CN221952139U - A universal die for forming aircraft profiles with variable angles and sinking - Google Patents

Abstract

The utility model belongs to the technical field of aircraft profile forming dies, and specifically relates to a universal die for forming aircraft profiles with variable angles of depression. The traditional profile depression dies process the depression angles at fixed angles, and when different angles of depression are to be formed, different dies need to be replaced, which consumes a large amount of mold manufacturing and storage costs. The utility model proposes a universal die for forming aircraft profiles with variable angles of depression, including an upper die and a lower die, wherein the upper die includes an upper die seat and two upper stoppers, and the lower die includes a lower die seat, a lower stopper, a first forming block, a second forming block and other structures. By arranging a sliding structure under the second forming block, it is convenient to adjust the width of the depression forming; by arranging semicircular rotating blocks on the opposite sides of the first forming block and the second forming block, the angle of the forming depression can be adjusted; by replacing the second forming blocks of different heights, lower dies with different height differences can be assembled to form depressions of different heights, thereby saving the cost of making new molds.
