Press Tool Design - Tips for first time designer
(OP)
Designing a press tool at the moment for the first time. Any tips on how to make sure it works to a tee?
Think I need to add some guide rods so block punches line up with die. Tolerances are pretty tight.

Start over with a real die set as a substrate. That includes the guide pins, and can be stored as a unit, and bolted into a punch press or a press brake for use.

The locations are not great either and do you have enough stripping pressure?
RE: Press Tool Design - Tips for first time designer
Appreciate the feedback.
Workpiece material is Ticona Hostaform C 27021 Acetal Copolymer . It's only 0.2mm thick. I think arbor press should be sufficient.
Mike - excuse, my ignorance, for I am not up to speed on presses and dies, but what's a real die set? Is this an off the shelf set? Perhaps you send on a link to what you mean?
Ajack1 – have 2 dowels in place on die plate (Pic 5). Slight clearance on die hole in base plate so it's a loose fit. Backing plate is also screwed and doweled (Pic 6) into punch mount plate. I think I need to add bushings in the bottom of the stripper plate to help align the punches with the die. There is a clearance hole in the base plate which aligns with another clearance hole on the press body.
Can you be more specific about locations not being great? Have done a calculation and rekon springs are sufficient.

The locations are not great as nothing is fixed (all slotted) so what ties the part to the position of the three piercings?
As for the die sets this is the sort of thing I and I assume Mike was referring too.

"The locations are not great as nothing is fixed (all slotted) so what ties the part to the position of the three piercings". You mean the red parts for locating the workpiece? Problem is, tolerances on the workpiece are not very fine so need adjustment here to settle on an average location for the workpiece.

There are slight pockets on the underside of the workpiece which I think will locate on the shoulders of the die. Also, there is a profile on the workpiece which will guide the punches.
Appreciate the link.
