Abstract
The utility model relates to a mixed-type dry-cutting diamond circular saw blade, which comprises bits 1 and a basal body 2, wherein each bit 1 is in a turbine tooth shape or a flat tooth shape, the bits 1 are alternately arranged on the circumference of the basal body 2, both faces of each bit in a turbine tooth shape are respectively provided with a groove 1a, the basal body 2 is provided with a plurality of rows of circular holes 2a and a U-shaped oblique groove 2b positioned between the two bits 1, and the basal body 2 is also provided with a central hole 2c and an attached hole 2d which are connected with an electric tool. The utility model has the advantages that the utility model overcomes the defects that the existing long-service-life-type and sharp-type dry-cutting saw blades are not unified, and the existing dry-cutting saw blades have the disadvantages of poor heat radiation effect, high temperature of the basal body, easy deformation, short service life, long manufacturing cycles, etc.; the utility model provides a mixed-type dry-cutting diamond circular saw blade with the advantages of sharpness, high durability, long service life, stable quality, simple fabrication, and high productive efficiency; the utility model can be widely used for sawing under the conditions of long roads and difficulty in water source supply, such as concrete roads, asphalt roads, etc.
Description
Technical field
The utility model relates to the dried diamond disc of cutting of a kind of mixed type, and particularly a kind of welded type turbo tooth and the dried diamond disc of cutting of flat tooth mixed type can be widely used in fragment of brick, the sawing of materials such as concrete, bituminous paving.
Background technology
At present, be used for construction material, finishing, road repairings etc. use saw blade more and more.In the prior art, diamond disc is when cutting fragment of brick, concrete, bituminous paving, and saw blade tip commonly used generally divides two kinds of flat tooth and turbo tooths.Cutting was more blunt when cutter head all was common flat tooth, and cutter head because the cutting area reduces, cut sharplyer during entirely for turbo tooth, but causes the life-span shorter owing to the powder of cutter head is less, so common saw blade is difficult to reach the unification of life-span type and sharp type.Long-range to road simultaneously, the water source is unfavorable provides, and adopts the wet saw blade of cutting will drag heavy large water tank, the trouble that works together, and cost is higher.Under existing situation, when having adopted the saw blades for dry cutting sawing, saw blade speed height, the workspace belongs to semi-closed state, and heat-dissipating space is little, little many of concrete thermal conductivity ratio metal blade bodies, the heat that produces during sawing mainly is delivered on the saw bit matrix, distributes by surrounding medium (air) again.Actual showing, radiating rate is limited, and the accumulation of heat raises the saw blade temperature rapidly in a short period of time.Have a strong impact on the service life of saw blade.The diamond saw blade that some special constructions are also arranged now, open structures such as air-flow cooling hole, multiple sandwich matrix as the teeth groove edge and improve the radiating condition of saw blade, but effect all is not clearly, and exist saw bit matrix intensity low, it is yielding to be heated, the manufacturing process complexity of saw blade, shortcomings such as production cycle length.
The utility model content
The purpose of this utility model is to overcome the defective and the deficiency of prior art, provides a kind of sharp durable, and the life-span is long, constant product quality, and processing technology is simple, the dried diamond disc of cutting of the mixed type that the manufacturing cycle is short, production efficiency is high.
The technical solution of the utility model is: the dried diamond disc of cutting of a kind of mixed type comprises cutter head, matrix.Cutter head is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix and cutter head weld together.Cutter head is turbine dentation and flat dentation, is that circle alternate is arranged with the matrix, and turbine dentation cutter head two sides all has groove, and matrix is provided with the groove of many row's circular holes and the oblique U-shaped between two cutter heads, and is provided with centre bore and the attached hole that is connected with electric tool.
The camber center line of described oblique U-lag is by the centre bore center of circle; The camber center line of described circular hole is by the mid point of the joint piece of the centre bore center of circle and adjacent oblique U-lag composition.
The beneficial effects of the utility model are: solved the life-span type of existing saw blades for dry cutting and the disunity of sharp type, radiating effect is not obvious, the substrate temperature height, yielding, saw life is short, manufacturing cycle is long, deficiencies such as production efficiency is low and defective, provide a kind of sharp durable, the life-span is long, is applicable to dried cutting, constant product quality, processing technology is simple, and the sawing under, the unfavorable situation about providing in water source long-range as roads such as fragment of brick, concrete, bituminous pavings is provided the diamond disc that the manufacturing cycle is short, production efficiency is high.
Description of drawings
Accompanying drawing is the dried organigram of cutting diamond disc of mixed type.
Specific embodiments
Figure of description is an enforcement optimal way of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in the figure: the dried diamond disc of cutting of a kind of mixed type comprises cutter head 1, matrix 2.Cutter head 1 is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix 2 welds together with cutter head 1.Cutter head 1 is turbine dentation and flat dentation, with matrix 2 is that circle alternate is arranged, turbine dentation cutter head two sides all has groove 1a, and matrix 2 is provided with the many rows circular hole 2a that is beneficial to heat radiation and the oblique U-lag 2b between two cutter heads 1, and is provided with centre bore 2c and the attached hole 2d that is connected with electric tool; Tiltedly the camber center line of U-lag 2b is by the centre bore center of circle; The camber center line of circular hole 2a is by the mid point of the joint piece of the centre bore center of circle and adjacent oblique U-lag 2b composition.
