EZHONG hydraulic 4 roll plate bending machine is the easiest hydraulic plate bending machine. It does not need to pre-bend both ends of the sheet and then roll it like a 3 roll bending machine. Feed the sheet.
Due to the ability to clamp the plate between two electric central rollers, pre-bend at the end, and bend through the entire body in one direction and at a time. Due to the continuous squeezing of the central roller, the plate remains square during the pre-bending and bending cycle. Will not slide. This makes our 4 roller plate bending machine very suitable for being controlled by NC or CNC, and single-person operation, simple and efficient. Completely European design, streamlined appearance, the rollers, materials and bearings used in the production are all European quality, which is widely praised by customers at home and abroad.
- EZHONG 4 roller plate bending machine is very suitable for medium plate or aluminum plate and stainless steel plate.
- The whole cylinder or parts of different radii can be rolled easily.
- Both pinch roll and side roll are driven by the hydraulic piston.
- Overload protection.
- Three groups of digital output to display the position of work roll.
- The hydraulic inverted head frame is convenient for the unloading of the rolled cylinder.
- Independent mobile console for easy operation.
- Welding steel frame and overall stress relief.
- All work rolls are forged with high-quality steel, heat-treated and induction hardened.
- Coiling cone device of coiler.
- Hydraulic balance system.
- Two-speed working system.
- This roll plate bending machine is manufactured according to EC safety standards and CE certification.
- All electrical and hydraulic components are of famous brands.
1. The 4 roller plate bending machine operates the lower roller to rise to make the busbar slightly larger than the working thickness under the upper roller, and then operates the feeding side roller to make the upper busbar on the same level, and then operate the other side between the upper and lower rollers. Time rises.
2. 4 roller plate bending machine feeding: feed the steel plate horizontally so that the end of the steel plate is in contact with the entire front roller, and then the front roller is lowered to the original position.
3. The 4 roller plate bending machine tightens the steel plate and pre-bends the end: According to the thickness and material of the steel plate, the pressure of the lower roller circuit is adjusted within a specific range, the lower roller is operated to lift and clamp the steel plate, and the upper roller is started to rotate. When following the bending position, stop the rotation of the upper roller. At this time, the left end of the centerline of the upper and lower rollers should have the necessary clamping length equivalent to 1.5 times the plate thickness. Then, the rear roller is lifted to pre-bend the end of the steel plate.
4. The 4 roller plate bending machine uses the front roll to pre-bend the other end of the steel plate. After pre-bending the left end, lower the rear roller to its original position and start the upper roller. When the steel plate follows the above-mentioned bending position, the upper roller stops rotating. Before the operation, the roller lifts the other end of the pre-bent steel plate and then adjusts the pressure of the two roller circuits left and right.
5. 4 roller plate bending machine pre-bending: adjust the front and rear rolls to the corresponding positions required for the work, and start the upper roll for forming and bending.
6. 4 roller plate bending machine forming and bending: Take out the workpiece: After the bending is completed, lower the bottom roller to a lower position, and then lower the workpiece to a certain position with the rollers on both sides, flip it over, and lift the workpiece parallel to the top roller, Take out the workpiece, complete a work cycle.
The 4 roll plate roller adopts high-strength and long-life solid bearing roller with long service life and small deformation.
The transmission gear is made of forged high-carbon steel with high hardness and strong wear resistance. No friction, anti-rust, permanent lubrication-free.
The whole 4 roller plate bending machine adopts integral steel plate welding, which is thick and beautiful, and has good stability.
Operation-friendly CNC control automation mode for rolling, or a more powerful and advanced CNC system, which can be automatically programmed to reduce the dependence on experienced operators. The operation is simple, and a single person can work independently.
The 4 roller plate bending machine is widely used in petroleum, chemical, boiler, shipbuilding, utilities, metal structures and machinery manufacturing industries. The 4 roller plate bending machine can rapid prototyping, high-precision coil, without auxiliary equipment, less investment.
