Detailed description of the invention
As depicted in figs. 1 and 2, the one-time formed diel of a kind of folding negative angle, comprise upper die and lower die, described patrix comprises the upper bolster 1 of locating setting from top to bottom, upper padding plate 2 and cope match-plate pattern 3, described counterdie comprises the die shoe 4 of locating setting from bottom to top, lower bolster 5 and lower de-plate 6, between described lower de-plate and described lower bolster, there is elastic space, the side of described cope match-plate pattern is provided with slide block 7, described slide block side and described cope match-plate pattern side are slidably connected, between described slide block and described upper padding plate, there is elastic space, described slide block opposite side shape and the negative angle mating shapes that negative angle product need be rolled over, described lower bolster is provided with elastic body, described elastic body is positioned at described lower de-plate side, need roll over a negative angle product part to be located between described cope match-plate pattern and described lower de-plate, a part is located on described elastic body, and described elastic body elasticity can compress the side of described lower de-plate.In said structure, by arranging the slide block that relative patrix can slide on patrix, by consistent for the negative angle shape that the profile design Cheng Yuxu of the side of slide block rolls over negative angle product; And coordinate the elastic force mechanism that counterdie is arranged, the one-shot forming of folding negative angle can be realized, effectively reduce the technique process of folding negative angle, enhance productivity, reduce the production cost of product.
Preferably, described elastic body comprises fixed block 11 and roller bearing bearing 12, described fixed block is fixed on described lower bolster, described roller bearing bearing is between described fixed block and described lower de-plate, the first back-moving spring 14 is provided with between described roller bearing bearing and described fixed block, roller bearing 13 is provided with between described roller bearing bearing and described lower de-plate, described roller bearing circumference rotational positioning is in described roller bearing bearing, described first back-moving spring one end is positioned in described fixed block, described first back-moving spring other end elasticity compresses described roller bearing bearing, the described roller bearing side elasticity be fixed in described roller bearing bearing is made to compress described lower de-plate.Like this, during die sinking, roller bearing elasticity first time de-plate, during mold closing, because lower de-plate is descending with cope match-plate pattern, elasticity compresses and needs bending product by roller bearing, and the position be located on fixed block is adjacent to slide block, thus the negative angle of bending formation and slide block mating shapes.
Preferably, described slide block opposite side shape with the structure of the negative angle mating shapes need rolling over negative angle product is: described slide block has the first supporting surface 8 and the second supporting surface 9 in negative angle shape, forms continuous print folding surface 10 between described first supporting surface and described second supporting surface.As a kind of preferred embodiment, the present invention is specially adapted to roll over the bending of negative angle product and forms the negative angle with folding surface.
Preferably, the structure between described lower de-plate and described lower bolster with elastic space is: be provided with the second back-moving spring 15 between described lower de-plate and described lower bolster, described second back-moving spring one end is positioned in described die shoe, and the described second back-moving spring other end compresses the bottom of described lower de-plate through described lower bolster elasticity.The function between lower de-plate and lower bolster with elastic space can be realized by said structure, lower de-plate is resetted when die sinking.
Preferably, the structure between described slide block and described upper padding plate with elastic space is: be provided with jigger pin 16 in described upper padding plate, described jigger pin one end is provided with stopper 17, the 3rd back-moving spring 18 is provided with in described upper bolster, described 3rd back-moving spring one end is positioned in described upper bolster, described 3rd back-moving spring other end elasticity compresses described jigger pin one end, make described stopper stop in described upper padding plate, the other end elasticity of described jigger pin is made to compress described slide block, and make the slip of described slide block relatively described cope match-plate pattern exceed described cope match-plate pattern certain distance.Like this, during mold closing, cope match-plate pattern and lower de-plate closing, the relative cope match-plate pattern of part that slide block exceeds cope match-plate pattern starts to slide, slide block starts to extrude jigger pin and compresses the 3rd back-moving spring, during die sinking, under the restoring force effect of the 3rd back-moving spring, the bottom of slide block exceeds certain distance bottom cope match-plate pattern, has been conducive to de-material.
The invention provides a kind of operation principle of rolling over the one-time formed diel of negative angle as follows: before bending, see Fig. 3, slide block and cope match-plate pattern are positioned at the top of lower de-plate, slide block is positioned at the side of cope match-plate pattern and relative cope match-plate pattern slip exceeds cope match-plate pattern certain distance, first back-moving spring elasticity compresses roller bearing bearing, the side elasticity being positioned the roller bearing in roller bearing bearing is made to compress the corresponding side of lower de-plate, lower have elastic space between de-plate and lower bolster, this elastic space makes the upper surface of lower de-plate concordant with the upper surface of roller bearing bearing, negative angle product need be rolled over for supporting, negative angle product part positioning supports need be rolled in the upper surface of lower de-plate, part positioning supports is in the upper surface of roller bearing bearing.During bending, cope match-plate pattern moves downward, and need roll over negative angle product be positioned at part on lower de-plate until push down, now, the relative cope match-plate pattern of slide block slides, and compresses the 3rd back-moving spring, see Fig. 4.Cope match-plate pattern continues descending, negative angle product need be rolled over and lower de-plate is thereupon descending under the driving of cope match-plate pattern, now, roller bearing rotates relative to roller bearing bearing, specifically can be designed to rotate clockwise, the first back-moving spring starts to be compressed, and the second back-moving spring between lower de-plate and lower bolster starts to compress, start to roll over an angle of 90 degrees, see Fig. 5; Cope match-plate pattern continues descending, negative angle product need be rolled over and lower de-plate is also thereupon descending under the driving of patrix, now, owing to being negative angle between the first supporting surface of slide block and the second supporting surface, descending along with cope match-plate pattern, roller bearing is under the effect of the restoring force of the first back-moving spring, elasticity compresses need roll over negative angle product, make it be adjacent to the first supporting surface, negative angle product need be rolled over and be bent into negative angle with the folding surface of slide block and negative angle mating shapes, see Fig. 6; Die sinking after bending, under the effect of the restoring force of the first back-moving spring, the second back-moving spring and the 3rd back-moving spring, roller bearing, lower de-plate and slide block reset to original state, see Fig. 7.
Above embodiment is with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art by carrying out amendment on various forms or change to above-described embodiment, but when not deviating from essence of the present invention, drops within protection scope of the present invention.
