The present invention is achieved in that a kind of new many rates of shear plate shearing machine, and comprising: electrical appliance part, braking motor, tertiary gear speed change are transmission device; Main shaft, eccentric wheel, compound sleeve, chain bar, bearing pin are draw-gear; Tight time bolt, thrust swivel nut, locking nut, holder, slip arm base are rear-mounted blade clearance adjusting device; Clamping screw, centering bolt are slip arm base locking and centering parts; Garment bag, presser feet axle, tight fixed bolt, presser feet seat are plate cutting no marking devices; Pressing plate, spring leading screw, stage clip bearing, front beam are feeding pressure mechanism; It is characterized in that: described electrical appliance part instruction braking motor work, increase the round and smooth motion of shearing force eccentric wheel on main shaft by the tertiary gear speed change, the chain bar traction upper tool post external by compound sleeve moves up and down, and realizes shearing the plate purpose by upper tool post blade and lower slide blade at last.

The variation of the initial one-level pinion number of teeth in the described tertiary gear speed change gear can realize the requirement of many shear rates with the braking motor displacement.

Described tight time bolt, thrust swivel nut, locking nut act on the holder and are used, and can realize slip arm base lower end move left and right, reach the required gap blade of shearing plate.

Described presser feet seat is welded on the pressing plate lower end, and built-in presser feet axle has tight fixed bolt locking, and garment bag is a tight fit on the presser feet axle, and when shearing binder, plastic sheath is to the sheet material no marking.

Technical scheme of the present invention is: accuse braking motor by electrical equipment, increase torsion output by the tertiary gear speed change, eccentric wheel rotates on the drive shaft, round and smooth moving through compound sleeve, drive chain bar traction upper tool post and do up and down lock formula motion, be used with the lower slide blade, thereby reach shearing function.

The invention has the beneficial effects as follows: do not have the mechanical clutch part, simple in structure, operation is dexterous convenient, and braking motor running during shear, otherwise shuts down, and is energy-conservation; The tertiary gear speed change is changed the one-level pinion that changes the number of teeth, can realize the needs of many shear rates; Slip arm base is assemblied on the wallboard, and rearmounted holder adjustment structure is arranged, and gap blade is adjusted simple to operation; The optimal design of pressure plate structure makes to be sheared the plate no marking.
