I propose to built a Servo Controlled Punch Press Head.

From the web very little information is available for the basic design mechanism. Some details available are given in the attachments.

I will appreciate any information on the working principles of various commercial machines.

My basic concept is given in the attached schematic.
I have a 2" dia ball screw and nut and also a stepper controlled X and Y axis table to move the job. I am looking for a capacity of 5 tons to 10 tons.

I welcome any comments and suggestions on the concept.

We have 2 punch presses that we use to punch out the sheet metal for manufacturing AC coils. The bulk of the machine is a massive cast iron c-shaped frame weighing 10 tons that is only there to keep the upper punch lined up with the lower die. Our punch has a capacity of 40 tons pressure. If you put the wrong die in for a punch it doesn't stop. It's really cool! LOL

Hello Rossey,
It is good to see someone else interested in a CNC punch and the servo controlled striker is a missing link for the route I was attempting to go with the hand actuated press I currently have. I had thought of a kick press as a good alternative but your servo striker method might provide the needed tonnage in a small footprint. I currently operate a CNC turret press that is servo driven also, and had wondered exactly how the mechanism worked. I will be following your thread to see how this works out. Also willing to help in any way if possible.

Hello Rossey,
Have you done anymore with the servo controlled punch press idea?

have a look at amadas new series of presses they are servo driven and they have a video showing the mechanism and how its linked your not all that far off how they do it its just a pivet in place of the wedge you have and can give very high hit rates
