[0046] In this embodiment: the two side panels 1028 can be driven to dock through the adjustable support component 101, and the upper mold and the lower mold can be assembled on the mounting rail 1023, and then the pressure component 103 can cooperate with the hydraulic component 201 to realize alternating continuous stamping operations, and then the position of the pressure component 103 can be adjusted through the adjustment component 202, so that the dovetail seat 1032 enters the two dovetail guide rails 104, and the adjustable positioning component 203 removes the fixation of the hydraulic component 201, then the stamping of larger aviation sheet metal materials can be met, and different sizes of mounting plates 1021 can be assembled between the two side panels 1028, so that the stamping area can be expanded again, so that the device can quickly switch between different states, with low cost and higher applicability. Secondly, the device adopts a modular design, occupies a small space, and can be easily transported.

[0047] Working principle: During the stamping operation, the first screw 1013 is driven to rotate by turning the handle 1016, and the first screw 1013 is screwed into the threaded barrel 1012, so that the adjustment seat 1015 is close to the support seat 1011, and the two side plates 1028 move relative to each other and dock with each other, and then the aviation sheet metal material can be placed on the lower die. At this time, the electric hydraulic rod 1031 extends to drive the dovetail seat 1032 to move downward, and the dovetail seat 1032 can drive the side plate 1028 to move downward through the dovetail guide rail 104, so that the upper die moves downward to perform stamping operations on the aviation sheet metal material. During the stamping process, The side plate 1028 also drives the extension rod 2014 to move downward, so that the first piston 2012 moves downward, and the first piston 2012 introduces the liquid in the hydraulic cylinder 2011 on the other side through the first hose 2016. At this time, the first piston 2012 on the other side is controlled to move upward by hydraulic pressure, so that the side plate 1028 and the upper die on the other side can be lifted, and the aviation sheet metal material can be put in again. When the electric hydraulic rod 1031 retracts, the upper die is separated from the stamped aviation sheet metal material, and the upper die on the other side is stamped again by hydraulic pressure, so that the stamping operation is performed alternately;

[0048] When stamping a larger aviation sheet metal material, the handle 2022 is turned to drive the hollow screw 2021 to rotate, so that the hollow screw 2021 drives the threaded seat 2025 to translate, and the threaded seat 2025 can drive the electric hydraulic rod 1031 to move, and the electric hydraulic rod 1031 drives the dovetail seat 1032 to move, and the dovetail seat 1032 moves a distance and is located in the two dovetail guide rails 104. When the dovetail seat 1032 is away from the bracket 2037, the reset force of the third spring 2035 drives the bracket 2037 and the positioning rod 2036 to move, so that the positioning rod 2036 is separated from the positioning sleeve 2031 and the connecting port 2015, and at the same time, the second spring 2013 drives the second piston 2034 to reset upward, so that the extension rod 2014 is separated from the positioning sleeve 2031. At this time, the pressure component 103 can smoothly drive the two upper molds to perform stamping operations;

[0049] When stamping larger aviation sheet metal materials, the handle 1016 is used to drive the screw to rotate so that the screw is screwed out of the threaded barrel 1012. At this time, the two side panels 1028 are separated, and the mounting plate 1021 is assembled between the two side panels 1028. The first spring 1026 drives the latch 1024 to reset and snap into the sleeve 1029, thereby completing the connection between the mounting plate 1021 and the side panels 1028, and the corresponding upper and lower dies are assembled on the mounting rail 1023. Then, according to needs, the pressure component 103 can be adjusted to the middle through the adjustment component 202, and the stamping operation can be performed again.
