German stabilus springs stabilus models stabilus prices

stabilus springs are elastic elements with multiple peaks and valleys on a thin metal ring. They are typically used in applications where the load and deformation are small, low spring stiffness is required, and axial preload must be applied. Wave springs are particularly suitable for weight-sensitive applications and those constrained by limited installation space. Typical application areas include aerospace, precision machinery, hydraulic seals, and high-end motors. They are thin, ring-shaped elastic metal components composed of multiple peaks and valleys. The product uses high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), heat-treated using specific methods. Depending on specific conditions, the hardness is generally controlled between HRC44 and 55. The surface is blackened, providing good elasticity. Wave springs are widely used in industries such as motors, textile machinery, hydraulic equipment, and automotive. They are mainly installed in bearing housings or bores suitable for their nominal dimensions. With minimal installation space, they offer special functions such as noise reduction and vibration damping.

stabilus Spring Introduction

Designed based on the principle of moment balance. Within the permissible load displacement, the load moment and spring moment always remain balanced. For pipes and equipment supported by constant-force hangers, a constant support force is provided during displacement, thus avoiding additional stress on the piping and equipment. Constant-force 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 in power plants, burners, and similar support requirements in the petroleum and chemical industries. 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, main types include helical springs, spiral springs, leaf springs, and special-shaped springs.

stabilus Spring Measures to Control Springback

1) Select materials with good bending performance: Using materials with a low yield limit and high elastic modulus as bending parts can achieve higher bending quality. In addition, the thickness tolerance of the blank, surface quality, and flatness have a significant impact on bending springback. For workpieces with high bending accuracy requirements, the quality of the blank in these aspects should also be screened. 2) Select a smaller relative bending radius: A small r/t value indicates a high degree of deformation. Generally, when r/t ≤ 3-5, it is considered that the bending zone of the sheet metal has fully entered the plastic state. A smaller bending radius is beneficial for reducing springback, but an excessively small bending radius may cause cracking in the bending zone. The minimum bending radii for materials provided in references are primarily empirical data and can serve as a reference for sheet metal designers when designing workpiece bending radii. 3) Select the required die clearance: For V type bending, the clearance value is achieved by high-speed machine tools and is independent of the die itself. For U type bending, springback decreases as the die opening depth increases, and springback decreases as the die clearance decreases. For workpieces with high bending accuracy, the single-side bending clearance can be set to Z = t; if higher bending accuracy is required, adopting bending with slight thinning is more effective in reducing springback. Because zero or negative clearance bending can change the stress state of the sheet metal, transforming ordinary bending into bending with tensile characteristics, creating a compressive stress state on the inner side of the neutral layer of the blank, so that the entire cross-section of the blank is in a tensile stress state in the tangential direction. After unloading, the springback of the inner and outer fibers cancels each other out, reducing springback (Figure 4). Therefore, adopting tensile bending processes and dies with adjustable clearance is highly beneficial for controlling springback. 4) Design reasonable workpiece shapes: U type bent parts exhibit less springback than V type parts. Complex workpiece shapes involve significant mutual constraint between parts, making springback difficult to control. Therefore, ? type springback is smaller than U type. If suitable stiffening ribs are pressed at the bending location, springback is further reduced. Therefore, flanging or hemming treatment of bent parts can both increase stiffness and reduce springback. 5) Adopt suitable microstructural states: Materials after cold working hardening exhibit large bending springback. For bent parts with high accuracy requirements where the blank has cold work hardening, annealing treatment should be performed before bending. Where necessary and permissible, heating the blank during bending should be adopted for thicker blanks to eliminate springback. The springback angle in calibration bending is significantly smaller than in free bending, and the greater the calibration force, the smaller the springback. 6) Calibrate the punch shape for bending: This is because the calibration bending force concentrates the punching force in the bending deformation zone, forcing the inner metal layer to be compressed. After the sheet metal is calibrated, both the inner and outer fibers are elongated and will shorten after unloading. Since the springback trends of the inner and outer layers are opposite, the amount of springback is reduced, thereby achieving the goal of overcoming or reducing springback. Thus, calibration bending is a bending method similar in nature to tensile bending, and its application range is broader. Generally, the punch for calibration bending mostly adopts the shape shown in Figure 5.

stabilus Spring Features

Suspensions using torsion bar springs have lighter mass, simpler structures, and do not require lubrication. By adjusting the installation angle of the fixed end of the torsion bar spring, automatic adjustment of vehicle body height is easily achieved. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared to helical springs, torsion bar springs are compact and easy to arrange. Torsion bar springs are widely used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs can be classified by cross-sectional shape into circular, tubular, and leaf types. Circular solid torsion bars have simple structures and are most commonly used. To assemble the torsion bar, its ends are machined into splines, hexagonal, square, etc. Due to the small size of the spline ends, spline connections are mostly used. Generally, the major diameter of the spline is 1.2 to 1.3 times the working diameter of the torsion bar, and the spline length is approximately 1.4 times the major diameter of the spline. As long as the crushing stress of the spline teeth is within permissible limits, the spline teeth should not be selected too long. Torsion bar springs generally use involute splines GB3478. In the JSB2705 standard, the recommended standard pressure angle for splines is 45°; modules are 1mm and 0.75mm. To facilitate the assembly of torsion bar springs, some designs make the spline diameters at both ends unequal or machine a blind tooth on the spline teeth at both ends.
