The purpose of the three-roller plate bending machine is a shaping machine for continuous point bending of plates. It has the function of rolling O-shaped, U-shaped, multi-segment R, and other shapes of plates. At present, the three-roller bending machine plays a huge role in modern industry.

What are the characteristics of the mechanical three-roller plate bending machine?

Performance characteristics of mechanical three-roller plate bending machine: The structure of the machine is three-roller symmetrical. The upper roller moves vertically at the central symmetrical position of the two lower rollers. It is obtained by the transmission of the screw and screw nut and the two lower rollers. Rotational motion, through the output gear of the reducer meshing with the lower roller gear, provides torque for the rolled plate. The disadvantage of three-roller plate bending machine is that the end of the plate needs to be pre-bent with the help of other equipment.

 

What are the characteristics of the hydraulic three-roller plate bending machine?

The main features of the hydraulic three-roller plate bending machine: the upper roller of the machine can be vertically raised and lowered, and the vertical lifting hydraulic transmission is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven in rotation, and the output gear of the reducer has meshed. Provide torque for the coil, and there is a supporting roller under the lower roller, which can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long cans.

 

How to make a conical tube with an ordinary three-roller plate bending machine?

There are two ways to make a tapered pipe with an ordinary three-roller plate bending machine:

1. Install cone-bending device. If the diameter of the small head is too small, you can consider adding a built-in cone reeling device.

2. If the diameter is small, the board is thin, and the reel is long, the three rollers can be made into a conical roller, but the required radian should be calculated. The roller has a certain inclination, and the lateral force is very large during rolling, so it is necessary to add a lateral reduction gear wheel, and the gear wheel needs to be quenched.

The upper roller of the plate bending machine is at the symmetrical position of the two lower rollers through the hydraulic oil in the hydraulic cylinder to act on the piston to make a vertical lifting movement. The final gear of the main reducer drives the gears of the two lower rollers to mesh and rotate to provide torque for the rolled plate. The flat plastic metal plate of the bending machine passes between the three work rolls (two lower rolls and one upper roll) of the bending machine, with the help of the lower pressure of the upper roll and the rotation of the lower roll.

The metal plate is continuously bent through multiple passes to produce permanent plastic deformation and rolled into the required cylinder, cone, or part of them. The disadvantage of this hydraulic three-roller bending machine is that the end of the plate needs to be pre-bent with other equipment. This rolling machine is suitable for large rolling machines with a thickness of more than 50mm. A row of fixed idlers is added under the two lower rollers to shorten the span of the two lower rollers, thereby improving the precision of the rolled workpiece and the overall performance of the machine.

 

The three-roller plate bending machine greatly improves the efficiency of industrial production and is widely welcomed in the global market. ChaoLi Company has committed to providing the most suitable 3 roll plate bending machine at a reasonable price, and whatever it takes to satisfy the customer’s needs.
