>> Product Name


Excavator bucket Pin Shaft


>> Product Use

Connection function: 


As the connecting pin of the horse-drawn head bucket, its main function is to reliably connect the bucket of Caterpillar E326/E329 and other excavators with the horse-drawn head and other components, ensuring that the bucket can be firmly installed on the excavator during the excavation operation, and work in conjunction with other working devices to achieve normal excavation, loading and unloading operations.


Transmission function:

 When the excavator is working, it can transmit power from the hydraulic system and mechanical structure of the excavator, so that the bucket can perform various actions according to the operating requirements, such as cutting in during excavation, lifting during lifting, and flipping during unloading, etc., to ensure that the bucket's actions are accurate and efficient.


Ensure stability:

 It can maintain the stability and positioning accuracy of the bucket under different working conditions. During the excavation process, it prevents the bucket from shaking, deflecting, etc., ensures the accuracy and efficiency of the excavation operation, improves the work quality and efficiency, and also helps to reduce the wear and failure risks of the equipment.


>> Product Characteristics


High strength and wear resistance: 

It is usually made of high-quality alloy steel material. After a special heat treatment process, it has high strength and hardness. It can withstand the huge pressure, tension and impact force generated by the bucket during the excavation process, and is not easy to deform and break. At the same time, good wear resistance can ensure that the friction loss between the pin and the connecting parts is small during long-term use, extending the service life.


High-precision processing: 

In order to ensure precise matching with the bucket and the horse head, the pin has undergone high-precision processing technology, and the dimensional accuracy and shape and position tolerances are strictly controlled. This allows the pin to be tightly combined with the connecting parts after installation, with uniform gaps, avoiding problems such as loosening and shaking, and ensuring the stability and reliability of the excavator.


Good corrosion resistance:

 Considering that excavators are usually used in various harsh working environments and may be exposed to rain, soil, sand and gravel, and various corrosive substances, the bucket pin has good corrosion resistance. The surface has undergone special anti-corrosion treatment, such as electroplating, phosphating, etc., which can effectively prevent the pin from rusting and corrosion, and extend its service life in harsh environments.


Interchangeability and versatility: 

As an OEM product, the 234-3931 bucket pin has good interchangeability and versatility. It can perfectly match the original parts of specific excavator models such as Caterpillar E326/E329, and can replace the original parts to facilitate the repair and maintenance of the equipment, reducing repair costs and downtime.

Other special materials or treatments


Surface-hardened steel: 


In addition to selecting the appropriate basic material, in order to further improve the wear resistance and corrosion resistance of the pin, the pin of the Carter excavator sometimes uses surface-hardened steel. For example, through surface treatment processes such as carburizing and nitriding, a hardened layer with high hardness and good wear resistance is formed on the surface of the pin, while the interior still maintains good toughness, so that the surface of the pin is not easy to wear and corrode when it is subjected to high friction and corrosive environments, while it can withstand certain impact loads, thereby improving the overall service life and reliability of the pin.


Special alloy materials:


 In some high-end or special models of Carter excavators, some special alloy pins may be used. These special alloy materials are usually designed to meet specific working environments or performance requirements. For example, excavators working in extreme environments such as high temperature, high cold, and high corrosion may use alloy pins containing special elements (such as nickel, molybdenum, vanadium, etc.) to ensure that the pin can still maintain good performance and stability under extreme conditions.

Raw material preparation

Material selection: 

According to product requirements, select suitable steel, such as the aforementioned 4140, 42CrMo and other alloy structural steels or 45# steel and other high-quality carbon structural steels to ensure that the chemical composition and mechanical properties of the material meet the standards.


Cutting:

According to the size specifications of the pin, use cutting equipment (such as sawing machine, flame cutting machine, plasma cutting machine, etc.) to cut the steel into suitable blanks. The blanking size should take into account the subsequent processing allowance.


Forging processing

Heating the blank: 

Put the cut blank into the heating furnace and heat it to the appropriate forging temperature range. The forging temperature of different steels is different, generally around 1000℃-1200℃, so that the blank reaches a good plastic state.

Rough processing: 

Clamp the forged blank on lathes, milling machines, drilling machines and other machine tools for rough processing, including turning the outer circle, milling the plane, drilling the center hole and other processes, remove most of the allowance, and leave a processing allowance of 0.5mm-1mm for subsequent finishing.

Heat treatment: 

After rough machining, the pin shaft is heat treated, such as quenching and tempering, to improve the mechanical properties of the pin shaft, such as hardness, strength and toughness. Determine the specific heat treatment process parameters, such as quenching temperature, holding time, cooling medium, etc., according to the material and product requirements.

Finishing: 

After heat treatment, the pin shaft is finely processed. High-precision lathes, grinders and other equipment are used to fine-turn and fine-grind the outer circle, end face and other parts of the pin shaft to ensure that the dimensional accuracy and surface roughness of the pin shaft meet the design requirements. The dimensional tolerance can be controlled within ±0.01mm, and the surface roughness reaches Ra0.8-Ra1.6μm.

Keyway and other feature processing: 

According to the design requirements, the keyway, oil hole and other features on the pin shaft are processed using milling machines, slotting machines and other equipment to ensure their size and position accuracy.

Surface treatment

Cleaning and degreasing: 

Clean the pin shaft after machining to remove impurities such as oil stains and iron filings on the surface. Ultrasonic cleaning, chemical cleaning and other methods can be used to ensure surface cleanliness.

Rust-proof treatment: 

In order to improve the corrosion resistance of the pin, the cleaned pin is subjected to rust-proof treatment, such as electroplating, hot-dip galvanizing, blackening treatment, etc. Electroplating can form a uniform metal protective film on the surface of the pin, hot-dip galvanizing can obtain a thicker zinc layer, and blackening treatment can form a black oxide film on the surface, which can effectively prevent the pin from rusting.

Dimensional accuracy detection: 

Use calipers, micrometers, three-coordinate measuring instruments and other measuring tools to conduct a comprehensive inspection of the various dimensions of the pin, including diameter, length, keyway size, etc., to ensure that the dimensional deviation is within the design tolerance range.

Appearance quality inspection:

Check the appearance of the pin by visual inspection or using optical instruments to check whether there are defects such as cracks, sand holes, pores, bumps, etc. The surface should be smooth and free of burrs.

Hardness test: 

Use a hardness tester to test the hardness of different parts of the pin to check whether the hardness meets the requirements after heat treatment to ensure the mechanical properties of the pin.

Flaw detection:

Use flaw detection equipment (such as ultrasonic flaw detector, magnetic particle flaw detector, etc.) to detect the pin shaft to check whether there are defects such as cracks inside to ensure the quality reliability of the pin shaft.


Packaging and storage

Packaging protection:

Pack the pin shafts that have passed the inspection. According to customer requirements and transportation methods, select appropriate packaging materials, such as plastic bags, paper boxes, wooden boxes, etc., and pack the pin shafts individually or in batches to prevent damage and corrosion during transportation and storage.
