[0015] The invention also discloses a processing method for forming an aluminum profile, which comprises the following steps:

[0016] Step 1: First, place the preheated aluminum columnar blank inside the support seat, then select the required extrusion die, and insert the connecting rod on the extrusion die into the connecting groove on the support block. At this time, the two servo motors on the top of the chassis are rotated through the PLC controller, thereby driving the threaded rod to rotate. At this time, the threaded block and the threaded rod are connected in the threaded relationship, so that the guide block moves on the inner surface of the sliding seat to the side close to the extrusion die, thereby tightening the extrusion die;

[0017] Step 2: At this time, the electric telescopic rod is started to extend, thereby pushing the support seat to move upward on the base frame, and then pushing the aluminum bar upward, and the nut is turned by the external wrench, thereby driving the rotating sleeve to rotate on the inner surface of the through cavity.

When the thrust spring is compressed to a certain extent, the extrusion cylinder continues to extend, thereby pushing the aluminum billet in the support seat into the interior of the guide block. At this time, the electric telescopic rod is shortened to make the support seat move downward. At this time, the push rod is completely inserted into the interior of the sliding groove, and the thrust spring is in a compressed state. At this time, the push block and the push rod extrude the aluminum billet in the guide cavity together, and the aluminum billet passes through the extrusion die to be formed.

Through this structure, not only can the guide block be clamped, but also when the extrusion die is replaced, it only needs to move the guide block to replace it.

[0021] (2) In the present invention, an electric telescopic rod is arranged at the bottom of the base frame, and the extension of the electric telescopic rod is used to drive the support seat to move up and down, so that the aluminum billet can be moved to realize centering of aluminum bars of different diameters, thereby making the aluminum billet aligned with the center of the extrusion die, and a slidable push rod is arranged inside the top block to push the aluminum billet into the inside of the guide cavity, thereby avoiding the support seat from blocking the top block. Through this structure, aluminum billets of different specifications can be aligned with the center position of the extrusion die, ensuring that aluminum billets with smaller diameters can be extruded into aluminum profiles, thereby further improving its practicality.

[0022] (3) In the present invention, a rotatable rotating sleeve is provided through one side of the support seat, which cooperates with the adjusting rod on the push plate, and utilizes a limit strip that can only slide on the inner surface of the limit groove, so that the push plate can be moved upward, thereby achieving fine adjustment of the height of the aluminum billet in the support seat and improving its centering accuracy.
