How to Determine the Tonnage of the Trimming Press?

The trimming press is used for trimming and punching. The required tonnage of the trimming press can be calculated as follows: P-cut=1.6δbL (2.5h+B) The required press tonnage for punching: P-hole=1.6δbL(2.5H+B) P-cut—trimming force required for trimming (N) P-hole—punching force required for punching (N) δb—material strength limit (MPa) L—circumference of trimming and punching of forgings (mm) H—the …
