The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
As shown in Figure 1, the cupping tool of the Car Front Door Panels that provides for the utility model, comprise punch (not shown) and die 1, die 1 is provided with the forming area 2 of Car Front Door Panels, forming area 2 comprises door-plate forming area 21 and doorframe forming area 22, and the outside of the arc area 221 of corresponding doorframe forming area 22 is provided with the first bead 3 on die 1.
The cupping tool of the Car Front Door Panels that the utility model provides, since in the arranged outside of the arc area 221 of doorframe forming area 22 the first bead 3, therefore in the drawing process of Car Front Door Panels, the first bead 3 can be controlled and draw the charging resistance, guarantee that plate is fully drawn, avoid wrinkling at the arc area of doorframe.Solved the wrinkling problem of doorframe arc area that existing cupping tool causes Car Front Door Panels easily.
Such as Fig. 3 and shown in Figure 7, as the further improvement of above-described embodiment, the first bead 3 longitudinally is made of the different bead section of multistage cross section (31,32,33).Multistage bead section (31,32,33) forms stepped bead 3, and is different by the bead cross sectional dimensions, the control plate draw the charging resistance.Phase equal cross section bead adopts the variable cross-section bead, can be according to the different moulding degree of depth, and the size of control draw restraining force makes each part material reduction of workpiece even, avoids wrinkling or cracking.In the present embodiment, each bead section length L 1, L2, L 3 longitudinally can be different with the moulding degree of depth concrete definite according to the size of workpiece.And the utility model is not limited to three sections bead sections, and the number of concrete bead section can be different with the moulding degree of depth concrete definite according to the size of workpiece.
Particularly, as shown in Figure 3, the cross sectional dimensions of the bead section 31 of the first bead 3 corresponding arc areas 221 is greater than the cross sectional dimensions of adjacent bead section (31,32).This is that therefore, this position is the bead section 31 of C-C by larger cross section because the moulding degree of depth of arc area is larger, increases and walks to expect resistance, ensures that plate is fully drawn.Simultaneously, adjacent smaller cross-sectional area is that 32 pairs of chargings of bead section of B-B replenish, along with the moulding degree of depth is constantly deepened, with cross section be that the adjacent less cross section of the bead section 32 of B-B is that 33 pairs of plates of bead section of A-A carry out secondary supplement.Control the wrinkling degree of workpiece by the delivery speed of varying cross-section size restrictions different phase, thereby it is wrinkling to play the inhibition workpiece, improves the purpose of quality.
Such as Fig. 4-shown in Figure 6, the cross section of the bead section of the first bead in above-described embodiment is arc, and radius is respectively R1, R2, R 3, highly is respectively H1, H2, H 3.In other embodiment of the present utility model, different depending on the size of plate size and the moulding degree of depth, the cross section of each described bead section also can for rectangle trapezoidal or wherein arbitrarily the two or three longitudinally with the combination of random order.
Further, be smooth transition between each described bead section of the first bead in above-described embodiment.This can be by being that the fillet of R is found out such as Fig. 4-radius shown in Figure 6.Can make like this each described bead section that the control of delivery speed is able to smooth transition, prevent that effectively workpiece is wrinkling.
Preferably, as depicted in figs. 1 and 2, described cupping tool comprises also that the second bead 4, the second draws along muscle 4 and is located at described the first bead 3 along the outside of forming area 2.Can further increase like this and walk the material resistance, it is even to guarantee to walk material.Preferably, the spacing of the first bead and the second bead is 2cm.
Wherein the cross section of described the second bead in above-described embodiment longitudinally can be uiform section or variable cross-section, specifically can determine according to size and the different of the moulding degree of depth of plate size.
Described cupping tool in above-described embodiment can also comprise blank holder in addition, and described blank holder is located between described punch and the described die.Can prevent like this transverse shifting of plate blank material when tension, have influence on the pull and stretch of workpiece.
Secondly, as shown in Figure 1, described cupping tool can also comprise guide plate, and described guide plate is divided into the first guide plate 5 and the second guide plate (not shown), and the first guide plate 5 is located on the die 1, and described the second guide plate is located on the described blank holder.The setting of described guide plate is in order to provide guiding to mould, in order to avoid produce deviation, to affect workpiece quality.
As depicted in figs. 1 and 2, for the further improvement of above-described embodiment, described cupping tool can also comprise a plurality of balance weights 6, balance weight 6 be located at shaped region 2 around.This is in order to guarantee the producing balanced forces of forming area 2.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
