Description

Technical Field

[0001] This utility model relates to the field of plate cutting equipment technology, specifically to a plate cutting circle device. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] Cutting boards into circular shapes is a common requirement in board processing. While patent CN218081530U can fix the board for circular cutting, the board is prone to deviation, resulting in poor processing accuracy and stability. Simple contour cutting relies on manual cutting along the edge of a standard circular board, which is prone to large errors and low efficiency. Small band saws are prone to tearing wood fibers when cutting circles, and punch-shear cutting is inefficient and causes rapid die wear.

[0004] In addition, there are some complex intelligent devices, including five-axis linkage equipment, such as the rotary cutting device for aluminum processing with publication number CN202311191869.4. Although it can achieve complex trajectory cutting, it requires professional technicians to program the code, and ordinary workers need to be trained for a long time before they can operate it independently, and the cost is high.

[0005] The shortcomings of the existing technology mentioned above seriously affect the quality, efficiency, and economy of cutting sheet metal into circles, and there is an urgent need for a new type of equipment to solve these problems. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a sheet metal rounding device, aiming to improve the quality and efficiency of sheet metal rounding and reduce production costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A sheet metal rounding device includes a workbench, a crossbeam above the workbench, and a first mounting plate and a second mounting plate slidably mounted on the front side of the crossbeam. An upper cutting blade assembly and a lower cutting blade assembly are vertically slidably mounted on the first mounting plate. The upper cutting blade assembly and the lower cutting blade assembly are provided with an upper blade and a lower blade arranged opposite to each other. A first scale is also provided in the same vertical plane where the upper and lower blades are located to maintain synchronous movement. The first scale is used to limit the first calibration edge of the rectangular raw material plate. The second mounting plate is equipped with a pressing clamping device, and the telescopic end of the pressing clamping device is provided with a rotatable pressure plate; A rotary table is provided on the workbench, which is used to cooperate with the downward clamping device to clamp the rectangular raw material plate and drive the rectangular raw material plate to rotate. A longitudinal beam is also provided on the rear side of the crossbeam, and a second calibration ruler is installed on the longitudinal beam for limiting the second calibration edge of the rectangular raw material plate. The first calibration edge and the second calibration edge are a set of adjacent right-angled edges of the rectangular raw material plate.

[0008] Preferably, the crossbeam is provided with a first slide rail and a second slide rail for slidingly mounting the first mounting plate and the second mounting plate; The first mounting plate is equipped with a third slide rail and a fourth slide rail, and a first mounting base and a second mounting base for mounting the upper cutter assembly and the lower cutter assembly are slidably mounted on the third slide rail and the fourth slide rail, respectively.

[0009] Preferably, the upper blade and the lower blade are respectively mounted on one end of the corresponding rotating shaft, the rotating shaft is rotatably mounted in the corresponding fixed cylinder, and the other end of the rotating shaft is connected to the output end of the corresponding cutting power device. The cutting power device is respectively mounted on the corresponding first mounting base or second mounting base.

[0010] Preferably, the first scale is mounted and fixed on the first mounting plate, the first mounting base, or the second mounting base.

[0011] Preferably, the first mounting plate and the second mounting plate are driven to slide by a first lead screw assembly and a second lead screw assembly mounted on the crossbeam, respectively. The first mounting base and the second mounting base are driven to slide by the third lead screw assembly and the fourth lead screw assembly mounted on the first mounting plate, respectively.

[0012] Preferably, a bearing seat is installed on the upper side of the pressure plate, and the telescopic end of the downward clamping device is fixed in the bearing seat by means of a bearing.

[0013] This utility model has at least the following beneficial effects: In this invention, a first calibration ruler limits the first calibration side of the rectangular raw material plate, and a second calibration ruler limits the second calibration side, thereby positioning a set of adjacent right-angled sides of the rectangular raw material plate. Since the first and second calibration sides are right-angled sides, the positioning reference is clear and stable, ensuring the accurate initial position of the rectangular raw material plate before rotary cutting and avoiding the problem of deviation during the plate positioning process in traditional equipment.

[0014] Meanwhile, this utility model adopts a "top-bottom cutting" design with an upper cutting blade assembly and a lower cutting blade assembly, with the upper and lower blades cutting simultaneously from both sides of the material. Compared with the problem of traditional unidirectional cutting which easily leads to tearing of the material, this bidirectional synchronous cutting can balance the cutting force, reduce the deformation or burrs caused by the force on one side of the material, and reduce the trajectory deviation caused by excessive resistance of the cutting blade, further ensuring the roundness accuracy and better adapting to different thickness requirements.

[0015] In addition, the operation process of this utility model only requires placing the plate, aligning with the ruler, clamping, and starting the rotary cutting. Ordinary workers can operate it independently without long-term training, which solves the problems of high operating threshold and high training cost of traditional complex equipment.

Specifically, a bearing seat 412 is mounted on the upper side of the pressure plate 410, and the telescopic end of the downward clamping device 411 is fixedly installed within the bearing seat 412 via a bearing. The downward clamping device 411 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, etc.

[0024] A longitudinal beam 600 is also provided on the rear side of the crossbeam 200. A second calibration ruler 610 for limiting the second calibration edge of the rectangular raw material plate is installed on the longitudinal beam 600. The first calibration edge and the second calibration edge are a set of adjacent right-angled edges of the rectangular raw material plate.

[0025] The working method and process of this device are as follows: The upper and lower blades begin cutting from one of the right-angled sides of the rectangular raw material plate. The cutting method involves keeping the cutter stationary while the raw material plate rotates one full revolution. Specifically, the upper and lower blades simultaneously cut the upper and lower sides of the rectangular raw material plate.

[0026] After placing the rectangular raw material plate on the rotary table 500, first align the first calibration ruler 330 and the second calibration ruler 610 to ensure the rectangular raw material plate is positioned. Then, the second mounting plate 400 drives the downward clamping device 411 to slide above the rotary table 500, and its telescopic end begins to press down to clamp and fix the rectangular raw material plate. Then, the rotary table begins to drive the rectangular raw material plate to rotate and start cutting.
