According to the bolt processed by the invention, the bolt forms a semi-finished product in the process of annealing process, the semi-finished bolt comprises a round metal block, a cylinder is fixed on the bottom surface of the metal block, the outer diameter of the round metal block is the same as the inner diameter of the placing groove 59, the outer diameter of the cylinder is the same as the inner diameter of the first through hole 56, and in the process of annealing process, the metal has good plasticity, so that the periphery of the metal block is firstly pressurized to form a shape with four arc-shaped corners and four straight sides.

The working principle is as follows: the semi-finished bolt to be machined is placed in the placement groove 59, such that one end of the cylinder of the bolt passes through the first through-hole 56 and is positioned in the second rotary post 44, by pushing any one of the pressing plates 27, one end of the pressing plate 27 moves towards the direction close to the metal block, so that the third rack 22 is driven to move, the third rack 22 drives the fifth gear 40 to rotate, the fifth gear 40 rotates to enable the other three third racks 22 to move synchronously, and then, one ends of the four pressing plates 27 are brought close to each other, and four sides of the metal block of the bolt are pressed, thereby achieving the purpose of shaping the metal block of the bolt, the four extrusion plates 27 synchronously move to extrude the metal block, thereby not only leading the metal block to be rapidly shaped and improving the working efficiency, the metal block is shaped by the extrusion mode, so that the strength of the metal block is higher than that of the metal block shaped by a mold or cut and shaped in the prior art;

synchronously, the fifth gear 40 interacts with the threaded column 46, the fifth gear 40 rotates to enable the threaded column 46 to move upwards, the threaded column 46 pushes the rotary table 45 to move upwards, at the moment, the first blocking piece 42 is located in the limiting hole 41, the rotary table 45 pushes the first blocking piece 42 to enable the fourth column 43 and the sixth column 54 to move upwards, the top end of the cutter bit 53 abuts against the bottom surface of the cylinder of the bolt, the third spring 55 is compressed, so that the pushing force is applied to the cutter bit 53, the extrusion is stopped after the extrusion plate 27 extrudes the metal block to enable the metal block to deform to a certain degree, and at the moment, the extrusion plate 27 plays a role in clamping the metal block so as to conveniently perform threading on the cylinder of the bolt in the subsequent step;

starting the air cylinder 31, wherein the extending end of the air cylinder 31 pushes the second rod 6 to move, after the second rack 9 at the bottom of the second rod 6 is contacted with the second gear 7, the second gear 7 rotates anticlockwise according to the position shown in fig. 2, so that the third column 34 and the fifth rod 12 rotate anticlockwise, the sliding column 13 moves upwards from the lower part of the seventh rod 30, after the sliding column is contacted with the rotating plate 35, the seventh rod 30 and the sliding rod 3 are pushed to move upwards, the first spring 4 is compressed, after the sliding column 13 is separated from the rotating plate 35, the first spring 4 elastically returns to push the seventh rod 30 to move downwards, and the knocking plate 28 hits the surface of the metal block, so that the purpose of knocking the surface of the metal block to make the surface of the metal block flat and making the internal structure of the metal block compact in the annealing process is achieved, and the strength of the metal block is enhanced;

when the sliding column 13 is contacted with the rotating plate 35 again, the motion state of the knocking plate 28 is the same as that of the above steps, so that the purpose of knocking the metal block for multiple times is achieved, after the tail end of the second rack 9 is driven away from the second gear 7, the knocking plate 28 stops moving, one end of the second rod 6 is contacted with one side of the fourth rod 10 and pushes one end of the fourth rod 10 to rotate, the fourth rod 10 rotates, the other side of the fourth rod 10 and the sixth rod 14 slide relatively, the fourth rod 10 pushes the sixth rod 14 to move in the rotating process, the sixth rod 14 pushes the connecting column 18 to move, so that the piston extrudes cooling liquid in the sleeve 20, the cooling liquid is sprayed onto the bolt from the guide pipe 36, and the purpose of quenching threads and rapidly cooling and shaping the bolt is achieved;

after the bolt is cooled, along with the continuous movement of the second rod 6, the first rack 2 is in contact with the first gear 5, the first gear 5 rotates to drive the second column 29 to rotate, the second column 29 rotates to drive the third gear 37 and the fourth gear 38 to rotate, the fourth gear 38 rotates to drive the second rotary column 44 to rotate, the second rotary column 44 rotates to drive the cutter head 53 to rotate, under the thrust action of the third spring 55, the cutter head 53 circularly moves around the cylinder of the bolt and opens the outer part of the cylinder, so that the purpose of threading the cylinder is achieved, the process is carried out after quenching, so that the cylinder is cooled to ensure that the material of the cylinder is shaped, and in the threading process, the metal cylinder is prevented from being too high in temperature to have strong ductility and cannot be threaded;

after the above steps are completed, the extending end of the cylinder 31 is recovered, the tool bit 53 moves in the direction opposite to the previous direction, and the opened threaded opening is retreated and cleaned, when the second rack 9 contacts the second gear 7, the second gear 7 moves in the direction opposite to the previous direction, at this time, the sliding column 13 moves downwards from above the seventh rod 30, when the sliding column 13 contacts the rotating plate 35, the rotating plate 35 rotates, and the sliding column 13 slides down from the third through groove, so that the purposes of enabling the recovery process of the cylinder 31 to be performed and enabling the subsequent processes to be repeated are achieved;

after the second rod 6 is separated from the fourth rod 10, the second spring 17 is elastically restored, the piston moves in the direction opposite to the previous direction, and at the moment, the cooling liquid in the liquid storage barrel 15 enters the sleeve 20 through the one-way valve, so that the purpose of facilitating the next working procedure is achieved;

after the extension end of cylinder 31 reverted original position, remove stripper plate 27 and make it get back to the original place, each part all goes on according to the step opposite with before, and then can take out the bolt that has processed, and this device can carry out moulding and to the cylinder tapping of bolt to the metal block of bolt in the use, and whole course of working need not to remove the bolt, and is easy and simple to handle swift, has improved work efficiency.
