Background
The general material of circular saw blade mainly possesses the cutting off of low hardness carbon steel and non ferrous metal stick and tubular product, and the pipe cutting circular saw blade of superhard materials is used for the milling process of difficult cutting material (heat-resisting iron, the high rigidity steel of stainless steel), and the saw bit number of teeth is decided by saw bit diameter, work piece thickness and material, generally speaking, the saw bit number of teeth that is used for cutting thinner work piece is more, the tooth chamber is less, and interior thick outer thin boss type circular saw blade is one kind among the circular saw blade, but its high temperature resistance of current interior thick outer thin boss type circular saw blade and wearability are poor to its life has been reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an interior thick outer thin boss type saw blade to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an interior thick outer thin boss type saw blade, includes saw disc, chip groove, glass fiber coating and nanometer chromium oxide coating, the chip groove has all been seted up to both sides around the saw disc surface, and the surface of saw disc is scribbled and is equipped with the glass fiber coating, and simultaneously, one side that the saw disc was kept away from to the glass fiber coating is scribbled and is equipped with nanometer chromium oxide coating.
Preferably, the middle part of the saw disc is of a convex structure, and a plurality of saw teeth are uniformly distributed on the outer surface of the saw disc.
Preferably, the middle end of the inner surface of the saw disc is provided with a mounting hole, and the inner cavity of the saw disc, which is positioned at the outer side of the mounting hole, is provided with four limiting holes at equal angles.
Preferably, the thickness of the glass fiber coating is forty to eighty microns, and the thickness of the nano chromium oxide coating is sixty to one hundred microns.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model discloses scribble at the surface of saw disc and established the glass fiber coating, can improve the high temperature resistance of saw disc, make it can not lead to self intensity step-down because of the high temperature in the cutting process that lasts, one side of keeping away from the saw disc at the glass fiber coating is scribbled and is established nanometer chromium oxide coating, can improve the wearability of saw disc, improve its cutting time, it is poor to have solved its high temperature resistant and the wearability of current thick outer thin boss type circular saw piece, thereby its life's problem has been reduced.
2. The utility model discloses the chip groove has all been seted up to both sides around the saw disc surface, can improve the saw disc at cutting in-process chip removal ability to its cutting rate has been accelerated.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the structure of the glass fiber coating of the present invention.
In the figure: 1 saw disc, 2 saw teeth, 3 mounting holes, 4 limiting holes, 5 chip grooves, 6 glass fiber coatings and 7 nanometer chromium oxide coatings.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The saw disc 1, the saw teeth 2, the mounting holes 3, the limiting holes 4, the chip grooves 5, the glass fiber coating 6 and the nano chromium oxide coating 7 are all universal standard parts or parts known by a person skilled in the art, and the structure and the principle of the parts are known by the person skilled in the art through technical manuals or conventional experimental methods.
Referring to fig. 1-2, an inner thick and outer thin boss type circular saw blade comprises a saw disc 1, a chip removing groove 5, a glass fiber coating 6 and a nano chromium oxide coating 7, wherein the middle part of the saw disc 1 is of a convex structure, a plurality of saw teeth 2 are uniformly distributed on the outer surface of the saw disc 1, a mounting hole 3 is formed in the middle end of the inner surface of the saw disc 1, four limiting holes 4 are formed in the inner cavity of the saw disc 1 and positioned on the outer side of the mounting hole 3 at equal angles, the chip removing grooves 5 are formed in the front side and the rear side of the outer surface of the saw disc 1, so that the chip removing capability of the saw disc 1 in the cutting process can be improved, the cutting speed is accelerated, the glass fiber coating 6 is coated on the outer surface of the saw disc 1, the high temperature resistance of the saw disc 1 can be improved, the self strength of the saw disc cannot be reduced due to overhigh temperature in the continuous cutting process, and the nano chromium oxide coating 7 is coated on one, the wear resistance of the saw disc 1 can be improved, the cutting time of the saw disc is prolonged, the thickness of the glass fiber coating 6 is forty-eighty microns, and the thickness of the nano chromium oxide coating 7 is sixty-one hundred microns.
When the novel saw disc is used, the glass fiber coating 6 is coated on the outer surface of the saw disc 1, the high temperature resistance of the saw disc 1 can be improved, the strength of the saw disc 1 cannot be reduced due to overhigh temperature in the continuous cutting process, the nano chromium oxide coating 7 is coated on one side, far away from the saw disc 1, of the glass fiber coating 6, the wear resistance of the saw disc 1 can be improved, the cutting time of the saw disc is prolonged, the problems that the conventional circular saw disc with the thick inner part and the thin outer part and the boss is poor in high temperature resistance and wear resistance and the service life of the circular saw disc is prolonged are solved, chip removal grooves 5 are formed in the front side and the rear side of the outer surface of the saw disc 1, the chip removal capacity of the saw disc 1 in the cutting process can be improved, and the cutting speed.
