High-strength bar extruder

A high-strength bar extruder comprises a rack (1), a driving device (2), a transmission device (3) and an extrusion forming mechanism (4), wherein the driving device (2), the transmission device (3) and the extrusion forming mechanism (4) are respectively installed on the rack (1). The transmission device (3) comprises a machine case (31), a driving shaft (32), a pair of driven shafts (33) and an intermediate shaft (34), the driving shaft (32) is meshed with the driven shafts (33) and the intermediate shaft (34), and the intermediate shaft (34) is meshed with one of the pair of driven shafts (33). The high-strength bar extruder has the advantages that compared with a simple-structure single-screw extruder, the bar extruder has high extrusion action on materials, the materials bear counterforce towards a material outlet on a plurality of structures, adhesion and friction counterforce of the structures to the materials is appropriately reduced, the materials can be extruded to be compact more easily, and forming strength is high.
