3、tional Standard, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by B11 Standards, Inc. The Association For Manufacturing Technology (the ANSI-accredited standards developing organization). American National Standards a

4、re developed through a consensus process. Consensus is established when substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections

5、be considered, and that a concerted effort be made toward resolution. This process brings together volunteers and/or seeks out the views of persons who have an interest in the topic covered by this publication. While B11 Standards, Inc. administers the process and establishes procedures to promote f

6、airness in the development of consensus, it does not write the document and it does not independently test, evaluate or verify the accuracy or completeness of any information or the soundness of any judgments contained in its standards or guidelines. American National Standards are promulgated throu

25、ican National Standard B11.17-2004.) The primary objective of this standard is to eliminate, control or reduce hazards to individuals associated with horizontal hydraulic extrusion presses by establishing requirements for the design, construction, operation and maintenance of these machines. To acco

26、mplish this objective, responsibilities have been assigned to the supplier (e.g., manufacturer, modifier, rebuilder and integrator), the user, and individuals in the working environment. The words “safe“ and “safety“ are not absolutes. An element of safety is attitude. While the objective of this st

27、andard is to eliminate, control, or reduce hazards, this standard recognizes that hazards cannot be practically reduced to zero in any human activity. This standard is not intended to replace good judgment, proper training, and personal responsibility. Operator skill, job monotony, fatigue, and expe

28、rience are safety factors that should be considered by the user. The original B11.17 Standard was approved in 1982 and reaffirmed in 1989 as originally written. B11.17 was then revised and approved in 1996. This current standard was then revised (its third) by the B11.17 Subcommittee, processed and

29、administered by the Secretariat, and approved by the B11 Accredited Standards Committee for submittal to the ANSI Executive Standards Council as an American National Standard. Horizontal hydraulic extrusion press technology is continuously evolving. This standard reflects the most commonly used and

30、time-tested state of the art at the time of its approval. The inclusion or omission of language relative to any evolving technology, either in the requirements or explanatory area of this standard, in no way infers acceptance or rejection of such technologies. Inquiries with respect to the applicati

31、on of the substantive requirements of this standard and suggestions for its improvement are welcomed and are to be sent to the B11 Standards, Inc. POB 690905, Houston TX 77269, USA. Attention: B11 Secretariat. EFFECTIVE DATE The following is informative guidance only, and not a normative part of thi

32、s standard. This Subcommittee recognizes that some period of time after the approval date on the title page of this document is necessary for suppliers and users to develop new designs, or modify existing designs or manufacturing processes in order to incorporate the new or revised requirements of t

33、his standard into their product development or production system. This Subcommittee recommends that suppliers complete and implement design changes within 30 months of the approval of this standard. For existing or modified machines, users should confirm that the equipment / process has tolerable ri

34、sk using generally recognized risk assessment methods. If the risk assessment shows that modification(s) is necessary, refer to the requirements of this standard to implement protective measures for appropriate risk reduction. This standard was processed and submitted for ANSI approval by the B11 Ac

35、credited Standards Committee on Safety Standards for Machine Tools. Committee approval of this standard does not necessarily imply that all committee members voted for its approval. At the time this document was approved as an American National Standard, the ANSI B11 Accredited Standards Committee w

38、linger Can Manufacturers Institute Geoffrey Cullen General Motors Corporation Michael Taubitz Deere no deviation is permitted. The term “SHOULD” denotes a recommendation, a practice or condition among several alternatives, or a preferred method or course of action. Similarly, the term “CAN” denotes

39、a possibility, ability or capability, whether physical or causal, and the term “MAY” denotes a permissible course of action within the limits of the standard. B11 conventions: Operating rules (safe practices) are not included in either column of this standard unless they are of such nature as to be

40、vital safety requirements, equal in weight to other requirements, or guides to assist in compliance with the standard. The B11 standards do not use the term “and/or” but instead, the term “OR” is used as an inclusive disjunction, meaning one or the other or both. A distinction between the terms “ind

41、ividual” and “personnel” is drawn. Individual includes personnel (employees, subcontractors, consultants, or other contract workers under the indirect control of the supplier or user) but also encompasses persons who are not under the direct or indirect control of the supplier or user (e.g., visitor

42、s, vendors, etc.). Gauge refers to a measuring or testing instrument; gage refers to a limiting device (e.g., backgage). Suggestions for improvement of this standard will be welcome. They should be sent to B11 Standards, Inc. POB 690905, Houston TX 77269, USA - Attention: B11 Secretariat. viii Intro

43、duction The primary purpose of every machine tool is to process parts. Hazards exist that may result in injury during production, maintenance, commissioning and de-commissioning. The primary purpose of the ANSI B11 series of machine tool safety standards is to devise and propose ways to minimize ris

44、ks of the potential hazards. This can be accomplished either by an appropriate machine design, by restricting personnel or other individuals access to hazard areas, and by devising work procedures to minimize personnel exposure to hazardous situations. This is the essence of the ANSI B11 series of s

45、afety standards. The responsibility to reduce these risks to a tolerable level, or eliminate them is divided between the equipment supplier, its user and its operating personnel, as follows (numbers in parentheses refer to the clause numbers in these standards which address that responsibility): As

46、an aid to both supplier and the user, an audit checklist of important requirements has been provided in Annex C.

47、ORMATION (Not part of the requirements of American National Standard for Machine ToolsSafety Requirements for Horizontal Hydraulic Extrusion Presses- ANSI B11.17-2004) 1 Scope 1.1 General E1.1 The requirements of this standard apply only to those horizontal hydraulically powered presses that extrude

48、 metals by means of applying sufficient pressure to an individual metal billet, confined within a container, to force the metal to be extruded through the configured openings of a die. The horizontal hydraulic extrusion press, hereafter referred to as a press, is a hydraulically powered machine that

49、 functions to extrude metals horizontally either by the direct or indirect process. It includes components necessary to handle and process metals from the loading mechanism through the platen exit or external butt shear. Components include control systems, hydraulic power systems, main force application cylinder and ram, auxiliary hydraulic and pneumatic cylinders that move components that are an integral part of the extruding machine, material loading mechanism, material pressure containment device, tooling used to
