CINCINNATI PRESS BRAKE

BENDING ON A CINCINNATI PRESS BRAKE

RATING

All CINCINNATI press brakes are rated for maximum bending pressure, or tonnage. Tonnage can then be converted into ending capacities through an understanding of basic factors affecting the formability of metal. Bending factors, or “rules of thumb,” for press brake forming are based on using mild steel (60,000 psi maximum tensile strength).

Vee Die Opening and Inside Radius

The recommended vee die opening for mild steel up to 1/2” (.500”) thick is eight times the metal thickness. For thicker than 1/2” mild steel, it may be necessary to increase the vee die opening up to ten times the material thickness to minimize cracking of the material. To determine the vee opening for a simple 90° bend, multiply the metal thickness by eight. The answer is then rounded to the next higher 1/8” figure. For example: 14ga. (.075”) x 8 = .600”. This is rounded to a 5/8” vee opening. The inside radius of a bend in mild steel is about 5/32” (.156”) x the vee die opening regardless of the gauge of metal being formed. This figure was determined by measuring formed samples bent over various die openings. To illustrate: If a 1/8” (.125”) sheet and a 1/4” (.250”) plate are formed over a 2” vee die, each will have the same inside radius of approximately 5/16” (.312”).
