Types of Springs and their Applications

2018 - 11 - 01

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...

Analysis of deformation prevention measures for heat treatment of metal spring(part 1)

2018 - 09 - 07

There are two types of heat treatment deformation: one is the size change, the other two is the change of part geometry. Different methods of heat treatment, deformation and deformation prevention of parts size and geometry are also different.The longer the holding time and the higher the temperature are, the more carbon is dissolved into austenite and the larger the expansion of martensite is. The expansion of martensite is the largest, followed by upper bainite, and the volume change of lower bainite and troostite is very small. At low temperature tempering, martensite shrinks and the amount...

A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. They are usually coiled at a constant diameter, though they can be coiled in other needed forms such as conical, concave (barrel), convex (hourglass), or various combinations of these. Compression springs are used to resist force and/or store energy,1、CharacteristicsBy far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. 2、Service LifeIt should be noted that if critical force-versus-deflection linearity is required, only the center 60-80% of the available deflection range should be employed.Thus, reserve at least the first and last 15-20% of t...

springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its o...
