摘要： A metal-bonding adhesive composition consisting essentially of 95 - 60% by weight, based on the total composition, of an aliphatic homopolyamide and 5 - 40% by weight, based on the total composition, of an aliphatic copolyamide, said homopolyamide being a crystalline homopolyamide having up to 14 amide groups per 100 carbon atoms, and said copolyamide consisting of 90 - 70% by weight of (1) a polyamide having up to 14 amide groups per 100 carbon atoms and 10 - 30% by weight of (2) at least one polyamide whose recurring units are different from those of said polyamide (1), and a metallic can body composed of a metal blank, both side end portions of which are bonded by the side-lap-seam interposed by a layer of said adhesive composition.

摘要： A hardened surface layer is formed in the region of inner and outer surfaces of a hollow material having a central through hole, then the hollow material is hot-forged into a hollow gear-like forged body by a forging die having a first die element with a piercing punch entering into the central through hole of the hollow material from one side thereof and having a second die element with a piercing punch entering into the central through hole of the hollow material from another side thereof. The forging die forms teeth of the gear on the outer side of the hollow material while producing an annular flash in the central through hole of the hollow material between the piercing punches. A distance between the piercing punches in a closed condition of the forging die defines a thickness of the annular flash which is 0.3 mm or more and no greater than 1.3 times (130%) of a depth of the hardened surface layer. After that, the annular flash is removed from the forged body, and thermal refining is implemented to the forged body by quenching and tempering.

摘要翻译： 在具有中心通孔的中空材料的内表面和外表面的区域中形成硬化表面层，然后通过具有第一模具元件的锻造模具将中空材料热锻成中空的齿轮状锻造体， 穿孔冲头从其一侧进入中空材料的中心通孔，并且具有第二模具元件，其具有穿刺冲头从另一侧进入中空材料的中心通孔。 锻造模具在中空材料的外侧上形成齿轮的齿，同时在穿孔冲头之间的中空材料的中心通孔中产生环形闪光。 在锻造模具的闭合状态下的穿孔冲头之间的距离限定了环形闪光的厚度，其为硬化表面层的深度的0.3mm以上且不大于1.3倍（130％）。 之后，将环形闪光体从锻造体中取出，通过淬火回火对锻造体进行热精炼。
