Abstract

The invention discloses a drawing die for plate forming. The drawing die comprises an upper die seat, a lower die seat and binders, wherein the binders comprise an upper die binder and an opposite lower die binder, an upper die elastic element is arranged between the upper die binder and the upper die seat, and a lower die pneumatic ejecting rod is arranged between the lower die binder and the lower die seat and is used for driving the lower die binder. The die has the advantages that the structure is compact, and the occupation space is little; the one-time forming is realized, meanwhile, the phenomenon of forming starting before material pressing is avoided, and the quality of the punched product is improved.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die used for plate forming. Background technique [0002] At present, under the requirements of consumers to pursue individualization, the shapes of automobiles are becoming more and more diverse. This has a series of problems such as the complexity of the shape of the panels and the large differences in shapes. It is difficult to form high-quality panels, especially for interior parts. The drawing depth of the plate is deeper, and it is accompanied by a plate with punch-drawn properties on the upper and lower sides. [0003] like Figure 4 As shown, the working principle of the traditional plate drawing die is as follows: Die opening stage: the upper die is lifted up, the lower die does not move, the air ejector rod pushes the blank holder upward for a stroke, and the blank is placed on the blank holder at this time ;Closing stage: the machine tool drives the upp...
