I normally don't get to post customer projects but I can in this case, nothing proprietary here. I just can't tell you exactly what it's for or show the tooling.
So what do you get when you combine about 150 lbs of steel, a high quality Harbor Freight 1 ton arbor press, a NEMA 42, 4200 oz-in stepper motor, and some electronics?
If I do it right, it will become a variable speed, 600 stroke per minute, 5/16 stroke, 1/4 ton punch press.
First you're gonna say that nobody in their right mind would use a HF press for the base, and I would have to agree. It wasn't my choice, but the customer insisted since he is currently using a HF 1 ton for the job and operating it manually. He wanted to keep the manual capability in case of a mechanical or electrical breakdown so I had to design around that. It will switch over to manual in about 15 seconds, you just have to install the pinion shaft. I suspect the HF press will break long before my hardware.
Here is what it's supposed to look like when it's done.
The stack of parts. The motor weighs more than the press frame.
I'll post pictures of the build as it progresses. The first order of business will be to get the mating surfaces on the press squared up so I can use them.
