1. Basic parameters

The device has outstand performance, the structure is compact, operate is easy. Up roller lift and turnover device used hydraulic drive. The motor drives two bottom rollers. This is the main drive and it realized by motor drive speed reducer with the help of triangle belt. The rolling flexibility is good, lift up roller test use shift sensor, and the shift shows as figure. Those about these raise producing efficiency and product quality.

II.The structure of machine

1. Up and bottom lifting device of up roller

Using double oil vat drive directly, it’s max working pressure is 19.5Mpa. Rolling bearing and bearing base installed on the two sides of up roller. Position rod lifted up and bottom along vertical guides with the help of bearing. Installed shift sensor on the ends of bearing, and then to test elevate position. And show as figure. The material of up roller is 45# steel, and it done heat treatment.

                                                                                                               

                                           

               Up roller

1. Driving device of bottom roller

The bottom rollers drive motor with the help of triangle belt. The bottom roller transmitted power to a three level gear speed reducer. The gear speed reducer revolves bottom rollers with the help of output gear and bottom rollers gear. The material of bottom roller is 45# steel, and it done heat treatment.

 

                    Bottom rollers

1. Up roller balance device

Lifting up roller to highest place, the balance beam ( on the ends of up roller) fix up roller. So that the up roller on balance state with the help of bearing base and balance beam, and then we can easy to turnover and close turnover bearing base. The up roller lift to the highest place ,and this can test by SQ.

 

Turnover bearing

1. Base board

Using wield closed type frame base, it’s functions is good as the example bend-prevent, torsion-prevent,and inertia moment is large. So it’s easy to install machine and move.

1. Hydraulic system

Hydraulic system composed of gear pump, series of valves, accessory pipeline components and so on.

Hydraulic valve choose from Taiwan. The arrangement of pipeline is very easy, defend and shake bottom is easy too.

The system composed of three circuits, press adjust circuit, Symmetrical circuit, speed circuit.

Press circuit adjusts working pressure with the help the main valve. The working pressure is 19.5Mpa.

Synchronization circuit realize rough synchromesh bypass flow of up and by bottom lift split-flow and throttle valve. Readjusting up and bottom speed by throttle valve, and tested by shift sensor, synchromesh position accuracy attached 0.20mm of up roller.

Controlling turn over and resume of machine rack by speed circuit, and adjust speed by throttle valve.

1. Electrical control system

Electrical system composed of electrical cupboard, button box. The power is AC 3-Phases

380V/50HZ. Main switch has the function about short protection and overload protection. The move distance of up roller test by sensor, show as figure, so it show directly, operate easily, and improve power.

B.JB/T897-1998<model and base parameters of medium, small-size rolling machine>

C .JB/T9971-1999<noise limit of rolling machine>;

D.GB8768-83<The common technical requirements of hydraulic system>;

E. Chinese current standard of electrical control of device

1. The supply range.

A. Device body

B. Hydraulic device

C. Electrical control device

D. Technical files, reference, certificate, electronic drawing, install drawing, container loading list.

V.Main advantages of the device

1. Bottom roller drive torsion with the help of triangle belt, and has the function to overload protect.
2. Base board using closed type frame. It’s bend prevent and torque prevent is good. And it’s easy to

install and move.

1. Up roller adopts axis adjustable bearing, the resistance of friction is small, the rolling range is wide.
2. Hydraulic valve choose from Taiwan, and it’s installed, defended, and do test are very easy.

E. Hydraulic synchronization circuit system adopted split-flow valve, tested by shift sensor, showed by figure. The accuracy attached +0.20mm.
