China 3 roll plate bending machine

In industrial production,bending metal sheets into the desired shape is a common processing requirement.The 3 roll plate bending machine has become an important equipment to meet this demand due to its simple structure,convenient operation,and high rolling accuracy.As a major manufacturing country,China's research and production technology of three roll plate rolling machines continues to advance.Understanding their working principles is of great significance for improving production efficiency and ensuring product quality.The following is the structural composition of China 3 roll plate bending machine.
The upper roller is one of the key components of a three roll plate rolling machine,usually located above the two lower rollers.It is generally made of high-strength alloy steel,with a larger diameter and good wear resistance.The upper roller can be moved up and down through a lifting device to adjust the gap between the upper and lower rollers,thereby controlling the bending radius of the sheet metal.
The China 3 roll plate bending machine has two lower rolls symmetrically arranged below the upper roll.The lower roller is also made of high-quality steel and has undergone special surface treatment to improve wear resistance and corrosion resistance.The lower roller is driven to rotate by a driving device,providing power for the rolling of the board.
The lifting device is mainly used to control the lifting motion of the upper roller.Common lifting devices include hydraulic cylinders,screw nut mechanisms,etc.The hydraulic cylinder lifting device has the advantages of smooth lifting and high load-bearing capacity,and can finely adjust the position of the upper roller to ensure the accuracy of rolling.
The driving device provides power for the rotation of the lower roller,usually consisting of a motor,reducer,etc.The motor transmits power to the lower roller through a reducer,causing the lower roller to rotate at a certain speed,thereby driving the sheet metal to move between the rollers and undergo bending deformation.
After the sheet metal is rolled into a cylindrical shape,there may be a certain degree of ellipticity or non roundness at both ends of the cylinder.To eliminate these defects,it is necessary to perform rounding operations.When straightening,place the cylinder on the lower roller,adjust the position of the upper roller to apply a certain pressure to the cylinder,and make the cylinder roll back and forth multiple times between the rollers.During the rolling process,the shape of the cylinder is gradually corrected,and the ellipticity and non roundness gradually decrease to meet the required roundness requirements.
The China 3 roll plate bending machine plays an important role in the field of metal sheet rolling through its unique structural composition and working principle.Understanding its working principle and key factors affecting the rolling effect can help operators use and maintain the equipment correctly,improve the quality and efficiency of rolling.Meanwhile,with the continuous development of technology,China 3 roll plate bending machine is moving towards intelligence,high precision,large-scale,and multifunctionality,which will provide stronger support for the development of the manufacturing industry.In the future,we look forward to greater breakthroughs in technological innovation and application expansion of China 3 roll plate bending machine,making greater contributions to promoting the high-quality development of China's manufacturing industry.
