19、stablished in December 1973, Technical Committee 30 to develop an American National Standard addressing the interchangeability of bolsters, press tooling, and mounting provisions between general purpose presses of comparable bed size, capacity, and type. The B5-TC30 membership consists of a balance

20、between manufacturers, users, accessory suppli- ers and others associated with power presses. The technical committees work was based on the Joint Industry Conference (JIC) Press Room Standards, once the most widely used document, to develop a standard for mechanical power presses, and basic data su

21、bmitted by U.S. manufacturers of power presses. In April 1983, the committee completed the final draft of “Standard for Straight Side Type Presses (Metric).” This draft was not submitted for approval before the committee became inactive. In 1995, Technical Committee 30 was reestablished to continue

22、the pursuit of the original objectives set forth in 1973. The scope of the Standard was expanded to include hydraulic power presses. ASME B5.61-2003 was approved by the American National Standards Institute on July 7, 2003. vASME B5 STANDARDS COMMITTEE Machine Tools Components, Elements, Performance

31、LE ACTION, STRAIGHT SIDE TYPE 1 SCOPE, PURPOSE, AND APPLICATION 1.1 Scope This Standard applies to hydraulic and mechanical power presses commonly referred to by the metal- working industry as General Purpose, Single Action, Straight Side Type Power Presses that, by means of dies or tooling attached

32、 to the slide and bolster, are used to shear, punch, form, or assemble metal or other materials. The following types of presses are excluded from this Standard: (a) air (pneumatic) (b) bench (c) eyelet machines (d) forging (e) four slide machines (f) gap frame (g) knuckle joint (h) multiple action (

33、i) multiple slide (j) spotting (k) transfer feed (l) turret punching 1.2 Purpose The purpose of this Standard is to define and describe power presses and their interface, and to permit inter- changeability of bolsters, dies, and tooling components between presses of comparable type, size, and capaci

34、ty. 1.3 Application Any power press described herein and referred to as an American National Standard Power Press shall comply with the applicable requirements delineated in this Standard. 2 DEFINITIONS AND TERMINOLOGY Terms used in this Standard are defined in ASME B5.49, Glossary of Power Press Te

42、ower Press) 4.3.1 Function of the Flywheel. The energy required for performing press operations is stored in the flywheel. During the working portion of the press cycle, the fly- wheel slows down as it supplies the required energy to the drive train. 4.3.2 Function of the Drive Motor. The drive moto

43、r restores flywheel energy during the nonworking portion of the press cycle, which may include the interval between press cycles for presses operating in single stroke modes. 4.3.3 Drive Motor Selection. The selection of the drive motor is dependent upon the energy requirements. Fac- tors determinin

44、g the energy requirements are: (a) rated capacity (b) press speed (strokes per minute) (c) press stroke Based on the optimum slide velocity for the material being worked, a longer stroke press will be required to operate at a slower speed than a shorter stroke press. The longer the stroke, the deepe

45、r the draw that can be made, and the greater the energy required to sustain the press through the depth of the draw. Table 3 specifies typical press speed/drive motor relationships. 4.3.4 Drive Motor/Flywheel Relationship. The usable energy that a flywheel can supply is a function of the ability of

46、the drive motor to tolerate slowdown without overheating. The usable flywheel energy, expressed as 2 Table 3 Press Speed/Drive Motor Relationship Press Speed, spm Type of Motor Required 10 spm or less Design D, 8% 13% slip Between 10 spm and 30 spm Design D, 5% 8% slip 30 spm or more Design B, 3% 5%

47、 slip a percentage of total flywheel energy, is a function of the motor slowdown. Table 4 specifies the properties of the three types of single speed drive motors that are most commonly used on mechanical power presses. Mandatory Appendix IV provides a method for calculat- ing the usable flywheel en

48、ergy. 4.3.5 Variable Speed Presses. Unless otherwise spec- ified by the purchaser, usable flywheel energy for vari- able speed presses shall be rated at one-half the maximum speed. IMPORTANT: The energy range for a variable speed press varies as the square of the speed range. For example, a speed ra

49、nge of 3:1 would provide an energy range of 9:1. For a press with a speed range of 20 spm to 60 spm, the following would be the energies available: SPM Energy Available, % 20 45 30 100 60 400 4.4 Structural Capacity (a) Bed and slide design shall be based on symmetri- cally distributed loading of the bed and slide over two- thirds of the left-to-right and front-to-back area dimen- sions of the bed and the slide, respectively. The bed size is normally the bolster area. NOTE: Tool design should be based on distributing full capacity loading of the press
