11975455 Heavy duty pin Excavator Bucket pin Suitable for SANY 245
Raw material procurement: Select high-quality high-strength alloy steel that meets national standards and design requirements, and conduct strict quality inspections on the purchased steel, including appearance inspection, dimension measurement, chemical composition analysis and mechanical property testing, etc., to ensure that the quality of raw materials meets the standards.
Forging: Heat the qualified steel billets to the appropriate forging temperature range, use advanced die forging or free forging processes, and improve the internal structure of the steel through multiple upsetting, drawing and other operations to make it more dense and uniform, improve the overall performance, and forge the billets into a shape and size close to the bucket pin.
Rough processing: The forged billets are rough processed using lathes, drilling machines, milling machines and other equipment. Through turning, drilling, milling and other operations, most of the excess is removed to form the basic shape and structure of the bucket pin, leaving a suitable processing allowance for subsequent fine processing.
Heat treatment: The bucket pin after rough processing is subjected to heat treatment such as quenching and tempering. Quenching can greatly improve the hardness and strength of the pin. Tempering is used to eliminate the internal stress generated by quenching, stabilize the structure, adjust the balance between hardness and toughness, and make the bucket pin achieve ideal mechanical properties.
Finishing: The bucket pin after heat treatment is fine-processed by grinding machines and other precision processing equipment. The outer circle, inner hole, end face and other key parts of the bucket pin are ground to ensure that the dimensional accuracy and surface roughness meet the design requirements and ensure the matching accuracy with other parts.
Surface treatment: The bucket pin after finishing is subjected to surface treatment such as carburizing quenching or hard chrome plating. In special processing equipment, a uniform and dense hardened layer or chromium layer is formed on the surface of the bucket pin through chemical or electrolytic methods to improve its corrosion resistance and wear resistance.
Quality inspection: A variety of inspection methods are used to conduct comprehensive quality inspection of the bucket pin, and the dimensional accuracy is accurately inspected by measuring tools. The surface quality and internal structure are inspected by visual inspection, metallographic analysis, etc. The hardness is tested by a hardness tester, and non-destructive testing equipment is used for flaw detection to ensure that the product has no defects such as cracks.
Packaging and warehousing: bucket pins that pass the inspection are cleaned, oiled and protected, then packaged according to specifications and quantity, stored in the warehouse and awaiting shipment.
