Product Description

Product Features：

This machine is a W43 series standard roll plate leveler with support. It consists of a power part, a main engine part, and electronic control part.

1. Power part

The power part consists of leveling power base, reducer, YWZ brake, coupling, power distribution box, coupling bush, universal transmission shaft, etc.

The main motor is equipped with a high-power DC speed-regulating motor and analog control system, which can adjust the speed at multiple levels.

Starting current is less than rated current, starting torque is greater than rated torque, especially suitable for continuous high load start, responsible for providing leveling power to the main engine.

2. Host part

The main engine part adopts a four-fold roll assembly structure, which consists of a welding frame, integral gantry frame, 15 leveling roll shafts (top 7 bottoms 8), upper and lower roll shafts, beams, idlers, supports, worm wheel and worm drive upper roll lifting and pressing device, etc.

The leveling roll is a forging made of Gr15 and the supporting roll is made of 42CrMo. The whole frame tempering treatment, leveling work roll, supporting idler processing technology: rough turning + tempering + semi-finishing turning + intermediate frequency quenching + straightening + grinding + hard chromium plating + grinding.

To ensure that there is no radial and axial movement of the working roll, the end of the roll is connected with the roll seat by double-row heavy-duty aligning bearing, the end nuts are tightened, the hand-pressure oil pump is centralized lubricated, and the running resistance is small.

The two sides of the upper roller axle seat are arc track structures, which can adjust the gap between the inlet and outlet of the upper and lower leveling rolls.

The upper and lower rows of leveling work rolls are provided with two sets of support brackets and supporting rollers, whose height direction is adjusted by an inclined wedge to compensate for the deflection caused by the force of the leveling work rolls, to improve the strength and rigidity of the leveling work rolls (it is usually not necessary to adjust after the machine debugging is completed).

DC motor power through the coupling, reducer, power distribution box, universal joint drive shaft, and upper and lower row of work rollers connected, driving the upper and lower work rollers to actively run, high level and smoothness of sheet metal.

3. Electronic control part

The unit is centrally controlled by an electrical operating table. The electronic control part includes the operating table, DC control cabinet, and its supporting components.

It can control the parallel and reverse operation of the main motor, adjust the leveling speed, adjust the gap between the upper and lower rollers as a whole, and adjust the gap between the import and export separately.

The power supply is 380V, 50HZ AC power supply, and the ambient temperature is -10℃～40℃.
