The accuracy of electric servo bending machines is affected by multiple factors, which can be summarized and described in several main aspects:
I. Mechanical structure
1. **Transmission system**: The accuracy of the transmission system directly affects the rotation accuracy and reaction speed of the servo motor. The transmission system includes bearings, gears, connecting rods, etc. Their accuracy, wear degree and assembly quality will affect the accuracy of the bending machine.
2. **Frame and fuselage**: The rigidity and stability of the frame and fuselage determine the deformation of the bending machine when it is under load. The use of high-strength materials and reasonable design can reduce deformation and improve accuracy.
II. Control system
1. **Controller**: The accuracy of the controller determines the response accuracy of the bending machine to a given command. The processor speed, control algorithm and software design of the controller will affect the control accuracy of the servo motor.
2. **Servo motor**: As the actuator of the control system, the performance of the servo motor directly affects the motion accuracy of the bending machine. The torque, speed, positioning accuracy and response speed of the servo motor are all key factors.
3. Power supply
**Power supply stability**: The stability of the power supply has an important impact on the accuracy of the bending machine. Unstable power supply may cause unstable motor operation, increase noise, and affect control accuracy.
4. Encoder
**Encoder accuracy**: The encoder is the core part of the servo motor feedback system, which can provide information about the actual position and status of the motor. The resolution and accuracy of the encoder directly affect the control accuracy of the servo motor.
5. Materials and processes
1. **Processing materials**: The physical properties of different materials (such as elastic modulus, yield strength, etc.) will affect the deformation and rebound during the bending process, thereby affecting the processing accuracy.
2. **Process parameters**: Improper settings of process parameters such as bending force, bending speed and bending angle may also lead to a decrease in processing accuracy.
6. Operation and maintenance
1. **Operation skills**: The operator’s skill level and understanding of the machine will also affect the accuracy of the bending machine.
2. **Regular maintenance**: Regular maintenance and maintenance of the equipment can ensure that all components are in good condition, thereby maintaining high accuracy.
In summary, the accuracy of the electric servo bending machine is jointly affected by mechanical structure, control system, power supply, encoder, material and process, operation and maintenance, etc. In order to improve the accuracy of the bending machine, it is necessary to start from these aspects and make comprehensive considerations and optimizations.
