeam unit for clamping the rolled plate. Each clamping unit includes two symmetrically arranged clamping supports. Two symmetrically arranged cylinder mounting plates 4 are provided inside the two crossbeams 2. A horizontally arranged clamping cylinder 10 is mounted on the cylinder mounting plate 4. The extension rod of the clamping cylinder 10 is fixedly connected to the clamping support through a cylinder connecting joint 15. A clamping block 9 is provided on the clamping support. A synchronous guiding mechanism is also provided between the two clamping supports; the two clamping cylinders 10 extend, and the synchronous guiding mechanism makes the two clamping supports and the two clamping blocks 9 move closer to each other to clamp the rolling plate, so that the thrust on both sides of the rolling plate is the same, avoiding the displacement of the rolling plate, or making the two clamping supports and the two clamping blocks move away from each other to release the rolling plate.

[0018] The clamping support includes two oppositely arranged side plates 7, which are located outside the corresponding side beams 2. A top plate 6 is provided between the two beams 2, and the top plate 6 is fixed to the top of the two side plates 7.

[0019] The synchronous guiding mechanism includes roller mounting seats 17, with roller mounting seats 17 respectively installed on the inner side of the side plates 7, and rollers 11 mounted on the roller mounting seats 17. A horizontally arranged, continuous guide rod 12 is installed on the top of each crossbeam 2, and the rollers 11 are mounted on the guide rod 12. A vertically arranged central gear 16 is also installed between the two crossbeams 2, and racks 18 are respectively installed on the roller mounting seats 17. The two racks 18 are staggered and mesh with the central gear 16 respectively. When the clamping cylinder 10 extends or retracts, it drives the clamping support to move, causing the roller mounting seats and racks to move along the guide rods. Then, the central gear rotates, driving the other rack to move. This achieves synchronous movement of the two clamping supports, and the meshing of the central gear and rack improves positioning accuracy.

[0020] A heat insulation cover 9 is installed on the crossbeam unit, and heat insulation covers 9 are respectively installed between the clamping side of the clamping block and between the two support beams 3. The rolling plate is supported on the heat insulation cover.

[0021] Multiple detection units are symmetrically arranged on the outer side of the frame, and the detection units correspond to the clamping units. Each detection unit includes a detection fixing block 13, on which a vertically arranged detection frame 14 is set. The detection frame 14 is equipped with a detection switch, which is signal-connected to the clamping cylinder 10. The detection switch is used to detect whether the material is in place, thereby controlling the operation of the clamping cylinder.

[0022] This application features a compact structure and convenient operation. By cooperating with the clamping cylinder and the synchronous guiding mechanism, the two clamping blocks can clamp the rolling plate synchronously, achieving equal thrust on both sides of the rolling plate, avoiding rolling plate displacement, and improving positioning accuracy and sawing quality.

[0023] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
