Description

Technical Field

[0001] This utility model relates to the technical field of honeycomb panel production equipment, and more specifically, it relates to a hot pressing device for the production of aluminum honeycomb panels. Background Technology

[0002] Honeycomb panels are widely used in building decoration, furniture manufacturing, transportation and other fields due to their excellent properties such as light weight, high strength, sound insulation and heat insulation. One of the core processes in their production is to use a hot press to bond the upper and lower panels and the honeycomb core material together under the action of heat and pressure. In existing honeycomb panel production technologies, hot pressing devices typically consist of a frame, upper and lower hot pressing plates, and a hydraulic drive system. However, these devices have revealed several problems in practical use. First, the large-area, integral hot pressing plates make it difficult to ensure uniform pressure and temperature on the panel surface, easily leading to localized delamination, bubbling, or poor adhesion in the honeycomb panels. Second, the equipment has limited functionality; feeding, positioning, and discharging largely rely on manual labor or additional equipment, resulting in low automation and impacting production efficiency and product consistency. Third, the hot pressing plates and drive components are mostly rigidly connected, making it difficult to adapt to the microscopic unevenness of the panel blank, potentially causing crushing or insufficient pressure. Finally, the traditional series-connected heating channel design causes a significant temperature drop in the heat transfer medium during flow, further exacerbating the unevenness of the temperature field. Therefore, based on the problems existing in the prior art, a hot pressing device that can achieve uniform heating and pressurization, automated continuous production, and strong adaptability is provided. Utility Model Content

[0006] Optionally, the upper hot press plate is composed of several independent hot press unit modules arranged in a matrix; the hot press unit module is provided with a ball head connector, and the ball head connector is detachably connected to the output end of the hydraulic drive component; Each of the hot pressing unit modules is provided with a flexible metal pipe, and the flexible metal pipes are connected in parallel to form a heating flow channel in the upper hot pressing plate.

[0007] Optionally, the heat medium supply module includes: a heat medium storage cylinder for storing heat medium and a heat medium distributor for distributing the stored heat medium; The output end of the heat medium storage cylinder is connected to the input end of the heat medium distributor; the output end of the heat medium distributor is connected to the heating channel of the upper hot plate and the heating channel of the lower hot plate, respectively.

[0008] Optionally, the lower hot press plate is an integrally formed structure; the lower hot press plate has several parallel heating pipes inside, and the input and output ends of the several heating pipes are connected through a manifold to form a zigzag flow path.

[0009] Optionally, the first guide module includes: two guide units, an upper guide plate, and a lower guide plate; The two guide units are symmetrically and detachably disposed on the machine body; the two guide units are spaced a first distance apart to form a first guide zone for guiding the sheet material to be hot-pressed into the machine body; The upper guide plate and the lower guide plate are symmetrically and detachably mounted on the machine body; the upper guide plate and the lower guide plate are separated by a second distance to form a second guide area for guiding the sheet material to be hot-pressed into the processing area; the second guide area is connected to the input end of the processing area; the second distance is slightly greater than the first distance.

[0010] Optionally, the second guiding module includes: a first guiding roller and a second guiding roller; the first guiding roller and the second guiding roller are respectively symmetrically and detachably disposed on the machine body; the first guiding roller and the second guiding roller are separated by a third distance to form a third guiding area for guiding the hot-pressed honeycomb panel out of the machine; the third guiding area is connected to the output end of the processing area.

[0014] In summary, this utility model has the following beneficial effects: 1. Traditional equipment with an integral upper pressure plate, due to its rigid connection, cannot handle the microscopic unevenness or slight warping of the slab blank. This utility model discretely sets the upper pressure plate into multiple independently driven hot pressing unit modules. Each module is flexibly connected to an independent hydraulic cylinder through a ball joint connector. This allows each module to adjust according to a programmed setting when contacting the slab blank, thereby performing slight angle deflection and independent stroke compensation, automatically conforming to the surface contour of the slab blank, and realizing conformal pressing. This structure largely eliminates the phenomenon of excessive local pressure caused by uneven slab blank, which may crush the core material, or insufficient pressure leading to weak adhesion, ensuring a high degree of consistency in the bonding strength of the entire honeycomb panel surface, and effectively solving quality defects such as bubbling and delamination during honeycomb panel molding.

[0015] 2. This utility model further improves the heat medium flow channels of the upper and lower hot press plates. For the upper hot press plate, each hot press unit module is connected in parallel to the heat medium distributor through flexible metal pipes, ensuring that the inlet heat medium temperature of all hot press unit modules is instantaneously consistent, avoiding the temperature difference on the plate surface caused by the temperature drop of the heat medium in the series flow channel. For the lower hot press plate, the zigzag heating flow channel set inside extends the flow of the heat medium, allowing heat to be transferred more fully and evenly to all parts of the lower hot press plate, reducing the temperature difference between the edge and the center. The uniformity of the overall temperature field allows the adhesive to reach the optimal curing state simultaneously on the entire plate surface, further ensuring the bonding quality, while reducing energy waste caused by local overheating or insufficient heating.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This utility model provides a hot pressing device for the production of aluminum honeycomb panels, such as... Figure 1 As shown, the device includes a body; the body is provided with: a first guide module for feeding and guiding the sheet material to be hot-pressed, a hot pressing module for hot-pressing the sheet material input by the first guide module to form a honeycomb panel, a hot media supply module for providing heat medium to the hot pressing module, and a second guide module for outputting and guiding the formed honeycomb panel.

[0023] Specifically, the machine body is a rigid frame structure welded from structural steel. At the feed end of this frame, a first guide module is fixedly installed by bolts to receive and guide the pre-bonded, hot-pressed raw material of the sheet material sent from the upstream conveyor line. In the middle of the machine body, the hot-pressing module is installed to perform the hot-pressing function. The heat medium supply module, as an independent unit, is placed on the side of the machine body by a bracket and is connected to the inlet and outlet of the hot-pressing module through a high-temperature metal pipeline to form a closed loop. At the discharge end of the machine body, a second guide module is installed through a bearing seat to receive and guide the cured honeycomb panel into the subsequent processing station.

[0024] Furthermore, the hot pressing module includes: an upper hot pressing plate, a lower hot pressing plate, and a hydraulic drive component for driving the upper hot pressing plate to rise and fall; both the upper and lower hot pressing plates are provided with heating channels; the heating channels are connected to the heat medium supply module; The upper and lower hot press plates are detachably connected to the machine body and are symmetrically arranged to form a processing area for placing the sheet material to be hot-pressed; the hydraulic drive component is detachably connected to the machine body, and the output end of the hydraulic drive component is detachably connected to the upper hot press plate; the upper and lower hot press plates cooperate to hot-press the sheet material in the processing area into a honeycomb panel.

[0025] Furthermore, the upper hot press plate is composed of several independent hot press unit modules arranged in a matrix; the hot press unit module is provided with a ball head connector, and the ball head connector is detachably connected to the output end of the hydraulic drive component; Each of the hot pressing unit modules is provided with a flexible metal pipe, and the flexible metal pipes are connected in parallel to form a heating flow channel in the upper hot pressing plate.

[0026] Specifically, the upper hot press plate consists of several independent hot press unit modules, which are made of alloy steel modules. In the preferred embodiment, the upper hot press plate is composed of 16 independent alloy steel modules. A ball socket, i.e., a ball head connector, is welded to the center of the back of each unit module. Each module has an independent U-shaped heating flow channel inside. The inlet and outlet of the flow channels of all modules are connected to a common inlet and outlet main pipe through flexible metal pipes, preferably stainless steel corrugated pipes. In the specific working process, when the hydraulic drive pushes all modules downward, each module gains a certain degree of freedom through the ball joint connector. At the moment of contact with the slab, each module can independently perform a small angle deflection and stroke compensation according to the set hot pressing program and the surface contour of the slab, ensuring that the bottom surface of all modules effectively contacts the slab at the same time and achieving uniform pressure. During the heating process, the high-temperature heat medium flows out from the heat medium distributor and enters the heating channel of each module simultaneously and isothermally through the parallel flexible metal pipeline, solving the temperature drop problem of the series method and ensuring the temperature uniformity of the entire upper pressure plate plane.

[0027] Furthermore, the heat medium supply module includes: a heat medium storage cylinder for storing heat medium and a heat medium distributor for distributing the stored heat medium; The output end of the heat medium storage cylinder is connected to the input end of the heat medium distributor; the output end of the heat medium distributor is connected to the heating channel of the upper hot plate and the heating channel of the lower hot plate, respectively.

[0028] Specifically, the heat medium storage tank is a thermal oil furnace equipped with a heater, circulating pump, and control system; the heat medium distributor is a multi-outlet insulated valve block; the outlet of the storage tank is connected to the main inlet of the distributor. One outlet of the distributor is connected to the lower hot press plate, and the other set of outlets is connected to each hot press unit module of the hot press plate through valves and pipelines; In the specific implementation process, the circulating pump pumps the heat medium from the heat medium storage cylinder and sends it to the heat medium distributor. The distributor synchronously splits the heat medium into two paths: one path directly enters the zigzag flow path of the lower hot press plate; the other path enters all the hot pressing unit modules of the upper hot press plate through multiple parallel branches and flexible metal pipelines. After completing the heat exchange, the two heat mediums flow back to the storage cylinder for reheating, forming two independent and synchronous circulation loops to ensure the temperature balance of the upper and lower hot press plates and further guarantee the effect of hot pressing.

[0029] Furthermore, the lower hot press plate is an integrally formed structure; the interior of the lower hot press plate has several parallel heating pipes, and the input and output ends of the several heating pipes are connected through a manifold to form a zigzag flow path.

[0030] Specifically, the lower hot press plate is machined from an integral forging, with several parallel drilled heating pipes inside, and longitudinal manifolds connected to all the parallel pipes are machined at both ends of the plate. In the specific implementation process, the heat medium from the heat medium distributor enters from the inlet of one end of the manifold, flows alternately through each parallel heating pipe, and finally flows out from the outlet of the other end of the manifold. This zigzag flow path allows the heat medium to traverse the entire plate area, greatly increasing the flow rate and heat exchange time, thereby improving the uniformity of the temperature field of the lower hot plate itself.

[0031] Furthermore, the first guide module includes: two guide units, an upper guide plate, and a lower guide plate; The two guide units are symmetrically and detachably disposed on the machine body; the two guide units are spaced a first distance apart to form a first guide zone for guiding the sheet material to be hot-pressed into the machine body; The upper guide plate and the lower guide plate are symmetrically and detachably mounted on the machine body; the upper guide plate and the lower guide plate are separated by a second distance to form a second guide area for guiding the sheet material to be hot-pressed into the processing area; the second guide area is connected to the input end of the processing area; the second distance is slightly greater than the first distance.

[0032] Specifically, two guide units are bolted to both sides of the machine body inlet, with a spacing slightly wider than the slab. The typical value of the first distance is 8mm thicker than the slab, thus forming the first guide zone. The upper guide plate and the lower guide plate are fixed to the hot press module inlet, with a gap slightly wider than the first guide zone. The typical value of the second distance is 3mm thicker than the slab, slightly thicker than the slab. In the specific implementation process, the first guide zone plays a coarse positioning role. Through the guidance effect of the two guide units, it constrains and coarsely centers the width direction, corrects large positional deviations, and allows it to enter the machine body better. At the same time, if the blank has head warping, it can be corrected here to ensure that it enters the machine body straight and smoothly. The second positioning zone plays a fine positioning role, ensuring that it enters the subsequent processing area directly in the horizontal direction and enters the processing area in a straight posture and smoothly.

[0033] Furthermore, the second guiding module includes: a first guiding roller and a second guiding roller; the first guiding roller and the second guiding roller are respectively symmetrically and detachably disposed on the machine body; the first guiding roller and the second guiding roller are separated by a third distance to form a third guiding area for guiding the hot-pressed honeycomb panel out of the machine; the third guiding area is connected to the output end of the processing area.

[0034] Specifically, the first and second guide rollers are chrome-plated steel rollers, which are installed on both sides of the machine outlet via bearings with seats; the distance between the two rollers is set to form a third guide zone, which is thicker than the finished plate. The typical value of the third distance is 1-2 mm thicker than the finished honeycomb plate. In the specific implementation process, after the honeycomb panel is hot-pressed and formed, it is sent out from the open processing area and then enters the third guide area. During the output of the honeycomb panel, the two guide rollers provide only slight positive limit to prevent deviation and ensure that the surface of the finished panel is not scratched with extremely low rolling friction, so as to achieve smooth material discharge.

[0035] Furthermore, the guiding unit includes: an installation roller and a guide wheel; the installation roller is detachably connected to the machine body; the guide wheel is detachably connected to the installation roller.

[0036] Specifically, the mounting roller is a smooth shaft, with both ends fixed to the machine body by UCF bearings with seats; the guide wheel is a POM plastic pulley with a bearing in the center, the inner hole of the bearing is fitted onto the mounting roller, and its axial movement is restricted by a shaft retaining spring. In the specific implementation process, when the side of the sheet material comes into contact with the guide unit, it comes into contact with the freely rotating guide wheel; the guide wheel rotates under the friction of the sheet, turning sliding friction into rolling friction, thereby greatly reducing the feeding resistance, avoiding wear on the edge of the sheet, and ensuring a smooth and unobstructed feeding process.

[0037] Furthermore, a temperature sensor may be provided on the surface of the upper hot press plate that is in contact with the raw material of the sheet to be hot-pressed.

[0038] Furthermore, the hydraulic drive component includes a plurality of hydraulic cylinders corresponding one-to-one with the plurality of hot pressing unit modules; the piston rods of the hydraulic cylinders are detachably connected to the ball joint connectors on the corresponding hot pressing unit modules.

[0039] Specifically, the hydraulic drive unit includes several corresponding independent small hydraulic cylinders. The cylinder bodies are fixed to the top mounting plate of the machine body in a matrix corresponding to the hot pressing unit modules. The end of each piston rod is machined into a ball head, which is embedded in the ball socket on the back of the corresponding module and is axially limited by a snap ring, thereby providing an independent power source for each hot pressing unit module (311). When the mold is closed, all hydraulic cylinders move synchronously. Since the independent drive is equipped with ball joints, the force applied by each module is relatively independent, which can realize the adaptive pressurization function in the program.

[0040] Optionally, at least one layer of elastic heat-conducting pad is provided on the top of the lower hot press plate at the bottom of the upper hot press plate.

[0041] Specifically, the elastic thermal pad is a 2mm thick high-temperature silicone rubber sheet, which is fully adhered to the bottom surface of all upper hot-pressing unit modules and the top surface of the lower hot-pressing plate using high-temperature resistant silicone adhesive. During mold closing and pressurization, the elastic pad undergoes slight deformation, which can absorb local impact stress and further compensate for microscopic unevenness, making the pressure distribution more gentle and uniform. At the same time, it fills the microscopic gaps between the hot-pressing plate and the blank, reduces contact thermal resistance, improves heat conduction efficiency, and further protects the surface of the honeycomb panel, preventing the hard metal hot-pressing plate from directly contacting and damaging the surface of the panel.

[0042] The programming involved in the above embodiments is implemented by the PLC program built into the machine, which is one of the technologies commonly used by those skilled in the art. In a more preferred embodiment, a more powerful MCU and microcontroller can be installed to further achieve better processing results.

[0043] This invention relates to a hot-pressing device for aluminum honeycomb panel production. Traditional equipment uses a rigid, integral upper pressure plate, which cannot handle microscopic unevenness or slight warping of the slab. This invention discretely sets the upper pressure plate into multiple independently driven hot-pressing unit modules. Each module is flexibly connected to an independent hydraulic cylinder via a ball-head connector. This allows each module to adjust according to a programmed setting when contacting the slab, enabling minute angular deflections and independent stroke compensation, automatically conforming to the slab surface contour and achieving conformal pressing. This structure largely eliminates the possibility of excessive local pressure due to slab unevenness, which could crush the core material, or insufficient pressure leading to weak adhesion, ensuring a high degree of consistency in the bonding strength of the entire honeycomb panel surface and effectively solving the honeycomb panel production problem. This invention addresses quality defects such as bubbling and delamination during the molding of heat exchange plates. It further improves the heat medium flow channels of the upper and lower heat exchange plates. For the upper heat exchange plate, each heat exchange unit module is connected in parallel to the heat medium distributor via flexible metal pipes, ensuring that the inlet heat medium temperature of all heat exchange unit modules is instantaneously consistent, avoiding temperature differences on the plate surface caused by heat medium temperature drop in the series flow channels. For the lower heat exchange plate, the zigzag heating flow channel inside extends the heat medium flow, allowing heat to be transferred more fully and evenly to all parts of the lower heat exchange plate, reducing the temperature difference between the edge and the center. This uniformity of the overall temperature field allows the adhesive to reach its optimal curing state simultaneously across the entire plate surface, further ensuring bonding quality and reducing energy waste caused by localized overheating or underheating.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
