Q:What kind of material does spring have?

In some specific occasions, such as pH and humidity, we often use stainless steel to make springs.The material of the die spring is usually made of chrome alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, great rigidity and long service life.

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:What kind of spring has the best performance?

The length of the spring, with a number of differences between the spring, will affect the product intensity consistency.

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: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:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching

The quenching temperature of the spring depends on the critical temperature of the spring material. After quenching, there should be no free ferrite and cementite in the metallographic structure of the spring material, so as not to lead to uneven deformation or fatigue strength. When quenching, the oxidation and decarburization shall be prevented as much as possible.

Q:How to process Spring Steel

The available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to form bubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel.

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 are the main functions of spring?

Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers

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.
