Die Guide Components Overview

This document provides detailed specifications and component information for die guide systems, including SGO, SGON, and related types. It covers catalog numbers, dimensions, materials, tolerances, and available options.

1. Component Types and Catalog Numbers

• Components include Guide Bushings (SGO, SGOL), Guide Posts (SGON, SGONL), Guide Holders, Hexagon Socket Head Bolts, and Dowel Pins.
• Catalog numbers are organized by diameter (D) sizes ranging from 25 to 80 mm and lengths (L) from 70 mm up to 450 mm, with increments of 1 mm.
• Different series (SGO, SGON) correspond to specific dimensional ranges and types, such as plain type, with dowel pin holes, or for specific length dimensions.

2. Dimensions and Tolerances

• Key dimensions include diameter (D), length (L), height (H), thickness (T), and various hole sizes (φd, φeH7).
• Tolerances are specified precisely, for example, L1 ±0.01 mm, height tolerances ±0.2 mm, and hole tolerances H7 with specific positive allowances.
• Tables provide detailed measurements for each size, including bolt sizes (M8 to M20), dowel pin diameters, and other critical parameters.

3. Materials and Treatments

• Guide Bushings are typically made from FC250 cast iron or S45C steel with induction hardening to HRC55 or higher.
• Guide Posts use SCM435 or SUJ2 steel, with tolerances up to m6.
• Hexagon Socket Head Bolts and dowel pins are specified with dimensions and materials suitable for assembly and durability.

4. Accessories and Fasteners

• Hexagon Socket Head Bolts are available in various sizes (M8×35 to M20×75) corresponding to guide sizes.
• Dowel pins come in different diameters and lengths to ensure precise location and assembly.
• Guide Post Sets and other accessories are listed with their respective dimensions and tolerances.

5. Options and Customizations

• Several options are available to customize the guide components, including:
• C: Dowel pin hole drilled at the center of the guide post for location accuracy.
• M, W: Tapped holes for height blocks on guide holders or bushings (specific to smaller diameters).
• RH, RB, RHB: Inverted mounting types for guide holders and bushings.
• HK, BK, HBK: Height machining to ±0.1 mm tolerance for guide holders and bushings.
• BM, HM: Tapped holes for lifting bolts or jack screws on guide bushings (for diameters 25 to 50 mm).
• Options are coded and can be specified when ordering to meet precise application requirements.

6. Notes on Ordering and Usage

• Length (L) can be ordered in 1 mm increments to fit specific die requirements.
• Detailed dimensional tables and tolerance specifications ensure compatibility and interchangeability.
• Additional option details are referenced on other pages (e.g., page 116 onwards).

Summary

This technical document serves as a comprehensive guide for selecting and specifying die guide components, emphasizing precise dimensions, material specifications, and customizable options to ensure optimal performance in die assembly applications.
