Hydraulic guillotine shearing machine and swing beam shearing machine

1．Shearing precision of guillotine shearing machine is higher than swing beam shearing machine :

（1）.Guillotine shearing machine can make shearing material more smooth, no burr

（2）. Shearing plate warping deformation of guillotine shearing machine is little, straightness accuracy more exact

（3）. After long-term work, knife rest of swing beam shearing machine prone to fatigue and deformation, and guillotine series don’t have this phenomenon

2．Shear angle

（1）．Shear angle of swing beam shearing machine is fixed，shearing speed can not be adjustable；

（2）．Guillotine shearing machine can make angle be adjustable: shear angle dilate, shear capacity increase , the shear angle reduced, shearing speed expedite, saving time and energy, effectively reducing the degree of bending sheet metal.

3． Advantage of rectangle edge of QC11Y series hydraulic guillotine shearing machine

（1）. the knife rest edge of swing beam shearing machine do camber movement when working, but guillotine shearing machine take on beeline movement, directly use rectangle blade of four sides edge, so that make the use life of edge increase 1 times.

（2）. Diamond-shaped blade cut sheet metal plate easily lead to cannabis-like distortion, cut the material, the more serious the more narrow, but rectangular blade will be able to avoid this defect

4．Life of oil cylinder: built-in cylinder semicircle of swing beam shearing machine hard to lubricate, and difficult to repair, but project cylinder of guillotine shearing machine charge oil by up and down cavity, no need to lubricate in addition, so have greatly increased use life.

that make the use life of edge increase 1 times.

（1）The shear angle of hydraulic swing beam shearing machine is fixed, can't adjust. Its work efficiency is same no matter in shearing thin plate or thick plate. That means, it has wasted a lot of electric power and work hour. For example, one shearing machine: QC12Y-35×2500, its motor power is 55KW, its stroke times is 4times/minute when shearing plate is 35mm, because the shear angle is not adjustable. So its stroke times is also 4times/minute when shearing plate thickness is 10mm.

（2）In order to minish the deformation of the rack and reduce the power of machine, the shear angle of swing beam shearing machine usually get the maximum value, but the biggish shear angle would make workpiece have prodigiouss  bending deformation when shearing thin plate
