[0026] Embodiment

[0027] In order to solve the problems existing in the prior art that the products after die cutting need to be taken to the bending die for unilateral bending, refer to Figure 1 As shown, the present application discloses an automatic bending device for special-shaped products, which is detachably installed on a round knife machine table. It is characterized in that it includes a cross bar 10 detachably installed on the round knife machine table;

[0028] Two support assemblies 20 are detachably fixed on the cross bar 10, and a connecting plate 30 is detachably fixed at the bottom of the two support assemblies 20;

[0029] A bottom plate 40 is fixed above the connecting plate 30, a backing plate 50 perpendicular to it is fixed on the bottom plate 40, an L-shaped upper die 60 is detachably arranged on one side of the backing plate 50, and an L-shaped lower die 70 is connected along its direction above the bottom plate 40 corresponding to the discharging side of the L-shaped upper die 60. A gap for the material tape to pass through is formed between the horizontal part of the L-shaped upper die 60 and the horizontal part of the L-shaped lower die 70. Specifically, the width of the horizontal part of the L-shaped upper die 60 is greater than the width of the horizontal part of the L-shaped lower die 70. After the unilateral side of the material tape passes between the L-shaped upper die 60 and the L-shaped lower die 70, it will be squeezed and bent;

[0030] When the material tape moves on the bottom plate 40, its unilateral side will pass between the L-shaped upper die 60 and the L-shaped lower die 70. During this process, due to the height difference between the horizontal part of the L-shaped lower die 70 and the bottom plate 40, when the L-shaped upper die 60 and the L-shaped lower die 70 squeeze the material tape, the unilateral side of the material tape will form a bend.

[0031] For the convenience of installation with a circular knife machine, the present application has first waist-shaped holes 11 opened at both ends of the cross bar 10 for a first bolt to pass through and be fixed to the circular knife machine. As for how to install it with the circular knife machine through the first bolt (not marked in the present application), it is not the content claimed in the present application and will not be elaborated here.

[0032] In an embodiment of the present application, both support assemblies 20 include vertical rods 21, upper fixing blocks 22, and lower fixing blocks 23;

[0033] A transverse groove (not marked in the present application) and a first vertical groove (not marked in the present application) are opened inside the upper fixing block 22, and a second vertical groove (not marked in the present application) corresponding to the first vertical groove is opened inside the lower fixing block 23;

[0034] A first tensioning groove 221 communicating with the transverse groove and a second tensioning groove 222 communicating with the first vertical groove are opened on the upper fixing block 22, and a third tensioning groove 231 communicating with the second vertical groove is opened on the lower fixing block 23;

[0035] The cross bar 10 passes through the two transverse grooves of the two upper fixing blocks 22 and extends outwards. After the cross bar 10 is inserted, second bolts 223 are respectively screwed into the two first tensioning grooves 221 corresponding to the two upper fixing blocks 22;

[0036] The vertical rod 21 of each support assembly 20 passes through the first vertical groove of the upper fixing block 22 and is inserted into the second vertical groove of the lower fixing block 23. After the vertical rod 21 is inserted, third bolts 224 are screwed into the corresponding second tensioning grooves 222 of the two lower fixing blocks 23, and fourth bolts 232 are respectively screwed into the corresponding third tensioning grooves 231 of the two lower fixing blocks 23;

[0037] Second waist-shaped holes 233 are respectively opened on the two lower fixing blocks 23, and fifth bolts 234 are screwed into each second waist-shaped hole 233 to be fixed to the bottom plate 40.

[0038] In the specific installation process, first insert the transverse bar into the transverse grooves of the two upper fixing blocks 22 and fix it to the two upper fixing blocks 22 by screwing second bolts 223 into the two first tensioning grooves 221. Then, insert each vertical rod 21 into the first vertical groove of the upper fixing block 22 and the second vertical groove of the lower fixing block 23 respectively, and fix each vertical rod 21 to the upper and lower fixing blocks 23 by screwing third bolts 224 into the second tensioning grooves 222 and fourth bolts 232 into the third tensioning grooves 231. After that, screw fifth bolts 234 into the two second waist-shaped holes 233 of the two lower fixing blocks 23 respectively to fix them to the bottom plate 40. Finally, fix it to the circular knife machine by screwing first bolts into the two first waist-shaped holes 11 of the transverse bar.

[0039] In order to facilitate the quick disassembly and assembly of the L-shaped upper die 60 and the backing plate 50, in this application, at least two sixth bolts 80 are used to fix between the vertical part of the L-shaped upper die 60 and the backing plate 50.

[0040] In addition to the above structure, in this application, a handle part 61 extending outward from the top of the L-shaped upper die toward the backing plate 50 is formed. During the specific installation process, an operator can grasp this handle part 61.
