[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in 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 creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a high-performance non-linear buffer, including a main body 10, a first hole 101, an annular groove 102, a baked paint 20, and a second hole 201;

[0031] The performance of the overall buffer is improved, and the specific implementation manner is as follows:

[0032] The overall main body 10 is arranged in a cylindrical structure, and a baked paint 20 is fixedly arranged on one side surface of the main body 10. A buffer mechanism is arranged inside the main body 10, and the buffer mechanism includes: a first hole 101 penetrates through the inside of the main body 10, an annular groove 102 is embedded on the surface of the main body 10, a second hole 201 penetrates through the inside of the baked paint 20, one end surface of the main body 10 is arranged in a chamfered structure, and the surface of the main body 10 and the baked paint 20 are respectively arranged at both ends of the main body 10. Characters are embedded on the surface of the main body 10, and the characters of the main body 10 are arranged around the outside of the first hole 101. The characters of the main body 10 and the baked paint 20 are respectively arranged at both ends of the main body 10. The annular groove 102 is arranged at the end of the main body 10, and the annular groove 102 is close to the side of the main body 10 where the baked paint 20 is located. The diameter of the second hole 201 is smaller than the diameter of the first hole 101. The second hole 201 and the first hole 101 are arranged in a penetrating manner, and the center points of the first hole 101 and the second hole 201 are correspondingly arranged.

[0033] The materials inside the main body 10 include PPDI, polyether polyurethane prepolymer materials, chain extenders, foaming agents, catalysts, anti-yellowing agents, etc. The PPDI and polyether polyurethane prepolymer materials are pre-dried at 50 °C for 6 hours. After pre-drying, the PPDI and polyether polyurethane prepolymer materials are sucked into the inner part of the A kettle of the low-pressure casting machine. Then, the temperature is raised through the A kettle of the low-pressure casting machine until it reaches 70 °C. The chain extender, foaming agent, catalyst, anti-yellowing agent and other materials are respectively added into the inner part of the B kettle of the low-pressure casting machine, and dehydration operation is carried out on the chain extender. At this time, the casting machine verifies the chain extension formula of the material. After the inspection is completed, automatic casting is carried out. The mold is moved to the casting position, and the casting machine performs automatic casting to pour the internal materials into the mold. When the polyether polyurethane prepolymer material enters the mold, it foams and forms in 12 - 15 minutes. After the polyether polyurethane prepolymer material is formed, the formed product is taken out from the mold, and the product is placed in the oven. The oven dries the product at 40 °C for 16 hours to carry out the curing operation on the product.

[0034] Then, a character is engraved on one end of the product through a lettering machine, with the height of the character being 4 mm and the depth being 0.3 mm. The product is polished by a grinding machine to form a chamfer on one side of the product, and at the same time, the burrs on the surface of the product are removed. Then, the baking paint 20 is fixed on the surface of the product to form the main body 10.

[0035] Working principle: When using this high-performance non-linear buffer, the main body 10 is set, and the materials inside the buffer are replaced, which improves the overall performance and increases the overall practicality.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
