Rolling Machine Four-Roller Structure Three-Roller Cold Rolled Sheets---Product Description:
01Rolling Machine
The AUTO rolling machine is one of the important parts of the LNG production line.
The rolling machine adopts the four-roller structure with the upper roller as the main drive.
Its working principle is a combination of hydraulic and CNC rolling of sheet metal.
02Rolling machine Working principle
03Rolling Machine Four-Roller Structure Three-Roller Cold Rolled Sheets---Introduction to the work of the rolling machine
The machine adopts the four-roller structure with the upper roller as the main drive.
The equipment has the function of pre-bending the end of the plate. The metal sheet can be loaded at one time, and the plate end pre-bending and the roll forming of the workpiece can be completed without turning.
The upper working roller of this machine is the main driving roller. The lower roller and both sides of the roller adopt hydraulic transmission. The lifting displacement is controlled by the computer, automatic leveling, screen display, and the tilting and resetting of the turning bearing body to adopt hydraulic transmission. The tail of the upper roller Equipped with a balance mechanism to facilitate the unloading of the rolled workpiece and cylinder. Equipped with a mobile independent operating table, which can be moved and operated at any time, and the machine is equipped with a safety interlock device. The machine has a high technical level, complete functions, high precision, and easy operation. It is the most ideal model for rolling round, arc, and conical workpieces in industries such as energy, transportation, petroleum, chemical industry, boilers, shipbuilding, hydropower, and metal structures.

Roller guidance "Planetary guidance" (no friction, anti-oxidation, minimal lubrication), hydraulic pressure, overload protection system, unique patented design |
| The movement of the roller is hydraulic, through the large-diameter hydraulic cylinder with a chrome-plated layer |
| The clamping pressure of the plate can be preset by the operator on the control panel according to the thickness of the plate. When working, it can be automatically selecte by CNC and the pressure change can be monitored by CNC in real time. |
| CNC |
The numerical control displays the position of the side rollers and memorizes them. Press the "Start" button through the keyboard, and the specific side rollers will automatically return to the previous memory position. (Different materials change the diameter and manually correct them to improve the result). With semi-automatic CNC, the operator must "start" each additional memory movement and move all the memory movements through the joystick. The rotation of the roller must always be manually triggered by the joystick. |
| The numerical control determination can be used in manual mode, with higher accuracy than any manually controlled machine. |
The products shown above are only the details of some models and products in this machine. We sell all the equipment in the solar water heater production line. If you are interested, we look forward to your inquiry.
Feature
It is made by steels of high quality and certain processing technique, and is characterized by compact structure, reliable drive and uniform radius of curvature.
It has roller set to adjust bracket component according to the length of work piece's need, they are taken out from the end of the machine. This machine not only works fast, but can ensure the roller will not bend during the work and the bus bar is straight, and cylindricity is good after shaping up.
It employs the principle of electric motor spiral to drive the lifting of auxiliary shaft, so the compaction force is uniform, buffer performance is good and work piece can avoid damaging from rolling.
It uses 380V power to start and sleeve roller chain and chain sprocket to rotate two sets of worm gear reducer of 1:10 so as to slow down the transmission and ensure 10 rev/Min of main roller, with the characteristics of compact structure and smooth transmission.
