Bent wire parts, wire form springs and bent parts belong to the group of machine elements.
In practical applications, standardized bent wire parts such as spring rings, snap rings, retaining rings, clips, pins, etc. are found. A paper clip or a staple also belongs to the bent wire parts, wire form springs and bent parts.

However, in practical applications, non-standardized, individual, application-specific designed bent wire parts, wire form springs and bent parts are mostly used.
The focus is on the function of the component: e.g. securing, protecting, holding, positioning, clamping or springing.


Bent wire parts, wire form springs and bent parts as machine elements:

Bent wire parts, wire form springs and bent parts made of spring steel wire are important components in various industries and applications. Bent wire parts are special machine elements that usually have springy properties.
They are brought into a specific shape by bending wire and offer a variety of advantages in terms of flexibility, cost efficiency and functionality.


Technical functions of bent wire parts, wire form springs and bent parts:

  • Securing function (static)
  • Protection function (static)
  • Holding function (static)
  • Positioning function (static)
  • Clamping function (static)
  • Spring function with restoring force and restoring path (dynamic)


Properties of bent wire parts, wire form springs and bent parts:

One of the outstanding properties of bent wire parts is their flexibility.
Wire can be bent into almost any desired shape, be it a simple 2D geometry or a complex 3D structure. This enables technicians and engineers to design simple but also particularly complex components made of spring steel.
This means that these spring elements can be adapted precisely to the requirements of the specific application. The flexibility of bent wire parts opens up numerous possibilities for innovative solutions in many different industries.


Purpose of bent wire parts, wire form springs and bent parts:

The purpose of bent wire parts is to solve technical challenges and fulfill specific functions in various applications. They are used to fasten components, position machine elements, transmit forces, enable movements, restrict movements, create electrical contacts, stabilize structures and much more.


Design of bent wire parts, wire form springs and bent parts:

Bent wire parts, wire form springs and bent parts are spring components made of spring wire and, depending on the application, have differently designed bends.
The number of bends should be as small as possible and the bends should be in one plane. This and other kStructural design measures can be used to keep the requirements for production and material stress lower. For example, leg lengths or the length of the spring ends after a bend should not be less than a certain length [l(min) >= 5 x d].
In addition, the leg ends should not have any closed bends, e.g. in the case of eyelets.
The permissible wire bending radius is particularly important for wire form springs, which depends on the wire material used and the wire diameter. A practical and safe choice of bending radius is usually [r(bend) >= 2 * d]. Untempered spring wire steels [e.g. EN10270-1 (DIN 17223 T1)] can be produced with smaller bending radii [r(bend) >= 1 * d] than tempered spring wire steels (stainless steel wire) [e.g. EN10270-3 (DIN 17224)] [r(bend) >= 1.4 * d]. Bent wire parts and wire form springs are often manufactured with wire diameters in the range of 0.4mm to 5mm.


Manufacture of bent wire parts, wire form springs and bent parts:

Bent wire parts, wire form springs and bent parts are manufactured on so-called wire bending or wire winding machines. Depending on the diameter and material of the bent wire parts, these are processed using cold or hot forming. For smaller wire diameters (d <= 18mm), the wire bending parts, wire form springs and bent parts are manufactured on special CNC-controlled single-head or multi-head wire bending machines.
These CNC winding and bending centers for the production of two- and three-dimensional bent parts can be used in a versatile, flexible and economical way to achieve a wide variety of sizes, shapes and functions.
A well-known manufacturer of CNC winding and bending centers is WAFIOS AG in Reutlingen https://www.wafios.com/.
