摘要： Disclosed herein in dies for forging a gear-shaped part made of a sheet metal, comprising a cylindrical die for forming, in cooperation with a cylindrical punch, tooth portions and bottom land portions at a peripheral wall portion of a cup-shaped work integrally formed from the sheet metal, wherein ridges and grooves provided at the inner peripheral surface of the cylindrical die in the axial direction of the die in order to form the tooth portions and the bottom land portions are such that, in the direction from an insertion-side opening of the cylindrical die toward the depth of the die, the height of the ridges is gradually increased to a final height, then the width of the ridges is gradually increased to a final width, and thereafter the depth of the grooves is gradually decreased to a final depth. The part is forged sequentially stepwise in the order of the bottom land portions, side surfaces of the teeth and the crests of the teeth, namely, from inner to outer side, so that no irrational forces are applied to the work. Therefore, die wear at the terminal ends of the tooth portions of the part can be restrained, and it is possible to secure an effective tooth length and to contrive a compact form of the part. At the same time, an enhanced yield can be contrived through prevention of cracking, and the useful lives of the punch, the die and the like can be prolonged because no irrational forces are applied to the tools.

摘要： Material characteristics that a foamed filler material (s) to be filled in a frame cross section (fr) should have are discussed. By using a material complying with the characteristics, the energy absorbability of the frame (fr) is effectively enhanced. In a frame structure (fr) for vehicle bodies in which a filler material is filled in at least part of the cross section of a frame, the filler material is set to a mean compressive strength of not less than 4 MPa and/or a maximum bending strength of not less than 10 MPa. More particularly, the filler material is set to a mean compressive strength of not less than 5 MPa and/or a maximum bending strength of 60 MPa.

摘要： A pair of left and right front frames are formed with brittle sections on proximal portions of the frames, by the provision of the smaller cross-sectional area than other sections of the frame. The brittle sections and their peripheral sections are processed so as to become approximately equal to the other sections of the front frames in axial compressive strength by way of a hardening treatment like quenching. In an early-phase of a collision, the hardened brittle sections will not buckle so as to induce larger initial load. Thereafter, the brittle sections will buckle because of their lower ductility, so that the front frames begin bending deformation to effectively absorb the collision energy.
摘要翻译：通过提供比框架的其它部分更小的横截面积，一对左右前框架在框架的近侧部分上形成有脆性部分。通过诸如淬火的硬化处理，将脆性部分及其周边部分加工成以相对于前框架的其它部分的轴向压缩强度大致相等。在碰撞的早期阶段，硬化的脆性部分不会弯曲，从而引起较大的初始载荷。此后，由于其较低的延展性，脆性部分将会弯曲，使得前框架开始弯曲变形以有效地吸收碰撞能量。

摘要： The invention provides a method for injection molding a semi-molten melt of metal to a product, wherein a semi-molten melt of metal is injected into a cavity of the mold through a nozzle of injector to mold the product which is divided in a lower solid fraction portion to require strength and a higher solid fraction portion to require molding accuracy along flow of the melt inside the cavity. In the method of the invention, a part of the melt to be earlier injected is determined to be at a lower temperature in the injector than a part to be later injected among the melt parts composing said lower and higher solid portions in the cavity by injecting a batch of the melt, and that the melt is injected into the cavity on the side on which said lower solid fraction portion for the strength of the product is formed.
