Current market, diamond saw blade has been widely used in marble, granite, concrete, pitch, pottery, glass, jewels and jade, the material cutting processing such as semiconductor, improve constantly product efficiency, reduce spillage of material, increasing economic efficiency is the direction that market is pursued jointly.
Diamond is exactly the diamond that we often say, it is a kind of mineral be made up of pure carbon.Diamond is the hardest material of occurring in nature, is therefore also just provided with many important industrial uses, as fine gtinding material, high hard cutting tool, all kinds of drill bit, wire drawing die, also by the parts as a lot of precision instrument.
Diamond saw blade, from the combination of cutter head and metallic matrix, can be divided into two large classes: the first kind be cutter head after independent sinter molding, be welded on metallic matrix; Equations of The Second Kind first to be combined with metallic matrix by cutter head by colding pressing in a mold, strong bonded both then being made by sintering.Difference according to cutter head form can be divided into the diamond saw blade of continuous cutter head type and the diamond saw blade of interval cutter head type.
Existing diamond saw blade generally adopts universal models, and its cutter head end face is generally circular arc.This cutter head is when the granite of cutting rock hardness more than 15 grades, quartzite and basalt, and cutting efficiency is extremely low, and loss is larger.
In addition, traditional diamond cutter is generally by diamond and metal dust mixing, manually carry out weighing, load mould, then carry out hot pressing or cold pressing sintering again, usually adopt the mode of welding to fix between the diamond segment of diamond saw blade used at present and matrix, not excessive diamond saw blade is when running at a high speed, processing resistance is large, cutter head easily comes off, and causes security incident, also reduces cutter head service life simultaneously.Especially, when cutting the granite of above-mentioned formation hardness more than 15 grades, quartzite and basalt, Cutting Drag is large, more needs cutterhead to be connected with cutter head fastening.
Meanwhile, diamond saw blade also deposits that operationally noise is large, cooling and the slow problem of radiating rate, and when hot operation, cutterhead also exists yielding problem.These problems are particularly outstanding when cutting high rigidity rock.
The diamond saw blade provided of the present utility model, can the continuous high-efficient ground cutting hardness grade high rigidity rock that is greater than 15, and the diamond segment overcoming existing diamond saw blade easily comes off from matrix, the bonding strength of joint face is low, the shortcoming that service life is short.
The front view of the diamond saw blade that Fig. 1 provides for the utility model embodiment; The partial enlarged drawing of the single cutter tip that Fig. 2 is the diamond saw blade shown in Fig. 1.
The diamond saw blade that the utility model provides, comprising: cutterhead 1 and the multiple cutter heads 2 being arranged on cutterhead 1 edge.
Cutterhead 1 is provided with several sawtooth 4 arranged along cutterhead 1 edge, and this sawtooth 4 is an arcwall face be in tilted layout with the joint face of cutter head 2, and described cutter head 2 is another arcwall face of tilting suitable with the arcwall face of above-mentioned inclination with the joint face of sawtooth 4.
Each sawtooth 4 of cutterhead 1 is respectively equipped with the protuberance 5 of a stop cutter head toward drag direction movement with the edge of the joint face of cutter head 2.
When diamond saw blade runs up, protuberance 5 and inclined plane all can play the effect of stop; From stressed, inclined plane change cutter head 2 stressed time fulcrum, increase cutter head 2 and cutterhead 1 intersection lifting surface area, change Impact direction simultaneously, under the acting in conjunction of protuberance 5, diamond segment is not easy to come off from cutterhead, more firmly, too increases the service life of diamond saw blade simultaneously.
In preferred embodiment of the present utility model, cutter head 2 is that cutter head 2 is more than the twice of the rear end face height of protuberance 5 away from the front end face height of protuberance 5.At cutterhead 1 in the radial direction, the top end face of protuberance 5 is a little less than the top end face of cutter head 2.
In preferred embodiment of the present utility model, protuberance 5 adopts integrated mode with sawtooth 4 and cutterhead 1.
In order to better cut high rigidity rock, cutter head 1 is from front end face to rear end face, and width increases gradually; Meanwhile, from top end face to bottom face, width increases gradually; Two triangular toothed shape that the top end face of cutter head 1 is, and the apex angle ss being greater than the Vee formation tooth near cutter head rear end face near the apex angle α of the front triangle tooth of cutter head front end face.
The apex angle α of front triangle tooth is generally taken as 130 ° ~ 160 °, and the apex angle ss of Vee formation tooth is generally 110 ° ~ 140 °.In the present embodiment, α is 150 °, and β is 120 °.
Cutter head is beloid, up-narrow and down-wide, can while guarantee its rigidity, more effective incision rock; The different rake tooth of former and later two drift angles can effectively cut high rigidity rock.
Cutterhead 1 arranges multiple sector region, and the deep-slotted chip breaker 3 of multiple arranged concentric is set respectively in each sector region.
Deep-slotted chip breaker 3 plays the effect alleviating the bulbs of pressure when cutterhead 1 expanded by heating of saw blade, can suppress the distortion of cutterhead 1, ensures cut quality.Further, deep-slotted chip breaker 3 can play certain chip removal effect in the presence of water, and can reduce the cooling of cutting noise, acceleration saw blade, can also reduce the quality of cutterhead simultaneously.
In preferred embodiment of the present utility model, sector region is set to equally distributed 3 ~ 6, and in single described sector region, deep-slotted chip breaker 3 is 3 ~ 5.
In the present embodiment, sector region is 3, and in single sector region, deep-slotted chip breaker 3 is 4.
In preferred embodiment of the present utility model, in single described sector region, the length of deep-slotted chip breaker 3 increases from inside to outside gradually, and the spacing between adjacent deep-slotted chip breaker 3 also increases from inside to outside gradually.
This structure can ensure the intensity of cutterhead 1, makes it under the duty of high strength, there will not be the situation of damage.
In preferred embodiment of the present utility model, in single described sector region, the spacing between adjacent deep-slotted chip breaker 3 is 0.03r ~ 0.1r, and the width of deep-slotted chip breaker 3 is 0.02r ~ 0.06r, and wherein r is cutter radius.
Because the applicable situation of diamond saw blade exists different, therefore also there is larger difference in its size, and diameter is not from tens centimetres to several meters etc.Therefore, the size of deep-slotted chip breaker 3 needs to design according to actual conditions, is as the criterion with the working strength not affecting saw blade.
This diamond saw blade can effectively cut high rigidity rock, and through experimental comparison, when cutting hardness is the granite of 15 grades, the more existing diamond saw blade of the utility model can improve cutting efficiency more than 30%, and the longer service life of cutter head.
This diamond saw chip architecture is simple, steady quality, easy to use, has market prospects widely.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
