Description
本発明は、以下のような発明である。
複数の枝部を有する金属鍛造製品の製造方法において、側面に表面層を有する円柱状素材を用いて、表面部位に表面層を有するように閉塞鍛造法にて粗形材を成形する粗仕上鍛造工程と、表面部位に表面層を有している粗形材を用いて表面層をバリとして製品部位外に押出す中間仕上鍛造工程とを含み、中間仕上鍛造工程において、金型成形孔の製品部位の外側に設けられている表面層排出部の上に、粗形材のうち、その厚みが成形品の厚みより小さい部位の表面部位を配置し、前記表面部位を表面層排出部に押出し、前記金型成形孔とは別の、製品部位より外周側の高さが製品部位と同等または低い第２表面層排出部が設けられている第２金型成形孔の製品部位の端より製品部位内側に、粗形材のうち、厚みが成形品の厚みより大きい部位の表面部位を配置し、前記表面部位を第２表面層排出部に押出すことを特徴とする。
The present invention is as follows.
In a method for producing a metal forged product having a plurality of branches, a rough finish forging is performed by using a cylindrical material having a surface layer on a side surface and forming a rough material by a closed forging method so as to have a surface layer on a surface portion. process and comprises the extruding intermediate finish forging step outside products site surface layer with a rough profile which has a surface layer on the surface portion as burrs, the medium between the finish forging step, the molding hole On the surface layer discharge part provided on the outside of the product part, a surface part of the rough shaped material whose thickness is smaller than the thickness of the molded product is arranged, and the surface part is extruded into the surface layer discharge part. The product from the end of the product part of the second mold forming hole provided with a second surface layer discharge portion, which is different from the mold part hole and has a height on the outer peripheral side equal to or lower than that of the product part. Inside the part, the part of the rough shape whose thickness is greater than the thickness of the molded product The surface sites arranged, characterized in that extruding said surface portion on the second surface layer discharge unit.
本発明の金属鍛造製品の製造方法は、側面に表面層を有する円柱状素材を用いて、表面部位に表面層を有するように閉塞鍛造法にて粗形材を成形する粗仕上鍛造工程と、表面部位に表面層を有している粗形材を用いて表面層をバリとして製品部位外に押出す中間仕上鍛造工程と、を含み、中間仕上鍛造工程において、金型成形孔の製品部位の外側に設けられている表面層排出部の上に、粗形材のうち、その厚みが成形品の厚みより小さい部位の表面部位を配置し、表面部位を表面層排出部に押出し記金型成形孔とは別の、製品部位より外周側の高さが製品部位と同等または低い第２表面層排出部が設けられている第２金型成形孔の製品部位の端より製品部位内側に、粗形材のうち、厚みが成形品の厚みより大きい部位の表面部位を配置し、表面部位を第２表面層排出部に押出すので、鍛造用素材が鍛造製品の複数の枝部に層状に塑性流動する為、機械的特性が向上し、また、側面に表面層を有する円柱状素材を用いている為、工程の省力化ができ、鍛造用素材に対する製品の歩留り向上に適し、その結果、車両用サスペンション部品やその粗形材を安価に、かつ効率よく製造できる。 The method for producing a metal forged product of the present invention uses a columnar material having a surface layer on the side surface, a rough finishing forging step of forming a rough shaped material by a closed forging method so as to have a surface layer on the surface portion, seen including a finishing extruding middle unauthorized product site forging process, the surface layer with a rough profile which has a surface layer on the surface portion as burrs, the intermediate finish forging step, the product site of the molding hole On the surface layer discharge part provided on the outer side of the rough shape material, the surface part of the part whose thickness is smaller than the thickness of the molded product is disposed, and the surface part is extruded into the surface layer discharge part. Separately from the molding hole, the height on the outer peripheral side from the product part is equal to or lower than the product part. Of the rough shape material, place the surface part where the thickness is larger than the thickness of the molded product, Since extruding a site on the second surface layer discharge portion, since the forging material is plastic flow in layers into a plurality of branches of the forged product, and improved mechanical properties, also cylindrical material having a surface layer on the side surface Therefore, it is possible to save labor in the process and to improve the yield of the product with respect to the forging material. As a result, it is possible to manufacture the suspension part for a vehicle and its rough shape at low cost and efficiently.
