Technical details and manufacturing context for Servo Bending Unit

Definition
The Servo Bending Unit is a critical component of the Busbar Processing Module, responsible for accurately bending copper or aluminum busbars to specific angles required for electrical distribution systems. It integrates servo motor control with mechanical tooling to achieve precise, repeatable bends while maintaining material integrity and electrical conductivity.
Working Principle
The unit receives position commands from the system controller, which drives servo motors to rotate bending tools around a fixed axis. The busbar is clamped in position while the bending arm applies controlled force at predetermined points, creating precise angular deformations. Servo feedback ensures accurate positioning and force control throughout the bending cycle.
Common Materials
High-strength steel, Copper busbar, Aluminum busbar
Technical Parameters
  • Bending accuracy tolerance (mm) Per Request
Components / BOM
  • Servo Motor
    Provides precise rotational control for bending operations
    Material: Steel housing with copper windings
  • Bending Arm
    Applies controlled force to deform the busbar
    Material: Hardened tool steel
  • Clamping Mechanism
    Secures busbar in position during bending
    Material: Hardened steel
  • Position Sensor
    Monitors bending angle and provides feedback to control system
    Material: Stainless steel with electronic components
Engineering Reasoning
0.5-2.5 N·m torque, 0.01-0.5 mm positioning accuracy, 0-180° bending angle
Exceeding 3.0 N·m torque causes permanent gear deformation, exceeding 0.6 mm positioning error causes dimensional non-conformance, exceeding 200° bending angle causes material fracture
Design Rationale: Plastic deformation of hardened steel gears due to Hertzian contact stress exceeding 1500 MPa yield strength, cumulative positioning error from servo encoder quantization (12-bit resolution), material fracture at bending radii below 2× busbar thickness violating minimum bend radius rule
Risk Mitigation (FMEA)
Trigger Servo motor encoder signal loss due to electromagnetic interference from adjacent 400V AC power lines
Mode: Uncontrolled angular overshoot exceeding ±5° tolerance causing busbar deformation beyond 180° limit
Strategy: Shielded twisted-pair encoder cables with ferrite cores, physical separation of 300 mm minimum from power conduits, differential signal transmission
Trigger Lubricant degradation in reduction gearbox due to copper particulate contamination from busbar abrasion
Mode: Gear tooth pitting and increased backlash exceeding 0.1 mm causing positional repeatability error of ±0.3 mm
Strategy: Magnetic filtration system with 10 μm particle capture, synthetic polyalphaolefin lubricant with anti-wear additives, quarterly oil analysis monitoring for copper >50 ppm
