절단 정확도에 영향을 미치는 많은 요소가 있습니다. 레이저 파이프 절단기. 구체적으로 다음과 같은 주요 이유가 있습니다.
1.레이저빔의 모양
레이저의 빔은 테이퍼형이므로 잘라낸 슬릿도 테이퍼형입니다. 이 경우 0.6MM 스테인레스 스틸의 절단 두께는 3MM 슬릿보다 작습니다. 따라서 레이저 광속도의 형태는 금속 파이프 레이저 파이프 절단기의 절단 정확도에 영향을 미치는 주요 요소가 됩니다. 이러한 원뿔 모양의 레이저 광속 조건에서는 가공물의 두께가 두꺼울수록 정확도가 낮아집니다.
2. 레이저 빔의 스폿 크기
스폿 크기도 파이프 레이저 절단기의 절단 정확도에 영향을 미치는 요소 중 하나입니다. 원뿔 모양의 레이저가 함께 초점을 맞추면 스폿이 점점 작아지고 레이저 절단 정확도가 높아집니다. 가장 작은 지점은 최대 0.01mm까지 가능하며 작은 절단 간격을 잘라내어 가공 정확도를 보장할 수 있습니다.
3. 파이프의 다양한 재질
Different materials pipe laser cutting machine cutting accuracy is also less different, even the same material, if the composition of the material is different, the cutting accuracy will also be different. Therefore, the workpiece material on the pipe laser cutting accuracy also has a certain impact. For example, under the same circumstances, stainless steel has higher cutting accuracy and smoother cutting surface than aluminum.
Generally speaking, different pipes to be cut have different physical and chemical properties.
In terms of physical properties, the pipes to be cut vary in terms of hardness, melting and boiling points, and whether they are easy to melt. In terms of chemical properties, such as the flammability, stability, oxidation, and combustion-supporting properties of the pipes to be cut, there are also great differences. This makes the different pipes to be cut different in terms of the size of the chuck, the type and pressure of the auxiliary gas. And the requirements such as laser cutting power are different.
Under normal circumstances, the greater the thickness of the pipe to be cut, the higher the laser cutting power required. When cutting pipes of special materials such as aluminum pipes, copper pipes, stainless steel pipes, and even pipes made of materials with excellent oxidation resistance, as well as pipes of special shapes such as special-shaped pipes, H-shaped steel, channel steel, and angle steel, the laser The cutting power, the choice of auxiliary gas type, and the performance of the chuck itself also have different requirements. When cutting and processing lengthened and weighted pipe fittings, in addition to considering laser power and auxiliary gas, the selection of supporting components must also be considered to ensure the accuracy of the entire cutting process.
4. 공작물 두께
가공물의 두께가 두꺼울수록 정확도는 낮아지고 슬릿은 커집니다. 레이저 빔이 원뿔형이므로 절단 슬릿도 원뿔형입니다. 예를 들어 두께가 0.3mm인 소재의 절단 간격은 두께가 2mm인 소재보다 훨씬 작습니다.
5. 절단 시스템 선택
For hardware to fully play its role, suitable software assistance is needed, such as an excellent pipe cutting system. The more popular pipe cutting systems on the market now include cutting systems independently developed by FS, Siemens, Beckhoff or companies. Different systems support different cutting methods, pipe shapes, and number of chucks. For example, FSCUT’s system supports offset tube center error in production to improve through holes cutting precision. Excellent tube cutting software is one of the necessary factors to achieve high precision.
6.보조가스의 선정
When the laser cutting machine is working, the light spot formed by focusing the laser beam through the lens is irradiated on the surface of the material to be cut, causing the temperature to rise in a very short time, thereby reaching the melting point or boiling point of the material to be cut. During the cutting process, the surface of the material to be cut can reflect the laser to a certain extent. During cutting, auxiliary gas can be blown to increase the absorption of the laser by the surface of the material to be cut and improve cutting efficiency. Auxiliary gases generally use oxygen, nitrogen, compressed air and other inert gases.
Oxygen is commonly used as an auxiliary gas because oxygen promotes the oxidation reaction on the surface of the pipe being cut, thereby improving cutting efficiency. When the laser cutting power and cutting speed are constant, the greater the oxygen pressure, the larger the cutting seam, and the cutting section stripes will be thicker and larger; when the oxygen pressure is reduced, the cutting seam becomes thinner, and the cutting section stripes are thin and smooth, but when When the pressure drops to a certain value, the cutting effect on one side of the pipe will be significant, but at the same time, slag will appear. The slag falling to the opposite side will affect the entire cutting accuracy, and sometimes it will even be difficult to cut off the cut pipe.
When cutting high-thickness pipes, special-shaped pipes or pipes of special materials, nitrogen and other inert gases need to be used as auxiliary gases. Combined with the metal and physical properties of the pipe being cut, compressed air can be selected as the auxiliary gas in order to control costs without affecting the overall cutting efficiency.
