Abstract
The utility model provides a diamond saw bit, belonging to the technical field of sawing tool. The diamond saw bit is composed of a diamond saw bit basal body and a cutter head which are integrally combined; the cutter head is composed of a diamond working layer and an interlayer, and the interlayer is made of the mixed powder of metal powder and carbide powder. The metal powder can be single metal powder, the mixture of more than two kinds of metal powder, or pre-alloyed powder. The diamond saw bit is reusable, high in production efficiency, and long in service life.
Description
Technical field
The utility model belongs to the cutting tools technical field, particularly a kind of diamond saw blade.
Background technology
Existing diamond saw blade is by metal powder and bortz powder is integrated processes, and becomes flat-head shape, protrude in the middle of in the sawing process, and sideslip easily, the product percent defective that processes is higher.After the saw blade end work surfaces was damaged, whole saw blade was just scrapped, and saw blade is shorter service life, and waste is serious.
The utility model content
The utility model purpose is to provide that a kind of cutter head is sharp, the diamond saw blade of long service life.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: diamond saw blade, to form by diamond saw blade substrate that is combined into one and cutter head, and cutter head is made of diamond working layers and interlayer.
Interlayer is made by metal powder and carbide powder mixed powder.
Metal powder is the compound or the pre-alloyed powder of single metal powder, two or more metal powders.
The utility model is provided with the cutter head that is made of diamond working layers and interlayer in the saw bit matrix outer end, after cutter head wore and tore because of use, the installing cutter head was promptly reusable on matrix.In the use, the interlayer appropriateness caves in and working lining appropriateness projection, can guarantee that cutter head is sharp, helps the sawing to workpiece, the production efficiency height.When interlayer is made of the mixed powder of carbide powder and metal powder, compare the interlayer that constitutes by metal powder purely, can prevent the interlayer rapid wear, interlayer and working lining rate of depreciation are complementary, thereby prevent that effectively saw blade prolongs service life because of the too dark destruction of causing cutter head inoperative destruction and saw bit matrix of interlayer recessed trench.The physicochemical property of interlayer metal powder and working lining metal powder and mechanical property should be identical or close, and the interlayer carbide powder should be identical with the working lining diamond grit or thinner, volumetric usage is no more than working lining diamond consumption.Application practice proof the utility model use cost is low, long service life.The saw blade that the saw blade that the cutter head interlayer is made by metal powder and bortz powder mixed powder is made by simple metal powder than cutter head interlayer improves about 30% service life.
Description of drawings
Fig. 1 is a cutter head structure schematic diagram in the utility model.
Fig. 2 is an another kind of cutter head structure schematic diagram in the utility model.
The specific embodiment
Embodiment 1, diamond saw blade are made up of diamond saw blade substrate that is combined into one and cutter head.(for for simplicity, body portion does not draw among the figure) as shown in Figure 1, cutter head is made of diamond working layers 1 and interlayer 2.Interlayer 2 is made by the simple metal powder.
In embodiment 2, the present embodiment, interlayer 2 is made by metal powder 3 and bortz powder 4 mixed powders.Other are with embodiment 1.
Claims (3)
1, a kind of diamond saw blade is characterized in that, is made up of diamond saw blade substrate that is combined into one and cutter head, and cutter head is made of diamond working layers and interlayer.
2, diamond saw blade as claimed in claim 1 is characterized in that, interlayer is made by metal powder and carbide powder mixed powder.
3, diamond saw blade as claimed in claim 2 is characterized in that, metal powder is the compound or the pre-alloyed powder of single metal powder, two or more metal powders.
