Abstract
A kind of high rigidity cutter for being bumped into alloy material of the utility model, including knife bar, the knife bar central eye knife bar length direction are embedded with hard alloy bar, and the length of the hard alloy bar is the 80 90% of the knife bar length.The utility model embedded hard alloy bar in knife bar improves cutter rigidity and intensity in itself, solves the problems, such as cutter because of the small rigidity of diameter and intensity difference, improves cutter life and ensure that processing accessory size requirement.
Description
Technical field
The utility model belongs to process tool technical field, more particularly to a kind of high rigidity cutter for being bumped into alloy material.
Background technology
As shown in figure 1, being turbocharger housing shown in figure, A planes are machined surface, specially for turbocharger is let out
Pressure valve surface, planarity requirements 0.02, surface roughness Ra 0.8, c-type knife mark.Due to the plane 1/3 is all hidden under flange
Side, conventional knife cannot be processed, can only design cutter and change carefully knife bar.After knife bar diameter attenuates, stress concentration and rigidity, by force
Degree, blade life is all badly damaged, and the requirement of plane cannot also ensure.
Utility model content
The utility model is intended to overcome the defect of prior art, there is provided a kind of high rigidity cutter for being bumped into alloy material.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：One kind is bumped into alloy material
High rigidity cutter, including knife bar, the knife bar central eye knife bar length direction is embedded with hard alloy bar, and the hard is closed
The length of golden bar is the 87% of the knife bar length.
Preferably, the hard alloy bar is K10 whole hard alloy bars.
Preferably, a diameter of 32mm of the knife bar, length is 123mm；A diameter of 14 mm of the hard alloy bar,
Length is 108 mm.
The utility model beneficial effect is：The utility model embedded hard alloy bar in knife bar improves cutter in itself
Rigidity and intensity, solve the problems, such as cutter because of the small rigidity of diameter and intensity difference, improve cutter life and ensure that plus
The requirement of work accessory size.
Brief description of the drawings
Fig. 1 is the partial structural diagram of turbocharger housing in the prior art；
Fig. 2 is the structural representation of the high rigidity cutter that the utility model is bumped into alloy material；
In figure：1 knife bar, 2 hard alloy bars.
Specific embodiment
The utility model is described further in conjunction with the accompanying drawings and embodiments.
A kind of high rigidity cutter for being bumped into alloy material, including knife bar, the knife bar central eye knife bar length direction insertion
There is hard alloy bar, the length of the hard alloy bar is the 87% of the knife bar length.
Wherein, as shown in Fig. 2 using the whole hard alloy bar of 108mm diameters ￠ 14 long in the present embodiment, by knife bar
After thermal expansion by hard alloy bar 2 from after press-in knife bar 1 center of the back side, shrinkage is fastened and welded, and it is total that alloy bar occupies knife bar 1
Long 87%, greatly reinforces the rigidity of cutter.
The utility model embedded hard alloy bar in knife bar improves cutter rigidity and intensity in itself, solves knife
Tool improves cutter life and ensure that processing accessory size requirement because of the small rigidity of diameter and the problem of intensity difference.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
Various modifications and alterations are made without departing from spirit and scope of the present utility model.Therefore, specification and drawings are considered as
It is illustrative and not restrictive.
