Detailed description of the invention
Core of the present utility model is to provide a kind of beam piece opening drawing die face, under the condition of two ends formability ensureing opening drawing, improves stock utilization and molding effect.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Please refer to 1 and Fig. 2, Fig. 1 be the structural representation of a kind of detailed description of the invention of beam piece opening drawing die face provided by the utility model; Fig. 2 is the partial enlarged drawing of the opening of beam piece shown in Fig. 1 drawing die face.
In a kind of detailed description of the invention, beam piece opening drawing die face provided by the utility model comprises two the long limits be oppositely arranged, two minor faces be oppositely arranged and process complementary surface 20; Wherein, described process complementary surface 20 comprises the first process complementary surface and the second process complementary surface, long limit described in two is respectively arranged with described first process complementary surface, described first process complementary surface stretches out along the tangential direction at product edge, and is provided with the bead 5 extended along its length; Minor face described in two is respectively arranged with the second process complementary surface, described second process complementary surface self-made components bottom section stretches out along described product edge tangent line direction, and has and connect the bottom section of described product and the step surface 7 of top area.
In FIG, blank line 1, blank shrinkage front 2, punch die parting line 3, product edge line 4, bead 5, product zone 10, process complementary surface 20.Wherein, blank shrinkage front 2 is product edge line after draw forming, punch die parting line 3 is the line of demarcation of punch and blank holder, in punch inner sleeve and pressure plate loop, due to blank by the die on blank holder and patrix by blank holding, bead 5 is arranged on the process complementary surface 20 of blank holder corresponding region.Product edge line 4 interior zone is product zone 10, and product edge line 4 outside is process complementary surface 20.
When draw forming, both sides longer for product first compress by die and blank holder, and then along with patrix continues to move downward, die and blank holder move downward jointly, and punch starts to be shaped; During shaping, width controls stream by the bead 5 on the first process complementary surface, length direction is controlled by second step surface 7 supplemented on face at two ends, can avoid that two ends blank is too fast internally to flow when being shaped, realize the stream controlling product length direction, thus under the condition of two ends formability ensureing opening drawing, improve stock utilization and molding effect.
Further, the top area of product stretches out preset length to form extension 6, the described step surface 7 of the downward-sloping formation in outer of described extension 6 along the edge tangent line direction of described product; Like this, the formation of step surface 7 is smooth-going and technical process simple, and the sidewall of step surface 7 tilts, can by changing the Slope angle adjustment charging rate of sidewall.
Above-mentioned step surface 7 is connected by connecting portion transition with bottom section, and described connecting portion is the arcuate structure with default chamfering; Like this, connected by connecting portion transition and can not only realize the smooth of step surface 7 and bottom section transition, and the adjustment of stream speed when can be realized by the angle of inclination changing the number of degrees of chamfering and the sidewall of step surface 7 being shaped, the chamfering number of degrees are less, charging is slower, two ends are shaped more abundant, and formability is better; The angle of inclination of sidewall is less, and more close to vertical plane, charging is slower, and two ends are shaped more abundant, and formability is better, can set suitable sidewall draft angles and the number of degrees of chamfering according to actual user demand.
Above-mentioned preset length is 5mm-7mm, also can set other length according to actual operation requirements, such as 5.5mm-8mm etc.; The number of degrees of above-mentioned chamfering and the angle of inclination of sidewall should be determined according to actual operation requirements, do not limit at this.
It is pointed out that ordinal numbers such as " first, second " described in literary composition is the different structure in order to distinguish same names, only for convenience, not representing certain order, more should not be construed as any restriction.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
