Knife handle suitable for low-temperature minimal quantity lubrication

Abstract

The invention provides a knife handle suitable for low-temperature minimal quantity lubrication, and belongs to the technical field of cooling and lubrication of numerical control machine tools. The knife handle comprises a knife handle body, a peripheral static structure, a multi-layer sealing structure, a heat insulation structure and a bearing supporting structure. The problems that in the minimal quantity lubrication technology, the cooling performance is insufficient, and lubrication is insufficient in the low-temperature cooling machining technology are solved, the oxygen isolation protection effect of an ultralow-temperature medium, the cooling effect of the ultralow-temperature medium and the anti-attrition lubrication effect of minimal quantity lubrication are integrated, and therefore a good machining effect is achieved on the aspect of materials difficult to machine. The knife handle can be used for machining the materials difficult to machine through a traditional numericalcontrol machine tool, the application range of an outer rotating inner knife handle is widened, the cutting heat of the materials difficult to machine in the cutting machining process is effectivelyreduced, the service life of a knife is prolonged, traditional cutting fluid is replaced, and green manufacturing is achieved.

Description

technical field [0001] The invention belongs to the technical field of cooling and lubrication of numerical control machine tools, and in particular relates to a tool handle suitable for low-temperature micro-lubrication. Background technique [0002] At present, some difficult-to-machine materials such as titanium alloys and high-temperature alloys with excellent properties such as high temperature resistance and corrosion resistance have become the main materials used in the manufacture of components in aerospace and other high-end equipment fields. However, these difficult-to-machine materials usually exhibit high viscosity, high toughness, anisotropy and other characteristics, which bring a series of difficulties to the cutting process: the temperature in the cutting area is high, the tool life is short, and the surface quality of the parts is generally difficult to meet the target requirements. The latest research at home and abroad shows that, under the condition of gi...
