Abstract
The utility model discloses a cemented carbide glass cutter, which belongs to the technical field of cutting tools. A cutter body of the cemented carbide glass cutter is a cemented carbide base body, and a diamond-like coating is arranged on the surface of the cemented carbide base body. The diamond-like coating can increase stiffness and abrasive resistance of cutting edges, and can obviously prolong service life of the glass cutter when the glass cutter is used for cutting hard glass, and a diamond-like film surface coating is easy to be produced in large scale. The cemented carbide glass cutter is easy to produce, has strong practicality and spreading value, and is suitable for large-scale popularization and application.
Description
Technical field
The utility model belongs to the technical field of cutting tool, is specifically related to a kind of Wimet glass cutter that is used for glass-cutting.
Background technology
The present glass cutting cutter that uses on the market, used material comprises Wimet, polycrystalline diamond or Wimet and adamantine sandwich.For Wimet, conventional Wimet selects for use the higher trades mark such as YG5 of hardness to make usually, and the cutters that these Wimet are made still can not make us in wear resistance and work-ing life very satisfied when glass-cutting.Though polycrystalline diamond hardness height, wear resistance is good, processing difficulties, and the cost height has also limited it and has applied.Though the hardness of diamond-coated tools is very high; but the temperature of depositing diamond film is generally at 700 ~ 900 ℃, and the Co in the Wimet has a significant impact film, and big in carbide surface depositing diamond film technical difficulty; be difficult to form large-scale production, the cost height.
Quasi-diamond (Diamond Like Carbon, DLC) the metastable state decolorizing carbon formed by sp2 hydridization and sp3 hydridization carbon of film, have higher hardness, high optics (particularly infrared and microwave frequency band) transmitance, favorable mechanical and frictional behaviour, therefore have application promise in clinical practice in a lot of fields such as machinery, electronics, optics, acoustics, computer.Militarily, can be used as the infrared anti-reflection film and the protective membrane of optical system in the thermal imaging system on tank, panzer, the warship; On civilian, can be used as the high strength protective membrane of CD, disk; The depositing temperature of diamond like carbon film is then lower, and normal temperature just can deposit down, and the influence of Co is not very big just like this, and equally also can improve the hardness of cutter.
The utility model content
The purpose of this utility model is to provide a kind of being easy to produce hardness height, the Wimet glass cutter that wear resistance is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the Wimet glass cutter, its cutter hub is a hard alloy substrate, is provided with diamond-like coating on the surface of hard alloy substrate.
Described diamond-like coating is located at the blade position.
The thickness of described diamond-like coating is the 1-10 micron.
Owing to adopted above-mentioned structure, diamond-like coating of the present utility model can improve the hardness and the wear resistance of cutting cutting edge, when cutting harder glass, obviously improve the glass cutter life-span, and diamond like carbon film top coat ratio be easier to accomplish scale production.The utility model is easy to produce, and has very strong practicality and promotional value, is fit to large-scale promotion application.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the sectional view of Wimet glass cutter.
Embodiment
As shown in Figure 1, Wimet glass cutter described in the utility model, cutter hub are hard alloy substrates 1, are provided with diamond-like coating 2 on the surface of hard alloy substrate 1.Diamond-like coating 2 preferably is arranged on the blade position that is located at the cutter hub both sides.The thickness of described diamond-like coating 2 is the 1-10 micron.Diamond-like coating 2 can adopt the electric arc evaporation coating method at cemented carbide substrate surfaces depositing diamond-like film coating, and the thickness of control diamond like carbon film top coat is chosen as 1 micron, or 5 microns, or 10 microns.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
Claims (3)
