The most common way to classify springs is by how load is applied to them. You’re probably familiar with the following:Compression spring: designed to operate with a compressive load and found in shock absorbers, spring mattresses, mechanical pencils, and retractable pens. Extension spring: designed to operate with a tensile load. An archetypical example is a Slinky, but these are also found in luggage scales and garage door mechanisms. Torsion spring: designed to operate with torque (twisting force); powers every clothespin and mouse trap.

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 ...

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...

A, definitions,Spring steel refers to the steel specially used to make spring elastic elements due to its elasticity in the quenching and tempering states.The elasticity of steel depends on its elastic deformation capacity, that is, within the specified range, the elastic deformation capacity makes it bear a certain load, and no permanent deformation occurs after the load is removed.Spring steel shall have excellent comprehensive performance, such as mechanical properties (especially elastic limit, strength limit and yield ratio), anti-elastic and anti-elastic properties (i.e. anti-elastic and...

The surface of steel is hardenedIn some parts, the surface layer of the workpiece bears higher stress than the core under the action of alternating loads such as torsion and bending and impact loads.In the case of friction, the surface layer is also constantly worn. Therefore, high strength, high hardness, high wear resistance and high fatigue limit are put forward for some surface layer of parts. Only surface strengthening can meet the above requirements.Because surface quenching has the advantages of small deformation and high productivity, it is widely used in production.According to differ...

Spring is one of the most commonly used parts in the mechanical and electronic products industry. It can produce very large elastic deformation when it is loaded, and this elastic deformation also transforms mechanical work or kinetic energy into deformation energy, which can unload the change of spring, and disappear and return to the original shape, finally, finally. Transformation of deformation energy into mechanical work or kinetic energy. With the continuous progress of the times, the application of spring is very wide, the automobile, computer, TV, pin, phone, cell phone and so on are used in many things in the daily life of the spring. (1) the spring can control the movement of the machine, for example, the valve springs in the internal combustion engine, the control springs in the clutch, etc. (2) it can absorb the energy and impact energy of vibration, for example, the cushioning spring and the vibration absorbing spring in the coupling. (3) it can be used as a power to store and output energy, such as the springs of watches and clocks and the springs in guns. (4) springs can also be used as components for measuring forces, such as springs in dynamometer and spring scales, etc. The ratio of the bearing and the deformation of the spring is the stiffness of the spring as we often call it. The greater the stiffness, the harder the spring is.

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...

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.

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 o...
