Small deformation is produced, and then drives SMD former 202 to produce dither, the effect of ultrasonic antifriction is realized.
Operation principle：The automatic classification adjustable type ultrasonic vibration low friction tantalum powder punch-forming mold that the present invention is designed,
Before compacting, first by the positioning convex 302-2 extrusion fits on the blind hole 1-1-4 in die module 1 and location-plate 302 bottom of by
The die module 1 in portion is installed together with SMD former 202, in adjustment die module 1 position-arresting disk 1-4 to initial position, to
Tantalum powder is added in cavity 202-4 in SMD former 202, and sets neck 202-3 to bury along along SMD former 202 at electrode
Enter in tantalum powder to be pressed, fixed electrode with pressure pole block 5, the die module 1 at top and female die components 2 are finally arranged on one
Rise；In compacting, the automatic classification adjustable type ultrasonic vibration low friction tantalum powder punch-forming mold that the present invention is designed is positioned over
On forcing press, top die 1-5 in the die module 1 of mold bottom is set directly to be contacted with press feet boss, so that top
Die module 1 in top die 1-5 directly contacted with the pressure head of forcing press；Forcing press provides axial compressive force for mould, in axle
The position-arresting disk 1-4, top die 1-5 and dip mold 1-6 of die module 1 is set to produce axial movement in the presence of to pressure, and it is spacing
One-level glide slope 1-2-2-1s of the disk 1-4 leading arm 1-4-2 along the outer framework 1-2 track 1-2-2 set produces rotary motion,
When reaching arc convex surface 1-2-2-2 bottoms, leading arm 1-4-2 receives arc convex surface 1-2-2-2 obstruction, causes position-arresting disk
1-4, top die 1-5 and dip mold 1-6 can not continue to move downward, and now mould completes the one-level compacting of tantalum core；Lifting pressure
The pressure head of power machine, because the 1-2-2-4 of circular arc concave surface one center of circle is located at the right side of arc convex surface 1-2-2-2 bottom centre, is then limited
Position disk 1-4 eventually arrives at the 1-2-2-6 of circular arc concave surface two after entering the 1-2-2-4 of circular arc concave surface one along inclined-plane 1-2-2-5；Down force pressure
The pressure head of machine, because the 1-2-2-6 of circular arc concave surface two center of circle is located at the left side at arc convex surface 1-2-2-2 centers, then position-arresting disk 1-4
Leading arm 1-4-2 enter two grades of glide slope 1-2-2-3, realize that position-arresting disk 1-4, top die 1-5 and dip mold 1-6 continue to produce
It is axially moved, is finally completed two grades of compactings of tantalum powder.It is the piezoelectric element that is pasted onto SMD former 202 while compacting
202-5 is passed through high frequency pumping electric signal, piezoelectric element 202-5 is produced miniature deformation, and then drive SMD former 202 to produce
Dither, the inverse piezoelectric effect based on piezoelectric, make the tantalum powder in cavity 202-4 reduced in the case of dither with
Friction between cavity 202-4 inwalls, decreases the intergranular frictional force of tantalum powder, realizes that tantalum powder Density Distribution is uniformly imitated
Really.
