Abstract
The utility model relates to an cubic boron nitride orifice type cutter, which consists of a cutter body and a cutter head that is fixed on the cutter body; the cutting blade is made of the sintering body of cubic boron nitride or PCBN composite sheet that is the upper surface of a hard alloy that is combined with a layer of cubic boron nitride. The cubic boron nitride orifice type cutter adopts the cutting blade which is made of ultra-hardness materials and can process high-hardness rolling materials; the production efficiency is high; the cubic boron nitride orifice type cutter is conducive to modify grinding wheels. And the composite material of cubic boron nitride and hard alloy can save materials.
Description
Technical field
The utility model relates to a kind of cutter, relates in particular to a kind of pass and die cavity cutter.
Background technology
Along with modern rolling technique development, the material that is used for high-speed rod, common wire roll is more and more harder, die cavity as ultrahigh hardness materials such as carbide alloy carbon tungsten roller ring, high-speed steel wire rolls, adopt hard alloy cutter and sintex can't process its pass, cubic boron nitride cutting tool is the preferred plan that solves carbide roll ring, high-speed steel pass.
Summary of the invention
Technical problem to be solved in the utility model is at the technical deficiency that the common pass tool bit of tradition can't be processed the die cavity of superhard roll material and ultrahigh hardness material, to provide the new material cutter of a kind of ultrahigh hardness pass and die cavity.
The utility model adopts following technical scheme to address the above problem:
A kind of cubic boron nitride pass tool bit is made of cutter hub and the cutter head that is fixed on the cutter hub, and the material of blade is cubic boron nitride sintered body or PCBN composite sheet, and the PCBN composite sheet is at the compound one deck cubic boron nitride of the upper surface of carbide alloy.
On the technique scheme basis, described cutter hub is, open a blade installation slot at the knife bar front end, a groove is established in the blade installation slot back, and an edge bearing is put in the blade installation slot bottom, and a blade is arranged on the edge bearing, the bottom of one T shape pressing plate embeds in the groove, the front end of T shape pressing plate presses blade, and bridge screw is fixed on T shape pressing plate on the knife bar, the machine of can refacing folder cubic boron nitride cutting tool.This structure is applicable to the cubic boron nitride composite blade of cubic boron nitride sintered body blade and cubic boron nitride and carbide alloy.
In order to adjust the position of refacing the back blade, an adjusting pad is also designed at described blade rear portion, can be 0.5～10 millimeter scope adjustment.
Another kind of form is a welded structure, and blade is cubic boron nitride sintered body or PCBN composite sheet, blade and cutter hub Welding Structure, and blade is welded on the cutter hub.
Described blade be shaped as abnormity, or square, or triangle, or rhombus, edge bearing and blade coupling.
Technique effect of the present utility model is as follows:
One, the blade that adopts the cubic boron nitride material of ultrahigh hardness to make can be processed high rigidity carbide alloy tungsten carbide and high speed steel material;
Two, stock-removing efficiency height, but reconditioning cutting edge roundness after the cutter passivation;
Three, adopt cubic boron nitride and carbide compound cutter, can reduce the consumption of cubic boron nitride material blade, improve the wearability of blade.
