Description

Technical Field

[0001] The utility model relates to the technical field of structural component processing, in particular to a processing device for aviation precision structural components. Background Art

[0002] In the rapid development of the aviation industry, unprecedented high requirements have been placed on the processing accuracy, strength and reliability of aviation parts. With the advancement of technology, aviation parts continue to present more complex geometric shapes and require the use of advanced and special materials, which places extremely high demands on the precision of the processing technology. Under this development background, the processing of precision structural parts has become an important part of the aviation manufacturing process. Especially when processing metal precision structural parts, it is often necessary to use cold stamping technology to shape some materials, and the key to stamping technology is the use of high-precision stamping dies.

[0003] The patent with publication number CN213495867U discloses a stamping structure for precision metal structural parts, including a pressing module and a die seat, the positions of the pressing module and the die seat correspond vertically, a mounting base is fixedly installed at the bottom end of the die seat, a mounting top plate is fixedly installed at the top of the pressing module, a lifting drive is fixedly installed at the middle of the top of the mounting top plate, and clamping pieces are fixedly connected on both sides of the top of the mounting base. The utility model realizes clamping of both ends of the stamping material by arranging clamping pieces with a symmetrical structure at the top of the mounting base, thereby improving the stability of the metal structural parts during processing, and further improving the precision of the metal structural parts; by arranging mutually connected nozzles and air guide cylinders in the pressing module, and using a high-pressure air intake machine connected to the air intake pipe seat in combination, the inner wall of the stamping groove of the die seat is effectively cleaned, thereby improving the cleaning effect of the inner wall of the die seat, and further effectively improving the processing efficiency of the metal structural parts.

[0004] The above-mentioned prior art has limitations in the specific use process. Nozzles are fixedly inserted on both sides of the pressing module for cleaning operations. Such a design may cause the surface of the metal structure to be pressed out of the nozzle opening when cooperating with the die seat to stamp metal structural parts, which affects the stamping quality of the metal structural parts. This problem highlights that while the prior art improves processing quality and efficiency, it also needs to continue to solve new problems to meet the more stringent quality requirements in the aviation field. In view of this, we propose a processing device for aviation precision structural parts. Utility Model Content
