Hydraulic Torsion Bar CNC Press Brake for Sheet Metal Bending
Modular Fast Tooling & Controller Flexibility: Standard quick-acting clamps for swift upper punch changeovers, 42CrMo precision tooling, optional mechanical crowning, and multiple CNC controllers including TP10S, DELEM DA41T, ESTUN E310P, or CtbTouch8.
Overview & Torsion Bar Synchronization
The Hydraulic Torsion Bar CNC Press Brake (WC67K Series) is an economical, highly reliable, and heavy-duty sheet metal bending solution. The machine frame undergoes integral processing by large floor boring and milling machines to ensure permanent frame accuracy and squareness under high pressure.
Adopting a solid forged steel torsion shaft mechanical synchronization system, the mechanism links both cylinder ends positively, guaranteeing that ram motion remains completely parallel to the worktable even during unbalanced off-center bending operations.
Popular Model Configurations & Colors
Available across varied bending lengths, throat depths, and frame tonnages to accommodate diverse sheet metal workshops:
Model 4016: 40T / 1600 mm
Compact workshop size with blue & white finish, pendant TP10S touchscreen CNC console, and mobile support arms.
Model 6325: 63T / 2500 mm
Heavy-duty industrial red & white series featuring standard quick clamping punch holders and rigid deep throat frame.
Model 8032: 80T / 3200 mm
Full-size architectural duct & sheet bending bed with green & white livery, extended linear guide rail, and multi-finger backgauge.
Precision Tooling & Backgauge Mechanics
- Rapid Clamping System: Standard equipped fast clamp enables rapid tool replacement in minutes, reducing labor fatigue and eliminating punch dropping risk.
- Segmented Punch & Multi-V Lower Die: Top punch segmented into modular lengths (100, 10, 40, 50, 20, 15, 200 mm, etc.) with customizable left/right horns for box folding and complex profiles.
- Servo Ball Screw Backgauge: Precision linear guides and ball screw drive ensure rapid, micro-precise stop finger indexing (X-axis).
- Mechanical Crowning Compensation: Optional CNC or manual wedge deflection crowning device cancels ram deflections, ensuring straight angles across the entire sheet length.
