German saueressig springs saueressig models saueressig prices

saueressig springs are energy accumulators; they store energy but cannot release it slowly. To achieve slow release, a "spring + high gear ratio mechanism" is required, commonly seen in mechanical watches. Helical springs have been applied since ancient times; bows and crossbows are two broad types of helical springs. By appearance, they can be divided into standard cylindrical helical springs and variable-diameter helical springs (see figure); by helix direction, they can be divided into left-hand springs and right-hand springs. Cylindrical helical springs have a simple structure, are easy to manufacture, and are the most widely used. Their characteristic curve is linear, and they can serve as compression springs, extension springs, and torsion springs. When the load is heavy and radial dimensions are limited, two compression springs with different diameters can be nested to form a combination spring. Variable-diameter helical springs include conical helical springs, volute helical springs, and concave helical springs. Conical helical springs offer good buffering performance and can withstand large loads. Volute helical 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 mostly used in cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular cross-sections being the most common.

saueressig spring classification

1) According to the characteristics of the load during operation, helical springs can be divided into compression, extension, and torsion types; 2) According to structural features, they can be divided into two main categories: cylindrical helical springs and variable-diameter helical springs; variable-diameter helical springs mainly bear compressive loads; 3) According to 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 appearance, they can be divided into: standard cylindrical helical springs; variable-diameter helical springs. By helix 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 the most widely used. Their characteristic curve is linear, and they can serve as compression springs, extension springs, and torsion springs. When the load is heavy and radial dimensions are limited, two compression springs with different diameters can be nested to form a combination spring.

saueressig spring features

1) Precise adjustment performance, meaning the relationship between force and displacement is highly sensitive; 2) Good flexibility, meaning the deformation range 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. Volute helical 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 mostly used in cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular cross-sections being the most common. A helical torsion spring is a spring that withstands torsional deformation, with its working part tightly wound into a helical shape. The ends of a torsion spring are processed into various shaped torque arms rather than hooks or loops. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production such as automobiles, machine tools, and electrical appliances.

saueressig 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 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 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 with no forming space. Using deformation springback and correction compensation methods, bending is possible.
