Square SCR 4 Roll Plate Bending Machine Rolling Non - Ferrous Metal Profiles

Square SCR 4 Roll Plate Bending Machine Rolling Non - Ferrous Metal Profiles​

The Roll Plate Bending Machine is a kind of equipment for rolling carbon steel, stainless steel and non-ferrous metal profiles into a roll shape. The equipment is mainly composed of three parts: main engine, hydraulic station and electric control cabinet, so it is sometimes called hydraulic reeling machine. According to the process requirements of the reel, it can be divided into two-roll reeling machine, or three-roll reeling machine, etc.

4 Roll Plate Bending Machine Technical Parameters

Our advantage of 4 Roll Plate Bending Machine

Small 4 Roller Plate Sheet Metal Bending Rolling Machine with international advanced technology, controlled by PLC programmable numerically, all hydraulic driving, it's a heavy duty CNC rolling machine which can come true automatic bending, also it's the nesy equipment for bending multi section curved, square, round, conical and other special shape working piece.

Working principle and safe operation rules of four-roller bending machine
The upper roller of the CNC four-roller reeling machine acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder in the central symmetrical position of the two lower rollers. The final gear of the main reducer drives the two lower roller gears to engage in rotary motion for rolling. The plate provides torque. The flat plastic sheet of the equipment passes through the three work rolls (two lower rolls and one upper roll) of the equipment, and the metal plate is continuously bent in multiple passes by the downward pressing of the upper roll and the rotating motion of the lower roll. Permanent plastic deformation, roll into the desired cylinder, cone or part of it. The disadvantage of this hydraulic three-roll bending machine is that the end of the plate needs to be pre-bent by means of other equipment. The device is suitable for the thickness of the coil
For large-scale coiling machines of 50mm or more, a row of fixed idlers is added to the lower part of the two lower rolls to shorten the span of the two lower rolls, thereby improving the precision of the rolled workpiece and the overall performance of the machine.

1. The equipment must be managed by a dedicated person.
2. The operator must be familiar with the structural performance and usage of the equipment and only operate with the consent of the management personnel.
3. Check the safety device carefully before starting the machine.
4. When operating, it is strictly forbidden to place the hands and feet on the roller and transmission parts and the workpiece.
5. After the work is interrupted, the clutch should be hit to neutral.
6, multi-person collaborative work must be directed by someone.
7. It is strictly forbidden to work overload.
8. The dumping reset of the lifting roller of the upper roller and the balance of the upper roller shall be performed after the main drive is stopped.
9. It is forbidden to pile up workpieces and sundries in the workplace, so as to keep the machine and the site clean at all times.
10. After the operation is completed, the power should be cut off and the power box should be locked.

Introduction to four-roller bending machine
The machine is suitable for the bending forming work of sheet metal. It can roll round, curved and conical workpieces within a certain range, and has the function of pre-bending at the end of the plate. The remaining straight edges are small and the work efficiency is high. The metal sheet is roughly leveled on the machine.
CNC four-roll bending machine is made of square workpiece, conical workpiece, elliptical workpiece, CNC control, one-time forming, convenient and fast.
Four-roller bending machine is used for processing all kinds of metal plates (iron plate, aluminum plate, stainless steel plate), which can be rolled into a barrel shape, square barrel shape, oval shape, taper shape and other irregular shapes, and the maximum thickness can reach 10mm. The rolled parts are rounded and accurate. The equipment is operated with full digital control, reliable and high efficiency, and can be widely used in motorcycles, automobile manufacturing, electromechanical, solar energy and other fields.
