Description
The DW38CNC5A3S is a high-precision, fully automatic 5-axis CNC tube bending machine professionally designed for complex multi-radius tube bending processing. Featuring an innovative 3-layer integrated die structure and full servo 5-axis synchronous control system, this machine breaks the limitation of traditional single-die tube benders, enabling one-clamping multi-radius continuous bending. It is widely applied for high-efficiency and high-precision forming of round tubes in automotive, aerospace, HVAC, sanitary ware, furniture and mechanical equipment industries.
1. Core Structural & Nomenclature Advantages
The model code 5A3S represents the core configuration of the machine: 5A refers to five full servo synchronous axes (bending axis, feeding axis, tube rotating axis, clamping axis and auxiliary positioning axis) to realize fully automated, linkage and precise processing without manual intervention;3S stands for 3-layer composite bending die, which integrates three different bending radii on one die base.
Different from conventional single-die tube benders that require frequent die replacement for workpieces with multiple bending radii, the 3-layer die structure of DW38CNC5A3S supports seamless switching of three different radii in a single clamping cycle. It completely eliminates die replacement downtime, greatly reduces fixture adjustment costs, and effectively improves production continuity and processing efficiency for complex bent tube parts.
2. Superior Processing Performance & Precision
This machine is designed for medium and small-diameter precision tube bending, with a maximum processing tube outer diameter of Φ38mm. It is compatible with various metal materials including carbon steel, stainless steel, aluminum alloy, copper and alloy steel tubes, adapting to different wall thickness and bending process requirements.
Equipped with high-precision servo motors and imported encoder positioning system, the equipment achieves industry-leading processing accuracy: feeding and rotating positioning accuracy reaches ±0.05mm, and bending angle accuracy is controlled within ±0.1°. The minimum bending radius can reach 1.0 times the tube outer diameter (adjustable according to tube material and wall thickness), supporting tight-radius precision bending without tube wrinkling, deformation or collapse. Optional mandrel device is available for thin-wall tube bending to further guarantee tube forming quality.
3. Intelligent CNC Control System
The DW38CNC5A3S adopts a professional dedicated CNC tube bending control system with a humanized 10-inch touch screen operation interface, supporting multi-language switching to meet global customer operation needs. The system integrates powerful functional modules:
-
Supports XYZ and YBC dual-mode tube coordinate data import and editing, compatible with mainstream 3D design software data;
-
Built-in 3D bending simulation preview function, which can preview workpiece forming effect in advance to avoid processing errors and material waste;
-
Mass program storage function, which can store hundreds of bending programs for quick recall of mass production orders;
-
Multiple operation modes including manual, semi-automatic and fully automatic are optional, adapting to sample debugging, small-batch trial production and large-scale mass production;
-
Equipped with processing counting statistics and password protection functions to prevent unauthorized parameter modification and ensure production data security.
4. Stable & Durable Mechanical Design
The machine body adopts integral thickened steel plate welding and aging treatment process, with high rigidity, strong shock resistance and no long-term deformation, ensuring long-term stable high-precision operation. Key transmission parts such as linear guide rails and ball screws adopt high-precision wear-resistant accessories, with low friction and long service life. The hydraulic clamping system provides stable and uniform clamping force, effectively preventing tube displacement during high-speed bending and ensuring consistent product batch accuracy.
5. Comprehensive Safety & Humanized Configuration
To ensure operational safety and production standardization, the machine is equipped with a full set of safety protection devices: emergency stop button, safety light curtain, overload protection system, and abnormal operation sound-light alarm device. When equipment overload, parameter error or abnormal operation occurs, the system will automatically alarm and stop running to avoid equipment failure and personal injury. In addition, the machine is equipped with automatic lubrication system, which regularly lubricates key moving parts to reduce wear and extend equipment service life, lowering daily maintenance costs.
