Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of honeycomb panel production equipment, and more specifically, it relates to a segmented honeycomb panel cold press. Background Technology
[0002] Current cold presses for honeycomb panels mainly adopt an integral pressing plate structure. Although the structure is simple, it cannot adapt to local deformation differences in the panels, resulting in uneven pressure distribution. Specifically, existing technologies have the following core problems: 1. Molding defects caused by uneven pressure: When applying pressure with a monolithic press, the pressure cannot be adjusted according to the warping or thickness variations in different areas of the panel. Large-size honeycomb panels are prone to localized deformation (such as edge collapse or center depression) due to material properties. Uneven pressure distribution from traditional equipment results in weak adhesion, uneven surfaces, and a finished product qualification rate of less than 70%. This not only increases the scrap rate but also reduces production efficiency.
[0003] Second, poor equipment adaptability and high modification costs: Existing pressure plates are mostly fixed structures, which cannot be quickly adjusted in size or replaced with components to adapt to the production of honeycomb panels of different specifications (such as changes in thickness or size). When production needs change, the entire pressure plate needs to be disassembled or a new pressure plate needs to be customized, resulting in high modification costs (usually accounting for more than 30% of the total equipment cost) and long downtime, affecting the flexibility of the production line.
[0004] 3. Low conveying and positioning efficiency: The conveying system of the cold press relies heavily on manual handling or fixed rollers, making precise positioning difficult. The process of moving the sheet material in and out is time-consuming, and manual operation can easily lead to misalignment. The connection with the pressing station is not tight, extending the processing time by about 40% per cycle and hindering continuous production.
[0005] Therefore, this utility model provides a segmented honeycomb panel cold press. (Invention Content) Utility Model Content

Figures 1 to 6 As shown, it includes a main steel beam frame 100 and a segmented pressure plate device 200, wherein the segmented pressure plate device 200 is disposed on the main steel beam frame 100. The main steel beam frame 100 is a rectangular three-dimensional frame composed of several steel beams. The main steel beam frame 100 includes an upper frame 110, a lower frame 120 and a side frame 130. The upper frame 110 and the lower frame 120 are connected by the side frame 130. The bottom of the side frame 130 is provided with an inclined support foot 140, and the bottom of the lower frame 120 is provided with a rib support 150. The segmented pressure plate device 200 includes at least two sets of independent pressure plate units 300 spaced apart along the length of the main steel beam frame 100. In this embodiment, the segmented pressure plate device 200 is provided with three sets of independent pressure plate units 300 spaced apart along the length of the main steel beam frame 100. Figure 1 As shown, each group of independent pressure plate units 300 includes an upper pressure assembly 310, a lower support mechanism 340, a hydraulic drive mechanism 350, a vertical guide mechanism 360, and a side conveying assembly 370. The upper pressure component 310 is horizontally arranged on the upper part of the main steel beam frame 100; The lower support mechanism 340 is horizontally positioned at the bottom of the main steel beam frame 100, directly opposite the upper pressure assembly 310. The hydraulic drive mechanism 350 is fixed to the top of the main steel beam frame 100, and the hydraulic drive mechanism 350 is connected to the upper pressure assembly 310. The vertical guide mechanism 360 includes a pair of guide columns 361 and a guide kit 362. The pair of guide columns 361 are respectively disposed on the inner sides of the main steel beam frame 100. The upper and lower ends of the guide columns 361 are fixedly connected to the main steel beam frame 100. The guide kit 362 is slidably sleeved on the guide columns 361 and is connected to the upper pressure assembly 310. The side conveying assembly 370 is disposed on both sides of the lower support mechanism 340.
[0025] It should be noted that: by setting at least two sets of independent pressure plate units 300 arranged at intervals along the length direction, this utility model can implement differentiated pressure control on different areas of the honeycomb panel, avoiding the uneven pressure distribution caused by the warping of the panel in traditional integral pressure plates, and significantly improving the forming qualification rate of large-size honeycomb panels; in addition, the main steel beam frame 100 adopts a combination of inclined support feet 140 and rib supports 150. The inclined support feet 140 enhance lateral stability, and the rib supports 150 strengthen the compressive strength of the lower frame 120, jointly solving the problem of frame deformation during cold pressing and extending the service life of the equipment; furthermore, the vertical guide mechanism 360 and the side conveying component 370 are integrated into the same pressure plate unit to realize the integrated operation of panel positioning, pressing and removal, reducing process changeover time.
[0026] The upper pressing assembly 310 includes an upper pressing connection mechanism 320 and an upper pressing unit 330. The upper pressing connection mechanism 320 is connected to the hydraulic drive mechanism 350 and the guide kit 362. The upper pressing connection mechanism 320 includes an upper connecting plate 321, a C-shaped steel plate 322, and a lower connecting plate 323. The upper side of the C-shaped steel plate 322 is connected to the upper connecting plate 321, and the lower side of the C-shaped steel plate 322 is connected to the lower connecting plate 323. The upper pressing unit 330 and the lower connecting plate 323 are fixedly connected by bolts and nuts. In the combined design of the upper connecting plate 321, C-shaped steel plate 322, and lower connecting plate 323 of the upper pressing connection mechanism 320, the C-shaped steel plate 322 absorbs hydraulic impact vibration, and the upper and lower connecting plates 323 disperse pressure, reducing the risk of deformation of the upper pressing assembly 310 and ensuring the flatness of the pressing surface.
[0027] The aforementioned upper pressing units 330 are all modular assembly structures. Each upper pressing unit 330 includes several upper pressing assembly plates 331, an upper pad plate 332, and several upper side stiffeners 333. The upper pressing units 330 are assembled into upper pressing blocks by several upper pressing assembly plates 331. The upper pressing units 330 form modular pressing blocks by bolt-connected upper pressing assembly plates 331. With the detachable upper pad plate 332, the width and length of the pressing plate can be flexibly adjusted to adapt to the production of honeycomb panels of different specifications, resulting in low modification costs. The upper pressing units 330 are connected to the lower connecting plate 323 of the upper pressing connection mechanism 320 through the upper pad plate 332. Several upper side stiffeners 333 are evenly spaced on both sides of the upper pressing block. The evenly spaced upper side stiffeners 333 on both sides of the upper pressing block form a mesh support structure, which suppresses bending deformation in the middle of the pressing plate and ensures uniform pressure distribution when ultra-wide plates are pressed.
[0028] The lower support mechanism 340 includes a lower pad plate 341, a lower fixing plate 342, a lower support square tube 343, and lower side stiffeners 344.

The lower fixing plate 342 is disposed on the lower pad plate 341, and the lower support square tube 343 is fixedly connected to the center of the lower fixing plate 342. In the hierarchical design of the lower pad plate 341, the lower fixing plate 342, and the lower support square tube 343 of the lower support mechanism 340, the lower pad plate 341 absorbs the deformation stress of the frame, the lower support square tube 343 provides rigid support to avoid pressure damage to the honeycomb core layer, and several lower side stiffeners 344 are evenly arranged on both sides of the lower support square tube 343. The evenly spaced lower side stiffeners 344 on both sides of the lower support square tube 343 convert concentrated loads into distributed loads to prevent the thin-walled square tube from being crushed and deformed.
[0029] The hydraulic drive mechanism 350 includes hydraulic cylinders 351 symmetrically arranged on the top of the main steel beam frame 100. The piston rod of the hydraulic cylinder 351 is connected to the upper pressing assembly 310. The hydraulic cylinders 351 are mounted and fixed on the upper frame 110 of the main steel beam frame 100 via a fixing bracket 352. A limit rod 353 is provided on the fixing bracket 352. The symmetrically arranged hydraulic cylinders 351, in conjunction with the limit rod 353 on the fixing bracket 352, forcibly constrain the horizontal movement of the upper pressing assembly 310, avoiding the problem of uneven load caused by asynchronous multi-cylinder drive. The limit rod 353 is connected to the upper pressing assembly 310. The hydraulic drive mechanism 350 can independently adjust the pressure parameters to perform customized cold pressing molding of honeycomb panels of various specifications and types, thereby improving the cold pressing molding quality of the honeycomb panels.

The piston rod of the lifting cylinder 376 is connected to the roller connecting frame 374. Guide rod seats 377 are symmetrically arranged on both sides of the lifting cylinder 376. The guide rod 378 is sleeved inside the guide rod seat 377. The guide rod seat 377 is fixedly connected to the roller connecting frame 374. One end of the guide rod 378 is connected to the roller connecting frame 374, and the other end of the guide rod 378 is connected to the rib support 150.
