Detection of geometric size of 6.1 compression springs6.1.1 spring material diameter detection: check the spring material diameter generally with vernier caliper or micrometer. In particular, attention should be paid to the inspection of springs with small winding wires and annealed alloy wires wrapped by automatic spring coiling machines.6.1.2 spring free height or free length detection: the spring is generally placed in horizontal position measurement. It is allowed to be placed in erect position only when the self weight has no obvious effect on the height or length of the spring when it is...

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...

Zinc electroplating: zinc is stable in dry air and changes little. A white film of zinc oxide or carbon zinc carbonate is formed in moist air. This dense film will prevent further corrosion. Therefore, the galvanizing layer is used for the spring corrosion protection under general atmospheric conditions. Zinc coating should not be used for all springs that are in contact with solutions such as sulfuric acid, hydrochloric acid and caustic soda, as well as springs that work in humid air such as sulfur trioxide.Generally, passivation of galvanized coating can improve the protective performance of...

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.

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs. Linear springs Linear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and...

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 lo...

The spring is often corroded by the surrounding medium in the process of manufacture, storage and use.As the spring works under the influence of the spring force, the spring force will change and lose its function after being corroded.Therefore, preventing the corrosion of the spring can guarantee the stability of the spring and extend its service life.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 st...

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 calle...

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 o...
