Function explanation of hardware spring

Metal spring is also known as metal spring. It is a mechanical part that uses elasticity to work. and has various functions.

Squeeze function

Observing various electrical switches, you will find that one of the two contacts of the switch must be equipped with a spring to ensure that the two contacts are in close contact and are well connected. If the contact is poor, the resistance at the contact will increase, and the heat generated when the current passes through will increase. In severe cases, the metal at the contact will melt. The two metal columns of the bayonet lamp holder are equipped with springs for good contact; as for the central metal sheet of the screw base and the socket metal sheets of all sockets are reeds, their function is to make the two sides in close contact to keep the Same as good. In the tape, there is a phosphor bronze reed, which uses the elastic force generated when it is bent and deformed to make the magnetic head in close contact with the tape. There is a long coil spring in the stapler. Its function is to hold the staples tightly on the one hand, and on the other hand, when the front staple is pushed out, the back staples can be sent to the front to prepare the staples to be pushed out comfortably. In this way, the nails can be automatically pushed to the front until all the nails are pushed out. Many machines automatically feed the material, and in addition, clips such as clothes clips, ballpoint pens, and clips on pen sleeves use the compression function of springs to clip on clothes.

Drive function

Mechanical clocks, clockwork toys are driven by winding the clockwork. When the spring is wound up, the spring is bent and deformed, storing a certain amount of elastic potential energy. After the release, the elastic potential energy is converted into kinetic energy, which is driven to rotate by the transmission device.

Reset function

The spring is deformed under the action of external force, and after the external force is removed, the spring can return to its state. Many tools and equipment use this property of springs to reset. For example, many building doors have return springs on the hinges that automatically reset when people enter or exit. People also use this function to make automatic umbrellas, automatic pencils and other supplies, which are very convenient. In addition, various buttons and keys are also indispensable for the return spring.
