[0002] With the increasing demand for lightweight in industries such as new energy vehicles, aerospace, and 3C electronics, the stamping forming technology of aluminum alloy structural parts (such as battery trays, car doors, aircraft bulkheads, mobile phone middle frames, etc.) has become a research hotspot. However, the characteristics of aluminum alloy such as low ductility, high springback, and easy sticking to the die pose great challenges to traditional steel stamping dies: during the stamping process, lubricating oil needs to be applied to the die regularly to reduce wear, but existing technologies mostly use manual brushing or centralized lubrication systems, which cannot accurately lubricate the used die in real time. Manual lubrication has the risk of omission, while automatic lubrication systems often cannot distinguish the use state of the die, resulting in waste of oil. Summary of the Invention

[0003] The purpose of the present invention is to provide a stamping die for lightweight aluminum alloy structural parts with reasonable design and convenient use, which realizes double-sided alternating stamping and automatic lubrication through the coordinated cooperation of symmetrically rotating lower modules and atomizing lubrication mechanisms, improves the production efficiency by more than 30%, reduces the risk of aluminum alloy sticking to the die, and prolongs the service life of the die.

A rotating disk is arranged inside the bottom plate, and the two lower modules are arranged on the rotating disk; A rotating motor, which is embedded and fixed in the bottom plate, and the output shaft of the rotating motor is connected to a rotating rod through a worm and gear pair, and the rotating rod is arranged inside the bottom plate; A lifting mechanism, which is arranged inside the bottom plate, and the lifting mechanism is connected to the rotating disk and the rotating rod; An oil storage tank, which is arranged inside one side of the bottom plate, and a pumping and delivering pump is arranged inside the other side of the bottom plate. The inlet end of the pumping and delivering pump is connected to the oil storage tank through a pipeline; An atomizing mechanism, which is arranged at the rear side of the bottom plate, is arranged in cooperation with the lower module, and is connected to the outlet end of the pumping and delivering pump; Through the above technical solution, the aluminum alloy component is placed between the lower module and the upper module on the front side. The stamping machine drives the top plate and the upper module to move downward, so that the aluminum alloy component is formed. At this time, the upper module and the lower module are separated. Then, the lifting mechanism drives the rotating disk to move upward, and the rotating disk drives the two lower modules to move upward. The rotating motor is started, and the rotating motor drives the rotating rod to rotate through the worm and worm gear pair. The rotating rod drives the rotating disk to rotate through the lifting mechanism, and the rotating disk drives the two lower modules to rotate, so that the used lower module rotates to the rear side of the bottom plate, and the unused lower module rotates to the lower side of the upper module. At this time, the stamping operation is continued through the lower module and the upper module on the front side. Then, the pumping pump is started, and the pumping pump pumps the lubricating oil in the oil storage tank into the atomizing mechanism, so as to lubricate the lower module at the rear side.
