Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machine feeding, and in particular relates to a laser cutting machine feeding mechanism. Background Art

[0002] Laser cutting is the process of emitting laser light from a laser device, which is focused into a high-power-density laser beam through an optical path system. The laser beam is then irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Existing laser cutting machines require the use of feeding equipment for timely feeding during operation.

[0003] Patent number CN211102250U is a laser cutting machine feeding device that pushes the processed material through a hydraulic cylinder and a push plate. Two limiting interlayers are arranged inside the material tube to protect the processed material and avoid collision and friction between the material to be processed and the tube wall.

[0004] However, during actual feeding, only one size of the processed material can be clamped and limited, and it is difficult to accurately clamp materials of different sizes. In addition, the friction is reduced by contacting the processed material with lubricating oil. The surface of the material after cutting is stained with lubricating oil and needs to be cleaned, which makes the operation cumbersome. Utility Model Content
