1. Overall Drive Architecture: Permanent Magnet Servo Direct Drive, Eliminating Hydraulic Transmission Systems

Traditional hydraulic press brakes rely on a hydraulic power unit, cylinders, and sealed oil circuits to transmit power, whereas Zhenghao Youbang's all-electric servo CNC press brake adoptsDual permanent magnet synchronous servo motor paired with a high-precision ball screwA direct-drive slider mechanical transmission structure eliminates hydraulic oil and pump station components throughout, fundamentally transforming power transmission at the foundational level.

Independent servo motors on the left and right sides drive their respective lead screws, synchronized via a balance control program to deliver distributed power output. The transmission assembly features high-precision ground ball screws paired with planetary gear reducers, achieving a mechanical efficiency of up to 98% and significantly improving dynamic response. Together with the CNC system, the entire drive unit forms a complete closed-loop control chain.All-Electric Press BrakeThe core technology differentiator from hydraulic models.

The chassis frame is constructed from Q355 high-strength steel plates via integral welding. Post-welding, the unit undergoes dual stress-relief treatment using high-temperature tempering and high-frequency vibration to eliminate internal stresses. This ensures minimal deformation even under prolonged high-frequency bending operations, providing a stable mounting base for precise all-electric power transmission.Precision Bending MachineBasic rigid process assurance.

II. Full Closed-Loop Position Feedback and Precision Control Technology

Equipped with high-precision magnetic scale components for full-range position sensing, the device continuously captures travel data from both sides of the slider. This real-time signal is transmitted to the CNC host, establishing a triple closed-loop control system: CNC System – Servo Drive – Magnetic Scale.

Slider repeatability error is minimized, ensuring consistent bend angles. For spring-back-prone materials such as stainless steel, aluminum alloy, titanium alloy, and high-strength thin sheets, the system features a built-in material database and adaptive spring-back compensation algorithm. After operators input sheet thickness, yield strength, and length, the system automatically calculates bending stroke and downforce, eliminating the need for trial-and-error adjustments.

The workbench integrates a mechanical deflection compensation module. A small servo motor drives wedge blocks to finely adjust the workbench curvature, counteracting minor deformations caused by slider and sheet stress. This ensures uniform bending angles across the entire length of long sheets, significantly reducing dimensional deviations in mass production and meeting high-end standards.Precision Sheet Metal FabricationTolerance requirements.

3. Intelligent CNC and Human-Machine Interaction System

The Zhenghao Youbang All-Electric Servo CNC Press Brake comes standard with an industrial-grade, press brake-specific CNC system. It supports 2D drawing import and direct DXF/DWG file loading to automatically generate complete bending process paths. The system also features 3D bending simulation for preview, helping prevent processing collisions in advance.

Standard Configuration: 4+1 axis联动 control. Multi-axis configurations can be upgraded as needed. The rear stopper uses a servo linear guide and ball screw drive for fast positioning response and stable displacement accuracy. The operation interface features a large touchscreen with clear, graphical logic. The equipment includes a built-in self-diagnosis module that real-time collects operational data such as servo current, motor temperature, screw load, and air pressure. Abnormal conditions are automatically logged with error codes for easy troubleshooting.

The chassis includes industrial data interface ports for seamless integration with MES and ERP production management systems. This enables the upload and retention of data on bending capacity, equipment utilization rates, and process parameters, supporting digital workshop and flexible production line deployment requirements while aligning withSmart Manufacturing EquipmentUpgrade direction.

IV. Operating Energy Consumption, Noise Reduction, and Maintenance Features

1. Energy-saving operation features

   The servo motor operates on a demand-based start-stop logic, delivering rated power only during the bending load phase. In no-load or standby states, it runs in low-power sleep mode, significantly reducing overall energy consumption compared to hydraulic press brakes of the same tonnage and aligning with green manufacturing and low-carbon production trends. With no risk of hydraulic oil temperature rise, the equipment avoids performance degradation caused by high heat, ensuring minimal accuracy fluctuation even under prolonged continuous processing conditions.

2. Low-noise cleanroom compatibility

   No risk of hydraulic fluid leaks, ensuring a clean workshop free from oil contamination. Operating noise levels are significantly lower than those of hydraulic press brakes, making this machine ideal for processing scenarios in medical devices, food equipment, precision electronics, and cleanroom environments where high hygiene standards are required.

3. Simple Operations Structure

   Eliminates high-wear hydraulic components such as valve manifolds, pumps, cylinders, seals, filters, and coolers. Drastically reduces maintenance tasks—no need for regular oil changes or leak inspections. Ball screws and linear guides feature automatic centralized lubrication systems that dispense precise amounts of grease on schedule, minimizing manual upkeep and significantly boosting overall equipment uptime.

5. Safety Protection and Durable Structural Design

The slider features a mechanical limit buffer structure with hard stops at the upper and lower travel limits. The entire machine is equipped with triple electrical safety protection: infrared light curtains, two-hand operation circuits, and emergency stop interlock switches. The servo system includes built-in overload current limiting; if sheet hardness exceeds specifications or load anomalies occur, it automatically reduces speed and shuts down to protect the lead screw, motor, and molds from impact damage.

The slider is forged as a single unit and paired with extended linear octagonal guide rails to ensure zero deviation or play throughout the entire stroke. Guide wear bushings are made of high-hardness alloy for superior wear resistance and long service life. All core transmission components undergo quenching and tempering heat treatment to achieve optimal hardness, ensuring reliable performance in continuous, high-volume daily bending operations.
