Abstract
The utility model relates to a concave cutter head of cutting saw. The technical scheme is: a concave is prefabricated on the cutting surface between blades of the cutting head. The blades and concave are collated with hard thin film, which includes one of diamond, cubic boron nitride, iron nitride, and aluminium sesquioxide, with the thickness being 0.0001mm to 0.1mm. The utility model has the effect that: since hard materials such as diamond, cubic boron nitride, iron nitride, and aluminium sesquioxide have the high rigidity, and after the combination with the concave cutter head undergoing coating technique and hard alloy, the utility model can greatly enhance the anti-wearing performance of concave cutter head, thus enhancing the service life of saws.
Description
Technical field
The utility model relates to the concave surface cutter head that uses on a kind of cast-cutting saw slice.
Background technology
Present cast-cutting saw slice matrix uses the steel material usually, and cutter head uses Hardmetal materials, and the two uses as cast-cutting saw slice by the welding back.Easier discharge bits sheet when the saw blade that the saw blade that the concave surface cutter head is made is made with respect to the plane cutter head cuts, cutting efficiency is higher, has the too late effect of flat knife.But, cause service life limited because the hardness and the anti-wear performance of carbide alloy are relatively low; And it is very big to use superhard material such as diamond directly to be processed into the cutter head difficulty that has concave surface, and cost is also very high.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and the concave surface cutter head that uses on the cast-cutting saw slice of a kind of convenient processing, long service life is provided.
Its technical scheme is: the cut surface between the blade of cutter head matrix is shaped on concave surface in advance, is coated with at blade and concave surface and is coated with the ganoine thin film coating.Described ganoine thin film coating comprises a kind of in diamond, cubic boron nitride, nitrided iron, the alundum (Al, and its thickness is between the 0.0001-0.1 millimeter.
Effect of the present utility model is: because hard materials such as diamond, cubic boron nitride, nitrided iron, alundum (Al have very high hardness property, after passing through coating process and the concave surface cutter head of carbide alloy combining, improved the anti-wear performance of concave surface cutter head greatly, thus the service life of having improved saw blade.
Description of drawings
Accompanying drawing 1 is the front view of a kind of specific embodiment of the utility model; Accompanying drawing 2 is left views of Fig. 1; Accompanying drawing 3 is vertical views of Fig. 1.1 is concave surface cutter head matrix among the figure, the 2nd, and blade, the 3rd, concave surface.
The specific embodiment:
With reference to accompanying drawing, concave surface cutter head matrix 1 adopts Hardmetal materials, article two, blade 2 is symmetrically distributed in two edges of matrix side, matrix between two blades 2 is processed with arc-shaped concave 3, is being coated with diamond after being coated with 0.09 millimeter of thickness or cubic boron nitride, nitrided iron, aluminum oxide coating on blade 2, the concave surface 3.
The thickness of the foregoing description floating coat is according to the environment for use difference, and its thickness is selected between the 0.0001-0.1 millimeter, and coating material is selected between hard rock or cubic boron nitride, nitrided iron, alundum (Al, does not enumerate one by one here.
Claims (2)
1, the concave surface cutter head that uses on a kind of cast-cutting saw slice, the cut surface between the blade of cutter head matrix is shaped on concave surface in advance, it is characterized in that: be coated with at blade and concave surface and be coated with the ganoine thin film coating.
2, the concave surface cutter head that uses on the cast-cutting saw slice according to claim 1, described ganoine thin film coating comprise a kind of in diamond, cubic boron nitride, nitrided iron, the alundum (Al, and its thickness is between the 0.0001-0.1 millimeter.
