Programmable Solenoid Interposer Cluster Punch Head for Punching Green Ceramic

This is a programmable gang punch for punching very small apertures at a punching rate of 1500 apertures per second.

To punch a hole, the solenoid directly above the punch is energized at the start of the downstroke of the punch head assembly.

Punch stress is minimized, since the punches associated with de-energized punch selector solenoids float during a punch cycle. A punch cycle is as follows: 1. Actuator positions punch head assembly in the

"UP" position.

2. Blank is inserted between the punch head

assembly and die.

3. Punch selector solenoids directly above holes

to be punched are energized.

4. Actuator lowers punch head assembly and clamps

the blank between the die and stripper.

5. Actuator continues downward motion and holes

are punched in blank.

6. Solenoids are de-energized.

7. Actuator returns the punch head assembly to the

"UP" position.

8. Punched blank is removed or indexed for the next

punch cycle.
