Abstract
A kind of equal channel angular extrusion die for light-alloy processing, including lower bolster, former and upper punch, described former is fastened by bolts is assembled by left and right groove fixed plate and external genitalia and anus template；Leaving certain intervals between described external genitalia and anus template, gap size is consistent with specimen size；Described former is fixed by bolts on lower bolster.The utility model is to be formed by polylith template assemblies, has easily processing, and it is simple, convenient to assemble, dismantle and change, and can change the feature of former according to specimen size.
Description
Technical field
The utility model relates to the mould of a kind of light-alloy processing, particularly relates to a kind of grade passage for light-alloy processing
Angular extrusion die.
Background technology
Equal-channel Angular Pressing is that the one that recent decades grows up passes through corner large plastometric set, produces intensive shear
Effect, thus reach the purpose of crystal grain thinning and tissue.In recent ten years, domestic related personnel also wide deep carrying out
Research, as Chinese patent CN 204262083 U, CN 204093855 U all report related equal channel angular extrusion die
And construction.But its mould structure is traditional overall mould or semi-monolithic mould, mould corner difficulty of processing is relatively big, size essence
Degree is relatively hard to keep, and processing cost is higher.
Utility model content
The utility model aim to provide a kind of handling ease, low cost, installation, dismounting etc. simple, easily etc. passage turn
Angle extrusion die.
The technical solution of the utility model is: a kind of equal channel angular extrusion die for light-alloy processing, including under
Template, former and upper punch, described former is fastened by bolts is assembled by left and right groove fixed plate and external genitalia and anus template, cloudy
It is L-shaped that mould is completed rear squeezing passage, and described mould is fixed by bolts on lower bolster.
Leaving certain intervals between described external genitalia and anus template, gap size is consistent with specimen size.
Described rear negative template and front negative template effective depth difference are former groove width, i.e. HAfter-HBefore=former groove width.
Extruding corner after described external genitalia and anus template splicing is fixing is 90 °.
It is machined with the fillet of 90 °, radius relationship: R at described external genitalia and anus die plate cornerAfter-RBefore=former groove width.
Prominent the having the beneficial effects that of the utility model:
(1) mould is easy to processing；
(2) assembling of mould, dismounting, replacement operation simple and convenient；
(3) former before and after mould can be changed according to different specimen sizes, practical.
Brief description
Fig. 1 is the structural representation of the equal channel angular extrusion die for light-alloy processing described in the utility model.
Fig. 2 is squeezing passage after the equal channel angular extrusion die for light-alloy processing described in the utility model assembles
L-shaped figure.
Fig. 1 is labeled as: lower bolster the 1st, right groove fixed plate the 2nd, rear negative template the 3rd, sample the 4th, upper punch the 5th, left groove is fixed
Plate the 6th, front negative template 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described further by specific embodiment.
As it is shown in figure 1, the equal channel angular extrusion die for light-alloy processing described in the utility model, including lower mold
Plate the 1st, right groove fixed plate the 2nd, rear negative template the 3rd, sample the 4th, upper punch the 5th, left groove fixed plate 6 and front negative template 7；Concrete structure and
Connected mode is: described left groove fixed plate the 6th, right groove fixed plate the 2nd, front negative template 7 and rear negative template 3 are connected by screw solid
Surely it is combined into former；Described former screw is fastened on lower bolster 1, and described upper punch 5 is pressed down against in former groove
Sample 4.
The a whole set of assembling of equal channel angular extrusion die for light-alloy processing described in the utility model is fixed on press
On, being driven by press makes upper punch move in the L-type passage of former, thus by the part crimp to be extruded in passage,
Make extrusion crystal grain fined.
Equal channel angular extrusion die for light-alloy processing described in the utility model, described former is by several pieces of templates
Splicing and combining and forming, mould processing is simple, low cost, and assembling, unloading process are simple, convenient.
Below it is only the novel concrete application case of this experiment, any limit is not constituted to protection domain of the present utility model
System.All technical schemes using equivalence replacement, equivalents, modification etc. to be formed without departing from principle of the present utility model, all fall
Within the scope of the novel rights protection of this experiment.
