**Detailed explanation of the working principle of electric plate rolling machine**
Electric plate rolling machine is a commonly used equipment in metal plate processing, mainly used for continuous rounding, leveling, bending and other processing of metal plates. The following is a detailed analysis of the working principle of the electric plate rolling machine, mainly from the aspects of drive and transmission, rolling deformation, flatness and bending, finished product coiling, control system, safety protection and auxiliary mechanisms.
1. * * Drive and Transmission**
The main power source of the electric rolling machine is the electric motor, which converts the high-speed rotation of the motor into low-speed and high torque output through a reducer. The output shaft of the reducer is connected to the main drive shaft, and power is transmitted to the working rollers through transmission methods such as chains, gears, or belts. The transmission system needs to ensure smooth power transmission and be able to withstand large working loads.
2. * * Roll deformation**
The electric plate rolling machine uses two working rollers, the upper and lower, to roll and deform the sheet metal. The rotation of the work roll and the feed of the sheet metal work together, causing plastic deformation of the sheet metal in the roll gap. The magnitude and distribution of deformation depend on factors such as the diameter, shape, gap of the working roller, as well as the material and thickness of the sheet metal. During the rolling process, the cross-sectional shape of the sheet metal will change, thereby achieving the process requirements of rounding and leveling.
3. * * Flatness and bending**
Flattening and bending are the two main functions of electric plate rolling machines. The smoothing function is mainly used to eliminate uneven defects such as waves and bumps generated during the processing of the board, making the surface of the board smoother. The bending function is to roll or bend the sheet according to the preset curvature. This function is achieved by adjusting parameters such as the gap between the work rolls, the feed rate and direction of the sheet metal.
4. * * Finished product coiling**
The processed board is rolled up by a winding mechanism for subsequent storage and transportation. The coiling mechanism usually includes coiling rollers, coiling motors, and tension control systems. The coiling roller is used to support and wind the sheet metal, the coiling motor provides the necessary power for coiling, and the tension control system is used to control the tension during the coiling process, preventing the sheet metal from loosening or deforming.
5. * * Control system**
The control system of the electric plate rolling machine is the core part of the entire equipment, used to control the operation and processing process of the equipment. The control system usually includes the main controller, operating panel, sensors, and actuators. The main controller adjusts parameters such as the gap of the work roller, the feed speed and direction of the sheet metal through the execution mechanism based on the operator’s instructions and sensor feedback information, to achieve preset processing requirements.
6. * * Security protection**
In order to ensure the safe operation of the electric rolling machine, the equipment is usually equipped with various safety protection devices. These devices include overload protection, emergency parking, protective covers, etc., which are used to promptly cut off power, stop equipment operation, or prevent personnel from coming into contact with hazardous areas in case of equipment failure or dangerous situations.
7. * * Auxiliary institutions**
The electric rolling machine is also equipped with various auxiliary mechanisms to improve the processing efficiency and convenience of use of the equipment. These auxiliary mechanisms include plate centering devices, plate clamping devices, lubrication systems, etc. The plate centering device is used to ensure that the plate is always at the center line position of the equipment during the processing, and the plate clamping device is used to fix the plate to prevent displacement or deformation during the processing. The lubrication system is used to provide lubrication for various components of the equipment, reducing wear and failure rates.
