技术领域Technical field

本发明涉及铣削加工领域，尤其涉及高速铣削微量润滑供液喷嘴结构、分离与回收机构及***。The invention relates to the field of milling processing, in particular to a structure, a separation and recovery mechanism and a system for a high-speed milling micro-lubricating liquid supply nozzle.

背景技术Background technique

铣削是指使用旋转的多刃刀具切削工件，是高效率的加工方法。铣削加工时，铣刀的旋转是主运动，铣刀或工件沿坐标方向的直线运动或回转运动是进给运动，适用于平面类和沟槽类工件的加工。Milling refers to the use of a rotating multi-blade tool to cut a workpiece, which is a highly efficient machining method. When milling, the rotation of the milling cutter is the main motion. The linear motion or the rotary motion of the milling cutter or the workpiece along the coordinate direction is the feed motion, which is suitable for the machining of plane and grooved workpieces.

高速铣削是以快速进给速度进行切屑量小，但金属去除率比深度铣削效率高，从而延长刀具使用寿命，减少非加工时间的一种高效铣削方法，它的应用特别适合现代生产快速反应的特点。High-speed milling is an efficient milling method that uses a small amount of chips at a fast feed rate but a high metal removal rate than deep milling, which extends tool life and reduces non-machining time. Its application is particularly suitable for modern production and rapid response. Features.

目前，切削加工过程中大量使用润滑剂，即浇注式加工，对环境和工人健康伤害很大。由于环保要求，润滑剂的废液必须经过处理、达标后才能排放，废液处理耗资巨大，高达润滑剂成本的54％，使人们不得不对润滑剂作重新评价。At present, a large amount of lubricants are used in the cutting process, that is, casting processing, which is very harmful to the environment and workers' health. Due to environmental protection requirements, the waste liquid of the lubricant must be treated and reached the standard before it can be discharged. The waste liquid treatment is costly, up to 54% of the cost of the lubricant, which makes people have to re-evaluate the lubricant.

微量润滑也叫做最小量润滑Minimal Quantity Lubrication(MQL)，是一种金属加工的润滑方式，指将压缩气体(空气、氮气、二氧化碳等)与极微量的润滑油混合雾化后，形成微米级的液滴，喷射到加工区进行有效润滑的一种切削加工方法。这一技术在保证有效润滑和冷却效果的前提下，使用最小限度的磨削液(约为传统浇注式润滑方式用量的千分之一)，以降低成本和对环境的污染和对人体的伤害。Micro-lubrication, also known as Minimal Quantity Lubrication (MQL), is a metal processing lubrication method that combines compressed gas (air, nitrogen, carbon dioxide, etc.) with a very small amount of lubricating oil to form a micron-scale. A method of cutting a droplet that is injected into a processing zone for effective lubrication. This technology uses a minimum of grinding fluid (approximately one-thousandth of the amount of traditional cast lubrication) to ensure cost and environmental pollution and damage to the human body while ensuring effective lubrication and cooling. .

微量润滑切削液通过高压气体的携带，切削液被喷射到加工区域，由于以压缩空气为动力的喷射雾滴喷射出以后便不再受到约束，其运动将会发生扩散、漂移等，不再可控。因此，颗粒微小的雾滴扩散到工作中，不仅对环境造成极大的污染而且会对工作人员造成极大的健康危害。当雾滴的直径小于4μm甚至能引起操作人员的各种各样的职业病，如呼吸***疾病、皮肤癌等。根据实际报道即使短时间暴露在这种环境下也有可能损坏肺功能。为此美国职业安全健康研究所建议矿物油雾滴的暴露极限浓度为0.5mg/m³。为了确保工作人员的健康，必须对微量润滑过程微小液滴加以控制。The micro-lubricating cutting fluid is carried by the high-pressure gas, and the cutting fluid is sprayed into the processing area. Since the jet of the compressed air-driven jet is ejected, it is no longer constrained, and its movement will spread, drift, etc. control. Therefore, the tiny droplets of particles diffuse into the work, which not only causes great pollution to the environment, but also causes great health hazards to the workers. When the diameter of the droplets is less than 4 μm, it can even cause various occupational diseases of the operator, such as respiratory diseases, skin cancer, and the like. According to actual reports, even if exposed to such an environment for a short period of time, it is possible to damage lung function. To this end, the US Occupational Safety and Health Research Institute recommends that the limit concentration of mineral oil droplets be 0.5 mg/m ³ . In order to ensure the health of the staff, it is necessary to control the tiny droplets in the micro-lubrication process.

高速铣削产生大量的切屑，并随着工件的旋转运动四散，不利于收集，严重影响环境卫生。High-speed milling produces a large amount of chips, which are scattered with the rotation of the workpiece, which is not conducive to collection and seriously affects environmental sanitation.
