| Popis: |
This paper presents the use of a geared five-bar with connecting rod and sliding output for mechanical presses. Mechanical presses are used to form sheet metal parts and have economical benefits to other presswork production methods. A conventional mechanical press is driven with a slider-crank mechanism. Extended drive presses are used to alter the stamping motion required for certain operations. For instance, certain coining and squeezing operations prefer a long dwell. A knuckle joint mechanism is commercially available and permits some control over the output motion. A synthesis process is developed in this paper to produce a prolonged dwell and is applied to the kuckle joint mechanism. The geared five-bar with sliding output is shown to produce a longer dwell than a knuckle joint mechanism. |
