Description
Technical field
The utility model is related to blade processing cutting-tool engineering field, specially a kind of blade tenon roughing and semifinishing
Use rose cutter.
Background technology
Fig. 1 is a kind of tenon of aero-engine high temperature alloy circle-arc tooth tenon blade, its tenon groove position plus
Work difficulty is very big, and as the volume of series blade of aviation engine high is less and less, the material amount of going pair at tenon groove position
Cutter requirement more and more higher, should meet leaf characteristic, also ensure that cutter is durable, rigidity is strong, efficiency high.Often at present
Tenon roughing and semi-finished cutter mainly have slotting cutter, wire rod quality, T-shaped knife and rose cutter, using traditional
Slotting cutter is rough milled during with half finish-milling, and because cutter and blade shape are mismatched, the amount of causing is not clean, remains more；Use
When wire rod quality and the T-shaped knife amount of going, and the speed is caused to reduce because cutter is excessive, processing efficiency is low；Traditional rose cutter cone
Degree is smaller, typically smaller than 16 °, does not simply fail to and tenon groove position form fit, and cutter life during processing tenon groove
Short, poor rigidity.
Utility model content
Regarding to the issue above, the utility model provides a kind of blade tenon roughing and semifinishing rose cutter,
The tenon of high temperature alloy circle-arc tooth tenon blade is processed with it, rough mills higher with the efficiency of half finish-milling, processing cost is relatively low, and its
Durability and life-span are stronger.
A kind of blade tenon roughing and semifinishing rose cutter, it includes handle of a knife and the knife positioned at handle of a knife lower end
Head, the cutter head it is sophisticated spherical in shape, the cutter head is provided with helical cutting edge, it is characterised in that：The cutter head is in circular cone
Shape, the taper of the cutter head is equal to the angle between the pressure face of tenon and listrium face, and the axial length of the cutter head is more than tenon
The depth of head groove.
Further, the taper of the cutter head is 20 ° ~ 45 °.
Further, the taper of the cutter head is 45 °.
Further, the tip radius of the cutter head are 1.65mm ~ 2mm.
Further, the tip radius of the cutter head are equal to 1.65mm.
Further, the axial length of the cutter head is 9 ~ 10 mm.
Further, the axial length of the cutter head is 9.411mm.
Further, the quantity of the cutting edge is four.
The beneficial effects of the utility model are：
The cutter head of rose cutter of the present utility model is equal to pressure face and the listrium face of tenon in cone, the taper of cutter head
Between angle, the axial length of cutter head more than tenon groove depth so that rose cutter and tenon groove position
Shape matches, and amount is all uniformly gone by being walked once in the amount of going, and leaves rationally uniform surplus to finish-milling, significantly carries
Processing efficiency high, simultaneously because the taper of the traditional rose cutter of the taper ratio of rose cutter of the present utility model is big, thus
Cutter durability and cutting stability strengthen, and tool bit life reduces processing cost.

Specific embodiment
See Fig. 1-3, a kind of blade tenon roughing of the present utility model and semifinishing rose cutter, it includes handle of a knife
1 and the cutter head 2 positioned at the lower end of handle of a knife 1, cutter head 2 it is sophisticated spherical in shape, cutter head 2 is provided with helical cutting edge 3, and cutter head 2 is in circle
Taper, the taper theta of cutter head 2 is equal to the angle α between the pressure face 4 of tenon 6 and listrium face 5, and the axial length L of cutter head 2 is more than
The depth of tenon groove.
Preferably, the taper theta of cutter head 2 is 20 ° ~ 45 °, and the tip radius r of cutter head 2 is 1.65mm ~ 2mm, the axial direction of cutter head 2
Length L is 9 ~ 10 mm, and the quantity of cutting edge 3 is four.
Preferably, the taper theta of cutter head 2 is 45 °, and the tip radius r of cutter head 2 is equal to 1.65mm, the axial length L of cutter head 2
It is 9.411 mm, rose cutter overall length 50mm, a diameter of 10mm of handle of a knife 1, the quantity of cutting edge 3 is four.
Because the tenon groove shapes of the both sides of tenon 6 are inconsistent, it is therefore desirable to be processed using different rose cutters.
Brief description processes the process of blade tenon using rose cutter of the present utility model：
High-temperature alloy blades clamping is fixed on the workbench of Digit Control Machine Tool first with fixture, rose cutter clamping is existed
On the main shaft of Digit Control Machine Tool, rose cutter is carried out precisely to knife using tool setting gauge；To importing bulb in the computer of Digit Control Machine Tool
The cutting track of milling cutter, while setting technological parameter：Feed engagement be 0.02 mm ~ 0.03mm, superficial velocity be 50smm ~
60smm；Rose cutter is controlled to be projecting axially into tenon groove and rough milled to tenon groove and half finish-milling by Digit Control Machine Tool
Processing.
Tenon groove is processed using above-mentioned rose cutter, compared with existing rose cutter, processing efficiency can be carried
It is high 2 ~ 4 times；Compared with wire rod quality and T-shaped knife, processing efficiency can improve 5 ~ 8 times, significantly improve processing efficiency.
