 LEAF SPRING FROM BEST MILL WITH LOW PRICE!

Q:The shop glass spring door is too tight, how to adjust?
If it is the glass door of the ground spring, then call the installation worker to loosen it.
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: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
According to the conservation of mechanical energy, the object should be a free fall motion at the upper end of the spring
Q:How to process Spring Steel
Spring steel must pay special attention to decarburization and surface quality during rolling. When the steel surface is seriously decarburization, the fatigue limit of steel will be significantly reduced. For high silicon spring steels, such as 70Si3MnA, caution shall be taken to avoid graphitization. Therefore, stop rolling temperature in hot working time should not be too low (less than 850 DEG C), avoid in the temperature range of graphite is easy to form (650 to 800 DEG C) in the long residence time.
Q:How about the size of the elasticity?
Spring elastic deformation, the elastic limit, the elastic force with the elongation of the spring (or shorten) is proportional to the length (or the length of the spring and the pulling force is proportional to F=-kx (), or delta F=-k delta x). Where k is called the coefficient of stiffness (as a coefficient of rigidity or elasticity) of a spring, in numerical terms equal to the elasticity of a spring when it is stretched (or shortened) in unit length. The unit is Newton per meter, and the symbol is N/m. The K value is related to the nature of the material. The difference between the stiffness and stiffness of springs is that they have different stiffness coefficients. Moreover, the stiffness coefficients of different springs are generally different. The expression in the sign spring caused by its elongation (or compression) in the opposite direction. The law was discovered by British scientist Hooke, known as Hooke's law.
Q:Buffer spring buffer for automobile
With abrasion resistance, cold resistance, impact resistance, aging resistance, water resistance, service life of 2 - 3 years. First, use Jack to support the body and clean the spring with water. After the installation is complete, the automobile damping buffer rotating around a few times, check whether the spring into full spring slot; the outer edge is rub the fender buffer; buffer overlap or not. Also, in order to avoid the shock absorber, when the vehicle is moving down to the bottom of the spring, it is necessary to install a stop card.
Q:How to choose spring steel material?
Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties
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:What kind of production equipment does spring factory usually have?
Multi function forming machine, coil spring machine, 580 press spring machine, extension spring machine, etc.Small heat treatment is also needed
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.
