Q:What is an independent bagged spring?
Independent spring: there are different springs, respectively, according to different weight, set up independent spring in different locations. Of the two men lying on it, one rolled over or left, and the other was not affected at all. Two mattresses in the middle area, the spring has different support strength, so won't feel sleep in the two bed crevice.
Q:Is spring steel manganese steel?
The most important characteristic of manganese steel is that it can be worked hard under strong impact and extrusion, and its wear resistance is improved, mainly by its working hardening.Spring steel mainly requires large elasticity, high yield strength, and can withstand repeated load without breaking. Spring steel only after heat treatment (quenching + medium temperature tempering) can show its high elasticity, that is, after a certain load, does not occur permanent deformation. The content of Mn in spring steel is much lower than that of Mn in manganese steel.
Q:The glass door spring is broken. How much would it cost to change it?
Replace the ground spring, the price of the earth spring itself, but also part of the labor costs, after all, it is very expensive. Land springs in general, if used in general, that is, about 150, but with labor costs, usually around 80. Specific prices should be based on your actual situation, you and the master speak.
Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
It may be that the wire itself is not made of spring.The main performance requirements of spring steel are high strength and high yield limit and fatigue limit, so spring steel has higher carbon content. However, the hardenability of carbon steels is poor, so alloy steels must be used for springs with larger cross sections. The major alloying elements in alloy spring steels are silicon and manganese. They can increase hardenability and yield strength of steel.Carbon steel is used for spring with smaller diameter, and the process is mostly cold drawing, such as 65#, 75#, 85#.The diameter is a little big, and the spring produced by thermoforming process adopts 60Si2Mn, such as automobile leaf spring and buffer spring of railway vehicle.For high stress important spring can use 50CrV, commonly used in advanced sedan leaf spring, engine valve spring, etc..Other spring steel materials include: 65Mn, 50CrMn, 30W4Cr2V, etc..1.2mm diameter is not fine, so it is not hardened, it is too hard to break.
Q:What kind of spring has the best performance?
Spring outside diameter, the same spring at both ends of the outer diameter and the middle of the outer diameter is not the same, unlike the spring, the force has a slight impact. The same batch is very different from each other, indicating that the machining accuracy is very poor.
Q:Buffer spring buffer for automobile
The automobile spring buffer (cushion glue) is a kind of rubber product with high elasticity and high tenacity. It belongs to the automobile refitting parts. The utility model is used for installing the spiral spring of an automobile suspension system, and mainly acts as a buffer shock absorber and protects the shock absorber. This function is a physical function.The buffer is made of an open circular ring with a groove (for holding a coil spring), with two, three or more holes on each side. According to the standard specification of the spring spacing, the buffer rubber is divided into seven standard models: A+A, A, B, C, D, E and F. In theory, these seven models can cover the world's largest part of the spiral spring shock absorbers required.
Q:Stainless steel and spring steel hardness, who is hard?
You should say that the deformation resistance, spring steel generally high strength, large deformation resistance, generally speaking, stainless steel generally than spring steel deformation easier, and some varieties of stainless steel deformation resistance is also very large
Q:The glass door spring is generally guaranteed for several years
Quality and price are pretty much the same. Many other miscellaneous brands of spring can be guaranteed for five years, three years it is best to begin with a reliable brand
Q:What is spring pressure and height?
Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter
Q:How to distinguish between spring steel and stainless steel
Stainless acid resistant steel, or stainless steel, is made up of two parts: stainless steel and acid resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel resistant to chemical corrosion is called acid resistant steel. Spring steel is a quality carbon steel, but it can rust.
