Description

Technical Field

[0001] This utility model relates to the field of round bars, and more particularly to a high-strength stainless steel round bar. Background Technology

[0002] In traditional applications of solid stainless steel round bars, the axial pressure is usually borne solely by the properties of the material itself. Due to its relatively simple structure, when faced with high-load mechanical transmission or as a structural support component, stress tends to concentrate in certain specific areas under bending and torsional forces, causing the round bar to easily experience local deformation or even breakage.

[0003] For example, in applications such as drive shafts of large machinery and support columns of complex structures, ordinary solid round bars are difficult to withstand frequent changes in bending and torsional forces for a long time, and equipment failures caused by deformation occur frequently, affecting the normal operation and service life of the entire equipment. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength stainless steel round bar to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-strength stainless steel round bar includes: a stainless steel bar body, with grooves and through holes respectively formed on the outer periphery of the stainless steel bar body, the grooves being filled with composite material, and a rectangular groove formed at the axial center of the stainless steel bar body, with a rectangular steel bar inserted into the inner side of the rectangular groove.

[0007] The stainless steel bar body, serving as the main structure, provides fundamental strength and stability. The design of the corrugated grooves and circumferential array of through holes increases the surface area and heat dissipation of the bar, helping to maintain lower temperatures in high-load, high-pressure working environments, thereby improving the bar's durability and service life. Secondly, the composite material filling the corrugated grooves further enhances the bar's mechanical properties. Composite materials such as titanium alloys or epoxy resins possess good strength and toughness, enabling them to bond tightly with the stainless steel bar body, forming a more robust overall structure. Finally, the rectangular steel bars inserted into the rectangular grooves are fixed by casting a liquid phase, forming a tight connection with the stainless steel bar body. The high strength and toughness of the rectangular steel significantly improve the bar's load-bearing capacity, allowing it to maintain stable performance in various harsh working environments.

[0008] Preferably, the groove is formed in a wavy structure.

[0009] Preferably, the through holes are arranged in a circumferential array and are circular in shape.

[0010] Preferably, the specific material of the composite material is titanium alloy or epoxy resin.

[0011] Preferably, the inner wall of the rectangular groove is in close contact with the rectangular steel.

[0012] Preferably, the rectangular groove and the rectangular steel are fixed by casting a liquid phase.

[0013] Preferably, the rectangular steel is made of carbon steel or alloy steel.

[0014] Compared with the prior art, this utility model provides a high-strength stainless steel round bar, which has the following beneficial effects:

[0015] 1. This utility model significantly improves the mechanical properties of round bars through the wavy groove structure on the periphery of the stainless steel bar body. It changes the traditional shape, making the force distribution more uniform when the round bar is subjected to bending and torsional forces. Compared with solid round bars, it can disperse stress concentration points, enhance bending and torsional resistance, and help maintain shape stability in high-load mechanical transmission and structural support scenarios, reducing equipment failure. The composite materials such as titanium alloy or epoxy resin filled in the wavy groove further enhance this advantage. Titanium alloy has high strength and low density characteristics, and epoxy resin has good adhesion and toughness. They work together with the stainless steel bar body to exert their advantages under different stress conditions. For example, in dynamic mechanical movement, they can buffer impact forces and reduce the stress burden on the body, ultimately effectively improving the overall mechanical properties of the round bar.

[0016] 2. The rectangular groove located at the axial center of the stainless steel bar and the inserted rectangular steel member significantly contribute to the bar's load-bearing capacity. Made of carbon steel or alloy steel, the rectangular steel member's high strength and good toughness provide strong core support for the bar. When the bar is subjected to axial pressure, the rectangular steel member effectively distributes the pressure, preventing localized deformation or damage, thus enhancing safety and reliability. Simultaneously, the multiple circular through-holes arranged in a circumferential array greatly increase the bar's surface area. During operation, heat can be dissipated more quickly through these through-holes. Attached Figure Description

[0028] The stainless steel bar body 1 serves as the main structure, providing fundamental strength and stability. The design of the corrugated grooves 2 and the circumferential array of through holes 6 increases the surface area and heat dissipation performance of the bar, helping to maintain a lower temperature in high-load, high-pressure working environments, thereby improving the bar's durability and service life. Secondly, the composite material 3 filled within the corrugated grooves 2 further enhances the bar's mechanical properties. Composite materials 3, such as titanium alloy or epoxy resin, possess good strength and toughness, enabling them to bond tightly with the stainless steel bar body 1, forming a more robust overall structure. Finally, the rectangular steel bars 5 inserted into the rectangular grooves 4 are fixed by casting a liquid phase, forming a tight connection with the stainless steel bar body 1. The high strength and toughness of the rectangular steel bars 5 significantly improve the bar's load-bearing capacity, allowing it to maintain stable performance in various harsh working environments.

The wavy groove 2 is filled with composite materials such as titanium alloy or epoxy resin 3. These materials possess good strength and toughness, further enhancing the mechanical properties of the round bar.

[0037] Multiple circular through holes 6 are also arranged in a circumferential array on the round bar. These through holes 6 help to further increase the surface area of ​​the round bar, improve heat dissipation efficiency, and reduce the overall weight of the round bar, making it lighter and more flexible.
