Full title and description

STB VDI 3352 E 1992-06 — Change over of large presses and lines for sheet metal working (German title: "Umrüsten von Großpressen für die Blechbearbeitung"). This document records recommended procedures, equipment provisions and checks to be followed when converting large mechanical press installations and press lines for sheet-metal production runs.

Abstract

This guideline/standard (VDI 3352, edition E, published June 1, 1992) defines practical measures and process steps for efficient and safe changeover of large presses and associated feed/transfer lines used in sheet-metal working. It covers material supply, part transport, tool and die change, peripheral services and the checks required to ensure production readiness and process monitoring after conversion. The version bearing the STB prefix represents a national adoption/republishing of the VDI document (STB indicates a national standard designation in some countries).

• Edition / version: E (1992-06).
• Number of pages: Approx. 10 pages.

Scope

The standard provides recommended procedures to plan and execute changeovers of large stamping/press installations and complete press lines for sheet-metal work. It addresses provision and handling of blank stock, infeed and alignment devices, part transport and removal, handling of scrap, safe and efficient tool/die change (for presses with and without transfer tables), preparation of peripheral services (lubrication, compressed air, electrical connections, tooling fixtures), and measures to verify production capability (numerical control setup, process monitoring and trial runs). It is intended as a practical checklist-style guideline rather than detailed machine design rules.

Key topics and requirements

• Requirements for blank-stock supply and infeed equipment (coils, sheets, feeders).
• Guidance on part transport, transfer and removal within press lines (including handling of finished parts and scrap).
• Procedures for tool and die change: sequence, safe handling, and special cases for presses with or without sliding/transfer tables.
• Provisioning of peripheral services and operating supplies (lubrication systems, compressed air, electrical and hydraulic connections, tooling fixtures).
• Checks required to confirm production readiness: NC parameter transfer, process monitoring setup, functional tests and trial runs.
• Recommendations to minimize downtime, improve safety during changeover, and reduce risk of damage to tools or parts.

Typical use and users

Intended users are press-shop engineers, production and line managers, tooling designers, maintenance personnel and safety officers involved in press changeover planning and execution. The guideline is used when planning line conversions, writing work instructions for die changes, training operators on changeover steps, and auditing press-line readiness for new production runs.

Related standards

Documents commonly referenced alongside VDI 3352 include other VDI guidelines on stamping and die components (for example VDI 3370 and VDI 2910), European and ISO standards on press safety and mechanical presses (for example EN/ISO press safety standards), and machine-tool standards addressing transfer and tooling elements used in stamping and forming. Users should consult current EN/ISO press safety standards and later VDI documents for up-to-date safety requirements and design guidance.

FAQ

Q: What is this standard?

A: It is VDI 3352 (edition E, June 1992) — a practical guideline for carrying out changeovers of large stamping presses and press lines used in sheet-metal working; the title shown with an STB prefix indicates a national-republication/adoption of the VDI document.

Q: What does it cover?

A: It covers planning and operational steps for changeover: blank provision, feed and transfer devices, part transport and scrap removal, tool/die change procedures, peripheral service provisioning, and production-readiness checks including NC setup and trial runs.

Q: Who typically uses it?

A: Press-shop and production engineers, tooling and maintenance staff, line managers and safety officers who plan and execute press/die changeovers in sheet-metal manufacturing facilities.

Q: Is it current or superseded?

A: The VDI 3352 E (1992-06) edition is listed as withdrawn (withdrawal recorded on 1 August 2013). Users should consult more recent VDI publications and applicable EN/ISO standards for current safety and design requirements.

Q: Is it part of a series?

A: It is related to other VDI guidance on stamping and die mechanisation (for example VDI 3370 and VDI 2910) and is frequently cited alongside press safety and tooling standards; treat it as one practical guideline within the broader set of VDI documents for stamping and presswork.

Q: What are the key keywords?

A: Press changeover, large presses, press lines, sheet-metal working, tool/die change, blank feed, transfer systems, production readiness, VDI 3352, STB.
