The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Fig. 1 and Fig. 3 are common, shell fragment bending equipment, comprise frame 1 and for clamping by the workbench 11 of bent spring plate, in frame 1, be rotatablely equipped with the rotating shaft being driven by the first power set, the end face of rotating shaft is installed with a positioning core axle 6 and a bending boss 7, positioning core axle 6 and bending boss 7 are all identical with the bearing of trend of the axis of rotating shaft, the axis of positioning core axle 6 is consistent with the axis of rotating shaft, the axis of the position deviation rotating shaft of bending boss 7, forms the bending gap of shell fragment between positioning core axle 6 and bending boss 7.

In the present embodiment, in frame 1, be rotatablely equipped with two rotating shafts, the switched in opposite of two rotating shafts, two rotating shafts are in transmission connection by gear pair, in the first rotating shaft 2, be installed with and in the first gear 3, the second rotating shafts 4, be installed with the second gear 5, the first rotating shafts 2 and connect the first power set.This equipment can carry out bending to two of shell fragment ends simultaneously.Certainly, rotating shaft can be set to one, can be used for single head shell fragment to carry out bending.
