In life, tension springs can be seen everywhere, and they are used in many jobs. tension springs are cleaned and polished in daily use. 1. Take an appropriate amount of clean water, and mix and dilute the cleaning agent A and clean water in a ratio of 1:1 or 1:2. Put the diluted solution in a plastic container for later use. Put the tension tension spring to be cleaned into the container to soak. The soaking time should not be too long. When the surface of the tension spring has no oil stains and restores the original metallic color, take it out and use it. The clean water opens the scouring, so that the surface layer has a matte actual effect. 2. Take some coarse abrasives, put them in the cleaning agent, and then put them into the hexagonal drum. The volume ratio of the tension spring to the coarse abrasives is 1:3, and the amount of cleaning agent is 1%-2% of the tension springcomponent. It is opened in the inside for plenty of grinding, and then cleaned with water, so that the scratches on the surface of the spring will not exist. This operation can improve the surface finish of the spring very well, but it is not suitable for the use of high-precision tension springs. Under some operating conditions, this situation may also be encountered. When the operating medium or industrial products produced, even if a trace of a certain or certain metal ion is contained, it will affect the chemical process and industrial products. Quality (including gloss, color, purity, etc.). This situation is most common in industries such as nuclear fuel pharmaceuticals and pigments. At this time, the corrosion resistance levels that do not contain a certain element or are properly run are used to reduce the metal ions to the allowable limit.

Tension spring refers to a spring that can work in weakly corrosive media such as electronics, air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. In many working environment requirements such as chemical machinery and electronics, it is an elastic element that is corrosion-resistant, resistant to medium temperature and non-magnetic. The tension spring can produce relatively large elastic deformation when it is loaded, converting mechanical function or kinetic energy into elastic potential energy. When unloaded, the deformation of the tension spring will disappear and return to its original state, transforming the deformation energy into mechanical function or kinetic energy. Tension spring has excellent general functions, such as: mechanical function (especially elastic limit, strength limit, yield ratio), elastic reduction function (that is, elastic reduction function, also known as anti-loosening function), fatigue function, hardenability , Physical and chemical functions (heat resistance, low resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above functional requirements, the tension spring has excellent metallurgical quality (high purity and uniformity), excellent appearance quality (strict control of appearance defects and decarburization), precise shape and size. Generally, cylindrical springs are simple to manufacture, so they can be made into various types according to the load conditions, with simple structure and the most widely used. Generally speaking, tension springs should have high elastic limit, fatigue limit, impact toughness and excellent heat resistance and corrosion resistance. Commonly used spring wire with a diameter of less than 20 mm is cold-rolled. After the tension spring is made, it must be pressed or polished to improve the load-bearing capacity and surface finish of the spring.

Overview of cylindrical spiral spring | spiral torsion spring 1、 Structure of cylindrical tension and compression helical spring Cylindrical spiral spring is divided into compression spring and extension spring. The compression spring is shown in the figure. Usually, the end rings at both ends are tightened and ground flat. There is also a kind of two end rings and tight but not smooth. The smooth part shall not be less than 3 / 4 of the circumference, and the end thickness shall not be less than D / 8. 2、 Geometric dimensions of cylindrical helical spring The main geometric dimensions of the cylindrical spiral spring are: spring wire diameter D, outer diameter D, inner diameter D1, medium diameter D2, pitch P, helix rising angle α、 Free height (compression spring) or length (tension spring) H0, as shown.

I believe many people have used mechanical keyboard. My friends who also use the mechanical keyboard say that the mechanical keyboard is really one of the most beautiful existence in the world! However, as one of the parts of mechanical keyboard, have you ever thought about the role of spring in mechanical keyboard? In fact, the spring plays the role of compression and rebound in the bearing of mechanical keyboard. A large part of the mechanical keyboard's handle and use times are determined by the spring of the bearing base. According to different bearings (such as black axis, red axis, green axis, tea axis), the spring length, pressure and other specifications are also different. What spring is better for mechanical keyboard? | Keyboard Compression Spring

In daily life, tension springs are widely used, so how to improve the service life of tension springs? 1. Austempering of tension spring. For springs with a relatively small diameter or satisfactory hardenability, austempering can be selected, which can not only reduce decentering, but also improve its resistance. After austempering, it is best to perform another tempering, which can increase the limit of elasticity. It should be noted that the tempering temperature should be the same as the austempering temperature. 2. Deformation heat treatment. Thermomechanical heat treatment is mainly to combine the deformation strengthening of steel with heat treatment strengthening, so as to further improve the strength and resistance of steel. Thermomechanical heat treatment can be divided into high temperature, medium temperature and low temperature. High temperature thermomechanical heat treatment is formed in a stable condition, and then it should be quenched immediately, or it can be combined with casting or hot rolling, that is, quenching immediately after hot forming. 3. The tension spring should be slack after quenching and tempering. The spring works under the action of external force for a long time, because the stress is slack, it will produce a small amount of permanent (plastic) deformation, especially the high-temperature working spring, the stress slack phenomenon is more serious at high temperature, so that the accuracy of the spring is reduced. It is not allowed for precision springs. Therefore, the tension spring should be slackened after quenching and tempering. Heat treatment process: Load the tension spring in advance, so that its deformation exceeds the deformation that may occur during operation of the spring. Then heat it at 20°C higher than the operating temperature for 8-24 hours. 4. Shot peening. Tension springs have higher requirements for surface quality. Surface defects such as scratches, folding, oxidative decarburization, etc. tend to become stress collection places and fatigue cracking sources during spring operation. Shot peening is one of the most widely used methods to improve the surface quality of springs. If fine steel sho
