INTRODUCTION

    

Floor Spring is used for glass door, and they can be used together with door clamp. Floor Spring can be opened with double sizes, and on this point, it is different from that of door closer, which can just be opened by one size.  The key of technique lies on the loading seat under the main bearing, which decides the level of loading on the floor spring. Usually it can be opened from 300thousand or 1million times

INSTALLATION STEPS

 

1.      Draw lines and make floor spring pivot center and door-nip pivot coincide with each other.

2.      Drill holes on the floor according to the instructions. The sizes of the holes must tightly match the floor spring.

3.      Place the floor spring into the holes and position it.

4.      Raise the door leaf installed with door-nip, and insert the floor spring pivot into the hole of the door leaf.

5.     Adjust the screws at three directions. Make them vertical and the upper and lower pivot center coincide with each other.

6.      Adjust the speed of door closing.

7.      Put the decoration cover on the floor spring.

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:What is an independent bagged spring?
Independent bagged spring is a spring with non-woven package, barrel type design can prevent the spring friction and swinging or noise, no influence between spring, elastic energy in accordance with the size of individual expansion, different weight average and proper support of various parts of the body to keep the spine straight, make sleep more comfortable. Bagged spring than ordinary spring production process is more complicated, the cost is higher, so the price is slightly expensive. But human health is obviously.
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
For small spheres, the energy is conserved from the free fall to the ultimate spring compression equal to the maximum value of XMgX=0.5kX^2 (this formula is obtained by integration, do not know if you have no calculus)Calculate X=2mg/k, then the lowest point is the resultant force of the ball is kX-mg=2mg-mg=mg, in the direction of acceleration, the size is exactly equal to GIf the ball is considered to fall from high, then the energy conservation before it converts the energy of the potential energy into springs is naturally more, and the acceleration of the lowest point ball is greater than g
Q:What are the main functions of spring?
There are many kinds of spring, and the spring is mainly divided into four kinds: stretching spring, compression spring, torsion spring and bent spring. If in accordance with the spring shape and can be divided into helical springs, disc springs, ring spring, plate spring, spring etc.. The basic types of springs are listed in the table. Air springs.
Q:How to choose spring steel material?
The cold plastic deformation of the cold drawn spring material is high, and most finished steel wires have reached the required mechanical properties when the steel mill is out of the factory. The surface quality of the steel wire is high, and the spring manufacturing process is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. This kind of steel wire should be used preferentially for the tension spring with small bending radius and the compression spring with smaller diameter of steel wire. Oil tempered steel wire for residual stress, cold forming, precision spring is easy to control, low temperature tempering after the size change is very small, especially because there is no residual stress relaxation resistance than carbon spring steel wire lead quenching and cold drawing good. For the spring with higher size precision and the thicker diameter of spring steel and the good spring resistance, the oil quenching and tempering steel wire shall be used.
Q:What are the categories of springs?
The tension spring is a coil spring that bears axial tension. In the case of no load, the coil between the coil and the coil is generally tight and without gaps.
Q:What's the spring material to?
65Mn, 55Si2Mn, 60Si2Mn, 50CrVA, 75, 85, 55CrMnA, 60Si2CrVA, 60Si2MnA, 70, 65, 50CrMo, 55SiMnMoVNb, 60SiMnMoA, 65Si2MnWA, 70Si3MnA, and so on
Q:Can springs be used for support?
The following individual ideas do not represent the bestFriction is bound to damage,Gaskets can be used to prevent direct friction between the spring and gear to lubricate, optimize wear and prolong life.
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.
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
