Plate rolling is a key process in metal manufacturing, with applications ranging from building large storage tanks and pressure vessels to manufacturing precision components for the aerospace and automotive industries. Plate rolling involves rolling and shaping flat metal sheets into round, conical or curved workpieces. This process is usually performed using a plate rolling machine.
Plate rolling machine is a general equipment for rolling metal sheets into cylindrical, arc-shaped or other shaped workpieces. This equipment is based on the principle of three points forming a circle, using the relative position changes and rotational motion of the workpiece to cause continuous plastic deformation of the plate, thereby obtaining a workpiece of a predetermined shape.
How to classify plate rolling machines according to the number of rollers
Plate rolling machines can be divided into three-roller plate rolling machines and four-roller plate rolling machines according to the number of rollers.
The three-roller plate rolling machine is fully hydraulically driven. The three rollers are all driving rollers. The upper roller only rotates but does not move. The two lower rollers rotate and can move in an arc at the same time.
Four-roller plate rolling machines differ from three-roller platerolling machines in that the machine has an additional lower roller, which enhances its ability to produce complex shapes. The rollers work in tandem to exert force on the metal plate, ensuring uniform rolling along the entire length.
Follow the four operating guidelines of the plate rolling machine
- Material Preparation: Before rolling, make sure the metal plate is clean and free of any debris or contaminants. Proper material preparation can prevent defects in the final product.
- Roller adjustment: Carefully adjust the position of the roller according to the desired rolling radius and angle. Take precise measurements to obtain the desired curvature.
- Feed Rate: Controls the feed rate of material into the machine to maintain an even roll along the entire length of the metal plate. Avoid overfeeding, which can cause the material to deform.
- Lubrication: Lubricate rollers and moving parts regularly to reduce friction and extend the service life of the machine. Use the manufacturer’s recommended lubricant for best performance.
Four major points of attention in the dry running test of the plate rolling machine
When the plate rolling machine is idling, it must comply with the following four technical specifications:
- When the plate rolling machine is performing an idling experiment, all movements are required to run smoothly and reliably without any errors.
- The electrical system, hydraulic system, gas system, lubrication system, cooling system and other devices of the plate rolling machine should be in normal and reliable operating condition.
- During the idling experiment of the plate rolling machine, the friction plates of the plate rolling machine must not be burned due to excessive friction.
- During the idling test of the plate rolling machine, excessive noise should not occur, and the noise sound pressure level of the plate rolling machine should comply with the regulations.
Conclusion
Plate rolling machines are indispensable tools in metal manufacturing, providing precision and efficiency in forming a variety of materials. However, operating these machines requires attention to detail to ensure quality performance and safety.
