Die Setting Components Overview

This document provides detailed specifications and technical data for various types of spring plungers and spring plugs used in die setting applications. It includes load capacities, dimensions, materials, hardness, surface treatments, and ordering information.

1. Spring Plungers (SPSL and SPSH Types)

Two main types of spring plungers are described: SPSL (Light Load Type) and SPSH (Heavy Load Type). Both types are available in different sizes and thread specifications (M3 to M16) with corresponding pitch values.

• Load Capacities: Load values are given in Newtons (N) and kilogram-force (kgf) for initial and final conditions. For example, SPSL plungers have initial loads ranging from 1.9 N (0.2 kgf) to 29.4 N (3.0 kgf), while SPSH plungers range higher, up to 58.8 N (6.0 kgf).
• Dimensions: Parameters such as travel (S), diameter (D), length (L), and thread size (M × P) are specified. Sizes vary from small (M3 × 0.5 pitch) to larger sizes (M16 × 2.0 pitch).
• Materials and Hardness: Nose material is SK4, thread material is SCM435, with hardness between 36 to 40 HRC.
• Surface Treatment: Options include black chromating and galvanizing for corrosion resistance.
• Additional Features: Loosening lock mechanisms are mentioned for secure installation.

2. Spring Plugs (NH Type)

Spring plugs are made from SAE1065 material and are used in conjunction with spring plungers. They feature a 15° chamfer and precise diameter tolerances (+0.6 mm, +0.3 mm).

• Removal Tool: A dowel pin removing tool is available for easy removal of plungers without the need for drilling plugs to access taps.

3. Ordering and Accessories

• Catalog numbers are provided for each size and type, facilitating ordering.
• Plunger wrenches are referenced on page 46 for installation and removal assistance.

4. Summary of Key Parameters

5. Best Practices and Recommendations

• Use the appropriate plunger type (light or heavy load) based on application load requirements.
• Ensure correct thread size and pitch matching for installation.
• Apply recommended surface treatments to enhance durability and corrosion resistance.
• Utilize the dowel pin removing tool for efficient maintenance without damaging components.

This structured data supports selection, ordering, and maintenance of die setting components, ensuring reliable performance in tooling applications.
