Many press brake operators get confused when adjusting the stroke data (or Y-axis data) on the press brake controller, especially for older models. They are unsure of the correct press brake course to set, which leads them to resort to trial and error. This is not an efficient solution.
In this article, I will demonstrate how to accurately calculate press brake stroke length using a specific formula.
See schematic diagram below. I will use his data as an example.
And the formula to calculate the stroke of the press brake is:
Stroke = Daylight – Intermediate plate height – Punch height – Die base height – (Die height – 0.5V + t)
For example:
Daylight: 370mm
Maximum travel: 100mm
Stroke = 370-120-70-75-(26-0.5*8+t) = (83-t) mm
Attention should be paid when choosing the height of the matrix:
0.5V
Easy? Try it now.
PS: If you are trying to determine the required ram depth (or tool stroke) to bend a specific angle, you can use the following online calculator.
