Swing shearing device

The invention discloses a swinging cutting device, comprising an installing soleplate, a gear transmission mechanism, a cutting mechanism, an entrance side conveying mechanism and an exit side conveying mechanism; wherein, the gear transmission mechanism consists of a servo motor, a reduction box, a driving bevel gear and a driven disc gear; wherein, the servo motor and the reduction box are fixed on the soleplate; the driven disc gear is horizontally assembled on the soleplate by a bearing and is then connected with a shaft by a spline; the top is fixed with the disc frame of the cutting mechanism; the cutting mechanism is arranged on the disc frame of the cutting mechanism; the servo motor drives the reduction box so as to drive the driving bevel gear to rotate; the driving bevel gear and the driven disc gear are meshed, so as to drive the cutting mechanism by the driven disc gear to freely rotate in a range between +45 degrees and -45 degrees corresponding to the soleplate. The swinging cutting device can
