[0002] A cold heading machine is a type of metalworking equipment that forms raw materials into the desired shape without undergoing any modification (primarily softening or hardening, etc.). It is primarily used to produce a variety of standard fasteners and other metal products. The cold heading machine operates by applying pressure to the metal blank at room temperature, causing it to plastically deform within a die cavity, thereby forming it into the required shape and dimensions. This processing method is suitable for mass production due to its high production efficiency, cost-effectiveness, and environmental friendliness. Cold heading machines can process fasteners such as bolts, screws, rivets, and nuts, and are also used to produce fasteners for automotive parts, construction materials, machinery components, the power industry, and other industries. This type of equipment typically includes multiple workstations, enabling automated production and improving production efficiency and product quality.
[0003] However, the cold heading machine still has certain defects during use. The existing cold heading machine needs to be processed through a feeding mechanism. However, the roller rod on the feeding mechanism that transmits and feeds the processed original parts needs to be cleaned on its outer surface after being used a certain number of times to extend the life of the equipment. However, the existing feeding roller rod needs to be disassembled by releasing the thread lock during the cleaning process. This method is relatively cumbersome and difficult to clean and replace. For this reason, a feeding mechanism for a cold heading machine is proposed, which solves the above problems of difficult cleaning and difficult replacement by quickly disassembling the roller rod.

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Refer to the instruction manual Figure 1-4 , including a feeding mechanism body 1, a feeding transmission rod 2 is provided on the inner side of the feeding mechanism body 1, one end of the feeding transmission rod 2 is fixedly connected to the connecting rod 3, a feeding roller rod 4 is provided on one side of the feeding transmission rod 2, an inserting groove 5 is provided inside the feeding roller rod 4, the feeding roller rod 4 is inserted into the outside of the connecting rod 3 through the inserting groove 5, an embedded groove 6 is provided inside the connecting rod 3, a movable plate 7 is provided inside the embedded groove 6, a first movable groove 8 is provided on the movable plate 7, a sliding rod 9 is slidably connected to the first movable groove 8, and the sliding rod 9 is fixedly connected to the embedded groove 6, a second movable groove 10 is provided on the outer wall of the connecting rod 3, a limiting rod 11 is inserted into the second movable groove 10, one end of the limiting rod 11 is fixedly connected to the movable plate 7, and a limiting groove 1 is provided on the inner wall of the embedding groove 5 2. After the feed roller rod 4 has been running for a period of time, the surface of the feed roller rod 4 needs to be cleaned and replaced regularly due to wear. At this time, the movable plate 7 can be moved inward so that the movable plate 7 can slide on the slide rod 9 using the first movable groove 8, thereby making the limit rod 11 move on the second movable groove 10. However, when the limit rod 11 is completely disengaged from the limit groove 12, the limit rod 11 will release the limiting effect of the limit groove 12. At this time, the connecting rod 3 and the feed roller rod 4 are completely released from the limiting effect through this effect, thereby achieving the effect of quick disassembly of the feed roller rod 4. After the feed roller rod 4 is completely disengaged, the surface of the feed roller rod 4 can be cleaned and repaired separately, which greatly reduces the difficulty of cleaning and maintenance, and further extends the service life of the equipment.
[0022] Then, one end of the slide rod 9 is fixedly connected to the auxiliary plate 13, and an external support spring 14 is wound around the outer wall of the slide rod 9. One end of the external support spring 14 is fixedly connected to the movable plate 7, and the other end of the external support spring 14 is fixedly connected to the auxiliary plate 13; through the above structure and utilizing the elastic properties of the external support spring 14, when the feed roller rod 4 is clamped and fixed to the outer wall of the connecting rod 3, the movable plate 7 is blessed with a reset effect, and the limiting rod 11 clamps and fixes the limiting groove 12, thereby ensuring the stability of the feed roller rod 4 and the connecting rod 3 in a fixed state.
[0023] Then, the movable plate 7 and the limiting rod 11 are arranged in a symmetrical manner inside the embedded groove 6, and the movable plate 7 is mounted on the sliding rod 9 through the first movable groove 8; through this structure, two sets of limiting rods 11 are provided to limit the limiting groove 12 at the same time, thereby ensuring the stability of the equipment in a fixed state.
[0024] Next, the movable plate 7 is fixedly connected to the extrusion pad 15 through the embedded groove 6, and the outer wall of the extrusion pad 15 is provided with anti-slip grooves; by pressing the extrusion pad 15, the movable plate 7 can be easily moved on the slide rod 9, and the setting of the extrusion pad 15 can reduce the probability of slipping.
[0025] At this time, the limiting rod 11 and the second movable groove 10 fit together, and the limiting rod 11 passes through the second movable groove 10 and is inserted into the limiting groove 12; this structure makes the limiting rod 11 more stable during the movement, and the tightness between the limiting rod 11 and the second movable groove 10 is improved in the fixed state.
[0026] Next, a roller pad 16 is bonded to the outside of the feed roller 4, and the roller pad 16 is arranged in a C shape. Through this structure, the roller pad 16 can effectively protect the outside of the feed roller 4, reduce wear and tear, and extend the service life.
