“…The feasibility of engineering treatments for stamping presses has been shown in Ref. 19. Noise is shown to be generated by the so-called "idling" sources (gear noise, air noise, impacts in clearances of the crank mechanism, impacts of the stripper plate against the upper die and keepers) and by the breakthrough event.…”

“…19 was very old, and noisy gears had not been treated, Fig. 18 shows the very substantial effect, 8 dB(A), of cushioning both the clearances in the ball joint between the slide and connecting rod and the stripper plate keepers with thin layered rubber-metal laminates capable of withstanding high impact loading, together with using a high-strength plastic as a structural material for the stripper plate.…”

“…19 In this case, the cushioning materials have to be placed between the joint bushing and the ball box cap, to experience the full extent of the tension force in the connecting rod. Although the tension force magnitude is only a small fraction of the rated press load, it amounts to the specific load of 6 MPa on the bushing/cap contact area.…”

“…For stamping presses, this problem can be resolved by using the pressload simulator developed in Ref. 19 and shown in by the calibrated bolts to the specified load. If the simulator is installed on the press bolster, the press ram hits the head, which can be equipped with strain-gauges, and on its further travel down, unloads the bolts from the spring induced load.…”

A systematic approach to noise abatement in manufacturing plants is described. Eugene I. Rivin~ shows how the correct strategy, together with a thorough understanding of the structural dynamics of noise-generating devices and careful analysis of operational constraints, can achieve very substantial noise reductions with simultaneous improvement in performance and/or durability. Suitable techniques and recommendations were developed and largely implemented for a compressed air system, a material handling system (gravity action sliding and rolling chutes, vibrationstimulated chutes, containers, towed trailers, vibratory feeders), and production machinery. A-weighted sound level reductions up to 30 dB have been demonstrated. III
