Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinet shell processing, and in particular to a laser cutting device for electrical cabinet shell processing. Background Art

[0002] The electrical cabinet housing is an external structure used to protect electrical equipment and circuits. It is usually made of strong materials to prevent the external environment from affecting the internal electrical components, while providing a certain degree of safety protection to prevent people from contacting dangerous electrical parts.

[0003] Laser cutting technology is usually used for the processing of electrical cabinet shells, especially the cutting of its metal parts (such as cold-rolled steel, stainless steel, aluminum alloy, etc.). This is because laser cutting can provide high-precision and high-efficiency processing, especially when dealing with complex shapes and details.

[0004] Laser cutting is a processing method that uses a high-energy laser beam to focus on the surface of the material, and melts, evaporates, ablates or gasifies the material through instantaneous heating, thereby achieving cutting. Its main principle is to locally heat the material to the melting point or gasification point through a high-power laser beam, and use gas assistance (such as oxygen, nitrogen or air) to blow away the molten material to complete the cutting.

[0005] When using existing laser cutting equipment, if the cutting speed is too slow, the laser will work for too long per unit time, which may cause the cutting to be too deep or burn through the material. The pressure of the auxiliary gas used will also affect the cutting effect. If the gas pressure is too high, it may cause too much laser energy to be directed under the material, causing penetration.

The clean aluminum foil can better reflect the laser heat and prevent the heat generated during the cutting process from being excessively transferred to the bottom of the material, thereby reducing overcutting. By cleaning the dirt on the surface of the aluminum foil, its reflective performance can be prevented from decreasing, thereby extending the service life of the aluminum foil.

[0038] Working principle: when the electric cabinet housing 6 needs to be laser cut, the electric cabinet housing 6 is placed on the placement seat 2, and then the hydraulic rod 102 is used to drive the placement seat 2 to move up, so that the electric cabinet housing 6 is placed in a suitable position, and then the electric push rod 103 is used to drive the adjustment frame 3 to move, so that the overcut protection mechanism 5 is inserted into the electric cabinet housing 6 and is located below the cutting surface of the electric cabinet housing 6;

[0039] Then, the overcut protection mechanism 5 is adjusted according to the cutting size, and the motor 301 is used to drive the bidirectional screw rod 302 to rotate, so that the bidirectional screw rod 302 drives the moving frame 4 to move, so that the gear 505 on the retractable tube 502 is meshed with the rack 303, thereby driving the retractable tube 502 to rotate, so that the silicone curtain 501 is unfolded.
