The invention relates to amolding method for an angledscrew capofan
airplane, which is mainly used for connecting sheet
metal parts of the
airplane. A cold upsetting mold is arranged on a cold upsetting
machine; a blank is conveyed into a
cutting bushing through a
pulley, and is then conveyed to a female mold through a cutter, so that the blank and the female mold are kept on the same horizontal line; when the blank slightly enters the female mold, the cutter gets back to an original position, and the blank is upset into the female mold through a
stamping mold I, so that the blank is pressed against a female mold mandrel; when the
stamping mold I moves forwards continually, the blank is pre-molded by aprimary upsetting master mold on the head part of a workpiece, so that the head part of the workpiece becomes an eccentric
mushroom head shape; after the end of pre-molding, the
stamping mold I and a stamping mold II move vertically through a slide block on a
machine tool, and the stamping mold II is conveyed onto an upsetting line, so that
finial upsetting is performed on the head, and the upset workpiece is pushed out of the female mold mandrel; meanwhile, a charging roller starts to rotate, so that a new working cycle is started.
