Machine tools safety - Presses - Part 2: Safety requirement for mechanical presses (ISO 16092-2:2019)

This document, in addition to ISO 16092-1, specifies technical safety requirements and measures to be adopted by persons undertaking the design, manufacture and supply of the following groups of mechanical presses and mechanical press production systems:
— Group 1: Presses with a part revolution clutch(es);
— Group 2: Presses with a servo drive system (Mechanical servo presses).
NOTE 1 Requirements in this document are essentially applicable to both groups of the mechanical press. If a requirement applies to only one group, then the group is specified.
NOTE 2 Other types of motorized drive systems provide similar functionalities to what is commonly called "servo drives" or "servo motors", and as such their use is considered the same within the terms used in this document (e.g. variable frequency drive systems).
The presses covered by this document range in size from small high-speed machines with a single operator producing small workpieces to large relatively slow-speed machines with several operators and large complex workpieces.
This document deals with all significant hazards relevant to mechanical presses and ancillary devices (e.g. moving die cushions, work-piece ejectors, feeding and transfer systems) which are integral to the machine, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). All phases of the machine life cycle as described in ISO 12100:2010, 5.4 have been taken into consideration.
NOTE 2 All significant hazards means those identified or associated with presses at the time of the publication of this document.
In addition to machines not covered by ISO 16092-1:2017, this document does not cover machines which:
a) transmit energy to impart press slide motion by using hydraulic or pneumatic means;
b) have two or more slides moving in different angular orientations from each other;
NOTE 3 This document applies to presses which have two or more slides moving in the same angular orientations, e.g. a press which has inner and outer slides.
c) transmit energy to impart press slide motion by using a linear motor mechanism(s).

Werkzeugmaschinen-Sicherheit - Pressen - Teil 2: Sicherheitsanforderungen für mechanische Pressen (ISO 16092-2:2019)

Dieses Dokument legt, zusätzlich zu ISO 16092-1, die technischen Sicherheitsanforderungen und  maßnahmen fest, die von Personen zu beachten sind, die mit der Konstruktion, der Herstellung und der Lieferung der folgenden Bauarten von hydraulischen Pressen und den folgenden mechanischen Pressenproduktionssystemen betraut sind.
- Bauart 1: Pressen mit kraftschlüssiger(n) Kupplung(en);
- Bauart 2: Pressen mit einem Servo-Antriebssystem. (Mechanische Servopressen).
ANMERKUNG 1 Die Anforderungen in diesem Dokument gelten im Wesentlichen für beide Bauarten der mechanischen Presse. Gilt eine Anforderung nur für eine Bauart, wird die Bauart spezifiziert.
ANMERKUNG 2 Andere Arten von motorisierten Antriebssystemen bieten ähnliche Funktionalitäten wie das, was allgemein als "Servoantriebe" oder "Servomotoren" bezeichnet wird, und als solche wird ihre Verwendung innerhalb der in diesem Dokument verwendeten Begriffe als gleich betrachtet (z. B. variable Frequenzantriebssysteme).
Die durch dieses Dokument abgedeckten Pressen variieren im Größenbereich von kleinen Hochgeschwindigkeitsmaschinen mit einem einzelnen Bediener, welche kleine Werkstücke produzieren bis hin zu großen Maschinen mit relativ langsamer Geschwindigkeit mit mehreren Bedienern und großen komplexen Werkstücken.
Dieses Dokument befasst sich mit allen für mechanische Pressen relevanten signifikanten Gefährdungen und mit Zusatzeinrichtungen (zum Beispiel das Bewegen von Ziehkissen, Werkstückauswürfe, Zuführungs- und Transfersysteme), die ein fester Bestandteil der Maschine sind, und zwar bei bestimmungsgemäßer Verwendung und unter den Bedingungen von missbräuchlicher Verwendung, welche vom Hersteller vernünftigerweise vorhersehbar sind (siehe Abschnitt 4). Alle Phasen der Lebensdauer der Maschine, wie in ISO 12100:2010, 5.4 beschrieben, haben Berücksichtigung gefunden.
ANMERKUNG 2 Alle wesentlichen Gefährdungen sind solche, die zum Zeitpunkt der Veröffentlichung dieses Dokuments identifiziert wurden oder mit Pressen verbunden sind.
Zusätzlich zu den Maschinen, die nicht von ISO 16092-1:2017 abgedeckt werden, deckt dieses Dokument keine Maschinen ab, die:
a) Energie für die Bewegung des Pressenstößels hydraulisch oder pneumatisch übertragen;
b) über zwei oder mehr Stößel verfügen, die sich in unterschiedlichen Winkelausrichtungen zueinander bewegen;
ANMERKUNG 3 Dieses Dokument gilt für Pressen, die über zwei oder mehr Stößel verfügen, die sich in denselben Winkelausrichtungen bewegen, zum Beispiel eine Presse, die über innere und äußere Stößel verfügt.
c) Energie übertragen, um die Bewegung des Pressenstößels mit Hilfe eines Linearmotor-Mechanismus zu übertragen.

Sécurité des machines-outils - Presses - Partie 2 : Exigences de sécurité pour les presses mécaniques (ISO 16092-2:2019)

Le présent document, appliqué avec l'ISO 16092‑1, spécifie les exigences techniques de sécurité et les dispositions que doivent respecter les personnes chargées de la conception, de la construction et de la fourniture des groupes suivants de presses mécaniques et de systèmes de production des presses mécaniques:
— Groupe 1: Presses à embrayage à friction;
— Groupe 2: Presses avec un système de servo-entraînement (servopresses mécaniques).
NOTE 1 Les exigences du présent document s'appliquent essentiellement à ces deux groupes de presse mécanique. Lorsqu'une exigence ne s'applique qu'à un seul groupe, celui-ci est alors spécifié.
NOTE 2 D'autres types de systèmes d'entraînement motorisés offrent des fonctionnalités similaires à ce que l'on appelle communément les «systèmes de servo-entraînement» ou «servomoteurs», et leur utilisation est donc considérée comme identique dans les termes utilisés dans le présent document (par exemple, les systèmes d'entraînement à fréquence variable).
Les presses couvertes par le présent document vont des petites machines à grande vitesse avec un seul opérateur produisant de petites pièces aux grandes machines à vitesse relativement lente avec plusieurs opérateurs et produisant de grandes pièces complexes.
Le présent document traite de tous les phénomènes dangereux significatifs applicables aux presses mécaniques et dispositifs auxiliaires (par exemple: les coussins mobiles, les éjecteurs de pièces et les systèmes d'alimentation et de transfert) qui font partie intégrante de la machine, lorsqu'elles sont utilisées normalement et dans les conditions de mauvais usage raisonnablement prévisible par le fabricant (voir l'Article 4). Toutes les phases du cycle de vie de la machine, telles que décrites dans l'ISO 12100:2010, 5.4 ont été prises en compte.
NOTE 2 L'expression «tous les phénomènes dangereux significatifs» fait référence à ceux qui sont identifiés ou associés aux presses au moment de la publication du présent document.
Outre les machines non couvertes par l'ISO 16092‑1:2017, le présent document ne couvre pas les machines qui:
a) transmettent de l'énergie pour donner un mouvement du coulisseau de la presse en utilisant des moyens hydrauliques ou pneumatiques;
b) ont deux ou plusieurs coulisseaux mobiles dans différentes positions angulaires les uns par rapport aux autres;
NOTE 3 Le présent document s'applique aux presses qui ont deux ou plusieurs coulisseaux mobiles dans le même positionnement angulaire, par exemple, une presse qui a des coulisseaux intérieurs et extérieurs.
c) transmettent de l'énergie pour donner un mouvement du coulisseau de la presse en utilisant un ou des mécanisme(s) de moteur linéaire(s).

INTERNATIONAL STANDARD ISO 16092-2:2019(E)
Machine tools safety — Presses —
Part 2:
Safety requirement for mechanical presses
1 Scope

This document, in addition to ISO 16092-1, specifies technical safety requirements and measures to

be adopted by persons undertaking the design, manufacture and supply of the following groups of

mechanical presses and mechanical press production systems:
— Group 1: Presses with a part revolution clutch(es);
— Group 2: Presses with a servo drive system (Mechanical servo presses).

NOTE 1 Requirements in this document are essentially applicable to both groups of the mechanical press. If a

requirement applies to only one group, then the group is specified.

NOTE 2 Other types of motorized drive systems provide similar functionalities to what is commonly called

“servo drives” or "servo motors”, and as such their use is considered the same within the terms used in this

document (e.g. variable frequency drive systems).

The presses covered by this document range in size from small high-speed machines with a single

operator producing small workpieces to large relatively slow-speed machines with several operators

and large complex workpieces.

This document deals with all significant hazards relevant to mechanical presses and ancillary devices

(e.g. moving die cushions, work-piece ejectors, feeding and transfer systems) which are integral to the

machine, when they are used as intended and under the conditions of misuse which are reasonably

foreseeable by the manufacturer (see Clause 4). All phases of the machine life cycle as described in

ISO 12100:2010, 5.4 have been taken into consideration.

NOTE 2 All significant hazards means those identified or associated with presses at the time of the publication

of this document.

In addition to machines not covered by ISO 16092-1:2017, this document does not cover machines which:

a) transmit energy to impart press slide motion by using hydraulic or pneumatic means;

b) have two or more slides moving in different angular orientations from each other;

NOTE 3 This document applies to presses which have two or more slides moving in the same angular

orientations, e.g. a press which has inner and outer slides.

c) transmit energy to impart press slide motion by using a linear motor mechanism(s).

3.3
clutch
part revolution clutch
friction clutch

mechanism which engages or disengages the power transmission from the flywheel to the slide by

means of friction at any point in the cycle
3.4
moving direction monitoring

monitoring function which monitors the slide moving direction, directly or indirectly

3.5
standstill monitoring
monitoring function which monitors the slide position, directly or indirectly
3.6
stopping-performance (overrun) monitoring

monitoring function which monitors the slide stopping time, angle or braking distance

3.7
servo drive system

system which replaces the need for a clutch by directly connecting a servo motor to the transmission

system such as gear (motor reducer), timing belt drive mechanism, crank mechanism, mechanical link,

ball screw, harmonic drive reducer, etc.

3.8
protective stop
stop initiated by a protective measure
3.9
safe energized standstill

safety function preventing an unexpected movement of the slide of more than a defined amount from

the stopped position, with energy supplied to the servomotor(s) to resist to external forces, and without

actuation of the mechanical brake(s)
3.10
safe de-energized standstill

safety function preventing an unexpected movement of the slide by removing the energy supply to the

clutch, servomotor(s) and the mechanical brake(s)
3.11
safe stop
stop initiated by a monitoring function
3.12
safe torque off
STO
function which prevents force-producing power from being provided to the motor
3.13
worst case

condition of the press when it would be under foreseeably unfavourable situations e.g., the press slide is

in its most disadvantageous position, with a tool of maximum weight being used, etc.
