PURPOSE:To bring the work up to the specified position at a good timing with a simple construction by providing the member which moves the movable die of a flat die type thread rolling machine upward or downward and is moved upward or downward by this driving power along with this, to at least one of the work transfer-in and out sides. CONSTITUTION:While a movable member 12 is in the up position, the work 100A (hereinafter 100 is omitted) and elevating members 75, 76 are in the illustrated positions. When the work B is held in the B' position and the member 12 is lowered, the work A is sandwiched by stationary and movable dies 1, 11 and is rolled with threads, etc. At the same time, the descending of a rack 51 causes the members 75, 76 to ascend and descend respectively by way of a pinion 53, sprockets 54, 58, chains 66, 67 and the work A having been worked is discharged from a chute 45 onto the member 76 and assumes the A' state. At this time, the member 75 reaches the up position and the work B rolls into the positioning member 80. When the member 12 ascends after this, the shaft 52 revolves inversely to discharge the work A through chute from the A'' state and the work B is set in the work A position from the B'' state. |
