Detailed Manufacturing Process Flow of a Hydraulic Bending Machine

The production of a high-quality hydraulic bending machine for sale is a multi-stage process, meticulously designed to ensure durability, precision, and long-term performance. It combines advanced engineering with stringent quality control.

1. Material Selection and Preparation:

   High-grade structural steel (e.g., Q235, Q345, or equivalents like ASTM A36, S355JR) is chosen for the main frame and stress-bearing components due to its excellent strength-to-weight ratio and weldability. Hydraulic components utilize specialized alloys for cylinders, pumps, and valves, ensuring high pressure resistance and minimal wear. Critical components such as dies and punches are typically made from hardened tool steel (e.g., Cr12MoV, 42CrMo), offering superior wear resistance and toughness. Incoming materials undergo chemical composition analysis and mechanical property testing to ensure compliance with standards.

2. Frame Fabrication (Casting/Welding):

   Large-tonnage machine frames may involve casting of high-strength nodular cast iron for superior vibration damping. More commonly, for precision press brakes, the frame is fabricated through high-precision welding of pre-cut and machined steel plates. Advanced welding techniques, such as submerged arc welding or robotic MIG/MAG welding, are employed to ensure robust, uniform welds. Post-welding, stress relief annealing is performed to eliminate residual stresses, preventing deformation and ensuring structural integrity over the machine's estimated 15-20 year service life.

3. Precision Machining (CNC):

   Major components like the machine bed, upper beam, back gauge, and cylinder bores undergo meticulous CNC machining. This includes milling, boring, and grinding to achieve precise geometric tolerances (e.g., parallelism within 0.02 mm over 3 meters). High-precision machining ensures optimal alignment of moving parts, reducing friction and maximizing bending accuracy. Honing processes are applied to hydraulic cylinder bores to achieve micro-level surface finishes, critical for seal longevity and smooth piston movement.

4. Hydraulic System Assembly:

   This involves the integration of high-pressure pumps (e.g., Bosch Rexroth, Vickers), control valves (e.g., Hoerbiger, Atos), hydraulic cylinders, and a precision-engineered manifold. All hydraulic lines are meticulously cleaned, flushed, and pressure-tested before assembly to prevent contamination. The system is designed for optimal fluid dynamics, minimizing pressure drops and maximizing response times.

5. Electrical and Control System Integration:

   Advanced CNC control systems (e.g., Delem, Cybelec, ESA) are integrated, offering intuitive programming, automatic angle correction, and multi-axis control. High-quality electrical components, including motors, sensors, and wiring, are sourced from reputable suppliers (e.g., Siemens, Schneider, Omron). Comprehensive wiring and grounding are implemented to ensure safety and prevent electromagnetic interference.

6. Assembly and Alignment:

   Components are assembled with precision, focusing on the parallelism of the upper and lower beams, and the accuracy of the back gauge system. Laser alignment tools are used to ensure minute deviations are corrected. Tools like punches and dies are installed and calibrated.

7. Testing and Quality Control:

   Each machine undergoes rigorous testing, adhering to international standards such as ISO 9001 for quality management and relevant ANSI/CE directives for safety and performance. This includes:

   • Hydraulic Pressure Test: To verify leak integrity and component strength under maximum operating pressure (e.g., 125% of nominal pressure).
   • Functional Test: To confirm all machine movements, control functions, and safety interlocks operate correctly.
   • Geometric Accuracy Test: Measuring parallelism, straightness, and perpendicularity of critical surfaces, often using laser interferometers, to ensure bending precision.
   • Bending Performance Test: Real-world bending of various material thicknesses and types to validate angle accuracy, repeatability (typically within ±0.01 mm for position, ±0.5 degrees for angle), and tonnage consistency.
   • Noise and Vibration Analysis: To ensure compliance with occupational health and safety standards.
8. Surface Treatment and Finishing:

   Components undergo cleaning, sandblasting, priming, and multi-layer epoxy painting for corrosion resistance, ensuring durability even in harsh industrial environments like petrochemical facilities. This also enhances the machine's aesthetic appeal and extends its protective life.

Technical Specifications and Parameters
