Embodiment Construction

[0008] Such as figure 1 Shown, the present invention comprises die body 8 and punch body 2, and punch body 2 comprises guide post 3, spring 4, punch fixed plate 5, punch seat 1, forming punch 6 and forming guide punch 7, The punch fixing plate 5 is connected with the punch seat 1 through the guide post 3 and the spring 4, the forming punch 6 is connected with the punch body 2 through the screw 9, and the forming guiding punch 7 is connected with the punch fixing plate 5 through the screw 10.

[0009] During the downward movement of the punch body 2, the forming punch 6 contacts the workpiece, the spring 4 is compressed, and the workpiece moves downward. The forming guide punch 7 acts as a blank holder in the vertical direction, giving the workpiece lateral pressure and effectively controlling the rebound of the workpiece. After the workpiece is formed, the punch body 2 goes up, and under the reaction force of the spring 4, the punch fixing plate 5 returns to its original posit...

Abstract

The invention provides a loader coaming profiling mold which has the advantages that a coaming is equally stressed in the shaping process, wrinkles and springback phenomena are eliminated and the profiling size meets design requirements. The profiling mold comprises a concave mold and a convex mold, wherein the convex mold comprises a shaping convex mold. The profiling mold is characterized in that the convex mold comprises a shaping guide convex mold; the convex mold comprises a convex mold fixing plate; the convex mold fixing plate is connected with a convex mold seat through a guide column and a spring; and the side edge of the shaping guide convex mold is designed to be matched with the shaping convex mold according to springback angles.

Description

technical field [0001] The invention relates to a forming die structure of loader fuselage parts, in particular to a loader coaming pressing die. Background technique [0002] The loader coaming is a thin plate part, and the workpiece is large and deep. When traditional processing is used, the coaming is easy to spring back and wrinkle during the forming process, resulting in dimensions that do not meet the design requirements and resulting in low production efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a loader coaming pressing die, which can make the coaming evenly stressed during the forming process, eliminate wrinkling and springback, and ensure that the pressing size meets the design requirements. [0004] The technical scheme adopted in the present invention is: it comprises a die body and a punch body, and the punch body includes a forming punch, and it is characterized in that: the punch body includes a...
