The invention provides an iron chip briquetting device, and belongs to the technical field of metal chip briquetting machines. The iron chip briquetting device comprises a feeding mechanism, a briquetting mechanism and a discharge mechanism; an extrusion block of the briquetting mechanism is arranged in a frame in a up-down sliding manner; a vertical groove and a horizontal groove are staggered in a feeding support base of the feeding mechanism; the lower end of a folding piston rod of a folding module is connected with a folding pressure head; a pushing piston rod of a pushing module is connected with a pushing plate; the pushing plate is slidingly arranged in the horizontal groove; two ends of an opening/closing cylinder of the discharge mechanism are respectively hinged with a first support lug and a second support lug; a discharge support base is hinged to a cross beam; a slide rod is slidingly arranged in the discharge support base; the upper end of the slide rod is connected with a piston rod of an extension cylinder; and one end of a swing cylinder is hinged with a third support lug, and the other end is hinged with the upper end of the discharge support base. The iron chip briquetting device not only can realize quick feeding and briquetting of strip metal wires, but also can realize automatic discharge of molded briquetted blocks, and is high in automation degree.
