[0003] After searching, the Chinese patent publication number is CN217512731U, which discloses an automatic aluminum alloy extrusion forming device, including a processing back plate, a rotating base plate, an extrusion bottom die, a lifting control plate, an extrusion top die, a rotation control component and a demolding component. A rotating hole is opened on one side of the processing back plate, and the rotating base plate is arranged on one side of the processing back plate. A rotating seat is fixedly installed on one side of the rotating base plate, and the rotating seat is rotatably connected in the rotating hole. The extrusion bottom die is fixedly installed on the top of the rotating base plate. The above patent can automatically unload aluminum alloy profiles, and can also demold the aluminum alloy workpiece while discharging. The steps are simple and the processing efficiency is improved.

[0029] The present invention will be further described below with reference to the accompanying drawings. Example

[0030] like Figures 1-8As shown, an aluminum alloy extrusion forming device includes a body 1, an extrusion mechanism 4 is provided on the left side of the top of the body 1, a feeding mechanism 5 is provided on the right side of the top of the body 1 and is located symmetrically with the extrusion mechanism 4, a rotating shaft 101 is connected to the middle of the body 1 through a bearing, the top of the rotating shaft 101 extends out of the body 1 and is welded with a rotating plate 102, both ends of the top of the rotating plate 102 are connected to the lower mold 3 through bolts, the top of the body 1 and the front side of the rotating shaft 101 are connected to a pressure top plate 8 by screws, the top of the body 1 and the front side of the pressure top plate 8 are connected to a blocking rod 9 by screws, a spiral groove column 6 fixedly connected to the rotating shaft 101 is provided inside the body 1, a lever mechanism 7 for driving the spiral groove column 6 to rotate is provided inside the body 1, and the top of the lever mechanism 7 is fixedly connected to the extrusion mechanism 4.

[0031] When the pressing plate 303 is pressed down, the pressing plate 302 is pressed down, and the pressing plate 303 is pressed down, so that the pressing plate 303 is pressed down and the pressing plate 303 is pressed down, so that the pressing plate 303 is pressed down and the pressing plate 303 is pressed down.

[0032] In this embodiment, the unloading mechanism 5 includes a second bracket 501, which is connected to the top of the machine body 1 by bolts. A material box 502 is welded on one side of the second bracket 501 near the center of the machine body 1, and aluminum alloy material plates to be extruded are stacked in the material box 502. A guide plate 503 is fixedly connected to the rear side of the bottom end of the material box 502. An avoidance groove is provided in the middle of the guide plate 503 for allowing the push plate 305 to pass through. The guide plate 503 is arc-shaped and the center of the circle coincides with the axis of the rotating shaft 101. A notch is provided on the front side of the bottom end of the material box 502 for allowing the push plate 305 to enter the interior of the material box 502. When the lower mold 3 rotates and passes from under the material box 502, the push plate 305 enters the material box 502 from the notch and pushes the lowest aluminum alloy plate backwards. The aluminum alloy plate enters the guide plate 503, and the push plate 305 continues to move in the avoidance groove, pushing the aluminum alloy plate out of the guide plate 503 and falling into the lower mold 3.

[0033] In this embodiment, the extrusion mechanism 4 includes a first bracket 401, which is connected to the top of the body 1 by bolts. The top of the first bracket 401 is connected to a hydraulic cylinder 402 by bolts. The bottom of the output shaft of the hydraulic cylinder 402 is fixedly connected to a lifting plate 403. The lifting plate 403 is slidably connected to the first bracket 401 through a slide groove, and the bottom of the lifting plate 403 is fixedly connected to an upper mold 404.

[0034] In this embodiment, two straight grooves 601 and two spiral grooves 602 are provided on the spiral groove column 6 in the vertical direction. The straight grooves 601 and the spiral grooves 602 are connected to each other. The depth of the top of the straight groove 601 is greater than the depth of the top of the spiral groove 602, so that the lever mechanism 7 rises to the top along the spiral groove 602 and enters the straight groove 601. The depth of the bottom of the straight groove 601 is less than the depth of the bottom of the spiral groove 602, so that the lever mechanism 7 moves down to the bottom along the straight groove 601 and enters the spiral groove 602, so that the spiral groove column 6 is driven to rotate 180° counterclockwise during the rising process of the lever mechanism 7, and the spiral groove column 6 is not driven to rotate during the downward movement of the lever mechanism 7.

[0035] In this embodiment, the lever mechanism 7 includes a cross bar 701, and a driving rod 702 is slidably connected to the inner side of the cross bar 701 near the end of the spiral groove column 6. The driving rod 702 can extend into the straight groove 601 and the spiral groove 602. The spiral groove column 6 is rotated by the cooperation between the driving rod 702 and the spiral groove 602. A pressure spring 703 is fixedly connected between the driving rod 702 and the inner wall of the cross bar 701. The pressure spring 703 is in a compressed state. Due to the depth difference between the straight groove 601 and the spiral groove 602, the pressure spring 703 is used to press the straight groove 601 and the spiral groove 602. This allows the driving rod 702 to switch smoothly between the straight groove 601 and the spiral groove 602. A vertical rod 704 is welded to the end of the horizontal rod 701 away from the spiral groove column 6. The top of the vertical rod 704 extends out of the body 1 and is connected to the bottom of the lifting plate 403 by screws. When the lifting plate 403 moves down, the vertical rod 704 and the driving rod 702 move down, and the driving rod 702 moves from top to bottom in the straight groove 601. When the lifting plate 403 moves up, the driving rod 702 moves from bottom to top in the spiral groove 602, thereby driving the spiral groove column 6 to rotate.

[0036] In this embodiment, the pressure-bearing top plate 8 is arc-shaped, and the pressure-bearing top plate 8 is coaxial with the rotating shaft 101. The pressure-bearing top plate 8 is located on the movement trajectory of the push rod 302. The pressure-bearing top plate 8 is higher in the middle and lower at both ends. When the push rod 302 makes a circular motion, the push rod 302 moves from the bottom end of the pressure-bearing top plate 8 to the top end of the pressure-bearing top plate 8, so that the push rod 302 drives the stripping plate 301 to move upward to eject the aluminum alloy part out of the lower mold 3, and then the push rod 302 continues to move from the top end of the pressure-bearing top plate 8 to the bottom end, and under the action of the reset spring 304, the stripping plate 301 and the push rod 302 are reset.

[0037] In this embodiment, an inclined discharge plate 2 is fixedly connected to the top front end of the machine body 1. The discharge plate 2 is located in front of the pressure-bearing top plate 8 and on the left side of the extrusion mechanism 4 of the blocking rod 9. When the lower mold 3 located below the extrusion mechanism 4 rotates counterclockwise, automatic demolding is achieved. The aluminum alloy parts after demolding are blocked by the blocking rod 9, so that the aluminum alloy parts fall onto the discharge plate 2 for automatic discharge, which is convenient for collection by the staff.

[0038] Working principle: During extrusion molding, the hydraulic cylinder 402 drives the lifting plate 403 to move downward, so that the upper mold 404 moves downward and merges with the lower mold 3 to extrude the aluminum alloy sheet in the lower mold 3. During the downward movement of the lifting plate 403, the vertical rod 704 is driven downward, and the vertical rod 704 drives the cross bar 701 to move downward. The cross bar 701 drives the driving rod 702 to move from top to bottom in the straight groove 601 of the spiral groove column 6. When the driving rod 702 moves to the lowest end of the straight groove 601, due to the certain depth difference between the straight groove 601 and the spiral groove 602, the driving rod 702 is pushed forward by the top pressure spring 703. The screw thread 402 is pressed into the spiral groove 602, and the spiral groove column 6 does not rotate during this process. After extrusion, the hydraulic cylinder 402 retracts to drive the lifting plate 403 to move upward, thereby moving the driving rod 702 upward. The driving rod 702 moves from the bottom end of the spiral groove 602 to the top end. During this process, the driving rod 702 drives the spiral groove column 6 to rotate 180° counterclockwise. When the driving rod 702 moves to the top end of the spiral groove 602, the driving rod 702 enters the straight groove 601 again, and so on. As a result, the spiral groove column 6 does not rotate during the downward extrusion process of the extrusion mechanism 4, and the spiral groove column 6 rotates 180° counterclockwise during the upward process of the extrusion mechanism 4.

[0039] During the rotation of the spiral groove column 6, the rotating shaft 101 and the rotating plate 102 rotate, and the rotating plate 102 drives the two lower molds 3 to rotate counterclockwise to interchange positions. When the lower mold 3 located below the extrusion mechanism 4 rotates counterclockwise and passes above the pressure-bearing top plate 8, the ejector rod 302 contacts the pressure-bearing top plate 8, and the ejector rod 302 rises along the pressure-bearing top plate 8. The ejector rod 302 drives the stripping plate 301 to move up and eject the formed aluminum alloy part. During this process, the return spring 304 is compressed, and when the ejector rod 302 moves to the highest point of the pressure-bearing top plate 8, the top surface of the stripping plate 301 is flush with the top surface of the lower mold 3. At this time, the formed aluminum alloy part is located above the discharge plate 2, and the lower mold 3 continues to move. The blocking rod 9 blocks the aluminum alloy part so that it will not move with the lower mold 3, thereby causing the aluminum alloy part to fall on the discharge plate 2 to achieve automatic discharge;

[0040] During the discharge process, the lower die 3 located below the discharge mechanism 5 performs a counterclockwise circular motion. During the motion, the push plate 305 enters the material box 502 from the notch at the bottom of the material box 502 and pushes the lowermost aluminum alloy sheet backward onto the guide plate 503. The push plate 305 passes through the middle of the guide plate 503, causing the aluminum alloy sheet to move along the guide plate 503 and finally fall into the lower die 3.

[0041] When the lifting plate 403 rises to the upper limit position, the spiral groove column 6 rotates 180 degrees, the two lower molds 3 exchange positions and complete the discharge and unloading operations respectively, and then the upper mold 404 can be immediately moved down again for extrusion molding. This eliminates the intermediate waiting link of manual discharge, realizes continuous extrusion molding, and further improves production efficiency.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
