The structural composition of the culvert thick corrugated plate rolling forming machine mainly includes the following core parts:
Feed mechanism
As the starting point of material input, it carries the thick steel plate to be processed through the feeding rack, and cooperates with the feeding roller and guide device to accurately feed the steel plate into the processing area at a constant speed. Some equipment is also equipped with an automatic feeding system, which can adjust the feeding speed according to the rolling rhythm to ensure smooth sheet transportation, avoid deviation or jamming, and lay the foundation for subsequent forming processes.
Rolling mechanism
This is the technical core of the device, consisting of multiple sets of customized rollers. The surface of the roller is processed with grooves of specific curvature and spacing according to the design requirements of the corrugated plate, and continuous plastic deformation force is applied to the steel plate through the pressure and rotation of the upper and lower roller groups. Rollers are usually made of high-strength alloy materials, which have both wear resistance and rigidity, and can meet the rolling needs of 2.5-6mm thick steel plates. In addition, the roller spacing and pressure of some equipment can be dynamically adjusted through hydraulic systems to adapt to the production of corrugated plates of different specifications.
Power and transmission system
Powered by an electric motor, the power is transmitted to the rolling mechanism and feeding mechanism through components such as reducers and couplings. The motor power varies depending on the equipment specifications, usually between 15-30kW, to ensure sufficient torque for roller rotation and steel plate conveying. Even when processing thick steel plates, it can maintain a stable speed to avoid forming defects caused by insufficient power.
control system
Adopting PLC (Programmable Logic Controller) combined with touch screen human-machine interface, real-time adjustment of feeding speed, rolling pressure, roller temperature and other parameters can be achieved. The operator controls the equipment to automatically complete the entire process of feeding, rolling, and forming through preset programs or manual input instructions. At the same time, the system has fault warning and data recording functions to improve production accuracy and safety.
Rack and support system
A frame structure welded from high-strength steel provides rigid support for each component. Shock absorbers are usually installed at the bottom of the rack to reduce vibration during the rolling process; The roller shaft seat is fixed to both sides of the frame with bolts to ensure uniform force during rolling and avoid affecting the dimensional accuracy of the corrugated plate due to frame deformation. The overall structure needs to be mechanically calculated to ensure stability during long-term high load operation.
