Abstract
The utility model relates to a black diamond saw blade which can greatly prolong the whole cutting service life of the saw blade. The saw blade comprises a saw blade; every three of sawteeth at the periphery of the saw blade form a group; and each group of sawteeth comprises two hard alloy teeth and a diamond coating alloy tooth. The utility model has the advantages that the diamond coating alloyis taken as the main cutting part of the saw bit, thereby reducing the abrasion of hard alloy, and greatly prolonging the cutting service life of the saw blade; and cutting experiment proves that in the state that the black diamond saw blade and the hard alloy saw blade are cut in the same manner, the service life of the black diamond saw blade is more than doubled than that of the hard alloy sawblade.
Description
Technical field
The utility model relates to a kind of NCC saw blade that can improve the saw blade integral cutting life-span greatly, belongs to saw blade and makes the field.
Background technology
The hard alloy saw blade of Xiao Shouing in the market, on structural design, the sawtooth of saw blade closes carbide button by hard and constitutes.Its weak point: the one, not wear-resisting, easy to wear, cutting efficiency is low; Two are to use the life-span short, have increased user's use cost.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, it is low to design a kind of wearing and tearing, the NCC saw blade of long service life.
Design: in order to realize above-mentioned purpose of design.The matrix material of NCC saw blade is mainly instrument carbon steel, and the material of alloy has carbide alloy and diamond coatings alloy respectively; Diamond coatings is a kind of a kind of hard composite coating that is formed by the nanocrystalline and amorphous strengthening mechanism by metallic nano crystal and amorphous diamond-like coating, have low-friction coefficient, high rigidity, high elastic modulus, high-wearing feature, high heat conductance and good chemical stability and resistance to corrosion, surface microhardness can reach 15～30GPa, and the wear rate under the normal temperature condition can reach 3 * 10-17m3/Nm; Carbide alloy is a major ingredient with tungsten carbide or titanium carbide mainly, is binding agent with the cobalt, and hardness number only reaches 89～93HRA, far away from the character of diamond coatings alloy.Therefore, the utility model is on structural design, and it is one group that the NCC saw blade designs per three teeth, and every group is respectively two carbide alloy and a diamond coatings alloy composition, takes every group of regularity distribution.The low temperature high-frequency induction welding technique, the carbide alloy in every group is designed to left and right tooth, and anterior angle is ground and had preceding cutting edge inclination; The diamond coatings alloy designs is flat tooth, and anterior angle is not ground and is zero degree; Diamond coatings alloy relief grind size is lower than about carbide alloy relief grind size 0.25mm.The diamond coatings alloy is cut towel and is cut towel 0.05mm greater than carbide alloy, mainly reduces the cutting quantity of carbide alloy.Its technical scheme: the NCC saw blade, it comprises saw blade, and per three teeth of the sawtooth of saw blade periphery are one group, and every group is respectively two hard-metal inserts and a diamond coatings carbide button composition.
The utility model is compared with background technology, with the main cutting character of diamond coatings alloy as saw blade, the wearing and tearing of carbide alloy have not only been reduced, improve the cutting life-span of saw blade integral body greatly, prove through cutting experiment, NCC saw blade and hard alloy saw blade are under the cutting condition of equal mode, and be higher than more than the twice service life of the service life of NCC saw blade than hard alloy saw blade.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～8.A kind of NCC saw blade, it comprises saw blade, and per three teeth of the sawtooth of saw blade periphery are one group, and every group is respectively two hard-metal inserts and a diamond coatings carbide button composition.Carbide alloy is that left and right tooth and anterior angle are ground and had preceding cutting edge inclination, and the diamond coatings alloy is that flat tooth and anterior angle are not ground and be zero degree.Diamond coatings alloy relief grind size is lower than in carbide alloy relief grind size 0.20～0.30mm scope optional and comprise end value.Be equipped with diamond coatings on the carbide alloy sawtooth.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just to simple description of the present utility model; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (4)
