Description

Technical Field

[0001] This utility model belongs to the technical field of livestock breeding equipment accessories, and in particular relates to a precision forging for livestock breeding. Background Technology

[0002] In livestock farming, a large number of farming equipment are required, such as fence connectors, feed trough supports, and waterer fixtures. The core load-bearing components of these devices are mostly made of forgings. Forgings, with their dense internal structure and excellent mechanical properties, can meet the requirements of load-bearing capacity, wear resistance, and corrosion resistance of farming equipment during long-term use.

[0003] However, existing forgings for livestock farming have the following shortcomings: First, they lack precision. The large dimensional tolerances of the forgings result in low fitting accuracy during assembly, making them prone to loosening, which affects the stability of the farming equipment and increases the risk of equipment failure. Second, they have poor corrosion resistance. The livestock farming environment contains a large amount of water vapor and corrosive substances produced by the fermentation of manure. Forgings exposed to this environment for a long time are prone to rust, shortening their service life and increasing farming costs.

[0004] Therefore, it is necessary to design a precision forging for livestock breeding. Utility Model Content

The outer surface of the forging body is sequentially coated with a sandblasting and rust-removing layer, a zinc-nickel alloy plating layer, and a polytetrafluoroethylene coating. One end of the forging body has a connecting portion with a precision threaded hole at its center. The inner wall of the threaded hole is coated with a wear-resistant coating. A positioning platform is provided on the outer periphery of the connecting portion, and a sealing groove is provided on the end face of the positioning platform. A rubber sealing ring is fitted into the sealing groove. The other end of the forging body has a functional portion with a hollowed-out groove on its side for weight reduction.

[0020] Example 1 A preferred embodiment of the precision forging for livestock breeding provided by this utility model is as follows: Figures 1 to 4 As shown: A precision forging for livestock breeding includes a forging body 1, which is precision forged from 42CrMo alloy steel using a hot die forging process. After forging, it undergoes quenching and tempering treatment to ensure its mechanical properties. The outer surface of the forging body 1 is sequentially provided with a sandblasting and rust removal layer 12, a zinc-nickel alloy plating layer 13, and a polytetrafluoroethylene coating 14. The sandblasting and rust removal layer 12 is used to remove oxide scale and rust from the surface of the forging, improving the adhesion of subsequent coatings. The zinc-nickel alloy plating layer 13 is prepared by an electrodeposition process, with a thickness controlled at 10μm, exhibiting excellent corrosion resistance. The polytetrafluoroethylene coating 14 is prepared by a spraying process, with a thickness of 4μm, further enhancing corrosion resistance and wear resistance.

[0021] One end of the forging body 1 is provided with a connecting part 8, and a precision threaded hole 6 is opened in the center of the connecting part 8. The tolerance grade of the precision threaded hole 6 is 6H, and the thread surface is ground and the roughness Ra is controlled at 0.6μm. The inner wall of the threaded hole 6 is provided with a ceramic-based composite wear-resistant coating 15. The wear-resistant coating 15 is prepared by plasma spraying process, the coating thickness is 60μm, and the material is composite ceramic to improve the wear resistance of the inner wall of the threaded hole 6. The outer circumference of the connecting part 8 is integrally formed with a positioning platform 7. The end face of the positioning platform 7 is provided with a sealing groove 9. A rubber sealing ring 11 is adapted to be installed in the sealing groove 10. The rubber sealing ring 11 is made of aging-resistant nitrile rubber material to enhance the sealing of the connection part.

[0022] The other end of the forging body 1 is provided with a functional part 2. Three mounting ears 3 are integrally formed on the functional part 2. The three mounting ears 3 are evenly distributed along the circumference of the functional part 2. Mounting holes 4 are opened on the mounting ears 3. The mounting holes 4 are smooth holes with the inner wall being reamed to facilitate the insertion of bolts to fix the forging. The side of the functional part 2 is provided with two hollow grooves 5 for weight reduction. The two hollow grooves 5 and the three mounting ears 3 are alternately distributed. The inner wall of the hollow grooves 5 is rounded with a radius of 2mm to avoid stress concentration. A reinforcing rib 9 is provided in the middle of the forging body 1. The reinforcing rib 9 is distributed along the length of the forging body 1. The reinforcing rib 9 is integrally forged with the forging body 1. The cross section of the reinforcing rib 9 is an isosceles triangle. The height of the reinforcing rib 9 is half the diameter of the forging body 1, which effectively improves the bending resistance of the forging body 1.

[0023] In this embodiment, the forging is quickly positioned using the positioning table 7 during assembly and use. The precision threaded hole 6 forms a high-precision fit with the connecting part, and the rubber sealing ring 11 ensures the sealing of the connection. The mounting hole 4 on the mounting ear 3 is used to fix the forging in the corresponding position of the breeding equipment. The reinforcing rib 9 improves the overall load-bearing capacity of the forging, and the hollow groove 5 reduces weight while avoiding stress concentration. In the livestock breeding environment, the synergistic effect of the zinc-nickel alloy plating 13 and the polytetrafluoroethylene coating 14 can effectively resist the erosion of moisture and corrosive substances, and the wear-resistant coating 15 on the inner wall of the threaded hole 6 extends the service life of the threaded connection.
