Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel processing technology, and in particular to a cold press for honeycomb panel processing. Background Technology

[0002] Aluminum honeycomb panels consist of two aluminum plates, upper and lower, and an aluminum honeycomb core in the middle. This structure is similar to the load transfer method of an I-beam. The upper and lower panels mainly bear in-plane tensile and compressive stresses and shear stresses, while the aluminum honeycomb core mainly bears transverse shear stresses. In the manufacturing process of aluminum honeycomb panels, the selection of materials is crucial. Due to their excellent mechanical properties and machinability, aluminum alloy sheets are often used as the material for the upper and lower panels. Cold pressing is a pressure forming method that uses a stamping die on a press to apply pressure to sheet or shaped material at room temperature, causing it to undergo plastic deformation or separation, thereby obtaining parts with the required shape and size.

[0003] In the prior art, Chinese Patent Publication No. CN118905077A discloses a cold-pressing process for aluminum honeycomb panels, including the following steps: S1, Material preparation: First, two thin aluminum alloy panels and an aluminum honeycomb core need to be prepared, ensuring that their size, shape, and quality meet production requirements. By installing a cold-pressing protective mechanism between the base and the upper cold-pressing plate, the base plate is guaranteed to support the upper material plate while being pressed by the upper cold-pressing plate, ensuring buffering of the base and preventing damage to the base caused by long-term pressing force of the upper cold-pressing plate. With the setting of multi-point pressure components, the pressure can be evenly applied to all parts of the aluminum honeycomb panel, meeting the downward pressure of the upper cold-pressing plate, and fully pressing the material plate between the upper cold-pressing plate and the base, providing bidirectional pressure to the material plate, making the texture and strength of the plate uniform at both ends, effectively reducing or avoiding the situation where the glue is not completely cured in some areas, forming bubbles or voids.

[0004] However, in actual use, this utility model requires multiple sheets to be stacked during cold pressing. It is not convenient to align the edges of the sheets when stacking them. When misalignment occurs between the sheets, uneven stress will occur, which will affect the effect of cold pressing. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a cold press for processing honeycomb panels, which has the effect of making it easier for the stacked panels to be pressed down by the lower press table, resulting in more uniform force distribution.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cold press for processing honeycomb panels, including a press table, with supports fixedly connected to both sides of the press table, a lifting frame slidably connected to the inner wall of the supports, a first cylinder fixedly connected to one side of the lifting frame, a first telescopic rod fixedly connected to the output end of the first cylinder, a movable plate movably mounted on one end of the first telescopic rod, a second cylinder fixedly connected to both sides of the movable plate, a second telescopic rod fixedly connected to the output end of the second cylinder, a positioning plate fixedly connected to one end of the second telescopic rod, and a lower press table provided on the top of the press table.

[0007] By adopting the above technical solution, during cold pressing, the plates are stacked on top of the pressing table, with the plates placed in the center of the pressing table. Then, the first cylinder is activated, driving the first telescopic rod to extend, thereby moving the plate. One side of the positioning plate is close to the side of the plate, and the two sets of positioning plates move towards the middle, thus pushing the two sides of the plate to align. At this time, the second cylinder is activated, driving the second telescopic rod to retract, moving the positioning plate. The right angle of the positioning plate pushes the other two sides of the plate to align. The positioning plate adjusts its position according to the length and width of the plate, thereby aligning the four sides of the plate. When the plates are stacked high, the lifting frame can be raised and lowered, driving the positioning plate to rise. This has a wider range of applications. The neatly stacked plates are easier for the lower pressing table to press down, making the force more even and preventing misalignment.

[0008] A further feature of this invention is that a fixing plate is fixedly connected to the inner wall of the bracket, and a third cylinder is fixedly connected to the top of the fixing plate.

[0009] By adopting the above technical solution, the fixed plate supports the third cylinder, and the number of the third cylinder is two, symmetrically distributed on both sides.

[0010] A further feature of this invention is that a third telescopic rod is fixedly connected to the output end of the third cylinder, and the bottom of the third telescopic rod is fixedly connected to the lifting frame.

[0011] By adopting the above technical solution, the lifting height of the lifting frame can be controlled by the extension and retraction of the third telescopic rod, making the lifting and retraction flexible.

[0012] A further feature of this invention is that a buffer groove is provided on the inner wall of the lifting frame, and a slider is fixedly connected to the outer surface of the lifting frame.

[0013] By adopting the above technical solution, the buffer groove facilitates the up-and-down sliding of the slider, thus supporting the lifting frame.

[0014] A further feature of this invention is that a connecting plate is fixedly connected to one end of the first telescopic rod, and a mounting plate is fixedly connected to one end of the movable plate.

[0015] By adopting the above technical solution, the connecting plate and the mounting plate are the same in shape and size, and they are matched during installation.

[0016] A further feature of this invention is that the mounting plate is internally threaded with bolts, and the connecting plate has internally threaded holes.

[0017] By adopting the above technical solution, the bolt passes through the threaded hole for connection and installation.

[0018] A further feature of this invention is that the positioning plate is L-shaped, and a reinforcing layer is fixedly connected to the inner wall of the positioning plate.

[0019] By adopting the above technical solution, the reinforcement layer can prevent the positioning plate from easily deforming and keep its shape unchanged.

[0020] A further feature of this invention is that the number of positioning plates is four, and the four positioning plates are divided into two groups of two.

[0021] By adopting the above technical solution, the two sets of positioning plates are symmetrically distributed, resulting in a strong positioning effect.

[0022] A further feature of this invention is that a crossbeam is fixedly connected to the top of the bracket, and the number of brackets is two.

[0023] By adopting the above technical solution, the crossbeam connects the two supports, thereby reinforcing the supports.

[0024] A further feature of this invention is that the positioning plate is made of metal, and the outer surface of the reinforcing layer is coated with a wear-resistant coating.

[0025] By adopting the above technical solution, the wear-resistant coating can prevent wear and ensure the flatness of the positioning surface.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the coordinated arrangement of a pressing table, a support, a lifting frame, a first cylinder, a first telescopic rod, a moving plate, a second cylinder, a second telescopic rod, a positioning plate, and a lower pressing table, enables the device to stack plates on top of the pressing table during cold pressing, with the plates placed in the center of the pressing table. Then, the first cylinder is activated, driving the first telescopic rod to extend, thereby moving the moving plate. One side of the positioning plate approaches the side of the plate, and the two sets of positioning plates move towards the center, thus pushing the sides of the plate to align. At this time, the second cylinder is activated, driving the second telescopic rod to retract, moving the positioning plate. The right-angled angle of the positioning plate pushes the other sides of the plate to align. The positioning plate adjusts its position according to the length and width of the plate, thus aligning the four sides of the plate. When the plates are stacked high, the lifting frame can rise and fall, driving the positioning plate upwards. This expands the applicability range. The neatly stacked plates facilitate the downward pressing of the lower pressing table, making the force more even and preventing misalignment.

The reinforcing layer prevents the positioning plate from easily deforming, keeping its shape unchanged. The wear-resistant coating prevents wear and ensures the flatness of the positioning surface.

[0036] A cold press for processing honeycomb panels includes the following embodiments:

[0037] Example 1:

[0038] Reference Figure 1-4 The pressing platform 1 is fixedly connected to both sides of the support 2. The inner wall of the support 2 is slidably connected to the lifting frame 3. The lifting frame 3 is fixedly connected to one side of the first cylinder 4. The output end of the first cylinder 4 is fixedly connected to the first telescopic rod 5. The first telescopic rod 5 is movably installed with a moving plate 6 at one end. The moving plate 6 is fixedly connected to both sides of the second cylinder 7. The output end of the second cylinder 7 is fixedly connected to the second telescopic rod 8. The second telescopic rod 8 is fixedly connected to one end of the second telescopic rod 8. The pressing platform 10 is provided on the top of the pressing platform 1.

[0039] Specifically, during cold pressing, the sheets are stacked on top of the pressing table 1, with the sheets placed in the center of the pressing table 1. Then, the first cylinder 4 is activated, driving the first telescopic rod 5 to extend, thereby moving the moving plate 6. One side of the positioning plate 9 is close to the side of the sheet, and the two sets of positioning plates 9 move towards the middle, thus pushing the two sides of the sheet to align. At this time, the second cylinder 7 is activated, driving the second telescopic rod 8 to retract, moving the positioning plate 9. The right angle of the positioning plate 9 pushes the other two sides of the sheet to align. The positioning plate 9 adjusts its position according to the length and width of the sheet, thereby aligning the four sides of the sheet. When the sheets are stacked high, the lifting frame 3 can be raised and lowered, driving the positioning plate 9 to rise, which has a wider range of applications. The neatly stacked sheets are conducive to the lower pressing table 10 pressing down, making the force more even and preventing misalignment.

[0040] Example 2:

[0041] Reference Figure 1-4The bracket 2 has a fixed plate 11 fixedly connected to its inner wall, a third cylinder 12 fixedly connected to the top of the fixed plate 11, a third telescopic rod 13 fixedly connected to the output end of the third cylinder 12, and a fixed connection between the bottom of the third telescopic rod 13 and the lifting frame 3. The lifting frame 3 has a buffer groove 14 on its inner wall and a slider 15 fixedly connected to its outer surface. One end of the first telescopic rod 5 is fixedly connected to a connecting plate 16, and one end of the moving plate 6 is fixedly connected to a mounting plate 17. The mounting plate 17 has a bolt 18 threadedly connected to its interior, and the connecting plate 16 has a threaded hole 19. The positioning plate 9 is L-shaped, and a reinforcing layer 20 is fixedly connected to its inner wall. There are four positioning plates 9, which are arranged in groups of two. The bracket 2 has a crossbeam 21 fixedly connected to its top. There are two brackets 2. The positioning plate 9 is made of metal, and the outer surface of the reinforcing layer 20 is coated with a wear-resistant coating 22.

[0042] Specifically, the fixed plate 11 supports the third cylinder 12, and there are two third cylinders 12 symmetrically distributed on both sides. The extension and retraction of the third telescopic rod 13 controls the lifting height of the lifting frame 3, making the lifting flexible. The buffer groove 14 facilitates the up and down sliding of the slider 15 and supports the lifting frame 3. The connecting plate 16 and the mounting plate 17 are the same in shape and size. During installation, the two are aligned. The bolts 18 pass through the threaded holes 19 for connection and installation. The reinforcing layer 20 can prevent the positioning plate 9 from easily deforming and keep its shape unchanged. The two sets of positioning plates 9 are symmetrically distributed, and the positioning effect is strong. The crossbeam 21 connects the two brackets 2 and reinforces the brackets 2. The wear-resistant coating 22 can prevent wear and ensure the flatness of the positioning surface.

[0043] In this invention, during cold pressing, the sheet metal is stacked on top of the pressing table 1, with the sheet metal placed at the center of the pressing table 1. Then, the first cylinder 4 is activated, driving the first telescopic rod 5 to extend, thereby moving the moving plate 6. One side of the positioning plate 9 approaches the side of the sheet metal, and the two sets of positioning plates 9 move towards the center, thus pushing the two sides of the sheet metal to align. At this time, the second cylinder 7 is activated, driving the second telescopic rod 8 to retract, moving the positioning plates 9. The right-angled angle of the positioning plates 9 pushes the other two sides of the sheet metal to align. The positioning plates 9 adjust their position according to the length and width of the sheet metal, thereby aligning the four sides of the sheet metal. With proper alignment, when the plates are stacked high, the lifting frame 3 can rise and fall, driving the positioning plate 9 to rise, thus expanding its application range. The neatly stacked plates facilitate the downward pressure of the lower press table 10, making the force more even and preventing misalignment. The extension and retraction of the third telescopic rod 13 controls the lifting height of the lifting frame 3, making the lifting flexible. The buffer groove 14 facilitates the up and down sliding of the slider 15, supporting the lifting frame 3. Bolts 18 pass through threaded holes 19 for connection and installation. The reinforcing layer 20 can prevent the positioning plate 9 from easily deforming, keeping its shape unchanged. The wear-resistant coating 22 can prevent wear and ensure the flatness of the positioning surface.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
