German hagener springs hagener models hagener prices

hagener springs are a new type of elastic component that uses high-pressure nitrogen as the working medium. They feature compact size, high spring force, long stroke, smooth operation, precision manufacturing, long service life (one million cycles), flat force-deflection curve, and no need for pre-loading. They perform tasks that are difficult for conventional elastic components such as metal springs, rubber, and air cushions. They simplify mold design and manufacturing, facilitate mold installation and adjustment, extend mold service life, and ensure stable product quality. They can also be designed as a nitrogen spring system to operate as part of the mold, allowing constant pressure and delayed action to be easily achieved within the system. They are the next-generation ideal elastic components with flexible performance.

hagener Spring Introduction

Designed based on the principle of moment balance. Within the permissible load displacement, the load moment and the spring moment remain in balance. For pipes and equipment supported by constant-load hangers, a constant supporting force is provided during displacement, thus avoiding additional stress on the piping and equipment. Constant-load hangers are generally used where displacement stress needs to be reduced, such as suspended parts of power plant boiler bodies, steam, water, flue gas, and air ducts, and burners in power plants, as well as in the petroleum and chemical industries where such support is required. It is a mechanical part that works using elasticity. Parts made of elastic material deform under external force and return to their original shape after the force is removed. Also known as "spring". Generally made of spring steel. Springs come in various complex types; classified by shape, they mainly include helical springs, spiral springs, leaf springs, and special-shaped springs.

hagener Spring Structure and Principle

The torsion bar spring itself is a torsion bar made of spring steel. The cross-section of the torsion bar is usually circular, with a few being tubular or rectangular. The ends can be shaped as splines, square, hexagonal, or cylindrical with flats, so that one end is fixed to the vehicle frame and the other end is fixed to the suspension arm, which is connected to the wheel. One end of the torsion bar spring is connected and fixed to the frame, and the other end is connected to the wheel via the suspension arm. When the wheel encounters an obstacle on the ground and jumps upward, the wheel drives the suspension arm to rotate around the torsion bar axis by a certain angle, causing the torsion bar to undergo torsional deformation (elastic deformation). Meanwhile, the elastic potential energy stored in the torsional deformation of the torsion bar is released when the wheel leaves the obstacle, allowing the force transmission mechanism and the wheel to quickly return to position. During manufacturing, the torsion bar is pre-twisted to create a permanent torsional deformation, giving it a certain prestress. The direction of the applied pre-torsion is the same as the direction of torsion when the torsion bar operates on the vehicle, with the aim of reducing actual stress during operation and extending service life. Note that left and right torsion bars are not interchangeable.

hagener Spring Functions and Applications

1) Reset function: The spring deforms under external force and returns to its state after the force is removed. Many tools and devices use this property of springs for resetting. For example, reset springs are installed on the hinges of many building doors, allowing the door to automatically reset after people enter or exit. This function is also used to make products such as automatic umbrellas and mechanical pencils, which are very convenient. In addition, various buttons and keys require reset springs. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening the mainspring. When the mainspring is tightened, it bends and stores a certain amount of elastic potential energy. Upon release, the elastic potential energy is converted into kinetic energy, driving rotation through the transmission device. Toy guns, starting pistols, and military firearms also work using this property of springs. 3) Buffering function: Springs are installed between the locomotive or automobile frame and the wheels to use the elasticity of the springs to reduce vehicle bumpiness. 4) Vibration and sound generation function: When air flows through the reed holes in harmonicas and accordions, it impacts the reeds, causing them to vibrate and produce sound.
