Two-way bending die

Abstract

The invention discloses a two-way bending die. The two-way bending die comprises an upper fixed plate, a lower fixed plate, an upper flexible plate, a lower flexible plate, a middle fixed plate, an upper support, a lower support, an upper punch, a lower punch, an upper driving device and a lower driving device; the upper fixed plate and the lower fixed plate are fixed on the upper side and the lower side of the middle fixed plate through the upper support and the lower support respectively; the upper flexible plate can vertically slide to be positioned below the upper fixed plate; the lower flexible plate can vertically slide to be positioned below the lower fixed plate; the upper punch is fixedly arranged on the lower side of the upper flexible plate; the lower punch is fixedly arranged on the upper side of the lower flexible plate; the middle fixed plate is provided with a product positioning device which is used for fixing and positioning a product to be bent; the lower end of the upper punch and the upper end of the lower punch face the surfaces of the upper side and the lower side of a bent position of the product to be bent respectively, wherein the product is arranged on the product positioning device; the upper driving device and the lower driving device are fixedly arranged on the upper fixed plate and the lower fixed plate respectively; the upper flexible plate and the lower flexible plate are driven by the upper driving device and the lower driving device to move respectively. According to the two-way bending die, the structure is simple and meanwhile the bending of double sides is achieved and accordingly the bending efficiency is high and the bending accuracy is high.

Description

technical field [0001] The invention relates to a metal mold, in particular to a bidirectional bending mold. Background technique [0002] Sheet metal products often have bending parts, especially some products need to be bent on both sides to form a structure that bends up and down, and even some bifurcated products need to bend both sides of the bifurcated parts to make them bend The bifurcated structure, the current bending of the next product is through multiple processes, one side is bent first, and then the other side is bent. In this way, the bending efficiency is low, time-consuming and labor-intensive, and the cost of the mold is high. And because the two sides are not bent at the same time, the rebound force and other effects after bending will lead to low precision and low yield of bent products, resulting in high processing costs. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a two-way bending die, wh...
