According to the nature of the force, metal spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into disc springs, ring springs, leaf springs, coil springs, cone scrolls
Folding squeeze function
Observe all kinds of electrical switches will find that the switch of the two contacts, there must be an outfit spring, to ensure that the two heads in close contact, is well-connected. If the contact is poor, the resistance at the contact becomes larger, the heat generated when the current passes becomes larger, and the metal melts at the contact point in severe cases. Bayonet lamp holder with two metal posts are also spring for good contact; as for the screw head of the center of the metal sheet metal sheet and all the socket are reed, its function is to make both sides in close contact to maintain to With good. When the tape, there is a piece of phosphorus bronze reed, the use of it flexural deformation elastic force generated when the head in close contact with the tape. In the stapler has a long spiral spring its role on the one hand is the top of the staple, on the other hand is when the front of the nail is pushed out, the back of the nail can be sent to the front to prepare for the launch of a comfortable nail, In this way, you can automatically push a nail to the front until the nail is fully launched. Many machines feed the material automatically. In addition, clips such as clothes clips, ball-point pens, and pen pockets grip the clothes with the squeezing function of the spring.
Folding drive function
Mechanical watches, clockwork toys are driven by the tight hair. When the winding is tightened winding produces bending deformation, storage of a certain elastic potential energy. Release, the elastic potential energy into kinetic energy, driven by the transmission device rotation.
Fold reset function
Spring under the action of external deformation occurs, remove the external force, the spring will be able to resume state. A lot of tools and equipment are the use of the nature of the spring to reset. For example, many buildings have hinge springs on their hinges that pop in and out, and the door automatically resets. People also use this feature made of automatic umbrellas, automatic pencil and other supplies, very convenient. In addition, a variety of buttons and buttons reset spring.
Fold buffer function
A spring is mounted between the frame of the locomotive and the wheel to ease the bumpiness of the vehicle by utilizing the elasticity of the spring.
Fold measurement function
We know that within the limits of elasticity, the spring's elongation (or contraction) is proportional to the external force. Spring balance made of this spring.
Vibration vocal function
When the air flows from the harmonica in the harmonica or the accordion, the impact reeds and the reeds vibrate to make a sound.
