KJF series rotary shear cut to length line
Hydraulic rotary shear cut to length line,metal coil uncoiler four hi l eveler rotary shearing line,steel coil decoiler straightener rotary shearing line,sheet plate rotary shear cutting line,our precision production line equipment with stacking system,application for hot rolled steel,cold rolled steel,stainless steel,silicon steel and other metal steel coils
rotary shearing line in which sheet stock is fed by a feeder to a rotary shear for fast cutting by its rotating cutting shear, a synchronous speed and a synchronization length are calculated by an arithmetic unitLIt is supplied with the cutting length and the average feed rate of the sheet stock. Reference pulses of a frequency corresponding to the synchronous speed. The synchronization length is provided t如a first numerical controller for contolling the feeder. Asecond numerical controller for contrlling the rotary shear. The first numerical controllr controls the feeder to feed the sheet stock ata speed higher,or lower than the synchronous speed in such a manner that when the sheet stock is fed at the synchronous speed, the length of the sheet stock short or excessive of the cutting length before its cutting is compensated for within a cuting period.
The second numerical controller controls the rotary shear to rotate its cutting edges at a speed higher or lower than the synchronous speed in such a manner that when the cutting edges are rotated at the synchronous speed, the circumferential length of the locus of each cutting edge short or excessive of the circumferential length of its 360degree rotation is compensated for within the cutting period.
