摘要： PROBLEM TO BE SOLVED: To provide a multistage form-rolling equipment for a gear which is preferable for obtaining the gear having high precision by providing a rough roller die and a finish roller die coaxially in series in the axial direction thereby securing the true circularity of the form-rolled gear. SOLUTION: A blank 7 is held by a first blank holding part 11. The blank 7 is arranged in a high frequency heating coil 28 by driving a second motor 22, and rotated in its circumferential direction, and an outer circumferential part is induction-heated by the high frequency heating coil 28. The blank 7 is further carried in the direction of the arrow Y1 by the second motor 22, and arranged at the working position R1. First and second rough roller dies 32, 42 are equally and synchronously rotated at the prescribed speed, and pressed to the outer circumferential part of the blank 7 by the press synchronizing command signal from a control system 9 for the prescribed period, and then released. The blank 7 is arranged at the finishing position R2. First and second finish roller dies 33, 43 to be rotated by the press synchronizing command signal from the control system 9 are pressed in a synchronous manner with the blank 7. A tooth part of the blank 7 is subjected to a finish form-rolling in the hot region.

摘要： PURPOSE:To improve seizure resistance and safety by heating a billet after coating a pretreating agent with a boric acid as a main components on a billet and executing warm forging by coating the lubricant with a boron oxide as the main components on the billet. CONSTITUTION:The pretreating agent adding the binder with a boric acid as the main components is coated in a slurry shape on the surface of a billet 3 in a low temp. state. After heating the billet 3 up to about 600-700 deg.C, a lubricant with a boron oxide as the main components is coated by a spray, etc., on its surface. The billet 3 is then heated to 700-850 deg.C to execute warm forging via a container 1 and punch 2. Since the pretreating agent is coated on the billet 3 at low temp. and thereafter warm forging is executed by coating a lubricant at high temp. the oxidation of the billet is effectively checked. Consequently the seizure resistance at forging time is improved and the safety in working is improved as well because no combustible matter is used.

摘要： PURPOSE:To execute forming with a high efficiency without generating a chip, by inserting and holding a discoid base material so as to be rollable by a pair of rack tools having a rolling tooth part, and using a part of the rolling tooth part as a shaping part of particulars which are engaged with a worm wheel which is formed. CONSTITUTION:A pair of rack type tools 16, 18 are provided in a state that a disk- shaped base material 14 is inserted and held so as to be rollable, and as for the tools 16, 18, a tooth part 20 and a tooth part 22 are formed in one side and the other side, respectively. The tooth part 20 becomes a bitten part, and a large irregularity is formed in the discoid base material 14 by applying a large driving fore to the outside periphery of the discoid base material 14. The tooth part 22 is a shaping part for forming exactly this formed irregularity to a worm wheel of a desired size, and becomes particulars to be engaged with the formed worm wheel. In the first half part of forming, the tooth part 20 executes a swell of the tooth and a generating deformation to the outside periphery of the base material 14, and in the latter half, a finish sizing is executed by the tooth part 22. In this way, since the worm wheel is manufactured by a plastic deformation, no chip is generated, and the working efficiency is raised.
