The torsion spring:
Cylindrical torsion springs or also known as torsion springs, helical torsion springs are widely used and versatile machine elements components in the world of mechanics and spring technology.
The structure of a cylindrical torsion spring consists of a wire that is wound in a helical shape around a central axis in even turns.

torsion springs are used to absorb and release a rotating movement, a torque or a force and to guide the movement of the legs.
torsion springs are characterized by the ability to absorb and release deflections, forces or torques around a rotation axis and to guide the rotational movement.
torsion springs usually have a cylindrical spring body on which two legs are arranged.
The legs can be arranged tangentially, radially or axially, whereby each leg can have a different arrangement. Different spring end shapes can be attached to the end of the two legs, e.g. straight leg, hook shape, eyelet shape, round or square.
The terms "torsion spring", "torsion spring" and "torsion spring" refer to the same component.

The double torsion spring:
Double torsion springs, double torsion springs and double torsion springs are widely used and versatile machine elements in the world of mechanics and spring technology.
The structure of a double torsion spring consists of a wire that is wound in a helical shape in even turns to form two separate spring bodies. The two spring bodies are connected by a wire, which is usually designed as a U-shaped web.
The legs or spring ends of the double torsion springs are usually attached to the outside of the respective spring body. The force or torque is introduced either via the U-shaped web or via the legs. The double torsion spring is usually guided via a mandrel, axle or bolt.
Double torsion springs, double torsion springs and double torsion springs are used to absorb or release a rotating movement, torque or force. Double torsion springs are characterized by the ability to absorb or release deflections, forces or torques around a rotation axis.

The wire bent part:
In practical use, standardized wire bent parts such as spring rings, snap rings, retaining rings, clips, pins, etc. are found. A paper clip or a staple clip also belongs to the wire bent parts, wire form springs and bent parts.
However, in practical use, non-standardized, individual, application-specific designed wire bent parts are mostly used. Wire form springs and bent parts are used.
The focus is on the function of the component: e.g. securing, protecting, holding, positioning, clamping or springing.
Wire form springs, 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 made into a specific shape by bending wire and offer a variety of advantages in terms of flexibility, cost-effectiveness and functionality.
