>> Premium Materials for Durability and Strength

• Product material

• High-strength alloy steel: such as 40Cr, 42CrMo, etc. It has high strength, high toughness and good wear resistance. It can withstand the huge pressure and impact force of the rocker arm connecting arm when the excavator is working, ensuring reliability and stability under complex working conditions.

• Surface treatment material: In order to improve the corrosion resistance and wear resistance of the pin shaft, surface treatment is usually performed, such as hard chrome plating and blackening. Hard chrome plating can form a hard and smooth chrome layer on the surface of the pin shaft, which can not only improve wear resistance, but also effectively prevent corrosion; blackening treatment forms a black oxide film on the surface of the pin shaft, which plays a certain role in rust prevention and can also improve the appearance.

• Raw material preparation: Purchase high-strength alloy steel that meets the standards and conduct strict inspections on the steel, including chemical composition analysis, metallographic structure inspection, hardness test, etc.

• Forging: Heat the steel to a forging temperature range of 1050℃-1200℃, and use air hammers, friction presses and other equipment for forging. Through multiple upsetting and drawing processes, the internal structure of the steel is improved, and a blank close to the shape of the bushing is forged.

• Machining: Rough and fine machining, including turning, boring, grinding and other processes, to ensure the dimensional accuracy and surface quality of the pin shaft. The machining accuracy of key dimensions can be controlled within ±0.05mm, and threads, keyways and other connection structures are machined.

• Heat treatment: The processed pins are quenched and tempered at a quenching temperature of 850℃-900℃ and a tempering temperature of 550℃-650℃ to improve strength, hardness and toughness. Surface quenching processes such as induction heating quenching can also be used to improve surface hardness and wear resistance. The surface hardness can reach HRC50-HRC55.

• Surface treatment: Shot peening is performed to form compressive stress by high-speed projectiles hitting the pin surface to improve fatigue resistance. Surface treatment methods such as hard chrome plating and blackening are then selected to enhance corrosion resistance and appearance quality.

• Quality inspection and packaging: Comprehensive quality inspection is carried out, including dimensional accuracy, surface quality, hardness, metallographic structure, etc. Non-destructive testing technology is used to check whether there are defects such as cracks inside, and qualified products are packaged and put into storage.
