>> Product Use

  • Connection function: Mainly used to connect the bucket and the dipper arm or other related parts of the Komatsu PC200/PC220 excavator, so that the bucket can form a stable connection structure with the dipper arm and other parts, ensuring that when the excavator is working, the bucket can perform corresponding excavation, loading and unloading operations with the movement of the dipper arm.

  • Transmit power and movement: During the working process of the excavator, the power is transmitted from the hydraulic system to the dipper arm and bucket. The pin can accurately transmit the movement and power of the dipper arm to the bucket, so that the bucket can perform excavation operations according to the predetermined trajectory and force, ensuring the accuracy and efficiency of the excavation action.

  • Bearing load: During the excavation process, the bucket will bear huge forces from materials such as soil and rocks, as well as its own gravity and inertia. The pin needs to bear and disperse these loads, and transmit them to the dipper arm and other structural components to ensure the stability and reliability of the entire working device.

>> Premium Materials for Durability and Strength

  • High-quality steel is usually used, such as 40Cr or 45# steel. 40Cr has good hardenability. After quenching and tempering, it can obtain high strength, high toughness and good wear resistance, and can better withstand the large alternating loads and impact forces that the pin shaft of the excavator is subjected to under complex working conditions. 45# steel has high strength and good cutting performance. After appropriate heat treatment, such as quenching and tempering, it can obtain good comprehensive mechanical properties, which can meet the requirements of the pin shaft to withstand certain loads and frequent movement friction during work.

  • Raw material preparation: Select suitable steel such as 40Cr or 45# steel, inspect the appearance, chemical composition and mechanical properties of the material, and cut the material with cutting equipment.

  • Forging processing: Heat the blank to the appropriate temperature, forge it with forging equipment, improve the internal structure, and then perform shaping.

  • Machining: First, rough machining to remove most of the excess, then fine machining such as fine turning and grinding, and finally drilling and milling.

  • Heat treatment: Quenching to obtain martensitic structure to improve hardness and strength, then tempering to eliminate internal stress and adjust performance.

  • Surface treatment: Nitriding or hard chrome plating can be performed to improve surface hardness, wear resistance and corrosion resistance.

  • Quality inspection: Dimensional accuracy, surface quality, hardness are tested, and internal defects are detected with flaw detection equipment.

  • Assembly and packaging: Clean qualified pins, assemble with related components, and then package according to needs.
