Hello
At that time I was in a PFE internship and I was in charge of designing a progressive tool including a cutting, bending and stamping station.; and I do quite well on the other hand I don't know some business rules for example how to choose the sights, their dimensions, the spring, the press and so on depending on the efforts applied?
The screws:
- head shape according to the available space, the company's habits;
- diameter to be calculated according to the forces and the space available;
- Length depending on the location
The springs: depending on the space available, the effort to be made
The press: you probably won't choose it, it's the company that has it in its workshop and you have to make do with it (so maybe several passes so several tools)
I would add to @stefbeno answer if steel screws to take screws with a high resistance for this you need a resistance class 10.9, 12.9...

Hello
In addition, there are many websites on which you can determine the necessary screw according to the forces, the tightening torque, etc.
One example, but there are others:

and also there is the SmartDesign application downloadable on Lynkoa!
Following my first question; Is there anyone who knows how to calculate the stroke of a flat spring?
