Abstract
The utility model relates to a diamond sintered saw blade of mother-child teeth, which makes the mother tooth and child tooth have functionally benign complementarity on mechanical structure and nesting drainage etc. The diamond sintered saw blade of mother-child teeth has mother-child sawtooth with two or more than two child teeth, which can be conducted one-time powder metallurgy on alloy steel substrate, having ultra-long metallurgical combination structure of circular arc bottom of mother tooth.
Description
Technical field
The utility model relates to a kind of diamond saw blade, refers in particular to a kind of integral sintered saw blade of primary and secondary tooth disjunctor diamond that has two or more sub-teeth.As shown in Figures 1 and 2: outer diameter D is the saw blade between Φ 50mm～Φ 450mm usually.This saw blade is mainly used in the sawing processing of buildings such as stone material, jewel, pottery, reinforced concrete structure, asphalt roads engineering and refractory material, ornament materials.
Background technology
Traditional diamond saw blade all is a sawtooth one a discharge rhone welding saw blade at interval, one sawtooth, one discharge rhone integral sintered saw blade at interval, though or have a plurality of discharge rhones but not to be broken into a chain of tooth sintered saw bits of female tooth and sub-tooth, and the integral sintered saw blade of ring-band shape that does not have the discharge rhone.They are because structural shortcoming perhaps causes cutting sharp inadequately because of no discharge rhone; Though discharge rhone, also enough sharp is perhaps arranged, too poor because of structural strength, easily fall tooth, hurt sb.'s feelings, there is serious security hidden danger; Even if also there is such problem in the welding saw blade of master and slave type; And for a chain of rack saw sheet, special because in the manufacturing of large diameter integral sintered saw blade more than the Φ 150mm, exist the problem of the huge metallurgical pressure distribution inequality that can't overcome, and integral sintered a chain of rack saw sheet can't be made, also have defectives such as discharge impeded drainage simultaneously.Traditional silver-bearing copper soldering saw blade, welding efficiency is too low, and weld strength and precision are also poor.Though laser weld diamond saw blade has been strengthened weld strength to a certain extent, can expensive equipment requirement causes processing cost too high, product lacks the market competitiveness.
The utility model content
The purpose of this utility model provides that a kind of processing cost is low, production efficiency is high, precision is good, the diamond saw blade that the cutting sharpness is high and safety is firm.
The purpose of this utility model is achieved in that two or more sub-teeth that evenly distribute between female tooth of this saw blade; Female tooth has the discharge rhone, and sub-tooth also has the discharge rhone; To be that disjunctor is metallurgy sintered with the mode of connection of steel alloy matrix combine for female tooth, sub-tooth; Female tooth has the circular-arc bottom face metallurgical binding structure of overlength; The raw material of female tooth and sub-tooth is the metal alloy mixed-powder that contains diamond particles, method with powder metallurgy cold moudling, with primary and secondary tooth connection type cutter head, disposable cold moudling is on the steel alloy matrix, and then form through the HTHP sintering, again through putting the first edge on a knife or a pair of scissors, spray paint, finishing process such as printing, packing process finished product.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples
Fig. 1 is the integral sintered saw blade of first embodiment doubly-linked type primary and secondary tooth disjunctor diamond of the present utility model.
Fig. 2 shows among Fig. 1 saw blade along the semi-section of A-A line.
Fig. 3 is the enlarged drawing of first kind of joint portion of female tooth among Fig. 2, sub-tooth and steel alloy matrix.
Fig. 4 is the enlarged drawing of second kind of joint portion of female tooth among Fig. 2, sub-tooth and steel alloy matrix.
Fig. 5 is that second embodiment four of the present utility model connects the integral sintered saw blade of type primary and secondary tooth disjunctor diamond.
The specific embodiment
The metal alloy mixed-powder that will contain diamond particles, method with powder metallurgy cold moudling, the disposable cold moudling of primary and secondary tooth connection type cutter head on the steel alloy matrix, and then is formed through the HTHP sintering, again through putting the first edge on a knife or a pair of scissors, spray paint, operations such as printing, packing process finished product.Formation has the integral sintered saw blade of primary and secondary tooth disjunctor diamond of unique texture and shape.
Female tooth 1 of this product has two or more sub-teeth 2, and has female tooth row material rhone 4 and sub-tooth row material rhone 3, helps improving the cooling of saw blade in the speed of cutting and the cutting process.
In the joint portion of steel alloy matrix and primary and secondary tooth connection type cutter head, the steel alloy matrix is with in female tooth of projection 6 embeddings and the sub-tooth, and the structure of this increase contact area makes the intensity of product increase.Fig. 3 and Fig. 4 have shown 2 kinds of embodiments about projection 6, and the steel alloy matrix can be that the tack projection embeds, and also can be that the tip projection embeds in female tooth and the sub-tooth.
In sum, adopt the integral sintered saw blade of primary and secondary tooth disjunctor diamond of the present utility model, processing cost is low, intensity is big, security is good, cutting efficiency is high.
