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:Displacement problems in a spring oscillator
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: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: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
Most of the one-way valves are springs, but the springs are usually soft and the flow resistance can be neglected. Normally, a one-way valve with a pressure of more than 0.3 MPa draws a spring mark on the hydraulic schematic.
Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
It may be that the wire itself is not made of spring.The main performance requirements of spring steel are high strength and high yield limit and fatigue limit, so spring steel has higher carbon content. However, the hardenability of carbon steels is poor, so alloy steels must be used for springs with larger cross sections. The major alloying elements in alloy spring steels are silicon and manganese. They can increase hardenability and yield strength of steel.Carbon steel is used for spring with smaller diameter, and the process is mostly cold drawing, such as 65#, 75#, 85#.The diameter is a little big, and the spring produced by thermoforming process adopts 60Si2Mn, such as automobile leaf spring and buffer spring of railway vehicle.For high stress important spring can use 50CrV, commonly used in advanced sedan leaf spring, engine valve spring, etc..Other spring steel materials include: 65Mn, 50CrMn, 30W4Cr2V, etc..1.2mm diameter is not fine, so it is not hardened, it is too hard to break.
Q:What kind of spring has the best performance?
Spring outside diameter, the same spring at both ends of the outer diameter and the middle of the outer diameter is not the same, unlike the spring, the force has a slight impact. The same batch is very different from each other, indicating that the machining accuracy is very poor.
Q:What kind of production equipment does spring factory usually have?
Spring testing machines; fatigue testing machines; torsion testing machines; spring tension and compression testing machines
Q:Stainless steel and spring steel hardness, who is hard?
Hardness is checked by indentation, not by pliers.Stainless steel, of course
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.
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.
