Abstract
Floor drawing work in a kind of car comprising part, binder surface, bead and rear process trimming line；The periphery of part has flange shape, part flange shape is the foundation of the binder surface design, i.e. part flange shape should be located on the binder surface, cancel technique supplement moulding bead between part type face and binder surface to be located on the binder surface, bead selects hierarchic structure, and the flowing of plate is controlled by adjusting hierarchic structure numbers of steps, shape and fillet size.Trimming line is located on the binder surface, and trimming line is between bead and part flange shape, close to bead side.The present invention supplements moulding, selects unilateral hierarchic structure bead and makes trimming line close to the methods of bead as far as possible by cancelling technique, significantly improves the stock utilization of sheet stamping forming.It realizes that stock utilization promotes 22% after adopting this method, while reducing the material cost of part in floor in car mentioned in the present invention.
Description
Technical field
The present invention relates to process for stamping and forming, it is specifically related to floor drawing work in a kind of car.
Background technique
Drawing work is widely applied in coachbuilt body punching production, especially adapts to the production of complicated shape part.Relatively
In forming technology, parts quality can be better ensured that.
But traditional drawing work trimming line designs binder surface other than parts profile, in part and pressure on drawing punch
Moulding is supplemented using technique between charge level, brings that stock utilization is low, the high problem of manufacturing cost.
Summary of the invention
The purpose of the present invention is the problems low for traditional drawing work stock utilization, supplement moulding by cancelling technique
Deng proposing a kind of middle floor drawing work for effectively improving stock utilization.
Floor drawing work in a kind of car comprising part, binder surface, bead and rear process trimming line.
The part is characterized in that periphery has a flange shape, the part flange shape be binder surface design according to
According to that is, described part flange shape should be located on the binder surface, cancel technique between part type face and binder surface and supplement moulding.
And traditional drawing work designs between part type face and binder surface technique supplement, addendum needs to reduce after forming
Fall, stock utilization is caused to reduce.
The bead is located on the binder surface, and the bead selects hierarchic structure, by adjusting hierarchic structure platform
Order amount, shape and fillet size control the flowing of plate.And the bead shape of traditional drawing work is semicircle or side
Shape, compared with unilateral hierarchic structure bead, traditional draw-bead structure size is big, causes stock utilization low.
The trimming line is located on the binder surface, and the trimming line leans between bead and part flange shape
Nearly bead side.And the trimming line of traditional drawing work is located between technique supplement and part flange shape.
Beneficial effects of the present invention:
The present invention supplements moulding, selects unilateral hierarchic structure bead and leans on trimming line as far as possible by cancelling technique
The methods of nearly bead, significantly improves the stock utilization of sheet stamping forming.Floor in car mentioned in the present invention, is adopted
22% is promoted with realization stock utilization after this method, while reducing the material cost of part.
Detailed description of the invention
Fig. 1 is floor panel structure schematic diagram in car.
Fig. 2 is drawing work schematic diagram of the present invention.
Fig. 3 is the sectional view of Fig. 2
Fig. 4 is traditional drawing work figure.
Fig. 5 is the sectional view of Fig. 4.
Specific embodiment
As shown in Figures 1 to 5, floor drawing work in a kind of car comprising part 1, binder surface 2, bead 3 and
The trimming line 4 of process afterwards；
The periphery of the part 1 has flange shape 11, and part flange shape 11 is the foundation that the binder surface 2 designs,
I.e. part flange shape 11 should be located on the binder surface 2, cancel technique between 1 type face of part and binder surface 2 and supplement 5 moulding.
And traditional drawing work design between 1 type face of part and binder surface 2 and has technique to supplement 5, technique supplements 5 parts needs after forming
Reduction is fallen, and stock utilization is caused to reduce.
The bead 3 is located on the binder surface 2, and bead 3 selects hierarchic structure 31, by adjusting hierarchic structure 31
Numbers of steps, shape and fillet size control the flowing of plate.And 3 shape of bead of traditional drawing work is semicircle 32
Or it is rectangular, compared with unilateral 31 bead of hierarchic structure, traditional draw-bead structure size is big, causes stock utilization low.
The trimming line 4 is located on the binder surface 2, trimming line 4 between bead 3 and part flange shape 11,
Close to 3 side of bead.And the trimming line 4 of traditional drawing work is located between technique supplement 5 and part flange shape 11.
The present invention supplements 5 moulding, selects unilateral 31 bead of hierarchic structure and makes deburring as far as possible by cancelling technique
Line 4 significantly improves the stock utilization of sheet stamping forming close to the methods of bead 3.In car mentioned in the present invention
It realizes that stock utilization promotes 22% after adopting this method, while reducing the material cost of part in floor.
