[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-Figure 8 A stable pressing device for producing high-temperature resistant composite panels includes a workbench 1, a supporting structure 2, a pressing structure 3 and a limiting structure 4. The interior of the supporting structure 2 includes a driving cylinder A201 and a slide 202. The number of slides 202 is two and they are symmetrically arranged. The output shaft of the driving cylinder A201 is fixedly installed with a lifting frame 203, and the inner wall of the lifting frame 203 is fixedly installed with a driving shaft 204. The top of the slide 202 is symmetrically provided with a slide groove 205, and the top of the slide 202 is provided with an articulated seat 206. The bottom of the articulated seat 206 is symmetrically fixedly installed with a slider 207, and the slider 207 is slidably installed on the inner wall of the slide groove 205. An elastic metal plate 208 is fixedly installed between the outer walls of the two articulated seats 206, and the inner wall of the elastic metal plate 208 is slidably connected to the outer wall of the driving shaft 204.

[0031] The interior of the pressing structure 3 includes a driving cylinder B301, the output shaft of the driving cylinder B301 is fixedly installed with a moving seat 302, the inner wall of the moving seat 302 is symmetrically rotatably installed with a rotating plate 303, an arc-shaped telescopic rod 304 and an arc-shaped elastic member 305 are fixedly installed between the rotating plate 303 and the outer wall of the moving seat 302, the arc-shaped elastic member 305 is sleeved on the outer side of the arc-shaped telescopic rod 304, one end of the rotating plate 303 is fixedly installed with a mounting seat 306, and the inner wall of the mounting seat 306 is rotatably installed with a pressing roller 307.

[0032] In this embodiment, the driving cylinder A201 is started, and the driving cylinder A201 will drive the lifting frame 203 to move up and down. When the lifting frame 203 is moved up and down, the driving shaft 204 will drive the middle part of the elastic metal plate 208 to adjust the height. The two ends of the elastic metal plate 208 can only move horizontally under the cooperation of the slide groove 205, the slider 207 and the hinge seat 206, and cannot move vertically. Therefore, when the driving shaft 204 drives the elastic metal plate 208 to move, the curvature of the elastic metal plate 208 will change.

[0033] Start the driving cylinder B301, and the driving cylinder B301 drives the moving seat 302 to rise and fall. When the moving seat 302 descends, the pressing roller 307 will conflict with the curved composite plate. After the conflict occurs, the two rotating plates 303 will rotate to both sides, and the two pressing rollers 307 will rotate to both sides to roll and extrude the curved composite plate. At this time, the arc-shaped elastic member 305 is in an extrusion state. When the moving seat 302 rises, the rotating plate 303 will reverse and reset under the action of the reverse elastic force of the arc-shaped elastic member 305. At this time, the two pressing rollers 307 will roll and extrude the curved composite plate in the opposite direction, and the pressing work of the curved composite plate is completed in this reciprocating manner.

[0034] Specifically, the interior of the limiting structure 4 includes two symmetrically arranged positioning shafts 401, the outer wall of the positioning shaft 401 is rotatably installed with a rotating block 402, the outer wall of the rotating block 402 is fixedly installed with a threaded rod A403, the outer wall of the threaded rod A403 is threadedly installed with an adjusting column 404, the inner wall of the adjusting column 404 is threadedly installed with a threaded rod B405, and the inner wall of one end of the threaded rod B405 is fixedly installed with a positioning plate 406.

[0035] In this embodiment, the curved composite sheet to be pressed is stacked on top of the elastic metal plate 208, and then the adjusting column 404 is rotated to adjust the extension length of the threaded rod B405 so that the two positioning plates 406 are respectively against the two ends of the curved composite sheet, thereby positioning the curved composite sheet to prevent the curved composite sheet from shifting during the pressing work.

[0036] Specifically, vertical rods 5 are fixedly installed at the four corners of the top of the workbench 1 , and a top plate 6 is fixedly installed between the tops of the four vertical rods 5 .

[0037] In this embodiment, the top plate 6 is connected to the workbench 1 by the vertical rod 5 , so as to fix the top plate 6 . The top plate 6 is located above the workbench 1 , providing conditions for the installation of the pressing structure 3 .

[0038] Specifically, the driving cylinder A201 is fixedly installed at the bottom of the workbench 1, the slide 202 is fixedly installed at the top of the workbench 1, the two positioning shafts 401 are respectively fixedly installed between the inner walls of the two corresponding vertical rods 5, and the two positioning plates 406 are overlapped on the top of the elastic metal plate 208.

[0039] In this embodiment, the driving cylinder A201 is fixed to the workbench 1 to provide a fulcrum for the driving cylinder A201 so that the driving cylinder A201 can provide power for the operation of the device. The slide 202 is connected to the workbench 1 to fix the slide 202. The two positioning shafts 401 are respectively located between the two vertical rods 5 on both sides, so that the limiting structure 4 can limit the two ends of the composite plate.

[0040] Specifically, a support A7 is fixedly installed at the bottom of the workbench 1, the inner wall of the support A7 is fixedly connected to the outer wall of the driving cylinder A201, and a reinforcing triangle plate 8 is symmetrically fixedly installed between the output shaft of the driving cylinder A201 and the outer wall of the lifting frame 203.

[0041] In this embodiment, the driving cylinder A201 is reinforced by the support A7 to increase the stability of the driving cylinder A201 during operation, and the reinforcing triangle plate 8 is used to reinforce the output shaft of the driving cylinder A201 and the lifting frame 203.

[0042] Specifically, a support B9 is fixedly installed on the top of the top plate 6, a driving cylinder B301 is fixedly installed on the top of the support B9, a stabilizing plate 10 is fixedly installed between the output shaft of the driving cylinder B301 and the inner wall of the support B9, a stabilizing seat 11 is fixedly installed on the top of the support B9, and the inner wall of the stabilizing seat 11 is fixedly connected to the outer wall of the driving cylinder B301.

[0043] In this embodiment, the support B9 is used to fix the driving cylinder B301, the stabilizing plate 10 increases the stability of the output shaft of the driving cylinder B301, and the stabilizing seat 11 further reinforces the driving cylinder B301.

[0044] Specifically, support legs 12 are fixedly installed at the four corners of the bottom of the workbench 1 , support feet 13 are fixedly installed at the bottom of the support legs 12 , and a cross plate 14 is fixedly installed between the outer walls of two corresponding support legs 12 .

[0045] In this embodiment, the support legs 12 support the device so that the device is at a suitable working height. The support feet 13 increase the contact area with the ground and increase the overall stability of the equipment. The cross plate 14 connects two support legs 12 that are far apart to increase the stability of the support legs 12.

[0046] Specifically, a receiving block 15 is symmetrically fixedly installed on the outer wall of the movable seat 302, a positioning column 16 is fixedly installed on the top of the receiving block 15, the outer wall of the positioning column 16 is slidably connected to the inner wall of the top plate 6, a support plate 17 is fixedly installed on the bottom of the movable seat 302, and an arc-shaped limiting column 18 is symmetrically fixedly installed between the outer wall of the support plate 17 and the bottom of the movable seat 302, and the outer walls of the two arc-shaped limiting columns 18 are slidably connected to the inner walls of the two rotating plates 303 respectively.

[0047] In this embodiment, the positioning column 16 limits the movable seat 302 to ensure that the movable seat 302 can move along a preset direction when lifting, and the arc-shaped limiting column 18 limits the rotating plate 303 to increase the stability of the rotating plate 303 when rotating.

[0048] The working principle and use process of the present invention are as follows: before the pressing work is performed, the device is adjusted first, and the driving cylinder A201 is started to drive the lifting frame 203 to move up and down. When the lifting frame 203 is moved up and down, the driving cylinder A201 is driven to bend the elastic metal plate 208 through the driving shaft 204. When the elastic metal plate 208 is bent to a suitable curvature, the driving cylinder A201 is stopped, and the elastic metal plate 208 is kept at a suitable curvature. Then, the curved composite plate to be pressed is stacked on the elastic metal plate 208. After the curved composite plate is placed, the adjusting column 404 is rotated to change the curvature. The extended length of the variable threaded rod B405 is changed so that the two positioning plates 406 are pressed against the two ends of the curved composite sheet, and finally the driving cylinder B301 is started. The driving cylinder B301 drives the moving seat 302 to rise and fall. When the moving seat 302 descends, the two pressing rollers 307 come into conflict with the curved composite sheet, and the two pressing rollers 307 will rotate to both sides, thereby rolling and squeezing the curved composite sheet from the middle position to both sides. When the moving seat 302 rises, the two pressing rollers 307 will reset and move to the middle to extrude the curved composite sheet, and the pressing work of the curved composite sheet is realized in this reciprocating manner.

[0049] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
