The four-roller plate rolling machine is suitable for bending and forming of metal sheets. It can roll round, arc-shaped and tapered workpieces within a certain range. It also has the function of pre-bending the end of the sheet, with small remaining straight edges, high work efficiency, and Metal sheets can be roughly leveled on this machine. • This machine is suitable for bending and forming of metal sheets. It can roll round, arc-shaped and tapered workpieces within a certain range. It also has the function of pre-bending the end of the sheet. The remaining straight edge is small, the work efficiency is high, and it can The metal sheet is roughly leveled on the machine. • The lifting and turning of the upper roller, the tilting reset of the bearing and the balancing of the upper roller must be carried out after the main drive is shut down.
W12 series four-roller plate rolling machines have a mechanically powered upper roller and pneumatic-powered lower roller and side ro;;er and are opearated by centralized electric control. Itcan complete the pre-deformation of both ends of the plate and the rolling of drum and arch type woekpiieces by only one feeding. It is capable of certain shaping and leveling and also of direct pre-bending which is both work saving and material saving.
The plate bending machine is a piece of equipment that uses work rolls to bend and shape sheet metal. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate bending machine is to move the work roller through the action of external forces such as hydraulic force and mechanical force, thereby bending or bending the plate into shape. According to the rotational movement and position changes of work rolls of different shapes, parts such as oval parts, arc-shaped parts, and cylindrical parts can be processed.
The position of the upper roller is fixed, and the lower roller moves upward in a straight line to clamp the steel plate. The rollers on both sides move closer to the upward roller in a straight line or arc to adjust the curvature radius of the drum. The roller motion forms of four-roller and three-roller plate rolling machines are different, but the working principle is the same. They both use the principle of three-point circle determination to roll different radii. However, the pre-bent straight edges and rounded roundness of the four-roller plate rolling machine are better than those of the three-roller.
