500-Ton Hydraulic Cold Drawing Machines: Heavy-Duty Precision for Large-Diameter Tubes and Bars

Subtitle: High-capacity hydraulic drawing technology delivers exceptional force control, dimensional accuracy, and surface quality for demanding heavy-wall tube and large-diameter bar applications.

The Power of 500-Ton Hydraulic Drawing

For manufacturers processing large-diameter tubes, heavy-wall sections, and high-strength alloys, a 500-ton hydraulic cold drawing machine represents the pinnacle of heavy-duty precision forming. This capacity level handles the most demanding reduction requirements while maintaining the smooth, controlled force essential for quality results.

Key Specifications

Why Hydraulic for High-Tonnage Applications?

• Smooth Force Application: Hydraulic systems deliver gradual, uniform pressure without mechanical impact—critical for maintaining surface integrity on heavy-wall tubes

• Exceptional Force Capacity: 500 tons provides the power needed for significant cross-sectional reduction in high-strength materials

• Precision Control: Servo-proportional valves and closed-loop feedback enable precise speed and force regulation

• Overload Protection: Hydraulic systems handle shock loads without damage, ensuring reliability in demanding operations

• Energy Efficiency: Variable-displacement pumps deliver power on demand, reducing energy consumption

Core Machine Features

• Heavy-Duty Construction: Massive, stress-relieved frame and extended-length carriage guidance ensure perfect axial alignment under full load

• High-Pressure Hydraulic System: Advanced axial piston pumps with servo-proportional valve control for smooth, programmable drawing cycles

• Precision Die Technology: Carbide or diamond-coated dies engineered for high-tonnage, high-wear applications

• Automated Material Handling: Heavy-duty feeding, pointing, and discharge systems for large-diameter tubes and bars

• Closed-Loop Process Control: Real-time monitoring of force, speed, and position with data logging for full traceability

• Operator Interface: Touchscreen HMI with recipe storage for different materials, sizes, and reduction schedules
