The Yawei PBA series is positioned as a high-speed, universal CNC press brake. For fabrication customers looking to upgrade their bending operations, its primary strong points revolve around a balance of structural rigidity, advanced European hydraulics, and energy efficiency.
*High-Rigidity Frame: The machine frame is integrally welded from steel plate and stress-relieved in a large tempering furnace. It is machined in a single setup on a pentahedron machining center, guaranteeing that the frame resists deformation and maintains strict parallelism and verticality under heavy loads.
*Premium European Hydraulics: It features a fully closed-loop electro-hydraulic servo synchronization system imported from Germany (typically Rexroth or HAWE). This ensures highly stable, reliable oil pressure control with fast dynamic response times.
*Servo-Driven Main Motor: Instead of a traditional AC motor running continuously, the main motor uses a servo drive to power the oil pump. This setup slashes energy consumption by approximately 40%, significantly reduces operational noise, minimizes oil temperature spikes, and extends the lifespan of the hydraulic seals and oil.
*Automatic Mechanical Crowning: To prevent the "canoe effect" (where the center of a long bend is under-bent compared to the edges), the PBA features a mechanical deflection compensation device on the lower worktable. The CNC system automatically calculates and sets the compensation amount via closed-loop control, ensuring consistent angles across the full bending length.
*Independent Axis Control: The Y1 and Y2 cylinders are programmed separately. This allows the machine to work under eccentric loads or perform tapered bending when required.
*High-Precision Measurement: It utilizes Italian GIVI linear magnetic scales for position measurement, driving high ram repeat accuracy
*Fast Tool Changes: It comes standard with a mechanical fast-clamping system for the upper punches and a 2-V fast-clamping setup for the lower dies. This drastically cuts down setup times when switching between different profiles.
*Multi-Axis CNC Capability: Often equipped with a 4+1 axis configuration (Y1, Y2, X, R, and V crowning), driven by digital AC servo motors and ball screws with linear guides. This ensures the backgauge positions rapidly and accurately.
*Automation Ready: The PBA’s control architecture integrates seamlessly with robotic bending cells (like those paired with KUKA robots), making it highly scalable for customers looking to automate their production lines down the road.
亚威 (Yawei) PBA 系列定位为高速、通用型数控折弯机。对于希望升级折弯加工能力的钣金制造客户而言，其主要核心优势在于完美平衡了结构刚性、先进的欧洲液压系统以及卓越的能效表现。
* **高刚性机架：** 机架采用钢板整体焊接，并在大型回火炉中进行消除应力处理。通过五面体加工中心一次装夹加工成型，确保机架在重载下抗变形，并保持严格的平行度和垂直度。
* **优质欧洲液压系统：** 采用德国进口（通常为力士乐 Rexroth 或 哈威 HAWE）的全闭环电液伺服同步系统。这确保了油压控制的高度稳定和可靠，且具备极快的动态响应时间。
* **伺服驱动主电机：** 摒弃了持续运行的传统交流电机，主电机采用伺服驱动器来驱动油泵。这种配置可将能耗大幅降低约 **40%**，显著降低运行噪音，减少油温骤升，并延长液压密封件和液压油的使用寿命。
* **自动机械挠度补偿（Crowning）：** 为防止“独木舟效应”（即长工件折弯时中间角度大于两端），PBA 在下工作台上配备了机械挠度补偿装置。数控系统通过闭环控制自动计算并设定补偿量，确保整个折弯长度上的角度一致性。
* **独立轴控制：** Y1 和 Y2 油缸可独立编程。这使得机器能够在偏载（承受偏心载荷）情况下工作，或在需要时进行锥度（倾斜）折弯。
* **高精度测量：** 采用意大利 GIVI 直线磁栅尺进行位置测量，为滑块带来极高的重复定位精度。
* **快速换模系统：** 标配上模机械快速夹紧系统和下模双 V 型快速换模装置。在不同折弯型材之间切换时，可大幅缩短机器的调整和准备时间。
* **多轴数控能力：** 通常配备 4+1 轴配置（Y1、Y2、X、R 轴，以及 V 轴挠度补偿），由数字交流伺服电机驱动，并配有滚珠丝杠和直线导轨。这确保了后挡料装置能够快速且精确地定位。
* **支持自动化升级：** PBA 的控制架构可与机器人折弯单元（例如配备 KUKA 机器人的系统）无缝集成，使其具备极高的可扩展性，非常适合未来计划实现生产线自动化的客户。
