Wire forming spring is a mechanical part that uses elasticity to work. It is usually made of spring steel. It is used to control the movement of machine parts, to mitigate impact or vibration, to store energy and to measure the magnitude of force. It is widely used in machines and instruments.The spring is just an accumulator. It has the function of storing energy, but it can not release the energy slowly. To realize the function of releasing slowly, it should be realized by "Spring + large transmission ratio mechanism", which is common in the mechanical meter.Spring is a kind of ela...

Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment, take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy—think of them as analogous to batteries! The earliest spring-driven clocks appeared in the 1400s. Fast-forward some 600 years, you still have to charge the Apple Watch everyday, and it’s not nearly as fast as winding a clock…but I digress.My personal fascination with springs began with Slinkies and wind-up toys, and countless mechanical pencils were sac...

Detection of the characteristics of 7.2 torsion springsWhen measuring torque, the size of the torsional spring axis must be suitable. The inner diameter of the spring should be kept to a certain gap, and the friction force and friction torque caused by the contraction of the inner diameter of the spring should be avoided, and the measurement accuracy should be affected. But the spindle can not be too small, otherwise it will cause the offset between the external torque and the measuring torque center, resulting in the error of the torque measurement. The specific testing program for torsion sp...

1. Shape effect is mainly caused by design factors, such as small fillet R, inappropriate location of acupoints, poor cross-sectional transition. 2. Overheating (overheating) is mainly caused by improper temperature control or running temperature, excessive process setting temperature, uneven furnace temperature and other factors. Preventive measures include overhaul, calibration of temperature control system, correction of process temperature, the addition of pad iron between the workpiece and furnace floor, etc.3. Decarbonization is mainly caused by overheating (or overburning), unprote...

For a long time, the shape and performance of the extension spring will change. If the extension spring is always in a certain situation, it may change its quality due to external conditions.Generally, there are the following situations:I. wear of extension spring :Wear can be divided into abrasive, fatigue and corrosion wear fracture.Ii. Brittle fractureThe majority of spring break belongs to brittle fracture.Plastic fracture is possible only when the working temperature is high.In engineering, fatigue fracture, stress corrosion fracture and hydrogen embrittlement fracture are called brittle ...

(4) the development of stainless steelChina is a big country in the production of stainless steel. With the production and development of stainless steel, many varieties have been developed naturally. At present, more than 50 kinds of stainless steel have been developed, which basically meet the needs of domestic production and development, and a brief description of some new varieties developed at present.1) the initial formation of austenitic stainless steel system. Low carbon austenitic stainless steel 0Cr18Ni9 and 00Cr17Ni2Mo2 have been developed to eliminate fatigue corrosion caused by ca...

Like most other basic mechanisms, metal springs have existed for a long time in the bronze age. Even for metals, wood is used as a structural member of flexible bow and arrow and military catapult. In the Renaissance, precise clocks made precision springs the first necessity. In Fourteenth Century, we saw the precise clock of revolutionary astronomical navigation developed. The world's exploration and conquest of European colonial powers continue to provide impetus for watchmakers "science and art." The other area of the firearm promotes the development of the spring. At the dawn...

The spring should ideally conform to hooke's law, that is, the relationship between stress and strain in the elastic range is linear.However, since the actual spring steel is a polyphase and polycrystalline material, there must be inconsistencies in composition, structure, elasticity, etc., and the stress and strain deviated from the linear relationship within the elastic range, which is called elastic incompleteness or anelastic.The phenomena such as elastic after effect, elastic lag, stress relaxation and elastic modulus decrease are produced.After tempering, the stabilization process ca...
