New Energy Construction Machinery Forgings: Forged and Precision-Machined Base and Hub Wear-Resistant Parts Solutions
With the comprehensive popularization of new energy engineering equipment, new energy wind power equipment and electric construction machinery, new energy equipment has raised qualitative upgrading requirements for the performance of core load-bearing, supporting and walking parts. Traditional ordinary cast and welded parts feature low precision, insufficient strength and easy deformation, which can no longer adapt to the new energy equipment design standards of lightweight, high stability, long service life and zero failure.
In the overall structure of new energy equipment, bases and hubs are the core load-bearing and stress-bearing forging components. The base undertakes the functions of whole-machine fixing, shock absorption and load bearing, while the hub is responsible for walking, transmission, support and buffering. These two core components operate long-term under alternating loads, high-frequency vibration, heavy impact and outdoor corrosion conditions, serving as the most critical wearable and load-bearing parts of new energy construction machinery.
At present, all high-end new energy equipment brands in the industry adopt forging technology to produce base and hub blanks, combined with CNC precision finishing technology to improve dimensional accuracy and assembly fitting degree, fundamentally solving deformation, fracture, wear and looseness problems. This article elaborates on the process advantages, processing procedures and equipment adaptation value of forged bases and forged hubs for new energy construction machinery.
1. Industry Pain Points of Bases and Hubs for New Energy Construction Machinery
Featured by electrification, lightweight design, low noise, long endurance and high stability, new energy construction machinery has far higher requirements for part strength, flatness, wear resistance and fatigue resistance than traditional fuel-powered equipment. Ordinary cast parts have numerous drawbacks:
Cast bases are prone to deformation and fracture: Cast structures are loose with multiple internal pores. Under the high-frequency start-stop and vibration working conditions of new energy equipment, cast bases are easy to warp, deform and crack, resulting in whole-machine inclination and assembly misalignment.
Ordinary hubs suffer from rapid wear and out-of-roundness: Non-forged hubs have uneven material hardness, which easily causes out-of-round deformation, uneven wear and loose bearing positions under long-term rolling pressure, leading to equipment jitter, deviation and excessive noise.
Insufficient precision leads to poor assembly performance: Ordinary machined parts have large deviations in flatness and coaxiality, failing to meet the precision assembly requirements of new energy equipment and easily causing poor sealing, failed shock absorption and uneven stress.
Short service life and high operation and maintenance costs: New energy equipment is designed with a longer service life, while ordinary forgings and castings have poor fatigue resistance. Frequent part replacement seriously affects equipment attendance rate.
Therefore, high-end new energy construction machinery and wind power new energy equipment uniformly adopt the solution offorged bases and forged hubs with precision finishing to realize long-term and stable equipment operation.
2. Core Advantage Comparison: Forged Forgings vs Ordinary Castings
2.1 Forged materials feature dense and uniform structure without internal defects
New energy dedicated forged bases and forged hubs are die-forged at high temperature with high-quality alloy steel. High-pressure forging refines grains and compacts internal defects such as looseness, pores, sand holes and microcracks, forming a uniform and dense metallographic structure without weak stress points. Compared with ordinary castings, forged parts have their strength increased by more than 50% with greatly improved toughness and impact resistance, completely solving fracture and deformation problems of new energy equipment under heavy-load vibration conditions.
2.2 Continuous metal flow lines adapt to long-term fatigue-resistant working conditions of new energy equipment
The forging process forms complete and continuous metal flow lines according to the stress structure of base plates and the annular load-bearing structure of hubs. The flow lines fit the force direction perfectly without the fracture and disorder problems of cast flow lines. Under the long-term high-frequency vibration, continuous load and repeated start-stop conditions of new energy construction machinery, forged forgings possess stronger fatigue resistance, hardly producing hidden cracks and plastic deformation, which greatly extends the overall service life of equipment.
2.3 Stable forged blanks support high-precision finishing
Forged base and hub blanks feature low internal stress, stable material and anti-deformation performance. After stress relief heat treatment, their flatness and structural stability are far superior to castings. Multi-process CNC precision finishing accurately controls flatness, parallelism, hole position accuracy, coaxiality and surface finish, perfectly meeting the precision assembly standards of new energy equipment and achieving tight fitting, stable transmission and reliable shock absorption.
3. Full Process of New Energy Forgings: Forging + Heat Treatment + Precision Finishing
3.1 Precision Forging: Preparation of High-Strength Base and Hub Blanks
Custom forging parameters including temperature, forging ratio and forming rhythm are formulated for the lightweight, high-load and high-stability requirements of new energy construction machinery. Special die forging is adopted for the large-area plate structure of bases and annular load-bearing structure of hubs, ensuring uniform overall hardness, symmetrical structure, consistent bearing capacity and no stress concentration areas, improving the comprehensive mechanical properties of forgings from the source.
3.2 Professional Heat Treatment: Balance Hardness and Toughness for Material Stability
All new energy forgings undergo complete heat treatment processes including normalizing, quenching and tempering, and stress relief annealing to refine metallographic structures and eliminate residual forging stress, balancing hardness and toughness. It ensures high wear resistance and compression resistance of hub surfaces, as well as high toughness, deformation resistance and crack resistance of bases, adapting to all-weather complex working conditions of new energy equipment.
