如何延长数控切割机使用的寿命

2020-01-17 11:07:12 文章来源:www.jnzrtcsk.com 217

根据使用说明书的要求,采取合理的切线距离,切断与切割喷嘴和工件表面的距离,当穿孔时,尽量使用2倍的正常切割距离,或采用等离子弧可以达到很高高度.数控切割等离子的正确压力和流量对耗材的使用寿命很重要.如果压力过高,电极的寿命将大大降低.压力太低,喷嘴的寿命会受到影响.推荐阅读: 使用数控火焰切割机时应注意些什么
According to the requirements of the instructions, reasonable tangent distance should be adopted to cut off the distance from the cutting nozzle and the workpiece surface. When perforating, the normal cutting distance should be twice as long as possible, or plasma arc can be used to reach a high height. The correct pressure and flow rate of plasma in NC cutting are very important for the service life of consumables. If the pressure is too high. If the pressure is too low, the life of the nozzle will be affected. Recommended reading: What should we pay attention to when using the numerical control flame cutting machine
切割机不能在超过工作厚度的钢板上打孔,正常的穿孔厚度是正常切削厚度的1/2.为了使喷嘴超载(即超过喷嘴的工作电流),喷嘴很快就会损坏.电流强度适用于喷嘴工作电流的95%.例如,对100A喷嘴的电流强度应设置150A的电路.
Cutting machine can't punch holes on the steel plate which exceeds the working thickness. The normal punching thickness is 1/2 of the normal cutting thickness. In order to make the nozzle overload (i.e. exceed the working current of the nozzle), the nozzle will soon be damaged. The current intensity is suitable for 95% of the working current of the nozzle. For example, 150A circuit should be set for the current intensity of 100A nozzle.
等离子系统需要干燥和洁净的等离子体可以正常工作,数控切割脏污通常气体压缩系统的问题,它会缩短易损件的使用寿命,非正常损坏.测试气体质量的测试方法是割炬处于状态,镜子放在它的下部,消耗割炬内的气体,如果出现在镜子上的水分和雾,你就需要找出原因和正确.
The plasma system needs dry and clean plasma to work properly. CNC cutting dirty contamination is usually a problem of gas compression system. It will shorten the service life of vulnerable parts and cause abnormal damage. The test method of gas quality is that the cutting torch is in state, the mirror is placed at the bottom of the torch, and the gas in the cutting torch is consumed if it appears in the mirror. Water and fog on it, you need to find out the reason and the right one.
尽可能从边缘处不刺.以边缘为出发点,延长消费品的使用寿命.正确的方法是将喷嘴直接对准工件的边缘,然后启动等离子弧.在电弧开始时,喷嘴和电极消耗非常快.开始前,割炬应放置在切削金属的距离处.
Starting from the edge, extend the service life of consumer goods. The correct way is to direct the nozzle to the edge of the workpiece, and then start the plasma arc. At the beginning of the arc, the nozzle and the electrode consume very fast. Before the beginning, the torch should be placed at the distance of the cutting metal.
防喷化学涂层有助于减少保护壳上的积渣.但是,在割炬喷上数字控制之前,必须将保护壳去掉.如果等离子弧仅延伸到工件表面,等离子弧将在切割的开始和结束时产生拉伸和延伸,这将对喷嘴造成不正常的损害.采用正确的边启动技术,选择合适的"弧"信号时间,可以避免这一问题的发生.
Blowout-proof chemical coating helps to reduce slag deposit on the protective shell. However, the protective shell must be removed before the torch is sprayed with digital control. If the plasma arc only extends to the surface of the workpiece, the plasma arc will stretch and extend at the beginning and end of the cutting, which will cause abnormal damage to the nozzle. The correct side-start technique is adopted. The problem can be avoided by choosing the appropriate arc signal time.http://www.jnzrtcsk.com
