German VIBRIX springs VIBRIX models VIBRIX prices

VIBRIX spring is a special type of extension spring, suitable for applications with large elongation and non-increasing load. Constant force springs consist of spiral metal strips; the inner side of the strip is curved so that each coil wraps tightly around the inner coil. When the metal strip is stretched (twisted), internal stress resists the load force, exactly like a standard extension spring, but the coefficient remains nearly constant (zero). See the load/torsion diagram. In use, an ID is typically used to wind this spring tightly onto a drum, with its free end connected to the load, acting like a counterweight. Alternatively, the free end can be fixed, allowing the spring itself to provide the working force, similar to carbon brushes in electrical devices.

VIBRIX Spring Features

1) High stiffness, strong buffering and vibration absorption capability, capable of bearing heavy loads with small deformation, suitable for applications with limited axial space. 2) Features variable stiffness characteristics, offering a wide range of nonlinear properties. 3) Using the same disc springs in different combinations allows spring characteristics to vary significantly. Combinations can be arranged in opposing or stacked configurations, or by combining different thicknesses and numbers of discs. 4) When stacked, for the same deformation, the greater the number of springs, the higher the load. 5) Short stroke, heavy load, compact space requirement, convenient combination, easy maintenance and replacement, economical, high safety, and long service life.

VIBRIX Spring Selection

A. Selection of spring force: Choose the quantity, model, and spring force of each gas spring based on the calculated punching force. Generally, the spring force should be selected by adding an increase of 15%-20% to the calculated punching force to better match actual conditions. First, mold wear leads to changes in clearance. Changes in process parameters such as blunt cutting edges, inconsistencies in mold thickness and sheet metal deformation resistance cause changes in workpiece deformation resistance, so design margins should be allowed. Second, during gas charging, high-pressure gas inevitably experiences throttling losses, causing a slight drop in spring force. Third, gas springs have a long service life, but after a period of use, high-pressure nitrogen leakage causes a slight decrease in spring force. B. Selection of gas spring quantity: Based on alignment requirements, combined with mold structure and force application points, ensure no eccentric loading occurs during mold operation, while facilitating mold adjustment. This ensures sufficient service life for the gas springs. C. Selection of gas spring boost ratio: Choose based on the gas spring characteristic curve and stamping process requirements to determine the gas spring model. Determining the boost ratio is particularly important when stable force change, basically constant working force, or high initial force is required. D. Selection of gas spring stroke: Regardless of the process, when selecting gas springs, keep the total height low to avoid instability and complex installation structures in the mold. Larger strokes result in higher gas spring prices, which is especially critical for independent gas springs. If a large stroke is technically necessary, it is recommended to use a gas spring seat plate system to reduce mold height and improve stability and reliability. For safety and to prevent accidents, add a 3-5mm safety stroke when selecting gas springs. Selection of gas spring structural form: When using gas springs in molds, designers must first decide on the structural form, comprehensively considering stamping process requirements, mold structure, equipment, working environment, working conditions, mold cost, and maintenance factors. A. Independent type: The most widely used is the independent gas spring, which occupies little mold space, is securely mounted, and offers various structural forms. Several different installation forms require no accessories and can be directly installed in the mold. It is the preferred design form for modern designers. B. Pipeline connection type: Pipeline connections are generally applied to large stamping parts and large coverings. High-pressure pipes connect individual gas springs, and a control instrument is installed to equalize the spring force across the system, integrating it into a single unit equivalent to an independent gas spring. This achieves greater spring force and balanced force transmission, extending mold life and ensuring stamping part quality.

VIBRIX Spring Compensation Method for Controlling Springback

The compensation method for controlling springback involves controlling the geometric shape and dimensions of the mold's working part based on the direction and magnitude of the bent part's springback, compensating for 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 compensates for springback deformation at the two corners by utilizing the deformation generated at the arc or inclined areas during unloading. Extending this, the bending compensation method can bend workpieces that are difficult to bend using conventional methods. For the shape shown in Figure 8, where both sides are tight with no forming space, bending can be achieved using deformation springback and correction compensation methods.
