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:Is the car short spring good?
The factory is a hydraulic cylinder, and the damping force and the length of the expansion are matched with the length of the spring and the telescopic distance. Instead of changing the short spring will increase the load of the original vehicle hydraulic shock absorber, shock quickly destroy.
Q:How about the size of the elasticity?
The force is analyzed and the force is decomposed along the positive plane and its vertical direction
Q:How to process Spring Steel
Spring steel has excellent comprehensive performance, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization, precise shape and size).
Q:How to choose spring steel material?
In choosing materials, the material shall be considered in combination with the diameter or thickness of the material. The size of commonly used spring steel in oil is shown in table 3-10.7mm below diameter carbon spring steel used for oil quenching, the size of all kinds of spring is slightly larger, available manganese spring steel quenching. Well, such as 65Mn spring steel 15mm diameter can be through quenching in oil, available water quenching diameter of 25mm. For the spiral spring, leaf spring and disc spring middle section can be used manganese spring steel, 60Si2Mn steel can be used as oil quenching diameter of 25mm, for the spring to withstand heavy loads with large cross section, can choose the hardenability of high chromium silicon steel, chrome vanadium steel wire, such as 60Si2CrA.50CrVA, 45mm in diameter can also through quenching in oil.
Q:Is spring steel manganese steel?
With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.
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: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: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 material does spring have?
Carbon spring steel: the material: 65#, 70#, 65Mn, 82B, 72A, 72B steel, is characterized by low plasticity, strong elasticity, anti stress ability. Application: mainly used for Simmons bed, car cushion, and all kinds of machinery, electric tools, stationery, sports equipment, torsion spring, spring, electrical equipment and other industries. Specifications: line diameter 0.20mm- GB4357-89 6.50mm. standard: carbon spring steel wire, national standard, main use: used to make cold formed in the cold state without hardening spring
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
