二氧化碳激光切割機及速度與切割效果!

  基本原則:
  basic principle:
  二氧化碳激光管在冬季結冰期間,如果激光管內的水不排放干凈,就會導致激光管的冷卻層結冰膨脹,使激光冷卻層開裂。激光管不能正常工作。激光管冷卻層的凍結裂紋不在包絡范圍內。為避免不必要的損失,請采取以下防凍措施:
  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. 切斷設備的所有電源
  1. Cut off all power supply of the equipment
  2. 將激光機出口處的水管拔出,將機器內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.將空氣(壓力小于0.4MP)連接到激光機進水處,徹底清潔激光機內管和激光管中的水。
  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. 將冷水機或水泵取下,放置在高溫的房間內,防止水循環設備結冰,以免損壞冷水機和水泵部件,給您帶來不必要的麻煩;或將水從水冷卻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.
  激光切割機的切割速度和切割效果:
  Cutting speed and effect of laser cutting machine:
  激光切割無毛刺,不起皺,精度高。對于許多機電制造行業來說,由于計算機程序控制的現代數控激光切割系統可以方便地切割不同形狀和尺寸的工件,因此常常是多沖裁、成型工藝的;雖然激光切割機的處理速度還是慢于死,但它沒有死消費,不需要修理模具,而且還節省時間更換模具,從而節約處理成本,降低生產成本,所以從整體考慮更劃算。
  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.
  在工業制造系統中起著重要作用的金屬加工業中,許多金屬材料,無論其硬度如何,都可以用光纖切割機進行切割而不變形。然而,對于金、銀、銅和鋁合金等高反射性材料,激光切割是困難的,甚至是不可能的,因為它們也是良好的熱導體。
  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.
  在激光切割過程中,加入適合被切割材料的輔助蒸汽。在鋼材切割過程中,氧氣作為輔助蒸汽體,與熔融金屬發生放熱化學反應,氧化材料,同時幫助吹除切割縫內的爐渣。丙綸類塑料切割采用壓縮空氣、棉花、紙張等易燃材料切割采用惰性蒸汽。進入噴嘴的輔助蒸汽也冷卻了聚焦透鏡,防止煙灰污染透鏡座內的透鏡并導致其過熱。激光切割機的切割速度的選擇是非常重要的,可以選擇的切削速度范圍根據設備指令或由測試中,由于材料的厚度,材料,熔點、導熱系數和表面張力的大小融化和其他因素后,切割速度也相應的變化。
  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:
  激光切割機a.適當提高切割速度可以提高切口質量,即切口略窄,切口表面更平整,減少變形。
  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、切割速度過快,切割線能量低于要求值。切割縫中的射流無法迅速將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,當切削速度過低,由于陽極等離子弧切割,為了維持穩定的電弧本身和陽極斑點或陽極附近區域必須找到在電弧切割縫附近的傳導電流,同時射流徑向傳輸更多的熱量,從而使切口寬度和切口兩邊的熔料在底部法蘭和凝固,形成不容易清潔,掛渣和切口在邊緣上形成的熱熔圓角太多。
  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.
  當速度非常低時,電弧甚至會因為寬切而熄滅。因此,良好的切削質量與切削速度是分不開的。
  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,為了確保設備不被損壞,有必要確保環境溫度達到設備規范中規定的標準(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凍液,防凍液會影響光的質量,影響散熱,散熱不好,功率和使用壽命可能會受到影響。
  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.
