Uzgodnienie co do tego, że obliczenia bend allowance is essential in sheet metal forming. It helps in designing closiety parts by accounting for material deformation during bending processes. This article provides a clear, step-by- step guidee te calculating bend allowance.

Co z Bendem Allowance?

Bend allowance is the length of the arc of thee neutral axis during bending. It is used to determinate the total length of thee sheet metal after bending, ensuring proper fit and function of thee final part.

Parametry Key Needed

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Radius (R): Xi1; Xi1; FLT: 1 Xi3; Xi3; The inside radius of the bend.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Angle (A): Xi1; Xi1; FLT: 1 Xi3; Xi3; The bend angle in degrees.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Tickness (T): Xi1; Xi1; FLT: 1 Xi3; Xi3; The xicness of the sheet metal.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; K- faktor: Xi1; Xi1; FLT: 1 Xi3; Xi3; The ratio of the location of the neutral axis.

Etap - by- Stopień obliczenia

Follow these steps to calculate bend allowance:

Step 1: Konwersja tych bend angle to radians

Use the formula: Xi1; Xi1; FLT: 0 Xi3; Xi3; Radians = (A in defines) × (Ř/ 180) Xi1; Xi1; FLT: 1 Xi3; Xi3;.

Step 2: Oblicz te axy neutralu

Step 3: Oblicz te bend allowance

Use the formula: prevent 1; present 1; FLT: 0 presenta3; presenta3; BA = 2 × Ά× R presenta1; presenta1; pretendation 3; n presentation 1; presentation 1; presentation 1; FLT: 2 presentation 3; presentation 3; × (A in radians) / 360 presenta1; presentation 1; FLT: 3 presentation 3; presentation 3; 3;.

Badanie Calculation

For a bend with a radius of 5 mm, an angle of 90 °, a sheet squenness of 2 mm, and a K- factor of 0.3:

1. Konwersja kątowa: 90 ° × (∞ / 180) = 1,57 radianów.

2. Obliczanie wartości axii neutralu: R, Xi1; Xi1; FLT: 0, Xi3; Xi3; n, Xi1; Xi1; FLT: 1, Xi3; Xi3; = 5, 3 × 2 = 5,6 mm.

3. Obliczanie bend allowance: BA = 2 × ∞ × 5,6 × 1,57 / 360
