Three rollers CNC Plate Rolling Machine to prevent deformation method

Three rollers CNC Plate Rolling Machine to prevent deformation method

If the three-roller plate rolling machine occurs barrel deformation, then it will lead to the plate rolling machine can not be used, once forced to use, then its potential danger will be very large. So in the face of this situation, you can prevent in advance by some methods, so as to avoid and reduce the possibility of barrel deformation of the rolling machine.

As we all know, the three-roller plate rolling machine to produce barrel deformation is mainly due to the lack of rigidity of the rollers and deformation, so that the same level of the plate reward rollers shaft length direction of the uneven force caused by the point. To roll the ideal barrel. Always keep the gap between the upper and lower rollers uniform, to ensure that its compression force and bending force on the plate is the same is very important. In order to solve this problem should take corresponding measures to prevent the deformation of the rolls or the deformation of the rolls to make up and eliminate. The following measures can be taken for specific situations.

1. The purchase of three rollers rollers to have sufficient rigidity, even in the polyurethane specification range of the plate material when the rollers are not deformed, but the rigidity of the rollers and its cross-sectional modulus, subject to the limitations of the equipment structure and other factors, so here it is recommended that the equipment manufacturers according to the length of the rollers and coil material properties, plate thickness and other different parameters to consider the rollers designed to be slightly curved, that is, to Rollers for household type correction.

2. The purchase of three-roller plate rolling machine under the middle part of the roll should be with auxiliary support roller to enhance the rigidity of the lower roll, the number of auxiliary support roller according to the length of the equipment set, or roller shaft arc correction and auxiliary support loam wheel both.

3. For tesco neither on the roller axis arc correction and not with the lower rollers auxiliary support rollers of the plate rolling machine, try not to roll the barrel in the equipment limit capacity, but should be simplified section rolled after the splicing. So that the rigidity of the rollers of the machine can withstand the compression force of the roll office and roll plate force without deformation.

4. In the case of not affecting the plate compression and rolling, appropriate to reduce the pressure of the upper roller, reduce the amount of pressure each time, but also reduce the deformation of the deflection of the rollers. Make the gap between the upper and lower rollers basically remain the same, so that it can reduce the amount of barrel deformation into the barrel.

5. Roll plate process in the plate material and the upper roller between the pad two lemon cavity pad block for auxiliary adjustment, in order to maintain the plate along the length of the roller axis direction by the compression force and bending force is basically the same.
Therefore, to prevent barrel deformation of the three-roller CNC rolling machine, you can prevent according to these five points above. Of course, in addition to do the above five points, but also in the daily manipulation of the use of plate rolling machine, pay attention to the mode of operation, because the wrong mode of operation will also affect the use of plate rolling machine state, so that it occurs to a certain extent of failure. So whether it is preventive measures, operation or maintenance work should be carried out correctly.

Automatic operation of CNC four-roller plate rolling machine

The upper roll and lower roll of the CNC four-roller plate rolling machine are active rollers, and the side roll is the driven roll, the upper roll position is fixed, and the lower and side roll can be lifted and moved, the upper and lower rolls are driven by hydraulic motors, and the side rolls are pushed by the oil cylinders at both ends to achieve lifting movement. The upper roller front side bearing body flip, reset by the overturning oil cylinder execution, each roller shaft bearing body and oil cylinder are installed in the left and right ends of the rack.

The left and right racks are the main body of CNC four-roller plate rolling machine with welded structure, CNC machine tool processing, installed on the overall base. The rewind device is rolled finished parts, and the tipping cylinder flips into place to push the workpiece out of the machine; all operations of the machine are carried out on the operating table.

1. The upper and lower rollers of CNC four-roller plate rolling machine can clamp the steel plate to prevent it from slipping off when bending.

2. Side rollers can play a positioning role, in the feed can make the steel plate to find the right. Convenient for bending conical pieces, oval pieces and shaped products.

3. CNC four-roller plate rolling machine pre-bending and rolling round, the steel plate can not turn around.
