合肥钣金加工浅谈外光路系统的影响因素对切割质量的影响
 

激光器发出的原始光通过外光路系统(包括反射和透射)传输,在极高的功率密度下准确地照射到工件表面。对光学元件的系统应定期检查,及时调整,确保当割炬在工件上方运行时,光束适当地转移到透镜的中心,并聚焦到很小的光斑内,高质量的切割工件。一旦光学元件发生变化或受到污染,切割质量就会受到影响,甚至无法进行切割。

外光路透镜被气流中的杂质污染,切割区的飞溅、透镜的粘结或冷却不足会导致镜头过热,影响光束的能量传输。使光路准直漂移造成严重后果,透镜过热也会引起焦点畸变,甚至危及镜头本身。一旦光学元件被污染,甚至粘附在切割产品的小颗粒上,清洗是一个非常重要且常常被忽视的问题。下面列出了一些清洁点:


(1)镜头清洁:清洁镜头纸折成几折,用几滴纯丙酮浸泡;轻轻擦拭镜头表面湿镜头纸,镜头不注意手指的压力;重复几次,直到镜片表面的清洁,在镜子里无污垢和残留的痕迹;干空气干燥;必要的你可以用几滴丙酮湿纸到透镜,轻轻擦洗镜片的表面,去除重污垢滴。重要的是要注意,丙酮吸收空气中的水分和水分,污染丙酮本身。因此,重要的是要保持丙酮瓶紧闭,决不倒入剩余的丙酮溶液回到新的丙酮瓶。

(2)清洗镜片:从框架上拆卸镜头;镜子上,镜子上的镜头纸;在镜头纸上滴几滴丙酮,轻轻地拉了一个镜片纸;重复上述过程,直到镜子擦干净,无灰尘和污渍,在镜子的镜头;在镜座。如果你用钼镜做反光镜,因为它不能电镀,抛光后可以直接使用,可以用水(肥皂、水或含洗涤剂的水)清洗。然而,其他表面涂层的镜片不能用水清洗,因为许多涂层溶解在水中,镜片就会损坏。




The original light emitted by the laser is transmitted through the outer optical path system (including reflection and transmission), which is accurately irradiated to the surface of the workpiece at a very high power density. The optical component of the system should be checked regularly, timely adjustments to ensure that when the cutting torch above the workpiece when running the beam properly transferred to the center of the lens and focused into a very small spot, high quality cutting of workpiece. Once any of the optical components are changed or contaminated, the quality of the cutting will be affected and even the cutting cannot be carried out.
The outer light path lens is polluted by impurities in the airflow, and the spatter of the cutting zone, the particle bonding or the insufficient cooling of the lens can cause overheating of the lens and influence the energy transmission of the beam. Causes the light path collimation drift to bring about the serious consequence, the lens overheating can also cause the focus distortion, even endangers the lens itself.
Once the optical components are contaminated and even stuck to the small particles of the cutting product, cleaning is a very important and often neglected problem. Some cleaning points are listed below:
(1) lens cleaning: clean the lens paper bent into several fold, with a few drops of pure acetone soaked; gently wipe the lens surface wet lens paper, lens can't note finger pressure; repeated several times, until the lens surface clean, no dirt and residual traces in the mirror; dry air drying; necessary you can use a few drops of acetone wet paper into rod lens, gently scrub the surface of the lens, to remove the heavy dirt drops.
It is important to note that acetone absorbs moisture and moisture from the air, polluting the acetone itself. Therefore, it is important to keep the acetone bottle tightly closed and never pour the remaining acetone solution back into the new acetone bottle.
(2) cleaning mirror lens: remove the lens from the frame; the mirror upward, the lens paper on the mirror; in the lens paper a few drops of acetone, and gently pull up a mirror lens paper; repeat the above process until the mirror clean, no dirt and stains in the mirror to the lens; in the mirror seat.
If you use a molybdenum mirror as a reflector, because it can not be plated, and can be used directly after polishing, it can be cleaned with water (soap, water or water containing detergent). However, other surface coated lenses can not be cleaned with water, because many of the coating dissolved in water, the lens will be damaged.
