Detection of geometric size of 6.1 compression springs6.1.1 spring material diameter detection: check the spring material diameter generally with vernier caliper or micrometer. In particular, attention should be paid to the inspection of springs with small winding wires and annealed alloy wires wrapped by automatic spring coiling machines.6.1.2 spring free height or free length detection: the spring is generally placed in horizontal position measurement. It is allowed to be placed in erect position only when the self weight has no obvious effect on the height or length of the spring when it is...

A brief history of the development of Hooke's law

2018 - 08 - 09

At first, during the experiment, Hooke found that the weight added to the spring was proportional to the elongation of the spring, and he tested his conjectures by many experiments. In 1678, Hooke wrote a spring paper, which introduced the results of experiments on elastic objects, laying the foundation for the development of material mechanics and elastic mechanics.Spring dynamometerIn the early nineteenth Century, under the premise of a lot of experimental work in the former, British scientist Thomas Yang summed up the research results of Hooke and others, pointing out that if the elongation...

Types of Springs and their Applications

2018 - 08 - 21

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...

Surface treatment of stainless steel spring

2018 - 10 - 15

There are three ways to use stainless steel spring to remove oil and oxide skin:1. Immerse the stainless steel spring into the plastic container with the metal cleaning agent A diluted with water (the proportion of cleaning agent A and water dilution is 1:1 or 1:2), and the time should be as follows: the spring surface should be free from oil and oxide skin to restore the metal color. The soaking time should not be too long.So stainless steel spring surface has matte effect.2. In the ultrasonic equipment, the proportion of cleaning agent and water is about 1:30. It is advisable to restore the ...

Metal spring plays an important role in safety valve

2018 - 10 - 25

The spring relief valve is mainly composed of spool, seat, stem, spring and adjusting screw.The relief valve mainly USES spring force to press the spool on the seat.When the boiler pressure exceeds the pressure exerted by the spring on the upper part of the spool, the spool and stem are lifted and steam is discharged.When the boiler pressure is lower than the spring pressure acting on the upper part of the spool, the spool falls on the seat and the boiler stops discharging steam.The spool is a cone with a slight protrusion around the edge of the spool.When the steam opens the valve core, the e...

Daisy

Spring is a kind of elastic element widely used in the mechanical and electronic industries. Spring can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is transformed into mechanical work or kinetic energy.The ratio of load and deformation of the spring is called spring stiffness. There are many kinds of springs. They are used in various fields. According to the deformation condition, they can be divided into three kinds: spring, spring and spring.

Compression spring

compression spring (springs) is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful also rectangle and multi-strand steel rolled a travelling, spring is usually pitch, such as the shape of the compression spring are: cylindrical, conical, convex and concave and a small amount of noncircular, compression spring there is a certain gap between circle and circle, when under external load spring contraction deformation, deformation energy storage.

Tension spring

The tension spring (tension springs) is a spiral spring that bears the axial tension.When there is no load, the stretch spring is usually closed between the coil and the coil.It is widely used in machines and instruments to control the movement of the parts, to store energy and to measure the force.The hook is made of side hook spring, long hook spring, British hook spring, German type hook spring, half-circle hook spring, duck bill hook spring, etc.

Torsion spring

Torsion spring (torsion springs) have a great amount of mechanical energy by twisting or rotating a flexible material with a high degree of flexibility and toughness, using the lever principle.The working part of the spring, which is subjected to torsion and deformation, is also enclosed or separated by loops.The end structure of the torsion spring is made into various shape of torsion arm, which can be formed by the design.Torsion spring is often used in mechanical balancing mechanism, which is widely used in automobile, machine tool, electric appliance, etc.

compression spring, tension spring and torsion spring are the most common three springs, their shape and function are different

Constant Force Spring

2020 . 01 . 13

Constant force spring, or “clock” spring, is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant. Such applications as brush springs for motors, counterbalance springs for window sashes and carriage return springs for typewriters. Constant force motor springs are used to drive mechanisms for timers, movie cameras and cable retractors.Constant force spring also known as coil spring helix in a plane of the spring, Spring is the material wound into a plane of the spiral of a spring, the spring is fixed at one end, the other end of the material after acting torque bending torque, bending elastic deformation, so the spring in its own plane to p...

Compression Springs

2020 . 01 . 13

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...

When choosing the right spring, selecting the best spring wire is a critical before manufacturing. Below are some of the most common spring wire materials and their unique characteristics .Stainless Steel SpringsStainless steel springs have low-stress relaxation and resist corrosion. They have good strength at moderate temperatures and are resistant to heat. Extension springs are most commonly made from stainless steel.Extension springs absorb energy and provide resistance to pulling. As the name suggests, an extension spring stretches as a load is applied to it. Applications for extension springs include carburetors, trampolines and farm machinery.Oil Tempered Spring WireOil tempered wire is cold drawn and heat treated before plating. Ideal as a general purpose spring wire, it is often us...

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...
