Embodiment Construction

[0024] Such as figure 1 As shown, the drawing die includes upper die 1, upper binder ring 2, lower binder ring 3, lower die 4, upper die 1, upper binder ring 2, lower binder ring 3, and lower die 4 from top to bottom Set in sequence. Both the upper binder ring 2 and the lower binder ring 3 can move up and down; the upper binder ring 2 and the lower binder ring 3 can be closed to form a bonding surface to clamp the plate. Such as figure 2 As shown, the upper mold is provided with a first concave small surface 5, a second concave small surface 6, a third concave small surface 7, and a fourth concave small surface 8, as Figure 5 As shown, the edge of the lower binder ring is provided with a first concave small surface 9, a second concave small surface 10, a third concave small surface 11, and a fourth concave small surface 12 that cooperate with the upper mold. Such as image 3 As shown, the edge of the upper blank holder is provided with an opening matching the aforementio...

Abstract

The invention relates to a stamping device and method for machining an inner plate of a covering part of an automobile. A drawing die comprises an upper die and a lower die and is further provided with an upper blank holder and a lower blank holder. The upper die, the upper blank holder, the lower die and the lower blank holder are successively arranged from top to bottom. The method comprises the steps of: during stamping, raising the lower blank holder, raising the upper die to an upper limit height, and raising the upper blank holder; putting a panel on the lower blank holder, wherein the upper blank holder moves downward till the upper blank holder and the lower blank holder are closed to form a binding face so as to clamp the panel; moving the upper die downward, wherein the upper die acts on a concave small profile at the edge of the lower blank holder for concave small profile forming on the panel; and continuously moving the upper die backward, wherein the upper die are integrated with the upper blank holder and the lower blank holder to be acted on the lower die so as to form the panel.

Description

technical field [0001] The invention relates to a stamping device and method for processing inner panels of automobile cover parts. Background technique [0002] During the stamping process of the inner panel of the automobile panel, the depth of the drawing die surface is relatively large, and the raw material consumption of the sheet is relatively large. The existing stamping devices are single-action drawing die structures, which cannot effectively solve the problem of a large amount of material loss. Contents of the invention [0003] The purpose of the present invention is to provide a stamping device and method for processing inner panels of automobile panels, which can effectively solve the problem of large material loss and effectively reduce material loss. [0004] Based on the same inventive concept, the present invention has two independent technical solutions: [0005] 1. A stamping device for processing inner panels of automobile panels. The drawing die incl...
