Abstract
The utility model relates to a shaping switching device in a stamping forming die for automobile sheet metal parts, which comprises two male dies, male die guide blocks, male die driving blocks, a driving block cover plate and a driving cylinder. The shaping switching device is mounted on the stamping forming die and can be used for stamping and forming two types of sheet metal parts, namely sheet metal parts with front convex hulls and rear pits, and sheet metal parts with front pits and rear convex hulls, thereby saving the stamping forming die and reducing the cost of the die; and the shaping switching device is simple in structure and stable and reliable in working.
Description
Technical field
The utility model relates to the shaping switching device shifter in the punch-forming mold of automobile metal plate work.
Background technology
There is a kind of sheet metal component to be provided with two convex closures in the sheet metal component of automobile, two convex closures lay respectively at the tow sides of sheet metal component, as shown in Figure 1 and Figure 2, thereby the two sides at sheet metal component all forms the shape of " protruding is recessed ", and this kind sheet metal component is stamping forming by the sheet metal component as shown in Figure 3 of last procedure institute moulding.The sheet metal component of " one protruding one is recessed " shape has two types, a kind of for before the same one side epirelief of sheet metal component wraps in, pit (being the shape at another convex closure back side) after, another kind is that a same fovea superior of sheet metal component is cheated preceding, convex closure after, like this, when these two kinds of sheet metal components of punching press, just need two molds, and every mold cost is about about 500,000, so increased the cost of automobile product.
Summary of the invention
The purpose of this utility model provides a kind of shaping switching device shifter of punch-forming mold, it is installed in the punch-forming mold of above-mentioned sheet metal component, only need a mold, be plastic above-mentioned with before simultaneously epirelief wraps in, pit after, and pit is preceding, convex closure after two types sheet metal component.
The shaping switching device shifter of punch-forming mold described in the utility model, form by two punch, punch guide pad, punch drive block, drive block cover plate and driving cylinder, offer breach in punch guide pad bottom, on the punch guide pad, offer two pilot holes, two pilot holes are communicated with described breach, and two punch lay respectively in two pilot holes and the pilot hole matched in clearance; The punch drive block is a cuboid, and its upper surface is provided with two boss, and two boss lay respectively at the place, diagonal angle of cuboid, and the upper surface of two boss is by inclined-plane on the boss and the smooth connection of punch drive block upper surface; The drive block cover plate is fixed on the punch drive block, offer two strip grooves on it, article two, the strip groove lay respectively at two boss directly over, punch drive block and drive block cover plate are arranged in the breach and this breach matched in clearance of punch guide pad, the lower end of two punch lays respectively in two strip grooves of drive block cover plate, and be supported on the punch drive block, the punch drive block is connected with the piston rod that drives cylinder.
Two punch are the cylinder bodily form, laterally offer spacing breach on the punch periphery, and punch guide pad upper surface is fixed with limited block, and a side of limited block is arranged in described spacing breach, and fit with spacing breach bottom surface.
The effect of limited block mainly is to limit the circumferential position of cylinder bodily form punch in the punch guide pad, and punch can not be rotated in the pilot hole of punch guide pad; Its another effect be limit cylinder bodily form punch with respect to the punch guide pad along the axially movable distance of punch, in carrying, installation process, punch can not dropped out from the punch guide pad.In order to guarantee the axially movable distance of punch, the width of spacing breach should be greater than the thickness of limited block.
Be fixed with cushion block two punch lower ends with arc outline, this cushion block is owing to have the arc outline, so punch is slided between punch drive block upper surface and boss upper surface, and carry out contact wear by cushion block and punch drive block, can avoid the frequent replacing of punch.
During use, punch guide pad and driving cylinder are fixed on the die shoe of punch-forming mold, offer two through holes on the counterdie eccentric swage of punch-forming mold, two punch can pass from two through holes.Cylinder drives the punch drive block and the drive block cover plate moves around in the breach of punch guide pad with driving, thereby make two punch under the effect of two boss of punch drive block, move along its axial alternatively up and down, before so both but punch forming had wrapped in the one side epirelief, pit after sheet metal component, but again punch forming with fovea superior hole preceding, convex closure after sheet metal component.
Shaping switching device shifter described in the utility model is installed on the punch-forming mold, before can punch forming wrapping in the one side epirelief, pit after, and pit is preceding, convex closure after two types sheet metal component, thereby saved one the cover punch-forming mold, reduced die cost; This shaping switching device shifter is simple in structure, and working stability is reliable.

Fig. 6 is that this shaping switching device shifter is installed in the cross-sectional schematic on the punch-forming mold.
The specific embodiment
As shown in Figure 4 and Figure 5, the shaping switching device shifter of this punch-forming mold is made up of two punch 1, punch guide pad 6, punch drive block 5, drive block cover plate 3 and driving cylinder 4, offer breach 8 in punch guide pad 6 bottoms, on punch guide pad 6, offer two pilot holes 7, two pilot holes 7 are communicated with described breach 8, two punch 1 are the cylinder bodily form, lay respectively in two pilot holes 7 and pilot hole 7 matched in clearance.
Laterally offer spacing breach 9 on punch 1 periphery, punch guide pad 6 upper surfaces are fixed with limited block 2, and a side of limited block 2 is arranged in described spacing breach 9, and fit with spacing breach 9 bottom surfaces, and the width of spacing breach 9 is greater than the thickness of limited block 2.
The lower end of two punch 1 lays respectively in two strip grooves 10 of drive block cover plate 3, the lower end of two punch 1 is fixed with the cushion block 12 with arc outline, punch 1 is supported on the punch drive block 5 by cushion block 12, and punch drive block 5 is connected with the piston rod that drives cylinder 4.
As shown in Figure 6, with the punch guide pad 6 of shaping switching device shifter 15 with drive cylinder 4 and be fixed on the die shoe 16 of punch-forming mold, offer two through holes on the counterdie eccentric swage 14 of punch-forming mold, two punch 1 can pass from two through holes.Cylinder 4 drives punch drive block 5 and drive block cover plate 3 moves around in the breach 8 of punch guide pad 6 with driving, thereby makes two punch 1 under the effect of two boss 11 of punch drive block 5, moves along its axial alternatively up and down.
