Description
Technical field
The utility model belongs to the materials processing technology field, relates to a kind of mould, more particularly, relates to a kind of cruciform Equal Channel Angular Pressing mould that is used to prepare super fine crystal material.
Background technology
In the materials processing technology field, violent plastic deformation method (being called for short SPD) because of be by material is carried out viscous deformation repeatedly and can the conventional coarse grain material of refinement under the situation of not obvious change material profile to submicron order even nano level, be to prepare the most promising a kind of method of big block super fine crystal material and be known as by international material educational circles.Equal Channel Angular Pressing method (ECAE/ECAP) be again the most frequently used in the at present violent plastic deformation method, also be to study the most a kind of extrusion process.
The Equal Channel Angular Pressing mould that uses in the materials processing technology area research at present mainly is L shaped die cavity, promptly two passages intersect L-shaped, blank is put into access road during extruding, extrude from exit passageway, again the access road of blank being packed into then pushes repeatedly, owing to be extruded the elastic recovery and the shape distortion of material, need proofread and correct or polish extruding blank repeating when filling with substance; In addition, because the deflection that every time extruding of the Equal Channel Angular Pressing mould that uses at present produces depends primarily on the angle between two passages, seek out even, tiny super fine crystal material and often need nearly 8 times even extruding more frequently, the working (machining) efficiency that these have all seriously reduced this method has limited the industrial applications of this method.Though proposed some improved measures, as adopting extrusion moulds such as S shape, C shape, U-shaped, yet there are some defectives, single as the distortion route, in the course of processing, need to move moulds and reorientate etc.
Summary of the invention
Technical problem: the purpose of this utility model is in order to overcome more existing defectives in the prior art, compensate its defect, and provide a kind of simple in structure, easy to operate, cruciform Equal Channel Angular Pressing mould that versatility is stronger, make it can carry out the materials processing of various deformation mode, can obtain higher single pass heavy deformation, working (machining) efficiency is higher.
Technical scheme: to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of cruciform Equal Channel Angular Pressing mould that is used to prepare super fine crystal material, constitute by Equal Channel Angular Pressing die 1, drift 2, die cover plate 4, bolt 5, wherein, described Equal Channel Angular Pressing die 1 centering offers cruciform die cavity groove vertical mutually and that intersect, is mounted with drift 2 respectively in the cruciform die cavity groove; Described die cover plate 4 is connected with mould stationary platen 3 with Equal Channel Angular Pressing die 1 by bolt 5.
The tetragon that above-mentioned described Equal Channel Angular Pressing die 1 and die cover plate 4 equate for cross section.
Above-mentioned described drift 2 quantity are four, are shaped as T shape, and its cross-sectional shape is identical with cruciform die cavity groove cross-sectional shape in the Equal Channel Angular Pressing die 1.
The above-mentioned described cruciform Equal Channel Angular Pressing mould that is used to prepare super fine crystal material is that metal is made part.
Beneficial effect: a kind of cruciform Equal Channel Angular Pressing mould employing technique scheme that is used to prepare super fine crystal material of the present utility model has following advantage and effect:
1, adopt cruciform Equal Channel Angular Pressing mould, the channel cross-section size is changeable, and passage length is changeable, the motion of each drift is independently controlled, once charging can be finished required extrusion deformation degree, has reduced correction and polishing time to blank, has improved working (machining) efficiency.
2, can carry out T shape Equal Channel Angular Pressing, route A Equal Channel Angular Pressing, three kinds of modes of texturing of route C Equal Channel Angular Pressing, the mould highly versatile, applied widely, the industrial application potentiality are big.
Can provide back pressure when 3, the Equal Channel Angular Pressing mould pushes, the stressed condition of blank inside has reduced being extruded material rimose possibility when having improved extruding, especially is fit to difficult-to-deformation material, has enlarged the scope of work material.

Embodiment
Below in conjunction with accompanying drawing a kind of embodiment that is used to prepare the cruciform Equal Channel Angular Pressing mould of super fine crystal material of the present utility model is elaborated:
As depicted in figs. 1 and 2, a kind of cruciform Equal Channel Angular Pressing mould that is used to prepare super fine crystal material of the present utility model: constitute by Equal Channel Angular Pressing die 1, drift 2, die cover plate 4 and bolt 5, wherein, Equal Channel Angular Pressing die 1 centering offers cruciform die cavity groove vertical mutually and that intersect, is mounted with drift 2 respectively in the cruciform die cavity groove; Die cover plate 4 is connected with mould stationary platen 3 with Equal Channel Angular Pressing die 1 by bolt 5.
Above-mentioned described Equal Channel Angular Pressing die 1 and die cover plate 4 are the tetragon that cross section equates, drift 2 quantity are four, are shaped as T shape, and its cross-sectional shape is identical with cruciform die cavity groove cross-sectional shape in the Equal Channel Angular Pressing die 1.
Equal Channel Angular Pressing die 1 physical dimension is 130mm * 130mm * 30mm, process cruciform die cavity groove vertical mutually and that intersect by the line cutting a side centering that is of a size of 130mm * 130mm, the sectional dimension of groove is 10mm * 10mm, squeezed blank and be of a size of 9.5mm * 9.5mm * 60mm, drift 2 is 9.8mm * 9.8mm with the cross-sectional dimension of die cavity mating part, drift 2 is about 20mm with the length of die cavity mating part than squeezing blank, drift 2 is shaped as T shape, the physical dimension of die cover plate 4 is 130mm * 130mm * 20mm, Equal Channel Angular Pressing die 1, drift 2, die cover plate 4 all selects for use die steel H13 to make.
Before the extruding, cruciform die cavity groove in the isometrical angle Extruding die 1 is lubricated, by bolt 5 die cover plate 4 and Equal Channel Angular Pressing die 1 are fixed on the mould stationary platen 3, lubricated good blank is put into one of them die cavity, drift 2 is stretched into cruciform die cavity groove respectively, the motion of drift 2 can realize T shape Equal Channel Angular Pressing, route A Equal Channel Angular Pressing, three kinds of modes of texturing of route C Equal Channel Angular Pressing by the independent respectively control of hydraulic control device by the motion of controlling each drift.In principle, can carry out unlimited extruding, thereby obtain infinitely-great strain,, prepare the block body ultrafine grain material until obtaining even, tiny crystal grain.After extruding finishes, withdraw from two drifts 2 of blank place die cavity, packing into, another lubricates good blank and drift 2, the blank that promotes newly to pack into by drift 2 will push the opposite side release of good blank from die cavity, the 2 pairs of blanks of newly packing into of drift that reinstall opposite side push, and repeat said process.Therefore, adopt this mould can under the situation of not opening mould, realize serialization production.
