What are the classification of hardware springs according to the nature of the force:
According to the nature of the force, hardware springs can be divided into tensile hardware springs, compression hardware springs, torsion hardware springs and bending hardware springs; according to their shapes, they can be divided into disc-shaped hardware springs, annular hardware springs, plate hardware springs, spiral hardware springs, and cut-off hardware springs. Cone scroll hardware spring and torsion bar hardware spring, etc.
Ordinary cylindrical hardware springs are the most widely used because they are simple to manufacture and can be made into various types according to the load conditions, with simple structure.
Generally speaking, the manufacturing materials of hardware springs should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Commonly used are carbon hardware spring steel, alloy hardware spring steel, stainless hardware spring steel and copper alloy, Nickel alloy and rubber, etc.
The manufacturing methods of hardware springs are cold-rolled and hot-rolled. Hardware spring wires with a diameter of less than 8 mm are generally cold-rolled, and those with a diameter greater than 8 mm are hot-rolled. Some hardware springs need to be forced or sprayed after they are made. Pill treatment can improve the load capacity of the hardware spring.
Compression hardware springs are helical hardware springs that accept downward pressure. Most of the materials used are circular in cross-section, and hardware springs made of rectangular and multi-stranded steel coils are generally equal-pitch compression hardware springs. The shapes are: cylindrical, Conical, convex and concave shapes, and a small amount of non-circular shapes.
There is a certain gap between the ring and the ring of the compression hardware spring. When subjected to an external load, the hardware spring shrinks and deforms and stores the deformation energy. What is a torsion hardware spring? The torsion hardware spring uses the principle of lever, through the softness and toughness of the material The distortion or rotation of the elastic material gives it great mechanical energy.
Tension hardware springs are spiral hardware springs that accept axial tension. Tension hardware springs are generally made of round cross-section materials. When not under load, the coils of the tension hardware springs are generally tight and there is no gap.
