At the beginning, the laser cutting machine manufacturer’s laser tube cutting machine mainly relied on manual focus adjustment. With the continuous development of laser technology, manual focus will eventually be eliminated and replaced by auto focus. A high-power laser tube cutting machine effectively has an auto-focusing function. However, some people will say that the light path is integrated in the cutting head, we can’t simply change the height of the cutting head? When the cutting head is up, focus on the high position, and when the cutting head is down, focus on the low position. However, it turns out that it is not that simple.
The laser pipe cutting machine of the laser cutting machine manufacturer has a nozzle at the bottom of the cutting head. During the cutting process, the distance between the nozzle and the workpiece (nozzle height) is about 0.5-1.5 mm, which can be regarded as a fixed value, that is, the nozzle height does not change, so it is impossible to achieve focusing by lifting the laser head.
The focal length of the focusing lens is constant, so it is not realistic to change the focal length of the focal point. Changing the position of the focusing lens will correspondingly change the main social focus position: if the focusing lens drops, the focus will go down; when the focusing lens rises, the focus will go up. This is indeed such a way of focusing. Students use a control motor technology to drive the focusing lens to move up and down, which can automatically adjust the focus through the realization of information.
The laser cutting machine manufacturer’s laser tube cutting machine uses another method for auto-focusing: the front beam enters the focusing lens and is placed on a variable curvature mirror (or adjustable mirror), and the divergence angle of the reflected beam is changed. The focal position of the curvature of the mirror. With the system’s automatic focusing function, when processing enterprises with different learning materials and different thickness workpieces, the machine equipment can automatically and quickly adjust the focus to the appropriate position through the numerical control at the same time. Therefore, it is possible to achieve a significant level of improvement in the processing and production efficiency of the laser pipe cutting machine, and it can also be developed to greatly reduce the perforation time of the thick plate.
Therefore, the automatic focusing function is an indispensable and important function of the laser pipe cutting machine of the laser cutting machine manufacturer.
