When the threaded hole and the upper thread 43 are disengaged, under the action of the compression spring 128, the sliding plate 123 still pushes the connecting rod 122 to slide, further causing the sliding rod 53 in the groove 127 to move downward, so that the wire rope 54 continues to cut the blank. During cutting, since the inner surface of the sliding rod 53 contacts the blank first, burrs cannot be produced at the cutting point. This structure can reduce the appearance of burrs.

[0030] The outer surface of the rotating rod 42 is fixedly connected with a stop sleeve 120, and both sides of the top of the connecting screw block 55 are fixedly connected with push rods 56.

Through this structure, the cut blank can be quickly conveyed, further improving its production efficiency.

[0032] The working principle of the present invention is as follows: first, the blank to be cut is conveyed to the bottom of the limit assembly 5 through the horizontal conveyor 2, and then the rotating motor 41 is started to rotate, thereby driving the rotating rod 42 to rotate, and under the connection relationship between the lower thread 44 and the connecting screw block 55, the box body 51 moves downward, and at the same time, the connecting plate 129 moves downward under the action of the upper thread 43, and the connecting plate 129 drives the sliding plate 123 to slide downward on the inner surface of the through sleeve 121 through the limit rod 124, so that the sliding rod 53 in the groove 127 moves downward synchronously with the limit assembly 5, the box body 51 wraps the blank, the baffle 52 contacts the surface of the blank, and the wire rope 54 starts to cut the blank, when the threaded hole on the connecting plate 129 disengages from the upper thread 43, and then the rotation of the rotating motor 41 is stopped, and the compression spring 128 is still in a compressed state at this time, and the compression spring 128 pushes the sliding plate 123 to slide on the inner surface of the through sleeve 121 With continuous sliding, the limit rod 124 slides downward on the inner surface of the sliding groove 125, so that the pull rod 126 drives the sliding rod 53 to move downward, and the wire rope 54 continues to cut the blank until the connecting plate 129 falls above the stopper 120. At this time, the sliding rod 53 contacts the top of the horizontal conveyor 2, thereby completing the cutting of the blank. Then the rotating motor 41 is started to rotate in the opposite direction, thereby driving the limit assembly 5 to move upward, and the top rod 56 on the connecting screw block 55 pushes the connecting plate 129 to slide upward, while making the sliding plate 123 move upward and further compressing the compression spring 128. The threaded hole on the connecting plate 129 contacts the upper thread 43 and is threadedly connected again, and the initial state is restored. At this time, the electric telescopic rod 8 in the fixed frame 7 is started to extend, further making the top plate 10 slide on the outer surface of the slide groove rod 11, and the push plate 9 sends the cut blank to the longitudinal conveyor 6 for transportation.
