Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing, and in particular to a metal sheet cutting device. Background Technology

[0002] Metal sheets are products made of various metal materials and are widely used in many industries such as construction and manufacturing. These sheets can be made from different metals or alloys. In the metal processing industry, the cutting of metal sheets is a common but crucial process. With industrial development and technological progress, higher requirements have been placed on the precision, efficiency and quality of metal sheet cutting.

[0003] Current metal sheet cutting methods typically involve fixing the metal sheet to a cutting device and then using a laser cutter to cut it. However, current laser cutters have limitations in cutting thickness, making it difficult to completely cut thick sheets in one go. After the initial cut, the cutting device needs to be stopped, and the metal sheet needs to be manually flipped for cutting on the other side. This process is complex, time-consuming, and labor-intensive, easily affecting cutting efficiency and quality, and is very inconvenient to use.

[0004] Therefore, it is necessary to design a metal sheet cutting device that can automatically fix and flip metal sheets of different thicknesses for double-sided cutting, to prevent thicker metal sheets from being left uncut, improve cutting efficiency and quality, and provide a flexible and convenient metal sheet cutting device. Utility Model Content

[0005] To overcome the limitations of current laser cutters in cutting thickness, which makes it difficult to completely cut thick plates in one go, and the need to stop the cutting equipment after single-sided cutting and manually flip the metal plate to cut the other side, which is complicated, time-consuming, and labor-intensive, and easily affects the efficiency and quality of cutting, this utility model provides a metal plate cutting device that can automatically fix and flip metal plates of different thicknesses for double-sided cutting, preventing thicker metal plates from being left uncut, improving cutting efficiency and quality, and offering flexibility and convenience.

[0006] The technical solution is as follows: A metal sheet cutting device includes a cutting table, a metal grid, an electric push rod, a flipping component, and a cutting component. The upper side of the cutting table is connected to the metal grid, and the upper sides of both the left and right sides of the cutting table are connected to the electric push rod. The electric push rod is equipped with a flipping component for fixing and flipping the sheet, and the cutting table is equipped with a cutting component for cutting the sheet.

[0007] Furthermore, the metal grating has multiple discharge ports.

[0008] Furthermore, the flipping assembly includes a rotary joint, a photoelectric sensor, a first motor, clamping plates, screws, and a metal plate body. Each extension end of the electric push rod is equipped with a connecting plate, and each connecting plate is rotatably connected to a rotary joint. Photoelectric sensors are connected to both the upper and lower sides of the rotary joint, and these sensors are electrically connected to the electric push rod on the same side. The upper side of the left connecting plate is connected to the first motor, and the output shaft of the first motor is connected to the left rotary joint. Clamping plates are connected to the sides of the rotary joints that are close to each other. Screws are threaded onto both the front and rear sides of the clamping plates. A metal plate body is placed between the clamping plates, and the screws are in contact with the metal plate body, which in turn contacts the metal grid.

[0009] Furthermore, all the clamps are U-shaped.

[0010] Furthermore, the nuts on the screws are all hexagonal.

[0011] Furthermore, the cutting assembly includes a first lead screw, a second motor, a transmission support column, a third motor, and a laser cutter. The first lead screw is rotatably connected to the upper rear of the cutting table, and the second motor is connected to the left rear of the cutting table. The output shaft of the second motor is connected to the first lead screw. The transmission support column is threadedly connected to the first lead screw and is slidably connected to the cutting table. The second lead screw is rotatably connected to the upper part of the transmission support column, and the third motor is connected to the rear upper part of the transmission support column. The output shaft of the third motor is connected to the second lead screw. A slider is threadedly provided on the second lead screw, and the slider contacts and engages with the transmission support column. The laser cutter is connected to the lower side of the slider.

[0012] This utility model has the following advantages: 1. By fixing the metal sheet to the clamp, adjusting the height of the sheet by moving the connecting plate, turning the metal sheet over by rotating the rotary joint, and cutting the metal sheet on both sides by moving the transmission support column and the laser cutter, this utility model can automatically fix and turn over metal sheets of different thicknesses for double-sided cutting, preventing thicker metal sheets from being left uncut, improving cutting efficiency and quality, and making it flexible and convenient to use.

[0013] 2. In this invention, after the metal sheet is flipped over, the electric push rod reverses its operation, causing the metal sheet body to move and reset. When the photoelectric sensor detects that the distance to the cutting table is too close, the electric push rod is automatically turned off, causing the metal sheet to stop descending. This allows the electric push rod to be automatically turned off and stopped when the distance to the metal sheet body is detected to be too close during the flipping and descent, preventing collision damage between the sheet and the equipment and improving the safety of use.

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 protection scope of the present utility model.

[0020] A metal sheet cutting device, such as Figures 1-4As shown, the assembly includes a cutting table 1, a metal grid 2, an electric push rod 3, a flipping assembly, and a cutting assembly. The metal grid 2 is connected to the upper side of the cutting table 1, and the metal grid 2 has multiple discharge ports to facilitate the discharge of debris. The electric push rod 3 is connected to the upper sides of both the left and right sides of the cutting table 1. The electric push rod 3 is equipped with a flipping assembly for fixing and flipping the sheet material. The flipping assembly includes a rotary joint 4, a photoelectric sensor 41, a first motor 5, a clamping plate 6, screws 7, and a metal sheet body 8. The telescopic ends of the electric push rod 3 are equipped with connecting plates. The rotary joint 4 is rotatably connected to the top of each rotary joint 4. Photoelectric sensors 41 are connected to both the upper and lower sides of each rotary joint 4. Each photoelectric sensor 41 is electrically connected to the electric push rod 3 on the same side. The first motor 5 is connected to the upper side of the connecting plate on the left. The output shaft of the first motor 5 is connected to the rotary joint 4 on the left side. Clamping plates 6 are connected to the adjacent sides of each rotary joint 4. Screws 7 are threaded onto both the front and rear of each clamping plate 6. The nuts on the screws 7 are hexagonal. The metal plate is placed between the clamping plates 6. The metal sheet body 8 and the clamping plates 6 are all U-shaped to facilitate the placement of the metal sheet body 8. The screws 7 are all in contact with the metal sheet body 8, which in turn contacts the metal grid 2. The cutting table 1 is equipped with a cutting assembly for cutting the sheet metal. The cutting assembly includes a first lead screw 9, a second motor 10, a transmission support column 11, a second lead screw 12, a third motor 13, and a laser cutter 14. The first lead screw 9 is rotatably connected to the upper rear of the cutting table 1, and the second motor 10 is connected to the left rear of the cutting table 1. The output shaft of 0 is connected to the first lead screw 9. The first lead screw 9 is connected to the transmission support column 11 by a thread. The transmission support column 11 is slidably connected to the cutting table 1. The upper part of the transmission support column 11 is rotatably connected to the second lead screw 12. The upper rear side of the transmission support column 11 is connected to the third motor 13. The output shaft of the third motor 13 is connected to the second lead screw 12. The second lead screw 12 is provided with a slider by a thread. The slider is in contact with the transmission support column 11. The lower side of the slider is connected to the laser cutter 14.

[0021] When it is necessary to cut metal sheets, this device can be used. The cutting table 1 is brought into contact with the ground, and then the metal sheet body 8 is brought into contact with the clamping plate 6. The clamping plates 6 are all U-shaped to facilitate the placement of the metal sheet body 8. The metal sheet body 8 is then pushed to move, so that it is placed on the clamping plate 6, making it contact with the metal grid 2. Then, the screws 7 are rotated to move and contact the metal sheet body 8 for fixation. The nuts on the screws 7 are all hexagonal. Next, according to the cutting requirements, the second motor 10 is started. The second motor 10 drives the first lead screw 9 to rotate, and under the action of the thread, the transmission support column 11 moves, thus... The second lead screw 12 and the laser cutter 14 move to a suitable position, then the motor is turned off, and the third motor 13 and the laser cutter 14 are started. The third motor 13 drives the second lead screw 12 to rotate, causing the slider to move under the action of the thread, which in turn causes the laser cutter 14 to move and cut the metal sheet body 8. When the metal sheet body 8 is thick, after cutting one side of the metal sheet body 8 through the above operation, the second motor 10 operates in reverse, causing the first lead screw 9 to rotate in reverse. Under the action of the thread, the transmission support column 11 moves in reverse to reset, causing the second lead screw 12 and the laser cutter 14 to move in reverse to reset, and then the operation is started. The electric push rod 3 moves the connecting plate, causing the rotary joint 4, the photoelectric sensor 41, the clamping plate 6, and the metal sheet body 8 to move. Once the plate reaches a suitable height, the first motor 5 is activated, driving the left rotary joint 4 to rotate, causing the clamping plate 6 and the metal sheet body 8 to rotate. This, in turn, causes the right rotary joint 4 to rotate, flipping the metal sheet body 8. After flipping, the first motor 5 is turned off, and the electric push rod 3 reverses its operation, causing the rotary joint 4, clamping plate 6, and metal sheet body 8 to move back to their original positions. When the photoelectric sensor 41 detects that it is too close to the cutting table 1, it automatically shuts off the circuit. The electric push rod 3 stops the descent of the metal sheet body 8. This allows the push rod to automatically stop descent when it detects a close proximity during the flipping and descent of the metal sheet body 8, preventing collision damage to the sheet and equipment and improving safety. Then, the second motor 10 is activated, driving the first lead screw 9 to rotate. Under the action of the thread, the transmission support column 11 moves, causing the second lead screw 12 and the laser cutter 14 to move to their original positions. Next, the third motor 13 operates in the opposite direction, causing the second lead screw 12 to rotate in the opposite direction. Under the action of the thread, the slider moves in the opposite direction to reset, causing the laser cutter 14 to move in the opposite direction to cut the metal sheet body 8.The metal sheet body 8 is then cut, enabling automatic fixing and flipping of metal sheets of different thicknesses for double-sided cutting. This prevents thicker metal sheets from being left uncut, improving cutting efficiency and quality. It is flexible and convenient to use. During the cutting process, the cutting debris falls onto the metal grid 2 and is collected from the discharge port. After cutting, the third motor 13 and the laser cutter 14 are turned off. Then, the second motor 10 operates in reverse, causing the first lead screw 9 to rotate in the opposite direction. Under the action of the thread, the transmission support column 11 moves in the opposite direction to reset, causing the second lead screw 12 and the laser cutter 14 to move in the opposite direction to reset. Then, the second motor 10 is turned off, and the screw 7 is rotated in the opposite direction to disengage from the metal sheet body 8. The metal sheet body 8 can then be removed.
