Many hydraulic presses are utilized to clamp an assembly and subsequently insert other components into that assembly. Neff has supplied presses to do this type of operation before, however without any data feedback. The problem that is often encountered is that even when a component such as a bushing fully inserted (i.e. the bushing shoulder fully bottoms on its assembly), there is no assurance that the press fit is correct. Tolerance stack-up in the bushing size and the mating hole size will sometimes present a too loose or too tight condition resulting in costly part failures in the field.
Neff’s Force-vs-Distance Measurement and Data Acquisition System was integrated into a special 12Ton column press to rectify this problem. The system allows the machine operator to key in minimum and maximum force set point values and the distance window that these figures will be evaluated within. Each inserted component has its own force and distance feedback plus its own individual set points. Allowable values for maximum and minimum force are determined by doing trial runs with the upper and lower limits of interference fits between the inserted component that was faulty and the amount of force achieved during the pressing cycle. Based upon this measurement, the operator can now make the decision not only that a bad part is present, but also can determine why it is bad, (i.e. the bushing was too large or the mating hole was too small or too large).
The system has successfully indentified failed parts that would not have been caught with previous inspection procedures. The bottom-line story is that these faulty parts could have caused serious problems if they failed in the field.
