Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 4, the present invention mainly comprises up and down just to the upper die and lower die arranged, and patrix comprises upper bolster 1, upper bolster 1 lower end connects upper padding plate 2, upper padding plate 2 is fixed train wheel bridge 4, train wheel bridge 4 clamps upper folded block 3, is fastened on upper bolster 1 by upper folded block 3.
Counterdie comprises die shoe 7, and die shoe 7 upper end connects lower bolster 8, and lower bolster 8 upper end connects lower bolster 9, and in lower bolster 9, symmetrical two roller bearings, 11, two roller bearings 11 that are provided with freely can rotate in respective installation cavity.Be provided with block 23 floating life between two roller bearings 11 of lower bolster 9, floating life, block 23 lower end connected block backing plate 13 of growing floating on water.As shown in Figure 5, roller bearing 11 both sides, 22, two, inner position chamber being provided with circular arc in the middle part of two roller bearings 11 are provided with the outside fix chamber 23 of circular arc, and inner position chamber 22 is for positioning the direction of workpiece bending.Inner position chamber 22 is identical with the opening direction in outside fix chamber 23.The both sides of each roller bearing 11 connect one end of a roller bearing spring 21 respectively, and the other end of roller bearing spring 21 is fixed on die shoe 7 by bearing pin.
Die shoe 7 lower end connects bottom plate 5 by lower cushion block 6, and bottom plate 5 center fixing spring backing plate 15, spring backing plate 15 connects multiple nitrogen spring 14, and multiple nitrogen spring 14 upper end connects block backing plate 13 of growing floating on water.
Described lower bolster 9 is fixed the left and right sides that two blocks, 10, two blocks 10 lay respectively at two roller bearings 11.
Guiding mechanism is provided with between the corner of described upper die and lower die, guiding mechanism comprises four guide pin bushings 16 be fixed on upper bolster 1 four jiaos and four guide pillars 17 be fixed on die shoe 7 four jiaos, four guide pillars 17 are slidably matched with four guide pin bushings 16 respectively, are provided with a return spring 18 between each guide pillar 17 and guide pin bushing 16.In use, guiding mechanism plays guide effect to the motion between upper and lower mould.
Be provided with position-limit mechanism between described upper die and lower die, position-limit mechanism comprises the upper limit position block 19 be fixed on upper bolster 1 and the lower position block 20 be fixed on die shoe 7, and upper limit position block 19 and lower position block about 20 are just to setting.In use, by the distance between the spacing upper and lower mould of position-limit mechanism.
Operation principle of the present invention is: during mould die opening state, needs the product of bending by block jack-up of growing floating on water, now roller bearing inside and outside positioning chamber opening upwards under the pulling force of roller bearing extension spring.When mold is descending, upper folded block contacts with needing the product of bending, completes the action of binder.When patrix continues descending, patrix contacts with the outside fix chamber of roller bearing, promotes roller bearing and rotates around playing axle center, and the two end portions bending of product.Patrix continues descending, and the roller bearing of upper bending and counterdie is killed, and completes bending.After completing bending, patrix is up, and upper folded block moves along with patrix, and the product after block of growing floating on water under the top power of counterdie nitrogen spring heads on bending rises, and bending roller bearing resets under the pulling force of extension spring.
Structure of the present invention is simple, compact, reasonable, and working stability is reliable, ensures that each size after bending reaches requirement; By adjusting the height that mould closes thus the bending angle that conveniently adjustment product is different, expanding the scope of application of one set of die, possessing good versatility, reduce production cost.
