          Nantong Mingtai introduces the key points of knowledge that should be mastered by the purchase of four-roller bending machine


          Plate rolling machine is a kind of common forging machine equipment that can bend and roll nonmetallic sheet metal into cone, spherical body, cylinder or other shapes. This performance is widely used in manufacturing, boiler steam, chemical industry, nonmetallic structure and machine building. Four-roller plate rolling machine is suitable for sheet metal bending forming work, can roll round, arc and conical workpiece within a certain range, and sheet metal end pre-bending function, the remaining straight edge is small, high efficiency, and can be used on the machine for rough leveling of sheet metal.

          Four-roll rolling machine and three-roll rolling machine roller motion form is different, but the working principle is the same, but also use the principle of three-point circle to carry out different radius rolling. The position of the upper roller is fixed, and the lower roller moves upward in a straight line to clamp the steel plate. The curvature radius of the drum can be adjusted by moving the roller up in a straight line or arc.

          Any machine should operate correctly in accordance with the requirements of the process. Let's talk about the correct operation points of the four-roller bending machine.

          (1) The plate rolling machine must be managed by special personnel.

          (2) the operator must be familiar with the structure performance and use of the winding machine, after the responsible management personnel agree, can be operated.

          (3) Carefully check whether the safety device is in good condition before starting.

          (4) During operation, hands and feet are strictly prohibited to be placed on rollers and transmission parts and workpieces.

          (5) After work interruption, the clutch should be hit to neutral.

          (6) There must be a special person to direct multi-person cooperative operations.

          (7) Overload is strictly prohibited.

          (8) The lifting and reversing of the upper roll, the dumping and reset of the bearing and the balance of the upper roll shall be carried out after the main drive stops.

          (9) It is forbidden to pile up workpieces and sundries in the work site, and keep the machine tools and the site clean at all times.

          (10) After the operation, cut off the power supply and lock the power box.

          Four-roller plate rolling machine is an important equipment in the production of enterprises, during the use must be in accordance with the correct way of operation.
