2343931 High quality excavator bucket pin for CAT 326/326
Material selection: According to the product design requirements, select suitable alloy structural steel materials, such as 40Cr, SCM440, etc., to ensure that the materials have good strength, toughness and wear resistance. At the same time, check the quality certification documents of the materials to ensure that the materials meet the standards.
Cutting: According to the design size, use cutting equipment (such as sawing machine, flame cutting machine, etc.) to cut the steel into the required length and specifications to provide blanks for subsequent processing. The cutting size should take into account the machining allowance to ensure the dimensional accuracy of the final product.
Rough machining: The forged bucket pin blank needs to be rough-machined. The blank is turned on a lathe to roughly machine the outer circle, end face and other basic shapes of the bucket pin, leaving a machining allowance of 0.5mm-1mm for subsequent fine machining.
Fine machining: The bucket pin after rough machining is fine-machined to further improve the dimensional accuracy and surface quality. The outer circle, end face, chamfer and other parts of the bucket pin are fine-turned on the lathe to make its size meet the design requirements. Then use a grinder to grind the outer cylindrical surface of the bucket pin to improve the surface finish and reduce the surface roughness.
Drilling: According to the design requirements of the bucket pin, determine the position of the drawing hole and other locations, and use a drilling machine for drilling. When drilling, the position accuracy and verticality of the hole must be ensured to ensure the performance of the bucket pin during installation and use.
Quenching: Quench the bucket pin after machining, heat the bucket pin to above the critical temperature, keep it warm for a certain period of time, and then cool it quickly to make the steel obtain martensitic structure and improve the hardness and strength of the bucket pin. Parameters such as quenching heating temperature, holding time and cooling speed need to be reasonably adjusted according to the material of the steel and the size of the bucket pin.
Tempering: There is a large internal stress inside the bucket pin after quenching, which is easy to cause cracking and deformation, so tempering treatment is required. Heat the bucket pin to a temperature range below the critical temperature, keep it warm for a certain period of time, and then slowly cool it to eliminate internal stress, stabilize the structure, and improve the toughness and dimensional stability of the bucket pin.
Hard chrome plating: In order to improve the wear resistance, corrosion resistance and surface finish of the bucket pin, the bucket pin is usually hard chrome plated. Before hard chrome plating, the bucket pin needs to be pre-treated by degreasing and rust removal to ensure the bonding strength of the chrome plating layer with the substrate. Then the bucket pin is placed in the chrome plating tank, and a hard chrome layer is deposited on the surface of the bucket pin through electrolysis. The thickness of the chrome plating layer is generally around 0.02mm-0.05mm.
Other treatments: In addition to hard chrome plating, other surface treatments can be performed on the bucket pin as needed, such as blackening treatment, phosphating treatment, etc., to improve the rust resistance and appearance quality of the bucket pin.
