The D46 Series cross wedge rolling mill represents a high-end solution in cross wedge rolling technology. Its unique three-roller structure offers unparalleled advantages in addressing the critical challenge of ensuring the core quality of shaft parts. It is a powerful tool for achieving near-net-shape, high-performance, and highly reliable shaft parts.
D46 Series Cross Wedge Rolling Mill Application Case Analysis
Part Background and Challenges
Part: New energy vehicle drive motor shaft. This part typically requires multiple steps, small transition radiuses, and high dimensional accuracy (especially in areas where it press-fits with bearings and gears).
Special Requirements:
Higher Strength and Fatigue Life: The motor rotates at high speeds, and the shaft is subject to frequent torque fluctuations, placing stringent demands on fatigue strength.
Excellent Internal Quality: Any core defects can lead to shaft fracture under extreme loads, resulting in serious failure.
Precise Dimensional Control: Ensures accurate assembly with other components and reduces vibration and noise.
Summary of the Advantages and Applications of Cross Wedge Rolling Mills
Quality-Driven Applications: Particularly suitable for shaft parts requiring extremely high internal quality, fatigue strength, and dimensional accuracy, such as:
Automotive safety components: Transmission shafts, engine camshafts, and new energy vehicle drive shafts.
Core Components for High-End Equipment: Aircraft engine parts, high-speed locomotive axles, and precision machine tool spindles.
High-Volume Production: Like all cross wedge rolling technologies, it is suitable for annual production volumes exceeding hundreds of thousands of pieces, minimizing the high investment in tooling and equipment.
Significant Material Savings: The economic benefits of material savings are particularly pronounced for expensive alloy steel parts.
