German zimmermann springs, zimmermann models, zimmermann prices

zimmermann springs are a new type of elastic component that uses high-pressure nitrogen as the working medium. They feature compact size, high spring force, long stroke, smooth operation, precision manufacturing, long service life (one million cycles), a flat force-deflection curve, and no need for preloading. They perform tasks that conventional elastic components such as metal springs, rubber, and air cushions struggle to accomplish, simplifying mold design and manufacturing, facilitating mold installation and adjustment, extending mold service life, and ensuring stable product quality. They can also be configured as a nitrogen spring system to operate as part of the mold, enabling easy implementation of constant pressure and delayed action within the system, making them an ideal new-generation elastic component with flexible performance.

zimmermann spring classification

1) Based on the characteristics of the load during operation, helical springs can be divided into three types: compression, extension, and torsion; 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 primarily withstand compressive loads; 3) Based on shape characteristics, they can be divided into conical, spiral (volute), concave, and convex forms. 4) In terms of 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 typically 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 standard cylindrical helical springs and variable-diameter helical springs. By the direction of the helix, they can be divided into left-hand springs and right-hand springs. Variable-diameter helical springs include 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, allowing them to serve as compression, extension, and torsion springs. When the load is high and radial dimensions are limited, two compression springs with different diameters can be nested together to form a composite spring.

zimmermann spring composition

Ring springs are a type of compression spring composed of several inner and outer rings with tapered surfaces. Under axial load P, significant normal pressure is generated between the contact surfaces of the inner and outer rings, causing the inner ring diameter to decrease and the outer ring diameter to increase. Due to these changes in diameter, the spring shortens in length; when the external force is removed, since the taper angle b of the rings is greater than the friction angle, the spring returns to its original dimensions under elastic internal forces. When ring springs bear axial P, significant friction is generated between the tapered contact surfaces of the inner and outer rings, dissipating considerable energy, while the relationship between force and deformation remains linear. During loading, the external force P equals the sum of the spring's internal force and friction. ABO represents the unloading process, which includes two stages: the AB segment and the BO segment. The AB segment indicates the situation where the load decreases, and the spring's elastic internal force overcomes static friction, gradually restoring the spring to its original state. The inner and outer rings of ring springs are made from high-quality carbon steel or wear-resistant alloy steel. Each ring is first roll-formed to the required shape to enhance its load-bearing capacity, followed by heat treatment. Ring springs are heavy-duty springs with significant buffering and shock-absorption capabilities (the ratio of area OABO to OACO can reach 60～70%), and are commonly used in buffering devices for heavy vehicles, artillery, and aircraft landing gear.

zimmermann spring functions and applications

1) Reset function: The spring deforms under external force and returns to its original state once the force is removed. Many tools and devices utilize this property of springs for resetting. For example, reset springs are installed on the hinges of many building entrance doors, allowing the door to automatically return to its closed position after people pass through. This function is also used in products such as automatic umbrellas and mechanical pencils, offering great convenience. In addition, reset springs are essential components in various buttons and keys. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening the mainspring. When the mainspring is tightened, it undergoes bending deformation and stores a certain amount of elastic potential energy. Upon release, the elastic potential energy is converted into kinetic energy, driving rotation through the transmission mechanism. Toy guns, starting pistols, and military firearms also operate based on this property of springs. 3) Buffering function: Springs are installed between the frame and wheels of locomotives and automobiles, utilizing the elasticity of the springs to dampen vehicle vibrations and bumps. 4) Vibration and sound generation function: When air flows through the reed slots in harmonicas and accordions, it strikes the reeds, causing them to vibrate and produce sound.
