>> Premium Materials for Durability and Strength

• High-quality carbon structural steel

• 45 steel: It is a medium carbon steel with high strength and hardness. After appropriate heat treatment, such as quenching and tempering (quenching + high temperature tempering), it can obtain good comprehensive mechanical properties, and the strength, toughness and wear resistance are well balanced. It can meet the use requirements of excavator bucket pins under general working conditions, and the cost is relatively low, and it is widely used.

• Alloy structural steel

• 40Cr: This is the most commonly used alloy structural steel with good hardenability. After quenching and tempering, it can obtain higher strength, toughness and fatigue resistance than 45 steel. It is used in excavator bucket pins and can withstand greater loads and impact forces. It is suitable for working conditions with relatively harsh working conditions and high requirements for component performance.

• 42CrMo: It is an ultra-high strength alloy structural steel with high strength, high toughness and good hardenability. Its comprehensive mechanical properties are better than 40Cr. It performs well in excavator bucket pin applications that bear heavy loads, high stresses and require good fatigue resistance, and can adapt to high-intensity operation requirements under extreme conditions such as mining.

• Bearing steel

• GCr15: is a commonly used high carbon chromium bearing steel with high hardness, wear resistance and contact fatigue strength, good dimensional stability and corrosion resistance. When used for excavator bucket pins, it can maintain good performance under high load and frequent friction working conditions, reduce wear and deformation, and extend service life. It is especially suitable for occasions with extremely high requirements for pin shaft precision and wear resistance.

• Raw material preparation

• Material selection: According to the performance requirements of the product, select suitable steel, such as 40Cr, 42CrMo and other alloy structural steel or GCr15 bearing steel, etc. Ensure that the raw materials have good chemical composition and mechanical properties and meet relevant standards and specifications.

• Inspection: Strict inspection of purchased steel, including appearance inspection, dimension measurement, chemical composition analysis, hardness test, etc., to ensure the quality of raw materials.

• Cutting: According to the size and weight requirements of the bucket pin, use cutting equipment (such as sawing machine, flame cutting machine, plasma cutting machine, etc.) to cut the steel into suitable blanks. When cutting, consider the processing allowance to ensure that subsequent processing can meet the dimensional accuracy requirements.

• Machining

• Rough machining: Rough machining of the forged blank, including turning the outer circle, end face, drilling, milling keyway and other processes, remove most of the allowance, and leave a processing allowance of 0.5mm-1mm for subsequent finishing. Rough machining can improve processing efficiency and reduce processing costs.

• Finishing: Use high-precision lathes, grinders, milling machines and other equipment for finishing to ensure that the dimensional accuracy and surface roughness of the bucket pin meet the design requirements. For example, cylindrical grinding can control the dimensional accuracy within ±0.01mm and the surface roughness reaches Ra0.8-Ra1.6μm.

• Thread processing: If the bucket pin has a threaded part, use a thread lathe or CNC machining center for thread processing to ensure the accuracy and quality of the thread.

• Pre-surface treatment processing: According to needs, some special processing may also be performed, such as knurling, chamfering, etc., to meet assembly and use requirements.

• Heat treatment

• Quenching: Heat the machined bucket pin to above the critical temperature, keep it warm for a certain period of time, and then cool it rapidly to make the steel obtain martensitic structure and improve hardness and strength. The quenching heating temperature is generally between 820℃-860℃, and the cooling medium can be selected from water, oil or other quenching media according to the material and performance requirements.

• Tempering: The bucket pin needs to be tempered after quenching to eliminate quenching stress, stabilize the structure and size, and improve toughness. The tempering temperature is usually between 550℃-650℃. The tempering time is determined according to the specific performance requirements, generally 1-3 hours.

• Surface quenching: For some bucket pins with high requirements for surface hardness and wear resistance, surface quenching treatment may also be performed, such as induction quenching, flame quenching, etc., so that the surface has high hardness and good wear resistance, while the core still maintains good toughness.

• Surface treatment

• Hard chrome plating: Hard chrome plating can form a hard, wear-resistant and corrosion-resistant chrome layer on the surface of the bucket pin, improve the surface hardness and finish, reduce the friction coefficient, and effectively prevent wear and corrosion. The thickness of the hard chrome plating layer is generally between 0.02mm-0.05mm.

• Blackening treatment: Blackening treatment is to form a black oxide film on the surface of the bucket pin, which mainly plays the role of rust prevention and beauty. The thickness of the oxide film is generally between 0.5μm-1.5μm.

• Phosphating treatment: Phosphating treatment can form a layer of phosphate chemical conversion film on the surface of the bucket pin, which can improve the corrosion resistance, wear resistance and lubricity of the parts, and is conducive to subsequent assembly and use. The thickness of the phosphating film is generally between 1μm-10μm.
