火焰切割机注意事项
Notices for Flame Cutting Machine
在使用数控火焰切割机切割的过程中,经常会有这样或那样的不同的切割缺陷产生。为提高切割质量,在不同切割情况下控制质量的要点简单介绍下:
In the process of cutting with numerical control flame cutting machine, there are often different kinds of cutting defects. In order to improve the cutting quality, the key points of controlling the quality under different cutting conditions are briefly introduced.
1. 锻件切割中应注意的要点
1. Points for Attention in Forging Cutting
由于锻件表层氧化皮较厚,再加上氧化皮燃点高于熔点,所以在切割中容易出现切割中断现象,造成切割质量下降和工效降低。为此在锻件切割时,应首先去除切割区域中上下表面的氧化皮后再切割,以提高切割速度和切割质量。
Because the oxide skin on the surface of forgings is thicker and the burning point of oxide skin is higher than the melting point, cutting interruption is easy to occur in the cutting process, resulting in the decline of cutting quality and efficiency. Therefore, in order to improve the cutting speed and quality, the oxide skin on the upper and lower surfaces of the cutting area should be removed before cutting forgings.
2. 轧制方坯冷床齿板切割中防变形的要点
2. Key Points of Deformation Prevention in Cutting Tooth Plate of Rolling Billet Cold Bed
在切割中如何控制工件变形是非常重要的,如按常规安排切割路线会造成工件变形和超差,即使整形也很难达到尺寸要求,最终将会使产品报废。因此合理地安排气割路线是非常关键的。
How to control the workpiece deformation is very important in cutting. For example, according to the routine cutting route, the workpiece deformation and overshoot will be caused, even if the shaping is difficult to meet the size requirements, and eventually the product will be scrapped. Therefore, it is very important to arrange gas cutting routes reasonably.
