When the rotating gear 8 on the sliding rod 40 is in contact with the rack 4 on the mounting rod 3 on the mounting frame 2, the rotating gear 8 is meshed with the rack 4, the rack 4 forces the rotating gear 8 to rotate, the rotating gear 8 rotates to further drive the rotating rod 9 to rotate, when the rotating rod 9 rotates to a horizontal state, the rack 4 is separated from the rotating gear 8, the guide rod 48 on the rotating rod 9 props open the two clamping plates 46 and then enters the groove-shaped structures on the clamping plates 46, the clamping plates 46 clamp the guide rod 48 under the pushing action of the clamping springs 47 on the clamping plates 46 to further prevent the rotating rod 9 from falling down, then the power motor continues to work to drive the sliding rod 40 to continue to move forwards, and then the guide rod 48 enters the hole-shaped structure at the front end of the mounting rod 3 to further guide the rotating rod 9 stably;

when dwang 9 rotates to the horizontality, the thread rolling machine begins work, then along with the further advance of dwang 9, the shaft-like position of the hex bolts of grip block 25 centre gripping stretches into the operating position between two rollers of thread rolling machine on, at this moment, slide bar 40 moves to the rightmost end, separation blade 41 position top at this moment installation pole 3 lower surface mounting has a proximity switch, when this proximity switch senses separation blade 41, motor power 36 stall, gear motor 14 antiport, and then grip block 25 opens, the thread rolling machine thread rolling roller closure rolls the thread to the hex bolts.

Then, after delaying for a few seconds, for example, delaying for 4 seconds, the thread rolling machine stops thread rolling after thread rolling is finished, two thread rolling rollers of the thread rolling machine slightly open, for example, open by 8mm, then the speed reducing motor 14 rotates in the forward direction, the clamping block 25 moves inwards to clamp the hexagon bolt, the power motor 36 rotates in the reverse direction, the sliding block 39 moves leftwards, the sliding rod 40 moves leftwards, after the rotating rod 9 rotates to the vertical state under the action of the rack 4 and the rotating gear 8, the rotating gear 8 is separated from the rack 4, when the hexagon bolt reaches the position above the second conveyor belt 27 for the second time, the blocking piece 41 on the sliding rod 40 approaches the second approach switch 5 for the second time, at this time, the speed reducing motor 14 rotates reversely, the clamping block 25 moves outwards under the reverse rotation action of the rotating disc 22, so that the hexagonal bolts are loosened by the clamping block 25 and fall on the second conveyor belt 27 for conveying;

in the utility model, the clamping block 25 can be in an open state when not being acted by the rotating disc 22 by additionally arranging springs in the telescopic barrel 17, specifically, three springs are additionally arranged and radially and uniformly distributed on the inner bottom of the telescopic barrel 17 by taking the center of the bottom of the telescopic barrel 17 as a circle center respectively, the inner ends of the springs are connected with the bottom of the telescopic barrel 17, and the outer ends of the springs are connected with the clamping block 25;

because the distance between the clamping blocks 25 is larger than the width of the upper part of the hexagon bolt, the error of a part of hexagon bolts can be counteracted, and the clamping of the hexagon bolt with slight position deviation is realized;

then the rotating rod 9 continues to move leftwards, the guide hole 43 on the rotating rod 9 is meshed with the guide rod 42 on the mounting rack 2, the guide rod 42 guides the rotating rod 9, and when the baffle piece 41 approaches the first approach switch 5 again, the processes are circularly carried out, and next thread rolling feeding is carried out;

the above-mentioned process of constantly circulating, and then realized carrying out the hexagonal screw raw materials through placing piece 28 on conveyer belt 26 and adding, carry out the off-the-shelf discharge of hexagon bolt after the thread rolling through No. two conveyer belts 27.
