Description

Blade and cutter
Technical field
This utility model relates to the blade in a kind of groove installing handle of a knife for being placed in cutter, and described cutter is especially Routing tool.It addition, this utility model relates to a kind of cutter.
Background technology
The processing on free shape surface just as being used especially in forging die manufacture and Making mold or space flight and aviation Typically carrying out by routing tool, it moulds spherical or torus shape when turning round around its center axis.Lead in the case Often using twolip detachable blade to come milling and drilling, it is placed in installation handle of a knife between two parties, and this installation handle of a knife has for laying Blade and have the side groove of manhole, securing member is screwed through this through hole to position this blade.Routing tool by with In metal material and the roughing of nonmetallic materials or polish.
In the case, it is not only especially relevant to the sheet shape of standard insert, relief angle and sheet thickness DIN ISO1832. Be different from sheet shape described in DIN ISO1832 or DIN ISO6987 (according to prior art sometimes at its back side or side face and Other not suffering from such as macroshape by grinding in the local in its cutting front after the sintering is processed except material), from existing There is the routing tool blade known in technology in its side face (i.e. the back side) region or removed by machinery along placed side and cutting front Material secondary operations.
It is different from such as DIN ISO1832 or DIN ISO6987 institute it addition, the blade of routing tool fixes aspect at blade The blade stated.Blade according to DIN ISO1832 is fixed and realizes by screw, or clamping utilizes pincers or pin to realize, Thus here this blade is compacted on bearing in side, and the blade of routing tool is wrapping between the first and second ends It is fixed in the groove installing handle of a knife of cutter by trip bolt containing in the case of insert through hole and end inner via hole, thus occurs Two-side supporting.
By the grinding performed by disclosed routing tool blade in the prior art, may occur in cracking along blade, Tipping, scar tumor or the defect of the tissue injury's form in internal stress variation, it is by the mill caused because of thermal transformation Haircut heat causes.Equally, cooling lubricant help under perform grinding typically result in powder metallurgically manufacturing with cobalt for combine The corrosion of the cutter material of phase.This corrosion induces one because occurring the so-called i.e. cobalt content of cobalt leaching to wash out to note in described blade Meaning.The aspect of performance that the cracking of blade, tipping or scar neoplasia or tissue injury and cobalt are leached at blade shows substantially.Example As, it is impossible to get rid of in work in the near future with regard to premature failure.
Another shortcoming is also had in addition to the sky high cost that the operation additionally completed when in grinding is occurred, because material Removing causes the efficiency for cutter material makes full use of to reduce.Such as, after grinding, the corresponding of cutter material slurry is needed Remove or regeneration.
At EP 0 523 404 B1, DE 103 08 036, B4 and DE 600 06 839 T2 describes blade, wherein It is provided with the blade of 180 ° of staggering.By unclamping trip bolt, can be replaced with old blade or indexing, in order to will be at this blade On another cutting portion come into operation.
The pottery in flying knife sheet form that DE 10 2,011 087 507 A1 is described a kind of sintering by blank and manufactures Porcelain blade, it has to be respectively provided with and enters end face and the bottom surface of placed side in cutter cutter holder for clamping and connect end face and the end The side in face and the blade for workpiece machining.Just it is being adjacent to the cutting around placed side that can be provided around with blade Face, wherein, described side, blade and cutting front are constituted by sintering formed sintering cortex, and do not run into by except material The damage processed and cause, only placed side accept except material processing and are not that the sintering cortex generated by sintering is constituted.
Although really indicating the advantageous effect of sintering cortex in DE 10 2,011 087 507 A1, wherein claim it Wearability can be improved.But consider because looking that following surface roughness occurs in the sintering cortex of glittering or dull gray: it is being cut Cut the course of processing is possible especially in blade edge region hinder chip drain.Disadvantageous blade face performance is now facilitated blade and is treated Remove the attachment between material, this formation causing having the cutter of scar tumor.In addition to being prone to attachment, sintered blank layer and above-mentioned cobalt Leach that also result in can the relevant problem of coated infiltration to blade material.Weak wettability is by CVD method or PVD method Coated blade again results in the performance weakened.
Utility model content
Therefore, task of the present utility model is to provide the installation handle of a knife for being placed in cutter especially routing tool Blade in groove, it can manufacture and ensure the long life of blade at low cost.
According to this utility model, this task will be completed by a kind of blade.Described blade is used for being placed in cutter especially Being in the groove installing handle of a knife of routing tool, described blade has at least one blade, cutting front and back and placed side, Also having for this blade being fastened through hole in the cell by trip bolt, wherein, this blade passes through cutter material powder Compacting and sintering make, and at least one blade described, cutting front and back be retained in sintering state.
Preferably, this blade can meet according to the size of grade of tolerance J according to DIN ISO1832, K, L, M and N steady Qualitative, wherein, the tolerance relevant to diameter and blade lengths can be ± 0.05 millimeter.
Preferably, the through hole of this blade can have and not experience the circular cross section being processed further after sintering.
Preferably, this cutter material powder can have one or more in materials described below:
-WC-Co hard metal,
-WC-(Ti/Ta/Nb) C-Co hard metal,
-TiC/TiN-Co/Ni ceramic metal,
-PM-HSS;
-cutter ceramic material.
That is, according to this utility model, at least one blade, cutting front and back are retained under sintering state.This practicality Therefore novel feature is by using direct pressing to optimise cutter material resource, this significantly reduces this practicality new The manufacturing cost of type blade.In some application scenario, such as when blade is provided for roughing, placed side is (i.e. and blade Two faces that thickness is adjacent) also can be retained under sintering state.But according to corresponding requirement, the two placed side can also be by Except material is processed.Because blade placed side do not get involved working angles subsequently and thus unrelated with real blade cut function, therefore The work surface of this utility model blade is not processed except material in the case.
