Embodiment 1

[0041] An embodiment of the present invention provides a stamping die for an automobile roof cover, see Figure 1-Figure 5 , the stamping die includes: an upper mold base 1, a lower mold base 2, a wedge 3, a pressing core 4 and a trimming tool 11;

[0042] The inclined wedge 3, the pressing core 4 and the trimming tool 11 are all located between the upper mold base 1 and the lower mold base 2, the inclined wedge 3 is arranged on the lower mold base 2, and the pressing core 4 and the trimming tool 11 are installed on the lower mold base 2 on;

[0043] The upper end of the wedge 3 is provided with an upper slope 301 and a vertical surface 302, the vertical surface 302 intersects with the top of the upper slope 301, and the vertical surface 302 is aligned with the cutting edge of the trimming tool 11;

[0044] The lower end surface of the die core 4 includes a first end surface 41 and a second end surface 42, and the second end surface 42 is aligned with the upper slope 301 of t...

Embodiment 2

[0097] The embodiment of the present invention also provides an automobile roof processing equipment, the processing equipment includes the automobile roof stamping die described in the first embodiment.

[0098] The automobile roof processing equipment provided by the embodiment of the present invention includes the automobile roof stamping die described in Embodiment 1. Through the automobile roof stamping die, the processing equipment can reduce the manufacturing process of the automobile roof and shorten the manufacturing process. time and increase production efficiency. Moreover, because the development cost of the automobile roof stamping die described in the first embodiment is relatively low, the cost of the processing equipment is reduced.

Abstract

The invention discloses an automobile roof stamping die and machining apparatus and belongs to the technical field of automobile stamping. The stamping die comprises an upper die base, a lower die base, a wedge, a presser core and a trimming tool; the upper end of the wedge is provided with an upper bevel and a vertical plane; the lower end of the presser core includes a first end surface and a second end surface; in operation, an automobile roof to be reshaped is placed on the upper ends of the lower die base and the wedge, a cutting edge of the trimming tool is aligned with a tail edge and scrap edge joint included in the automobile roof to be reshaped, the upper die base is driven to move down, the first end surface of the presser core press-fits a formed edge included in the automobile roof to be reshaped onto the lower die base, and the trimming tool cuts off the scrap edge; the wedge is driven to move up, the upper bevel attaches to the second end surface of the presser core so as to extrude the tail edge to form an upper turnup.Trimming and up-turning may be finished with only one stamping die of the invention, manufacture process of the automobile roof is shortened, manufacture time is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile stamping, in particular to an automobile roof stamping die and processing equipment. Background technique [0002] In cars with tailgates, the roof needs to be shaped at its rear during machining. Before reshaping, see figure 1 , the car roof to be reshaped includes the forming side AB, the tail side BC and the scrap side CD that are connected in sequence. Drop the scrap edge CD and turn up the tail edge BC to form the upper turn edge BE. [0003] In the prior art, the automobile roof processing equipment has two kinds of stamping dies, one is a stamping die for trimming, which is used to cut off the waste edge CD, and the other is a stamping die for flanging. Used to turn up the tail edge BC to form the upper edge BE. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] At present, the trim...
