Overview

This document provides detailed technical specifications, material properties, dimensional data, and ordering information for die guide related parts, specifically focusing on RGPS and RGPSB guide pins, bushings, and assist pins used in large die applications.

1. RGPS Bushing and Guide Pin Specifications

• Material: S45C (equivalent to IC45 or A1045 steel)
• Hardness: HRC 55 to 60, with induction hardening applied at specific areas (marked as B)
• Dimensions: Diameter (D) options starting at 60 mm with length (L) increments of 5 mm, and other parameters such as bore diameter (D1), tolerance classes (f6, h6), and chamfers (R4).
• Tolerances: Diameter tolerances are specified (e.g., D f6, D1 h6), with length tolerances ±0.2 mm.
• Features: 2-M16 tapped holes for assist pin mounting (option code GM), with details referenced on page 20.
• Design Notes: The guide pin length can be extended; machining for assist pin installation is optional (GM machining).

2. Assist Pin (SPGP) Specifications

• Material: S45C (IC45, A1045)
• Dimensions: Diameter options of 60 and 80 mm, length increments of 5 mm ranging from 150 to 600 mm.
• Features: Drill diameter φ15 with tight tolerances (−0.1 to −0.2 mm), chamfer angles of 10°, and dimensional tolerances ±0.2 mm.
• Machining Options: GM machining for assist pin installation on guide pins.

3. RGPSB Guide Pin for Large Die (Bolt Type)

• Material: S45C (IC45, A1045), induction hardened to HRC 55+
• Dimensions and Tolerances: Diameter options of 40, 50, 60, and 80 mm with corresponding lengths from 160 to 290 mm.
• Thread and Bolt Details: Each size has specified thread diameters and depths (e.g., M20×24 for D=40), with accompanying bolts and spring washers included.
• Dimensional Parameters: Detailed measurements for d, e, f, g, J, a, b, and tolerances are provided, including chamfer radii and angles.
• Accessories: Hexagon bolts and spring washers are included with orders.

4. Ordering Information and Options

• Catalog numbers follow the format: RGPS D – L – A or RGPSB D – L with increments in length specified.
• Option codes such as GM indicate additional machining for assist pin mounting.
• Assist pins (SPGP and SPGPB) are ordered separately with their own catalog numbers and size ranges.

5. Critical Parameters and Best Practices

• Ensure correct tolerance classes (f6, h6) are maintained for proper fit and function.
• Induction hardening is critical for wear resistance, especially in areas subject to high stress.
• Chamfer angles (5° and 10°) and radii (R4, R0.4) are important for assembly and stress distribution.
• Use specified bolts and washers to maintain locking and prevent loosening during operation.
• Optional machining (GM) should be specified if assist pin installation is required.

6. Illustrations and Diagrams

The document includes diagrams showing dimensional relationships, chamfer angles, bolt locking mechanisms (looseness lock with bolt and lock plate), and installation examples. Key dimensions such as diameters, lengths, thread sizes, and tolerances are visually represented to aid in correct part selection and assembly.

Summary

This technical document comprehensively details the specifications, materials, dimensions, tolerances, and ordering options for RGPS and RGPSB guide pins, bushings, and assist pins used in large die applications. It emphasizes material hardness, precision tolerances, and optional machining features to ensure proper fit, durability, and functionality in die guide systems.
