Dongguan Fuda precision spring factory prompt you spring function:
1. Measurement function
We know that, within the elastic limit, the elongation (or contraction) of the spring is proportional to the external force. A spring scale is made by the nature of the spring.
2, tight pressure function
Observing all kinds of electrical switches, it is found that there must be a spring in the two contacts of the switch to ensure that two heads are in close contact and are well conducting. The torsion spring factory reminds you that if the contact is not good, the resistance at the contact point will increase. When the current passes, the heat will increase. If it is serious, it will also melt the metal at the contact point. The two metal posts of the bayonet lamp holder are also equipped with springs for contact. As for the core parts of the screw socket and the plug metal plates of all sockets, they are all reeds, whose functions are to keep the two sides close to maintain the same good. At the time of the tape, there is a piece of phosphorus bronze reed, which makes use of the elastic force produced by it to bend the head to contact the magnetic head with the tape. Shaped spring factory prompts you to stapler in a long spiral spring of the utility model is a top tight staples, on the other hand, when the front nail was launched, can be sent to the front behind the nail for nail comfortable launch, so will automatically be a push to nail first, until all the launch date nail. Many machine automatic feeding, automatic rifle bullets are loaded automatically by this function of the spring. In addition, a clip on a garment, a ball point pen, and a clip on the pen cover are clamped on the clothes by the tight pressure function of the spring.
3, reposition function
A compression spring spring factory prompts you to deform under the action of external force, the external force is removed, the spring will be able to restore the state. Many tools and devices are reset by the nature of the spring. For example, many of the gates of the building are installed with a reset spring and the door will be reset automatically. People also make use of this function to make automatic umbrellas and automatic pencils. It is very convenient. In addition, a variety of buttons and buttons can not be reset springs.
4, drive function
The stretch spring reminds you of the mechanical watch and the hair toy is driven by the tight bar. When the hair is tightened, the hair rod produces a bending deformation and stores a certain elastic potential energy. After the release, the elastic potential energy is transformed into kinetic energy, which drives the rotation through the transmission. Toy guns and firing guns and military guns also work with one of the properties of the spring.
5. Buffer function
A spring is fitted between the frame and the wheel of a locomotive, and the elasticity of the spring is used to slow the bump of the vehicle.
6. The function of vibratory sound
When the air flows from the reed hole in the harmonica and the accordion, the reed vibrate and the reed vibrate.
