What is the basic knowledge of medical spring? Du Shi Cheng Fa precision spring below to explain it to you!

A spring is a mechanical part that works by elasticity. Usually made of spring steel. Used to control the movement of parts, violent impact or vibration, energy storage, measuring the size of the force, etc., widely used in machinery, appearance.

Spring is just an accumulator, it has the function of storing energy, but can not gradually release energy, to end the gradual release of the function, should be the "spring + large transmission ratio arrangement" end, common in mechanical watches.

Springs are widely used in mechanical and electronic work. Spring can produce large elastic deformation under the action of stress and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring deformation disappears and returns to the initial state, and the deformation energy is converted into mechanical work or kinetic energy.

The ratio of spring load to deformation is called spring stiffness. The greater the stiffness, the stiffer the spring.

classification

According to the stress characteristics of the spring can be divided into: stretching spring, tensioning spring, replacement spring and bending spring.

According to the shape can be divided into: coil spring, disc spring, ring spring, waveform spring, flat spring, truncated conical coil spring, spring (coil spring), torsion bar spring, spring, special-shaped spring.

According to the manufacturing process can be divided into: cold coil spring and hot coil spring (wire diameter less than 8mm with cold coil method, more than 8mm with hot coil method).

According to the elastic component data, it can be divided into metal spring, rubber spring, polyurethane spring, hydraulic spring, gas spring, hydrogen bomb spring and so on.

According to the shape of the section of the spring wire can be divided into: round section spring and bending moment (square) section spring.

Spring maker

The main function of the spring

(1) Control mechanical movement, such as: internal combustion engine valve spring, clutch control spring, etc.

Absorb vibration and shock energy, such as: the car, the cushioning spring under the train car, the coupling spring in the absorption of vibration.

Store and output energy as power, such as wall clock springs, firearm springs, etc.

④ Used as force measuring element, such as force measuring device, spring spring balance, etc.

Metal spring manufacturing materials should generally have: high elastic limit, fatigue limit, impact toughness and excellent heat treatment function, commonly used are: carbon spring steel, alloy spring steel, stainless steel spring steel, non-ferrous metal alloy (copper alloy, nickel alloy).
