技术定义与适配语境
典型 对中环 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A precision-machined annular component designed to ensure accurate concentric alignment between the die holder and press ram in stamping, molding, or forming machinery. It eliminates radial play and maintains consistent tooling position during high-cycle operations.

组件规格

定义
A precision-machined annular component designed to ensure accurate concentric alignment between the die holder and press ram in stamping, molding, or forming machinery. It eliminates radial play and maintains consistent tooling position during high-cycle operations.
工作原理
Utilizes interference fit or precise clearance with mating surfaces to create a rigid mechanical interface that restricts lateral movement while allowing axial force transmission. The ring's geometric accuracy ensures the die holder remains perfectly centered relative to the press axis.
材料
High-carbon tool steel (AISI D2/D3)hardened to 58-62 HRC with surface finish Ra ≤ 0.8 μm. Alternative: Tungsten carbide for extreme wear applications.
Parallelism
≤ 0.01 mm
ID tolerance
H7
OD tolerance
h6
Concentricity
≤ 0.005 mm
Surface hardness
≥ 58 HRC
Thermal stability
≤ 0.002 mm/100°C
标准
ISO 286-2DIN 7154

常见问题

What causes alignment ring wear in high-cycle applications?

Micro-fretting from cyclic radial loads, abrasive contamination, or thermal expansion mismatches between ring and holder materials.

How often should alignment rings be inspected?

Every 50,000 cycles for preventive measurement of concentricity and surface wear, with replacement recommended at 0.02 mm dimensional deviation.
