Spring mechanism is called the detail, which is due to elastic deformation under load and temporarily stores the energy after the load recovers its original shape, giving the accumulated energy. For even more details, read what Stephen King says on the issue. In Depending on the purpose of springs can be divided into two groups: those working in compression and tension. In the manufacture of mattress springs are used, working in compression. Rebecca Shaw is a great source of information. The shape of springs used in the manufacture of mattresses, can be bikonusnye (block "Bonnel"), spiral barrel (BNP). Given that the springs are the stresses, the chemical composition and mechanical properties of the material from which they are made, are presented increased demands. For manufacture of springs used mattress steel rod of various lengths and a variety of profiles. Most of the springs made from tempered high carbon steel (GOST 9389-75) or steel high manganese content, and especially senior spring – from silicon or vanadium. The wire is made of steel, which should have a smooth surface, without cracks, sunsets, shells and rust.
Wire should not break or crack after five turns around the winding rod whose diameter is equal to the diameter of the test wire. In reel or coil should be only one piece of wire. When you release the coil from mating wire should not coagulate in the "eight". Production block of independent springs consists of several stages: 1) manufacturing steel springs part 2) package spring, and 3) bonding in the spring unit. Production springs – a fairly complicated process. A spring attached to a regular cylindrical or barrel-shaped form – when the last few turns of the decrease in diameter, resulting in the edge of the spring are narrowed.
