ysd Cut to length line

Detailed Product Description

YSD Cut-to-length line summarization

Cut-to-length line is semi-automation  production line which it is adapted to produce hot rolling mild steelstainless steel. This production line is consist of coil carDecoilerAuto feeding device loop bridge ,Rectify platformStraightening machineshearing machineConveyorstacking machineHydraulic elevator platform etc. this machine is adopted centralized control, single/tandem operation, touch screen man-machine interface which it easier to coilfeedingcut to length according to require with countoperate repetition position of upper roll of straightening machine etc. Uncoiler is adopted double-head with clutch which it can be achieve activepassive uncoil operate modeThe arrangement of whole line is very compact Pre-straightening machine and straightening and trimming machine adopt the technology of DC speed technology, thus online adjustment of straightening speed is easily achieved. Encoder is used for measurement of shearing length with high accuracy. Satisfactory straitening results can be achieved through adjusting extension angle of straitening machine according to the plate thickness.

Technique flow

Take off the external packing of the coil, then put the coil onto the coil stacking platform; transport the coil to the decoiler by coil car. Put the decoiler to the proper position through operation station. Expand the coiler core and hold the coil tightly.

Inch the decoiler and put the material edge to some proper position. Press down the hold-down rack of the feeding device, take off the packing belt on the coil, operate lower shovel and anti-bending device, draw out the coil head and bring it to the pre-straightening machine.

Press down upper roller, inching straightening machine when the upper roller pressed to set-position. After checking the straightening result, go on inching the machine to let the material go into the edge trimming machine and press down the hold-down rack of the trimming machine. Make the pre-straightening machine and edge trimming machine be in combined operation, bring the edge scrap into the scrap winding machine.

The plate after trimming go into straightening machine and shear after passing through Loop Bridge and hydraulic centering platform and the plate head will be cut. Then input the value of required length and cutting numbers on touch screen, operate the straightening machine and shearing machine with single-action, and cut one piece to check the accuracy. After checking, if all item have meet the demands, then turn to combined operation, the production line start to work continuously.

When it reaches to the set cutting number, the whole line will pause, and it will recover to work after manual interference.
