When the formed bolt is discharged, it will first impact the buffer plate, causing the buffer plate to rotate and compress the spring. Under the restoring action of the spring, the buffer plate will be forced to return to its original position. By extending the length of the discharging pipe and buffering the bolt during discharging, the damage caused by excessive impact force during bolt discharging is prevented.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0029] As Figures 1 to 8 shown, the present invention provides a bolt cold heading machine, including an equipment main body 1.

The number of the connecting rods 11 is two. The other ends of the two connecting rods 11 are respectively hinged with the two connecting plates 7.

[0030] When the driving motor 8 is started, it will cause the driving shaft 9 to drive the rotary rod 10 to rotate. Since both ends of the connecting rod 11 are hinged to the rotary rod 10 and the connecting plate 7 respectively, one end of the connecting rod 11 will rotate together with the rotary rod 10, so that the other end of the connecting rod 11 will generate a thrust on the connecting plate 7, pushing the two connecting plates 7 to drive the first mounting block 3 and the second mounting block 5 to move away from each other, and further causing the first guide wheel 4 and the second guide wheel 6 that are movably sleeved inside the first mounting block 3 and the second mounting block 5 to move together. In this way, the adjustment of the distance between the first guide wheel 4 and the second guide wheel 6 can be realized, thereby improving the convenience of adjusting the distance between the first guide wheel 4 and the second guide wheel 6.

[0038] As a technical optimization scheme of the present utility model, due to the restoring action of the spring 19, the buffer plate 18 will rotate and then return to its original position, thereby buffering the discharging of the cold heading machine by means of the fixing plate 17 and the buffer plate 18.

[0039] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 8 On the left side of the top of the equipment main body 1, a power motor 20 is fixedly installed, and the other end of the output shaft of the power motor 20 is fixedly sleeved with a threaded rod 21.

[0040] As a technical optimization scheme of the present utility model, when the power motor 20 is started, the threaded rod 21 will rotate.

[0041] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 8 A movable block 22 is threadedly sleeved on the top of the outer surface of the threaded rod 21. The right end of the movable block 22 is movably connected to the left end of the equipment main body 1. The left end of the movable block 22 is hinged with an inclined rod 23, and the other end of the inclined rod 23 is hinged to the left side of the top of the extension tube 16.

[0042] As a technical optimization scheme of the present utility model, when the threaded rod 21 rotates, the movable block 22 will drive one end of the inclined rod 23 to move, so that the other end of the inclined rod 23 generates a thrust on the extension tube 16, pushing the extension tube 16 to move.

[0043] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 In the front of the middle part of the top of the equipment main body 1, a controller 24 is fixedly installed, and on the right side of the front end of the equipment main body 1, an observation window 25 is fixedly sleeved.

There are four universal wheels 27 and they are symmetrical with each other about the center of the bottom plate 26.

[0046] As a technical optimization solution of the present invention, the presence of the universal wheel 27 makes it easier to move the cold heading machine.

[0047] refer to Figure 2 and Figure 4 The first mounting block 3 and the second mounting block 5 have the same shape and size, and the first guide wheel 4 and the second guide wheel 6 have the same shape and size and are located on the same plane.

[0048] As a technical optimization solution of the present invention, since the first guide wheel 4 and the second guide wheel 6 have the same shape and size and are located on the same plane, the stability of the movement of the cold heading steel wire can be ensured.

[0049] The working principle and use process of this utility model:

[0050] First, the operator starts the drive motor 8 according to the specifications of the cold-headed steel wire to be processed, so that the drive shaft 9 drives the rotating rod 10 and one end of the connecting rod 11 to rotate, so that the other end of the connecting rod 11 generates a thrust on the connecting plate 7, pushing the two connecting plates 7 to move oppositely with the first mounting block 3 and the second mounting block 5 along the outer surface of the limit plate 12. At this time, the first guide wheel 4 and the second guide wheel 6 that are movably sleeved inside the first mounting block 3 and the second mounting block 5 will move together, so that the distance between the first guide wheel 4 and the second guide wheel 6 can be adjusted, thereby improving the convenience of adjusting the distance between the first guide wheel 4 and the second guide wheel 6, and the cold-headed steel wire processed by the cold heading machine will be formed into bolts and output from the discharge pipe 14.

[0051] When the formed bolts are output from the discharge pipe 14, the operator starts the power motor 20 according to the height of the collection box, causing the threaded rod 21 to rotate. As a result, the movable block 22 threadedly sleeved on the threaded rod 21 drives the top of the inclined rod 23 to move downward, and then the bottom end of the inclined rod 23 generates a thrust on the extension pipe 16, pushing the extension pipe 16 to move along the outer surface of the discharge pipe 14. At the same time, when the bolts are output from the discharge pipe 14, they will first impact the buffer plate 18. At this time, the buffer plate 18 will rotate and compress the spring 19. Under the restoring action of the spring 19, the buffer plate 18 will be forced to return to its original position. The operator can shorten the height difference between the bolts and the collection box by extending the length of the discharge pipe 14. The mutual cooperation of the buffer plate 18 and the spring 19 can play a buffering role when the bolts are discharged. With the mutual cooperation of each mechanism, it is possible to prevent the bolts from being knocked and damaged due to excessive impact force during discharge.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
