At the third process flow, an inwardly facing projection part 35 is formed at a portion adjacent to the step part for closing one end of the concave groove by inserting a tip end part of the second punch 25, a diameter of which is the same as that of the large diameter hole into the larger diameter hole, for an upset plasticity deformation of the material by abutting to the step part.例文帳に追加

第３の工程では、素材の大径穴と同径の第２パンチ２５の先端部を大径穴に挿入し段部に当接して素材を据え込み塑性変形させることにより、素材の段部に隣接する部分に内向き突出部３５を形成して凹溝の一端を閉鎖する。 - 特許庁

A primary molded body having a shaft part, is formed by applying a forward extrusion molding to a workpiece (S1) and further, a secondary molded body having a large diameter part is formed by applying an upset forming thereto (S2).例文帳に追加

ワークに対して前方押し出し成形を施すことにより軸部を有する第１次成形体を形成し（Ｓ１）、さらに据え込み成形が施されることにより大径部を有する第２次成形体を形成する（Ｓ２）。 - 特許庁

Flow in the radial direction, i.e., radius expansion (upset) is caused in a material with a punch 52 in the vicinity of the upper end of a small diameter part d1, and the expanded material is allowed to bite an inwardly projecting bar 542 of a stock hole 541.例文帳に追加

小径部ｄ１の上端近傍では、パンチ５２によって材料には半径方向の流動、つまり拡径（据え込み）を起こさせ、拡径した材料を、素材穴５４１の内向き凸条５４２に食い込ませる。 - 特許庁

When welding the tip member 3 of a rod which is the solid round bar made of the carbon steel whose outer diameter is almost the same as that of a rod main body 2 to the end face of the rod main body 2 which is a tubular member made of carbon steel, the friction pressure welding is performed by a friction pressure and an upset pressure lower than standard conditions.例文帳に追加

炭素鋼製の管状部材であるロッド本体２の端面に、外径がロッド本体２と略同一の炭素鋼製の中実丸棒であるロッド先端部材３を接合する際、標準条件より低い摩擦圧力及びアプセット圧力で摩擦圧接する。 - 特許庁
