[0002] A cold heading machine is a specialized piece of equipment primarily used for the mass production of fasteners such as nuts and bolts. The cold heading process involves applying pressure to a metal blank at room temperature, causing it to undergo plastic deformation within a die cavity, shaping it into a specified form and size. In fastener production, the rod-shaped material needs to be reciprocated and sheared to ensure the sheared rod conforms to the forming dimensions. A feeding device is required to supply this material during the operation of the cold heading machine.

[0023] like Figures 1-4 As shown, it illustrates a reciprocating shearing and feeding device for a fastener cold heading forming machine according to an embodiment of the present invention, including a connecting plate 1, and also including a mounting plate 2, an adjusting plate 3, an adjusting pin 4, a plug-in plate 5, a plug-in groove 6, a plug-in block 7, a support wheel 8, a connecting pipe 9, a moving rod 10, a connecting pin 11, an anti-deviation plate 12, and an anti-deviation wheel 13. like Figure 4As shown, mounting plate 2 is installed on the lower surface of connecting plate 1. Mounting plate 2 is fixedly connected to connecting plate 1 by bolts as in the prior art. Adjusting plate 3 is slidably connected inside mounting plate 2. Adjusting pin 4 is threaded through the inner surface of adjusting plate 3 and is slidably connected to mounting plate 2. Square groove is formed on the outer side of mounting plate 2 and is slidably connected to adjusting pin 4. Insertion plate 5 is installed on the inner side of adjusting plate 3. Insertion groove 6 is formed on the upper surface of insertion plate 5. Insertion block 7 is slidably connected in the insertion groove 6 located on the outer side. Support is installed on the upper surface of insertion block 7. Wheel 8, the support wheel 8 can support the bottom of the bar. A connecting pipe 9 is installed on the outer side of the mounting plate 2. A moving rod 10 passes through the connecting pipe 9 and passes through the mounting plate 2. A connecting pin 11 is threaded through the outer surface of the connecting pipe 9. One end of the connecting pin 11, which is threaded into the connecting pipe 9, abuts against the moving rod 10. An anti-deviation plate 12 is installed at the inner end of the moving rod 10. An anti-deviation wheel 13 is installed on the inner side of the anti-deviation plate 12. The anti-deviation wheel 13 can block the front and rear sides of the bar to prevent the bar from deviating during movement.

[0024] like Figure 2 As shown, a first support frame 14 is mounted on the lower surface of the mounting plate 2. A support column 15 is slidably connected inside the first support frame 14. A second support frame 16 is slidably connected to the outer side of the support column 15. A support leg 18 is mounted on the lower surface of the second support frame 16. A buffer spring 17 is installed inside both the first support frame 14 and the second support frame 16. The inner end of the buffer spring 17 is mounted on the outer side of the support column 15. A fixing pin 25 is threaded through the outer side of both the first support frame 14 and the second support frame 16. The fixing pin 25 at the top is threaded into the first support frame 14 and abuts against the support column 15. The fixing pin 25 at the bottom is threaded into the second support frame 16 and abuts against the support column 15.

[0025] like Figure 3 As shown, a crossbeam 19 is installed on the inner side of the second support frame 16. A movable frame 20 is slidably connected to the outer surface of the crossbeam 19. A movable frame 21 is installed on the lower surface of the movable frame 20. A threaded column 22 is installed on the lower surface of the movable frame 21. A threaded tube 23 is threadedly sleeved on the outer surface of the threaded column 22. A contact plate 24 is rotatably connected to the bottom end of the threaded tube 23. There are four sets of contact plates 24. As the threaded tube 23 rotates and moves downward, the contact plate 24 contacts the ground. The threaded column 22 holds the movable frame 20 in place, preventing the movable frame 20 from moving along the crossbeam 19.

[0026] In this embodiment, as Figure 1As shown, a mounting bracket 26 is mounted on the outer side of the mounting plate 2. The mounting bracket 26 is mounted with a mounting plate 28 via a mounting pin 27. A feeding frame 29 is mounted on the inner side of the mounting plate 28. A cold heading machine body 30 is located on the left side of the feeding frame 29. The cold heading machine body 30 is a common fastener cold heading machine on the market. A reciprocating shearing mechanism is set inside the cold heading machine body 30. The reciprocating shearing mechanism consists of a motor, a shearing blade, and a reciprocating connecting rod. The cold heading machine body 30 requires an external power supply. When the cold heading machine body 30 is running, it can move the rod-shaped material. Therefore, the support wheel 8 and the anti-deviation wheel 13 do not need to provide power to the rod-shaped material.

[0027] Working principle: Move the device to the designated location, loosen the fixing pin 25 counterclockwise to allow the buffer spring 17 to rebound, pushing the support column 15 to extend along the inside of the first support frame 14 and the second support frame 16, so that the support leg 18 contacts the ground. Operate the moving frame 20 to move outward along the crossbeam 19. The outward movement of the moving frame 20 drives the moving frame 21 to move outward. The outward movement of the moving frame 21 drives the threaded column 22 to move outward. The outward movement of the threaded column 22 drives the threaded tube 23 to move outward. The outward movement of the threaded tube 23 drives the contact plate 24 to move outward. After the device is in place, rotate the threaded tube 23 clockwise, so that the threaded tube 23 moves downward along the threaded column 22. The downward movement of the threaded tube 23 drives the contact plate 24 to move downward. The downward movement of the contact plate 24 contacts the ground, supporting the crossbeam 19. At this time, the left side of the mounting plate 2 contacts the right side of the feed frame 29, the left side of the mounting bracket 26 is close to the mounting piece 28, the mounting pin 27 is inserted into the mounting piece 28 through the mounting bracket 26, and then the mounting pin 27 is rotated clockwise to fix the mounting bracket 26. The rod is inserted into the body 30 of the cold heading machine by passing through the inner side of the mounting plate 2 and the feeding frame 29. The connecting pin 11 is loosened counterclockwise, and the moving rod 10 is moved inward along the connecting pipe 9. The moving rod 10 moves inward, which drives the anti-deviation plate 12 to move inward. The anti-deviation plate 12 moves inward, which drives the anti-deviation wheel 13 to move inward. The anti-deviation wheel 13 moves inward and contacts the rod. Then the connecting pin 11 is rotated clockwise to press against the moving rod 10. Manipulate the support wheel 8 to slide the plug block 7 into the plug slot 6 located on the outside. Loosen the adjusting pin 4 counterclockwise. Manipulate the adjusting plate 3 to move upward along the mounting plate 2. The upward movement of the adjusting plate 3 drives the plug plate 5 to move upward. The upward movement of the plug plate 5 drives the plug block 7 to move upward. The upward movement of the plug block 7 drives the support wheel 8 to move upward. The support wheel 8 moves upward and contacts the rod. After adjustment, rotate the adjusting pin 4 clockwise to fix the adjusting plate 3. When the cold heading forming machine body 30 is running, the bar stock moves to the left along the support wheel 8 and the anti-deviation wheel 13, causing the support wheel 8 and the anti-deviation wheel 13 to roll along the surface of the bar stock. The bar stock eventually enters the interior of the cold heading forming machine body 30 along the feed frame 29 for fastener processing. The formed fastener is cut off by the reciprocating shearing mechanism for subsequent processing.
