The invention discloses a punch vacuum loading tooling, which comprises a punch, a positioning block and a baffle; The convex platform around the convex model panel and the bottom extension plate; the positioning block is arranged between the two ends of the wall plate to be loaded along the length direction and the convex platform; the two ends of the baffle plate are respectively detachable. On the surface, the middle part is above the wall plate to be loaded; the two baffle plates are symmetrically distributed along the centerline of the width direction of the convex model panel. The invention also discloses a manufacturing and forming method of the outer grid wall plate, which adopts the aforementioned punch vacuum loading tooling. The vacuum loading tooling for a punch of the present invention has a simple structure and is convenient to install, and can effectively ensure the forming accuracy of the ribs and grids in the vacuum creep aging forming of the outer grid wall plate.
Description
technical field [0001] The invention belongs to the technical field of creep aging forming, and in particular relates to a method for manufacturing and forming a punch vacuum loading tooling and an outer grid wall plate. Background technique [0002] Creep aging forming is a new type of sheet metal forming technology, which can realize forming and strength improvement of components at the same time, and is widely used in the manufacture of large thin-walled components in aerospace. The creep aging forming process can be divided into three stages: loading stage, creep aging stage, and unloading stage. Among them, the bending loading methods of components mainly include mechanical loading and vacuum bag loading. The mechanical loading method requires two sets of concave and convex molds, but there are problems such as long heating time and large space volume, and is generally only suitable for small-scale components in the laboratory; the vacuum bag loading method is suitable ...
