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
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.
Package
- 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's the spring material to?
- There are many kinds of spring steel, the most commonly used are 65Mn and 60Si2Mn.
- Q: What kind of material does spring have?
- Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit
- Q: What's the manganese content of spring steel?
- Alloy spring steelAlloy spring steel is based on carbon steel, by properly adding one or more alloying elements to improve the mechanical properties, hardenability and other properties of the steel, to meet the requirements of the manufacture of various springs of steel.The basic composition of series alloy spring steel, spring steel, silicon manganese chromium chromium manganese spring steel, spring steel, spring steel, chromium vanadium tungsten chromium vanadium spring steel. On the basis of these series, some brands added alloying elements such as molybdenum, vanadium or boron in order to improve their performance in some aspects.In addition, other grades of steel, such as quality carbon structural steel, carbon tool steel, high speed tool steel and stainless steel, are selected as spring steel.
- 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: Cold rolled coil spring spring and difference "
- Difference: the main annealing time is different. In the production process, is the first volume of coil spring and annealing, and spring is the first cold roll annealing, and then roll. Similar to cold rolling and hot rolling of steel.Note: spring making methodProduction method of cold rolled coil spring: to stress annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Production method of coil spring: blanking, end processing (rolled or forged flat), heating, coiling, quenching, tempering, grinding end to compression to (load test), shot peening (cleaning), coating.
- Q: How about the size of the elasticity?
- Also called elastic force". The object by the force deformation, if the external force is removed, the object can return to its original shape of the elastic force, called "". Its direction is opposite to the external force that causes the object to deform. There are many different kinds of deformation, so there are different forms of elasticity. For example, when a heavy object is placed on a plastic sheet, the bent plastic should be restored to its original state and produce upward elasticity, which is its support for the heavy object. Hanging an object on a spring, the object stretched the spring, the elongated spring to restore the original state, resulting in upward elasticity, which is its pulling force on the object. Not only plastic, spring and so on can occur deformation, any object can deformation, no deformation of the object does not exist. However, some of the deformation is obvious, can be seen directly; some deformation is very small, must be aware of the instrument.
- Q: How to process Spring Steel
- The available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to form bubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel.
- Q: What are the main functions of spring?
- The storage and release of energy, for example, the clock spring bolt spring
- Q: How to distinguish between spring steel and stainless steel
- With saline in two days to put a steel can see rust is a way (can, for 304 stainless steel 201 stainless steel will rust, only less); another way is to put the two kinds of steel can see the reaction is on spring steel in dilute sulfuric acid, oxalic acid, not the reaction or reaction of small stainless steel.
