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...

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...

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 spring should ideally conform to hooke's law, that is, the relationship between stress and strain in the elastic range is linear.However, since the actual spring steel is a polyphase and polycrystalline material, there must be inconsistencies in composition, structure, elasticity, etc., and the stress and strain deviated from the linear relationship within the elastic range, which is called elastic incompleteness or anelastic.The phenomena such as elastic after effect, elastic lag, stress relaxation and elastic modulus decrease are produced.After tempering, the stabilization process can re...

The spring relief valve is mainly composed of spool, seat, stem, spring and adjusting screw.The relief valve mainly USES spring force to press the spool on the seat.When the boiler pressure exceeds the pressure exerted by the spring on the upper part of the spool, the spool and stem are lifted and steam is discharged.When the boiler pressure is lower than the spring pressure acting on the upper part of the spool, the spool falls on the seat and the boiler stops discharging steam.The spool is a cone with a slight protrusion around the edge of the spool.When the steam opens the valve core, the e...

1. The standing treatment of the compression spring is to compress the spring to the working limit height or to tighten the height several times, usually 3 to 5 times;For the stretching spring, the length of the spring is drawn to the working limit several times;Torsion spring, is the spring in the working direction of the 5522 for the ultimate torsion Angle several times.2. Strong pressure (strong tension and strong torsion) treatment for compression spring is to press the spring into the material layer and the stress exceeds the yield point, resulting in negative residual stress on the surfa...

1, matching springs and springs based on automobiles, motorcycles, diesel engines and gasoline engines. This type of spring has valve spring, suspension spring, damping spring and clutch spring, etc., with a large amount, which accounts for about 50% of the spring production. At the same time, the technical level is also high, it can be said that the technical level of these springs is representative, they are mainly to the high fatigue life and high anti relaxation direction, thus reducing the quality.

 

2. Large springs and plate springs, which mainly include railway rolling stock, heavy truck and engineering machinery, are mainly formed by hot coil forming, which is an important aspect of the spring manufacturing industry. With the development of high-speed railway and the upgrading of the vehicle damping system, the technology of the thermoforming spring for vehicle suspension has been greatly improved. This kind of spring mainly develops to the high strength and high precision direction in order to stabilize the quality of the product.

 

3, the electronic appliance spring based on instrument and instrument, typical products such as motor brush spring, switch spring, camera and camera spring, and computer accessories spring, instrument and instrument fittings spring and so on. The spring and special-shaped springs in such springs account for a large proportion. Different products have different material and technical requirements. This type of spring develops mainly in the direction of high strength and miniaturization.

 

4, the hardware springs, such as mattress, sofa, door hinge, toy, lighter and so on, have large demand for this type of spring, such as mattress, sofa, door hinge, toy, lighter and so on. But the technical content is not high, which has improved the development opportunity for small spring enterprises. This kind of spring is mainly made to the direction of miniaturization.

Constant force spring, or “clock” spring, is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant.   Such applications as brush springs for motors, counterbalance springs for window sashes and carriage return springs for typewriters. Constant force motor springs are used to drive mechanisms for timers, movie cameras and cable retractors.Constant force spring also known as coil spring helix in a plane of the spring, Spring is the material wound into a plane of the spiral of a spring, the spring is fixed at one end, the other end of the material after acting torque bending torque, bending elastic deformation, so the spring in its own plane to p...

A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. They are usually coiled at a constant diameter, though they can be coiled in other needed forms such as conical, concave (barrel), convex (hourglass), or various combinations of these. Compression springs are used to resist force and/or store energy,1、CharacteristicsBy far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. 2、Service LifeIt should be noted that if critical force-versus-deflection linearity is required, only the center 60-80% of the available deflection range should be employed.Thus, reserve at least the first and last 15-20% of t...

When choosing the right spring, selecting the best spring wire is a critical before manufacturing. Below are some of the most common spring wire materials and their unique characteristics .Stainless Steel SpringsStainless steel springs have low-stress relaxation and resist corrosion. They have good strength at moderate temperatures and are resistant to heat. Extension springs are most commonly made from stainless steel.Extension springs absorb energy and provide resistance to pulling. As the name suggests, an extension spring stretches as a load is applied to it. Applications for extension springs include carburetors, trampolines and farm machinery.Oil Tempered Spring WireOil tempered wire is cold drawn and heat treated before plating. Ideal as a general purpose spring wire, it is often us...

springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its original stat...
