The four-roller plate rolling machine is a mechanical equipment specially used for forming and bending metal sheets. This machine can pre-bend and roll various specifications of cylindrical and arc-shaped workpieces at one time. With the help of auxiliary devices, it can roll conical cylindrical parts.
The four-roller plate rolling machine has four rollers, the upper roller is the active roller, the lower roller and the side roller are the driven rollers, the upper roller is fixed, the lower and side rollers can be lifted and moved, the upper roller is driven by a hydraulic motor, and the rotation of the lower and side rollers is driven by the friction between the steel plate and the rollers. The lower roller and the side roller are pushed by the oil cylinders at both ends to achieve lifting and lowering movement. The turning and resetting of the bearing body on the front side of the upper roller are performed by the tipping oil cylinder, and the bearing bodies and oil cylinders of each roller are installed in the frames at the left and right ends. The left and right frames are the main body of the four-roller plate rolling machine, which adopts a welded structure and is installed on the integral base. The pusher device is to push the workpiece out of the machine after the workpiece is rolled and the tipping oil cylinder is flipped into place.
The four-roller plate rolling machine is easy to operate, with high rolling accuracy and good roundness. The pre-bending of the plate can be carried out on the four-roller plate rolling machine. It relies on the rise of the lower roller to press the end of the steel plate between the upper and lower rollers. Then the movement of the side roller is used to bend and deform the end of the steel plate to achieve the required style.
Six Application Features Of The 4-Roller Plate Rolling Machine
- Rolling can be completed after one-time loading, without turning around, and pre-bending on both sides;
- The three working rollers of the machine are all main drive rollers to prevent slipping during rolling, expanding the rolling range of the steel plate;
- The upper roller lifting and lower roller translation are hydraulically driven;
- Microcomputer control, automatic leveling, LCD display;
- The machine integrates mechanical, electrical and hydraulic, and each action is interlocked with each other;
- The system is equipped with overcurrent and overload safety protection.
Conclusion
The four-roller plate rolling machine can complete the pre-bending and curling of various specifications of cylindrical and arc-shaped workpieces after one loading, and the equipment performance is reliable.
When using the CNC four-roll plate rolling machine, you must keep in mind the key points of operation and be familiar with the operating procedures. Only by strictly following the requirements can you ensure that the production tasks are completed safely and efficiently.
