CNC Hydraulic 4-Roll Plate Bending Machine 2500mm Width 630kN Pressure
- Targeted Adaptability for Stainless Steel:Specialized for stainless steel plate processing (common thickness 3-30mm), compatible with 304, 316, 430 and other stainless steel grades. The roll surface adopts anti-scratch treatment to avoid damaging the stainless steel’s smooth surface, solving the problem of surface scratches during traditional bending and ensuring the aesthetic and corrosion resistance of finished products.
- 4-Roll Hydraulic Stability:4-roll structure realizes multi-directional force application, with hydraulic-driven roll synchronization adjustment. It can complete arc forming, edge pre-bending and full-circle rolling in one operation, avoiding secondary processing. Compared with 3-roll machines, it reduces stainless steel plate deformation by 40% and improves forming accuracy to ±0.2°.
- Efficient & Safe Operation:Equipped with high-pressure hydraulic system, the maximum bending force reaches 100-500T, suitable for heavy-duty stainless steel processing; with emergency stop button and pressure overload protection, it automatically shuts down when abnormal. The touchscreen operation interface supports parameter storage, and the average processing efficiency is 20% higher than similar products.
- Wide Industrial Application:Ideal for stainless steel product manufacturing, such as food machinery (stainless steel tanks), medical equipment (sterilization containers), chemical pipelines, and decorative stainless steel components, meeting high-standard forming needs of stainless steel in multiple industries.
- The company's automatic bending machine adopts advanced robot technology and numerical control system, which supports automatic feeding, 3D visual inspection, automatic positioning, bending Angle adjustment and automatic unloading, etc., to realize the automatic production of the whole process. It is equipped with an ACB laser Angle detection system to ensure bending accuracy and repeatability of up to 5 microns.
- The device supports a variety of bending methods, such as hanging bending, mold bending, etc., and optimizes energy consumption through on-demand servo drive. In addition, the bending machine can be integrated with the central control system, ERP and MES systems to achieve intelligent data interaction and production management.
- Wide applicability applicable to a variety of metal materials and complex workpiece bending, widely used in automobile manufacturing, machining, home appliance manufacturing and other industries
