4-roller Plate Rolling Machine
1. 4-roller Plate Rolling Machine Summary
The device can pre-bend the ends of plate, feed steel plate just one time, and then to pre-bend the ends of plate, roll the workspace to drums shape, don’t need to return. The working up roller is the main drive roller, the down rollers and side roller use hydraulic drive to do elevate movement. And move controlled by computer, horizontal adjust automatic, show by screen, the synchromesh accuracy attached ±0.2mm. Turnover and resume of flip-bearing used hydraulic to drive. Installed balance system on the ends of up roller, so it’s easy to unload work piece. Adopt mobile independence operator table, so can operator at any time and any place, the machine has safety interlock device. For a world it has high technology, overall function, high accuracy and easy to operator. So it’s the model rolling machine, it’s the first choice in energy, transport, fossil oil, chemical, shipbuilding, steel and some other industries.
This machine composed of four working rollers, left and right rack of machine, base board, rolling rhombus tube function, turnover part, device part, sensor part, hydraulic system, electrical system and so on.
2. Mechanical Part of 4-roller Plate Rolling Machine
Working roller is the main part of device. The material choice steel 50Mn, and stand every standard very serious. These can ensure the comprehensive mechanical performance.
The base board and rock as the main parts of device, use wield structure. Do anneal treatment comply with arts standard; this can eliminate internal stress, so it has enough strength and steel performance. It can work on full load state.
Up roller is the main drive roller, the motor drive with the help of speed reducer. The output spindle of motor installed braking device, so it can ensure fixed position accuracy. All above these ensure the whole body has enough strength, the main joints connector with key and melt, so it’s easy to install and repair.
The down roller and side rollers do elevating movement drive by the ends oil vat. The ends bearings use axis adjustable roller bearings. Elevating synchronization controlled by computer. The turnover side of up roller installed turnover oil vat, the ends of up roller installed balance mechanism, so it’s easy to unload the work piece.
