In drawing process, assembly jig, adjust blank space 54 etc..First, base plate 30 and middle plate 20 are by fixing
Screw 31 is fixed together, and in the drawing die locating slot that the center of 20 top surface of middle plate is arranged places drawing die 50,
Then blank holder 40 passes through the blank holder detent cover of its bottom surface together in the centre bore 41 on drawing die 50, making blank holder 40
Axle center and the axis coinciding of die cavity 51；Then, during on pressing plate 10, the pin hole of asymmetric setting is aligned in the pin bore of plate 20
Pin 80, pressing plate 10 is fastened on blank holder 40, in making on punched-type feed bin 11 on pressing plate 10 and blank holder 40
Heart hole, and die cavity 51 is coaxially disposed；Subsequently, after screw 12 passes through stage clip 13, plate in entering through the through hole on pressing plate 10
Screwed hole connection on 20, makes stage clip 13 be in compressive state.
Now mould is completed, and starts to adjust blank space 54, and blank space 54 is blank holder 40 and drawing blank
Clearance distance between 90 top surfaces, blank space 54 are generally 1/10th of 90 thickness of drawing blank.Adjust blank space 54
The step of be generally：(1) each fine motion actuator 60 is preset in into certain altitude, close micro- cupping tool, but is not put into drawing
Blank 90；(2) plastic powders are put in the punched-type feed bin 11 of 10 center of pressing plate；(3) ultrasonic drift alignment is gone forward side by side
Enter the punched-type feed bin 11 on pressing plate 10, make ultrasonic drift 70 compress the plastic powders in feed bin；(4) start ultrasonic bonder to send
Ultrasonic vibration, plastic powders are melted under ultrasonication, enter and fill up blank posting, and into the mould of drawing die 50
The overflow ducts formed between chamber 51 and blank holder 40 and drawing die 50, and flash storehouse 52 is entered by overflow ducts；(5)
Stop ultrasonic vibration, after molten plastic solidification, open mould and take out the plastics of solidification, measurement blank posting position institute is right
The thickness of the set plastic thin slice answered, blank space 54 are the difference of this thickness and 90 thickness of drawing blank；(6) adjust fine motion to promote
The height of 60 telescopic head of dynamic device, the blank space 54 needed for enabling blank holder 40 to be formed with drawing blank 90；(7) the above-mentioned mistake of repetition
Journey, until blank space 54 up to till being adjusted to require numerical value everywhere.
After having adjusted blank space 54, pressing plate 10 is opened, and blank holder 40 is removed, and drawing blank 90 is positioned over blank
In posting, then blank holder 40 and pressing plate 10 are installed.Backward punched-type feed bin 11 in addition plastic powders, by ultrasound
Drift 70 is stretched in punched-type feed bin 11 and compresses plastic powders and starts supersonic welder, makes plastic powders by ultrasonic activation
Between friction generates heat by its instant melting be molten, molten plastic as flexible punch 70 principal pressure of ultrasonic drift make
With lower pushing drawing blank 90, it is used as soft punch to drawing by the plastics of molten by the ultrasonic drift 70 of supersonic welder
Blank 90 enters die cavity 51, completes the shaping of micro- drawing product.
