Description
Technical field
The present invention relates to the smear metal cutter field in the metal cutting, relate in particular to a kind of non-New Type of Restricted Contact billmpse tool that waits Restricted Contact length that has.
Background technology
As far back as the eighties, restricted contact cutter has good cutting ability because of it: reduce main cutting force 15% ~ 25%, reduce centripetal force 50% ~ 60%, reduce about 100 ℃ of cutting temperatures etc., caused numerous researchers' interest in the metal cutting field.It is found that Restricted Contact length
l c When reducing to certain value, restricted contact cutter can both effectively reduce cutting force, reduces cutting temperature; Yet, when
l c When further reducing, because the intensity of point of a knife is low, serious wearing and tearing occur in cutter, and cutting force is increased sharply suddenly, and cutter life shortens.In addition, traditional restricted contact cutter mostly is confined to the Restricted Contact face of rectangular shape, namely waits Restricted Contact length.
New Type of Restricted Contact cutter of the present invention has the non-Restricted Contact length that waits at rake face.It possesses significant minimizing cutting force equally, reduces the function of cutting temperature.Contacting cutter with the conventional limited of Restricted Contact length such as having compares, this New Type of Restricted Contact cutter, owing to have the non-Restricted Contact length that waits, it can control the curl direction of smear metal, can avoid smear metal to scratch machined surface, thereby improve the surface quality of machined surface.In addition, for the Restricted Contact face of the concave shape such as V-shape, because the intensity of its main cutting edge is relatively high, and concave shape is beneficial to cutting fluid near cutting region, further reduce cutting temperature, thereby so that cutter has longer service life.
The appearance of advanced powder metallurgy forming technology becomes possibility so that preparation has the cutter of complicated rake face shape.Therefore, New Type of Restricted Contact billmpse tool of the present invention can adopt this technology to realize large batch of production.
Summary of the invention
For existing technical disadvantages, the New Type of Restricted Contact billmpse tool that the object of the present invention is to provide that a kind of cost simple in structure is low, easy to process, the life-span is long has the Restricted Contact length such as non-.
For achieving the above object, technical scheme of the present invention is as follows:
. a kind of New Type of Restricted Contact billmpse tool with non-length such as Restricted Contact such as grade, comprise cutter hub, be fixed by screws in the blade on the cutter hub, be provided with on the rake face of described blade and be groove certain geometrical shape, that be used for restriction blade and smear metal contact length, and each point and the distance between the main cutting edge on the described groove length direction are continually varyings, and this distance increases gradually towards the point of a knife direction.
The groove of this programme by have the continually varying distance between the setting of blade rake face and main cutting edge so that cutter is reducing cutting force, when reducing cutting temperature, can also be controlled the curl direction of smear metal and have more long life and intensity.
Particularly, the geometry of described groove is linear, V font or circular arc.
Simple, easy to process, the easy realization of the geometrical form that this programme provides.
Particularly, be 0.20 ~ 0.80 mm by the determined Restricted Contact length of the distance between groove and the main cutting edge.
The contact length that this programme provides both can play and reduce cutting force, reduce cutting temperature purpose, also make simultaneously blade have certain intensity, shock-resistant.
Particularly, the tangent line of each point and the angle between the main cutting edge are 5 ° ~ 45 ° on the center line of described groove or this center line.
The angular range that this programme provides can effectively be controlled the curl direction of cutting, and it is discharged by reasonable direction, protection product finished surface and be convenient to the cutting cleaning.
Particularly, described blade adopts the PM technique moulding.
Compared with prior art, the present invention has following beneficial effect: the groove of the present invention by have the continually varying distance between the setting of blade rake face and main cutting edge, and rationally control geometrical relationship between groove and the main cutting edge etc., when reducing cutting force, reduction cutting temperature, guaranteeing the blade sufficient intensity, can also control the curl direction of smear metal and have the more long life; During production, blade adopts the powder metallurgy forming technology, realizes producing in enormous quantities, and is easy to process, efficient is high.
