Safety of machine tools - Hydraulic press brakes

This European Standard specifies technical safety requirements and protective measures to be adopted by persons undertaking the design, manufacture and supply of hydraulic press brakes which are designed to work cold metal or material partly of metal and hereafter referred to as machines.
This European Standard also covers hydraulic press brakes, whose primary intended use is the cold working of metal, which are to be used in the same way to work other sheet materials such as cardboard or plastic.
The requirements in this European Standard take account of intended use, including foreseeable misuse as defined in 3.22 of EN ISO 12100-1:2003. This European Standard presumes access to the press brake from all directions, deals with the hazards described in Clause 4, and specifies the safety measures for both the operator and other exposed persons.
This European Standard also applies to:
- ancillary devices which are an integral part of the press brake, e.g. back gauges and adjustable front sheet supports;
- machines which are integrated into an automatic production line where the hazards and risk arising are comparable to those of machine working separately.
The requirements of this European Standard apply to all hydraulic press brakes whatever the technology used in their control system, e.g. electromechanical and/ or electronic.
This European Standard does not apply to machines whose principal designed purpose is:
a)   sheet folding by rotary action;
b)   tube and pipe bending by rotary action;
c)   roll bending.
This European Standard applies to machines built after the date of issue of this European Standard.
This European Standard does not cover the safety aspect of automatic loading and unloading equipment.
Some guidance how to take into account additional automatic loading and unloading equipment can be found in ISO 11161.

Sicherheit von Werkzeugmaschinen - Hydraulische Gesenkbiegepressen

Diese Europäische Norm legt technische Sicherheitsanforderungen und Schutzmaßnahmen fest, die von
Konstrukteuren, Herstellern und Lieferanten von hydraulischen Gesenkbiegepressen für die Kaltbearbeitung
von Metall oder teilweise aus Metall bestehendem Werkstoff zu verwenden sind. Die hydraulischen
Gesenkbiegepressen werden im Folgenden Maschinen genannt.
Diese Europäische Norm gilt auch für hydraulische Gesenkbiegepressen, deren ursprünglicher
Verwendungszweck die Kaltbearbeitung von Metall ist und die in gleicher Weise für die Bearbeitung von
anderem Tafelmaterial wie Pappe oder Kunststoff eingesetzt werden sollen.
Die in dieser Europäischen Norm enthaltenen Anforderungen berücksichtigen die bestimmungsgemäße
Verwendung und schließen vorhersehbare missbräuchliche Verwendung ein, wie in 3.22 der
EN ISO 12100-1:2003 definiert. Diese Norm unterstellt Zugang zur Gesenkbiegepresse von allen Seiten,
behandelt die in Abschnitt 4 beschriebenen Gefährdungen und legt die Sicherheitsmaßnahmen für den
Bediener und andere in der Nähe befindlichen Personen fest.
Diese Europäische Norm gilt ebenfalls für:
Zusatzeinrichtungen, die fester Bestandteil der Gesenkbiegepresse sind, z. B. hintere Anschläge und
verstellbare Werkstückauflagen an der Vorderseite.
Wenn Gefährdungen und Risiken vergleichbar mit Einzelmaschinen sind, gilt diese Norm auch für
Maschinen, die in eine Fertigungslinie integriert sind.
Die Anforderungen dieser Europäischen Norm gelten für alle hydraulischen Gesenkbiegepressen, unabhängig
von der Art wie sie gesteuert werden, z. B. elektromechanisch und/oder elektronisch.
Diese Europäische Norm gilt nicht für Maschinen, deren Hauptzweck in folgendem besteht:
a) Schwenkbiegen von Tafelmaterial;
b) Biegen von Rohren durch Schwenkbewegung;
c) Rundbiegen zwischen Walzen.
Diese Europäische Norm gilt für Maschinen, die nach dem Ausgabetag dieser Norm gebaut wurden.
Diese Europäische Norm deckt keine Sicherheitsaspekte in Bezug auf automatische

Sécurité des machines-outils - Presses plieuses hydrauliques

La présente Norme européenne spécifie les prescriptions techniques de sécurité et les mesures de protection
que doivent respecter les personnes chargées de la conception, de la construction et de la fourniture des
presses plieuses hydrauliques prévues pour le travail à froid des métaux ou des matériaux partiellement
constitués de métal, et appelées ci-après machines.
La présente Norme européenne s'applique également aux presses plieuses hydrauliques pour lesquelles
l'utilisation normale première est le travail à froid des métaux et qui sont utilisées de la même manière pour le
travail d'autres matériaux en feuilles tels que le carton ou le plastique.
Les prescriptions de la présente Norme européenne tiennent compte de l'utilisation normale y compris les
mauvais usages prévisibles tels que définis en 3.22 de l’EN ISO 12100-1:2003. La présente Norme
européenne suppose un accès possible à la presse plieuse de tous les côtés, traite des phénomènes
dangereux décrits en 4 et spécifie les mesures de sécurité à la fois pour l'opérateur et les autres personnes
exposées.
La présente norme est applicable également aux :
⎯ dispositifs auxiliaires faisant partie intégrale de la presse plieuse, par exemple: butées arrières et
consoles supports de tôle avant réglables ;
⎯ machines qui sont intégrées dans une chaîne de production automatisée où les phénomènes dangereux
existants et les risques potentiels sont comparables à ceux d’une machine travaillant isolément.
Les prescriptions de la présente Norme européenne s’appliquent à toutes les presses plieuses hydrauliques
quelle que soit la technologie utilisée pour leur système de commande, électromécanique et/ou électronique.
La présente Norme européenne n'est pas applicable aux machines conçues principalement pour :
a) le pliage de feuille par rotation ;
b) le pliage de tube et tuyau par rotation ;
c) le cintrage.

Varnost obdelovalnih strojev - Zavore hidravličnih stiskalnic

Ta evropski standard določa varnostne tehnične zahteve in varnostne ukrepe, katere morajo upoštevati osebe, ki se ukvarjajo z načrtovanjem, proizvodnjo in dobavo zavor hidravličnih stiskalnic, ki so zasnovane za obdelavo hladne kovine ali delno kovinskih materialov, v nadaljevanju imenovane stroji. Ta evropski standard prav tako pokriva zavore hidravličnih stiskalnic, katerih osnovna predvidena uporaba je hladna obdelava kovin, ki se enako uporabljajo pri obdelavi drugih materialov v ploščah, kot je karton ali plastika. Zahteve tega evropskega standarda upoštevajo predvideno uporabo, vključno s predvidljivo napačno uporabo, kot je opredeljena v točki 3.22 EN ISO 12100-1:2003. Ta evropski standard predvideva dostop do zavor stiskalnic iz vseh smeri, obravnava nevarnosti opisane v klavzuli 4 ter opredeljuje varnostne ukrepe tako za operaterja kot za druge izpostavljene osebe. Ta evropski standard velja tudi za: - pomožne naprave, ki so sestavni del zavore stiskalnice, npr. zadnji omejevalniki in nastavljivi prednji podporniki za plošče; - stroje, ki so integrirani v avtomatsko proizvodno linijo, kjer so nevarnosti in tveganje, ki se pojavljajo, primerljivi s tistimi pri strojih, ki delujejo ločeno. Zahteve tega evropskega standarda veljajo za vse zavore hidravličnih stiskalnic, ne glede na tehnologijo, ki se uporablja v njihovih kontrolnih sistemih, npr. elektromehanična in/ali elektronska. Ta evropski standard velja za stroje, ki so zgrajeni po datumu izdaje tega standarda. Nekaj vodil, kako upoštevati dodatno avtomatsko opremo za nakladanje in razkladanje, je mogoče najti v ISO 11161.

EN 12622:2009 (E) 5 Introduction This European Standard is a C type standard as defined in EN ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When provisions of this C type standard are different from those which are stated in A or B standards, the provision of this C type standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this C type standard. In addition, press brakes comply as appropriate with EN ISO 12100-1 and EN ISO 12100-2 for hazards which are not covered by this standard. The requirements of this European Standard concern designers, manufacturers, suppliers and importers of machines described in the scope. This European Standard also includes information to be provided by the manufacturer to the user. SIST EN 12622:2010
