Overview: This document provides technical specifications for guided ejector pins, focusing on shoulder style and straight style pins. It includes detailed measurements, material specifications, and hardness ratings.
Specifications:- Shoulder Style Pins: The document lists dimensions for shoulder style pins with nominal diameters of 1/2", 3/4", and 1". Tolerances for diameter, length, and other parameters are specified. The material used is AISI 8620 with a core hardness of approximately 25 HRC and a surface hardness of 58-60 HRC.
- Straight Style Pins: Dimensions for straight style pins with nominal diameters of 3/4", 7/8", and 1" are provided. The material is AISI 1117 with a core hardness of approximately 25 HRC and a surface hardness of 58-62 HRC.
Procedures: For custom pins, users are directed to refer to templates in section X, which is not included in the provided text.
Key Measurements:- Shoulder Style: Tolerances for diameter (d), base (b), and other dimensions are provided with specific values for each nominal diameter.
- Straight Style: Similar tolerances and dimensions are provided, with a 15° tapered lead-in feature.
Material and Hardness: Both pin styles use different steel grades with specified core and surface hardness levels, ensuring durability and performance in applications.
