[0036] Example 2

[0037] like Figure 1-Figure 11As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a large-scale aluminum alloy single plate hot pressing forming device.

[0038] In this embodiment, the support seat 1, the pillar 7 and the outer shell 8 are fixedly connected to form an integral structure. The inner wall of the outer shell 8 and the outer wall of the electric heating plate 9 are in contact with each other. The electric heating plate 9 is located between the support assembly 6 and the pressing block 28 to ensure that the electric heating plate 9 can move smoothly in the outer shell 8. The electric heating plate 9 can preheat the aluminum plate placed on the support assembly 6 to ensure the subsequent hot pressing forming effect.

[0039] In this embodiment, the support assembly 6 includes a support plate 601 fixedly connected to the third connecting block 5, and a groove 602 and a mounting groove 603 are provided on the support plate 601. A magnetic block 604 is installed in the mounting groove 603, and a filling block 605 is fixedly provided on the magnetic block 604. The device can install the magnetic block 604 in the mounting groove 603 at the corresponding position, so that different numbers of filling blocks 605 are installed in different areas of the device, thereby changing the shape of the pressed area, and then adjusting the hot pressing forming effect of the device.

[0040] In this embodiment, the support plate 601, the first connecting block 3, the second connecting block 4 and the third connecting block 5 are fixedly connected to form an integral structure. When the first connecting block 3 rotates, it will drive the support plate 601 to rotate, thereby quickly switching the support structure of the device. The material of the support plate 601 is a magnetic metal material. The inner wall of the installation groove 603 and the outer wall of the magnetic block 604 fit together. The support plate 601 made of magnetic metal material can be adsorbed with the magnetic block 604, so that the magnetic block 604 can be stably installed.

[0041] In this embodiment, the installation grooves 603 are evenly distributed in the grooves 602 in the support plate 601, the depth of the grooves 602 is equal to the length of the filling blocks 605, and the support plate 601 is evenly distributed along the circumference of the second connecting block 4, ensuring that the filling blocks 605 can remain flush with the surface of the support plate 601 after installation, thereby ensuring the supporting effect of the device.

[0042] In this embodiment, the connecting component 10 includes a slide groove 1005 opened on the outer shell 8, and a first connecting block 1001 is slidably installed in the slide groove 1005. The first connecting block 1001 and the electric heating plate 9 are fixedly connected. A second connecting block 1002 is fixedly arranged on the first connecting block 1001, and a third connecting block 1003 is fixedly connected to the second connecting block 1002. A first spring 1004 is installed between the third connecting block 1003 and the outer shell 8. The electric heating plate 9 can slide in the outer shell 8 when the second connecting block 1002, the second connecting block 1002 and the third connecting block 1003 are pulled, and the first spring 1004 facilitates the subsequent resetting of the electric heating plate 9.

[0043] In this embodiment, the traction steel rope 11 is connected to the third connecting block 1003, and the electric heating plate 9 forms a sliding structure with the outer shell 8 through the first connecting block 1001, the second connecting block 1002, the third connecting block 1003 and the traction steel rope 11. When the traction steel rope 11 is pulled, it will drive the electric heating plate 9 to slide, so that the electric heating plate 9 can be automatically stored during the subsequent hot pressing forming, thereby enhancing the convenience of the device when used.

[0044] In this embodiment, the delayed ejection assembly 18 includes an outer cylinder 1801 fixedly connected to the fixed block 14, a second spring 1802 is installed in the outer cylinder 1801, a slide rod 1803 is fixedly connected below the second spring 1802, and the bottom of the slide rod 1803 is connected to the first supporting plate 19. The second spring 1802 facilitates the subsequent automatic movement of the slide rod 1803 to the top of the outer cylinder 1801 and reset after hot pressing for recycling.

[0045] In this embodiment, a docking groove 29 for docking with the docking rod 26 is provided on the top of the stud 27. The length and width of the docking rod 26 decrease from top to bottom. The studs 27 are evenly distributed on the second supporting plate 30. The docking rod 26 can dock with the docking groove 29 on the stud 27, so that the stud 27 can be screwed downward to facilitate the subsequent adjustment of the hot pressing molding structure of the device, so that the device can adapt to different needs for structural adjustment.

[0046] In this embodiment, the stud 27 forms a rotating structure with the connecting frame 21 through the docking rod 26 and the docking groove 29, and the pressure block 28 forms a sliding structure with the second supporting plate 30 through the docking rod 26 and the stud 27. The position and number of the pressure blocks 28 correspond to the position and number of the mounting grooves 603 in the upper support plate 601. When the stud 27 is screwed downward, it will drive the pressure block 28 to slide downward, ensuring that the pressure block 28 at the pressing position corresponds to the support plate 601 at the pressed position, thereby ensuring the hot pressing molding quality of the device.

[0047] Specifically, the present invention is a large-scale aluminum alloy single plate hot press forming device, first, as Figure 1 and Figure 4 As shown, the support seat 1 and the support column 7 are used to support the entire device, and the fixing block 14, the hydraulic rod 16 and the outer cylinder 1801 above the device are all fixed to the top of the wall. When the device is in use, it first passes through the structure of the support assembly 6 in the pressure position. Figure 5 and Figure 7-Figure 9As shown, the magnetic block 604 is installed in the installation groove 603 at the corresponding position, so that different numbers of filling blocks 605 are installed in different areas of the device, thereby changing the shape of the compressed area and adjusting the hot pressing effect of the device. Since the support plate 601 is made of magnetic metal material, and the inner wall of the installation groove 603 and the outer wall of the magnetic block 604 fit each other, the support plate 601 made of magnetic metal material can be adsorbed with the magnetic block 604, so that the magnetic block 604 is stably installed in the groove 602. After the compressed structure is adjusted, the pressing structure can be further adjusted to make the pressing structure consistent with the compressed structure. Fig.10 and Fig.11 As shown, the position of the second electric slide 23 is adjusted by the first electric slide 22, and the position of the electric push rod 24 and the second motor 25 is adjusted by the second electric slide 23, so as to change the position of the stud 27 corresponding to the docking rod 26. After the adjustment is completed, the electric push rod 24 is extended so that the docking rod 26 docks with the docking groove 29 on the stud 27, and the docking rod 26 is driven to rotate by the second motor 25, and the docking rod 26 drives the stud 27 to rotate, and the stud 27 drives the pressing block 28 to slide under the second supporting plate 30, so as to change the height of the pressing block 28 in the corresponding area, so that the device can change the stamping structure according to the shape of the pressed area, thereby changing the stamping effect of the aluminum plate.

[0048] like Figure 1-Figure 6 As shown, the hydraulic rod 16 is extended to drive the second connecting plate 17 to move downward. When the second connecting plate 17 moves, it pulls the traction steel rope 11, so that the traction steel rope 11 pulls the third connecting block 1003 on the connecting assembly 10 under the guidance of the first guide wheel 12 and the second guide wheel 13. Since the first connecting block 1001, the second connecting block 1002, the third connecting block 1003 and the electric heating plate 9 are a whole, the electric heating plate 9 shrinks into the shell 8, and the first spring 1004 is compressed until the bottom of the hydraulic rod 16 contacts the first supporting plate 19, realizing the hot pressing process. The function of automatically storing the electric heating plate 9 in the hydraulic rod 16 is that the second connecting plate 17 at the bottom of the hydraulic rod 16 can press the first supporting plate 19 downward. When the first supporting plate 19 moves downward, it will drive the first connecting rod 20, the connecting frame 21, the second supporting plate 30 and the pressing block 28 to move downward. When the pressing block 28 moves downward, it will abut against the aluminum plate, thereby cooperating with the support plate 601 so that the aluminum plate can be hot-pressed into a suitable shape. The first spring 1004 can automatically reset the electric heating plate 9 when the hydraulic rod 16 is shortened, and the second spring 1802 in the outer cylinder 1801 can automatically reset the sliding rod 1803. Subsequently, the first motor 2 can be used to drive the first connecting block 3, the second connecting block 4, the third connecting block 5 and the supporting plate 601 to rotate. When the supporting plate 601 rotates, it can change the pressure structure and can also remove the aluminum plate that has been hot-pressed.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
