German mea protecc springs mea protecc models mea protecc prices

mea protecc springs are conical disc-shaped. They can be used individually or in series or parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge. Upon compression, they deform until flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads. After deforming under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure in the flange connection to meet sealing requirements. The stress distribution of disc springs decreases uniformly from the inside out, achieving high compensation force with low travel.

mea protecc spring surface treatment

1) Blackening: This surface treatment provides a black surface. Blackening prioritizes aesthetic appearance over corrosion resistance. 2) Chrome plating: Chrome plating is mainly used for carbon steel products, primarily to increase corrosion resistance. 3) Oil impregnation: Oil impregnation is the standard treatment for carbon steel products, 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 eliminate sharp edges on the product.

mea protecc spring features

1) Precise adjustment performance, meaning the relationship between force and displacement is highly sensitive; 2) Good flexibility, meaning a relatively wide deformation range; 3) Relatively easy manufacturing; 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 often 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 undergo torsional deformation. Their working part is also tightly wound into a helical shape. The end structure of torsion springs consists of torsion arms processed into 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.

mea protecc spring precautions

Due to product structure limitations, multi-strand springs generally feature high strength and good performance. The material must ensure final performance in terms of spring strength and toughness. During the processing of multi-strand springs, note the following: 1 Support coils can be cold-wound or hot-wound according to product requirements. When using hot winding, do not heat the spring until sparks fly or it turns white. The temperature for silicon-manganese steel must not exceed 850℃. Support coils and active coils must have effective contact, and the gap must not exceed 10% of the nominal inter-coil gap. 2 The characteristics of multi-strand springs can be determined by adjusting the lead. The pitch can be adjusted as necessary during winding. The pitch can be 3~14 times the wire diameter, but 8~13 times is generally preferred. Spring force is closely related to free height, closed ends, outer diameter, and wire properties, and can be changed by adjusting one or more of these parameters. 3 Springs without support coils and springs with very fine wire diameters should not have welded ends. However, the end strands must not be obviously loose and must be deburred. For multi-strand springs requiring welded heads, the welding length should be less than 3 times the strand diameter (maximum 10 mm). The heating length should be less than one coil. After welding, grind smooth. For gas welding, perform local low-temperature annealing on the welded area. 4 Spring surface treatment generally involves phosphating, but other treatments are also possible. If zinc or cadmium plating is applied, perform hydrogen embrittlement relief after electroplating. After hydrogen relief, conduct 3% retesting (no fewer than 3 pieces) for presetting. No fractures should occur during retesting. Remove surface dirt, salt marks, and oxide scale from springs using methods such as sand blasting or gasoline cleaning. Do not use acid cleaning. 5 Important springs should be compressed for 24 hours, and ordinary springs for 6 hours or compressed continuously 3~5 times, holding each time for 3~5 seconds. During compression, the gap between the spring and the mandrel should be 10% of the mandrel diameter. If the gap is too small, operation is difficult; if too large, the spring may bend and deform. If one spring breaks during compression, the rest must be reprocessed.
