German Dopag springs, Dopag models, Dopag prices

Dopag springs consist of extension springs and connecting springs. The pitch and helix direction of the extension spring and the connecting spring are identical. A special fixture is used to clamp one end of the extension spring and screw it into the connecting spring. The other end of the extension 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 extension spring, forming a ring spring. This utility model ring spring does not affect the shape and elasticity of the connection area, and the secure connection is applied in various scenarios requiring ring springs. The ring spring is composed of alternating stacked washer-shaped spring steel discs with inner conical and outer cylindrical surfaces, and washer-shaped 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.

Dopag spring structure

The torsion bar spring itself is a torsion bar made of spring steel. The cross-section of the torsion bar is typically circular, with fewer instances being tubular or rectangular. Its ends can be shaped as splines, squares, hexagons, or cylindrical forms with flat surfaces, allowing one end to be fixed to the vehicle frame and the other end to be fixed to the suspension arm, which is connected to the wheel.

Dopag spring features

1) Precise adjustment performance, meaning the relationship between force and displacement is highly sensitive; 2) Good flexibility, meaning the range of deformation is relatively wide; 3) Relatively easy to manufacture; 4) Compact structure; 5) High energy utilization rate. Example characteristics: Conical helical springs offer good buffering performance and can withstand large loads. Spiral volute springs can store more energy and withstand larger loads, but the manufacturing process is more complex. The performance of concave helical springs is similar to that of conical helical springs, and they are often used in seat cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular cross-sections being the most common. Helical springs, also known as torsion springs, are springs that undergo torsional deformation, with their working part tightly wound into a helical shape. The end structure of a torsion spring is processed into torsion arms of various shapes, rather than hooks. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production sectors such as automotive, machine tools, and electrical appliances.

Dopag spring compensation method for controlling springback

The compensation method for controlling springback involves controlling the geometric shape and dimensions of the die's working parts based on the direction and magnitude of the bent part's springback, thereby 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. This allows the deformation generated at the arc or inclined areas during unloading to compensate for the springback deformation at the two corners. Extending from this, the bending compensation method can be used to bend workpieces that are difficult to bend using conventional methods. For the shape shown in Figure 8, the two sides are tightly closed, leaving no forming space. Using methods of deformation springback and correction compensation, bending can be achieved.
