Description

Technical Field

[0001] The utility model relates to the technical field of carbon spring steel wires, in particular to a reinforced high-quality carbon spring steel wire. Background Art

[0002] Carbon spring steel wire is a kind of steel specially used for making springs. It is made by hot-rolling high-quality carbon steel into wire rods and then cold-drawing it into round steel wire. The main alloying element of this steel wire is carbon, and it may also contain an appropriate amount of manganese and other elements to improve the toughness and plasticity of the material and ensure that it has excellent elastic recovery performance after deformation. It is widely used in Simmons beds, automobiles and various cushions, machinery manufacturing, stationery and power tools, torsion springs, tension springs, electrical equipment and other industries.

[0003] The structure of the existing carbon spring steel wire is relatively simple, which makes the strength of the carbon spring steel wire low. As a result, during the use of the carbon spring steel wire, due to repeated compression, the carbon spring steel wire is repeatedly deformed, which easily causes fatigue of the carbon spring steel wire, and thus easily causes the carbon spring steel wire to break, making the carbon spring steel wire unusable. In addition, due to the repeated deformation of the spring, the temperature of the spring steel wire increases, thereby reducing the elasticity of the spring steel wire, affecting the supporting stability of the spring, and reducing the service life of the carbon spring steel wire. Therefore, a reinforced high-quality carbon spring steel wire is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a reinforced high-quality carbon spring steel wire, which has the advantages of fatigue resistance and high temperature resistance, and solves the problem in the prior art that carbon spring steel is prone to high temperature during repeated deformation, resulting in reduced structural strength of carbon spring steel and affecting support stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforced high-quality carbon spring steel wire, comprising a carbon spring steel wire body, a wear-resistant layer is provided at the outer end of the carbon spring steel wire body, and a first reinforcing rib and a second reinforcing rib are provided between the wear-resistant layer and the carbon spring steel wire body;

[0006] The first reinforcing ribs and the second reinforcing ribs are spirally wound on the outer end surface of the carbon spring steel wire body, and the first reinforcing ribs and the second reinforcing ribs are alternately arranged in a circular array on the outer side of the carbon spring steel wire body, and a positioning strip is arranged on the inner end surface of the wear-resistant layer.

[0007] As a preferred reinforced high-quality carbon spring steel wire of the utility model, the first reinforcing rib is made of carbon fiber, and the first reinforcing rib is a cylindrical structure.

[0008] As a preferred reinforced high-quality carbon spring steel wire of the utility model, the second reinforcing rib is made of nylon material, and the cross-section of the second reinforcing rib is an elliptical structure.

[0009] As a preferred embodiment of the reinforced high-quality carbon spring steel wire of the utility model, the wear-resistant layer is made of polytetrafluoroethylene.

[0010] As a preferred reinforced high-quality carbon spring steel wire of the utility model, the positioning strip is a spiral structure, the cross-section of the positioning strip is an "M"-shaped structure, the first reinforcing rib is stuck in the groove on the surface of the positioning strip, and the second reinforcing rib is alternately arranged with the positioning strip.

[0011] As a preferred embodiment of the reinforced high-quality carbon spring steel wire of the utility model, the side of the positioning strip is provided with an exhaust hole.

[0012] As a preferred reinforced high-quality carbon spring steel wire of the utility model, the surface of the carbon spring steel wire body is provided with an anti-oxidation coating.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model enhances the structural strength of the spring steel wire by adding a first reinforcing rib and a second reinforcing rib between the wear-resistant layer and the carbon spring steel wire body, thereby reducing the deformation of the spring steel wire and reducing the probability of thermal fatigue of the spring steel wire. The first reinforcing rib and the second reinforcing rib made of nylon and carbon fiber enable the spring steel wire to still provide stable support after the thermal decay of the carbon spring steel wire body in the center, thereby ensuring the stability of the spring. The first reinforcing rib and the second reinforcing rib are constrained in conjunction with the positioning strip structure, so that the spring steel wire can exert force evenly and stably, thereby improving the stability of the spring steel wire.

[0015] 2. The utility model provides exhaust holes on the side of the positioning strip so that the positioning strip undergoes elastic deformation under the extrusion of the first positioning strip, thereby frequently using the exhaust holes for gas exchange, thereby enhancing the air flow rate on the surface of the carbon spring steel wire body, reducing the probability of thermal fatigue performance attenuation, and improving the stability and service life of the spring steel wire body.

[0021] See also Figure 1-Figure 4 A reinforced high-quality carbon spring steel wire comprises a carbon spring steel wire body 1, a wear-resistant layer 4 is arranged at the outer end of the carbon spring steel wire body 1, and a first reinforcing rib 2 and a second reinforcing rib 3 are arranged between the wear-resistant layer 4 and the carbon spring steel wire body 1;

[0022] The first reinforcing ribs 2 and the second reinforcing ribs 3 are spirally wound on the outer end surface of the carbon spring steel wire body 1 , and the first reinforcing ribs 2 and the second reinforcing ribs 3 are alternately arranged in a circular array on the outer side of the carbon spring steel wire body 1 , and a positioning strip 401 is provided on the inner end surface of the wear-resistant layer 4 .

[0023] After the carbon spring steel wire is made into a spring, since the surface of the carbon spring steel wire body 1 is provided with a spirally wound first reinforcing rib 2 and a second reinforcing rib 3, the carbon fiber has extremely high specific strength and specific modulus, which means that without significantly increasing the mass, it can provide additional bearing capacity and tensile strength, so that the spring can withstand higher loads, improve the overall stiffness of the spring, and reduce the deformation of the spring when it is compressed or stretched. The spiral winding can disperse the stress concentration point, which helps to extend the service life of the spring, especially under repeated loads. By arranging the exhaust hole 402 on the side of the positioning bar 401, the positioning bar 401 is elastically deformed under the extrusion of the first positioning bar 401, so that the exhaust hole 402 is frequently used for gas exchange, thereby enhancing the air flow rate on the surface of the carbon spring steel wire body 1, thereby improving the heat dissipation efficiency and avoiding metal fatigue, elastic loss or structural deformation caused by overheating.

[0024] Furthermore, the first reinforcing rib 2 is made of carbon fiber, and the first reinforcing rib 2 is a cylindrical structure.

[0025] By having extremely high rigidity and elasticity, and in a high temperature environment, the carbon fiber can also maintain high temperature stability. When the carbon spring steel wire body 1 is thermally fatigued, the carbon fiber can also provide stable support, which greatly improves the stability of the carbon spring steel wire.

[0026] Furthermore, the second reinforcing rib 3 is made of nylon, and the cross section of the second reinforcing rib 3 is an elliptical structure.

[0027] The nylon material has excellent toughness, good impact resistance, and is not easy to break, which enhances the structural strength of the carbon spring steel wire and reduces the deformation of the carbon spring steel wire body 1, thereby reducing the probability of fatigue wear.

[0028] Furthermore, the wear-resistant layer 4 is made of polytetrafluoroethylene.

[0029] The wear-resistant layer 4 improves the wear resistance of the carbon spring steel wire body 1, reduces the friction coefficient between the spring steel wire and surrounding objects, and reduces abnormal sounds and noise.

[0030] Furthermore, the positioning bar 401 is a spiral structure, the cross section of the positioning bar 401 is an “M”-shaped structure, the first reinforcing ribs 2 are stuck in the grooves on the surface of the positioning bar 401 , and the second reinforcing ribs 3 and the positioning bar 401 are arranged alternately.

[0031] By clamping the first reinforcing rib 2 and the second reinforcing rib 3 by the positioning bar 401, the stability of the first reinforcing rib 2 and the second reinforcing rib 3 can be ensured, and the first reinforcing rib 2 and the second reinforcing rib 3 can be prevented from being misplaced or displaced during the spring deformation process, thereby improving the stability of the spring support.

[0032] Furthermore, an exhaust hole 402 is provided on the side of the positioning strip 401 .

[0033] When the carbon spring steel wire body 1 is bent and deformed, the first reinforcing rib 2 and the wear-resistant layer 4 squeeze the positioning bar 401, causing it to deform and squeeze out the air inside it. When the carbon spring steel wire body 1 is reset, the pressure is eliminated, thereby sucking the outside air into the positioning bar 401. Frequent exhalation and inhalation can speed up the air flow rate on the surface of the carbon spring steel wire body 1, thereby accelerating its heat dissipation and reducing the thermal fatigue effect caused by frequent deformation.

[0034] Furthermore, an anti-oxidation coating 101 is provided on the surface of the carbon spring steel wire body 1 .

[0035] The anti-oxidation coating 101 improves the anti-oxidation capability of the carbon spring steel wire body 1, thereby preventing oxidation corrosion during use and increasing the service life of the spring steel wire.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
