Spring basics overview
Springs are a mechanical element capable of storing and releasing energy and are widely used in various mechanical equipment and industrial products. Depending on the context and requirements of the different applications, springs can be divided into different types, common among which are compressed springs, stretch springs, reverse springs, etc. The following is a detailed description of the type, material, process and design of the spring:
The type of spring
(1) compressed springs: compressed springs are springs that reduce the length of stress and are usually used in various mechanical devices in terms of shock reduction, support and maintenance。
(2) the stretching spring: the stretching spring is a spring that stretches long at stress and is usually used in connection, movement and support in various mechanical devices。
(3) reversing springs: reversing springs are springs that reverse deformation in the event of stress and are usually used in the movement and support of various mechanical devices。
The spring material
The spring materials are usually selected for materials such as high-strength, high-resilient, high-resilient alloy steel, stainless steel and copper alloy. Of these, alloy steel is the most commonly used spring material with high intensity, resilience, high resistance to fatigue and good weldability, and is suitable for the manufacture of springs。
Spring process
The spring manufacturing process usually consists of the following steps:
(1) raw material preparation: select suitable spring materials and perform pre-treatment processes such as cutting, heat treatment, etc。
(2) spring scrolling: the pre-processed material is lumped into spring shapes, usually made of mechanical rollers or manual rollers。
(3) thermal treatment: thermal treatment of curled springs to increase their strength and resilience。
(4) surface treatment: surface treatment of thermally processed springs to improve their corrosivity and beauty。
(5) inspection and packaging: testing and packaging of manufactured springs to ensure their quality and usefulness。
Design of springs
The spring is designed to take into account a number of factors, including the application of the spring, stress, work environment, useful life, etc. When designing springs, parameters such as materials, shape, size, elasticity factors, etc., need to be determined to meet their requirements during use. At the same time, analysis of spring strength calculations, fatigue projections, etc., is required to ensure the safety and service life of springs。
