DETAILED DESCRIPTION

[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0020] Example: Through the personnel in this field, all electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0021] See also Figure 1-4 In order to solve the problem that the metal sheet cutting equipment lacks a positioning function, the worker needs to rely on the naked eye to align the part of the metal sheet to be cut with the cutting wheel, which easily leads to a deviation between the cutting wheel and the part of the metal sheet to be cut, affecting the cutting quality and resulting in low cutting efficiency, this technical solution is designed. The detailed technical solution is as follows;

[0022] A metal sheet cutting device comprises a base 1, a door frame 2 is mounted on the wall of the base 1, a clamping structure is mounted on the base 1, a cutting structure is mounted on the door frame 2, and a waste collection structure is also provided on the base 1;

[0023] Specifically, the clamping structure includes a U-shaped frame 3 with an upward opening. A first hydraulic cylinder 4 is inserted into the side wall of the U-shaped frame 3. The telescopic end of the first hydraulic cylinder 4 is located inside the U-shaped frame 3. A pressure plate 5 is installed at the telescopic end of the first hydraulic cylinder 4. A connecting frame 6 is also installed on the side wall of the U-shaped frame 3. A line laser 7 is installed at one end of the connecting frame 6. The line laser 7 is located outside one end of the U-shaped frame 3.

[0024] It should be noted that the U-shaped frame 3 is used to place the metal thick plate longitudinally. The straight line laser 7 works to project a vertical line, and the part of the metal thick plate to be cut is moved to coincide with the vertical line. Then, the first hydraulic cylinder 4 is controlled to extend, so that the pressing plate 5 and the U-shaped frame 3 clamp the metal thick plate to achieve the fixation of the metal thick plate.

[0025] Specifically, the cutting structure includes a second hydraulic cylinder 8, which is inserted into the portal frame 2. The telescopic end of the second hydraulic cylinder 8 is installed with a mounting shell 9, and a motor 10 is installed inside the mounting shell 9. The driving end of the motor 10 is installed with a rotating shaft 11, which is movably inserted into the mounting shell 9. A cutting disc 12 is installed at one end of the rotating shaft 11, and the cutting disc 12 is installed corresponding to the line laser 7.

[0026] It should be noted that the position where the vertical line is located is the position corresponding to the cutting disc 12. When the motor 10 is working, the driving end of the motor 10 drives the rotating shaft 11 to rotate on the mounting shell 9, and the cutting disc 12 rotates accordingly. The second hydraulic cylinder 8 extends to lower the cutting disc 12 until the metal thick plate is cut. Through the positioning of the straight line laser 7, the staff does not need to rely on the naked eye to align the part of the metal thick plate to be cut with the cutting disc 12, thereby ensuring the accuracy of the cutting position, and ensuring the cutting quality and efficiency.

[0027] Specifically, the waste collection structure includes a groove 13, which is provided on the base 1 and is aligned with the cutting disc 12. A discharge port 14 is provided on one side of the groove 13, and a cylinder 15 is installed on the other side of the groove 13. A push plate 16 is installed at the telescopic end of the cylinder 15.

[0028] It should be noted that the cut waste enters the groove 13. When the waste needs to be collected, the cylinder 15 extends, driving the push plate 16 to move. The push plate 16 pushes the waste to the discharge port 14. The operator collects the waste from the discharge port 14 to avoid close contact with the cutting disc 12 to ensure safety.

[0029] As a preferred embodiment, further, a door 17 is provided on the base 1 at a position corresponding to the discharge port 14, for shielding the discharge port 14;

[0030] As a preferred embodiment, further, the pressing plate 5 is provided with a first anti-slip groove, and the inner wall surface corresponding to the U-shaped frame 3 and the pressing plate 5 is provided with a second anti-slip groove, which is used to increase the friction between the pressing plate 5, the U-shaped frame 3 and the metal thick plate;

[0031] Preferably, further, a buffer pad 18 is installed on the inner bottom surface of the groove 13 to prevent the base 1 from being damaged when waste falls.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
