Abstract
Description
Technical Field
[0001] The utility model relates to the field of laser cutting equipment, in particular to a laser cutting machine head component and a laser cutting machine. Background Art
[0002] Laser drilling technology is one of the key technologies in the field of modern manufacturing. It utilizes the high energy density characteristics of the laser beam and focuses it as a high-intensity heat source to heat the material, causing the material in the laser action area to melt or vaporize and then evaporate, thereby forming holes.
[0003] Laser drilling has many advantages. First, it has high precision, and the processed aperture size and density are consistent, which is very suitable for high-end and refined drilling needs. Secondly, laser drilling is not limited by the properties of the material, and can be used to process soft, hard, and brittle materials. Furthermore, laser drilling is a non-contact processing method that does not produce mechanical indentations, nor does it deform or break the material. The processed holes are smooth and burr-free. In addition, the entire laser drilling process is automated and does not require manual operation, which greatly improves production efficiency and reduces labor costs.
[0004] For the processing of threaded holes, drilling is usually done first, followed by tapping. The drilling process can also be achieved through laser drilling. In terms of equipment, the laser cutting machine and tapping equipment used for drilling are relatively independent, and the plate needs to be transferred to the tapping equipment after drilling. However, laser processing uses the high temperature of the laser to melt the plate. After the plate is cooled from this high temperature, the metal material at the drilling position may harden, which increases the difficulty of tapping. Summary of the invention
