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

 SPECIFICATION

  Glass Door Floor Spring/Floor Hinge for Glass Door FS-65

     

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's the manganese content of spring steel?
Refer to Baidu Encyclopedia: 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: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: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: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:The glass door spring is broken. How much would it cost to change it?
The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.
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:What kind of spring has the best performance?
Spring verticality, verticality is bad, will directly affect the strength and life.
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:What is flat steel? Plain carbon flat steel? Spring flat steel
Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc.. Square, square section steel, cold and hot points in two; length of hot-rolled square steel 5-250mm; cold drawn steel length 3-100mm. Round - round section steel, hot, forged and drawn three, hot-rolled bar diameter 5-250mm, which 5-9mm used as drawing steel wire material, called wire; due to disk supply is also called hot rod. Forged round steel is thicker, used as axle billet. Cold drawn round steel diameter 3-100 mm, high dimensional accuracy. Flat - width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Angle steel -- two kinds of grade angle steel and unequal angle steel. The dimension of angle iron is expressed by the dimension of the length of side and the thickness of edge. The standard angle steel, usually produced, is 2-20, which is the centimeter side length. Such as 5 equal angles, that is, the length of 5cm (50mm) angle steel. The same horn steel often has 2-7 different edge thickness. Steel bars are not the classification of profiled steel. First, the basic concepts of ferrous metals, steels and nonferrous metals are briefly introduced before introducing the classification of steels, ferrous metals, steels, and nonferrous metals. 1. Ferrous metals are alloys of iron and iron. Such as steel, pig iron, iron alloy, cast iron and so on. Steel and pig iron are both...
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.
