Q:What are the categories of springs?: The tension spring is a coil spring that bears axial tension. In the case of no load, the coil between the coil and the coil is generally tight and without gaps.

Q:The glass door spring is generally guaranteed for several years: ,expect a warranty to ensure the quality is not very reliable.

Q:Buffer spring buffer for automobile: Rubber buffer also known as buffer, buffer, buffer block, rubber shock absorber, shock absorber rubber and so on, the most correct name is "automobile spring cushion", is the name of Car Spring Buffer Retainer English, 1 luxury cars with a buffer principle significantly improve the damping performance of vehicles.

Q:What's the spring material to?: 1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.

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 is flat steel? Plain carbon flat steel? Spring flat steel: Flat steel, also called flat steel strip, is a long thin steel with a rectangular cross-section. According to the production process, it can be divided into hot rolled flat steel strip, fine shearing flat steel belt and cold drawn flat steel belt.Ordinary carbon flat steel - the component is ordinary carbon structural steel, suitable for wide range.Flat spring - flat steel used for making spring plates of automobiles, containing manganese.

Q:In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position": In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"

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: Is the map tilted?.Look at the picture. It means that a naturally stretched spring is placed vertically and then put a mass of m at zero initial speed.If dropped to the lowest point, the speed of the object v=0, object by the acceleration of gravity g down, if not spring to give it an g greater than or equal to the acceleration, the object will continue to fall, do not conform to the original intention of "low".So the acceleration inside the spring must be greater than or equal to g.

Q:What kind of material does spring have?: 65MnSpring steel belongs to the mechanical structure steel; according to the quality grade, it belongs to the special quality steel, that is to say, in the process of production, it is necessary to strictly control the quality and performance of the steel.

Q:What's the manganese content of spring steel?: Refer to Baidu Encyclopedia: in accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.
