Q:How should we choose the spring material?: The selection of spring materials shall be determined according to the nature of the load, stress state, stress magnitude, working temperature, working environment and service period of the spring.

Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching: Spring: Spring quenching hardening is the steel is heated to the critical temperature of Ac, or Ac: the above heat preservation time, the austenite with greater than the critical cooling rate of rapid cooling, so as to obtain the heat treatment method of martensite.

Q:Is the car short spring good?: Hello: no modification is recommended! Although the spring shortening can reduce the height of the body to make the car appear more sporty, it can also reduce partial roll during cornering. But it does more harm than good. Below say, change the disadvantage of short reed. First of all, lowering the body will affect the passing, and the over speed belt is easy to drag the chassis. Another major drawback is that the full set of shock absorbers consists of a helical spring and a hydraulic cylinder shock absorber.

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:How about the size of the elasticity?: Stretch by the object, extrusion and elastic deformation, the elastic solution is to look at the state of the object, at rest or in uniform linear motion of an object according to the stress analysis of the relationship between the force and other force, curve movement or acceleration force balance objects can analyze the stress in Newton's second law for, no matter what type of stretch can use the two methods to solve the hope to adopt: -)

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 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:What's the spring material to?: 65Mn, 55Si2Mn, 60Si2Mn, 50CrVA, 75, 85, 55CrMnA, 60Si2CrVA, 60Si2MnA, 70, 65, 50CrMo, 55SiMnMoVNb, 60SiMnMoA, 65Si2MnWA, 70Si3MnA, and so on

Q:What are the main functions of spring?: There are many kinds of spring, and the spring is mainly divided into four kinds: stretching spring, compression spring, torsion spring and bent spring. If in accordance with the spring shape and can be divided into helical springs, disc springs, ring spring, plate spring, spring etc.. The basic types of springs are listed in the table. Air springs.

Q:What's the manganese content of spring steel?: Refer to Baidu Encyclopedia: 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.

Our products are all kinds of springs including extension springs, compression springs, flat springs, seal springs, suspension springs, braking springs, spiral springs, belleville springs, mold-purpose springs, torsion springs, volute springs and waved springs.Especially,we are good at the large spring manufature,such as the locomotive springs. They are applied to a wide range of fields, such as automobile and motorcycle accessories, electronic instruments, coking plants, foundries, hydraulic pressure accessories, airproof accessories, electronic switches, elevators, air conditioners, medical instruments, engineering machinery, and colliery machinery. We can also customize our products according to customers' special requirements.
