Our new 4 roller bending machine has many advantages. It is the easiest to use a hydraulic plate bending machine, because it can clamp the plate between two electric center rollers, pre-bend at the end, and bend in one direction and through the whole body at a time. Due to the continuous squeezing of the center roller, The sheet remains square without slipping during the pre-bending and bending cycles. This makes ezhong 4 roller 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.

1. The 4 roller 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 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 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 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 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 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 bending machine adopts high strength and high life solid bearing roller with long time and small deformation.
The roller adopts high strength and high life solid bearing roller with long time and small deformation.
The whole 4 roller bending machine adopts integral steel plate welding, thick and beautiful, the stability is good.
Simple operation, single person can work independently.
The 4 roller bending machine is widely used in petroleum, chemical, boiler, shipbuilding, utilities, metal structures and machinery manufacturing industries. The sheet metal forming machine is can rapid prototyping, high-precision coil, without auxiliary equipment, less investment.
