Excavator bucket bushing.
Connection and positioning
Precise connection: In the Komatsu PC200 excavator, the connection between the bucket and other parts needs to be highly precise. The bushing can ensure the precise connection between the bucket and related parts such as the I-frame, so that each part maintains the correct relative position during work, ensures the movement accuracy of the bucket, and helps to improve the accuracy and efficiency of the excavation operation.
Positioning function: Provide accurate positioning reference for the installation and operation of the bucket, prevent the bucket from offset or shaking during work, ensure that it performs excavation, loading and unloading operations in accordance with design requirements, and help improve the stability and controllability of the entire excavation operation.
Reduce friction and wear
Reduce friction loss: When the excavator is working, there is frequent relative movement between the bucket and the connecting parts, which will generate greater friction. The presence of the bushing can convert the direct metal friction between these parts into friction between the bushing and the parts. Since the bushing is usually made of materials with good friction reduction properties, it can effectively reduce the friction coefficient, reduce energy loss, and improve the working efficiency of the excavator.
Extend component life: By reducing friction, the bushing can significantly reduce the wear rate of various components in the bucket connection, extend the service life of the bucket, I-frame and other related connection components, reduce the number of repairs and replacements required due to component wear, reduce equipment maintenance costs, and increase the overall service life of the equipment.
Buffering and shock absorption
Absorb vibration energy: During excavation operations, the bucket will be subjected to various impact forces and vibrations, such as collisions with soil, rocks, etc. during excavation, and vibrations generated by the operation of the equipment itself. The bushing can act as a buffer, absorb and disperse these vibrations and impact energies, and reduce their impact on the bucket, I-frame and the entire excavator structure.
Protect equipment structure: Effectively buffer vibration and impact, help protect the excavator's frame, hydraulic system, electrical system and other components, avoid structural damage, loose parts, hydraulic pipeline rupture and other problems caused by long-term excessive vibration and impact, improve the reliability and stability of the equipment, ensure the normal operation of the equipment, and reduce the occurrence of failures.

Design and Modeling
Product Design: According to the parameters of the Komatsu PC200 excavator and the actual use requirements, determine the key parameters of the bushing, such as size, shape, and tolerance. The design should consider the bearing capacity, wear resistance, and sealing performance requirements of the bushing, and at the same time, combine the feasibility of the production process to ensure that the design can be produced efficiently and at low cost.
Build Model: Use computer-aided design (CAD) software to create a three-dimensional model of the bushing to intuitively display the appearance and internal structure of the product, so that the design team can conduct detailed inspection and optimization. Through simulation analysis, evaluate the performance of the bushing under different working conditions, such as stress distribution and deformation, and further improve the design.
Raw Material Preparation
Material Procurement: According to the design requirements, purchase suitable metal or non-metallic materials. For metal materials, such as copper alloys and alloy steels, ensure that the chemical composition and mechanical properties of the materials meet the standards; for non-metallic materials, such as engineering plastics and rubber, pay attention to their physical properties, aging resistance and other indicators.
Pretreatment: Necessary pretreatment is performed on the raw materials, such as cutting, forging, annealing, etc. of metal materials, to improve the processing performance of the materials and prepare for subsequent production processes; non-metallic materials may need to be dried, plasticized, etc. to ensure the stability of the materials during processing.
Molding Processing
Metal Bushing Molding
Casting: For some bushings with complex shapes, casting technology can be used. The molten metal liquid is poured into a pre-made mold, and the bushing blank is formed after cooling and solidification. Common casting methods include sand casting and precision casting. Precision casting can obtain higher dimensional accuracy and surface quality.
Forging: The metal blank is pressed by forging equipment to produce plastic deformation to form the required bushing shape. Forging can improve the internal structure of the metal, improve the strength and toughness of the bushing, and is suitable for bushings with higher performance requirements.
Machining: The bushing blank after casting or forging is finely processed using lathes, milling machines, drilling machines, grinders and other processing equipment to ensure that the dimensional accuracy and surface roughness of the bushing meet the design requirements. Processing includes internal and external circle processing, end surface processing, drilling, grooving, etc.
Surface treatment
Surface treatment of metal bushing
Phosphating: Phosphating can form a phosphate chemical conversion film on the metal surface to improve the corrosion resistance, lubricity and coating adhesion of the bushing. The phosphate film can also play a certain role in reducing friction and reducing the friction coefficient between the bushing and the mating parts.
Blackening: Blackening is to form a black oxide film on the metal surface, which is mainly used to improve the corrosion resistance and appearance quality of the metal, and can also improve the lubrication performance of the bushing to a certain extent.
Quality inspection
Dimensional accuracy inspection: Use measuring tools such as calipers, micrometers, three-coordinate measuring instruments, etc. to measure the various dimensions of the bushing to ensure that the dimensional deviation is within the tolerance range required by the design. Any dimension beyond the tolerance may affect the installation and use performance of the bushing, and needs to be adjusted or reworked in time.
Appearance quality inspection: Check whether there are cracks, sand holes, pores, missing materials, burrs and other defects on the surface of the bushing through visual inspection or with the help of optical instruments. Surface quality is directly related to the sealing and friction performance of the bushing. Bushings with appearance defects should be repaired or scrapped.
Hardness test: Use a hardness tester to test the hardness of the bushing to check whether the hardness of the material meets the design requirements. Hardness is an important indicator to measure the wear resistance and load-bearing capacity of the bushing. Unqualified hardness may cause premature wear or deformation of the bushing.
