Fig. 2 is the left view of Fig. 1.
Fig. 3 begins the view of pre-bending product for the present invention.
Fig. 4 is the vertical view of the counterdie among the present invention.
Fig. 5 is in the structural representation of closure state for mould among the present invention.
The structural representation that Fig. 6 finishes for formed product among the present invention.
The specific embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1 ~ Fig. 6, comprise flicking spring 1, bullet screw 2, lower bolster 3, bullet top spring 4, lower bolster 5, roof shell 6, supporting base 7, forming slide 8, die 9, compression leg 10, location-plate 11, punch 12, fixed head 13, upper padding plate 14, cope match-plate pattern 15 etc.
Like Fig. 3, shown in Figure 4, the present invention is a Wedge type bending die in a kind of elasticity folder, comprises patrix and counterdie.
Patrix comprises cope match-plate pattern 15 and is fixed on punch 12 and a pair of compression leg 10 under the cope match-plate pattern 15, and the cross sectional shape of the cross sectional shape of punch 12 and elasticity folder product is complementary, and a pair of compression leg 10 lays respectively at the both sides of punch 12.Cope match-plate pattern can also be equipped with fixed head 13 15 times, and punch 12 and compression leg 10 are fixed on fixed head 13 times.Be provided with upper padding plate 14 between fixed head 13 and the cope match-plate pattern 15.
Counterdie comprises lower bolster 3 and is fixed on a pair of supporting base 7 that is oppositely arranged, a pair of die 9 and a pair of location-plate 11 on the lower bolster 3 successively, can also be provided with lower bolster 5 between lower bolster 3 and a pair of supporting base 7.Location-plate 11 can play the effect of the initial alignment of product, and die 9 can be pre-bent to U-shaped to tablet, and supporting base 7 plays fixed support forming slide 8.
Bottom between a pair of supporting base 7 is provided with roof shell 6, is equipped with between roof shell 6 and the lower bolster 3 and also is provided with the bullet screw 2 that connects roof shell 6 and lower bolster 3 between 4, two bullet tops of spring, two bullet tops spring 4.Roof shell 6 can hold up forming slide 8 through the elastic force of following bullet top spring 4 when not receiving the pressure of patrix compression leg 10, make forming slide 8 keep original state.
A pair of supporting base 7 relative tops are provided with the inclined-plane of symmetry, are sliding combined with pair of molding slide block 8 between two inclined-planes, and pair of molding slide block 8 is positioned on the roof shell 6, is provided with two levels between the pair of molding slide block 8 and flicks spring 1.Forming slide 8 receives the inside and flicks the power of spring 1 and divide right and left when original state, the skid force when downforce that receives patrix compression leg 10 and lateral branch bearing 7 inclined-planes will move down and close up when overcoming the bullet top power of following bullet top spring 4.
Have on a pair of die 9 and a pair of compression leg 10 corresponding through holes, be reserved with between a pair of die 9 and punch 12 corresponding gaps.
Operation principle of the present invention is: through location-plate 11 tablet is located; Through die 9 tablet is curved U-shaped again; The power of utilizing slider of punch to glide then applies a side force through a cover Wedge mechanism of being made up of supporting base 7 and forming slide 8 to product, makes formed product.
The course of work of the present invention is following: the first step is placed on good down tablet on the location-plate 11.Second step, start punch press and carry out punching press, slider of punch glides, and it is as shown in Figure 3 through die 9 blank at first to be curved U-shaped when the punch 12 on the patrix touches tablet, and gets in the middle of the two formation of lots slide blocks 8; Slider of punch continues to glide, and when patrix compression leg 10 touched forming slide 8, forming slide 8 just began to shrink to the center along the inclined-plane of supporting base 7; Forming slide 8 also just is retracted to minimum when slider of punch moves down into down initial point, and the workpiece extrusion modling is as shown in Figure 5, has at this moment also just accomplished the operation that is shaped.At this moment slider of punch bottom out, and moulding slide block 8 also and then gos up under the active force of bullet top spring 4, receives simultaneously in the forming slide 8 middle power that flick spring 1 dividing right and left; Slider of punch continues to go up, and divides right and left along with the rise of forming slide 8, and the punch 12 of patrix has also just broken away from the parcel of forming slide 8, has got back to last initial point, and the intact product of moulding has wrapped on the punch 12, and is as shown in Figure 6.The 3rd step, product is taken off from punch 12, accomplish all processes of a drawing.But the present invention's once-forming elasticity folder product; Reduced operation; Improved production efficiency, simultaneously also reduced the accumulated error of product in forming technology, reduced product in processing, handling process distortion and collide with; Thereby improve the final finished size stability greatly, improved the quality of product; Adopt the present invention can reduce half the device resource and human resources, processing parts is fast, is fit to large batch of part production, is applicable to bend 1mm with interior product.
