The structural type of the marine three roll symmetrical plate rolling machine is a three roll symmetrical type. The upper roll performs vertical lifting and lowering motion at the symmetrical position of the center of the two lower rolls, which is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod and is hydraulic transmission; By using a specially designed reducer, the two lower rollers of the full rolling bearing are driven to rotate, providing torque for the rolled sheet metal; Multiple sets of rollers are installed at the lower part of the lower roller to improve its stiffness and allow for vertical adjustment; A rigid beam is installed at the upper part of the upper roller, and multiple sets of rollers are arranged between the beam and the upper roller to improve the stiffness of the upper roller; Suitable for rolling ultra wide arc-shaped parts.
Key technologies and innovative points of marine three roll symmetrical plate rolling machine:
Fully enclosed design to prevent dust from entering;
The marine three roll symmetrical plate rolling machine has changed the phenomenon of oil leakage everywhere in domestic three roll plate rolling machines, and the overall appearance has reached the level of foreign countries. Easy maintenance, high efficiency, long service life, and good environmental protection effect.
1. All steel welded structure with strong equipment rigidity, and optimized design calculation using computer finite element analysis method;
2. Both ends of the shaft roller are equipped with adjustable ball bearings;
3. The shaft rollers are precision machined from medium carbon steel after forging and tempering treatment;
4. The two lower rollers of the plate rolling machine have supporting rollers; Improve the accuracy of rolled workpieces and the overall performance of the machine.
5. Adopting centralized electrical control, the operation is simple and convenient;
6. The console adopts a humanized design, which is easy and convenient to operate; 7. Centralized lubrication system.
