激光切割加工的工藝要求全介紹

激光切割技術被越來越多的行業應用,隨著科技的不斷發展以及制造業大國向我國的轉移,未來機械制造行業也突出了更高的加工要求。汽車行業、船舶行業等等都對激光切割機行業提出了不同的加工要求。

Laser cutting technology is used by more and more industries. With the continuous development of science and technology and the transfer of large manufacturing countries to China, the future mechanical manufacturing industry has also highlighted higher processing requirements. The automobile industry, shipbuilding industry and so on all put forward different processing requirements for the laser cutting machine industry.

1、控制斷裂切割

1. Control fracture cutting.

對于容易受熱破壞的脆性材料,通過激光束加熱進行高速、可控的切斷,稱為控制斷裂切割。這種切割過程主要內容是:激光束加熱脆性材料小塊區域,引起該區域大的熱梯度和嚴重的機械變形,導致材料形成裂縫。只要保持均衡的加熱梯度,激光束可引導裂縫在任何需要的方向產生。

For brittle materials which are easy to be destroyed by heat, high-speed and controllable cutting by laser beam heating is called controlled fracture cutting.  The main content of this cutting process is: laser beam heating brittle material small area, causing large thermal gradient and serious mechanical deformation in this area, resulting in material cracks. As long as a balanced heating gradient is maintained, the laser beam can guide cracks in any direction required.

2、氧化熔化切割

2. Oxidation and cutting

熔化切割一般使用惰性氣體,如果代之以氧氣或其它活性氣體,材料在激光束的照射下被點燃,與氧氣發生激烈的化學反應而產生另一熱源,稱為氧化熔化切割。

Melting cutting generally uses inert gases, if replaced by oxygen or other active gases, materials are ignited under the irradiation of laser beams, and react with oxygen to produce another heat source, called oxidation melting cutting.

3、熔化切割

3. Melt cutting

當入射的激光束功率密度超過某一值后,光束照射點處材料內部開媽蒸發,形成孔洞。一旦這種小孔形成,它將作為黑體吸收所有的入射光束能量。小孔被熔化金屬壁所包圍,然后,與光束同軸的輔助氣流把孔洞周圍的熔融材料帶走。隨著工件移動,小孔按切割方向同步橫移形成一條切縫。激光束繼續沿著這條縫的前沿照射,熔化材料持續或脈動地從縫內被吹走。

When the incident laser beam power density exceeds a certain value, the material evaporates at the irradiation point, forming a hole. Once the pore is formed, it will absorb all incident beam energy as a blackbody. The hole is surrounded by a wall of molten metal, and then the molten material around the hole is carried away by an auxiliary flow coaxial with the beam. As the workpiece moves, the hole moves along the direction of cutting to form a slit.  The laser beam continues to illuminate along the front edge of the seam, and the molten material is blown continuously or pulsating from the seam.

4、汽化切割

4. Vaporization cutting

在高功率密度激光束的加熱下,材料表面溫度升至沸點溫度的速度是如此之快,足以避免熱傳導造成的熔化,于是部分材料汽化成蒸汽消失,部分材料作為噴出物從切縫底部被輔助氣體流吹走。

When heated by a high power density laser beam, the surface temperature of the material rises to the boiling point so fast that it can avoid melting due to heat conduction, that part of the material vaporizes into vapor and disappears, and part of the material is blown away from the bottom of the notch by auxiliary gas as a jet.

以上就是激光切割加工工藝要求,未來激光切割技術會有更加好的發展,希望以上的介紹能夠真正幫到大家。

Above is the laser cutting processing technology requirements, the future laser cutting technology will have a better development, I hope the above introduction can really help everyone.
