[CN 201620184411.5] Angle steel shearing machine stop frame


[CN 201620184411.5] Title of Angle Steel Shearer Blocking Frame: Application Number of Angle Steel Shearer Blocking Frame: CN 201620184411.5 Applicant: Nanjing Xinhua Civil Air Defense Equipment Co., Ltd. Application Date: 2016-3-10 Patent Type: Utility Model An Angle Steel Shearer Blocking Frame, Including Blocking Frame Body, Including Blocking Frame Set along Angle Steel Moving Direction, the baffle is provided with a protrusion on a side facing the angle steel shearing machine, the upper surface of the protrusion abuts against the lower surface of the angle steel, and the width of the protrusion is greater than the width of the lower surface of the angle steel. In this way, according to the length of the required angle steel, the distance from the angle steel shearing machine to the angle steel shearing machine is equal to the length of the required angle steel by sliding the position of the baffle on the cross bar, thus positioning the angle steel. At the same time, the width of the bump is greater than the width of the lower surface of the angle steel, so that the bump can play a maximum supporting role on the lower surface of the angle steel, thereby ensuring that when the angle steel is cut, the angle steel can always maintain a horizontal state, so that the cut after cutting is kept flat, and the angle steel will not be partially recessed due to excessive pressure with the bump.
