Abstract (en)
A double-sided folding machine comprising: a lower stand comprising a lower tool set, comprising a lower clamping tool and a lower bending tool; an upper stand comprising an upper tool set, comprising an upper clamping tool and an upper bending tool; an eccentric mechanism connecting the lower stand to the upper stand, comprising a shaft mounted on lower stand and a wheel with off-centred parallel axis, wherein the shaft is off-centred mounted in wheel in respect of the geometric axis of wheel upon which is mounted the upper stand; wherein the lower and upper clamping tool sets are displaceable in relation to each other by a horizontal offset between a first position for folding upwards and a second position for folding downwards, wherein the geometric axis of wheel rotates off-centred in respect of shaft to displace the upper stand by a horizontal distance of at least said horizontal offset. Also, method of bending sheet metal thereof.
