The main tools required for installing an electro-hydraulic servo CNC bending machine include lifting equipment, torque wrenches, hydraulic pressure gauges, levels, multimeters, sets of Allen wrenches, socket wrenches, pipeline cleaning equipment, and insulation resistance testers.
Lifting and Handling Tools
Forklifts or Cranes: Used to unload the machine from transport vehicles and move it to the installation location. Ensure lifting points are secure to prevent machine deformation.
Shims and Adjusting Blocks: Used for temporary support of the equipment and for leveling the foundation using a level.
Mechanical Installation Tools
Torque Wrenches: Used to tighten anchor bolts and critical connections, ensuring the manufacturer's specified torque value is met (e.g., Rexroth proportional valve installation requirements).
Sets of Allen Wrenches and Socket Wrenches: Used for disassembling and assembling standard fasteners such as cylinders, valve assemblies, guide rails, and lead screws.
Level (accuracy 0.02mm/m): Corrects the parallelism between the slider and the worktable, ensuring bending accuracy.
Hydraulic System Tools:
Hydraulic Pressure Gauge and Test Connector: Checks if the system pressure reaches the rated value (e.g., the pressure range corresponding to the nominal force of the 630KN model), and checks the working status of the relief valve and proportional valve.
Pipeline Cleaning Equipment (Acid Washing + Neutralization Device): Pre-treats the oil pipes to prevent impurities from entering the servo valve.
Fueling Cart and Filtering Device: Used to inject anti-wear hydraulic oil (ISO VG46 recommended) into the oil tank and filter impurities.
Electrical Testing Tools:
Multimeter and Insulation Resistance Tester: Tests the power supply voltage, phase sequence, and motor insulation resistance (should be >1MΩ) to ensure electrical safety.
Oscilloscope or Encoder Tester: Verifies the stability of the HEIDENHAIN grating ruler feedback signal, ensuring closed-loop control accuracy.
Laptop computer (with USB to serial cable): Used to connect to CNC systems (such as DELEM or ESA) to download parameters, set reference points, and debug programs.
