Description
Technical field
The utility model relates to a kind of automobile die, relates in particular to a kind of automobile panel layback and stretches mould.
Background technology
Drawing die is one of most popular mould in the punching production, and general drawing die all is to carry out forward to stretch, and does not relate to side direction and stretches.But Along with people's is to the diversified demand of car conour; Also increasingly high to the automobile panel shape need; Not only require to automobile panel stretch, task such as punching, flange, and more requirement has been proposed also the stamping position and the direction of automobile panel.In order to satisfy the requirement of some automobile panel special shape, there are some automobile panels not only to require its forward punching is also required its side is stretched.
The utility model content
The purpose of the utility model is to provide a kind of automobile panel layback to stretch mould, is exclusively used in the automobile panel that needs forward punching and side direction to stretch.It can be realized the forward punching to automobile panel, can realize that the side stretches simultaneously, can reduce number of molds, and is easy to operate, has saved and has installed and debug man-hour, improves element precision, raises labour productivity, thereby has improved economic benefit.
The technical scheme of the utility model is: it is made up of part of the upper die and part of the lower die, and the part of the upper die is made up of last wedge, drive block, piercing punch, binder core, nitrogen spring; The part of the lower die is by die shoe, down wedge, punching concave die, nitrogen spring, layback stretch that punch, buffering polyamine fat, retracting spring structure, layback are stretched die, the piece of stepping down is formed.
The binder core is controlled by forcing press and nitrogen spring, and provides enough big pressure to realize automobile panel is carried out binder.
Layback is stretched punch and is given and to be linked to each other with nitrogen spring, and the power of lathe slide block is passed to down wedge and the realization side direction stretching to automobile panel through last wedge, and forcing press and nitrogen spring can offer layback and stretch the enough big pressure of punch.
Layback is stretched die and is linked to each other with the piece of stepping down, and drive block is fixed on the upper bolster, and the power source that layback is stretched die is a upper bolster, and promptly upper bolster drives drive block, drive block and passes to layback through the piece of stepping down and stretch die and automobile panel is carried out layback stretch.
Buffering polyamine fat is installed in the both sides of the piece direction of motion of stepping down; And the retracting spring structure, layback is installed below stretching die; Spring in buffering polyamine fat and the retracting spring structure all can provide enough big elastic force; Play the reset response of the piece of stepping down, layback being stretched die, and can prevent that layback from stretching die and producing vibration at the volley.
Layback is stretched punch, layback and is stretched the motion of die, drive block and the piece of stepping down and led by guide plate.
The advantage of the utility model is: 1) the utility model can also stretch to its side direction when automobile panel is carried out the forward punching, and a mold can be accomplished the task that many molds could be accomplished, and has saved die cost, increases economic efficiency; 2) saved the installation and the debug time of mould, improved the production efficiency of automobile panel greatly, increased economic efficiency; 3) broken the automobile panel drawing die and can only realize the pattern that forward stretches, working method is relatively more novel; 4) because automobile panel is realized that simultaneously forward punching and side direction stretch, and have guaranteed the positional precision of punching and side.

The specific embodiment
In conjunction with Fig. 1, Fig. 2 the utility model is further specified, the automobile panel layback is stretched mould, comprises part of the upper die and part of the lower die composition, and the part of the upper die is made up of upper bolster 8, last wedge 9, drive block 18, binder core 6, piercing punch 4; The part of the lower die by die shoe 2, down wedge 10, punching concave die 3, nitrogen spring 11, layback stretch that punch 7, buffering polyamine fat 14, layback are stretched die 16, the piece 17 of stepping down, retracting spring structure form; Binder core 6 links to each other with upper bolster 8 through nitrogen spring 11; Last wedge 9 links to each other with upper bolster 8, and following wedge 10 links to each other with die shoe 2; Punching concave die 3 links to each other with die shoe 2 through key 1; Layback is stretched punch 7 and is linked to each other with following wedge 10 through nitrogen spring 11, and layback is stretched punch 7 and slided on fixing lug boss 13 through guide plate 12; Layback is stretched die 16 and is linked to each other with the piece 17 of stepping down, and the piece 17 of stepping down can slide on die shoe 2 through guide plate 12; Drive block 18 is fixed on the upper bolster 8, and drive block 18 can produce relatively with the piece 17 of stepping down through guide plate 15 and slide; Stretch the front and back of die 16 directions of motion at layback and load onto buffering polyamine fat 14 respectively; Layback stretch die 16 below retracting spring structure 15 is installed; Spring in buffering polyamine fat 14 and the retracting spring structure 15 all can provide enough big elastic force; Both can 16 cushioning effects of offside stretching die, but also offside stretching die 16 plays reset response;
This automobile panel layback is stretched working process of mould: plate is placed on the punching concave die 3 of counterdie, starts forcing press, upper bolster 8 is descending; Driving binder core 6 pushes down plate and carries out the forward punching; It is descending and promote to step down piece 17 to the mould external movement through guide plate 12 to drive drive block 18 simultaneously, and the piece 17 of stepping down drives laybacks and stretches die 16 and move to maximum position, this moment upper bolster 8 also to drive wedge 9 descending; Last wedge 9 drives wedge 10 down; And promote laybacks through nitrogen spring 11 and stretch 7 pairs of plates of punch and carry out side direction and stretch, nitrogen spring 11 can provide enough big pressure, and can guarantee that layback stretches die 16 and stretch punch 7 relative motions simultaneously with layback plate is carried out the side direction stretching; After forward punching and side direction stretching completion; Upper bolster 8 is up, drive binder core 6, go up wedge 9 and drive block 18 up, step down piece 17 the elastic force effect of buffering polyamine fat 14 down with the elastic force effect of retracting spring structure 15 medi-springs under 16 realizations of offside stretching die reset; Layback is stretched punch 7 and is resetted through nitrogen spring 11; At this moment layback is stretched die 16 and is stretched punch 7 simultaneously to the direction motion of leaving mutually with layback, and the operator can take out the forward punching and the side direction stretching of 5, one automobile panels 5 of the good automobile panel of punching press easily and accomplish.
