Abstract

PURPOSE: To form intermittent thread grooves which are uniform and of superior screwing strength on the peripheral surface of a cylindrical stock by pressing respectively a pair of inner die pieces and outer die pieces which are slidable in the horizontal direction by means of a press plate of the specific construction which moves in the direction orthogonal to these.
CONSTITUTION: When a cylindrical stock material D composed of a thin-walled metal plate is put on inner dies 4, 5 and a press plate A is lowered, the pressing surfaces b, c of the press pieces 2,3 engage with the tapered surfacs f, g of outer die pieces 7, 8 respectively and the pressing part a of a rod 1 fits in the recess d between the inner die pieces. This operation causes the outer die pieces to move horizontally so as to narrow the spacing therebetween against respective springs 9 and the inner die pieces to move horizontally so as to widen the spacing therebetween against springs 6. Hence, by the cooperation of the thread grooves e of the inner die pieces and the thread grooves h of the outer die pieces, the thread grooves 11 provided with intermittent surfaces 10 are surely formed on the peripheral surface of the stock and there is not likelihood of causing any distortion and cracking.
