摘要： PURPOSE:To reduce manufacturing cost by providing a sub-die that slides on the recess of a die and flushing the tip of a thin projection of a work that comes out to the recess. CONSTITUTION:A die 11 having unevenness of the shape corresponding to a product is supported by a ram 12 and a holder 13 is fitted to it. A projected part 16 that projects in a recess part 15 of the die 11 is formed in a sub-die 14 fitted slidably in the die 11. When the sub-die 14 and punch 18 start operation, the sub- die 14 retreats until the work 4 is brought into contact with the tip face 20 of the die 11 by the pressure face 17 of a punch 18. When the punch 18 advances further, the work 4 projects to the recess 15, and a pedestal part 1 and a scroll part 2 are formed. Fluidity of the work 4 is increased in the aperture between the subdie 14 and formed part 16, and all tip faces come into contact with the formed part 16. Thus, a scroll part 2 of uniform height is formed, and cost can be reduced.

摘要： PURPOSE:To improve the yield of a material by providing induction heating coils to the runner parts connecting a central sprue and a casting mold and heating the runners so as to prevent a molten metal from solidification in the stage of casting thereby eliminating the defective product to be resulted from solidification of the molten metal in the runners and making the runners smaller. CONSTITUTION:A molten metal B is poured through a central sprue 4B and runners X into casting molds 1B. Induction heating coils Z are embedded in the runners X and the runners X are heated to the temp. equal to the temp. of the molten metal to prevent the molten metal from being cooled in the runners X. The manufacture of a defective product by the solidification of the molten metal B in the runners X is eliminated by such mechanism. Since the runners X can be made small, the yield of the material is improved, the need for exerting pressure to the metal B is eliminated and the cost is reduced.

摘要： PURPOSE:To work efficiently defect-free annular parts having no under fill by inserting a fitting member which fills the bore of a prepunched blank material into said bore and subjecting the blank material to extrusion working while acting back pressure from the counter extrusion direction. CONSTITUTION:A blank material 1 consisting of preliminary punching is set into a blank material holder PH. A main punch P1 and an auxiliary punch P2 are lowered and the punch P2 is first inserted into the bore of the material 1. On the other hand a lower punch KO is raisen from below to support the bottom surface of the material 1. Forming is thereafter started and the punch P1 is lowered together with the punch P2 to force the material 1 into the die LD while the back pressure against the punch P1 is exerted thereto from below by the lower punch KO. The defect-free annular part product having no under fill and collapsion of the bore is thus easily obtd. with one stage.

摘要： PURPOSE:To form easily and quickly a gear without dimensional errors and to reduce cost by heating locally the outside circumferential surface of an annular blank material to a prescribed temp., pressing a toothed punch thereto to deform plastically the blank material and performing said operation at an equal interval over the entire circumference of the blank material. CONSTITUTION:An annular blank material 1 is inserted and fixed to a mandrel 2 having a stopper 4. The outside circumferential surface of the ring is locally heated to a prescribed temp. in a high frequency furnace C and a toothed punch X is pressed thereto to deform plastically the material 1 to a tooth profile. Such operation is executed at an equal interval over the entire circumference of the blank material. Since the material is locally heated, the dimensional error over the entire part is decreased and the material is worked in a short time. The gear may be subjected again to hot punching or be finished by final cold punching in order to improve the accuracy of the tooth profile.

摘要： PURPOSE:To reduce or eliminate the side thrust of a work roll for performing high speed rolling and preventing the damage of bearings by crossing a backup roll and a work roll with each other, in performing the cross rolling by upper and lower work rolls. CONSTITUTION:Though a cross rolling by work rolls 1, 2 is performed for improving the accuracy of sheet thickness, side thrusts exert respectively on the rolls 1, 2 to increase the loads of bearing parts. The thrusts are dispersed by crossing respectively the work rolls 1, 2 and backup rolls 3, 4 with each other, and the thrusts exerting on the rolls 1, 2 can be offset with each other to a zero level by adjusting them. That is, when the inclination angle of the rolls 3, 4 is made smaller than the inclination angle thetaW of the work rolls 1, 2 by angle DELTAtheta, the directions of thrusts FW and FB are made reverse to each other to offset them with each other. Thus, the thrust F to a mechanism for receiving the thrust load is reduced.
摘要翻译：目的：为了减少或消除用于执行高速轧制的工作辊的侧向推力，并且通过上下工作辊进行横轧，防止轴承通过支承辊和工作辊彼此交叉而损坏轴承。构成：虽然为了提高板厚的精度而进行用工作轧辊1的横轧，但分别在辊1,2上施加侧向推力，以增加轴承部的负荷。通过将工作辊1,2和支承辊3,4彼此交叉而将推力分散，并且通过调整它们，施加在辊1,2上的推力可以彼此偏移到零水平。也就是说，当使辊3,4的倾斜角小于工件辊1,2的倾斜角度θW的角度DELTAtheta时，推力FW和FB的方向互相反向以便使它们各自偏移其他。因此，减小了用于接收推力载荷的机构的推力F.
