packaging system of torsion springs

Q: Stainless steel and spring steel hardness, who is hard?: Hardness is checked by indentation, not by pliers.Stainless steel, of course

Q: What is spring pressure and height?: That is, the spring is compressed to the height of the full circle.

Q: What are the categories of springs?: A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and are restored to original shape after removal of external forces. Also made as a spring". Usually made of spring steel. The type of spring is complex and varied. According to the shape, there are mainly spiral spring, scroll spring, plate spring, special-shaped spring and so on.

Q: Can springs be used for support?: If there is a condition, the upper and lower parts of the spring are mounted, similar to the bearing parts, and more thoroughly separated from the gears.

Q: What's the manganese content of spring steel?: Alloy spring steelAlloy spring steel is based on carbon steel, by properly adding one or more alloying elements to improve the mechanical properties, hardenability and other properties of the steel, to meet the requirements of the manufacture of various springs of steel.The basic composition of series alloy spring steel, spring steel, silicon manganese chromium chromium manganese spring steel, spring steel, spring steel, chromium vanadium tungsten chromium vanadium spring steel. On the basis of these series, some brands added alloying elements such as molybdenum, vanadium or boron in order to improve their performance in some aspects.In addition, other grades of steel, such as quality carbon structural steel, carbon tool steel, high speed tool steel and stainless steel, are selected as spring steel.

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: Is the car short spring good?: Hello: no modification is recommended! Although the spring shortening can reduce the height of the body to make the car appear more sporty, it can also reduce partial roll during cornering. But it does more harm than good. Below say, change the disadvantage of short reed. First of all, lowering the body will affect the passing, and the over speed belt is easy to drag the chassis. Another major drawback is that the full set of shock absorbers consists of a helical spring and a hydraulic cylinder shock absorber.

Q: How about the size of the elasticity?: Stretch by the object, extrusion and elastic deformation, the elastic solution is to look at the state of the object, at rest or in uniform linear motion of an object according to the stress analysis of the relationship between the force and other force, curve movement or acceleration force balance objects can analyze the stress in Newton's second law for, no matter what type of stretch can use the two methods to solve the hope to adopt: -)

Q: How to process Spring Steel: After the spring is made, shot peening can produce residual compressive stress on the surface of the spring so as to offset part of the working stress on the surface layer and restrain the formation of surface cracks, which can significantly improve the fatigue limit of the spring.

Q: Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert: For small spheres, the energy is conserved from the free fall to the ultimate spring compression equal to the maximum value of XMgX=0.5kX^2 (this formula is obtained by integration, do not know if you have no calculus)Calculate X=2mg/k, then the lowest point is the resultant force of the ball is kX-mg=2mg-mg=mg, in the direction of acceleration, the size is exactly equal to GIf the ball is considered to fall from high, then the energy conservation before it converts the energy of the potential energy into springs is naturally more, and the acceleration of the lowest point ball is greater than g
