Salt fog refers to the dispersion system composed of salt micro droplets in the atmosphere. It is one of the three defense series of artificial environment. Many enterprise products need to simulate the destructive nature of the marine surrounding climate to the products. The salt fog test is a simulation of this phenomenon, so the test equipment, salt fog test box, came into being.Salt fog can be divided into two categories, one is natural environmental exposure test, the other is artificial accelerated salt spray environmental test. The artificial simulated salt fog environment test is a kin...

The spring is often subjected to variable load or impact load. In order to ensure that the spring can work permanently and reliably, the material must have high elastic limit and fatigue limit. At the same time, it should have enough toughness and plasticity and good heat treatment.Spring materials and properties can be consulted in relevant manuals, specifications and standards (GB/T129.6-92, GB4357-89). The common spring steel is mainly:1: carbon spring steelThis kind of spring (such as 65, 70 steel, etc.) has the advantages of cheap price, convenient source of raw materials, low elastic lim...

There are two types of heat treatment deformation: one is the size change, the other two is the change of part geometry. Different methods of heat treatment, deformation and deformation prevention of parts size and geometry are also different.The longer the holding time and the higher the temperature are, the more carbon is dissolved into austenite and the larger the expansion of martensite is. The expansion of martensite is the largest, followed by upper bainite, and the volume change of lower bainite and troostite is very small. At low temperature tempering, martensite shrinks and the amount...

Hard inspection method for chemical heat treatment and surface quenching and temperingSurface heat treatment is divided into two categories, one is chemical heat treatment and the other is surface quenching and tempering heat treatment. The hardness test method is as follows:1. Chemical heat treatmentChemical heat treatment is to make the workpiece surface infiltrate one or several chemical elements of the atom, thereby changing the workpiece surface chemical composition, organization and performance.After quenching and tempering, the surface of the workpiece has high hardness, wear resistance...

Wire forming spring is a mechanical part that uses elasticity to work. It is usually made of spring steel. It is used to control the movement of machine parts, to mitigate impact or vibration, to store energy and to measure the magnitude of force. It is widely used in machines and instruments.The spring is just an accumulator. It has the function of storing energy, but it can not release the energy slowly. To realize the function of releasing slowly, it should be realized by "Spring + large transmission ratio mechanism", which is common in the mechanical meter.Spring is a kind of ela...

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 springsLinear 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 i...

(1) heat treatment technology for strengthening springs.1) protective atmosphere heat treatment. In our country, protective atmosphere heat treatment is adopted in spring, oil quenched and tempered steel wire and toughened steel whose wire rod is less than 15mm. Heat treatment in protective atmosphere can remove surface decarbonization and oxidation and improve the surface quality of materials.2) induction heating or protective atmosphere induction heating heat treatment. This process is usually carried out on the wire before forming the coil spring. Some spring factories combine heat treatmen...

1、What is Passivation?As a post-fabrication method, passivation is intended to maximize the natural corrosion resistance of stainless steel. Stainless steel is a steel alloy that contains a minimum of 10.5% chromium content by mass and along with a number of other alloys. When stainless steel is newly formed it needs to be cleaned of lubricants, oils, greases and other substances used in its fabrication. Once the steel has been cleaned it must be passivated. Passivation is a process that treats metal surfaces with an acid solution to make the surface corrosion resistant.Passive to atmospheric ...

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...

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...
