German ERIKS springs ERIKS models ERIKS prices

ERIKS springs consist of extension springs and connecting springs. The pitch and helix direction of the extension springs and connecting springs are identical. A special fixture is used to clamp one end of the extension spring and screw it into the connecting spring. The other end of the extension spring is then rotated and fitted onto the other end of the connecting spring. Rotational force is used to screw the connecting spring into the interior of the extension spring, forming the extension spring into a ring spring. The utility model ring spring does not affect the shape and elasticity of the connection part, and the connection is secure, making it suitable for various applications requiring ring springs. The ring spring is composed of alternating stacked washer-shaped spring steel discs with inner conical and outer cylindrical surfaces and washer-shaped spring steel discs with inner cylindrical and outer conical surfaces. The number of pairs of inner and outer rings of the ring spring is determined based on the magnitude of the load it bears and the deformation requirements. Ring springs are applied in situations where space is limited and strong buffering is required.

ERIKS 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 piston rod and the truck's pressure arm is difficult to install and remove. Its wire diameter is n, and it stores an elastic force of up to 1000N, making installation and removal very difficult. This often delays troubleshooting and directly affects production progress. Previous measures taken were ineffective. Therefore, I designed a pressure spring installer/remover as shown in Figure 1. The installer/remover consists of a lower pressing rod 1, pressing blocks 10, connecting pins 14, nuts 1, spherical washers 12, upper pressing rods 13, positioning sleeves 16, and rods. During operation, rotate the nut 11 to the appropriate position so that the cylindrical head claw of the lower pressing rod 1 contacts the truck body 2. The two pressing blocks 10 press symmetrically on the washer 6. Rotate the compression nut n to pull the tie rod 15, causing the upper pressing rod 13 and lower pressing rod 1 to move relative to each other, 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 has an internal spherical surface with a slot hole in the middle, and the other end has an inclined flat surface. It fits with the pressing rod via an interference fit. It must make good contact with the spherical washer 12 and the ball head of the rod 15. The pressing block 10 and connecting pin 14 have a clearance fit to ensure 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.

ERIKS spring features

1) Precise adjustment performance. That is, the relationship between force and displacement is very 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 have good buffering performance and can withstand large loads. Spiral volute 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 seat cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular cross-sections being the most common. Helical springs, also known as torsion springs, are springs that withstand torsional deformation. Their working part is also tightly wound into a helical shape. The end structure of torsion springs is processed into torsion arms of various shapes, rather than hooks. 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.

ERIKS spring compensation method for controlling springback

The compensation method for controlling springback involves controlling the geometric shape and dimensions of the working part of the die based on the direction and magnitude of the springback of the bent part, so that the springback after bending the workpiece is compensated. For example, for U-shaped parts with significant bending, the end face of the punch or the surface of the stripper plate can be made arcuate, or the punch and die can be made with inclined surfaces at a certain angle. Thus, the deformation generated at the arcuate or inclined areas during unloading can compensate for the springback deformation of 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, both sides are tightly closed, leaving no forming space. Using the method of deformation springback and correction compensation, bending is possible.
