The electrical control cabinet of the bending machine, a critical component of the equipment, is responsible for power distribution and integration, signal processing, safety protection, and communication functions. Its performance directly affects the stability, safety, and intelligence level of the equipment. Shenglida Technology specializes in producing various types of bending machines, including fully automatic, CNC, semi-automatic, and fully automatic models. Additionally, the company offers high-quality molds and mandrels for bending machines. Below is an analysis of the electrical box compiled by the editor.
Typical box composition
| module | Key components | action |
| power-supply module | Switching power supply (such as Siemens SITOP), filter | Provides 24VDC/5VDC stable power supply with ripple <1% |
| Control the core | PLC (such as Mitsubishi FX5U), motion control card | Implement the bending algorithm and control the multi-axis linkage |
| driver element | Servo driver (Yaskawa Σ-7), frequency converter | Drive motor/hydraulic valve, dynamic response bandwidth is greater than or equal to 500Hz |
| human-computer interaction | HMI (Weilun MT8000), emergency stop button | Parameter setting, fault display |
| human-computer interaction | Safety relays (Pierz PNOZ), grating | Realize double circuit emergency stop and regional protection |
| communication interface | PROFINET, RS485 module | Connect with the upper computer /MES system |
Common faults and improvement measures
| fault phenomenon | Possible reasons | terms of settlement |
| The servo alarm is overloaded | Cable insulation damage / driver IGBT failure | Use flexible robot cables |
| PLC communication is interrupted | Grounding failure / switch failure | Install magnetic ring filter and use optical fiber communication |
| The electrical box is overheating | The cooling fan is blocked / the load rate is too high | Install heat exchanger |
| The solenoid valve is misoperated | Surge voltage shock | Increase the pressure sensitive resistor |
