14173258 Precision pin Excavator Bucket pin Suitable for SANY 375
Raw material preparation
Material selection: According to the use requirements and performance characteristics of the bucket shaft, select suitable high-strength alloy steel, bearing steel or alloy tool steel and other materials. Check the quality certification documents of the materials to ensure that the chemical composition, mechanical properties and other indicators of the materials meet the design requirements.
Cutting: According to the size specifications of the bucket shaft, use sawing machines, flame cutting machines or plasma cutting machines and other equipment to cut the raw materials into the required billet length. When cutting, the processing allowance should be considered to ensure that the subsequent processing can meet the dimensional accuracy requirements.
Machining
Rough machining: The forged bucket shaft blank undergoes rough machining processes such as rough turning and rough milling to remove most of the allowance and leave a machining allowance of 0.5mm-1mm for subsequent fine machining. Rough machining can improve processing efficiency and reduce processing costs.
Fine machining: The bucket shaft after rough machining undergoes semi-finishing turning, fine turning, grinding and other fine machining processes to ensure the dimensional accuracy and surface roughness of the bucket shaft. Use high-precision lathes, grinders and other equipment to strictly control processing parameters to ensure that the diameter tolerance, cylindricity, roundness and other indicators of the bucket shaft meet the design requirements.
Keyway and other feature processing: According to the design requirements, use milling machines, slotting machines or wire cutting machines to process keyways, oil holes, threads and other features on the bucket shaft.
Heat treatment
Quenching: Heat the machined bucket shaft to above the critical temperature, keep it warm for a certain period of time and then cool it quickly to make the material obtain martensitic structure and improve the hardness and strength of the bucket shaft. Parameters such as quenching heating temperature, holding time and cooling rate should be reasonably adjusted according to the material composition and the size specifications of the bucket shaft.
Tempering: The bucket shaft after quenching is tempered to eliminate quenching internal stress, stabilize the structure and size, and improve toughness. The tempering temperature is generally between 500℃-650℃. The specific tempering temperature and tempering time are determined according to the performance requirements of the bucket shaft.
Surface treatment
Anti-rust treatment: In order to prevent the bucket shaft from rusting during storage and use, it is treated with anti-rust. Common anti-rust treatment methods include electroplating, hot-dip galvanizing, phosphating, etc.
Lubrication treatment: In order to reduce the friction coefficient between the bucket shaft and other parts and improve the rotation flexibility and wear resistance, the bucket shaft surface is lubricated. Spraying lubricating oil, applying grease or surface chemical plating can be used to form a uniform lubricating film on the bucket shaft surface.
