Elastic limit and yield limit The maximum stress that the steel wire can withstand without permanent residual deformation is called the elastic limit. The steel wire with high elastic limit has large elastic force. According to the use state of the spring, the elastic limit that affects the elastic force can be divided into torsional…
Spring wire and Spring alloy wire Elastic material is a basic material widely used in machinery and instrument manufacturing to make various parts and components. Its main functions in various machinery and instruments are: absorb vibration and impact energy through deformation, and ease the vibration of machinery or parts. And impact; use the energy stored…
Spring Material Mechanical spring is to make full use of the physical properties of materials to store and release energy through certain conversion methods. The characteristics of materials determine the physical and mechanical properties of springs to a certain extent, and affect the design and development of springs and the improvement of special requirements. The…
How to select spring steel wire The selection of spring material shall be determined according to the nature of the load borne by the spring, stress state, stress size, working temperature, environmental medium, service life, requirements for conductivity and magnetic conductivity, process performance, material source, price and other factors. When determining the section shape and…
Spring Material and Application There are many spring materials, and their specific uses are also different. Here, we introduce the related uses. In this way, when selecting the spring material, you can select a more appropriate material according to its purpose. To improve quality and service life of the springs. Product name Steel Specification Main…
Thermomechanical treatment The combination of deformation strengthening and heat treatment strengthening of steel to further improve the strength and toughness of steel. Thermomechanical treatment can be divided into high, medium and low temperature. High temperature thermomechanical treatment is quenching immediately after deformation in the stable austenite state. It can also be combined with forging or…
Correct use of spring Spring is widely used. In the process of use, how to use it correctly can improve the service life and service life of spring Please avoid the following improper use (1) if the maximum compression is exceeded, the pressure will generate and then cause damage. If the spring is used close…
Non metallic protective layer of spring The non-metallic protective layer is to dip or spray a layer of organic substances, such as paint, asphalt and plastic, on the spring surface to protect the spring from corrosion. The non-metallic protective layer has thick film, good chemical stability and good mechanical anti-corrosion effect, but it has low…
Manufacturing method of complex special-shaped spring The invention relates to a forming method and equipment of a linear spring. The equipment includes more than three forming tools that can rotate a certain angle around the main shaft, advance to the center line of the main shaft and impact the wire at the same time, so…
Metal protective coating of spring There are many kinds of metal protective layers. For springs, the metal protective layer is usually obtained by electroplating. The electroplating protective layer can not only protect the spring from corrosion, but also improve the appearance of the spring. Some electroplated metals can also improve the working performance of springs,…
Surface treatment of stainless steel spring Step 1: degrease and scale the stainless steel spring in three ways: 1. Immerse the stainless steel spring into the plastic container with metal cleaning agent a diluted with clean water (the dilution ratio of cleaning agent a and clean water is about 1:1 or 1:2). The time should…
Hardware spring A mechanical part that uses its own deformation to generate force or store energy. Its main functions are: 1.control the movement of machinery, such as valve spring in internal combustion engine, control spring in clutch, etc. 2.Absorb vibration and impact energy, such as buffer spring under automobile and train carriage, vibration absorbing spring…
Introduction to Automobile Spring Coil spring it is the most used spring in modern cars. It has strong shock absorption ability and good ride comfort; The disadvantage is that the length is large, the occupied space is large, and the contact surface of the installation position is also large, which makes the layout of the…
Introduction to air spring It is a precisely designed rubber fiber bellows, which does not provide force or support load, but fills it with compressed air through the air compressor to realize force transmission and elastic effect. According to the requirements for stroke, the air spring is generally designed as 1-3 curves, and can also…
Stainless steel wire for high strength spring In the application of high-strength spring, the early piano steel wire is more common, but the corrosion resistance is very poor. Chromate treatment is required for rust prevention. In the past, crude steel zinc coating was given to make it self-corrosion resistant, but chromate treatment must be carried…
