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: Buffer spring buffer for automobile: The automobile spring buffer adopts the cushion principle to reduce the vibration produced by the vehicle during the running, and increase the comfort of the car. When the vehicle is equipped with a spring buffer, the problem of the spring of the shock absorber is effectively solved, the performance of the shock absorber is recovered, and the shock absorber and the suspension system are also protected, and the oil seal of the damping core is avoided. As long as the quality is good and the car to pick their own spring buffer models, can save at least 3 sets of shock absorber overhead, and a shock absorber to several hundred dollars or a thousand dollars, the long term of the owner is indeed a big burden. The new car spring buffer is a buffer of urethane material, not only simple and easy installation, no looseness of vehicle any screws, can make the body up 3 5cm, recovery of the original body height, improve the stability of road safety through deceleration and brake, greatly reduce the fatigue feeling after. The car cushion on the market are made of urethane material, suggest that you choose the buffer glue to the regular manufacturers purchase, on the market there are many inferior or three villages are often unable to get some of the results, some even hurt the shock absorber, shorten the service life of the damping rubber. My friend used Jinke rubber buffer for years should be full, very good quality.

Q: Want to practice how to use pectoral muscle spring expander: Spring expander ah, ha ha this thing is very kindI bought the first exercise equipment is it, when the first day of buying (already pulled out)Let me answer your question1, at least every day to pull more than 200, you can divide into 10 groups, a group of 202 do you have a box for packing when you buy it? It should be illustrated. I bought it before. AMan to show you how to use the most simple method, is placed in the chest, chest behindPull behind the sideways pull, a head in the sole of the foot drop, he slowly realize it3, how long do you need to do this? It depends on how big you areIf you insist on the basic 200 tomorrow, it will be effective in less than a monthGo ahead and hope my answer will help you

Q: Spring dynamometer and spring balance what is the difference: The principle is similar, but the uses are somewhat different

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: 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.

Q: How to choose spring steel material?: The cold plastic deformation of the cold drawn spring material is high, and most finished steel wires have reached the required mechanical properties when the steel mill is out of the factory. The surface quality of the steel wire is high, and the spring manufacturing process is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. This kind of steel wire should be used preferentially for the tension spring with small bending radius and the compression spring with smaller diameter of steel wire. Oil tempered steel wire for residual stress, cold forming, precision spring is easy to control, low temperature tempering after the size change is very small, especially because there is no residual stress relaxation resistance than carbon spring steel wire lead quenching and cold drawing good. For the spring with higher size precision and the thicker diameter of spring steel and the good spring resistance, the oil quenching and tempering steel wire shall be used.

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?: 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 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.
