Abstract
A Cr-Mo 30 matrix used as diamond saw blade is in the form of circular cake and has central axle hole and open fixing hole on periphery. Laser welding is used to simplify welding process. Its advantages are saving noble metal, high productivity and low cost. Said saw blade can be used to cut stone.
Description
The invention belongs to the processing of stone technical field of tools, is a kind of 30 Cr-Mo matrix for diamond saw blade.
The diamond saw blade matrix is used for fixing diamond saw blade, is used for processing stone material.The matrix of China's diamond saw blade all adopts the manufacturing of 65Mn material, adopts resistance welding or soldering with the welding of diamond saw blade, and scolder adopts eutectic solder, uses silver solder or high phosphorus copper welding rod.Above-mentioned matrix welding subject matter is, the matrix distortion of welding back, the weldprocedure complexity, waste noble metal or non-ferrous metal etc., saw blade often occurs turning around or phenomenon of rupture in using, and promptly Han Jie intensity and durability are bad, safety coefficient is low, easily hurt sb.'s feelings, have a strong impact on production efficiency, increase the cost of diamond saw blade greatly.
It is little to the purpose of this invention is to provide a kind of matrix distortion, and weldprocedure is simple, the 30 Cr-Mo matrix for diamond saw blade that cost is low.
The object of the present invention is achieved like this: structure of the present invention is, matrix is circle and shape, and there is axis hole at the matrix center, and in matrix circumference uniform distribution plurality of fixed hole, each fixed orifices has opening, matrix adopting 30 chrome molybdenum materials, and chemical ingredients is as follows:
Fame chemical ingredients %

The present invention adopts 30 chrome molybdenum materials, has changed the use properties of diamond saw blade, can adopt advanced laser welding mode, has changed the metal inside tissue at juncture.The matrix distortion of welding back itself is little, and weldprocedure is simple, saves noble metal and non-ferrous metal, changes automatic welding into by original manual welding, has improved production efficiency greatly.In use there is grinding consumption in saw blade, does not exist to turn around and phenomenon of rupture, and welding strength and durability are good, improve the work-ing life of diamond saw blade greatly, safe and reliable under normal service condition, improved user's production efficiency, effectively reduced the cost of diamond saw blade.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Number in the figure is described as follows: 1, fixed orifices, 2, axis hole, 3, matrix.
As shown in the figure, the present invention is a circle hole shape, and there is axis hole 2 at matrix 3 centers, uniform distribution plurality of fixed hole 1 around matrix 3, and each fixed orifices 1 has opening, and matrix 3 adopts 30 chrome molybdenum materials.
The physicals of basic material of the present invention is as follows,
The tensile strength unit elongation
(MPa) (％)
450-480 28-36
Select diamond saw blade for use, with 30 Cr-Mo matrix axis holes together on the stationary shaft, diamond saw blade and 30 chromium order matrix circumference fixed orifices laser welding get final product cutting stone material.
