Abstract
The utility model relates to a diamond circular saw blade and a diamond tool, in particular to a caking type diamond cutting blade, which aims to be wear-resistant, long in service life and high in safety and stability. In order to achieve the purpose, the diamond cutting blade comprises a circular diamond cutter and working tapes of a caking type cutter bit, a hole is arranged at the center of the circular diamond cutter, and the working tapes are uniformly brazed at the peripheral end of the cutter. The caking type diamond cutting blade is characterized in that the caking type cutter bit rotates around an axis according to a normal line cutting arc of the cutting blade, so that at least two metal powder arc-shaped cutting regions mixed with diamond coarse ground powder are formed on a longitudinal section of the cutter bit, and the caking type cutter bit is formed via processes such as cold pressing, sintering (hydrogen reduction) and the like. The caking type diamond cutting blade has the advantages that chips generated in high-speed cutting and grinding processes of a saw blade can be stored in a groove naturally formed on a substrate of the cutter bit and are released, twice friction of the chips to a cutting region of the cutter is reduced, the service lives of the cutter bit and the saw blade are prolonged, and the caking type diamond cutting blade is widely applied to sawing various hard materials such as stones and the like.
Description
Technical field
The utility model relates to a kind of diamond disc and diamond tool, and particularly a kind of caking formula diamond tool is widely used in the sawing of hard materials such as various stone materials.
Background technology
In the prior art, the cutting element of crisp hard material such as stone material, adopting the sawing processing of multi-block type diamond disc is the main mode of present processing of stone, this diamond disc, form by caking formula diamond segment and the soldering of saw blade cutter hub, have evenly tank spaced apart on the circumference of saw blade cutter hub, make and form evenly sawtooth end spaced apart on the circumference of saw bit matrix, diamond segment is welded on the sawtooth end, the diamond disc of this structure, mix saw technology with respect to traditional metal powder with diamond, greatly improved working (machining) efficiency.
But, in the grinding process,, taking place that stone material collapses the limit, cutter head collapses phenomenons such as tooth, causes cutting speed slow because during the saw blade high-speed cutting, the smear metal meeting makes cutter head wearing and tearing occur, and then produces shake, cutting quality is poor, influences cutting blade service life.
The serviceability main path that improves cutter head at present is to adopt the coarse granule diamond of high kind, manufacturing cost height.
Summary of the invention
The purpose of this utility model is: overcome the defective and the deficiency of multi-block type diamond segment prior art, provide a kind of wear-resistant, the life-span is long, the cutting piece made from diamond that security and stability is strong.
Concrete technical scheme is: a kind of cutting piece made from diamond, and circular cutter hub just and the work zone of even soldering at the cutter head of cutter hub periphery end that it comprises center drilling leave the mouth of a river between every group of cutter head, and it is characterized in that: described cutter head is multi-block type.
Described being mixed with in the adamantine cutter head, press cutting sequence, normal cutting arc according to pitch cutting, the direct-axis line is rotated in the cutter head vertical section and forms at least two cutting region, matrix behind the diamond arc cutting area of described cutter head, because its hardness is significantly less than cutting area, at work through the friction of smear metal, wash away nature and formed and deposit bits chip removal groove.
The beneficial effects of the utility model are: the smear metal that produces in saw blade high-speed cutting, the grinding process can be stored in each groove that forms on the cutter head matrix and discharge, and has reduced twice friction of smear metal to the cutter hub cutting region, thereby has prolonged the service life of saw blade.

The specific embodiment
For more clearly understanding architectural feature of the present utility model, the utility model is further elaborated below in conjunction with accompanying drawing.
As shown in Figure 1, concrete technical scheme of the present utility model is: a kind of cutting piece made from diamond, it comprises the circular cutter hub 1 just and the work zone 3 of even soldering at the cutter head 2 of cutter hub periphery end of center drilling, cutter hub 1 periphery end offers the evenly cup-shaped mouth of a river 4 spaced apart, make and form evenly sawtooth end spaced apart on the circumference of saw blade cutter hub 1, described multi-block type diamond segment 2 is brazed on the sawtooth end, it is characterized in that: described cutter head 2 mix by the metal dust that is mixed with the diamond grits after cold pressing, sintering technologies such as (hydrogen reducings) and making.
In the described cutter head 2 that is mixed with the diamond grits, its diamond grits 21 is in metal dust 22, press cutting sequence, according to calculating, normal cutting arc 5 according to cutting blade, direct-axis line 6 is rotated in cutter head 2 vertical sections and forms at least two cutting region 23, and described normal cutting arc 5 can be done corresponding change according to cutter hub 1 diameter; Metal dust 22 matrixes behind the diamond arc cutting area 23 of described cutter head 2, because its hardness is significantly less than cutting area, at work through the friction of smear metal, wash away nature and formed groove 24, the smear metal that saw blade is produced in high-speed cutting, grinding process, because of there being groove 24 to deposit bits, more strengthened the chip removal ability; Referring to Fig. 2.
As shown in Figure 3, described caking formula cutter head 2, have by order row more than six layers 22 layers of metal powder tailpieces being mixed with diamond grits 21 cutting region 23 through cold pressing, sintering technologies such as (hydrogen reducings) and making: its processing technology: use the vacuum implantation, successively in the model of setting, implant the diamond grits of arranging by design 21; Be ground floor diamond grits 21,22 layers in back layer of metal powder successively replaces, by setting requirement, behind last one deck diamond grits 21, through cold pressing, sintering technologies such as (hydrogen reducings) and making.
Diamond grits 21 in the cutter head 2 of described multi-block type in the diamond arc cutting area 23, more reasonable for design, reduce product cost, or according to close back white-out row before joint piece labial surface 25 orders.
In the above-described embodiments, based on same utility model design, in suitable range of application, or the diamond grits arrangement of change multi-block type cutter head vertical section cutting region, can reduce side-friction force, increased the bulk strength of cutter head, increased the cutter head life-span.
Caking formula cutting piece made from diamond of the present utility model, the scientific and rational cutting region design of its caking formula cutter head is compared with original multi-block type cutting blade that leaves the mouth of a river to the greatest extent, through facts have proved, efficient improves more than 20%, and energy consumption significantly reduces, and has prolonged the service time of cutting blade greatly.
The above only is a preferred embodiment of the present utility model, does not limit practical range of the present utility model, but the equivalent variations that these features are done and improvement etc. are all protection domain of the present utility model and contain.
