Elastic yellow is a kind of mechanical parts that use malleability to work. Generally made of tool steel, used to control parts of the fitness movement, to mitigate impact or vibration, storage of kinetic energy, force measurement, etc., widely used in equipment, instrument panel. Customized compression die elastic yellow types are complex and varied, according to the appearance of the key compression spring, vortex spring, etc. The following three and spring manufacturers introduce the key role of elastic yellow:

(1) Exercise to control mechanical equipment, such as valve springs in gas turbines, control elastic yellow in clutch, etc.

(2) Digestion and absorption of shock and impact kinetic energy, such as the cache elastic yellow under cars and high-speed rail cars, vibration absorbing elastic yellow in the shaft connecting device, etc.

(3) Storage and output kinetic energy as a driving force, such as clock shot yellow, gun shot yellow, etc.

④ as force measuring components, such as force measuring instrument, spring balance in the yellow. The greater the bending stiffness, the stiffer the elastic yellow is.

Elastic yellow is a kind of vibration isolator widely used in mechanical equipment and electronics industry. Elastic yellow will cause great elastic deformation when it is loaded, converting mechanical energy or mechanical energy into deformation energy. After unloading, the deformation of elastic yellow will subside and respond to the original appearance, converting deformation energy into mechanical energy

1, measurement effect

We know that, within the elastic limit, the elastic yellow extension (or retraction) is positively correlated with the external force. The spring scale is made of spring yellow.

2, pressing effect

Look at a variety of electrical switches will find that the power switch of the 2 circuit breakers, there must be around one with elastic yellow, to ensure that the 2 inseparable contact, is good on and off. If the contact is bad, the resistor at the contact increases, and the current flow increases according to the heat generated when it is more serious, it will continue to dissolve the metal material at the contact. The two metal columns of the interface light port are equipped with elastic yellow for better touch; The copper sheet of the management center of the spiral lamp port and the copper sheet of the lamp wire of all the power sockets are customized tensile springs, whose function is to make each other inseparable contact, in order to maintain to the same good. In cassettes, a tin bronze reed is used to make deep contact with the tape by bending and deforming. There is a long compression spring in the stapler. Its function is on the one hand to tighten the stapler. On the other hand, when the front nail is released, it can send the back nail to the front so that the nail can be released comfortably, so that it can automatically push one nail to the front until all the nails are released. Many devices are fully automatic feed, sniper rifle shells are fully loaded by this function. In addition, such as clip clothes pants iron clip, ball pen core, pen sleeve clip on the use of elastic yellow clamping effect on the clothes.

3. Calibration effect

The elastic yellow deforms under the external force. After removing the external force, the elastic yellow can be repaired by customized torsion mold. Many special tools and machines are calibrated using this property. For example, many houses have calibration bullets installed on the hinges at the gate of the building. After everyone comes in and out, the door will be automatically calibrated. We also use this function to make automatic umbrella, automatic pencil and other utensils, very convenient. In addition, a variety of keys and function keys are also unavoidable calibration.

4. Promoting effect

Mechanical equipment clocks, clockwork toys are all driven by twisting accessories. When the fitting is tightened, it causes bending deformation and stores certain elastic potential energy. When released, the elastic potential energy changes to mechanical energy and rotates according to the gear drive. In toy guns and starting guns and military firearms are also one of the characteristics of the use of elastic yellow work.

5. Cache function

It is equipped with elastic yellow between the window frame and the wheel of the electric locomotive car, and its ductility is used to alleviate the shaking of the car.

6. The effect of pronunciation

When the gas flows through the reed holes in the harmonica and electronic organ, the reed vibrates and makes a sound.
