Claims

[Scope of Claim for Utility Model Registration] 1. In a charging material charging device for charging charging material as a material to be melted into a melting crucible of a vacuum induction melting furnace, this charging material charging device alone: Alternatively, a hanging member for connecting the charge charging device that grips the charge material to a hook or the like, a gripping arm that securely grips the charge so that it can be opened, and one side for opening and closing the gripping arm. an opening/closing arm having one end pivoted to approximately the center of the gripping arm and the other end pivotally connected to the lower end of the hanging member; It has a vertical guide with a through hole that guides the crucible in a slidable manner, and when the gripped charge is suspended and its lower end reaches the bottom of the crucible, the gripping arm opens outward by a slider crank mechanism. A charge material charging device for a vacuum induction melting furnace, characterized in that the charge material is released and left in the crucible by the user, and then lifted up while keeping the gripping arm open. 2. In the charging material charging device according to claim 1,
A gripping shoe that directly contacts the charging material of the gripping arm is formed as a separate member from the gripping arm body, and this gripping shoe contacts the charging material according to its taper and surface irregularities, and the gripping shoe A charging material charging device for a vacuum induction melting furnace, characterized in that the gripping arm is connected to the main body by a connecting member so that a certain degree of relative angle change is possible. 3. In the charge feeding device according to claim 1 or 2, when the lower end of the charge reaches a predetermined position above the bottom of the crucible, the gripping arm opens outward to release the charge. A charging material for a vacuum induction melting furnace characterized by having a positioning member for opening a gripping arm that allows additional charging during melting by dropping into the molten metal in the crucible without giving a harmful impact to the crucible. Insertion device.
