Q:What are the main functions of spring?
Measure the magnitude of forces, such as springs, scales, and springs in a dynamometer
Q:The glass door spring is generally guaranteed for several years
but once you change the maintenance fees are higher than the artificial spring spring price itself
Q:How should we choose the spring material?
Whether the spring is good or not is of great importance to the choice of the spring material. In general, selection of spring material, should take into account the load properties, spring force, various factors should be size, working conditions and price, etc.. Specific can follow the following principles: 1) in determining the shape and size of spring material, should be preferred dimensions behind national standards or standard stipulated, try to avoid using non standard materials. Although the spiral spring square or rectangular cross section material, the elastic deformation can be higher than, can make the small volume of the spring, for spring, in small space or under impact load but because of square or rectangular section material shortage, the price is higher, and the spring forming is difficult, so should be avoided. Ring section spring material diameter series see table 3-9. 2) the degree of cold plastic deformation of cold drawn spring materials is high. Most finished steel wires have reached the required mechanical properties when they leave the factory. The surface quality of the steel wire is high, and the manufacturing process of the spring is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. For the bending radius of smaller tension and torsion spring, as well as smaller steel wire compression...
Q:How to choose spring steel material?
In choosing materials, the material shall be considered in combination with the diameter or thickness of the material. The size of commonly used spring steel in oil is shown in table 3-10.7mm below diameter carbon spring steel used for oil quenching, the size of all kinds of spring is slightly larger, available manganese spring steel quenching. Well, such as 65Mn spring steel 15mm diameter can be through quenching in oil, available water quenching diameter of 25mm. For the spiral spring, leaf spring and disc spring middle section can be used manganese spring steel, 60Si2Mn steel can be used as oil quenching diameter of 25mm, for the spring to withstand heavy loads with large cross section, can choose the hardenability of high chromium silicon steel, chrome vanadium steel wire, such as 60Si2CrA.50CrVA, 45mm in diameter can also through quenching in oil.
Q:What's the spring material to?
65Mn, 55Si2Mn, 60Si2Mn, 50CrVA, 75, 85, 55CrMnA, 60Si2CrVA, 60Si2MnA, 70, 65, 50CrMo, 55SiMnMoVNb, 60SiMnMoA, 65Si2MnWA, 70Si3MnA, and so on
Q:Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated
Most of the one-way valves are springs, but the springs are usually soft and the flow resistance can be neglected. Normally, a one-way valve with a pressure of more than 0.3 MPa draws a spring mark on the hydraulic schematic.
Q:How to distinguish between spring steel and stainless steel
With saline in two days to put a steel can see rust is a way (can, for 304 stainless steel 201 stainless steel will rust, only less); another way is to put the two kinds of steel can see the reaction is on spring steel in dilute sulfuric acid, oxalic acid, not the reaction or reaction of small stainless steel.
Q:What kind of spring has the best performance?
The length of the spring, with a number of differences between the spring, will affect the product intensity consistency.
Q:Spring dynamometer and spring balance what is the difference
The principle is similar, but the uses are somewhat different
Q:What kind of material does spring have?
Carbon spring steel: the material: 65#, 70#, 65Mn, 82B, 72A, 72B steel, is characterized by low plasticity, strong elasticity, anti stress ability. Application: mainly used for Simmons bed, car cushion, and all kinds of machinery, electric tools, stationery, sports equipment, torsion spring, spring, electrical equipment and other industries. Specifications: line diameter 0.20mm- GB4357-89 6.50mm. standard: carbon spring steel wire, national standard, main use: used to make cold formed in the cold state without hardening spring
