Stamping shaping die

Abstract

A stamping shaping die comprises an upper die and a lower die. The lower die comprises a male die core and a lower shaping insert, and a to-be-shaped workpiece can be placed on the male die core and the lower shaping insert. The upper die comprises an upper die base, the upper die base is provided with a middle material pressing core and two edge material pressing cores, the two edge material pressing cores are arranged in the width direction of the workpiece at intervals, the middle material pressing core is located between the two edge material pressing cores, and upper shaping inserts are arranged between the middle material pressing core and the two edge material pressing cores. The middle material pressing core and the edge material pressing cores are both in sliding connection with the upper die base in the vertical direction, elastic pieces are arranged between the middle material pressing core and the upper die base and between the edge material pressing cores and the upper die base, the middle material pressing core is used for being matched with the male die core so as to press the middle of the workpiece, and the edge material pressing cores are used for being matched with the lower shaping insert so as to press the edges of the workpiece. According to the stamping shaping die, material pressing constraints exist in the middle and the edges of the workpiece, material flowing is relatively stable in the shaping process, and part size adjustment is more efficient.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a stamping shaping die. Background technique [0002] Central channel stamping parts are important components of automobiles, which generally refer to components with a high raised part in the middle and an overall shape roughly in the shape of a "several". [0003] Please refer to Figure 1-Figure 3 , figure 1 It is a structural schematic diagram of a stamping and shaping die suitable for central channel stamping parts in the prior art, figure 2 It is the relative position diagram of the pressing core of the upper mold, the insert of the upper mold, the convex core of the lower mold, and the insert of the lower shaping before shaping. image 3 It is a state diagram when the upper mold insert just contacts the upper process part of the lower mold convex core. [0004] Such as figure 1 , figure 2 As shown, in the prior art, the stamping and shaping molds suitable for sta...

Problems solved by technology

[0006] However, if image 3 As shown, when the upper die insert 013 just contacts the process part, the lower part of the process part where the dotted circle originates (side part) in the figure is supported by the lower shaping insert 023, while the upper part is in an empty state, and there is no pressure constraint. In the next movement of the mold, the lower shaping insert 023 will shape the origin of the dotted line of the process part upwards. Since there is no pressure constraint at this position, the material flow at this position will be unstable, making subsequent part size adjustment more difficult.
