Germany Stumpp+Schuele springs Stumpp+Schuele model Stumpp+Schuele price

Stumpp+Schuele spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It features compact size, high spring force, long stroke, smooth operation, precision manufacturing, long service life (one million cycles), flat force curve, and no need for pre-loading. It performs tasks that are difficult for conventional elastic components such as metal springs, rubber, and air cushions. It simplifies mold design and manufacturing, facilitates mold installation and adjustment, extends mold service life, ensures stable product quality, and can be designed as a nitrogen spring system to participate in operations as part of the mold. It allows easy implementation of constant pressure and delayed action within the system, making it an ideal new-generation elastic component with flexible performance.

Stumpp+Schuele spring applications

Steel wire compression springs are used in all types of applications, from home appliances to motorized equipment and motors, as they are the required spring type. Compressed by loads acting on them or their ends, compression springs are designed with compressed wires that attempt to return the spring to its original shape, thereby pushing back against the load. Main application areas: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, and engine valve springs.

Stumpp+Schuele spring features and functions

1) Wide stiffness range, strong buffering and vibration absorption capacity, and high deformation energy per unit volume of material. 2) Features variable stiffness characteristics. Stiffness can be corrected by changing the combination of wave peak height, width, and thickness. Stiffness can also be adjusted by varying the number of stacked discs. 3) Compared to disc springs, it offers advantages such as high strength, good flexibility, and strong impact resistance. 4) Compact structural dimensions; under the same theoretical parameters, it requires less installation space. Functions: (1)) Control mechanical motion, such as valve springs in internal combustion engines and control springs in clutches. (2)) Absorb vibration and impact energy, such as buffer springs under car and train carriages, and vibration-absorbing springs in couplings. (3)) Store and output energy as power, such as clock springs and springs in firearms. (4)) Serve as force-measuring elements, such as springs in force gauges and spring scales. The ratio of load to deformation in a spring is called spring stiffness; the greater the stiffness, the harder the spring. Springs are elastic elements widely used in the mechanical and electronics industries. When loaded, springs produce significant elastic deformation, converting mechanical work or kinetic energy into deformation energy. Upon unloading, the deformation disappears and the spring returns to its original state, converting deformation energy back into mechanical work or kinetic energy.

Stumpp+Schuele spring compensation method for controlling springback

The compensation method for controlling springback involves controlling the geometric shape and dimensions of the mold's working parts based on the direction and magnitude of the bent part's springback, so that the springback after bending is compensated. 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 can be achieved.
