在钣金加工装备智能化、绿色化转型的大环境下，All-Electric Servo CNC Press BrakeWith its hydraulic-free, low-energy-consumption, and high-precision structural design, it has become the leading forming equipment for precision sheet metal and clean production environments. Shanghai Zhenghao Youbang Heavy Industry Machinery Co., Ltd. has long specialized in the R&D and manufacturing of metal forming equipment, while simultaneously expanding its strategic layout.电液伺服数控折弯机、纯电伺服数控折弯机、卷板机、冲压设备Multiple product lines leverage our proprietary motion control algorithms and precision structural craftsmanship to deliver stable, reliable all-electric servo bending solutions tailored for high-precision sheet metal bending across diverse industries.

一、整机驱动架构：永磁伺服直驱，摒弃液压传动体系

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 adopts双永磁同步伺服电机搭配高精度滚珠丝杠直驱滑块的机械传动结构，全程无液压油、无泵站组件，从底层改变动力传递形式。

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.全电折弯机区别于液压机型的核心技术标志。

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.精密折弯机Basic rigid process assurance.

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

设备搭载高精度磁栅尺全域位置采集组件，实时采集滑块左右两侧行程位置数据，信号实时回传数控主机，构成 “数控系统 — 伺服驱动器 — 磁栅尺” 三重闭环调控体系。

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.

工作台集成机械式挠度补偿模组，依靠小型伺服电机驱动楔块微调工作台弧度，抵消滑块与板材受力产生的微量形变，长幅板材折弯全长角度均匀，大幅降低批量工件尺寸偏差，满足高端精密钣金加工Tolerance 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.

机身预留工业数据对接端口，可匹配 MES、ERP 生产管理系统，实现折弯产能、设备稼动率、工艺参数的数据上传留存，适配数字化车间、柔性生产线搭建需求，契合智能制造装备Upgrade direction.

四、运行能耗、降噪与运维特性

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. 低噪洁净工况适配

   整机无液压渗漏风险，车间环境无油污污染，运行机械噪音数值远低于液压折弯设备，适合医疗器械、食品设备、精密电子、无尘车间等对生产环境洁净度有要求的加工场景。

3. Simple Operations Structure

   去除液压阀组、油泵、油缸、密封件、液压滤芯、冷却器等大量易损耗液压配件，日常维护项目大幅缩减，无需定期更换液压油、检修油路渗漏。丝杠、导轨配备自动集中润滑装置，定时定量加注润滑脂，减少人工养护频次，设备整体稼动时长有效提升。

五、安全防护与结构耐用设计

滑块配备机械限位缓冲结构，行程上下极限设置硬限位防护；整机标配红外安全光栅、双手操作回路、急停联锁开关三重电气安全防护；伺服系统内置过载限流保护，板材硬度超标、负载异常时自动降速停机，保护丝杠、电机、模具不受冲击损伤。

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.
