Abstract
The utility model relates to a polycrystalline cubic boron nitride cutting tip for processing a quenched steel cascade teeth, which comprises a cutter body and a cutter head, wherein the cutter body comprises a cutter handle and a cutter tooth part, the cutter tooth part is provided with three teeth, the three teeth and the cutter handle which are close to the teeth are respectively provided with a joined step surface, the cutter head is a cascade cutter head which is formed by joining the three teeth, and the cascade cutter head is welded on the step surface. The polycrystalline cubic boron nitride cutting tip for processing the quenched steel gear is a cascade-tooth tool comprising three blades, so a work-piece can be processed and formed at one time, and the working efficiency can be greatly improved; and in addition, the rear angle of the tool is changed to 6 to 10 degrees, the phenomenon that the tool clamps slag can be avoided, and the surface processing quality and the surface processing efficiency can be improved.
Description
Technical field
The utility model relates to the technical field that connects the tooth process tool, particularly relates to a kind of polycrystalline cubic boron nitride blade that hardened steel connects tooth processing that is used for.
Background technology
The existing tooth process tool that connects mostly uses single-point tool processing, and its working (machining) efficiency is lower, can not satisfy the requirement of client's high efficiency.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of polycrystalline cubic boron nitride blade that hardened steel connects tooth processing that is used for to be provided.
The technical scheme of the utility model is: a kind of hardened steel that is used for connects the polycrystalline cubic boron nitride blade that tooth is processed; Contain cutter hub and cutter head; Described cutter hub comprises handle of a knife portion and cutter tooth portion, and described cutter tooth portion is provided with three teeth, and three teeth are provided with the step surface that links to each other with handle of a knife portion near teeth; Described cutter head is the disjunctor cutter head that three teeth are connected and form, and this disjunctor cutter head is welded on the described step surface.
The root of described step surface is provided with the chamfering of caving in, the wide 0.3mm of this chamfering, dark 0.05mm.
The cutting edge relief angle of described disjunctor cutter head is 6 ° ~ 10 °.
Described handle of a knife portion is an isosceles triangle, and this isoceles triangle shape top is a fillet.
The angle of described teeth is 40 ° ± 5 ', described teeth root is the transition arc of radius 0.3 ± 0.05 mm.
The material of described cutter hub is a carbide alloy, and the material of described cutter head is a polycrystalline cubic boron nitride.
The beneficial effect of the utility model
The utility model be used for company's serrated knife tool that polycrystalline cubic boron nitride blade that hardened steel connects tooth processing comprises three blades, can the time processing Workpiece shaping, increased substantially operating efficiency; The relief angle of cutter becomes 6 ° ~ 10 ° in addition, can avoid the generation of tool-holder bits phenomenon, improves machined surface quality and efficient;
The root of the step surface of cutter hub is provided with the chamfering of caving in, and in the cutter hub process, makes welding polycrystalline cubic boron nitride composite sheet convenient, makes blade be adjacent to welding.Avoid the chamfering welding quality that influences not of uniform size, reduce because the excessive cutter waste product that causes of chamfering has reduced processing cost.
