PURPOSE:To make conveyance higher in speed and efficiency by moving downward a feed bar from an intermediate position to attract works, rising and moving the bar for the full stroke, dropping the works from the intermediate position and resetting again the bar to the initial position. CONSTITUTION:A feed bar 25 is reset and moved downward to the side 2 and a work 52 is attracted to a holder 35. A power transmission shaft 6 is moved to the side 3 by a driving device for lifting and the bar 25 is risen 60 for the full stroke by a lift 4. The bar 25 is moved 61 by one pitch to the side 3 integrally with a carriage 26 by a driving device for forward and backward movement. The bat 25 is then moved downward 62 by a half stroke to drop the work 52 onto a die 54. The holder 35 is further escaped to the outside of the press forming section and the bar 25 is moved 63 by one pitch to the side 2. The holder 35 is reset into the forming section after the pressing operation and the bar 25 is moved downward 64 to attract the work 52. The conveyance is thus made possible by one reciprocating motion, by which the operation is made higher in speed and efficiency. |
