A kind of sheet metal laser cutting equipment

Abstract

The invention discloses a plate laser cutting equipment, the structure of which comprises a beam, a cabinet, an operating platform, a laser, a longitudinal beam, and a plate placement structure. The cabinet is installed between the beams and welded together. The beam is installed horizontally on the upper end of the beam and adopts movable connection, the laser is set on the upper end of the longitudinal beam, and the plate placement structure is installed horizontally between the beams; the plate placement structure includes a frame, an air guide structure, an inner air cavity, a plate fixing structure, and a fan. The air guide structure is installed horizontally on the bottom inside the frame, the inner air cavity is set on the inside of the frame, the plate fixing structure is installed horizontally on the upper end of the frame, and the fans are installed on both sides of the frame. The present invention sets a plate fixing structure above the air guide structure , so that while cooling the cutting part, it will bring out the irritating smell to the outside together, thereby preventing the wooden board from being ignited, preventing the shape from changing, and improving the quality of the cut board.

Description

technical field [0001] The invention belongs to the field of laser cutting, and in particular relates to a plate laser cutting device. Background technique [0002] In the past, people usually used the high-speed rotation of the blade to cut the plate, and the blade was moved to complete the cutting and separation, but cutting in this way produced a large amount of dust, so the plate laser cutting equipment was derived, mainly using the high-speed The laser beam with high power density irradiates the plate, causing holes to appear in the plate, and then moves the beam to achieve relative mobile cutting, so that the continuous holes will form slits to achieve cutting, reducing the generation of dust, but the existing technology has the following shortcomings: [0003] Due to the low ignition point of wooden boards, and the temperature generated by the laser beam of laser cutting equipment is much higher than the ignition point of wooden boards, it will ignite wooden boards wh...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a laser cutting equipment for boards to solve the problem that the ignition point of wood boards is low in the prior art, and the temperature generated by the laser beam of the laser cutting equipment is much higher than the ignition point of wood boards. When laser cutting produces a pungent smell, it will ignite the wooden board, causing the shape of the wooden board to change, thereby affecting the overall shape of the cut board
