Agricultural Machinery Spring S-shaped Card Spring 12 * 45 Agricultural Machinery Parts Agricultural Machinery Accessories Plow and Rake Spring
S-type spring (model: 12x45) is a metal elastic shock-absorbing accessory designed specifically for modern agricultural machinery, widely used in tillage machines, soil loosening machines, deep loosening machines, and tillage and land preparation machinery. As the core accessory connecting tillage components (such as shovel tips and gear rods) with the frame, it plays a key role in "flexible buffering" during soil tillage process with its unique "S" - shaped curve structure. This product provides excellent deformation recovery capability while ensuring soil rigidity through optimized geometric dimension design, which is an important guarantee for protecting large agricultural machinery from rigid impact damage under complex geological conditions.
Hardness index: The hardness of the working area is controlled between HRC 42-48, which ensures wear resistance and avoids the risk of fracture caused by excessive brittleness.
Surface treatment: using spray painting, spray painting or electrophoresis treatment, it has excellent rust and corrosion resistance, and can adapt to high humidity and high pH farmland soil environment
Product model/size: 12x45 (usually refers to a material cross-sectional width of 12mm, with specific installation length or angle parameters in accordance with the 45 series standards).
Material composition: 65Mn (65 manganese steel) or 60Si2Mn (silicon manganese spring steel) is used as the base material. These two materials are specialized steel grades for spring manufacturing, with extremely high elastic limits and fatigue resistance.
Heat treatment process: After precise quenching and tempering treatment, it ensures that the product obtains a uniform tempered martensite structure.
Imitation and obstacle avoidance ability: When encountering hard objects (such as rocks, tree roots) or undulating terrain during field operations, the S-shaped spring uses its elastic deformation to drive the shovel tip to automatically lift or retract, quickly resetting after bypassing obstacles. This "give and return" feature effectively reduces the risk of bending or breaking of the shovel teeth and frame due to impact
Soil fragmentation and vibration effects: Under high-speed operation, S-shaped springs will produce high-frequency and low amplitude elastic vibrations. This vibration is transmitted to the soil through the shovel tip, which can crush large soil blocks twice, while reducing soil adhesion and accumulation on the shovel tip, significantly reducing tillage resistance, and thus saving tractor fuel consumption.
High quality materials and long lifespan: Made of 65Mn/60Si2Mn alloy steel, it has undergone strict decarburization layer control and fatigue life testing. Under normal farming conditions, this spring can withstand tens of thousands of reciprocating bends without permanent deformation or fracture, and its service life far exceeds that of ordinary iron or untreated springs
