Let the auxiliary positioning plate carry the corresponding raw materials, and push the raw materials towards the transfer die through controlling the transfer bracket.

[0057] The movement of the telescopic push groove 62 inside the telescopic push frame 61 drives the transfer die 6, and during the movement, it pushes the front-end raw material towards the position of the replacement support 7 to achieve die pressing production processing.

[0058] As Figure 8 shown, the rear end of the replacement support 7 is fixedly connected to a replacement control support 71.

[0059] The rotation drive motor 74 drives the bottom transmission wheel 73 to rotate, causing the transmission belt 72 to drive the replacement support 7 by rotating the replacement control support 71, enabling the replacement support 7 to correctly rotate to the corresponding position and cooperate with the die pressing support 8 to achieve die pressing production processing.

[0060] As Figure 9As shown, there are four die carriers 81 distributed in an array on the outside of the die pressing bracket 8.

By controlling the transfer bracket 9 to push the raw materials towards the transfer die 6, during the pushing process, the flipping and pushing bracket 94 is used to push the rotating bottom pushing frame 65, so that the limiting ring 64 can carry the corresponding raw materials.

[0063] An aluminum profile forming method includes the following steps:

[0064] Step 1: When die pressing production treatment is required, the cutting knife at the front end of the feeding port 14 is driven by the top driving cylinder 13 at the top of the base mechanism 1, so that the cutting knife can cut the aluminum alloy raw materials for producing aluminum profiles passing through the feeding port 14.

[0065] Step 2: The high-quality aluminum profile raw materials after cutting will stay at the top of the bearing bracket 92 at the front end of the transfer support plate 91. Let the auxiliary positioning plate 93 carry the corresponding raw materials, and by controlling the transfer bracket 9, push the raw materials towards the transfer die 6. During the pushing process, the flipping and pushing bracket 94 is used to push the rotating bottom pushing frame 65, so that the limiting ring 64 can carry the corresponding raw materials.

[0066] Step 3: Then, let the transfer bracket 9 drive the transfer support plate 91 to return to its position, so that the raw materials are placed at the rear end of the corresponding die pressing bracket 8.

Let the drawing bracket 4 drive the transmission bracket 5 and the transfer die 6 to achieve corresponding die pressing treatments of different types.

[0067] Step 4: When wire drawing production processing is required, drive it in the opposite direction to the previous step by using an external motor, so that the wire drawing support 4 is driven in the reverse direction, causing the wire drawing support 4 to drive the wire drawing rod 41 to flip forward, enabling the movable push plate 45 to be correspondingly pushed towards the bottom end. At the same time, the push spring 46 is compressed, the push plate 47 moves towards the bottom end, and the movable push frame 49 slides inside the moving receiving groove 411, causing the rod at the bottom end of the push plate 47 to drive the transmission support 5 to move;

[0068] Step 5: After the movement in the previous step, utilize the downward movement of the expansion support frame 51 at the bottom end of the transmission support 5, in cooperation with the fixed bottom support 54 and the auxiliary push rod 53, to drive the expansion push shaft 52 to move outward until the outer expansion push shaft 52 can fully hold the outer (23), and drive the outer (23) to move outward by pulling the wire drawing support 4;

[0069] Step 6: During the process of the previous step, the high-quality aluminum alloy tube is driven to the thinnest position inside the wire drawing die 3. In cooperation with the expansion push shaft 52, fix the positioning wire drawing inner die 32, enabling the positioning wire drawing inner die 32 to cooperate with the wire drawing die 3 to draw the thick tube into the corresponding thin tube, thus realizing the wire drawing production processing.
