• Description:
  Safety aspects of positive clutch power presses used in the metal forming and fabrication industry were discussed with particular reference to a study of work injuries in New York state from 1966 to 1970. Guard emplacement on such machines may interfere with the press's capacity to perform multiple functions. Such guards may therefore serve to increase risks associated with operating the machinery, since they can make work performance on multiple tasking equipment cumbersome. In the New York study of injury experience, 28 percent (6,368) of 22,538 injuries on metal working machines involved power presses. About 20 to 25 percent of all injuries associated with all metal working machines involved point of operation exposures on power presses. During power press primary operation, proper positioning of the stock must be achieved without requiring the operator to insert his hands into the point of operation. Die set must therefore be designed for positioning of the stock. Design considerations include ease of stripping the part from a punch or from the die and ejection of the part without the necessity of the operator inserting his hands into the point of contact. In secondary operations, design considerations should take advantage of gravity, pneumatic, or mechanical knockout concepts. Proper feeding, part ejection, and scrap ejection must be considered when the die set is designed. The author recommends research into basic machine and tool design and human factors engineering to develop effective protection at points of operation of multiple purpose machines.
