Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, specifically an aluminum profile extrusion die. Background Technology

[0002] Currently, in the processing of aluminum alloy sheets, it is often necessary to heat the billet to a temperature above the recrystallization temperature of the metal before extruding the raw materials such as aluminum ingots or aluminum billets through an extrusion press.

[0003] Existing aluminum profile extrusion dies often result in the aluminum profile workpiece adhering to the inner wall of the die after extrusion, hindering workers from easily removing the workpiece and making the removal process cumbersome. Furthermore, since the existing dies are fixed on the processing table, it is inconvenient for operators to eject the workpiece from the die. Therefore, those skilled in the art have proposed an aluminum profile extrusion die to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum profile extrusion die to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aluminum profile extrusion die includes a processing table, a support rod installed at a corner of the processing table, and a top plate installed on the top of the support rod; two support seats are installed on the processing table, symmetrically arranged on the processing table, and a rotating shaft is rotatably mounted on the support seat, the rotating shaft being fixedly connected to a lower die; a cavity is formed inside the lower die; a fixing block is installed on the processing table, and a support plate that mates with the cavity is installed on the fixing block; two vertically arranged baffles are installed on the processing table, symmetrically arranged on the processing table; and the die further includes:

[0007] A drive assembly is mounted on a machining table and is used to drive the rotating shaft to rotate.

[0008] As a further embodiment of this utility model: a support frame is installed on the processing table.

[0009] As a further improvement of this utility model, the two sides of the tray are arc-shaped.

[0010] As a further embodiment of this utility model: the drive assembly includes transmission boxes installed on both sides of the processing table and connected to the support base. A first bevel gear is installed at one end of the rotating shaft that passes through the transmission box. A transmission shaft is rotatably arranged inside the transmission box. A second bevel gear that meshes with the first bevel gear is installed on the transmission shaft. A motor connected to the transmission shaft is installed on one of the transmission boxes.

[0011] As a further embodiment of this utility model: a hydraulic rod is installed on the top plate, the hydraulic rod is fixedly connected to the upper mold, and a punch is provided on the upper mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the heated aluminum ingot raw material is fed into the concave mold of the lower mold, and then the hydraulic rod is activated. Driven by the hydraulic rod, the upper mold descends, and the punch of the upper mold enters the concave mold of the lower mold. After the upper and lower molds are closed, and the aluminum ingot is extruded and formed, the hydraulic rod retracts to drive the upper mold to rise and separate from the lower mold. At this time, the drive assembly drives the rotating shaft to rotate 90 degrees clockwise until the lower mold rotates to contact the baffle. At this time, the support plate originally located in the inner cavity will disengage from the inner cavity, and the lower mold will also rotate to the vertical direction, which makes it convenient for the worker to eject the formed aluminum profile workpiece from the inner cavity on the back of the lower mold. This improves the convenience of the worker when picking up the workpiece. The ejected formed aluminum profile workpiece will also be directly separated from the lower mold and fall down, so there is no need to transfer it out of the lower mold after ejecting the formed aluminum profile workpiece, making it more convenient to use.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Please see Figures 1-4 An aluminum profile extrusion die includes a processing table 1, a support rod 2 installed at a corner of the processing table 1, and a top plate 3 installed on the top of the support rod 2; two support seats 4 are installed on the processing table 1, symmetrically arranged; a rotating shaft 5 is rotatably mounted on the support seat 4, and the rotating shaft 5 is fixedly connected to a lower die 6; a cavity 7 is opened in the lower die 6, and an inner cavity 9 is opened in the cavity 7; a fixing block 11 is installed on the processing table 1, and a support plate 10 that cooperates with the inner cavity 9 is installed on the fixing block 11; two vertical baffles 15 are installed on the processing table 1, symmetrically arranged; a hydraulic rod 12 is installed on the top plate 3, and the hydraulic rod 12 is fixedly connected to an upper die 13; a punch 14 is provided on the upper die 13; and the die further includes:

[0020] A drive assembly is mounted on the processing table 1 and is used to drive the rotating shaft 5 to rotate.

[0021] In use, the heated aluminum ingot is fed into the concave mold 7 of the lower mold 6. Then, the hydraulic rod 12 is activated, and the upper mold 13 descends under the drive of the hydraulic rod 12. The punch 14 of the upper mold 13 enters the concave mold 7 of the lower mold 6. After the upper mold 13 and the lower mold 6 are closed, and the aluminum ingot is extruded and formed, the hydraulic rod 12 retracts, driving the upper mold 13 to rise and separate from the lower mold 6. At this time, the drive assembly drives the rotating shaft 5 to rotate 90 degrees clockwise until the lower mold 6 rotates to contact the baffle 15. At this time, the support plate 10, which was originally located in the inner cavity 9, will disengage from the inner cavity 9, and the lower mold 6 will also rotate to the vertical direction, thus facilitating... The worker ejects the formed aluminum profile workpiece from the inner cavity 9 on the back of the lower mold 6, which improves the convenience of the worker when picking up the workpiece. The ejected formed aluminum profile workpiece will also be directly separated from the lower mold 6 and fall off, so there is no need to transfer the formed aluminum profile workpiece out of the lower mold 6 after ejection. It is more convenient to use. After the aluminum profile workpiece formed in the concave mold 7 is ejected, the output shaft of the motor 20 rotates in the opposite direction, thereby driving the rotating shaft 5 to rotate 90 degrees in the opposite direction through the meshing first bevel gear 17 and second bevel gear 18, so that the lower mold 6 rotates to a horizontal state, and the support plate 10 is inserted into the inner cavity 9 to realize the reset of the lower mold 6, ready for the next extrusion molding.

[0022] In one embodiment, a support frame 8 is installed on the processing table 1.

[0023] The bottom of the lower mold 6 is supported by the support frame 8, which facilitates the upper mold 13 to press the lower mold 6, and the lower mold 6 is in a horizontal state at this time.

[0024] In one embodiment, the two sides of the tray 10 are arc-shaped, and the two sides of the inner wall of the inner cavity 9 are also arc-shaped.

[0025] The arc-shaped design of the support plate 10 and the inner cavity 9 on both sides facilitates the insertion of the support plate 10 into the inner cavity 9 during the rotation of the lower mold 6 around the rotating shaft 5, while also preventing the support plate 10 from protruding from the die 7 and affecting the extrusion molding of the aluminum profile.

[0026] In one embodiment, the drive assembly includes a transmission box 16 mounted on both sides of the processing table 1 and connected to the support base 4. A first bevel gear 17 is installed at one end of the rotating shaft 5 that passes through the transmission box 16. A transmission shaft 19 is rotatably arranged inside the transmission box 16. A second bevel gear 18 that meshes with the first bevel gear 17 is mounted on the transmission shaft 19. A motor 20 connected to the transmission shaft 19 is installed on one of the transmission boxes 16.

[0027] When the drive shaft 5 rotates and drives the lower mold 6 to rotate 90 degrees, the motor 20 is started by the external controller. The first bevel gear 17 and the second bevel gear 18 meshing together can drive the drive shaft 5 to rotate, thereby driving the lower mold 6 to rotate 90 degrees.

[0028] In use, this invention involves feeding heated aluminum ingots into the concave mold 7 of the lower mold 6, then activating the hydraulic rod 12. Driven by the hydraulic rod 12, the upper mold 13 descends, and the punch 14 of the upper mold 13 enters the concave mold 7 of the lower mold 6. After the upper mold 13 and lower mold 6 are closed, and the aluminum ingot is extruded, the hydraulic rod 12 retracts, driving the upper mold 13 to rise and separate from the lower mold 6. At this point, the drive assembly drives the rotating shaft 5 to rotate 90 degrees clockwise until the lower mold 6 contacts the baffle 15. Simultaneously, the support plate 10, originally located within the inner cavity 9, disengages from the inner cavity 9, and the lower mold 6 rotates to a vertical position. The process allows workers to easily eject the formed aluminum profile workpiece from the inner cavity 9 on the back of the lower mold 6, thus improving the convenience of workpiece removal. The ejected aluminum profile workpiece also separates directly from the lower mold 6 and falls off, eliminating the need to transfer it out of the lower mold 6 after ejection. This makes it more convenient to use. After the aluminum profile workpiece formed in the concave mold 7 is ejected, the output shaft of the motor 20 rotates in the reverse direction, thereby driving the rotating shaft 5 to rotate 90 degrees in the reverse direction through the meshing first bevel gear 17 and second bevel gear 18. This causes the lower mold 6 to rotate to a horizontal position, and the support plate 10 is inserted into the inner cavity 9, realizing the reset of the lower mold 6 and preparing it for the next extrusion molding.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
