PURPOSE:To change the stroke of a reciprocating motion by the eccentric quantity of an eccentric pin, by bringing a transfer slide to a reciprocating motion by utilizing the eccentric pin of a planetary gear which is engaged to a sun gear provided on the shaft of a main gear. CONSTITUTION:When a shaft 11 rotates by synchronizing with a press, a main gear 15 rotates through gears 12, 13 and 14, and the planetary gear rotates itself and revolves around a sun gear 21. At the same time, an eccentric pin 23 brings a slider 26 to a reciprocating motion along a guide rod 25, and the rack 28 of the slider 26 rotates a pinion 29 in the forward and backward directions. Also, an arm 31 provided on the shaft 30 of a pinion 29 is oscillated and brings a transfer slide 34 to the reciprocating motion along a guide rod 33. Accordingly, the reciprocating motion section of the transfer slide 34 becomes an advance/return motion of a feed bar 37. |
