The difference between the special-shaped spring and the basic spring is that the spring itself is irregular, with bending and a lot of complicated perspective design. Suitable for some unique places.

Type of special-shaped spring

There are many types of special-shaped springs, which are described in detail as follows:

(1) Variable diameter spiral spring: it is used in some unique places, the material of variable diameter spring is generally circular section material, and most bear reduced load.

(2) sheet spring: This kind of spring material is spring with amorphous strip (or plate), in the professional equipment or universal working pressure processing equipment bedside, according to the corresponding mold manufacturing. Sheet spring, wave spring, light spring material thin thickness is thin, and small or medium-sized dish spring material thin thickness is usually thicker, the main use of this kind of spring is also very common.

(3) When the installation space is limited, the spring of rectangular frame section material is often selected, because the spring produced by rectangular frame section material can get a great load in the same space and the same shape variable. Compared with the spring of circular material, this kind of spring has a large cross-sectional area in the same space, so it has a large kinetic energy of digestion and absorption, as shown in the figure below. It can be used in heavy machinery equipment, hardware molds or springs with especially high bending stiffness.
