Q:Want to practice how to use pectoral muscle spring expander: The most simple way you can lie on the bed or on the floor and chest stretching is very effective and pay attention to more, so as not to hurt the small set of muscles.It takes at least one month to bear fruit

Q:What are the categories of springs?: The coil spring, the torsion spring, is a spring that bears torsional deformation, and its working part is tightly wound into a spiral shape. The torsion spring end is made of twisted arms of various shapes rather than rings.

Q:How about the size of the elasticity?: Also called elastic force". The object by the force deformation, if the external force is removed, the object can return to its original shape of the elastic force, called "". Its direction is opposite to the external force that causes the object to deform. There are many different kinds of deformation, so there are different forms of elasticity. For example, when a heavy object is placed on a plastic sheet, the bent plastic should be restored to its original state and produce upward elasticity, which is its support for the heavy object. Hanging an object on a spring, the object stretched the spring, the elongated spring to restore the original state, resulting in upward elasticity, which is its pulling force on the object. Not only plastic, spring and so on can occur deformation, any object can deformation, no deformation of the object does not exist. However, some of the deformation is obvious, can be seen directly; some deformation is very small, must be aware of the instrument.

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.

Q:What's the spring material to?: There are many kinds of spring steel, the most commonly used are 65Mn and 60Si2Mn.

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

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: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: Certain large diameter one-way valves have no springs, and steel balls rely on gravity return. These valves usually require vertical mounting.In fact, in the oil flow driven, the ball will always reset, no spring one-way valve can also be closed. Only the closing action has hysteresis, better than the spring back reliable.

Q:What kind of material does spring have?: Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit

Q:What's the manganese content of spring steel?: Carbon spring steelThe carbon content (mass fraction) of carbon spring steel is usually 0.62%~0.90%. 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.
