Embodiment

Specific embodiment of the present utility model is made a detailed explanation below in conjunction with the accompanying drawings.

A kind of flyweight is cut, including motor 1, the first reductor 2, bent axle 8, frame；The frame is included provided with upper cutting die 6 Upper spider 5 and the lower bearing bracket 3 provided with lower cutting die 7, and a pair of shear blades, the frame are installed on upper cutting die 6, lower cutting die 7 It is respectively arranged on the left side and the right side the sliding block to be moved reciprocatingly by the zone of action motivation frame of motor 1, the first reductor 2 and bent axle 8 12,13, described reciprocating motion includes the gyration of upper spider 5 and the anterior-posterior translation motion of lower bearing bracket 3, the lower bearing bracket Bottom is provided with the linear slider 15 for lower bearing bracket anterior-posterior translation, is provided between the upper cutting die 6 and lower cutting die 7 and is used for shear blade Shearing and the vertical slipper 16,17 of separation, the flyweight, which is cut, also includes the revolving support 4 for being located at the lower bottom of cutting die 6, and driving The drive system that upper cutting die 6 and lower cutting die 7 rotate, the drive system include oscillating motor 10, the second reductor 11.Described Drive system is connected by Hooks coupling universal coupling 14 with lower cutting die 7.Rotatable connection between the upper spider 5 and upper cutting die 6, institute State rotatable connection between lower bearing bracket 3 and lower cutting die 7.

Flyweight provided by the utility model cuts operation principle：

1st, flying shear：Motor 1 is rotated by reductor 2 with dynamic crankshaft 8, and bent axle 8 drives upper spider 5 to do gyration.Wherein The gyration of upper spider 5 includes moving forward and backward in X-direction and the up and down motion in Y-direction, i.e., upper cutting die 6 passes through upper machine Frame 5 does gyration；Upper spider 5 drives lower bearing bracket only to do the anterior-posterior translation in X-direction and moved by sliding block 12 and sliding block 13, i.e., Lower cutting die 7 does anterior-posterior translation motion, and the gyration of upper cutting die 6 and the anterior-posterior translation motion of lower cutting die 7, which coordinate, realizes flying shear Shear action.

2nd, flyweight is cut：Revolving support 4 is provided with the lower bottom of cutting die 7, oscillating motor 11 starts, and by the second reductor, Lower cutting die 7 rotates, and due to the effect of vertical slipper 16,17, upper cutting die 7 follows cutting die 6 to rotate together, it is achieved thereby that pendulum is cut Function, motor 1 and oscillating motor 11 coordinate, and the winged shear action of cutting die is coordinated the spinning movement of cutting die, and THE ADIABATIC SHEAR IN goes out Steel plate of different shapes, in the angular range of restriction, cutting die can work in any angle, if changed to cutter, Shearing shape can also be R shapes or waveform, widens the production range of flying shear line, improves production efficiency.

Principal character of the present utility model is the foregoing described, it should be understood by those skilled in the art that, the utility model is not It is restricted to the described embodiments, on the premise of spirit and scope of the present utility model are not departed from, the utility model also has respectively Kind changes and improvements, these changes and improvements are both fallen within claimed the scope of the utility model, and the utility model will The scope of protection is sought by appended claim and its equivalent thereof.
