A kind of die structure of oblique wedge flanging of automobile front cover outer panel

Abstract

The present invention relates to an inclined-wedge die structure of an outer panel of an automotive front cover; the inclined-wedge die structure includes an upper die base, a lower die base, a primary double-action inclined-wedge structure, and two secondary double-action inclined-wedge structures; the primary double-action inclined-wedge structure includes a primary sliding block disposed on thelower die base, a first-side flanging portion disposed on the primary sliding block, a first-side integral drive block disposed on the primary sliding block, a primary drive block disposed on the upper die base, a first-side integral inclined wedge disposed on the upper die base, and a first-side integral insert block disposed on the first-side integral inclined wedge; the secondary double-actioninclined-wedge structure includes a secondary sliding block disposed on the primary sliding block, a second-side flanging portion disposed on the secondary sliding block, a second-side integral driveblock disposed on the secondary sliding block, a secondary drive block disposed on the upper die base, a second-side integral inclined wedge disposed on the upper die base in sliding, and a second-side integral insert block disposed on the second-side integral inclined wedge. In one step, the structure of the present invention can complete flanging at a front bumper of the outer panel of the automotive front cover and at two headlamps.

Description

technical field [0001] The invention relates to a stamping die, in particular to a die structure for a wedge flange of an automobile front cover outer plate. Background technique [0002] At present, the flanging at the edge of the outer panel of the automobile front cover is realized by a double-action wedge structure, such as Figure 7 As shown, the double-action wedge structure includes a slide block 102 slidably arranged on the lower die 101, a lower drive block 104 arranged on the slide block 102, an upper drive block 103 arranged on the upper die, and a slide block 103 arranged on the upper die. The oblique wedge 105 on the upper mold, the side flange portion 107 arranged on the slider 102 , the side trimming insert 106 arranged on the oblique wedge 105 and the reset cylinder arranged between the slider 102 and the lower mold 101 . When working, the upper mold moves downward, the upper driving block 103 first drives the slider 102 to slide to the working position, and ...
