>> Premium Materials for Durability and Strength

• High-Strength Alloy Steel: Usually, high-strength alloy steels like 4140 are adopted3. Alloy steel has excellent comprehensive mechanical properties, including high strength, good toughness, and strong wear and fatigue resistance. It can endure the large forces and complex stresses that occur during the excavator's operation, ensuring the pin's service life and reliability.

• Raw Material Procurement: High-quality alloy steel materials that meet the design requirements are selected. The materials should have stable chemical composition and excellent mechanical properties. The purchased steel is inspected for quality, including checking its appearance, dimensions, and performing chemical composition analysis and mechanical property tests.

• Forging: The steel is heated to an appropriate forging temperature range and then forged using forging equipment. Through processes like upsetting and stretching, the internal structure of the steel is refined, improving its density and mechanical properties. The steel is forged into a rough shape close to that of the pin.

• Machining: The forged blank undergoes rough machining first, including turning, drilling, and milling to remove most of the excess material and form the basic shape of the pin. Then, finish machining is carried out using grinding and other processes to ensure that the pin's dimensions, surface roughness, and other technical requirements are met. During machining, key structures such as grooves and holes are processed as required.

• Heat Treatment: The machined pin is quenched and tempered. Quenching can improve the pin's hardness and strength, while tempering is used to eliminate internal stress, stabilize the structure, and improve the pin's toughness, achieving a balance between hardness and toughness to meet the actual use requirements.

• Surface Treatment: After heat treatment, the pin is subjected to surface treatment such as zinc plating or phosphating to improve its corrosion resistance and wear resistance. This can effectively extend the pin's service life in harsh working environments.
