Embodiment

[0046]Such asFigure 6 ,Figure 7 As shown, the lower mounting model surface adjustment block 4 is assembled on the lower model surface to install the base surface A in accordance with the mounting gap jx1 / jx2 / jx3 / jx1 / jx1 / jx2 / jx3 / jx4 and by screw 6 and pin 7.

[0047]Such asFigure 8 As shown, the upper surface of the lower mold surface is the upper surface of the lower mold surface, which is the working surface T of the entire block, is an integrated surface. Work surface width B1, the lower model surface adjusts the air open distance L1 of the block surface, and the depth of the vertical space is K. The lower model surface adjusts the width B0 of the block along the horizontal direction to completely cover the lower mold width B1. The lower model surface is adjusted on the block surface, which is convenient to reduce the adjustment pad 5 to reduce the adjustment pad 5 adjustment, and avoid the air open surface higher than the lower model surface. The working surface T affe...

Abstract

The invention relates to a flanging die for eliminating surface fluctuation of a body-side sheet oil tank opening. The flanging die comprises an oil tank opening pressing molded surface, a lower maledie molded surface and a lower die molded surface adjusting block, wherein the lower die molded surface adjusting block is fixed to a lower die molded surface adjusting block mounting base surface ofthe lower male die molded surface and is provided with an open molded surface, the finishing workload is reduced when the height of the open molded surface is adjusted by adding a gasket, and meanwhile the situation that the effective supporting effect of the oil tank opening molded surface is influenced due to the fact that the open molded surface is higher than a working surface of the lower diemolded surface adjusting block is avoided; and after a body-side sheet process part with increased finishing contour length after punching of the oil tank opening is placed in the flanging die, the stamped part automatically falls into a theoretical position of the lower male die molded surface of the flanging die, and effective control over materials in a non-deformed area of a flanging ridge area of the oil tank opening is realized through assembly of an upper die body and a lower die body of the flanging die. According to the flanging die, the workload of debugging and modification can bereduced, unqualified die molded surface data caused by repair welding modification can be avoided, and the problem of surface fluctuation of the body-side sheet oil tank opening is solved.

Description

Technical field[0001]The present invention belongs to the field of punching techniques, and more particularly to a stamping mold that does not require a replenishment, adjustable surface height, and more particularly to a flange mold that eliminates the surface of the lateral outer plate oil box.Background technique[0002]During the production of automobile stamping, the surface undulation of the surface of the outer plate oil box is the process defect, which belongs to the general problems, and the severe oil tank mouth surface undulation state is an unacceptable defect.[0003]In the prior art, after the surface of the outer surface of the outer plate fuel tank, after the flip-edge mold, the stamper automatically falls into the mold surface of the molded mold surface, and the width of the fuel tank port In the mold, the co-routing region of the surface of the oil tank opening can only optimize the surface undulating state after the oil tank opening, and cannot completely eliminate th...
