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:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching
The quenching temperature of the spring depends on the critical temperature of the spring material. After quenching, there should be no free ferrite and cementite in the metallographic structure of the spring material, so as not to lead to uneven deformation or fatigue strength. When quenching, the oxidation and decarburization shall be prevented as much as possible.
Q:Is spring steel manganese steel?
The most important characteristic of manganese steel is that it can be worked hard under strong impact and extrusion, and its wear resistance is improved, mainly by its working hardening.Spring steel mainly requires large elasticity, high yield strength, and can withstand repeated load without breaking. Spring steel only after heat treatment (quenching + medium temperature tempering) can show its high elasticity, that is, after a certain load, does not occur permanent deformation. The content of Mn in spring steel is much lower than that of Mn in manganese steel.
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
The simplified method of drawing without springs is the same
Q:What is spring pressure and height?
That is, the spring is compressed to the height of the full circle.
Q:How to distinguish between spring steel and stainless steel
Mainly depends on the performance of spring steel, good elasticity, stainless steel toughness. The color should be slightly white stainless steel. Spring steel is easy to rust, with a little salt a day you can see the stainless steel does not rust.
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:Stainless steel and spring steel hardness, who is hard?
Hardness is checked by indentation, not by pliers.Stainless steel, of course
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:Spring dynamometer and spring balance what is the difference
Spring dynamometer and spring balance what is the differenceThis is a question of grade seven (junior one).You didn't answer all right. I found it on the Internet now:The size of the measurement tool called spring dynamometer, dynamometer is a commonly used dynamometer (including spring scale), the experiment is in common is the spring balance.Also, the spring scale is used to measure the force, not to measure the quality.
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).
