CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

When doing sheet metal processing, the main process is bending, the main machinery is hydraulic press brake. Bending seems simple, but there are many means and tricks in it. The following is to introduce the various bending techniques of sheet metal bending. Tool Graphics software CAD Method and Steps: 1. The general bending 1:(R=0, θ=90°) L=A+B+K 1. When 0¢T£0.3, K'=0 2. For the iron material:(eg., GI, SGCC, SECC, CRS, SPTE, SUS, etc.) a. 0.3¢T¢1.5, K'=0.4T b. 1.5£T¢2.5, K'=0.35T c. T/2.5, K'=0.3T 3. SUS  T>0.3  K'=0.25T 4. For other nonferrous materials such as AL,CU: T$0.3,  K'=0.5T 2. The general bending 2: (R≠0   θ=90°) L=A+B+K’ K is the neutral arc length. 1. T¢1.5,  K'=0.5T 2. T/1.5, K'=0.4T Note: when using bending knife processing R£2.0, R=0° 3. The general bending 3: (R=0 θ≠90°) L=A+B+K’ 1. T£0.3, K'=0 2. T$0.3, K'=(u/90)*K Note: K is the amount of compensation when 90° . 4. The general bending 4: (R≠0 θ≠90°) L=A+B+ K’ 1. T...
