Description
Technical Field
The invention relates to the field of cutting machines, in particular to a plate laser cutting machine for producing power equipment.
Background
The production of power equipment needs to use a large amount of materials such as metal plates, in order to meet the application requirements under different conditions, different plates need to be cut, the efficient and environment-friendly cutting device in the cutting operation is a laser cutting machine, and the laser cutting machine focuses laser emitted from a laser into laser beams with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach a melting point or a boiling point, and simultaneously, the high-pressure gas coaxial with the laser beam blows away the molten or gasified metal. And finally, the material is cut along with the movement of the relative position of the light beam and the workpiece, so that the cutting purpose is achieved.
The laser cutting processing replaces the traditional mechanical knife with invisible light beams, has the characteristics of high precision, quick cutting, smooth cut, low processing cost and the like, and can gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser tool bit is not in contact with the workpiece, so that the surface of the workpiece cannot be scratched in the working process; the laser cutting speed is high, the cut is smooth and flat, and subsequent processing is generally not needed; the cutting heat affected zone is small, the deformation of the plate is small, and the cutting seam is narrow (0.1 mm-0.3 mm); the notch has no mechanical stress and no shearing burr; the processing precision is high, the repeatability is good, and the surface of the material is not damaged; the numerical control programming can be used for processing any plan, the whole board with large breadth can be cut, a die does not need to be opened, and the method is economical and time-saving.
At present, due to the manufacturing cost and other reasons, the laser generator emits laser beams with a certain divergence angle and in a conical shape. When the height of the "cone" is changed (corresponding to the change in the optical path length of the laser cutter), the beam cross-sectional area of the focusing lens surface is changed. In addition, the light also has wave-like properties, and therefore, it is inevitable to have diffraction phenomena that cause the beam to expand laterally during propagation, which phenomena are present in all optical systems and can determine the theoretical limit values of these systems in terms of performance. Due to the "cone" shape of the gaussian beam and the diffraction effect of the optical wave, when the optical path length changes, the diameter of the beam acting on the lens surface changes all the time, which causes the size and depth of focus to change, but has little effect on the position of the focus. If the size and depth of focus are changed in continuous processing, the processing is inevitably affected greatly, for example, the width of a cutting seam is inconsistent, the plate can be cut or ablated under the same cutting power, and the like.
In summary, the existing laser cutting device has the following defects:
(1) although the cutter can realize continuous cutting of a workpiece to be processed, the device does not have a zooming function, so that the focus and the spot size of an output light beam cannot be adjusted according to needs for the workpiece with a large thickness difference, and the cutting efficiency is low;
(2) although the device has the position of the probe adjusted by the bearings in three directions, the adjustment is carried out by the rotation of the screw rod, the precision is limited and the stability is poor.
