German wenzl springs, wenzl models, wenzl prices

wenzl springs are helical springs that withstand compressive forces. The cross-section of the material used is mostly circular, but rectangular sections and multi-strand steel wires are also used. Springs generally have equal pitch. The shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of a compression spring. When subjected to external loads, the spring contracts and deforms, storing strain energy. Compression springs provide resistance to external compressive loads. Compression springs use multiple open coils to provide resistance to external loads (such as gravity pressing down on wheels, or body weight pressing on a mattress). In other words, they push back to resist external pressure. Compression springs are generally wound with metal wire at equal pitch and have a fixed wire diameter. In addition, there are conical compression springs, or springs combining conical and straight sections. Depending on the application area, compression springs can be used to resist pressure and/or store energy. Round wire is the most commonly used for compression springs, but compression springs are also made from square, rectangular, and specially shaped wire.

wenzl spring surface treatment

1) Blackening: This surface treatment provides a black surface. Blackening 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) Oiling: Oiling is the standard treatment for carbon steel springs, aimed at preventing 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 blackening. 6) Ultrasonic cleaning: This is the standard surface treatment for stainless steel materials. 7) Vibratory deburring: To remove sharp edges from the product.

wenzl spring materials

Disc springs are mostly manufactured from cold-rolled or hot-rolled strip steel, sheet metal, or forged blanks (forging ratio not less than 3). The materials commonly used are spring steels such as 60S2MA and 50CVA. For thicknesses less than 1.1, high-carbon steel can also be used. The performance requirements for disc spring materials are that, after heat treatment, they should have high ultimate strength, yield limit, elastic limit, and fatigue limit, while also requiring high impact toughness, plasticity, and the highest possible yield-to-tensile strength ratio. To meet these performance criteria, most domestic and international manufacturers use high-quality cold-rolled or hot-rolled steel strips or plates. For disc springs with a thickness greater than 6 millimeters, forged blanks are used, with the steel grades mainly being medium-carbon low-alloy spring steels (silicon-manganese or chromium-vanadium spring steels) and high-quality carbon spring steels. Due to the high silicon-manganese content and low chromium-vanadium availability in China, disc springs primarily use 60Si2MnA. Comparing the two, 50CrVA has better hardenability, temper stability, and impact toughness than 60Si2MnA, but 50CrVA is more expensive and suitable for applications with higher fatigue requirements.

wenzl spring manufacturing process

1) Cold forming process capability. Cold forming machines have developed up to 12 jaws. Wire in the range of (0.3–14) mm can be formed in one pass on an 8-jaw forming machine. Development directions for forming process equipment: (1)) Increase forming speed; the main trend is to improve the forming speed of the equipment, i.e., production efficiency; (2)) Improve equipment durability by enhancing the precision of equipment parts and strengthening heat treatment effects; (3)) Add length sensors and laser rangefinders to implement automatic closed-loop control of the manufacturing process for CNC forming machines. 2) Cold forming process range capability. Large wire diameter spring coiling machines have a maximum specification of 20mm, =2000MPa, winding ratio 5. Cold forming processes for variable-diameter or constant-diameter Minic-Block springs and eccentric springs still have limitations. 2) Hot forming process speed capability. In China, forming in the (9~25) mm specification range is limited to CNC2-axis hot coiling machines, with a maximum speed of 17 pieces per minute. There is a significant gap compared to developed countries. 2) Control capability for large spring hot forming processes. Due to the exclusive use of CNC2-axis hot coiling machines, shape control lacks action in three directions, resulting in poor precision; furthermore, there are no automatic bar rotation control and adjustment mechanisms, so the level and capability of hot coiled spring forming processes are relatively low. Consequently, the precision level and surface oxidation/decarburization level of the springs are also lower.
