Apa itu Bend Allowance?

Bend convence is the length of the arc of the netral axis during bending. Ini adalah upon upend to detere total toth of the sheet meat after bending, ensuring profit and function of finala part.

Key Parameters Needed

  • 11; Syari1; FLT: 0 Abo3; Radius (R): Ara1; FLT: 1 123; The insidee radius of the bend.
  • 1f 1f; FLT: 0 = 0 = 3. Angle (A): Well1; FLT: 1 123; Te bend angle in reveos.
  • 11; Syari1; FLT: 0 Aver3; Thickness (T): Syon1; FLT: 1 123; The thickness of the sheet meil.
  • Pertama; FLT: 0 = 33; K-factor: 501; FLT: 1 123; 1f the ratio otherlocation of the netral axis.

Step-by- Step Calculation

Ikuti langkah langkah ke kalkulate Bend Advance:

Step 1: Convert the bend angle to radians

Use the formula: 1f 1; FLT: 0 53; Radians = (A in morees) × (118) Sym1; FLT: 1 123; Aver3;; 3;.

Step 2: Callate the netral axis radius

Deterste netil axis radius:

Step 3: Calculate the bend convence

Use formula: 501; FLT: 0: 33; BA = 2 × R 1; FLT: 1 1; n 1; N 1; FLT: 2 MIS3; × (A in radians) / 360 1f; 1; FLT: 3 33333333.;.

Periksa Kalkulation

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

1.

Kalkulate netral axis radius: R 1r; FLT: 0 Aver3; n1; FLT: 1 = 5 + 0.3 × 2 = 5.6 mm.

Simpanlate bend envoce: BA = 2 × 5.6 × 1.57 / 360 0.154 meters or 154 mm.
