German lesch horn springs, lesch horn models, lesch horn prices

lesch horn springs are elastic elements with several peaks and valleys on a thin metal ring. They are typically used in applications where the load and deformation are small, requiring low spring stiffness and axial preload. Wave springs are particularly suitable for weight-sensitive applications and those constrained by limited installation space. Typical application areas include aerospace, precision machinery, hydraulic seals, and high-end motors. They are thin, ring-shaped elastic metal components composed of several peaks and valleys. The product uses high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), heat-treated using specific methods. Depending on the specific conditions, hardness is generally controlled between HRC44 and 55. The surface is blackened, providing good elasticity. Wave springs are widely used in motors, textile machinery, hydraulic equipment, automotive, and other industries. They are mainly installed in bearing housings or bores suitable for the nominal size. The installation space is very small, and they have special functions of reducing noise and vibration.

lesch horn spring installation and removal

Hydraulic hand pallet trucks are widely used in production. During maintenance of their pressure oil pumps, we found that the pressure spring responsible for returning the pump's piston rod and the truck's pressure arm to position has a wire diameter of n, with a stored elastic force reaching 1000N. This makes installation and removal very difficult, often delaying troubleshooting and directly affecting production progress. Previous measures taken were ineffective. Therefore, I designed the pressure spring installer/remover shown in Figure 1. The installer/remover consists of a lower pressing rod 1, pressure blocks 10, connecting pins 14, nuts 1, spherical washers 12, upper pressing rods 13, positioning sleeves 16, and other components. During operation, rotate the nut 11 to an appropriate position so that the cylindrical head claw of the lower pressing rod 1 contacts the vehicle body 2. The two pressure blocks 10 press symmetrically against the washer 6. Rotate the compression nut n to tighten the pull rod 15, causing relative movement between the upper pressing rod 13 and the lower pressing rod 1, thereby compressing the pressure spring. When the washer 6 separates from the cylindrical pin 7, the pressure roller shaft 9, pressure roller 8, and cylindrical pin 7 can be removed. Then, loosen the nut 11, remove the installer/remover, and take out the pressure spring to disassemble, inspect, and repair the pressure oil pump. The positioning sleeve 16 on the installer/remover is a key component. During manufacturing, one end features an internal spherical surface with a slot-shaped hole in the middle, while the other end is an inclined flat surface, forming an interference fit with the pressing rod. It must maintain good contact with the spherical washer 12 and the ball head of the rod 15. The pressure block 10 and connecting pin 14 have a clearance fit, requiring flexible rotation. The connecting pin 14 and upper pressing rod 13 have an interference fit. The connecting shaft 18 and pressing rod have a clearance fit.

lesch horn spring advantages and classification

The advantages of leaf springs include simple structure, reliable operation, low cost, and easy maintenance. They serve as both the elastic element of the suspension and the guiding device. One end is hinged to the frame, allowing transmission of various forces and moments, and determining the wheel runout trajectory. Additionally, they provide a certain degree of frictional damping. Offering three benefits in one, they are widely used in non-independent suspensions. Leaf springs are classified by shape: 1) Elliptical leaf springs; 2) Semi-elliptical leaf springs; 3) Quarter-elliptical leaf springs; 4) Single-leaf springs. Elliptical, semi-elliptical, and quarter-elliptical leaf springs are all composite types, relying on friction between leaves to provide high buffering and vibration damping performance. They are widely used in the suspension systems of automobiles, tractors, and railway vehicles. Single-leaf springs consist of a single piece of spring steel and are mostly used in mechanical equipment and instruments to clamp working components.

lesch horn spring compensation method for controlling springback

The compensation method for controlling springback involves controlling the geometric shape and dimensions of the die's working part 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 of the two corners. Extending this, the bending compensation method can 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.
