Types of Springs

According to the force nature, the spring can be divided into a tension spring, compression spring, the torsion spring and the bending spring, according to the shape, it can be divided into belleville spring, annular spring, plate spring, a coil spring, a spiral spring of a truncated cone, and the torsion bar spring, according to the production process, it can be divided into the cold coil springs and hot coil spring. The common cylindrical spring manufacturing is simple, and can be made into various types according to the load distribution, the structure is simple, and it is the most widely used. The materials of manufacture of the spring in general should have a high elastic limit, the fatigue limit, impact toughness and good heat treatment properties, the commonly used are carbon spring steel wire spring, alloy spring steel, stainless spring steels, and copper alloys, nickel alloy and rubber. Spring manufacturing method has the cold roll and hot roll methods.

Main Functions of the Spring
Spring has many categories, often, we can see ordinary spring in life, and the special springs used for special purposes. It is used to control the mechanical movement, such as the control in the internal combustion engine valve springs, clutch springs, etc. Absorb vibration and impact energy, such as automobiles, railway carriages under the buffer spring, the coupling of the vibration absorbing spring or the like. The storage and output energy is as a power, such as clocks spring firearms spring. Used as load cells, such as the dynamometer spring. The ratio of the load and deformation of the spring is called spring stiffness, the greater of stiffness, the harder the spring. Spring is widely used as a resilient element in the mechanical and electronic industries, the spring contained in the subject can produce a larger elastic deformation, mechanical work or the kinetic energy is converted to deformation energy, the deformation of the spring and after unloading disappeared. The deformation can be converted into mechanical power or kinetic energy.

Manufacturing Apparatus of Springs
Spring, as an important component of the industrial system, has a great amount of uses, but also has a wide range of types. So the spring production changes from original handmade, gradually moving towards automation manufacturing. Before ninety years ago in China, the spring industry only has a few professional production of spring machinery and equipment, as the spring market is growing, gradually the professional spring equipment companies also entered China, such as Taiwan's northeast spring mechanical (EN Overseas Chinese Ding), Mitsuhiro (KHM) gradually occupied the mainstream spring production market. Spring manufacturing equipment, the northeast of EN502 universal machine uses a proprietary mechanical, to conveniently and efficiently produce all kinds of springs and shape elastic elements. Currently, the domestic production of large spring CNC hot winding machine is still blank.
