This machine adopts PLC programmable control system, grating ruler,
digital display for upper roller vertical elevation, horizontal
movement’s distance, it has simple and reliable manipulation .
grating ruler is responsible for synchronical movement of two heads
of upper roller, it gets feedback to PLC, while PLC auotmatically
start and close motor direction valve to adjust elevation of two
heads to get precise synchronical movement .
Supporting roller device of this machine is composed of supporting
roller, adjusting mechanism, and wedge mechanism.
The supporting roller made of 45 steel is treated by quenching and
tempering,and its hardness is HB217-255.The hardness of roll
surface is less than the surface hardness of the lower roller,and
the surface is used turning spiral groove , effectively prevents
the oxide skin, impurities damaging the lower roller when rolling
The supporting roller has totally 4 rollers in one group.According
to the load size when rolling, to adjust up and down.
Reasonbale lubrication of surface can reduce power consumation and
increase using life. Oiliness lubrication and fixed-time
lubrication are chosen according to different conditions. Oiliness
lubrication is used in main drive hard gear reducer, qorm gear in
horizontle movement device and worm gear reducer .
While motorised dry oil pump concentrate lubrication is used in
upper roller rolling shaft , down roller rolling shaft and upper
roller ‘s horizontal shaft.
Overturning device consists of overturning rack, overturning tank
pin, frame etc.. Overturning cylinder adopts with a single-stage
cylinder,And the cylinder piston rod is treated with Plate
Overturning device turns the side rank over,and make it easy to
take out the workpiece along the roller axle direction easily.Then
complete the discharge work steps.After the overturning rack
reset,you can start to roll another plate.
