Abstract
The invention discloses an extruder. The extruder comprises a machine body and an extrusion rod arranged on the machine body; an extrusion head is additionally arranged at one end of the extrusion rod, and includes a fixed pad and an expansion ring; the fixed pad and the expansion ring are connected through a spline; and an annular groove is formed in the outer wall of the expansion ring. Firstly, after the extruder is started, the extrusion rod drives the extrusion head to extrude an aluminum rod to enter a mold; in the extrusion working process, the diameter of the back end of the aluminum rod is increased due to external extrusion force, and the expansion ring is also increased; and as the annular groove is formed in the outer wall of the expansion ring, the ring wall of the expansion ring is thinner, the expansion ring is higher in expansion coefficient, and can totally bear the diameter increasing range of the aluminum rod, the easy separation of the aluminum rod from the expansion ring can be realized without needing higher external force, and the service life of the expansion ring is prolonged. As higher external force is not needed, the rupture condition of a connecting head of the spline in the drawing process is prevented.
