火焰切割机应注意的问题
Notices for Flame Cutting Machine
数控火焰切割机在切割过程中的应用,通常有不同的切割缺陷的一种或另一种。为了提高切削质量,简要介绍了在不同切削条件下控制质量的要点:
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. 锻件切削中应注意的几个问题
1. Points for Attention in Forging Cutting
因为锻件表面的氧化膜厚度,另外,氧化膜的燃烧点高于熔点,因此,切削过程中很容易出现切割中断的现象,导致切割质量下降和效率降低。为此,当锻件被切割时,,首先去除切割区上下表面的氧化垢,然后切割氧化膜,提高切削速度和质量。
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. 轧制坯冷床齿板切削中防止变形的要点
2. Key Points of Deformation Prevention in Cutting Tooth Plate of Rolling Billet Cold Bed
在切削过程中,控制工件的变形是非常重要的,如果按常规安排切削路线,就会造成工件的变形和超差,即使是整容手术也很难满足尺寸要求,最终,该产品将被报废。因此,合理安排采气路径是非常重要的。
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.
