Abstract
The invention discloses a machining device of microstructure graphite punch for preparing a ceramic cutting tool. In the device, graphite solid liquid mixture prepared is pressed into one side of a through hole at the center of graphite substrate though extrusion forming technology till the graphite solid liquid mixture is extruded out from the other side of the through hole of the graphite substrate for the required height, and then the graphite substrate is dried so as to obtain the required microstructure graphite punch. The microstructure graphite punch machined with this method overcomes the disadvantages that the integrity of the microstructure graphite punch machined by traditional machinery is poor and the microstructure is easy to crack. Meanwhile, the microstructure punches formed by self-prepared graphite are of various kinds, materials are selected freely, independent of graphite market, and the graphite and the microstructure can be better coupled together for achieving the functions of anti-attrition and temperature reduction in the cutting of the cutting tool as well as prolonging of service life of the cutting tool, so that the development of the machining technology is promoted.
Description
Technical field
The invention belongs to the sintex technical field of the cutting in being machined, is related to micro- textured ceramic cutter stone
The preparation facilities of black punch.
Background technology
The micro- textured ceramic cutter of formed in situ is referred to during sintex hot pressed sintering, micro- by what is prepared in advance
Texture graphite punch disposably prepares micro- textured ceramic cutter as hot pressed sintering push-down head.This formed in situ is micro-
Textured ceramic cutter has certain anti-attrition, cooling, reduces the function that knife considers cementation to be worth doing, greatly prolongs the use longevity of cutter
Life.Be different from it is traditional process micro- texture in cutter rake face, micro- texture tool surface integrality of disposal molding preferably, is kept away
The destruction that secondary operation is caused to cutter is exempted from.But the preparation of existing graphite punch is confined to machining, due to graphite itself
The restriction of physical property, the graphite punch yields processed is low, and composition is single to be difficult to graphite and both micro- texture well
Advantage bring into play.
Chinese patent " application number：CN201210003617.X " reports a kind of system of micro- pond graphite self-lubricating sintex
Standby technique.Micro- pond graphite pressure head used by the technique is that the method by being machined processes a scale on graphite pressure head surface
Very little pit, then the micro- pond sintex with self-lubricating function is prepared by hot pressed sintering.Due to the physics of graphite itself
Property, machining is difficult to ensure demonstrate,proves its integrality, and the graphite machinability of different-grain diameter is inconsistent, mechanical cannot add when particle diameter is excessive
The texture of work micron level is while the material selection of graphite depends on market graphite species excessively single.
The content of the invention
For the shortcoming for overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of micro- texture graphite punch
Processing unit (plant).The device processes micro- texture graphite punch, the micro- texture graphite processed using it using extrusion forming process
Punch precision is higher, it is ensured that bulge-structure integrality, makes full use of graphite to knit with micro- while required graphite can be prepared arbitrarily
The advantage of both structures.
In order to solve the above problems, the present invention is employed the following technical solutions：A kind of micro- texture graphite punch processing unit (plant), its
It is characterised by.
（1）Graphite solidliquid mixture is injected in the device magazine.
（2）Pressure is applied to the plunger of top in magazine, makes graphite solidliquid mixture pass through graphite matrix through hole, directly
To protrusion graphite matrix lower surface desired height.
（3）Graphite matrix is taken out, it is dried, just obtained required micro- textured ceramic cutter preparation graphite convex
Mould.
（4）The preparation of micro- textured ceramic cutter is carried out using the graphite punch for preparing, you can obtain that formed in situ is micro- to be knitted
Structure graphite self-lubricating sintex.
It is common cylindrical bump using micro- texture graphite punch of present invention processing, if in actual application
The projection of other patterns is needed, also can be processed using the present invention, only required form and spacing need to be processed on graphite matrix
Through hole.
The invention has the beneficial effects as follows：Microprotrusion punch process is extrusion process, and with high precision, it is convenient etc. to control
Advantage, it is to avoid the excessively single shortcoming of traditional machining mode surface integrity difference graphite material species.By changing through hole
Size and change graphite solidliquid mixture composition, can preferably play graphite as kollag and micro- texture
Anti-attrition cooling reduces the double dominant of knife bits bonding.
