Description
Technical field
The utility model relates to powder metallurgical technology, imitates particularly to a kind of negative angle double sided slot milling insert sintering
Shape graphite boat.
Background technology
Hard alloy negative angle double sided slot milling insert cutting blade is one of indexable digital cuttings center-stage, cuts
Cutting the quality of edge quality, direct relation the performance of cutting tip, life-span etc..For negative angle double sided slot milling insert type
Product, owing to cutting edge is higher than the supporting surface of clamping in the middle of blade and it is necessary to the point of a knife fillet participating in cutting is in the highest
Point.The feature of powder metallurgy forming, product there will be the process of the ingredient melting recrystallization of binding metal in sintering process, thus
Product is caused to shrink.So in sintering process, always deforming with boat contact site or damage.In the prior art
(as shown in Figure 1), blade pressed compact 2 is all placed on being sintered on plate graphite boat 3.In sintering process, due to blade pressure
In base 2 binding metal can dissolve, the crystallization process such as precipitation, and all directions all can occur the dimensional contraction of about 18%, institute
With blade pressed compact 2 under the influence of gravity and other factors, the cutting edge contacting one side with plate graphite boat 3 will produce change
The problem such as shape, breakage, product quality cannot be guaranteed.Hard alloy shaping belongs to powder pressing forming.Negative angle double groove milling
Blade support face is less than blade cut sword.In blade pressed compact 2 production process, if be directly put on plane graphite boat 3,
It in whole sintering process, is cutting edge stress.During sintering shrinkage, cutting edge can be destroyed, and causes product rejection.
Utility model content
The purpose of this utility model is to provide a kind of profiling graphite boat, by the design of profiling graphite boat, by pressed compact
In sintering process, the position of holding capacity is become the clamping supporting surface in the middle of blade from three points of a knife, it is ensured that all cuttings of blade
Blade is in vacant state, and has the good free degree when shrinking.Efficiently solve negative angle double groove milling
The blade problem that cutting edge damages in sintering process, so that it is guaranteed that the quality of product cutting sword.
The utility model realizes above-mentioned purpose by the following technical solutions.A kind of negative angle double sided slot milling insert sintering is imitated
Shape graphite boat, the front of the substrate of graphite boat body is arranged with cylindrical supporter, and the axle of adjacent supporter
Distance between centers of tracks is slightly larger than the outer circumference diameter of blade pressed compact, and the cylindric top of supporter is corresponding with the supporting surface of blade pressed compact, blade
The supporting surface of pressed compact is placed on the cylindric top of supporter.
Further, the height of described supporter is slightly larger than nose height.
Further, the cylindric top of described supporter is plane.
Contact portion of the present utility model is face contact, and blade pressed compact is put on graphite boat imitated structure, cutting blade
It is in vacant state, not any location contacts with graphite boat body, it is ensured that in sintering process, product cutting edge is not damaged by.To produce
Product pressed compact and the contact site of graphite boat, changed into product non-cutting region by cutting blade, it is ensured that cutting blade burns whole
All in vacant state during knot, it is ensured that product quality.By Support Position on sintering boat for the change product pressed compact,
Using product non-cutting region as supporting surface, it is ensured that cutting blade is in vacant state in whole sintering process, thus protects
Demonstrate,prove product quality.

Detailed description of the invention
Below to the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.See Fig. 2 to Fig. 6, a kind of negative angle
Double sided slot milling insert sintering profiling graphite boat, the front of the substrate 11 of graphite boat body 1 is arranged with cylindrical
Supporter 12, and the axis spacing L of adjacent supporter 12 is slightly larger than the outer circumference diameter of blade pressed compact 2, the cylinder of supporter 12
Shape top is corresponding with the supporting surface 22 of blade pressed compact 2, and the supporting surface 22 of blade pressed compact 2 is positioned over the cylindric top of supporter 12
On.The height H of described supporter 12 is slightly larger than nose height h.The cylindric top of described supporter 12 is plane.
Embodiment: be provided with blade mounting holes 23 in the middle of negative angle double sided slot milling insert, outside the two ends of blade mounting holes 23
Week is the supporting surface 22 of plane, and cutting blade 21 is arranged at the periphery of supporting surface 22, and cutting blade 21 all than blade in the middle of
Supporting surface 22 high.If supported as sintering with traditional plate graphite boat 3, it is necessary to have three cutting blades 21 of one side
With the plane contact of plate graphite boat 3, and sintering temperature is the highest can reach more than 1400 DEG C in the case of, blade pressed compact
2 there will be liquid phase in sintering process, and experience is dissolved, reset the physical processes such as precipitation, cause the point of a knife contacting with boat to produce
The defects such as deformation, damage, seriously limit the batch production of this type of blade.The substrate of graphite boat body 1 of the present utility model
The bottom surface of 11 is plane, and front (substrate 11 above) is arranged with cylindrical supporter 12, and adjacent supporter 12
Axis spacing L is slightly larger than the outer circumference diameter of blade pressed compact 2, the cylindric top of supporter 12 and the supporting surface 22 of blade pressed compact 2
Correspondence, the supporting surface 22 of blade pressed compact 2 is positioned on the cylindric top of supporter 12.
According to profiling graphite boat of the present utility model.Different products, middle supporting surface 22 can have different knots
Structure and shape, it is necessary to according to the different imitated structure of different product designs, it is ensured that with profiling graphite boat, product realizes that face connects
Touch;Determine the height H of supporter 12 according to product nose height h.According to product circumscribed circle diameter, determine the axis of supporter 12
Spacing L.Ensure that the end face of supporter 12 and blade pressed compact 2 contact for face at supporting surface 22, it is ensured that support strength;Guarantee at point of a knife
In vacant state, the not natural shrinking by any external force in whole sintering process.
