Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel processing technology, specifically to a pressing device for aluminum honeycomb panel processing. Background Technology

[0002] Hot pressing of aluminum honeycomb panels requires the use of adhesives to bond the aluminum honeycomb core to the aluminum alloy plate. Currently, during hot pressing, when the hot pressing head leaves the aluminum honeycomb panel, the upper aluminum alloy plate of the aluminum honeycomb panel will experience a slight rebound, resulting in insufficient bonding of the aluminum honeycomb panel. If hot pressing is carried out for a long time, and the hot pressing head is removed after the adhesive cools down, a large amount of hot pressing time is required, resulting in low processing efficiency.

[0003] A search of Chinese patent CN222351109U reveals a pressing device for processing aluminum honeycomb panels. The device pushes the pressed aluminum honeycomb panel into a conveyor belt, where two upper and lower conveyor rollers of fixed height transport the aluminum honeycomb panel while simultaneously pressing the aluminum honeycomb core and aluminum alloy plate together for a period of time. A fan is used to accelerate the curing time of the adhesive, thereby reducing the springback phenomenon of the aluminum honeycomb panel after pressing.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The cooling treatment of aluminum honeycomb panels produced by hot pressing is carried out by a fan set on the top of the conveying structure. However, the cooling is not uniform due to the unidirectional blowing. Some air force may be lost due to distance and angle issues, resulting in poor cooling effect. The discharge port of the lower mold is not blocked during hot pressing, and the aluminum honeycomb panels are prone to deformation when directly hot pressed, which reduces the processing efficiency of aluminum honeycomb panels.

[0007] The conveying mechanism is disposed on the outer wall of the mounting plate;

[0008] The conveying mechanism includes a conveying frame fixedly connected to the outer wall of the other side of the top of the mounting plate. The inner walls of the top and bottom of the conveying frame have several circular holes. Several conveying rollers are rotatably arranged on the inner walls of the circular holes. An air inlet is opened on one side of the outer wall of the conveying roller, and several air outlets are opened on the outer wall of the conveying roller. A fan is installed on one side of the outer wall of the conveying frame, and a fan is installed on the other side of the outer wall of the conveying frame. An air inlet pipe is fixedly connected to the top and bottom outer walls of the conveying frame. A connecting pipe is inserted into the output end of the fan and the fan, and the connecting pipe is connected to the air inlet pipe.

[0009] Preferably, the air outlets are arranged in a ring array, the lower pressure mold is slidably connected to the inner wall of the mounting groove, a baffle is fixedly connected to one side of the inner wall of the mounting groove, and a baffle is fixedly connected to the other side of the inner wall of the mounting groove.

[0013] This utility model provides an improved pressing device for processing aluminum honeycomb panels, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model is equipped with a lower pressing mold, a first baffle, a second baffle, a conveying roller, a conveying frame, and an air inlet pipe. The conveying roller is driven by an external drive motor and conveys the pressed aluminum honeycomb panel. Fans one and two blow air into the air inlet pipe, and the air enters the conveying roller and is then output through evenly distributed air outlets. While conveying the aluminum honeycomb panel, it can also provide uniform air cooling. The blowing air acts directly on the surface of the aluminum honeycomb panel, reducing air loss during the conveying process, resulting in uniform cooling and a good cooling effect. Furthermore, the discharge port of the lower pressing mold is blocked during hot pressing, making it less prone to deformation when the aluminum honeycomb panel is directly hot-pressed, thus improving the processing efficiency of the aluminum honeycomb panel.

[0015] Secondly, this utility model, by setting up conveyor rollers, air outlets and conveyor frames, can reduce the rebound phenomenon of aluminum honeycomb panels after hot pressing through timely and effective cooling. Direct and uniform cooling can significantly shorten the cooling time of aluminum honeycomb panels. Optimizing the blowing system can reduce the noise level and improve the practicality of the pressing device for processing aluminum honeycomb panels. Attached Figure Description

An air inlet pipe 7 is fixedly connected to the top and bottom outer walls of the conveying frame 4. Connecting pipes are inserted into the output ends of the fan 6 and the fan 12, and the connecting pipes are connected to the air inlet pipe 7.

[0028] Furthermore, the vent holes 13 are arranged in a ring array. The lower mold 3 is slidably connected to the inner wall of the mounting groove. A baffle 9 is fixedly connected to one side of the inner wall of the mounting groove, and a baffle 10 is fixedly connected to the other side of the inner wall of the mounting groove. Unloading holes 15 are opened on the outer walls of both sides of the bottom end of the lower mold 3. The dimensions of the unloading holes 15 are adapted to the dimensions of the baffle 9 and the baffle 10. The dimensions of the push plate 11 are adapted to the dimensions of the unloading holes 15. The unloading holes 15 on both sides of the bottom of the lower mold 3 are blocked by the baffle 9 and the baffle 10 in the mounting groove. The aluminum honeycomb panel is hot-pressed and formed. Then the upper mold and the lower mold 3 are separated. The electric push rod 8 pushes the lower mold 3 to rise and starts the cylinder 2. The push plate 11 passes through the unloading holes 15 to push the aluminum honeycomb panel to unload.

[0029] Furthermore, conveying holes 14 are provided on both outer walls of the conveying frame 4. The conveying holes 14 are adapted to the dimensions of the unloading hole 15 and the push plate 11.

[0030] Working principle: During the hot pressing process of aluminum honeycomb panels, the adhesive-coated aluminum alloy plate, aluminum honeycomb core, and aluminum alloy plate are placed sequentially in the lower mold 3. The upper mold hot presses the aluminum honeycomb panel. During the hot pressing process, the lower mold 3 is lowered into the mounting groove by the electric push rod 8. The unloading holes 15 on both sides of the bottom of the lower mold 3 are blocked by the baffle 9 and baffle 10 in the mounting groove.

Fans 1 and 2 blow air into the air inlet pipe 7. The air enters the sprockets and is then output through the evenly distributed air outlets 13. While conveying the aluminum honeycomb panels, the air can also be evenly cooled. The air blowers act directly on the surface of the aluminum honeycomb panels, reducing air loss during the conveying process. The even cooling can also reduce the thermal stress inside the aluminum honeycomb panels, preventing deformation or cracking.
