German klinger federn springs, klinger federn models, klinger federn prices

klinger federn springs are conical disc-shaped. They can be used individually or in series or parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge. Upon compression, they deform until flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads. After deforming under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure in the flange connection to meet sealing requirements. The stress distribution of disc springs decreases uniformly from the inside out, achieving high compensation force with low travel.

klinger federn spring classification

1) Based on different load characteristics during operation, helical springs can be divided into compression, extension, and torsion types; 2) Based on structural features, they can be divided into two main categories: cylindrical helical springs and variable-diameter helical springs; variable-diameter helical springs mainly withstand compressive loads; 3) Based on shape features, they can be divided into conical, volute, concave, and convex shapes. 4) In production and use, helical springs can also be divided into large helical springs and small helical springs based on forming methods and material diameter; the former are usually hot-formed, while the latter are cold-formed. 5) Other classifications: There are many types of helical springs. By external shape, they can be divided into: ordinary cylindrical helical springs; variable-diameter helical springs. By spiral direction, they can be divided into: left-hand springs; right-hand springs. Variable-diameter helical springs are divided into: conical helical springs, volute helical springs, and concave helical springs. Cylindrical helical springs have a simple structure, are easy to manufacture, and are widely used. Their characteristic curve is linear, and they can serve as compression, extension, and torsion springs. When the load is large and radial dimensions are limited, two compression springs with different diameters can be nested together to form a combination spring.

klinger federn 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. Its ends can be shaped as splines, square, hexagonal, or cylindrical with flats, so that one end is fixed to the 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 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 torsional deformation (elastic deformation) of the torsion bar. Meanwhile, the elastic deformation energy stored by the torsional deformation of the torsion bar is released when the wheel leaves the obstacle, allowing the force transmission mechanism and the wheel to return to position quickly. During manufacturing, a permanent torsional deformation is pre-applied to the torsion bar to provide a certain prestress. The direction of the pre-applied torsion is the same as the direction of torsion when the torsion bar works on the vehicle, aiming to reduce actual stress during operation and extend service life. Note that left and right torsion bars are not interchangeable.

klinger federn spring compensation method for controlling springback

The compensation method for controlling springback controls the geometric shape and dimensions of the die working parts based on the direction and magnitude of the bent part's springback, compensating for the springback after bending. For example, for U-shaped parts with significant bending, the punch face or stripper plate surface can be made arc-shaped, or the punch and die can be made with inclined surfaces at a certain angle. Thus, the deformation generated at the arc or inclined areas during unloading can compensate for the springback deformation at the two corners. Extending this, the bending compensation method can bend workpieces that are difficult to bend using conventional methods. For the shape shown in Figure 8, the two sides are tightly closed with no forming space. Using deformation springback and correction compensation methods, bending is possible.
