Description
Technical Field
The utility model belongs to the technical field of aerospace panel processing, and particularly relates to a bending forming device for an aerospace panel.
Background
The aerospace industry is very demanding in terms of materials, design and manufacturing as a peak combination of technology and engineering. The thin-wall plate is widely applied to high-end carrying equipment such as aerospace and meets the development requirements of lightweight, high performance, long service life and high reliability of aerospace equipment, and is generally manufactured by high-strength and difficult-to-form materials such as titanium alloy, aluminum alloy or composite metal. When the sheet is bent by using a traditional stamping forming process, a large amount of residual stress is formed, the metallographic structure of the sheet is damaged, and the reliability and durability of a finished product under extreme conditions are affected.
The laser bending forming process is a method of forming a sheet material, in which a laser beam is focused onto the surface of a workpiece by an optical system, and a localized area is heated, so that the material locally softens and changes its shape. However, since the laser beam energy is too concentrated, the sheet is usually bent with a small inner diameter, and a continuous arc segment cannot be produced, and there is a limitation in the shape of the sheet.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
Referring to fig. 1-2, in an embodiment of the present utility model, a bending device for a space board includes a processing table 1 and a thermoforming assembly 2, a clamping member 11 is disposed on the processing table 1, and an arc shaping table 12 is disposed at an edge of the processing table 1. The thermoforming assembly 2 comprises a plurality of laser heads 21 and a plurality of laser beam expanders 22, and the output direction of each laser head 21 is correspondingly provided with one laser beam expander 22.
The clamping piece 11 is used for fixing the plate on the processing table 1, one end of the plate is restrained by the clamping piece 11, and the other end of the plate is contacted with the shaping table 12 and extends out of the shaping table 12 for a certain distance. The shaping table 12 is entirely arc-shaped, and can define an arc in which the sheet material is to be bent. The laser beam expander 22 is used for expanding the laser released by the laser head 21, increasing the laser defocus amount and expanding the spot diameter. The laser heads 21 perform laser scanning on the section to be bent of the plate in time sequence, the thin plate bends through a bending mechanism, the laser scanning area of the plate is heated to gradually generate bending deformation, and finally large-inner-diameter bending is realized.
Example 1
Referring to fig. 1, a plurality of laser heads 21 are arranged along the arc direction of the shaping table 12. The laser irradiation route of the arrangement is simple, and the laser head 21 can be started gradually along the direction from the clamping piece 11 to the shaping table 12. However, the irradiation angle of the laser head 21 is not convenient to adjust due to the influence of the laser beam expander 22, and the arrangement position of the laser head 21 is not flexible enough.
Example 2
Referring to fig. 2, the apparatus further includes a plurality of reflecting plates 3, and each reflecting plate 3 is disposed corresponding to the output direction of each laser beam expander 22. After the laser beam released by the laser head 21 is expanded by the laser beam expander 22, the laser beam is reflected to the plate material by the reflecting plate 3. The laser irradiation route of the arrangement form is relatively complex, but the arrangement position of the laser head 21 is more flexible and changeable due to the fact that the reflecting plate 3 can change the irradiation direction of laser, and the arrangement can be adjusted according to actual conditions.
Further, the reflecting plate 3 is provided with an angle adjusting device 4 on a side different from the reflecting surface. The angle adjusting device 4 can adjust the angle of the reflecting plate 3 relative to the laser beam expander 22, and then adjust the reflection angle of the laser, so that the laser scanning area can be moved without adjusting the laser incidence position by moving the laser head 21.
The processing table 1 is further provided with a force application mechanism 13, the force application mechanism 13 being adapted to apply a certain pressure to the sheet material so that the sheet material can be formed along the shape of the shaping table 12. The force application mechanism 13 comprises an arc-shaped guide rail 131, a transmission rod 132 and a pull rod 133, wherein the pull rod 133 is in transmission connection with the arc-shaped guide rail 131 through the transmission rod 132. The arc-shaped guide rail 131 can drive the transmission rod 132 to move along the direction of the guide rail. One end of the pull rod 133 is connected with the transmission rod 132 in a hinged mode, and the other end of the pull rod 133 is abutted against the upper surface of the plate. When the transmission rod 132 moves, the pull rod 133 and the transmission rod 132 rotate relatively, and downward pressure is applied to the plate in the rotation process of the pull rod 133 to assist the bending formation of the plate.
Under the action of the buckling mechanism, the plate can be bent by itself through laser irradiation, so that the plate can be bent to a certain degree, and then the force application mechanism 13 is started to apply force to the plate, so that the force application form of the pull rod 133 is optimized.
In one embodiment, the apparatus further comprises a high pressure gas injector 5, the high pressure gas injector 5 being adapted to inject a high pressure gas stream towards the sheet material. For the thin-wall plate, the plate can be bent by applying an acting force through high-pressure airflow, and the stress of the plate is more uniform. The high-pressure air flow can be specifically nitrogen, and the high-pressure nitrogen can be sprayed to exert acting force and simultaneously form atmosphere protection on the plate, so that the performance of the heated area after forming is improved.
The foregoing is merely illustrative of the structures of this utility model and various modifications, additions and substitutions for those skilled in the art can be made to the described embodiments without departing from the scope of the utility model or from the scope of the utility model as defined in the accompanying claims.
