China 3-roll bending machine

The 3-roll plate rolling machine achieves continuous bending and forming of materials such as steel plates and stainless steel plates through the vertical lifting of the upper roll and the rotational motion of the two lower rolls.It is widely used in industries such as shipbuilding,pressure vessels,steel structures,and wind power towers.In recent years,China's 3-roll bending machines have made breakthroughs in technological iteration,material application,and intelligent control,gradually transitioning from"mid to low-end manufacturing"to"intelligent manufacturing".
The characteristics of China's 3-roll bending machine mainly include the following aspects:
1.Structural type:The 3-roll bending machine is mainly divided into two types:symmetrical and asymmetrical.The upper roller of the symmetrical 3-roll bending machine moves vertically at the symmetrical position in the middle of the lower roller,driven by a screw and worm.The lower roller is driven,and the output gear of the reducer meshes with the lower roller gear to provide torque for the rolling plate.The upper roller of the asymmetric 3-roll bending machine is the main drive,and the lower roller moves vertically up and down,and meshes with the upper roller gear through the lower roller gear as the main drive;The edge roller performs tilting and lifting motion,with dual functions of pre bending and coiling.
2‌.Performance characteristics:It has dual functions of pre bending and curling.In addition,the 3-roll bending machine is suitable for bending deformation of metal sheets and can roll circular,curved,and conical workpieces.It is widely used in industries such as shipbuilding,boilers,aviation,hydropower,chemical engineering,metal structures,and mechanical manufacturing.
3.Working principle:The 3-roll bending machine uses the downward pressure of the upper roll and the rotational motion of the lower roll to continuously bend the metal plate between the three working rolls,producing plastic deformation and rolling it into the desired cylinder,cone or part thereof.The transmission system of the hydraulic three roll bending machine drives the transmission shaft through a motor,which drives the gears of each roll to mesh and achieve the function of rolling the plate.
4.Application areas:3-roll bending machines are widely used in various industries such as mechanical manufacturing,automobiles,electrical appliances,ships,containers,instruments,etc.,especially in mass production where they can maintain angular consistency.In addition,the asymmetric 3-roll bending machine is suitable for rolling ultra long cans of various cross-sections,improving the flatness of the product and the accuracy of the rolled workpiece.
China's 3-roll bending machine has formed a complete product matrix covering"economic intelligent"through technological self-reliance,intelligent control,and industrial customization.Its core advantages are reflected in:large tonnage and high-precision support for heavy equipment manufacturing capabilities,CNC and detection technology to improve molding quality stability,optimization of full lifecycle costs to enhance market competitiveness,green design and industry adaptation to promote sustainable development.
