Die
(18) Die means the tooling used in a press for cutting or forming material. An upper and a lower die make a complete set. (19) Die builder means any person who builds dies for power presses. (20) Die set means a tool holder held in alignment by guide posts and bushings and consisting of a lower shoe, an upper shoe or punch holder, and guide posts and bushings. (21) Die setter means an individual who places or removes dies in or from mechanical power presses, and who, as a part of his duties, makes the necessary adjustments to cause the tooling to function properly and safely. (22) Die setting means the process of placing or removing dies in or from a mechanical power press, and the process of adjusting the dies, other tooling and safeguarding means to cause them to function properly and safely. (23) Die shoe means a plate or block upon which a die holder is mounted. A die shoe functions primarily as a base for the complete die assembly, and, when used, is bolted or clamped to the bolster plate or the face of slide. (24) Ejector means a mechanism for removing work or material from between the dies. (25) Face of slide means the bottom surface of the slide to which the punch or upper die is generally attached. (26) Feeding means the process of placing or removing material within or from the point of operation. (27) Automatic feeding means feeding wherein the material or part being processed is placed within or removed from the point of operation by a method or means not requiring action by an operator on each stroke of the press. (28) Semiautomatic feeding means feeding wherein the material or part being processed is placed within or removed from the point of operation by an auxiliary means controlled by operator on each stroke of the press. (29) Manual feeding means feeding wherein the material or part being processed is handled by the operator on each stroke of the press. (30) Foot control means the foot operated control mechanism designed to be used with a clutch or clutch/brake control system. (31) Foot pedal means the foot operated lever designed to operate the mechanical linkage that trips a full revolution clutch. (32) Guard means a barrier that prevents entry of the operator's hands or fingers into the point of operation. (33) Die enclosure guard means an enclosure attached to the die shoe or stripper, or both, in a fixed position. (34) Fixed barrier guard means a die space barrier attached to the press frame. (35) Interlocked press barrier guard means a barrier attached to the press frame and interlocked so that the press stroke cannot be started normally unless the guard itself, or its hinged or movable sections, enclose the point of operation. (36) Adjustable barrier guard means a barrier requiring adjustment for each job or die setup. (37) Guide post means the pin attached to the upper or lower die shoe operating within the bushing on the opposing die shoe, to maintain the alignment of the upper and lower dies. (38) Hand feeding tool means any hand held tool designed for placing or removing material or parts to be processed within or from the point of operation. (39) Inch means an intermittent motion imparted to the slide (on machines using part revolution clutches) by momentary operation of the Inch operating means. Operation of the Inch operating means engages the driving clutch so that a small portion of one stroke or indefinite stroking can occur, depending upon the length of time the Inch operating means is held operated. Inch is a function used by the die setter for setup of dies and tooling, but is not intended for use during production operations by the operator. (40) Jog means an intermittent motion imparted to the slide by momentary operation of the drive motor, after the clutch is engaged with the flywheel at rest. (41) Knockout means a mechanism for releasing material from either die. (42) Liftout means the mechanism also known as knockout. (43) Operator's station means the complete complement of controls used by or available to an operator on a given operation for stroking the press. (44) Pinch point means any point other than the point of operation at which it is possible for a part of the body to be caught between the moving parts of a press or auxiliary equipment, or between moving and stationary parts of a press or auxiliary equipment or between the material and moving part or parts of the press or auxiliary equipment. (45) Point of operation means the area of the press where material is actually positioned and work is being performed during any process such as shearing, punching, forming, or assembling. (46) Press means a mechanically powered machine that shears, punches, forms or assembles metal or other material by means of cutting, shaping, or combination dies attached to slides. A press consists of a stationary bed or anvil, and a slide (or slides) having a controlled reciprocating motion toward and away from the bed surface, the slide being guided in a definite path by the frame of the press. (47) Repeat means an unintended or unexpected successive stroke of the press resulting from a malfunction. (48) Safety block means a prop that, when inserted between the upper and lower dies or between the bolster plate and the face of the slide, prevents the slide from falling of its own deadweight. (49) Single stroke means one complete stroke of the slide, usually initiated from a full open (or up) position, followed by closing (or down), and then a return to the full open position. (50) Single stroke mechanism means an arrangement used on a full revolution clutch to limit the travel of the slide to one complete stroke at each engagement of the clutch. (51) Slide means the main reciprocating press member. A slide is also called a ram, plunger, or platen. (52) Stop control means an operator control designed to immediately deactivate the clutch control and activate the brake to stop slide motion. (53) Stripper means a mechanism or die part for removing the parts or material from the punch. (54) Stroking selector means the part of the clutch/brake control that determines the type of stroking when the operating means is actuated. The stroking selector generally includes positions for Off (Clutch Control), Inch, Single Stroke, and Continuous (when Continuous is furnished). (55) Trip or (tripping) means activation of the clutch to run the press. (56) Turnover bar means a bar used in die setting to manually turn the crankshaft of the press. (57) Two-hand trip means a clutch actuating means requiring the concurrent use of both hands of the operator to trip the press. (58) Unitized tooling means a type of die in which the upper and lower members are incorporated into a selfcontained unit so arranged as to hold the die members in alignment. (59) Control system means sensors, manual input and mode selection elements, interlocking and decision-making circuitry, and output elements to the press operating mechanism. (60) Brake monitor means a sensor designed, constructed, and arranged to monitor the effectiveness of the press braking system. (61) Presence sensing device initiation means an operating mode of indirect manual initiation of a single stroke by a presence sensing device when it senses that work motions of the operator, related to feeding and/or removing parts, are completed and all parts of the operator's body or hand tools are safely clear of the point of operation. (62) Safety system means the integrated total system, including the pertinent elements of the press, the controls, the safeguarding and any required supplemental safeguarding, and their interfaces with the operator, and the environment, designed, constructed and arranged to operate together as a unit, such that a single failure or single operating error will not cause injury to personnel due to point of operation hazards. (63) Authorized person means one to whom the authority and responsibility to perform a specific assignment has been given by the employer. (64) Certification or certify means, in the case of design certification/validation, that the manufacturer has reviewed and tested the design and manufacture, and in the case of installation certification/validation and annual recertification/revalidation, that the employer has reviewed and tested the installation, and concludes in both cases that the requirements of 1910.217 (a) through (h) and appendix A have been met. The certifications are made to the validation organization. (65) Validation or validate means for PSDI safety systems that an OSHA recognized third-party validation organization: (i) For design certification/validation has reviewed the manufacturer's certification that the PSDI safety system meets the requirements of 1910.217 (a) through (h) and appendix A and the underlying tests and analyses performed by the manufacturer, has performed additional tests and analyses which may be required by 1910.217 (a) through (h) and appendix A, and concludes that the requirements of 1910.217 (a) through (h) and appendix A have been met; and (ii) For installation certification/validation and annual recertification/revalidation has reviewed the employer's certification that the PSDI safety system meets the requirements of 1910.217 (a) through (h) and appendix A and the underlying tests performed by the employer, has performed additional tests and analyses which may be required by 1910.217 (a) through (h) and appendix A, and concludes that the requirements of 1910.217 (a) through (h) and appendix A have been met. (66) Certification/validation and certify/validate means the combined process of certification and validation.
