数控开料机设备润滑的注意事项众所周知,数控开料机不止质量要过硬,后期的使用中以及使用后的保养也尤为重要。很多操作手对保养并不熟悉,日常的一些习惯也往往存在误区,长时间下来,往往对设备造成了损伤,维护保养,除了对机械、电气设备的检查、调整、紧固以外,重要的工作就是润滑。下面介绍一下数控开料机,封边机等机械设备润滑保养中的的常见误区。 1、盲目添加要出事 润滑并不是这么简单,它是综合运用流体力学、固体力学、材料学、应用数学、物理化学等基础理论,来研究润滑原理、润滑材料和润滑方式,控制有害摩擦、磨损的一门科学,加油仅仅是润滑之中的一环而已。 一台设备的润滑,其实从它的设计阶段就开始了,并且贯穿于整个设备使用寿命始终。 2、过量添加 弊大于利 事实并非如此,简单地说,人们把润滑油加到两个摩擦表面之间,目的是在两个摩擦表面形成薄薄的油膜,避免直接接触,从而减少磨损。 但是,考虑到加润滑油的某些副作用,就必须严格控制加油量,例如在减速器中,为了减少齿轮运动中阻力和油的温升,浸入油的齿轮深度以1~2个齿高为宜,转速高的加油量还应少些。 3、随意加油使不得 设备润滑油的选择,根据机器的工作条件、工作环境、摩擦表面具体特点和润滑方式的不同,选用的润滑油的种类、牌号也不相同。 转速高、形成油楔作用能力强的设备,应选用粘度低的润滑油;设备摩擦表面单位面积的负荷大时,应选用粘度大、油性较好的润滑油; 设备工作环境温度较高时,应采用粘度较大、闪点较高、油性较好、稳定性较强的润滑油或滴点较高的润滑脂; 设备摩擦表面之间的间隙越小,选择润滑油粘度应越低;摩擦表面越粗糙,选择润滑油粘度应越大,若选择润滑脂工作锥度应越小;压力循环润滑中,油温较高,应使用粘度较大的润滑油。 不同型号的数控开料机的润滑油是严格根据上述原则和实验结果选择的。一般情况下不能替换使用,如果任意替换使用就会破坏设备润滑环境,使机器设备受到磨损,造成经济损失。 As we all know, not only should the quality of CNC cutting machines be excellent, but the maintenance in later use and after use is also particularly important.Many operators are not familiar with maintenance, and some daily habits often have misunderstandings. Over a long period of time, it often causes damage to the equipment. Maintenance, in addition to the inspection, adjustment, and fastening of mechanical and electrical equipment, the important job is lubrication.The following describes the common misunderstandings in the lubrication and maintenance of mechanical equipment such as CNC cutting machines and edge banding machines. 1. Blindly adding will cause an accident Lubrication is not that simple. It is a science that comprehensively uses basic theories such as fluid mechanics, solid mechanics, materials science, applied mathematics, and physical chemistry to study lubrication principles, lubricating materials, and lubrication methods to control harmful friction and wear. Refueling is only one part of lubrication. The lubrication of an equipment actually begins from its design stage, and runs through the entire service life of the equipment. 2. Excessive addition does more harm than good This is not the case. Simply put, people add lubricating oil between the two friction surfaces. The purpose is to form a thin oil film on the two friction surfaces to avoid direct contact and thereby reduce wear. However, taking into account some of the side effects of adding lubricating oil, it is necessary to strictly control the amount of refueling. For example, in a reducer, in order to reduce the resistance of the gear movement and the temperature rise of the oil, the depth of the gear immersed in the oil should be 1 to 2 teeth high, and the amount of refueling at high speeds should be less. 3. Feel free to refuel The choice of equipment lubricating oil depends on the working conditions of the machine, the working environment, the specific characteristics of the friction surface and the different lubrication methods, and the types and grades of lubricating oil selected are also different. For equipment with high speed and strong ability to form oil wedges, low-viscosity lubricants should be used; when the load per unit area of the friction surface of the equipment is large, lubricants with high viscosity and good oil properties should be used.; When the operating ambient temperature of the equipment is high, lubricating oil with high viscosity, high flash point, good oiliness and strong stability or grease with high drop point should be used.; The smaller the gap between the friction surfaces of the equipment, the lower the viscosity of the lubricating oil should be selected; the rougher the friction surface, the greater the viscosity of the lubricating oil should be selected, and the smaller the working taper of the grease should be selected; in pressure circulation lubrication, the higher the oil temperature, the higher the viscosity of the lubricating oil should be used. Lubricating oil. The lubricants of different types of CNC cutting machines are selected strictly according to the above principles and experimental results.Under normal circumstances, it cannot be replaced. If it is replaced arbitrarily, it will damage the lubrication environment of the equipment, cause wear and tear on the machinery and equipment, and cause economic losses. |
