Description
Technical field
The utility model relates to a kind of lathe cutting tool technical field, particularly relates to a kind of special-shaped lathe tool of processing metal fiber.
Background technology
Metallic fiber, as a kind of metal material, is a kind of novel functional material grown up gradually the seventies in eighties of last century.It has very many good characteristics, as high in good electric conductivity, thermal conductivity, corrosion resistance and intensity, elastic modelling quantity advantages of higher, also there is flexibility and the spinnability of non-metallic fibers simultaneously, thus application is widely obtained, not only in the general industry departments such as chemical industry, machinery, metallurgy, weaving and daily life, and also there is very important application in high-tech sectors such as Aero-Space, atomic energy, electronics and war industrys.Along with the development of metallic fiber application these years, its performance requirement is also more and more higher, comprises the various aspects such as machinery, physics, geometry and surface topography.As the application of metallic fiber in filter paper, not only require that fiber has certain length (20 ~ 100mm), also require that its equivalent diameter is below 50 μm, under the thickness not increasing filter paper and the pliability not affecting filter paper, to improve its intensity.In order to make fiber and paper pulp have good conjugation also to require, fiber surface is coarse simultaneously.
The expansion of metallic fiber application has promoted the development of metallic fiber machining manufacture and perfect.The processing method of metal current fiber has a lot, but can be divided into three major types namely on the whole: hubbing, molten take out method and cutting method.The defect that hubbing and the molten method of taking out have it corresponding, such as moltenly takes out method technique and technical requirement is high, equipment is complicated, and and for example hubbing needs in conjunction with Technology for Heating Processing, the metallic fiber smooth surface etc. that drawing goes out.Cutting method processing metal fiber is a kind of processing mode of widely applicable, low cost.At present, main employing lathe tool Cutting Metallic Fiber, but because the rear knife face of the cutting edge of this lathe tool is for facing directly, do not match with columniform workpiece, and free-cutting saw number of teeth amount is few, cause this lathe tool in cutting process, there is following weak point: the fiber number that one-pass processes is few, and working (machining) efficiency is low; The equivalent diameter disunity of each bar fiber that one-pass processes, brings very large impact to application.
Utility model content
The utility model provides a kind of special-shaped lathe tool of processing metal fiber, which overcomes the weak point existing for lathe tool of the processing metal fiber of prior art.
The utility model solves the technical scheme that its technical problem adopts: a kind of special-shaped lathe tool of processing metal fiber, and comprise blade and be located at the cutting edge of blade leading section, this cutting edge has rake face and rear knife face, and rear knife face tilts to be provided with cutting sawtooth; Rear knife face is the arc surface adapting to workpiece, and the cutting sawtooth on this rear knife face has multiple, and is set up in parallel.
Further, described rear knife face comprises the saw-tooth-shaped cutting face being covered with described cutting sawtooth and the circular arc cutting face not being provided with cutting sawtooth, saw-tooth-shaped cutting face and circular arc cutting face are along the width of described blade and column distribution, and circular arc cutting face lags behind saw-tooth-shaped cutting face.
Further, the anterior angle of described cutting edge is more than or equal to 30 °.
Further, the side of described cutting edge is provided with louvre.
Further, the tooth depth of described each cutting sawtooth is 0.2 ~ 0.4mm, and the facewidth is 0.2 ~ 0.5mm.
Further, the width of described saw-tooth-shaped cutting face is greater than the width in described circular arc cutting face.
Compared to prior art, the utility model has following beneficial effect:
1, be designed to by the rear knife face of the cutting edge by lathe tool the arc surface adapting to workpiece, and multiple cutting sawtooth is set, when this lathe tool is cut, knife face can match with the side of cylindrical work thereafter, and cut the consistent many metal fibers of equivalent diameter, thus, the equivalent diameter that the utility model has each bar fiber that stock-removing efficiency is high, one-pass processes such as to be consistent at the feature;
2, the rear knife face of cutting edge is divided into the saw-tooth-shaped cutting face being covered with described cutting sawtooth and the circular arc cutting face not being provided with cutting sawtooth by the utility model further, and saw-tooth-shaped cutting face and circular arc cutting face are along the width of described blade and column distribution, circular arc cutting face lags behind saw-tooth-shaped cutting face, when this lathe tool is cut, one side can utilize and faced by serrated cuts, workpiece cuts many metal fibers, its circular arc cutting face can be utilized on the other hand by smooth for the rough surface finishing that workpiece after saw-tooth-shaped cutting face processing produces, so that better cut during saw-tooth-shaped cutting face feed next time,
3, the anterior angle of cutting edge is set to and is more than or equal to 30 ° by the utility model further, and the metallic fiber that can reduce to process is extruded distortion;
4, the utility model arranges louvre further on the cutting edge, and the heat produced in process can be made outwards to disperse in time, thus improves cutting-tool's used life.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But the special-shaped lathe tool of a kind of processing metal fiber of the present utility model is not limited to embodiment.
