Abstract
The invention relates to a cutter/cutter blade with a slightly formative surface, which has bonding resistance and abrasion resistance and belongs to the filed of the mechanical manufacture of mechanical engineering. The invention is characterized in that a plurality of dimple array structures are distributed in an area which is easy to generate abrasion, such as a front tool face and a rear tool face which are near the neighborhood of a cutting edge, and the dimple array structures are processed by adopting a minuteness manufacturing technique, such as electrochemical processing or laser processing, and the like so as to improve the contact situation of the cutter, cuttings and workpieces during cutting processing and prevent workpiece materials from bonding the cutter. The invention is suitable for various processing methods of the cutting processing, such as turning, milling, drilling, boring, broaching, and the like.
Description
Affiliated technical field
The present invention relates to a kind of the have anti stick of surface micro-moulding, wear-resistant cutter, belong to the mechanical manufacturing field in the mechanical engineering.
Technical background
Machining is occupied critical role in field of machining always, up to the present still is main process technology.Along with progress of science and technology, the development of high-speed machine tool and the appearance of various new materials, more and more to the research of cutter.
In machining, during the Tool in Cutting workpiece material, same workpiece, the contacted position of smear metal are loaded by very big wearing and tearing.During for example turning is processed, cutter rake face and smear metal bottom, back knife face and workpiece machined surface all have violent friction, and except front and rear knife face, attached knife face also can bear friction under the situation about having in the Milling Process.These frictions can produce frictional heat on the one hand, increase cutting force; Can aggravate the sticking cutter phenomenon of smear metal on the other hand, accelerate the wearing and tearing of cutter, influence the quality of cutter life and machined surface.Studies show that, when the bigger material of high-speed cutting some difficult-to-machine materials, especially plasticity (as titanium alloy, high-strength stainless steel), the sticking cutter phenomenon of workpiece material is very serious, often aggravate the bonding abrasion of cutter, cutter was lost efficacy rapidly, had a strong impact on working (machining) efficiency.Therefore, the contact condition of cutter and smear metal, workpiece when improving machining reduces the bonding phenomenon, makes cutter more wear-resisting, has important Research Significance.Some research is to start with from outside subsidiary conditions, adopts some advanced cooling and lubricating conditions, removes to improve cutter worker contact condition, as improves the cooling and lubricating performance of cutting fluid, adopts jet cooling and lubricating mode or the like.It is to be conceived to the material of cutter itself and structure that some researchs are also arranged; as the tool surface coating technology; promptly apply one or more layers protective layer material (TiAlN, TiN etc.) by physico-chemical process, improve the wearability and the anti-seizure performance of tool surface on the cutter material surface.At present, be applied in the production practices about some achievements in research of this respect, and obtained certain effect.But when some difficult-to-machine materials of processing, the coating material of coated cutting tool loses effect wear-resistant, protection because impact and friction meeting in being subject to processing come off very soon, suppresses the limited in one's ability of sticking cutter.
Summary of the invention
The surface of general tool for cutting machining or blade, the coating surface that comprises coated cutting tool all is smooth smooth.Can reduce the tool surface coefficient of friction although it is so, but be unfavorable for lubricant medium infiltration, film forming, performance lubrication, and during the bigger material of working plasticity, sticking cutter phenomenon is serious.For overcoming these defectives, the present invention proposes a kind of the have anti stick of surface micro-moulding, wear-resistant cutter.
Basic thought is the zone that friction easily takes place when workpiece processing tool, as near near the forward and backward knife face the cutting edge, adopts fine fabrication technique such as electrochemistry processing or Laser Processing to go out some micro-structurals (as little hole, micro-protuberance).Microstructure size is little, is evenly distributed, and does not influence the rigidity of structure of cutter own.
The invention has the beneficial effects as follows, cutter and smear metal during machining, the workpiece CONTACT WITH FRICTION, the circulation die cavity is formed on the micro-structural of tool surface and smear metal bottom, not only can store lubricant medium (cutting fluid, air, lubricated wet goods), help to improve lubricant effect, and assisting down of friction pair relative motion, form elastohydrodynamic lubrication easily, increase the bearing capacity of lubricant medium, improved the Frotteurism of cutter and workpiece, thereby can reduce to rub adverse effect the machined surface quality, suppress the sticking cutter phenomenon of workpiece material, slow down tool wear, prolong tool life, save processing cost.The present invention can be applicable to various forms of cutters, comprises the blade of integral cutter, clip type cutter etc., is applicable to the various processing methods in the machining, as turning, milling, drilling, boring, broaching etc.

Specific embodiments
As shown in Figures 1 and 2, have the anti stick of surface micro-moulding, a wear-resistant cutter for of the present invention.At it zone of wearing and tearing taking place easily, as near near the forward and backward knife face the cutting edge, adopt fine manufacturing technologies such as electrochemistry processing or Laser Processing, processes some micro-pit array structures.As dimple structure, the about 10-80 μ of single little hole diameter m, dark 5-30 μ m, adjacent little hole spacing is decided on distribution situation, is generally little hole diameter.Matrix material is by a kind of hard metal material (carbide alloy, high-speed steel), or ceramic material is formed.
In addition, the design of the geometric parameter of tool surface micro forming big or small influential to anti-seizure performance.The geometric parameter of micro forming comprises the geometry and the distribution of micro forming.Wherein geometry comprises the cross sectional shape of micro forming again, size etc., micro forming the distribute position comprise micro forming, distribution shape, density (spacing size) etc.In the mechanical seal field, existing correlative study shows that the degree of depth of dimple structure and the ratio of diameter are bigger to its frictional behaviour influence.And in the present invention, the geometric parameter of micro forming can further be optimized according to test.
