Q: Want to practice how to use pectoral muscle spring expander: Every day until the last time I can not pull itFull pullExercise is a long process

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: 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: General one-way valve is spring to reset, as for drawing may be the standard of drawing is not the same. As long as no oil passes, it closes.

Q: What are the categories of springs?: Linear springs, linear springs from top to bottom of the thickness and density unchanged, the elasticity coefficient for fixed values. The dynamic response of spring of this design can make the vehicle obtain more stable and linear, is conducive to better control the vehicle driver, for vehicle performance orientation and competitive disadvantages of vehicles is of course affect comfort.

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?: The 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.

Q: How to choose spring steel 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..

Q: What kind of spring has the best performance?: Number of coils, coil number is greater than the difference between the 0.25 circle, will directly affect the intensity of emotion.

Q: Cold rolled coil spring spring and difference ": Difference: the main annealing time is different. In the production process, is the first volume of coil spring and annealing, and spring is the first cold roll annealing, and then roll. Similar to cold rolling and hot rolling of steel.Note: spring making methodProduction method of cold rolled coil spring: to stress annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Production method of coil spring: blanking, end processing (rolled or forged flat), heating, coiling, quenching, tempering, grinding end to compression to (load test), shot peening (cleaning), coating.
