二氧化碳激光切割机及速度与切割效果!

来源:www.4066.com 时间:2020-04-10 

  基本原则:
  basic principle:
  二氧化碳激光管在冬季结冰期间,如果激光管内的水不排放干净,就会导致激光管的冷却层结冰膨胀,使激光冷却层开裂。激光管不能正常工作。激光管冷却层的冻结裂纹不在包络范围内。为避免不必要的损失,请采取以下防冻措施:
  If the water in the carbon dioxide laser tube is not discharged clean in winter, the cooling layer of the laser tube will freeze and expand, and the laser cooling layer will crack. The laser tube is not working properly. The frozen crack in the cooling layer of laser tube is not within the envelope. To avoid unnecessary loss, please take the following anti freezing measures:
  1. 切断设备的所有电源
  1. Cut off all power supply of the equipment
  2. 将激光机出口处的水管拔出,将机器内部的水管和激光管排出。
  2. Pull out the water pipe at the outlet of the laser machine and discharge the water pipe and laser pipe inside the machine.
  3.将空气(压力小于0.4MP)连接到激光机进水处,彻底清洁激光机内管和激光管中的水。
  3. Connect the air (pressure less than 0.4MP) to the water inlet of the laser machine, and thoroughly clean the water in the inner tube and laser tube of the laser machine.
  4. 将冷水机或水泵取下,放置在高温的房间内,防止水循环设备结冰,以免损坏冷水机和水泵部件,给您带来不必要的麻烦;或将水从水冷却器或水泵中完全排出。
  4. Remove the chiller or water pump and place it in a high temperature room to prevent the water circulating equipment from freezing, so as to avoid damaging the components of the chiller and water pump and causing unnecessary trouble to you; or completely discharge the water from the water cooler or water pump.
  激光切割机的切割速度和切割效果:
  Cutting speed and effect of laser cutting machine:
  激光切割无毛刺,不起皱,精度高。对于许多机电制造行业来说,由于计算机程序控制的现代数控激光切割系统可以方便地切割不同形状和尺寸的工件,因此常常是多冲裁、成型工艺的;虽然激光切割机的处理速度还是慢于死,但它没有死消费,不需要修理模具,而且还节省时间更换模具,从而节约处理成本,降低生产成本,所以从整体考虑更划算。
  Laser cutting has no burr, wrinkle and high precision. For many mechanical and electrical manufacturing industries, because the modern CNC laser cutting system controlled by computer program can easily cut workpieces of different shapes and sizes, it is often the first choice of multi blanking and forming process; although the processing speed of laser cutting machine is still slower than that of death, it does not die, does not need to repair the mold, and also saves time to replace the mold, Thus, the treatment cost is saved and the production cost is reduced, so it is more cost-effective from the overall consideration.
  在工业制造系统中起着重要作用的金属加工业中,许多金属材料,无论其硬度如何,都可以用光纤切割机进行切割而不变形。然而,对于金、银、铜和铝合金等高反射性材料,激光切割是困难的,甚至是不可能的,因为它们也是良好的热导体。
  In the metal processing industry, which plays an important role in the industrial manufacturing system, many metal materials, no matter how hard they are, can be cut by optical fiber cutter without deformation. However, for highly reflective materials such as gold, silver, copper and aluminum alloy, laser cutting is difficult or even impossible, because they are also good heat conductors.
  在激光切割过程中,加入适合被切割材料的辅助蒸汽。在钢材切割过程中,氧气作为辅助蒸汽体,与熔融金属发生放热化学反应,氧化材料,同时帮助吹除切割缝内的炉渣。丙纶类塑料切割采用压缩空气、棉花、纸张等易燃材料切割采用惰性蒸汽。进入喷嘴的辅助蒸汽也冷却了聚焦透镜,防止烟灰污染透镜座内的透镜并导致其过热。激光切割机的切割速度的选择是非常重要的,可以选择的切削速度范围根据设备指令或由测试中,由于材料的厚度,材料,熔点、导热系数和表面张力的大小融化和其他因素后,切割速度也相应的变化。
  In the laser cutting process, add auxiliary steam suitable for the material to be cut. In the process of steel cutting, oxygen, as the auxiliary steam body, has exothermic chemical reaction with the molten metal, oxidizes the material, and helps to blow away the slag in the cutting seam. Polypropylene plastic cutting adopts compressed air, cotton, paper and other flammable materials cutting adopts inert steam. The auxiliary steam entering the nozzle also cools the focus lens to prevent soot from contaminating the lens in the lens holder and causing it to overheat. The selection of cutting speed of laser cutting machine is very important. The best cutting speed range can be selected according to the equipment instruction or in the test. Due to the thickness of material, melting point, thermal conductivity and surface tension melting and other factors, the cutting speed also changes accordingly.

  主要性能:
  Main performance:
  激光切割机a.适当提高切割速度可以提高切口质量,即切口略窄,切口表面更平整,减少变形。
  Laser cutting machine A. properly increasing cutting speed can improve the quality of incision, that is, the incision is slightly narrow, the incision surface is more flat, and the deformation is reduced.
  b、切割速度过快,切割线能量低于要求值。切割缝中的射流无法迅速将熔化的切割液立即吹走,造成了大量的反阻力。
  b. Cutting speed is too fast, cutting line energy is lower than the required value. The jet in the cutting seam can't blow away the molten cutting liquid immediately, which causes a lot of anti resistance.
  c,当切削速度过低,由于阳极等离子弧切割,为了维持稳定的电弧本身和阳极斑点或阳极附近区域必须找到在电弧切割缝附近的传导电流,同时射流径向传输更多的热量,从而使切口宽度和切口两边的熔料在底部法兰和凝固,形成不容易清洁,挂渣和切口在边缘上形成的热熔圆角太多。
  c. When the cutting speed is too low, because of the anode plasma arc cutting, in order to maintain the stable arc itself and the anode spot or the area near the anode, it is necessary to find the conduction current near the arc cutting seam, and at the same time, the jet radially transmits more heat, so that the width of the incision and the molten materials on both sides of the incision are solidified at the bottom flange, forming a difficult to clean, There are too many hot-melt fillets formed on the edge by slag hanging and notching.
  当速度非常低时,电弧甚至会因为宽切而熄灭。因此,良好的切削质量与切削速度是分不开的。
  When the speed is very low, the arc will even go out because of wide cutting. Therefore, good cutting quality and cutting speed are inseparable.
  5. 但是,为了确保设备不被损坏,有必要确保环境温度达到设备规范中规定的标准(15°C到35°C)。
  5. However, in order to ensure that the equipment is not damaged, it is necessary to ensure that the ambient temperature reaches the standard specified in the equipment specification (15 ° C to 35 ° C).
  注:二氧化碳激光管不加防冻液,防冻液会影响光的质量,影响散热,散热不好,功率和使用寿命可能会受到影响。
  Note: carbon dioxide laser tube without antifreeze, antifreeze will affect the quality of light, affect heat dissipation, poor heat dissipation, power and service life may be affected.
