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

 

      Hydraulic Door Closer /Floor Spring/Floor Hinge for Glass Door FS-71 

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: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"
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: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:The glass door spring is generally guaranteed for several years
but once you change the maintenance fees are higher than the artificial spring spring price itself
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:What are the main functions of spring?
The storage and release of energy, for example, the clock spring bolt spring
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.
Q:Is spring steel manganese steel?
Spring steel is not manganese steel, there are many kinds of spring steel, manganese 65 is more commonly used spring steel, as well as carbon spring steel and alloy spring steel.Manganese steel refers to the high manganese content of carbon steel structural steel.
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: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: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.
