Abstract
The utility model relates to a cutter technical field, concretely relates to combined type PCD break bar. Including break bar body and the mounting hole that sets up along the axle center of break bar main part, the groove is cut by the row of being equipped with on the both ends face of break bar body, and the break bar body includes the hard alloy layer of the middle PCD blade part both sides of middle PCD blade subtotal, and middle PCD blade part includes to form along circumference respectively on the outer peripheral face of break bar body follows inclined cutting face and the cutting edge of axial both ends side towards the inboard diameter increase of axial. The utility model discloses the beneficial effect who produces is: the break bar body is partial sharp nature and the wearability of having guaranteed the break bar blade of middle PCD blade, and the hard alloy layer of both sides has improved the machinability of break bar, has reduced the break bar processing cost, and break bar body both ends face sets up to arrange cuts the groove, can blow away the smear metal that produces simultaneously among the cutting process, has improved the stability of break bar operation in -process cutting.
Description
Technical field
The utility model relates to cutting-tool engineering field, is specifically related to a kind of combined type PCD break bar.
Background technology
At present, the diamond break bar of glass-cutting is monoblock type PCD material, to be fixed on knife rest by break bar to cut by cutter shaft.The wearability that PCD is higher causes the efficiency when selecting skive to carry out break bar grinding lower, and the abrasion of skive are larger.When using scribing wheel to cut glass, the powder of cut glass can be collected near cutter, can bring certain resistance, be unfavorable for that glass-cutting is processed to glass cutter wheel.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of combined type PCD break bar, under the prerequisite ensureing cutting reliability, improving the machinability of break bar, cut down finished cost.
The utility model is by the following technical solutions: a kind of combined type PCD break bar, the installing hole comprising break bar body and arrange along the axle center of break bar main body, the both ends of the surface of described break bar body are provided with row and cut groove, break bar body comprises the hard alloy layer of middle PCD cutting edge portion and middle PCD cutting edge portion both sides, and the outer peripheral face that middle PCD cutting edge portion is included in break bar body circumferentially forms the inclined cutting surfaces and cutting edge that increase from side, axial both ends towards axial inside diameter respectively.
Described break bar body is provided with the inclined-plane tilted towards cutting edge direction be connected with cutting face.
Described cutting face is connected with inclined-plane by circular arc chamfered edge.
The bottom land that described row cuts groove is the inclined-plane tilted towards cutting edge direction.
The shape that described row cuts groove is flaabellum shape.
Sintering is combined between described middle PCD cutting edge portion and hard alloy layer.
Described middle PCD cutting edge portion accounts for 1/3 ~ 1/2 of break bar body thickness.
The beneficial effect that the utility model produces is: break bar body both ends of the surface arrange row and cut groove, the chip produced in cutting process can be blown away simultaneously, improve the stability of cutting in break bar operation process, break bar body is sharpness and the wearability that middle PCD cutting edge portion ensure that break bar cutting edge, the hard alloy layer of both sides improves the machinability of break bar, reduces break bar processing cost.
