[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-4 This utility model provides a technical solution: an electric hammer fastener cold heading machine. This application mainly addresses the problem that fasteners processed by cold heading machines often have a large amount of oil adhering to their surface, requiring manual cleaning afterward, which is time-consuming, labor-intensive, and inefficient. The specific solution is as follows: It includes a workbench 1, which can be fixed to the ground with screws. On the left and right sides of the workbench 1, there are opposing die assemblies 7 and pushing assemblies 3. The pushing assembly 3 provides pushing force to the cold heading punch, while the die assembly 7 has a cold heading die for engaging with the cold heading punch. A cutting assembly 4 is provided on the corresponding side of the die assembly 7, which can cut the prepared material for processing.

[0022] Please see Figure 1 A collection trough 2 is provided in the middle of the workbench 1, and a stop door 5 is provided on the left side of the collection trough 2. The stop door 5 is hinged to the workbench 1. The stop door 5 is provided to facilitate the removal of fasteners inside the collection trough 2.

[0023] Furthermore, a rotating shaft 66 is provided inside the collection tank 2, and an oil-absorbing plate 69 is provided in a ring shape in the middle of the rotating shaft 66. The oil-absorbing plate 69 is located inside the collection tank 2, and the end face of the oil-absorbing plate 69 is wavy. After the rotating shaft 66 rotates, the oil-absorbing plate 69 can rotate with the rotating shaft 66, thereby adsorbing the oil on the fasteners that enter the collection tank 2. No manual operation is required, and the degree of automation is high.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The pushing assembly 3 includes an electric telescopic rod 31, a fixed sleeve 32, and a connecting rod 321. The connecting rod 321 is inserted into the fixed sleeve 32. The electric telescopic rod 31 is located between adjacent fixed sleeves 32. A push plate 33 is fixedly installed at the ends of the electric telescopic rod 31 and the connecting rod 321. A punch is provided on the end face of the push plate 33 corresponding to the die assembly 7. A return spring 322 is provided inside the fixed sleeve 32 and is movably inserted into the connecting rod 321. The return spring 322 can reduce over-forging caused by excessive instantaneous punching force of the punch.

[0025] Please see Figure 3 and Figure 4Below the pushing component 3 is a linkage component 6, which includes a first transmission rod 60 and a second transmission rod 61. The first transmission rod 60 and the second transmission rod 61 are connected by a transmission belt. On opposite sides of the first transmission rod 60 and the second transmission rod 61 are pulleys for engaging with the transmission belt. Through the transmission belt and pulleys, the rotational force of the first transmission rod 60 can be transmitted to the second transmission rod 61, causing the second transmission rod 61 to rotate. The first transmission rod 60, the second transmission rod 61, and the rotating shaft 66 are parallel to each other, and the rotating shaft 66 is located below the first transmission rod 60 and the second transmission rod 61. A second gear 67 is fixedly installed at the front end of the first transmission rod 60, and a second rack 68 is meshed below the second gear 67. The second rack 68 is fixedly installed on the push plate 33. A sector gear 63 is fixedly installed at the front end of the second transmission rod 61, and a sliding seat 62 is provided on the outside of the sector gear 63. A first rack 64 is fixedly installed on the sliding seat 62. A gear 65 is fixedly installed at the front end of the rotating shaft 66. The gear 65 meshes with a rack 64, and the rack 64 is located above the gear 65.

[0026] Working principle: In this electric hammer fastener cold heading machine, when the electric telescopic rod 31 drives the push plate 33 to perform cold heading operation on the fastener, the push plate 33 can cause the rack 68 to produce the same movement. Through the meshing of the rack 68 and the gear 67, the transmission rod 60 rotates. Through the connection of the transmission belt, the rotation of the transmission rod 60 can cause the transmission rod 61 to rotate in the same way, which in turn causes the sector gear 63 to rotate. Through the meshing of the sector gear 63 and the sliding seat 62, the sliding seat 62 can drive the rack 64 to produce reciprocating motion. Through the meshing of the gear 65 and the rack 64, the rotating shaft 66 can rotate. Through the rotation of the rotating shaft 66, the oil suction plate 69, which is distributed in a ring on the outside of the rotating shaft 66, can rotate inside the collection tank 2, which removes oil from the fasteners that enter the collection tank 2, further reducing the oil on the surface of the fasteners after cold heading.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
