The invention relates to the technical field of bridge construction, and discloses a preheating type reinforcing
steel bar cutting device. The preheating type reinforcing
steel bar cutting device comprises a working table, wherein a slide block is movably connected with the right side of the upper end of the working table, a support block is movably connected with a part, close the left side of anA-shaped support, of the upper end of the working table, a heating box body is movably connected with the upper end of the support block, a connection rod is movably connected with the reverse side of a bottom housing, a
cutting tool is movably connected with the lower end of the connection rod, a hydraulic rod is movably connected with the upper end of the connection rod, a bolt is movably connected with the left end of a rotary
handle, and a heat conduction block is movably connected with the left end of the bolt. The preheating type reinforcing
steel bar cutting device can achieve the purpose of easily controlling the length of a reinforcing steel bar by using structures of the slide block, a long column, a groove, a vernier and the like cooperatively, thereby achieving the effect of strictly controlling the length of the reinforcing steel bar, and by using the structures of the heating box body, the rotary
handle, the bolt, the heat conduction block and the like, the effect of reducing cutting pressure of the reinforcing steel bar is achieved, and use life of the cutting device is prolonged.
