German Kuka springs Kuka models Kuka prices

Kuka springs consist of extension springs and connecting springs. The pitch and helix direction of the extension spring and the connecting spring 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 a ring spring. This utility model ring spring does not affect the shape and elasticity of the connection point and provides a secure connection 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 inner and outer ring pairs in the ring spring is determined based on the magnitude of the load it bears and the deformation requirements. Ring springs are applied in spaces with limited room where strong buffering is required.

Kuka spring surface treatment

1) Black oxide treatment: This surface treatment provides a black surface; black oxide is primarily for aesthetic improvement rather than corrosion resistance. 2) Chrome plating: Chrome plating is mainly used for carbon steel products, primarily to increase corrosion resistance. 3) Oil immersion: Oil immersion is the standard treatment for carbon steel parts, intended to prevent rust during transportation and storage. 4) Passivation: Passivation is a cleaning method for stainless steel materials. 5) Phosphate coating: Phosphating offers better corrosion resistance than black oxide. 6) Ultrasonic cleaning: This is the standard surface treatment for stainless steel. 7) Vibratory deburring: To remove sharp edges from the product.

Kuka spring selection

A. Selection of spring force: Select the quantity, model, and spring force of each gas spring based on the calculated punching force. Generally, the spring force of the gas spring should be selected by adding an increment of 15% to 20% to the calculated punching force, which better reflects actual conditions. First, as the die wears, gaps change. Changes in process parameters such as blunt cutting edges, inconsistencies in die thickness and sheet metal deformation resistance, cause changes in workpiece deformation resistance, so allowance should be made in the design. Second, during charging, high-pressure gas inevitably experiences throttling losses, causing a slight drop in spring force. Third, gas springs have a long service life; after a period of use, high-pressure nitrogen leakage causes a slight decrease in spring force. B. Selection of the number of gas springs: Based on alignment requirements, combined with the die structure and the position of force application points, ensure no eccentric loading occurs during die operation, while also facilitating die adjustment. This ensures sufficient service life for the gas springs. C. Selection of the gas spring boost ratio: Select based on the gas spring characteristic curve and stamping process requirements to determine the gas spring model. Determining the boost ratio is particularly important when stable force change, basically constant working force, or high initial force is required. D. Selection of gas spring stroke: Regardless of the process, when selecting gas springs, keep the total height low to avoid instability and overly complex installation structures in the die. Larger strokes result in higher gas spring prices, which is especially important for independent gas springs. If a large stroke is required by the process, it is recommended to use a gas spring seat plate system to reduce die height and improve stability and reliability. For safety and to avoid accidents, increase the safety stroke by 3-5mm when selecting gas springs. Selection of gas spring structural form: When using gas springs in dies, designers must first decide on the structural form, comprehensively considering stamping process requirements, die structure, equipment, working environment, working conditions, die cost, and adjustment/maintenance factors. A. Independent type: Independent gas springs are the most widely used. They occupy less die space, are securely mounted, and come in various structural forms. Several different installation forms require no accessories and can be directly installed in the die. This is the preferred design form for contemporary designers. B. Pipe-connected type: Pipe-connected types are generally applied to large stamping parts and large coverings. High-pressure pipes connect individual gas springs, and a control instrument is installed to equalize the spring force of all gas springs in the system, integrating the entire system into one equivalent independent gas spring. This achieves greater spring force and balance in force transmission, extending die life and ensuring stamped part quality.

Kuka spring features

Suspensions using torsion bar springs are lighter in weight, have a simpler structure, and do not require lubrication. Vehicle height automatic adjustment is easily achieved by adjusting the installation angle of the torsion bar spring's fixed end. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared to coil springs, torsion bar springs are compact and easier to arrange. Torsion bar springs are widely used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs are classified by cross-sectional shape into circular, tubular, and leaf types. Circular solid torsion bars have a simple structure and are the most commonly used. To assemble the torsion bar, its ends are machined into splines, hexagonal, square, etc. Due to the small size of the spline ends, spline connections are mostly used. Generally, the major diameter of the spline is 1.2 to 1.3 times the working diameter of the torsion bar, and the spline length is approximately 1.4 times the spline major diameter. As long as the compressive stress on the spline teeth is within permissible limits, the spline teeth should not be excessively long. Torsion bar springs generally use involute splines GB3478. In the JSB2705 standard, the recommended standard pressure angle for splines is 45°; modules are 1mm and 0.75mm. To facilitate torsion bar spring assembly, some torsion bars have unequal diameters at the spline ends or a blind tooth machined on the spline teeth at both ends.
