The invention relates to a stamping technology treatment method of a skylight on an automobile top cover. The stamping technology treatment method of the skylight on the automobile top cover comprises the working procedures of drawing, trimming and punching and flanging. The stamping technology treatment method of the skylight on the automobile top cover is characterized in that in the trimming and punching working procedure, a plurality of technology concave ribs are molded in advance between a trimming line (21) and the flanging line (22) of the skylight (2); in the flanging working procedure, the plurality of technology concave ribs are turned to be leveled so as to release the stress on the flanging surface and prevent the automobile top cover from being deformed because of centralized stress; the technology concave ribs comprise bar-shaped technology concave ribs (23) and triangle technology concave ribs (24); one or more bar-shaped technology concave ribs (23) are distributed in parallel to the trimming line (21); and the triangle technology concave ribs (24) are uniformly distributed between the trimming line (21) and the bar-shaped technology concave ribs (23) closest to the trimming line (21), and are of triangle groove structures.
Description
Technical field
The invention belongs to automobile metal plate work punch process forming field, be specifically related to a kind of Sheet Metal Forming Technology processing method of skylight on automobile top cover.
Background technology
At present in the Punching Process of skylight on automobile top cover, when carrying out flange to skylight, because the stress in flange face does not obtain enough release, stress is made to concentrate in top cover surface, thus cause automobile top-cap flange to be out of shape, flange distortion is the technical barrier that domestic and international automobile industry is difficult to overcome, flange distortion can affect the attractive in appearance of automobile top-cap, skylight even can be caused to stay, in prior art, each mould enterprise can only alleviate flange distortion by product-forming or raising Making mold precision, but all can not thoroughly eliminate.
Summary of the invention
The present invention devises a kind of Sheet Metal Forming Technology processing method of skylight on automobile top cover, which solves the automobile top-cap flange caused when carrying out flange to skylight and is out of shape thus affects the attractive in appearance of automobile top-cap, even can cause the problem that skylight is stayed.
In order to solve the technical problem of above-mentioned existence, present invention employs following scheme:
A kind of Sheet Metal Forming Technology processing method of skylight on automobile top cover, comprise drawing operation, trimming and piercing die operation and overturning process, deep drawing of sheet is molded into automobile top-cap (1) in drawing operation, the waste material that automobile top-cap (1) is unnecessary is cut off in trimming and piercing die operation, and skylight (2) is gone out on automobile top-cap (1), it is characterized in that: in described trimming and piercing die operation, between the trimming line (21) in skylight (2) to flange line (22), mold multiple technique concave bar in advance; In described overturning process, by multiple technique concave bar down tilt, avoid automobile top-cap stress to concentrate with the stress discharged on flange face and be out of shape.
Further, technique concave bar comprises strip technique concave bar (23), and one or more strip technique concave bar (23) is parallel to trimming line (21) distribution.
Further, strip technique concave bar (23) wide 1mm-5mm, dark 1mm-3mm.
Further, technique concave bar also comprises triangle technique concave bar (24), and triangle technique concave bar (24) is distributed on trimming line (21) and between the nearest strip technique concave bar (23) of trimming line (21), triangle technique concave bar (24) is in triangle groove structure.
Further, triangle technique concave bar (24) dark 1mm-3mm, interval 30mm between adjacent triangle technique concave bar (24).
The Sheet Metal Forming Technology processing method of this skylight on automobile top cover has following beneficial effect:
(1) in trimming and piercing die operation of the present invention, strip technique concave bar is molded in advance between trimming line in skylight to flange line, in overturning process, by strip technique concave bar down tilt, automobile top-cap stress is avoided to concentrate with the stress discharging vertical flange line direction on flange face.
(2) in trimming and piercing die operation of the present invention, trimming line in skylight to and between the nearest strip technique concave bar of trimming line, mold multiple triangle technique concave bar in advance, in overturning process, by its down tilt, automobile top-cap stress is avoided to concentrate to discharge stress flange face being parallel to flange line direction.
(3) the present invention molds strip technique concave bar and triangle technique concave bar in advance between skylight trimming line to flange line, by its down tilt in overturning process, make the intensity in flange face obtain obvious reinforcement, and then the deadweight avoided due to automobile top-cap cause skylight to be stayed.
(4) the present invention does not need to increase stamping procedure, and cost does not need to increase yet, and therefore can be widely used in automobile top cover die and manufacture field.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
A Sheet Metal Forming Technology processing method for skylight on automobile top cover, comprises drawing operation, trimming and piercing die operation and overturning process.According to design, deep drawing of sheet is molded into automobile top-cap 1 in drawing operation, plate is fully stretched, in trimming and piercing die operation, cut off the waste material that automobile top-cap 1 is unnecessary, automobile top-cap 1 is gone out skylight 2, mold in advance between trimming line 21 to the flange line 22 at position, skylight 2 simultaneously four parallel with trimming line 21, width is 1 mm-5mm, the strip technique concave bar 23 of degree of depth 1mm-3mm, trimming line 21 at position, skylight 2 molds multiple triangle technique concave bar 24 in advance between the nearest strip technique concave bar 23 of trimming line 21, adjacent triangle technique concave bar 24 spacing 30mm, triangle technique concave bar 24 is in triangle groove structure, about degree of depth 1mm-3mm, as Fig. 1, shown in Fig. 2, in overturning process, by triangle technique concave bar 24 and strip technique concave bar 23 down tilt, the automobile roof structure schematic diagram after overturning process as shown in Figure 3.
Owing to molding strip technique concave bar 23 and triangle technique concave bar 24 in advance between position, skylight 2 trimming line 21 to flange line 22, by its down tilt in overturning process, the stress in flange face is made to have enough release, avoid stress concentration on automobile top-cap 1, and then be out of shape after avoiding automobile top-cap 1 flange, the intensity in flange face obtains obvious reinforcement simultaneously, and then the deadweight avoided due to automobile top-cap causes skylight 2 to be stayed, owing to not needing to increase stamping procedure, cost does not need to increase yet, and therefore can be widely used in automobile top cover die and manufacture field.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
