Especially when there are certain requirements for lateral force on pillar-type aluminum profiles, only steel plate pillars can be used, which limits the use of such aluminum profiles to a certain extent. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an aluminum profile extruder, which has a simple structure, is convenient and practical. By driving the rotating die to rotate through a rotating die device, a spiral shape is formed on the inner wall of the aluminum profile, so as to improve the strength of the side force of the aluminum profile.

The hydraulic extrusion mechanism and the extrusion module are installed on the base. The extrusion head and the aluminum column positioning mechanism are connected to the hydraulic extrusion mechanism. The cutting device is connected to the extrusion module. The extrusion module includes an adjustment sliding seat, a fixed seat, an adjustment oil cylinder, a rotating die, and a fixed die. Each adjustment oil cylinder is installed on the fixed seat, and the piston rod penetrates the fixed seat and is connected to the adjustment sliding seat. The adjustment sliding seat and the fixed seat are respectively penetrated with an extrusion hole and a discharge hole. A fixed die groove is formed on the fixed seat and is used for installing the fixed die. A positioning column for fixing the fixed die is arranged in the fixed die groove. A rotating groove is formed on the adjustment sliding seat, and a rotating die device is installed in the rotating groove. The rotating die is installed on the rotating die device.

[0006] Preferably, the rotating die device includes an adjustment motor, a worm, a rotating ring, a bearing, and a rotating ring positioning column. The rotating ring is installed in the rotating groove through the bearing. The adjustment motor is installed on the adjustment sliding seat, and the power rod is connected to the worm. One end of the worm penetrates one side of the adjustment sliding seat and extends into the rotating groove. A worm tooth matching with the worm is formed on the circumferential surface of the rotating ring. A plurality of rotating ring positioning columns are connected to the rotating ring and are used for positioning the rotating die.

[0007] Preferably, a positioning oil cylinder is installed on the adjusting sliding seat, a fixed needle is installed on the piston rod of the positioning oil cylinder, and one end of the fixed needle penetrates through the adjusting sliding seat and cooperates with the rotating circle.

[0008] Beneficial effects:

[0009] (1) For an aluminum profile extruder of the present utility model, its structure is simple, convenient and practical. The rotating die device drives the rotating die to rotate, so that a spiral shape is formed on the inner wall of the aluminum profile to improve the strength of the side force of the aluminum profile.

[0010] (2) For an aluminum profile extruder of the present utility model, the adjusting oil cylinder separates the adjusting sliding seat and the fixed seat, so that the rotating die and the fixed die can be quickly replaced. At the same time, the relative position accuracy during die installation of the rotating die and the fixed die is ensured by the positioning column and the rotating circle positioning column.
