Description
Technical field
The utility model relates to metalworking technologies, specifically extrusion die technology.
Background technique
ECAP(Equal Channel Angular Pressing) it is a kind of typical SPD pure shear deformation technology, the principle of ECAP process is:
Cross sectional dimensions and the almost equal block materials of die channel size are put into lubrication good feeder connection, in plus load
Under the action of, when sample is pressed into the connection line in channel, the pure shear shear deformation of approximate ideal occurs inside sample tissue.Due to squeezing
The cross sectional shape and area for pressing forward and backward sample do not change, and can obtain very big accumulative dependent variable after multi-pass extruding.
Up to the present, people have used ECAP different materials to carry out a large amount of research.
Existing ECAP (Equal-channel Angular Pressing) mold is exactly metal block of two valves with corner channel, and ECAP (is waited logical
Road corner extrusion) technique will have good rigidity after requiring mold assembling to fix, so (equal channel angular squeezes existing ECAP
Pressure) there is a problem in mold, and the fixed position cost of manufacture of mold is higher than cost of manufacture at equal channel angular, and equal channel angular
Place is place of the mold using impaired most serious, once damage herein, whole set of die must be replaced, and thus be caused certain
Economic waste, while certain influence is also resulted in experiment process.
Summary of the invention
The purpose of the utility model is to provide a kind of replaceable equal channel angular extrusion dies.
The utility model is a kind of replaceable equal channel angular extrusion die, by mold 1, fixed die sleeve 2, fixing bolt
3, discharge port 4, hexagon socket cap head screw 5, top plate 6, mandril 7, positioning pin cylinder 8, bottom plate 9 form, and mold 1 is placed on stent
In set 2, fixing bolt 3 is fixed 2 fixation of die sleeve；Mold 1 is by the cooperation of fixing bolt 3 and fixed die sleeve 2 come rigidity
It is fixed, fixing bolt 3 is unclamped, fixed die sleeve 2 is opened, and can be taken out and more mold exchange 1.
The benificial effect of the utility model is to die fixture is separated with equal channel angular mold, once burn failure,
Fixed device only need to be unclamped can be by die change, and the pass of the extrusion die of the mold can be individually designed, both avoids in this way
Economic waste will not delay experiment process.The utility model is deformed suitable for continuous ECAP, easy to use, be readily disassembled,
Maintenance and mold changing, wherein the pass of extrusion die can be individually designed, to realize that multi-angle squeezes, or even not isometrical back pressure type squeezes
Pressure realizes the extrusion deformation in different paths, different angle by replacing different molds.It solves in mold use process
Damaged due to the problem of needing to change whole set of die at equal channel angular, avoid the waste of economy and resource, accelerate test into
Journey is able to satisfy the requirement that different angle and different paths squeeze, can be used for it is continuously extruded during, for related plastic deformation experiment
Provide powerful guarantee.
