Description

Technical Field

[0001] The utility model relates to the technical field of pressing equipment, in particular to a pressing device for brazing aluminum honeycomb plates of special-shaped bus chassis. Background Art

[0002] The aluminum honeycomb panel is divided into three layers in its overall structure, namely the bottom plate, the honeycomb core and the cover plate. The contact surfaces of the bottom plate, the cover plate and the honeycomb core are connected by adhesive. Because of its excellent properties such as resistance to high wind pressure, shock absorption, sound insulation, heat preservation, flame retardancy and high specific strength, it is widely used in bus chassis and aviation equipment. For example, during the processing of special-shaped bus chassis aluminum honeycomb panels, they must be pressed before entering the brazing furnace for brazing to make the bottom plate, honeycomb core and cover plate tightly combined to avoid loosening and warping during subsequent brazing.

[0003] The clamping devices for brazing of aluminum honeycomb panels for special-shaped bus chassis that are commonly seen on the market are mostly similar in structure. They are mainly made of steel frames and use hydraulic cylinders as the main driving force to drive the clamping plates to move up and down, and press the bottom plate, honeycomb core, and cover plate blanks tightly. There are some functional deficiencies in actual use, and there is room for improvement. For example, during the pressing process, the horizontal state of the clamping plate has a decisive influence on the pressing effect of the honeycomb panel. Once the clamping plate is deflected, the surface of the honeycomb panel is unevenly stressed and it is easy to deform. The horizontal detection of the clamping plate is more troublesome and requires professional measuring tools for repeated measurement. It does not have the function of conveniently monitoring the horizontality of the clamping plate. Secondly, the thickness of the honeycomb panel itself is not large. In order to improve efficiency during pressing, multiple groups of honeycomb panels are generally stacked and pressed uniformly. After multiple groups of honeycomb panels are stacked, the mass is large. When unloading, they can only be unloaded manually one by one, and it is inconvenient to use tools such as forklifts. There are forklift grooves on the base of some models, which can easily cause groove-shaped indentations on the bottom honeycomb panel, and it does not have the function of lifting materials for easy removal.

[0004] Now, a novel clamping device for brazing special-shaped bus chassis aluminum honeycomb panels is proposed to solve the above problems. Utility Model Content

[0033] Working principle: When the utility model is used, first, the contact surfaces of the bottom plate, cover plate and honeycomb core of the special-shaped bus chassis aluminum honeycomb panel are evenly coated with adhesive, and then the honeycomb core is placed between the bottom plate and the cover plate. The bottom plate, cover plate and honeycomb core constitute a group of blanks. Multiple groups of blanks are neatly stacked above the bottom bearing seat 2. The hydraulic cylinder 13 drives the pressing plate 14 to press down so that the layers of the blanks below are tightly fitted. After the adhesive is completely solidified, it can be removed for subsequent brazing. The pressing plate 14 needs to be checked for horizontal state regularly. When checking, The material above the bottom bearing seat 2 is emptied, and the hydraulic cylinder 13 drives the pressing plate 14 to press down. The pressure rods 9 on both sides of the pressing plate 14 are pressed on the pressure plate 6 on the top of the pressure sensor 5. The pressure sensor 5 senses the pressure and feeds back on the LCD screen 4 on the surface of the support pier 3.

During the compression process of the honeycomb panel, the proximity sensor 24 in the shell 23 is turned on. When someone approaches the device, the first speaker 22 and the second speaker 25 synchronously play safety warning voices to remind relevant personnel to stay away from the device to avoid accidents causing personal injury.
