PLC Control 4 Roll Plate Bending Machine Cnc Plate Rolling Machine 80-500mm
four Roll Plate Bending Machine description:
The four roll bending machine is a metal plate bending and correcting machine, which is used for forming and bending of sheet metal. The pre bending and curling forming of all kinds of cylindrical and arc parts can be completed after loading once, and the rough shaping of sheet metal can also be done. It is widely used in shipbuilding, boilers, aviation, bridges, hydropower, chemical industry, metal structure and machinery manufacturing industries.

4 Roll Plate Bending Machine is mainly used for the rolling of square cylinder, elliptical cylinder, triangular cylinder and circular cylinder.
The 4 Roll Plate Bending Machine is a servo CNC plate rolling machine, which is composed of four rollers: up, down, left and right. The upper and lower rollers rotate and the upper and lower rollers are controlled by servo motor. The up and down movement of the left and right rollers determines the diameter of the workpiece.The Rolling of workpiece is completed by four-axis linkage .
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.
Features of 4 Roll Plate Bending Machine
The Machine designed based on Germany Technology.
Pre-bending, rolling and round calibration can be completed in one pass (without turn the plate back).
Easy to operate, diversification rolling available.
Very little fault in roller movement.
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.
