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 Floor Hinge/ Door Closer/Floor Spring for Glass Door/Floor Hinge for Glass Door FS-7300

     

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?
Multi function forming machine, coil spring machine, 580 press spring machine, extension spring machine, etc.Small heat treatment is also needed
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:What's the spring material to?
1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.
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:What is spring pressure and height?
Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter
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: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: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
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:How to process Spring Steel
Ha ha, friend,At first I thought it was a springFirst, you want to buy hot, or annealed spring steel, the standard number is GB/1222-2007< more than and 10 grades, including you 65 and 60 Si 2 A> Meng MengI'll probably help you figure it out. There are so many processes1 turning 2 milling machine processing openings 3 heat treatmentWell, I'm going to work, tooI hope my answer is of some use to you
