Description
Technical field
The utility model relates to the drawing die of automobile component, and specifically a kind of patrix is with the drawing die of interior material pressing core.
Background technology
The drawing die of existing automobile component, its structure generally has patrix, blank holder, counterdie, lower bolster.The parts narrow when middle position add man-hour by drawing die, and it is out of control easily to stretch, and narrow positions is wrinkling in the middle of usually can causing, and product surface quality is defective.Also be difficult for guaranteeing product surface quality by adjusting extensograph parameter.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, and the drawing die of a kind of patrix of rational in infrastructure, simple, easy to manufacture, long service life with interior material pressing core is provided.
The technical scheme that the utility model adopts is: a kind of patrix is with the drawing die of interior material pressing core, comprise patrix, blank holder, counterdie, lower bolster, blank holder is in the outside of counterdie, blank holder and counterdie are on lower bolster, the centre that it is characterized in that patrix is provided with interior guide plate, be provided with interior material pressing core in the inside of interior guide plate, be provided with nitrogen spring at interior material pressing core.
The utility model is rational in infrastructure, simple, and is easy to manufacture, easy to use, and the life-span is long, the surface quality of energy Effective Raise product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark among the figure: 1, patrix, 2, blank holder, 3, interior guide plate, 4, interior material pressing core, 5, nitrogen spring, 6, counterdie, 7, lower bolster.
The specific embodiment
By shown in Figure 1, a kind of patrix is with the drawing die of interior material pressing core, comprise patrix 1, blank holder 2, counterdie 6, lower bolster 7, blank holder 2 is in the outside of counterdie 7, blank holder 2 and counterdie 6 are on lower bolster 7, be provided with interior guide plate 3 in the centre of patrix 1, be provided with interior material pressing core 4 in the inside of interior guide plate 3, be provided with nitrogen spring at interior material pressing core.
After plate enters the mould location, patrix 1 is descending, patrix 1 is with after plate and blank holder 2 contact, continue descending, plate begins to stretch, the interior material pressing core 4 of guide plate 3 contacts with plate in the middle of the patrix 1, touches counterdie 6, along with the continuation that stretches, interior material pressing core 4 moves upward under the guide effect of interior guide plate 3 and is retracted into patrix, interior material pressing core 4 is subject to the pressure-acting of nitrogen spring 5, makes sheet metal stretching not out of control, eliminates thus the surface wrinkling phenomenon, when interior material pressing core lower surface flushes with upper mold cavity lower surface, blank holder arrives lowest limit position, stretches to finish, and can suppress the satisfactory part of surface quality.
Because plate is in whole drawing process, the middle part is subject to the pressure of interior material pressing core all the time, has eliminated the wrinkling that causes out of control that stretches, and has improved the surface quality of product.
