The present application belongs to the technical field of low-temperature non-
ferrous metal extrusion forming, and particularly relates to a low-temperature non-
ferrous metal extrusion direct forming
machine, a forming method and a
production line, which are convenient for extruding raw materials such as
cutting materials, broken materials, corner materials, waste materials and broken materials into low-temperature non-
ferrous metal finished products. First, the
raw material variety is diversified. Second, most of the impurities on the surface of the
raw material can be removed. Third,
inert gas is introduced into the inner cavity of the
extrusion cylinder, and the air in the inner cavity of the extrusion cylinder and the inner cavity of the forming die is discharged to prevent the metal from being oxidized. Fourth, the
raw material is softened first and then extruded, and the pressure of each extrusion is reduced through multiple extrusions, thereby improving the
processing reliability. Fifth, multi-stage feeding is realized, the technical problems of uneven feeding and insufficient feeding are solved, and the yield is increased. Sixth, the
piston body extrudes the material to be formed in the extrusion direction L2, and the
cutting edge of the scraper cuts off the softened raw material entering the material bin section from the
discharge port of the feeding structure, thereby reducing the resistance received by the extrusion device. Seventh, the forming die is replaceable.
