Metal material

40Cr steel: It is a medium carbon tempered steel with good comprehensive mechanical properties. After tempering, it can obtain higher strength and toughness, and has good wear resistance. It is used for bucket bushings, which can withstand the greater pressure and friction of the bucket during excavation operations, ensuring the service life and performance stability of the bushing.

Raw material preparation

Material procurement: According to the design requirements, purchase suitable metal materials, such as selected copper alloys or alloy steels, to ensure that the chemical composition, mechanical properties, etc. of the materials meet the standard requirements.

Material inspection: Strict inspection of the purchased raw materials, including chemical composition analysis, hardness test, tensile test, etc., to ensure the quality of the materials.

Pretreatment: Cut the raw materials and process them into billet sizes suitable for subsequent processing. At the same time, clean, degrease, derust and other treatments are carried out to remove surface dirt, oil and rust to provide good surface conditions for subsequent processing.

Machining: Use lathes, milling machines, drilling machines, grinders and other machining equipment to perform precision machining on the bushing blanks after casting or forging. Including machining the inner and outer diameters, lengths, oil grooves, oil holes and other dimensions and structures of the bushing to ensure the accuracy and surface quality of the bushing so that it meets the design requirements.

Heat treatment and surface treatment

Heat treatment: Heat treatment of the machined bushing, such as quenching, tempering, normalizing, etc. Through the control of heating and cooling, the organizational structure of the material is adjusted, the internal stress is eliminated, and the hardness, strength, wear resistance and toughness of the bushing are improved to meet the use requirements.

Surface treatment: In order to improve the corrosion resistance, wear resistance and friction reduction performance of the bushing, the bushing after heat treatment is subjected to surface treatment, such as electroplating, spraying, phosphating, etc.

Quality inspection and packaging

Quality inspection: A variety of testing methods are used to conduct a comprehensive inspection of the bushing. Use measuring tools (such as calipers, micrometers, three-coordinate measuring machines, etc.) to detect the dimensional accuracy of the bushing; use a hardness tester to detect the hardness; use flaw detection equipment (such as ultrasonic flaw detectors, magnetic particle flaw detectors, etc.) to check whether there are defects inside; for bushings with sealing requirements, sealing performance tests are also required to ensure that the product meets quality standards.

Cleaning and packaging: Clean the bushings that have passed the inspection to remove impurities such as oil stains and iron filings on the surface, and then apply oil protection to prevent rust during transportation and storage. Finally, according to customer needs and transportation requirements, select appropriate packaging materials and methods for packaging.
