To obtain a shearing machine for decomposition of a large aircraft which is suitable for decomposition of an aircraft such as a passenger aircraft or the like with use of a strong aluminum alloy or the like.SOLUTION: A shearing machine comprises: a tip blade of which a cutting point enters into a shearing object; a shearing blade of a first jaw part comprising a pair of first parallel shearing blades which are bent at an obtuse angle with respect to an entry direction of the cutting point, and are located on blade width both surfaces, and a pair of second parallel shearing blades which are bent at an obtuse angle with respect to a fitting part of the first parallel shearing blades, and are located on blade width both surfaces; and a shearing blade of a second jaw part which comprises a reception blade for these shearing blades. This shearing machine comprises, as the tip blade: a cutting edge comprising an edge part, and a pair of tip taper blades, of which a blade width is increased toward a rear end thereof, on both sides of the edge; and a pair of taper blades which are bent at an obtuse angle with respect to a fitting part of rear end part of the tip taper blades, and are arranged over the first parallel shearing blades.SELECTED DRAWING: Figure 1

    【課題】 強度のアルミ合金等を使用した旅客機等の飛行機を解体するに好適な大型飛行機解体用剪断機を得る。【解決手段】 剪断対象物に対して切っ先が侵入する先端刃と、この先端刃の侵入方向に対して鈍角状に曲折して刃幅両面に配置された一対の第1平行剪断刃と、この第1平行剪断刃取付部に対して鈍角状に曲折して刃幅両面に配置された一対の第2平行剪断刃とを備えた第1ジョー部の剪断刃と、これら剪断刃の受け刃を備えた第2ジョー部の剪断刃とを備え、先端刃として、小口部とこの小口部の両側に後端に向かって刃幅が増加される一対の先端テーパー刃とを備えた切っ先刃と、先端テーパー刃の後端部の取付部に対して鈍角状に曲折して第1平行剪断刃に亘って配された一対のテーパー刃とを備える。【選択図】 図1
