Equipment Overview

The WL160/4100 bending machine delivers exceptional forming efficiency for batch production of medium to large sheet metal components across industries such as electrical enclosures, construction machinery, stainless steel decoration, automotive brackets, and hardware cabinets. A real-world application example: Longwang manufacturer deployed the WL160/4100 to bend 3mm galvanized steel enclosure side panels, completing 6-step continuous bending in a single setup with consistent angle accuracy, reducing secondary straightening work by over 35% compared with older entry-level bending machines.

Key Advantages

1. Heavy-Duty Rigid Frame for Long-Term Accuracy Stability

Stress-relieved all-steel welded integral frame with excellent torsional rigidity effectively suppresses deformation during heavy-load bending, ensuring long-term precision retention under continuous mass production.

2. High-Precision Forming with Consistent Angle Quality

Equipped with a precision CNC multi-axis back-gauge system for programmable positioning, delivering accurate material alignment for multi-step continuous bending operations.

Built-in wedge-type deflection compensation mechanism automatically corrects ram deformation, ensuring stable ±0.5° bending angle accuracy across the full working length and greatly reducing secondary straightening and rework.

3. Efficient CNC System for High-Volume Production

Intuitive CNC control system supports graphical programming, multi-step bending sequence storage and one-click recall, significantly shortening programming and setup time for repeated batch orders.

Smooth synchronous drive system enables fast ram stroke adjustment and steady forming speed, boosting single-part production efficiency for medium and large sheet metal components.

4. Broad Process Versatility for Diverse Fabrication Needs

Compatible with a full range of standard upper and lower dies, supporting right-angle bending, hemming, arc bending, U-shape forming and other complex processes to meet diversified product requirements.

Adapts to common sheet metal materials including carbon steel, stainless steel, galvanized sheet and aluminum alloy, covering thin decorative panels to medium-thick structural plates.

5. Low Maintenance & Reliable Continuous Operation

Optimized drive structure features stable operation, low noise and minimal daily maintenance requirements, cutting downtime and long-term operating costs.

Accessible structural design facilitates daily die replacement and routine upkeep, lowering the skill threshold for frontline operators.

6. Operator-Friendly Safety Design

Fitted with standard safety protection devices including photoelectric safety barriers and emergency stop mechanisms to guarantee operator safety during daily production.

Ergonomic operating height and clear human-machine interface reduce fatigue during long shifts and improve overall working efficiency.

Machine Description

The DGDY-WL160/4100 CNC Bending Machine is a heavy-duty precision press brake engineered for high-accuracy sheet metal forming in medium to heavy-gauge fabrication environments. Its core engineering philosophy centers on reliable, consistent bending performance—delivered through a stress-relieved all-steel welded frame, a stable synchronous drive system, and an integrated deflection compensation mechanism, making it a workhorse for sheet metal workshops requiring both versatile forming capability and long-term operational durability.

At its core, the DGDY-WL160/4100 features 1600kN nominal bending force, a 4100mm effective bending length, and a precision CNC back-gauge system with programmable multi-axis positioning. Combined with its wedge-type deflection compensation structure, adjustable ram stroke, and compatibility with a full range of upper and lower dies, this configuration translates directly into stable ±0.5° bending angle accuracy, robust heavy-plate forming capacity, and the flexibility to process carbon steel, stainless steel, aluminum alloy, and galvanized sheet to meet diverse production requirements.
