Product Description

W11Y series Special rolling machine for oil tank truck has 3 symmetrical rollers. The upper roll is located at center of two lower rolls and is directly driven by dual hydraulic cylinders to move vertically. The output gear on main speed reducer is used to mesh the gears of both lower rolls for rotation so as to provide torque for rolling plate. Metal plate is located among three working rolls and subsequently continuously bent under pressure of upper roll and rotation of lower rolls to generate permanent plastic deformation on plate so as to roll the plate to required shape such as cylinder, taper cylinder or arc.  W11Y series is not able to prebend the plate end during the rolling process,the but it can correct the roundness after welding the cylinder. The vertical moving of upper roll is monitored by a displacement sensor and shown by a digital meter, so the displacement and position of upper roll can be directly observed and working efficiency and product quality are therefore increased.

Product Features：

This Special rolling machine for oil tank truck is composed of upper roller device, lower roller device, frame, chassis, main transmission device, overturning device, supporting roller device, balance device, hydraulic system, electronic control system, etc.

The upper roller device is composed of main cylinder, upper roller bearing seat, upper roller, double row self-aligning bearing, etc.

The two main cylinders provide the pressure required for rolling sheet metal.

Double row self-aligning bearings adopt low speed and heavy load self-aligning roller bearings.

The upper roll is drum-shaped, and the load coefficient of the maximum pressure of the upper roll is 0.7 uniform load to compensate the deformation deflection of the upper roll.

The lower roll device consists of lower roll, lower roll bearing seat, lower roll input gear, lower roll sliding bearing, etc.

The main drive of the lower roller provides power, through which the output gear, the input gear and the open drive torque are transmitted to the lower roller.

The supporting roller device is composed of supporting roller, worm wheel and worm mechanism, wedge mechanism, etc.

The main transmission device consists of a main motor, a triangular belt, a cylindrical gear reducer, an electro-hydraulic push rod brake, etc. The output gear drives two lower roll gears.

The main drive can be reversed to provide rolling torque for sheet rolling.

The overturning device is composed of a sliding pillow, an overturning cylinder, etc.

Chromium plating treatment for overturned cylinder piston rod.

The overturning device is convenient for the product to be taken out along the axial direction of the roll.

Fixed, inverted frame, chassis are welded steel plate, stress removal after welding.

The balancing device consists of balancing cylinder and balancing bracket, which guarantees the balance of the upper roll and eliminates the deflection of the upper roll.

Two supporting cylinders top, balance cylinder down pressure. Keep the upper roll in a horizontal state.
