There are two types of this equipment operating modes: one is the processing that wiping board mode is mainly used for plate burr and plate face greasy dirt,
One is the amendment that correction mode is mainly used for camber, operator can select Working mould according to actual working condition
Formula.
Electromagnetism feeding device
The plate for needing camber to align mainly is hoisted on rollgang by electromagnetism feeding device by magnechuck.It is main
It to be grouped as by magnechuck, vertical lift part, horizontal transferred unit.Level transfer part is moved to strong by motor when work
Above straight panel material, vertical lift part, which is fallen after magnechuck adsorbs plate, rises to setting position, is sent by horizontal transferred unit
Above to rollgang, the transfer of steel plate level is completed, plate is vertically fallen and is placed on rollgang.
Entrance rollgang
It is made of roller bed type transport portion and pinch roller segment, steel plate is delivered to camber apparatus for correcting.When work, by
Electromagnetism feeding device is placed on steel plate above roller-way, and the back of a bow of camber will be in fore side；Pinch roller is depressed, starting entrance is defeated
Roller-way is sent, billot steel plate is sent into hydraulic straightening machine.Pinch roller upper roller is passive, band position detection encoder.
Hydraulic straightener
Push for camber is corrected.Mainly by workbench part, carrying roller part, hydraulic drive correction section, solid
Determine the compositions such as stopper portions, lifting deck portion.When work, billot steel plate is sent to hydraulic straightening machine from entrance rollgang
Into until roller-way stops and lifts pinch roller when suitable position；The carrying roller on correction machine platform is fallen, makes to fall under billot steel plate strong
On the platform of positive machine (platform surface covers engineering plastic flitch)；The correction hydraulic cylinder for starting straightening machine, pushes billot steel plate to platform
The fixed stop of side, the stopping when billot steel plate will be contacted with fixed stop start cover board lifting hydraulic cylinder, cover board are fallen
Down and certain gap is kept with billot steel plate；Driving correction hydraulic cylinder again, continues after shifting billot steel plate onto fixed stop
Apply thrust, the camber in billot steel plate certain length is corrected.Correction hydraulic cylinder is retracted, the support on cover board and platform is risen
Roller depresses pinch roller, while starting entrance, outlet rollgang, and billot steel plate is continued to be sent into suitable position, repeats reaping hook
Curved corrective operations process, until the camber of billot steel plate is corrected.
Export rollgang
It by roller bed type transport portion and pinches roller segment and forms, the billot steel plate that need to correct is moved forward and backward, or having rectified
Billot steel plate after just is delivered to electromagnetism device for discharging, and completes the detection of camber.Pinch roller upper roller is passive, band position detection
Encoder.When work, after the billot steel plate that finishes of correction fully enters outlet rollgang, roller-way is stopped, conveying roller it
Between retainer idler wheel by billot steel plate hold up and with conveying roller be detached from, by billot steel plate move on to setting outlet rollgang side
Guiding ruler whether the billot steel plate after correction is determined by the gap between billot steel plate and guiding ruler using light-illuminating method
Reach quality requirement.
Quality requirement is not achieved in billot steel plate after such as correcting, and billot steel plate is returned to the position before determining quality, support
Material roller is fallen, and billot steel plate is returned on entrance rollgang, carries out reaping hook again by starting outlet, entrance rollgang
Curved correction, until camber correction is reached quality requirement.
Billot steel plate after such as correcting reaches quality requirement, and retainer idler wheel is fallen, by electromagnetism device for discharging by billot
It slings, starts transverse-moving mechanism for billot steel plate and be transferred to discharge position.
Electromagnetism device for discharging
Electromagnetism device for discharging is used to the billot steel plate after camber is aligned being hoisted to discharge level by magnechuck
It sets.Mainly it is grouped as by magnechuck, vertical lift part, horizontal transferred unit.Level transfer part is moved by motor when work
After moving to outlet rollgang aligning above plate steel plate, vertical lift part, which falls to rise to after magnechuck adsorbs plate, to be set
Positioning is set, and is sent by horizontal transferred unit to discharge position, completes the transfer of steel plate level, plate is vertically fallen to be placed on and is unloaded
Expect platform position.
Hydraulic system
Hydraulic system has hydraulic station and corresponding pipeline and oil cylinder to constitute, using constant flow paddle pump and high-quality element, highest
Operating pressure 12Mpa.Hydraulic station provides hydraulic power for correction unit.
Pneumatic system
Pneumatic system handles three big elements, solenoid directional control valve, PU pipeline and corresponding product cylinder by gas source.
Electric control system
Electric control system uses dcs.Whole system high degree of automation, response is rapid, control means
It is advanced.Can manually and automatically it be switched.Control core is PLC programmable controller.Control cabinet good seal has fan logical
Wind.Component connection and reasonable arrangement in cabinet, it is easy to repair.
Hot rolled plate camber corrective operating procedure:
