Abstract
The diamond saw blade with long service life includes one base body and several radial bits in the outer edge of the base body. Between each two adjacent bits, there is one notch extending to the center of the base body, and the notch includes one circular hole of 9 mm diameter and one connected V-opening, with the central line of the V-opening and the radial extension line through the center of the circular hole forming one angle of 7.5-8.5 deg, preferably 4.5-5.5 deg. The present invention is suitable for cutting non-metal material, such as granite.
Description
Technical field
The present invention relates to a kind of diamond saw blade, it is used for the cutting non-metal material.
Background technology
Diamond saw blade is used for the cutting non-metal material, and particularly stone slab is for known, and diamond saw blade is as how many very big processing costs that influence of its unit are consumption of consumable accessory.Known circular diamond saw blade comprises a disc matrix and evenly is located at some cutter heads compositions of matrix radial outside, and be provided with groove between every adjacent two cutter heads, described groove radially extends to body portion, present widely used groove has two kinds, a kind of is " U " type, another kind is commonly called as key-hole type, but unfavorable situations such as bottom portion of groove cracking even the fracture of cutter head root in use often take place in this diamond saw blade, cause shorten service life, processing cost rises, even the cutter head that fracture takes place flies out and causes industrial accident.On October 11st, 2000, the Chinese patent CN2400253 of bulletin disclosed a kind of band tooth diamond saw blade, it is for solving aforementioned technical problem, front and back at saw blade is provided with the layer of metal net respectively, and nationality is strengthened the matrix of saw blade and the adhesion and the saw blade bending strength of cutter head by this wire netting.But the discharge that this kind structure not only can the overslaugh sawdust, and the frictional force between saw blade and the workpiece is increased, power consumption increases.
Summary of the invention
The diamond saw blade that the purpose of this invention is to provide a kind of long service life.
The technical solution adopted in the present invention is such: a kind of diamond saw blade, comprise that matrix reaches some cutter heads of evenly being located at the matrix radial outside, be provided with the groove that extends to the matrix core between described every adjacent two cutter heads, the described groove that is positioned at body portion along matrix radially bearing of trend comprise circular hole and connect " V " type opening of described circular hole, the diameter of described circular hole is 9mm, and the matrix extend radially wire clamp angle at described " V " type open centre line and place, circular hole center is 7.5 °～8.5 °.
Above-mentioned diamond saw blade, the matrix extend radially wire clamp angle at described " V " type open centre line and place, circular hole center is 8 °.
Above-mentioned diamond saw blade, two sidewalls of described " V " type opening and the angle of its center line are respectively 4.5 °～5.5 °.
Above-mentioned diamond saw blade, two sidewalls of described " V " type opening and the angle of its center line are respectively 5 °.
By adopting the aforementioned techniques scheme, in the saw blade process is installed, make the cut direction angle at " V " type open centre line of cutting point position and cutting point place less than 90 °, thereby in working angles, make the stress distribution of sawtooth more even, reduce the maximum stress value of bottom land, prevent unfavorable situations such as bottom portion of groove generation crackle or cutter head fracture, prolong the service life of diamond saw blade.
Description of drawings
Fig. 1 is the embodiment front view;
Fig. 2 is an A part enlarged drawing among Fig. 1;
The specific embodiment
With reference to figure 1, Fig. 2, embodiment discloses a kind of diamond saw blade, 28 cutter heads 2 that it comprises matrix 1 and evenly is located at matrix 1 radial outside, be provided with the groove 3 that extends to matrix 1 core between described every adjacent two cutter heads 2, the described groove 3 that is positioned at matrix 1 part along matrix 1 radially bearing of trend comprise circular hole 31 and connect " V " type opening 32 of described circular hole 31, the diameter of described circular hole 31 is 9mm, described " V " type opening 32 is actually matrix 1 and is cut the opening that the back forms, two sidewalls of definition " V " type opening 32 are sidewall 321 and sidewall 322, the matrix 1 extend radially wire clamp angle at described " V " type opening 32 center lines and place, circular hole 31 center of circle is 8 °, and the angle of described sidewall 321 and sidewall 322 and " V " type open centre line is for being respectively 5 °.When installing, install as cutting direction according to the direction shown in the arrow among Fig. 1 and Fig. 2, make the angle of " V " type open centre line of cutting point position and cut direction less than 90 °, thereby disperse cutting stress to greatest extent, prolong the service life of diamond saw blade.
In the above-described embodiments; based on same inventive concept; the diameter that changes circular hole 31 in proper range should belong to technical scheme of the present invention and being equal to mutually as making 8.8mm or 9.2mm into; the protection domain that belongs to institute of the present invention letter lid; the matrix extend radially wire clamp angle at described " V " type open centre line and place, circular hole center is all feasible and be optimum value with 8 ° in 7.5 °～8.5 ° gamuts; in 4.5 °～5.5 ° scopes of angle of two sidewalls of described " V " type opening and its center line can, can do corresponding change according to the matrix diameter.
Claims (4)
1, a kind of diamond saw blade, comprise that matrix reaches some cutter heads of evenly being located at the matrix radial outside, be provided with the groove that extends to the matrix core between described every adjacent two cutter heads, it is characterized in that: the described groove that is positioned at body portion along matrix radially bearing of trend comprise circular hole and connect " V " type opening of described circular hole, the diameter of described circular hole is 9mm, and the matrix extend radially wire clamp angle at described " V " type open centre line and place, circular hole center is 7.5 °～8.5 °.
2, diamond saw blade according to claim 1 is characterized in that: the matrix extend radially wire clamp angle at described " V " type open centre line and place, circular hole center is 8 °.
