The leveler is mainly used to correct various specifications of plates. The leveling machine consists of many parts. The main components of the leveler are described below.

1. Rack section

The frame is the main body of the machine, which is composed of a base, a column, and a connecting beam, and is connected by 4 tension bolts to form a closed pre-stressed frame structure. The frame is a welded structure and is annealed after welding to eliminate internal stress. The frame has sufficient strength and rigidity to ensure a small elastic deflection under the maximum load and meet the needs of plate correction.

2. Roller part

The roller part is the working part of the machine, including work rolls and support rolls. In order to meet the rigidity requirements of the work rolls, 3 rows of upper and lower support rolls are specially set up.

The upper and lower support rollers are equipped with an inclined iron adjustment mechanism, which can be manually adjusted to their upper and lower positions to ensure good contact with the work roller. The upper and lower support rollers are in a whole row, and the support roller base is split, with reasonable structure. The upper support roller can also be drawn out separately along the machine longitudinal direction, which can be quickly replaced, which greatly reduces online maintenance time.

3. Movable beam

The movable beam is a single-piece closed welding structure, which is annealed as a whole after welding to eliminate internal stress. It has sufficient rigidity and strength to ensure the flattening accuracy of the plate and reduce the number of flattening. Using the guide surfaces on both sides of the sliding block, the movable beam can move up and down and corners, and the movable parts such as the movable beam can be drawn out from the frame of the frame laterally, which is easy to maintain and repair.

4. Press down the corner mechanism

The pressing mechanism and the corner mechanism are integrated. The depressing corner mechanism is installed on the upper part of the frame and the connecting beam, using group technology, using two sets of the same moving system, driven by 2 brake motors, and 2 reducers driving 4 worm pairs and 4 screw pairs , So that the movable beam can be accurately and automatically positioned and quickly swing. Start 2 sets or 1 set of power system to realize the parallel lifting or tilting of the movable beam and the upper work roll, which can level plates of different thicknesses and materials, and achieve the best flatness requirements. The upper end of the movable beam is equipped with a balancing device to eliminate the screw gap and ensure the leveling quality. Start two press-down motors, and drive the screw rod to move up and down through the reducer, gear coupling, transmission shaft, and worm gear reducer to realize the parallel lifting of the movable beam mechanism. Start a single pressing motor to realize the swing of the movable crossbeam mechanism, which can make the movable crossbeam accurately positioned, which is more conducive to the leveling of the plate.

5. The main drive system

All working rollers in the upper and lower rows and the upper rollers on both sides are equivalent active rollers. The main drive system consists of 9 AC variable frequency motors through a coupling-reducer-universal coupling-work roll device to make the equipment rotate. Two sets of speed reducers are distributed on both sides of the machine. One four-in and four-out drives all the lower straightening rolls, and the other five-in and five-out drives all the upper straightening rolls. This is the "equivalent full-split main drive" patented technology.

6. Dry oil centralized lubrication system

The lubrication system of this machine includes three parts: thin oil splash lubrication in oil pool, concentrated dry oil lubrication, and manual regular lubrication. Except that the reducer adopts thin oil splash lubrication from the oil pool, and the guide surface and movable pin adopts manual regular dry oil lubrication, all the lubrication points of this machine mainly adopt the centralized dry oil lubrication of the electric double-line oil feeder.

7. Electrical control system

This machine is equipped with a main and a sub-operating console, which are placed on both sides of the equipment. The main console uses PLC, contactors, micro relays and other components. The electrical control system adopts 380V, 50Hz AC power supply, the main circuit adopts contactor control, and the control circuit adopts electrical control.

8. In and out roller table

The feeding and discharging roller device is equipped with a power driving device, and the moving speed is matched with that of the main machine, which is reliable in operation and strong and durable.
