Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 3, a swing shearing machine described in the utility model includes a connecting and feeding table 10, a front end arc guide rail 12, a rear end arc guide rail 11, a rotary knife rest 13, and a rotary drive motor 14. The front end and the rear end of the rotary tool rest 13 are rail-connected with the front arc guide rail 12 and the rear end arc guide rail 11 respectively, and the rotary drive motor 14 drives the rotary tool rest 13 around the front arc guide rail 12 and the rear end The arc-shaped guide rail 11 rotates and swings; the front and rear ends of the rotary knife holder 13 are respectively provided with a pair of upper and lower cutters 15 and 16 which are offset up and down; The connecting platform 101 has several balls 100 distributed on the connecting platform 101 .

The upper cutter 15 is fixedly mounted on the rotary knife frame 13, the lower cutter 16 is connected with a cutter driving mechanism 17, and the cutter driving mechanism 17 drives the lower cutter 16 to move up and down; the side of the lower cutter 16 is provided with elastic The touch plate mechanism, the elastic touch plate mechanism includes a touch plate 182, a push rod 181, a spring 180 and an inductor. The touch panel 182 , the sensor is disposed on the touch panel 182 . After the plate enters the connecting and feeding platform 10, the plate can slide smoothly on the balls 100 of the connecting platform 101, which is convenient for feeding and is not easy to cause deviation and scratches. When cutting the plate, the cutter drive mechanism 17 drives the lower cutter 16 to move, the touch plate 182 contacts the bottom surface of the plate 182, and the touch plate 182 plays the role of elastic contact with the plate 182 to avoid deformation or deviation of the plate, and the sensor acts as a sensor The effect on the plate is convenient for the control system to control the action of the cutter driving mechanism 17, and the lower cutter 16 and the upper cutter 15 work together to cut the plate.
