Abstract
A kind of diel for preparing micro-assay test specimen, the mould makes positioning more accurate, so that realization prepares the purpose of micro test piece by the extra small positioner of addition.The blank material cut is placed in the stamping station with punching, and make material rolling direction and hole axially in parallel, it is pressed downward rocking bar, the axle being connected with rocking bar drives drift to move downward by pinion and rack, stamping strip material, the test specimen of shaping is fallen, and is lifted up rocking bar, and under the auxiliary of spring force, pinion and rack drives drift to move back into original position upwards.By adding positioner, can accurate punching press micro test piece, otch is neat, no deformation, and observation finds scale error control at 2 μm or so under 3500 power microscopes.
Description
Technical field
Field is repaired the invention belongs to machine-building and fatigue damage, is related to a kind of stamping die for making micro-assay test specimen
Tool.
Background technology
Microelectron-mechanical building blocks of function often bears the effect of reciprocal load.Microelectron-mechanical is not the simple of tradition machinery
Geometry reduces, when component it is trickle to micro-or nano size after, these materials mechanics in itself, physical property and its affected by environment
Degree has significant change, it may appear that strong dimensional effect, skin effect etc..Failure of many materials under micro-nano state
Mechanism there occurs change substantially compared with macrostate, and the fatigue strength of metal mems thin film has been sent out compared with macrostate
Give birth to and significantly changed.So the fatigue damage healing properties of meagre film structural component are studied, all with important theory value and engineering
Practical significance.
Due to metal film test sample it is each to size it is small, especially only have 25 μm in a thickness direction, therefore very little is outer
Power will produce very big deformation, cause damage, deleterious effect is caused to result of the test.So as to add to a certain extent
The difficulty of test material preparation.
Present invention addition positioner, is successfully prepared required test specimen, scale error is small, otch is neat, no deformation
The content of the invention
The main object of the present invention is a kind of diel for preparing micro-assay workpiece of design, due to film sample size

The other end be connected on support (7)；Gear is combined with rack (9), the gear shaft (5) of gear is connected with rocking bar (6)；Pass through
Rotating rocker (6) drives wheel and rack (9) to be meshed, and rack (9) drives upper bed-plate (10), iron block (11), drift (3) axially
Motion, drift (3) is meshed with punching press platform (13) and realizes the punching press of micro-assay test specimen.
The mould includes big positioner, small positioner, decompressor.Its step is：
Step 1)：The blank material cut in advance is placed in the stamping station with punching, and makes material axial direction and hole
It is axially in parallel；
Step 2)：Rocking bar is pressed downward, drift is driven vertically downward by pinion and rack with rocking bar axle connected vertically
Motion；
Step 3)：Under the guiding of positioner, the accurate stamping strip material of drift, the test specimen after punching press falls on pedestal
On, blank is stayed on drift；
Step 4)：Rocking bar is lifted up, pinion and rack drives drift upward vertical movement, with the bullet on hour rack top
Spring is moved upwards due to the effect auxiliary drift of elastic force, drift is returned to original position.Remove the blank on drift.
The advantage of the invention is that：Stamping sample dimensions error is small, and otch is neat, and no deformation can meet examination
Test requirement.
