A precision progressive die for multi-bending forming

Abstract

The invention discloses a precision progressive die with a multi-bending forming function. The precision progressive die comprises a base (1), a lower cushion plate (2), an upper cushion plate (3) and a female die body (4), wherein the lower cushion plate (2), the upper cushion plate (3) and the female die body (4) are arranged on the base (1) and sequentially connected from bottom to top. An upper support (5) is arranged above the female die body (4) and internally provided with a female die insert A (6) and a female die insert B (7). The lower end of the female die insert A (6) is connected with a pressing die body (8), and an ejector rod (11) located under the pressing die (8) is arranged in a square cavity (9). The lower end of the female die insert B (7) is connected with a wedge B (14), a circular bead is arranged on the left side of the wedge B (14), and the wedge B (14) is located over a cavity (10). An arc chamfer matched with the circular bead is arranged on the left side wall of the cavity (10). The precision progressive die has the beneficial effects that the structure is compact, the bending angle is precise, continuous bending is achieved, bending efficiency is improved, and the production output is increased.

Description

Technical field [0001] The invention relates to the technical field of sheet metal bending, in particular to a precision progressive die for multiple bending forming. Background technique [0002] In the electronics production industry, sheets of various shapes are usually produced by bending, among which the most commonly used sheets are figure 2 As shown, the sheet material is composed of a vertical portion 15, a horizontal portion 16 and a bending portion 17 connected in sequence. The horizontal portion 16 is connected to the upper end of the vertical portion 15, and the bending portion 17 is connected to the right end of the horizontal portion 16. The existing bending method is to first bend the head of the vertical plate to the right to form the horizontal part 16, and then press the die to the right end of the horizontal part 16 to form the bent part 17. However, each station needs to be renewed. Positioning, there is processing discontinuity, each station needs to be repos...
