1) high strength: in order to improve the spring's ability to resist fatigue failure and relaxation, the spring material should have a high yield strength and elastic limit, and in particular, a high ratio of strength to strength.In general, the elastic limit of the material is directly proportional to the yield strength, so the spring design and the manufacturer always want the material to have a high yield strength.The tensile strength and yield strength of the spring material are close, for example, about 90% of the carbon steel wire of cold drawn is about: since the tensile strength is eas...

Spring is a kind of elastic element widely used in the mechanical and electronic industries. Spring can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is transformed into mechanical work or kinetic energy.The ratio of load and deformation of the spring is called spring stiffness.  There are many kinds of springs. They are used in various fields. According to the deformation condition, they can be divide...

compression spring is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful also rectangle and multi-strand steel rolled a travelling, spring is usually pitch, such as the shape of the compression spring are: cylindrical, conical, convex and concave and a small amount of noncircular, compression spring there is a certain gap between circle and circle, when under external load spring contraction deformation, deformation energy storage.The tension spring is a spiral spring that bears the axial tension.When there is no load, the stretch spring is usual...

Compression springs are frequently seen and used in daily life. The main principle of compression springs is to provide a hand to the machine and drive it to work.The compression spring has a certain damping capacity, because the product's elastic force is not a fixed value, so every time it is used, there will be a return force, and the force is not a fixed size, which to some extent has the ability to slow down the vibration.As an example, now the car is installed above a compression spring, you will find when driving, its speed is greatly improved, and the movement process there is no sound...

The corrosion of spring can be divided into chemical corrosion and electrochemical corrosion according to the type of reaction.They are the result of changes in the metal atoms on the surface of the spring or the loss of electrons to an ionic state.If the metal on the surface of the spring simply reacts with the surrounding medium, and the spring causes corrosion, it is called chemical corrosion.For example, the spring is oxidized in the particularly dry atmosphere to form an oxidation film, and the spring is chemically changed with the liquid or impurity in the non-electrolyte liquid, which i...

The purpose of mold spring is to take off material, press material, the strength of the spring, which is related to whether the mold production is smooth, whether the product is qualified.Spring force is small, may cause the product to be out of shape, the mold does not take off the material, the product is bad to take out from the mold inside, the belt material, the knife edge, punch easy to wear and so on each kind of question.Mold spring according to different production times, compression amount selected, the larger the spring life, the shorter die life, of course, the broken spring can be...

Spring steel wire will generate residual stress during the process of cold drawing and oil quenching and heat treatment. Moreover, spring wire is formed during the process of manufacturing and shot peening is conducted.High frequency quenching, carburizing, nitrification, etc. are used as surface hardening treatment. As a result of these treatments, residual stress will be generated in the material.The qualitative and quantitative analysis of the residual stress of the material will be an important factor to improve the fatigue properties of the spring.Residual stress of the spring is usually ...

Nowadays, with the development of science and technology, spring has become a very important hardware accessory in our life. Different products use different springs, and the longest used springs can be roughly divided into: pull spring, twist spring, press spring, disc spring and plate spring.The following features of a very practical tension spring:Many different products or hooks are used to guarantee the source of the tension of the tension spring. The tension spring works in the opposite way to the compression spring. The tension spring works in the opposite way when stretching or pulling...

In the actual work, we often encounter that the spring cannot push the moving object to the set position, that is to say, the length of the spring's computational freedom becomes shorter.The main reason is that there is no initial compression, that is, a spring is made into a spring, which is compressed to its compression height or to its compression height (if necessary) with a greater force, and cannot be restored to its original free length upon release.Its shortened quantity is called "initial compression quantity".After repeating 3-6 times of compression, the length is no longer...

The selection of spring material shall be determined according to the properties of the spring bearing load, stress state, stress size, working temperature, environmental medium, service life, requirements for conducting and magnetic conductivity, technical performance, material source and price, etc.When determining the shape and size of the material section, the series sizes specified in the national standards and ministerial standards should be selected first, and non-standard series of materials should be avoided as far as possible.Medium and small-sized springs, especially spiral-tension ...

For a long time, the shape and performance of the extension spring will change. If the extension spring is always in a certain situation, it may change its quality due to external conditions.Generally, there are the following situations:I. wear of extension spring :Wear can be divided into abrasive, fatigue and corrosion wear fracture.Ii. Brittle fractureThe majority of spring break belongs to brittle fracture.Plastic fracture is possible only when the working temperature is high.In engineering, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle ...

Torsion spring is a mechanical force storage structure, mainly used in ancient crossbow guns and other crossbow.The torsion spring accumulates the force through the twist or rotation of the elastic material with a relatively soft and pliable material, and makes use of it so that the projectile has certain mechanical energy.The modern torsion spring torsion bar is made of excellent elastic steel, and the form is also changed a lot, including the wire on the inner surface of the mechanical watch, the power spring in the toy gyroscope gun, as well as the torsion bar in the tank and car.Small...

In order to make it convenient for customers to buy and custom spring, some brief introduction about spring and specification parameters are summarized as follows:The common spring can be classified as: stretching spiral spring, compression spiral spring and torsion spiral spring.Among them, stretch and compression springs are mostly produced in quantity, with complicated specifications but suitable for slight modifications. If a small amount of springs is needed and the characteristics of springs are not critical, they can be purchased easily in the market with a higher unit price.The users o...
