According to the forming die for the aviation perforated locating plate, which is shown in fig. 1, the forming die comprises a lower die plate 10, an upper die plate 20 and an extrusion bolt 30; the upper surface of the lower template 10 is provided with a molding step groove 11 and two connecting planes 15, the two connecting planes 15 are opposite along the width direction of the lower template 10, and the molding step groove 11 is a step structure penetrating along the length direction of the lower template 10; the molding step groove 11 is provided with a pressing position 12, a positioning table 13 and a plurality of positioning walls 14; two groups of first bolt holes 16 are correspondingly formed in the two connecting planes 15; the lower surface of the upper die plate 20 is provided with an extrusion boss 21, and a positioning plane 22 is formed in the area where the lower surface of the upper die plate 20 is adjacent to the extrusion boss 21; the shape of the lower surface of the extrusion boss 21 is matched with the shape of the extrusion position 12; two groups of second bolt holes 23 are correspondingly formed in the upper edge of the positioning plane 22 and opposite to the upper die plate 20; the two groups of extrusion bolts 30 are correspondingly arranged in the two groups of first bolt holes 16 and the two groups of second bolt holes 23 in a penetrating way; wherein, a rectangular sheet blank is placed on the extrusion position 12, and two ends of the sheet blank are respectively abutted with the positioning table 13 and the side walls of the plurality of positioning walls 14, which are adjacent to the extrusion position 12; the extrusion bolt 30 is used for extruding the upper die plate 20 towards the lower die plate 10 along the vertical direction, the positioning plane 22 is abutted with the connecting plane 15, the lower surface of the extrusion boss 21 is abutted with the extrusion position 12 to extrude and mould the rectangular sheet blank into an arc-shaped perforated positioning sheet, and the problem that a titanium alloy forming die in the prior art is difficult to process the perforated positioning sheet meeting the requirements is solved.
In particular, as shown in fig. 1, the structure of the extrusion position 12 is a concave arc structure; the lower surface structure of the extrusion boss 21 is a convex arch structure; when a metal piece with an arc or arch structure is processed, the metal piece is manually molded after being heated, the metal piece is difficult to operate, and standardized operation is difficult to achieve, but the arc of the extrusion position 12 of the die corresponds to the arch structure of the extrusion boss 21, and the metal piece can be extruded and molded into the corresponding arc by one-time extrusion, so that various problems in a common operation method are avoided.
In the implementation, as shown in fig. 1, the upper surface of the positioning table 13 is a sector; the positioning walls 14 are special-shaped mechanisms, when extrusion molding is performed, the lower surface of the extrusion boss 21 is abutted with the upper surface of the extrusion position 12, the positioning plane 22 is abutted with the connecting plane 15, the upper surfaces of the positioning table 13 and the positioning walls 14 are not abutted with the extrusion boss 21 and the positioning plane 22, a gap is reserved at the edge of the joint of the upper die plate 20 and the lower die plate 10, and the problem of blank deformation expansion in the extrusion process is prevented.
In practice, as shown in fig. 1, the positioning table 13 and the positioning wall 14 are each higher than the extrusion station 12, which prevents displacement of the sheet billet during extrusion, and keeps the sheet billet in the extrusion station 12.
