Abstract
The invention discloses an anti-cracking forming method of an automobile cavity-shaped internal covering piece corner part. In the method, in the process of drawing a platy material into a finished piece with a high end part and a low end part, corresponding to the cavity-shaped internal covering piece corner part, a convex hull shaped absorbing rib used for absorbing excess materials is formed on an inner swaging surface of the lower end part in a drawing mode, wherein the convex hull shaped absorbing rib can absorb the excess materials to ensure that the materials flow inside smoothly so as to solve the problem of vertical wall cracking between the high end part and the low end part of the finished piece; and the wrinkling of the high end part is obviously improved because the material absorbed by the vertical wall is reduced.
Description
Technical field
The present invention relates to a kind of cracking situation appears in automobile chamber shape internal covering part easily in forming process drawing method that solves.
Background technology
In the chamber shape part window frame of tailgate inner panel, inner plate of car door (especially with) the draw forming process, tetrapod is easy to crack, and top area creases easily.
Plate parts belongs to the category-B spare in the automobile panel in the tailgate, has complex-shaped, characteristics such as the hole is many, drawing depth is big, difficult shaping.Be shaped at inner window, the Sheet Metal Forming Technology scheme of industry general implementation is at present: in order to reduce the shaping degree of depth, the product flange face is directly as binder surface during drawing modeling.Adopt flowing of bead control material, the benefit designer of this scheme is when the Sheet Metal Forming Technology shape-designing, fairly simple, the efficient height, its maximum drawback has been ignored the quality control of product forming process exactly, by the design feature decision of product own, four bights of inner window are in forming process, the plane strain inequality that material is subjected to, wherein the strain of both direction very easily causes tearing greater than attribute rated value own; Top area is because of suction in the wall shaping, and plate moves inequality obvious wrinkle.Therefore, the Sheet Metal Forming Technology scheme of science and shape-designing are extremely important for mould development success or not, cost height, quality quality.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shape internal covering part bight, automobile chamber anti-cracking manufacturing process that can effectively prevent the product cracking in drawing process.
For solving the problems of the technologies described above, technical scheme of the present invention is: shape internal covering part bight, automobile chamber anti-cracking manufacturing process, board-like material is drawn in the process of the product that becomes to have high end and end portion, on the interior binder surface of described end portion and shape internal covering part bight, corresponding described chamber draw forming be useful on the convex closure shape suction muscle that absorbs excess stock.
As a kind of optimized technical scheme, described convex closure shape suction muscle is to high end direction epirelief.
As a kind of optimized technical scheme, the height of described convex closure shape suction muscle is 2%～4% of a high end height.
Owing to adopted technique scheme, shape internal covering part bight, automobile chamber anti-cracking manufacturing process, board-like material is drawn in the process of the product that becomes to have high end and end portion, on the interior binder surface of described end portion and shape internal covering part bight, corresponding described chamber draw forming be useful on the convex closure shape suction muscle that absorbs excess stock, described convex closure shape suction muscle can absorb unnecessary material, guarantees that material flows into smooth and easy and high end and the cracking of the wall between the end portion problem solution product; High end also can be because of the wall suction reduces, wrinkling be improved significantly.
Description of drawings
Fig. 1 is a product schematic diagram of producing the automobile back door inner panel according to this method invention;
Fig. 2 is along A-A directional profile enlarged drawing among Fig. 1;
Among the figure: 1-convex closure shape suction muscle; Binder surface in the 2-.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the present invention.In the following detailed description, only some one exemplary embodiment of the present invention has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under situation without departing from the spirit and scope of the present invention, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
Shape internal covering part bight, automobile chamber anti-cracking manufacturing process, board-like material is drawn in the process of the product that becomes to have high end and end portion, on the interior binder surface 2 of described end portion and shape internal covering part bight, corresponding described chamber draw forming be useful on the convex closure shape suction muscle 1 that absorbs excess stock, described convex closure shape suction muscle 1 is to high end direction epirelief, and the height of described convex closure shape suction muscle 2 is 2%～4% of a high end height.
In order to further specify this shape internal covering part bight, automobile chamber anti-cracking manufacturing process, enumerate two specific embodiments below.
Embodiment one:
As depicted in figs. 1 and 2, automobile back door inner panel window frame bight anti-cracking manufacturing process, in the forming process of automobile back door inner panel, need the raw material (board-like material) of automobile back door inner panel to draw the product that becomes to have high end and end portion, promptly form the window frame shape, on the interior binder surface 2 of described end portion and corresponding described automobile back door inner panel window frame bight draw forming be useful on the convex closure shape suction muscle 1 that absorbs excess stock, described convex closure shape suction muscle 1 is to the high extreme direction epirelief of automobile back door inner panel window frame, and the height of described convex closure shape suction muscle 1 is 2%～4% of a described window frame height.
Embodiment two:
Please refer to accompanying drawing 1 and accompanying drawing 2,, be applicable to that the partial structurtes of the inventive method are similar to though the global shape of arrangements for automotive doors inner panel and automobile back door inner panel is different.Specifically, arrangements for automotive doors inner panel window frame bight anti-cracking manufacturing process, in the forming process of automobile back door inner panel, need the raw material (board-like material) of automobile back door inner panel to draw the product that becomes to have high end and end portion, promptly form the window frame shape, on the interior binder surface 2 of described end portion and corresponding described arrangements for automotive doors inner panel window frame bight draw forming be useful on the convex closure shape suction muscle 1 that absorbs excess stock, described convex closure shape suction muscle 1 is to the high end direction epirelief of arrangements for automotive doors inner panel window frame, and the height of described convex closure shape suction muscle 1 is 2%～4% of a described window frame height.
Particularly, in the shape internal covering part process of draw forming automobile chamber, when the inner window moulding, binder surface 2 zone design increase convex closure shape suction muscle 1 technology in the bight, this convex closure shape suction muscle 1 storage material when patrix begins to contact binder with binder surface, the height of this convex closure shape suction muscle 1 is a wall height 2%～4%, in the manufacture process of inner plate of car door, selects for use 3% just can guarantee that material flows into smooth and easy and solution wall cracking problem; The high end of automobile chamber shape internal covering part also can be because of the wall suction reduces, wrinkling be improved significantly.
