混合穿孔对输送带的影响有哪些?

输送带厂家多次表示输送带的混合穿孔过程对输送带的影响,并通过百度正式发布了输送带的要点:
The conveyor belt manufacturer has repeatedly expressed the impact of the mixed perforation process of the conveyor belt on the conveyor belt, and officially released the key points of the conveyor belt through Baidu:
(1)爆破钻孔:输送带材料在连续激光照射下,在中间形成一个坑,再与激光束同轴氧流,迅速将熔融材料去除,形成一个孔。孔的大小与板的厚度,平均直径的爆破穿孔金属板厚度的一半,所以厚板爆破穿孔的孔直径较大,而不是圆的,不应该被用于要求较高的零件(如石油筛缝管),只能使用上的浪费。此外,由于在射孔中使用的氧气压力与切割时相同,所以飞溅更大。
(1) blasting drilling: under the continuous laser irradiation, the conveyor belt material forms a pit in the middle, and then flows with the coaxial oxygen of the laser beam to quickly remove the molten material and form a hole. The hole size and the thickness of the plate, half of the thickness of the metal plate with the average diameter of the blasting perforation, so the hole diameter of the thick plate blasting perforation is larger, rather than round, should not be used for the parts with higher requirements (such as the petroleum screen seam pipe), and can only be used for waste. In addition, since the oxygen pressure used in perforating is the same as that used in cutting, the spatter is larger.
(2)脉冲钻削:利用脉冲激光峰值功率熔化或蒸发少量材料。空气或氮气常作为辅助气体使用,以减少放热氧化引起的孔洞膨胀。切割时气体压力低于氧气压力。激光的每一个脉冲只产生一个小的粒子喷雾,这些粒子逐渐渗透,所以穿孔板需要几秒钟的时间。
(2) pulse drilling: use the peak power of pulse laser to melt or evaporate a small amount of materials. Air or nitrogen is often used as auxiliary gas to reduce the hole expansion caused by exothermic oxidation. Gas pressure is lower than oxygen pressure during cutting. Each pulse of the laser produces only a small particle spray, which gradually penetrates, so the perforation plate takes several seconds.

一旦输送带穿孔,辅助气体被氧气代替进行切割。射孔质量优于爆破射孔。用于此目的的激光器不仅要有更高的输出功率;更重要的是光束的时间和空间特性,所以一般的横流CO2激光器不能满足激光切割的要求。此外,脉冲射孔需要更可靠的气路控制系统,实现对气体类型、气体压力和射孔时间的控制。
Once the conveyor belt is perforated, the auxiliary gas is cut by oxygen instead. Perforating quality is better than blasting perforating. The laser used for this purpose should not only have higher output power, but also the time and space characteristics of the beam, so the general cross flow CO2 laser can not meet the requirements of laser cutting. In addition, a more reliable gas path control system is needed to realize the control of gas type, gas pressure and perforation time.
