[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-3 , this embodiment provides a fully servo press-type bending machine, including an upper die pressing mechanism, a lower die pressing mechanism slidably connected to the upper die pressing mechanism, and a rear retaining mechanism slidably connected to the lower die pressing mechanism;

[0028] The upper die pressing mechanism includes an upper template 11, upper guide posts 12 fixedly arranged at both ends of the lower surface of the upper template 11, an upper knife 13 arranged on one side of the lower surface of the upper template 11, a hinge knife 14 hingedly arranged on the upper knife 13, a leaning plate 15 threadedly connected on the other side, and the upper template 11 is connected to a first motor 16;

[0029] The lower die pressing mechanism includes a lower template 21, lower guide posts 22 fixedly arranged at both ends of the lower template 21, the upper guide posts 12 and the lower guide posts 22 are in clearance fit, a stripping plate 23 and a lower knife 24 are arranged on the lower template 21, the stripping plate 23 is matched with the position of the upper knife 13, a slope is arranged on the outer side surface of the lower knife 24, and the slope surface is matched with the inclined surface of the leaning plate 15;

[0030] The rear retaining mechanism includes a top block 41, a sliding assembly 42 detachably connected to the top block 41, and a second motor 44 connected to the sliding assembly 42 through a transmission shaft 43;

[0031] The upper knife 13 can be set on both sides of the upper template 11 according to the width of the plate-shaped material. The hinge knife 14 is hinged to the upper knife 13. When the upper template 11 is lifted, the lower surface of the hinge knife 14 forms a certain angle with the horizontal plane, so that while the upper template 11 is pressed down, the lower surface of the hinge knife 14 contacts the elastic material plate 23 and finally becomes horizontal, playing a role in protecting the plate-shaped material; when the upper knife 13 presses down on the elastic material plate 23, the elastic material plate 23 deforms downward and cooperates with the top block 41 to achieve the bending effect. After the bending is completed, the elastic material plate 23 restores its deformation and pops up the plate-shaped material upward, eliminating the need for manual lifting.

[0032] The inclined support plate 15 is equidistantly arranged on the side of the lower template 12. When the inclined support plate 15 is pressed down, the inclined surface is connected to the outer slope of the lower knife 24, realizing the function of negative angle bending.

[0033] The first motor 16 controls the up and down movement of the upper template 11, and the second motor 44 controls the sliding assembly 42 through the rotating shaft 43. The first motor 16 and the second motor 44 can be linked.

[0034] In this embodiment, a positioning mechanism connected to the lower die mechanism is included. The positioning mechanism includes a positioning base 31 detachably connected to the lower template 21, a positioning slide bar 32 detachably connected to the positioning base 31, a positioning plate 33 slidably connected to the positioning slide bar 32, and a positioning rod 34 detachably connected to the positioning plate 33. The positioning plate 33 drives the positioning rod 34 to slide on the positioning slide bar 32, enabling positioning according to plate-shaped materials of different specifications.

[0035] In this embodiment, the sliding assembly 42 includes a rear retaining slide plate 422 and a rear retaining base 425. The rear retaining slide plate 422 and the rear retaining base 425 are respectively detachably connected to the mutually perpendicular first slide bar 423 and second slide bar 424. A first slider 421 is detachably arranged with the top block 41. The first slider 421 is slidably connected to the first slide bar 423. A second slider 426 is detachably arranged on the lower surface of the rear retaining slide plate 422. The second slider 426 is slidably connected to the second slide bar 424. The power of the second motor 44 drives the first slider 421 and the second slider 426. The first slider 421 drives the top block 41 to move in a direction parallel to the upper template 11, and the second slider 426 drives the rear retaining slide plate 422 to move in a direction parallel to the transmission shaft 43, thereby achieving precise positioning for multiple bending effects.

[0036] In this embodiment, a strip-shaped chute 111 matching the upper knife 13 is arranged on the upper template 11. A plurality of upper die holes 112 are arranged on the side surface of the upper template 11 close to the upper knife 13. The upper knife 13 can slide out or slide into one side of the strip-shaped chute 111. After sliding in, the upper knife 13 is fixed to the upper template 11 with a threaded bolt, facilitating the replacement of different upper knives 13 according to different bending requirements.

[0037] In this embodiment, a lower template adjusting block 25 is detachably arranged on one side of the lower template 21 close to the positioning mechanism. The adjusting block 25 adjusts the gap of the lower die cutter according to the thickness of the plate-shaped material by using the tightness of the bolts.

[0038] In this embodiment, a positioning connecting piece 331 is arranged on the side surface of the positioning plate 33 away from the lower template 21. The positioning connecting piece 331 is bolted to the positioning base 31. After the position of the positioning rod 34 is determined, the connecting piece 331 is bolted to the positioning base 31 to fix the positioning plate 33 and the positioning rod 34. The plate-shaped material can be accurately positioned on the positioning plate 33 and is not easy to slide during the bending process, improving the bending accuracy and success rate.

[0039] In this embodiment, a plurality of precision ball bearings 221 are arranged on the lower guide post 22 to achieve the sliding fit between the upper template 11 and the lower template 21.

[0040] In this embodiment, a precision nitrogen spring is arranged under the material ejecting plate 23, which has a small volume, a large elastic force and a long service life.

[0041] In this embodiment, it further includes a control board 6. The control board 6 is connected to the first motor 16 through a connecting rod 5, and the control board 6 can control the first motor 16 and the second motor 44 simultaneously.

[0042] During use, the operator first sets the bending parameters and the number of bending steps on the control panel 6 according to the bending requirements of the plate-shaped material. According to the set parameters of the first step, the second motor 44 is started. The second motor 44 drives the first slider 421 and the second slider 426 through the rotating shaft 43. The first slider 421 and the second slider 426 drive and slide on the first slide bar 423 and the second slide bar 424, driving the top block 41 to an appropriate position. According to the thickness of the plate-shaped material, the tightness of the bolts of the lower template adjustment block 25 is adjusted, the position of the positioning plate 33 is adjusted, and the positioning plate 33 is fixed on the positioning base 31 with bolts. The operator places the plate-shaped material on the positioning plate 33, places the protruding part to be bent between the two top blocks 41, places the bending line at the position flush with the end of the top block 41, starts the first motor 16, and presses down the upper template 11. The upper guide post 12 and the lower guide post 22 are slidably matched. The upper template 11 drives the upper knife 13 and the hinge knife 14 to move downward. When the hinge knife 14 touches the plate-shaped material, the end of the hinge knife 14 moves upward until the hinge knife 14 is parallel to the horizontal plane. At this time, the upper knife 13 touches the plate-shaped material. As the upper template 11 continues to press down, the blanking plate 23 deforms downward. The upper knife 13 and the lower knife 24 cooperate to bend the plate-shaped material. After the first step of bending is completed, the blanking plate 23 restores its deformation and ejects the plate-shaped material. The second motor starts to perform the second step of bending operation. The process of the second step of bending operation is the same as that of the first step, and so on until the bending is completed. When it is necessary to replace the upper knife 13, loosen the bolts on the upper die hole 112, slide the upper knife 13 out of the strip-shaped chute 111, slide the new upper knife into the strip-shaped chute 111, and tighten the bolts on the upper die hole 112.

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
