Product Description

Description:

This machine droved by hydraulic to the sheet plate into rolls.
The upper roller can be shifted in the direction of horizontal and vertical
By adjusting the upper roller, you can obtain the function of pre-bending.
When making the rolls, by driving the motor and reducer (gear box) to make the two lower rollers action and finishing the rolls.

 

Machine construction:

The machine consist of upper lower equipment ,lower equipment and horizontal shift equipment, supporting equipment, main transmission equipment, reversing equipment, left and right side frame and the bottom support etc.
3-1.upper-roll equipment
    It's consists of main cylinders, upper roller bearing seats, the two main oil cylinders supply the needed bending force, the working force of main cylinder is 19.5MPa,the upper roller looks like drums.
The material is 45#,and the hardness is HB260-300,HRC45.


3-2.lower rollers and horizontal shift equipment
    The lower rollers is consisted of lower rollers, lower rollers bearing seats, lower roller input gears, lower roller sliding bearing, etc.
    The horizontal shift equipment drove by horizontal shifting motor, via the worm reducer. Worm wheel and worm bar also ball screws realize the function of symmetry rolling.
    The lower main motor supply the power to the lower rollers via the main transmission gear, lower roller input gear, open-type transmission shaft.
    The horizontal shaft equipment consist of :horizontal shifting motor, worm gear traducer, worm gear and worm bar, etc.
The material is 45#,and the hear treat hardness HB260-300,HRC45.




(lower roller)
3-3.supporting roller equipment.
    Consist of ball screws reducer construction.
    The supporting roller can be adjust up and down according to the amount of the loading force.

3-4. Main transmission equipment.
    Consist of main motor, V-belts, gear reducer, electro-hydraulic braking, etc.


3-5. Unloading equipment.
    The equipment consists of sliding seat, unloading cylinder, and this is to unload the working pieces.

3-6. Fixed, unlied-side frame, bottom frame.
   All the construction e welded by the sheet plates.

hydraulic system.

Consist of gear pump, Solenoid station, and the pipes circuits.
The solenoids made in Tai Wan.
The hydraulic system consists of 3 kinds of circuit, pressure adjusting circuit, symmetry circuit, speed circuit, etc.
 The pressure adjusting circuit adjusting the working pressure by main overflow valves, the system working pressure is 19.5MPa.Symmetry circuit can made the upper roller up &down by adjusting the throttle, and the symmetry accurate is ±0.20mm.
  The speed circuit control the unload side frame traversing and re-set, and the speed can be adjusted by the throttle.

Electrical control system.

It consists of electro-control-station (box), manual-handed bottom station, power source is 380V/50Hz.
  The main switch has the functions of short -circuit protection and the main motor over-loaded protection function. The motor directions can be controlled by A.C contactor, the control circuit controlled by PLC controller and the Touching Screen-Inter face system. The symmetry precession is very high, with the reliable  action, and long life. All control buttons indicators are fixed is the Electrical-control-box.

Main characteristics of the machine.

6-1.High precession of the top-end pre-bending .
   When pre-bending the top-end section, by changing the amount of the horizontal shifting of the up roll apply the pressing force directly to control the end shapes to realize the high precession end-pre-bending.
6-2.The working piece can obtain the precession from the very thin plate to the max. thickness.
6-3.NC control
   One person can operate the machine by NC system and thus improve the high efficiency.
