Abstract

The invention relates to a technological process for improving the rigidity of the skylight part on a car roof, which comprises drawing, trimming and flanging procedures. The technological process is characterized in that in the trimming procedure, a processing concave bar and a plurality of processing concave envelopes are formed on folded surfaces around the skylight on the roof; and in the flanging procedure, the processing concave envelopes are flattened and the processing concave bar is remained. The technological process for improving the rigidity of the skylight part on the car roof provided by the invention has the advantages of less processing steps, simple operation and greatly enhanced horizontal and longitudinal rigidity of the skylight part on the car roof.

Description

A kind of process that improves position, the skylight rigidity of car roof
Technical field
The present invention relates to a kind of Sheet Metal Forming Technology method of car parts, relate in particular to a kind of process that improves position, the skylight rigidity of car roof.
Background technology
As everyone knows, position, car skylight is one of the most yielding position.And the area of car roof is very big, but generally is not do the intensity examination, and mostly material thickness generally is 0.7mm or 0.8mm; In the face of big area like this, and so thin material, position, car skylight rigidity is not enough naturally; Add skylight annex gravity effect, after operation after a while, position, top cover skylight distortion occurs through regular meeting; Cause roof leaking, leak, have a strong impact on the use of user car.
Chinese patent CN101633017A discloses a kind of process for stamping of avoiding plate corner part in car door from wrinkling; Replenish through increasing the technology convex tendon when the drawing operation moulding; Realized the shape in inner plate of car door bight is all drawn out; Only whole root fillet during the postorder shaping; Thereby reduced subsequent handling shaping amount, changed present industry shallow recessing, big shaping traditional handicraft way and drawn the difficult technical barrier of easy shaping, efficiently solved the long-term puzzlement of traditional handicraft and the wrinkling problem of insurmountable product.But this method can not increase the horizontal and vertical rigidity of parts.
Summary of the invention
The present invention mainly is the technical problem that solves position, existing in prior technology car skylight rigidity deficiency etc.; A kind of process that improves position, the skylight rigidity of car roof is provided; Make the horizontal and vertical rigidity in position, skylight of car roof strengthen greatly; And processing step is less, and is simple to operate.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: it comprises drawing operation, trimming process step and overturning process; It is characterized in that; In described trimming process step, on the turnover face around the top cover skylight, mold technology concave bar and the recessed bag of some technology; In overturning process, the recessed bag of technology is flattened, the technology concave bar keeps.Rigidity to the top cover skylight is not enough, not increasing cost, does not change under the situation of material, has only from Sheet Metal Forming Technology and thinks method.The processing technology concave bar makes the lateral stiffness at position, car skylight increase; Downwards flatten recessed bag during flange, make the compression of material plasticity, to increase the vertical rigidity in position, car skylight.
As preferably, said technology concave bar laterally is pressed into strip on said turnover face.Be convenient to processing like this, and less for the influence of turnover face.
As preferably, the width of said technology concave bar is pressed into 1mm to 5mm, and the degree of depth of said technology concave bar is pressed into 0.5mm to 3mm.
Further, as preferably, the width of said technology concave bar is pressed into 2mm to 4mm, and the degree of depth of said technology concave bar is pressed into 1mm to 2mm.
As preferably, said technology is recessed to wrap in vertically compacting on the said turnover face.The recessed wrap molding of technology is at turnover face middle part, and is also plastic on the base.
As preferably, the degree of depth of the recessed bag of said technology is pressed into 2mm to 4mm.
As preferably, the distance between adjacent two recessed bags of said technology is 10mm to 50mm.
As preferably, said technology is recessed to wrap on the said turnover face equidistance and arranges.Make that like this Stiffness Distribution gets more even on the turnover face.
The beneficial effect that the present invention brings is, position, skylight rigidity is strengthened greatly, and the top cover pressure-bearing doubles, and technology is simple, and is easy to process, is worthy to be popularized.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the top cover handled of the present invention;
Accompanying drawing 2 is a kind of structural representations of the top cover behind the trimming process step of the present invention;
Accompanying drawing 3 is a kind of structural representations of turnover face of the top cover of processing of the present invention.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of invention.
Embodiment: a kind of process that improves position, the skylight rigidity of car roof of present embodiment like Fig. 1, shown in 2, comprises drawing operation; Make the abundant extension of material; Carry out trimming process step then, remove unnecessary rim charge, in trimming process step; Turnover face 2 around along top cover 1 skylight molds the strip technology concave bar 21 that four width are 3 mm, the degree of depth 1.5 mm; Technology concave bar 21 on the adjacent surface is vertical each other, and vertically extrudes the recessed bag 22 of technology of a plurality of spacing 30 mm, the degree of depth 3 mm, the similar triangle in cross section of the recessed bag 22 of technology along the base at turnover face; In overturning process, the recessed bag 22 of technology is flattened, and technology concave bar 21 keeps, as shown in Figure 3, after the recessed bag 22 of technology flattened, the recessed bag of technology that has stayed a plurality of planes at turnover face 2 printed 23, and the technology concave bar 21 of this moment is retained in turnover face 2 tops.
