German reifen casteel springs reifen casteel models reifen casteel prices

reifen casteel springs consist of tension springs and connecting springs. The pitch and helix direction of the tension springs and connecting springs are identical. A specialized fixture is used to clamp one end of the tension spring and screw it into the connecting spring. The other end of the tension spring is then rotated and fitted onto the other end of the connecting spring. Rotational force is used to screw the connecting spring into the interior of the tension spring, forming the tension spring into a ring spring. The utility model ring spring does not affect the shape and elasticity of the connection point, and the secure connection is applied in various situations requiring ring springs. A ring spring is composed of alternating stacked washer-like spring steel discs with inner conical and outer cylindrical surfaces, and washer-like spring steel discs with inner cylindrical and outer conical surfaces. The number of pairs of inner and outer rings in the ring spring is determined based on the magnitude of the load it bears and the deformation requirements. Ring springs are used in applications with limited space that require strong buffering.

reifen casteel spring features

1) High stiffness, strong buffering and vibration absorption capacity, capable of bearing large loads with small deformations, suitable for applications with limited axial space. 2) Features variable stiffness characteristics; this type of spring has a wide range of nonlinear characteristics. 3) Using the same disc springs in different combination methods allows the spring characteristics to vary over a wide range. Combination methods such as nested or stacked configurations can be adopted, as well as combinations with different thicknesses and different numbers of discs. 4) When stacked, for the same deformation, the greater the number of springs, the greater the load. 5) Short stroke, heavy load, small space requirement, convenient combined use, easy maintenance and replacement, economical, high safety, and long service life.

reifen casteel spring rebound control measures

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 magnitude of thickness tolerance of the blank, the surface quality, and the 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 large 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 radius of materials provided in references is mainly empirical data, which can serve as a reference for sheet metal designers when designing the bending radius of workpieces. 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 depth of the die opening 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-bending 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 out, thereby reducing springback (Figure 4). Therefore, adopting tensile bending processes and dies with adjustable clearance is very beneficial for controlling springback. 4) Design reasonable workpiece shapes: U-type bent parts have less springback than V-type parts. Complex workpiece shapes involve more mutual constraints between parts, making springback difficult to control. Therefore, ?-type springback is smaller than U-type. If suitable reinforcing ribs are pressed at the bending area, the springback will be even smaller. Therefore, flanging or hemming treatment of bent parts can not only improve stiffness but also reduce springback. 5) Adopt appropriate microstructural states: Materials after cold working hardening have large bending springback. For bent parts with high accuracy requirements where the blank has cold working hardening, annealing treatment should be performed before bending. Where necessary and permissible, heating bending should be adopted for workpieces with thicker blanks to eliminate springback. The springback angle of calibration bending is significantly smaller than that of free bending, and the greater the calibration force, the smaller the springback. 6) Calibrate the shape of the bending punch: This is because the calibration bending force concentrates the punching force in the bending deformation zone, forcing the inner layer of the metal 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 will be reduced, thereby achieving the goal of overcoming or reducing springback. Therefore, calibration bending is a bending method similar in nature to tensile bending, and its application range is broader. Generally, the shape shown in Figure 5 is mostly adopted for the calibration bending punch.

reifen casteel spring applications

To a large extent, disc springs are replacing cylindrical helical springs. They are commonly used in heavy machinery (such as presses) and weapons like cannons and aircraft as powerful buffering and vibration-damping springs, as clamping springs for automobile and tractor clutches and safety valves, and as energy storage elements for mobile devices. Disadvantage: Load deviation is difficult to guarantee. Disc springs can be divided into three categories based on their cross-sectional shape: standard disc springs (with rectangular cross-sections), disc springs with radial slots, and trapezoidal cross-section disc springs. Standard disc springs are divided into two types: with support surface and without support surface. Disc springs with radial slots are based on standard disc springs, with several uniformly distributed slots cut radially. The slots can be cut from the inner hole towards the outer circle, or from the outer circle towards the inner hole. Trapezoidal cross-section disc springs can be divided into two types: those with inner edge thickness greater than outer edge thickness, and those with inner edge thickness less than outer edge thickness. Since the deformation and load values of a single disc spring often cannot meet usage requirements, they can be used in groups to form disc spring assemblies (columns). Typical combination methods include: nested disc spring assemblies, composite disc spring assemblies, and other disc spring assemblies. Compared to cylindrical helical springs, disc springs have the following characteristics: 1) The load-deformation characteristic curve exhibits a nonlinear relationship. 2) Disc springs are thin and easy to form into assemblies, allowing for modular assembly and replacement, thus facilitating maintenance. 3) Disc springs with radial slots have zero-stiffness characteristics. This characteristic can be applied in situations where the spring force is required to remain basically stable within a certain deformation range. 4) The vibration absorption performance of disc springs is no lower than that of cylindrical helical springs. When using nested combinations, the friction between disc spring sheets provides significant damping, dissipating impact energy.
