Abstract
The utility model relates to a density panel saw cuts polycrystalline diamond saw bit, the name is density panel saw cuts polycrystalline diamond saw bit, including the base member of plectane shape, be provided with tooth portion around the base member, the preceding welding of tooth portion has polycrystalline diamond layer, characterized by: the polycrystalline diamond layer divide two kinds, the branch maybe a polycrystalline diamond layer and the 2nd polycrystalline diamond layer, first kind of polycrystalline diamond layer and the 2nd polycrystalline diamond layer interval set up in tooth portion, from preceding the seeing of tooth portion, first kind of polycrystalline diamond layer outside have the structure of chamfer, second kind polycrystalline diamond layer outside portion have an orthogonal structure, the diameter of the circle that first kind of polycrystalline diamond layer outside was located is greater than the diameter of the circle located in the second kind polycrystalline diamond layer outside, the number of degrees of chamfer in first kind of polycrystalline diamond layer outside be 45 degrees, especially adaptedly saw cut the density board, still have sharpness, durable's an advantage.
Description
Technical field
The utility model relates to density board sawing polycrystalline diamond saw blade.
Background technology
Sawing density board uses hard alloy saw blade, and traditional hard alloy saw blade is owing to wearing no resistance, and saw blade passivation quickly, can not meet the sawing requirement of client far away.Generally, within every 10 hours, saw blade will be changed once, board quality difference even within 3 two hours, saw blade will be changed once.Frequently change saw blade and cause the shortcoming that labor strength is large, production efficiency is low, production cost is high, in order to strengthen the wearability of saw blade, adopt polycrystalline diamond saw blade, polycrystalline diamond saw blade comprises the matrix of circular plate type, around matrix, be provided with teeth portion, before teeth portion, be welded with polycrystalline diamond block; In prior art, because polycrystalline diamond block structured is unreasonable, such saw blade often also exists stubbed phenomenon, also have impact on the result of use of saw blade.
Summary of the invention
The purpose of this utility model be solve sawing density board time not sharp, be not suitable for density board processing problem, a kind of density board sawing polycrystalline diamond saw blade is provided.
The technical solution of the utility model is such: density board sawing polycrystalline diamond saw blade, comprise the matrix of circular plate type, teeth portion is provided with around matrix, polycrystalline diamond layer is welded with before teeth portion, it is characterized in that: described polycrystalline diamond layer divides two kinds, the first polycrystalline diamond layer and the second polycrystalline diamond layer respectively, the first polycrystalline diamond layer and the second polycrystalline diamond layer are disposed in teeth portion, before teeth portion, there is outside the first described polycrystalline diamond layer the structure of chamfering, the described rectangular structure of the second polycrystalline diamond layer outside portion tool, diameter of a circle residing outside the first polycrystalline diamond layer is greater than diameter of a circle residing outside the second polycrystalline diamond layer.
Say further, the number of degrees of the chamfering outside the first described polycrystalline diamond layer are 45 degree.
The beneficial effects of the utility model are: such polycrystalline diamond saw blade is applicable to sawing density board, also has sharp, long-lived advantage very much.The number of degrees of the chamfering outside the first described polycrystalline diamond layer are 45 degree, can realize edges of boards do not turn black, do not collapse limit, sawing linearity good, without the phenomenon of saw line, reduce the labour intensity that workman frequently changes saw blade.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation before the first polycrystalline diamond layer and the second polycrystalline diamond layer.
Fig. 3 is the part A structure for amplifying schematic diagram in Fig. 1.
Wherein: 1, matrix 2, teeth portion 3, polycrystalline diamond layer 4, the first polycrystalline diamond layer 5, second polycrystalline diamond layer 6, the first circle 7 residing for polycrystalline diamond layer outer end, the residing circle in the second polycrystalline diamond layer outer end.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, 2, shown in 3, density board sawing polycrystalline diamond saw blade, comprise the matrix 1 of circular plate type, teeth portion 2 is provided with around matrix, polycrystalline diamond layer 3 is welded with before teeth portion, it is characterized in that: described polycrystalline diamond layer divides two kinds, the first polycrystalline diamond layer 4 and the second polycrystalline diamond layer 5 respectively, the first polycrystalline diamond layer 4 and the second polycrystalline diamond layer 5 are disposed in teeth portion 2, before teeth portion, there is outside the first described polycrystalline diamond layer the structure of chamfering, namely trapezoidal structure, the described rectangular structure of the second polycrystalline diamond layer outside portion tool, namely the structure of chamfering is not had, the diameter of circle 6 residing outside the first polycrystalline diamond layer is greater than the diameter of circle 7 residing outside the second polycrystalline diamond layer, namely the outward flange of the first polycrystalline diamond layer is in the outer peripheral outside of the second polycrystalline diamond layer.Its sharpness can be ensured like this, easy chip removal.
Say further, the number of degrees of the chamfering outside the first described polycrystalline diamond layer are 45 degree.Such setting is more reasonable, result of use is better.
Claims (2)
1. density board sawing polycrystalline diamond saw blade, comprise the matrix of circular plate type, teeth portion is provided with around matrix, polycrystalline diamond layer is welded with before teeth portion, it is characterized in that: described polycrystalline diamond layer divides two kinds, the first polycrystalline diamond layer and the second polycrystalline diamond layer respectively, the first polycrystalline diamond layer and the second polycrystalline diamond layer are disposed in teeth portion, before teeth portion, there is outside the first described polycrystalline diamond layer the structure of chamfering, the described rectangular structure of the second polycrystalline diamond layer outside portion tool, diameter of a circle residing outside the first polycrystalline diamond layer is greater than diameter of a circle residing outside the second polycrystalline diamond layer.
2. polycrystalline diamond saw blade according to claim 1, is characterized in that: the number of degrees of the chamfering outside the first described polycrystalline diamond layer are 45 degree.
