Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a small laser cutting machine with a front and rear independent tooling. Background Technique

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and holes are formed by evaporation. As the beam moves relative to the material, the holes continuously form a very narrow slit, completing the cutting of the material. With the development of the laser cutting industry for decades, the cutting process has become more and more advanced, and the requirements for cutting efficiency are getting higher and higher. The development of laser cutting machines is also getting faster and faster. Laser cutting machines are realized by using the high-power density energy generated after laser focusing. Under the control of a computer, the laser is discharged by a pulse, so as to output a controlled repetitive high-frequency pulsed laser, forming a beam with a certain frequency and a certain pulse width. The pulsed laser beam is conducted and reflected through the optical path and focused on the surface of the workpiece to be processed through a focusing lens group, forming a series of fine, high-energy density light spots. The focal spot is located near the surface to be processed, instantaneously melting or vaporizing the material to be processed at a high temperature. Each high-energy laser pulse instantaneously splashes out a small hole on the surface of the object. Under the control of a computer, the laser processing head and the material to be processed perform continuous relative movement to dot according to a pre-drawn pattern, so that the object can be processed into the desired shape.

[0003] However, the traditional laser cutting machine cannot meet the needs of people, and it has the following defects: First, it is not designed with a double-station structure. For the traditional device, only a single station is used for cutting. When manual loading is carried out, the device needs to wait, resulting in a large amount of time waste, and the cutting efficiency of the single station is relatively low, unable to meet the needs of users; Second, it is not designed with a dust treatment device. During the operation of the device, some dust will be generated, which will cause certain harm to the environment and physical health, and may block the line of sight and cause work hazards, and cannot well ensure the safety of the staff.
