[0001] The present application relates to the technical field of aluminum alloy extrusion processing equipment, and in particular to an aluminum alloy extrusion processing equipment and a processing technology thereof. Background Art

[0002] Aluminum alloy extrusions are products manufactured through the aluminum alloy extrusion molding process. After the aluminum billet is heated to a certain temperature, it is pressed into a mold through an extruder to form the desired shape. Aluminum alloy extrusions have the advantages of light weight, high strength, and corrosion resistance. They are widely used in the automotive, aerospace, construction and other fields. Due to the wide application of aluminum alloy extrusions, there are many structures of aluminum alloy extrusions, especially hollow aluminum alloy extrusions, which have the advantages of light structure and high strength. The processing of hollow aluminum alloy extrusions generally requires two combined molds.

[0003] In the processing of existing aluminum alloy extrusions, each time a new aluminum billet is extruded, the previous aluminum billet will remain in the mold for a period of time. Due to the high temperature, the aluminum alloy raw material is easily thermally bonded to the mold, resulting in an irregular mold surface, which affects the quality of subsequent aluminum alloy extrusion processing. In addition, in the processing of existing aluminum alloy extrusions, due to the length of the extrusion cylinder outside the extrusion rod, it is inconvenient to lubricate the mold, which easily leads to insufficient lubrication of the surface of the mold contacting the aluminum alloy. Summary of the invention

[0015] Furthermore, a positioning sleeve is fixedly installed on one side of the positioning seat away from the fixed seat, and a fixed mold sleeve is mounted on the internal movable sleeve of the positioning seat.

[0017] Furthermore, the processing steps of the processing equipment for processing the aluminum alloy extrusions are as follows:

[0018] S1. First, control the thrust seat to drive the extrusion rod to move to the outside of the passive seat, and keep a distance from the passive seat that exceeds the length of the aluminum embryo bar. Then transfer the heated aluminum embryo bar between the passive seat and the extrusion rod, control the thrust seat to drive the extrusion rod to move, and push the aluminum embryo bar into the inside of the extrusion cylinder.

[0019] S2. Under the extrusion force of the extrusion rod, the aluminum embryo bar flows through one side of the inside of mold II to the channel of mold I, and is extruded between mold II and mold I to form the required aluminum alloy extrusion parts. The aluminum alloy extrusion parts are pressed out from the outside of the positioning sleeve and transferred to the next processing equipment for subsequent processing.

[0020] S3. After an aluminum blank rod is used up, the hydraulic cylinder III drives the piston shaft to push the mounting seat to drive the cutter to move downward, and the aluminum alloy extrusion is cut on the outside of the positioning sleeve. Then the hydraulic cylinder II drives the piston shaft to drive the L-shaped plate II and the passive seat to move toward one side of the thrust seat. The thrust seat moves synchronously with the passive seat until the mold II at one end of the extrusion cylinder moves to one side of the discharge trough. Then, the channel on one side of the inside of the mold II for the aluminum blank rod to flow to the mold I is used, so that the mold II can drive the aluminum alloy extrusion remaining between the mold II and the mold I to move together.

[0021] S4. Inject air into the air inlet through the inflation pipe to increase pressure, push the push shaft in the air guide groove II to move, and one end of the push shaft can flow to the channel of the mold I through the aluminum embryo rod supply on one side of the inside of the mold II, push out the aluminum alloy extrusion parts remaining on the mold II, and the remaining aluminum alloy extrusion parts fall through the discharge chute and are recycled and reused.

[0022] S5. Hydraulic cylinder II drives the piston shaft to move the L-shaped plate II and the passive seat away from the side of the thrust seat until mold II and mold I are re-closed. At the same time, the thrust seat is controlled to drive the extrusion rod to move to the outside of the passive seat, ready to extrude the next aluminum blank.

[0023] S6. After the aluminum alloy extrusion parts are processed for a period of time, the piston shaft is driven by hydraulic cylinder III to drive the mounting seat to move further downward until the lubricating oil replenishing device moves to one side of mold I, and lubricating oil is injected into the positioning tube through the oil guide pipe. The internal oil pressure of the positioning tube increases, pushing the cylindrical piston toward mold I until the sides of the cylindrical piston and the oil outlet block are completely in contact with the sides of mold I. The lubricating oil pushes the piston slider to move and compresses the spring, and enters between mold II and mold I through the oil guide hole, guide groove, limit ring plate and micropores on the oil outlet block, and replenishes the lubricating oil in the mold cavity between mold II and mold I.

[0024] Beneficial effects of the present invention:

[0025] 1. The present application provides an aluminum alloy extrusion processing equipment and a processing technology thereof. An extrusion cylinder is added inside a fixed seat, mold I is installed in a positioning seat, and mold II is installed on one side of the extrusion cylinder. The aluminum embryo bar is extruded between mold II and mold I inside the extrusion cylinder to form the required aluminum alloy extrusion. Under the premise of not affecting the normal processing of the aluminum alloy extrusion, the formed aluminum alloy extrusion is cut off by a cutter, and then the hydraulic cylinder II drives the extrusion cylinder to drive mold II to move and separate from mold I. The aluminum alloy extrusion remaining on mold II is pushed out by the push shaft, so that before the next aluminum embryo bar is extruded, the aluminum embryo bar remaining in mold I and mold II is prevented from being hot-bonded to the mold due to the aluminum alloy raw material and the mold at high temperature, thereby effectively ensuring the processing quality of the aluminum alloy extrusion.

[0026] 2. The present application provides a processing equipment and a processing technology for aluminum alloy extrusion parts. The hydraulic cylinder II drives the extrusion cylinder to drive the mold II to move and separate from the mold I. After the aluminum alloy extrusion parts remaining on the mold II are pushed out by the push shaft, when the mold I closes the mold II again, the lubricating oil replenishing device can be used to replenish lubricating oil from between the mold I and the mold II, so that the contact surface between the mold I and the mold II and the aluminum embryo rod fluid can be fully lubricated, reducing the friction resistance of the subsequent aluminum embryo rod flowing through the mold I and the mold II after extrusion, making the extrusion process smoother, and further improving the quality of the processing and forming of the aluminum alloy extrusion parts.

After an aluminum blank is used up, the hydraulic cylinder III 22 drives the piston shaft to push the mounting seat 23 to drive the cutter 24 to move downward, and the aluminum alloy extrusion is cut on the outside of the positioning sleeve 7.

Under the extrusion force of the extrusion rod (18), the aluminum blank flows through one side of the interior of the die II (13) to the channel of the die I (9), and is extruded between the die II (13) and the die I (9) to form the desired aluminum alloy extrusion. The aluminum alloy extrusion is extruded from the outside of the positioning sleeve (7) and transferred to the next processing equipment for subsequent processing. S3, after an aluminum billet is used up, the hydraulic cylinder III (22) drives the piston shaft to push the mounting seat (23) to drive the cutter (24) to move downward, and the aluminum alloy extrusion is cut on the outer side of the positioning sleeve (7), and then the hydraulic cylinder II (14) drives the piston shaft to drive the L-shaped plate II (16) and the passive seat (15) to move toward one side of the thrust seat (17), and the thrust seat (17) moves synchronously with the passive seat (15) until the mold II (13) at one end of the extrusion cylinder (10) moves to one side of the discharge trough (101), and then the channel on one side of the inner side of the mold II (13) for the aluminum billet to flow to the mold I (9) is used, so that the mold II (13) can drive the aluminum alloy extrusion remaining between the mold II (13) and the mold I (9) to move together; S4, injecting air into the air inlet (182) through the air inlet pipe to increase pressure, pushing the push shaft (20) in the air guide groove II (191) to move, one end of the push shaft (20) can pass through the channel on one side of the inside of the mold II (13) for the aluminum embryo rod to flow to the mold I (9), and push out the aluminum alloy extrusion remaining on the mold II (13), and the remaining aluminum alloy extrusion falls through the discharge chute (101) and is recycled; S5, hydraulic cylinder II (14) drives the piston shaft to drive the L-shaped plate II (16) and the passive seat (15) to move away from the side of the thrust seat (17) until the mold II (13) and the mold I (9) are re-closed, and at the same time, the thrust seat (17) is controlled to drive the extrusion rod (18) to move to the outside of the passive seat (15) to prepare for extruding the next aluminum blank; S6.
