Recently, the independent innovation technology transformation project of the 80 X3500 mm three-roll bending machine of the Barge Heavy Industry has filled the domestic blank. This new technology has also obtained national patents.
The 80×3500mm three-roll bending machine is a large-scale bending equipment introduced by Shanghai Heavy Industry from Shanghai. However, the original design of the upper roller and the two lower rollers are fixed, and there is no conventional overturning mechanism. Although the entire cylindrical plate can be smoothly bent, after the processing is completed, the position of the upper roller cannot be changed and moved. As a result, the upper roller binds the cylinder plate therein, and the cylinder plate is restrained by the upper roller and cannot be taken out, which causes great inconvenience to the production.
How to smoothly remove the curved plate without losing the original equipment capacity is still blank in China. The engineers and technicians of Barge Heavy Industry decided to carry out the transformation and attack this technical difficulty in line with the idea of ​​“adhering to the introduction of technology and digestion and absorption and innovationâ€. After several years of hard work, such as argumentation-practice-re-discussion--practice, finally succeeded.
After improvement, on the basis of the original main part, the main transmission mechanism, the lower roller lifting mechanism, the lubrication equipment and the console, the drag-out mechanism, the support mechanism and the wedge-wedge wedge mechanism are added, and the bending and finishing of the equipment is completed. After the cylindrical plate, the upper roll is smoothly pulled out, and after the tube plate is taken out, the upper roll can be smoothly returned to the original position, and the whole process is stable, uniform speed, and no jamming phenomenon. Completely adapted and meet the processing requirements of new products. The modified 80×3500 mm three-roll bending machine has become the largest bending machine in the country. Specially designed to bend high-strength extra-thick steel plates into a cylindrical shape and a cone shape. The machine is not only suitable for bending the hull plate, but also for bending high-strength thick-walled containers and plates in large equipment such as metallurgy, petrochemical, power generation and cement.
