[0029] In this embodiment, the convex and concave dies for bending are divided into a plurality of independent concave modules 130 and convex modules 170 according to a single wavy shape of the iron sheet. According to the arrangement form of the wavy shape of the iron sheet to be bent, the concave modules 130 and convex modules 170 of corresponding specifications can be selected for arrangement and combination, and then the arranged concave modules 130 and convex modules 170 are respectively installed in the base 120 below and the mounting seat 160 above, and then the iron sheet is placed on the top of the plurality of concave modules 130, and the mounting seat 160 is driven downward by the first telescopic cylinder 150 (generally a hydraulic cylinder) so that the plurality of convex modules 170 are pressed against the iron sheet, and the iron sheet can be bent into a corresponding wavy shape through the cooperation of the convex surface at the bottom of the convex module 170 and the arc-shaped groove at the top of the concave module 130, which can adapt to the bending of iron sheets with regular or irregular wavy shapes, thereby improving versatility, and there is no need to prefabricate a plurality of integral concave and convex dies, and only a single independent concave module 130 and convex module 170 need to be selected for combination and installation, thereby improving the reuse rate of the mold and reducing the mold cost.

[0030] As an optional embodiment, a first clamping mechanism 180 is provided on the side wall of the base 120 , and a second clamping mechanism 190 is provided on the side wall of the mounting seat 160 . The first clamping mechanism 180 is used to clamp multiple concave modules 130 , and the second clamping mechanism 190 is used to clamp multiple convex modules 170 .

[0031] In this embodiment, when the concave module 130 and the convex module 170 are installed, since the concave modules 130 and the convex modules 170 are arranged in multiple dispersed arrangements, they need to be pressed into one. During the pressing, the multiple concave modules 130 and the convex modules 170 can be pressed respectively by the first pressing mechanism 180 and the second pressing mechanism 190, so that the multiple concave modules 130 and the convex modules 170 are pressed into a whole to ensure that the subsequent iron sheet can be bent into the corresponding wave shape.

[0032] As an optional embodiment, the first clamping mechanism 180 includes a second telescopic cylinder 181 arranged on the side wall of the base 120, and the second telescopic cylinder 181 is connected to a pressure plate 182 located in the accommodating groove, and the pressure plate 182 is used to press the multiple concave modules 130 from the side. The structure of the second clamping mechanism 190 is the same as that of the first clamping mechanism 180.

[0033] In this embodiment, during the clamping operation, the second telescopic cylinder 181 (horizontally arranged) pushes the pressure plate 182 to move horizontally, thereby automatically clamping the multiple concave modules 130 from the side. The clamping is firm and stable and will not loosen. The second clamping mechanism 190 clamps the convex module 170 in the same way, which will not be repeated here.

[0034] As an optional embodiment, a mounting groove 210 for installing the convex module 170 is opened in the mounting seat 160, and a cover plate 220 is hinged on the top of the mounting groove 210. The cover plate 220 is attached to the top surface of the convex module 170, and the other side of the cover plate 220 is detachably connected to the top of the mounting seat 160.

[0035] In this embodiment, during installation, the cover plate 220 is opened, and the selected multiple convex modules 170 are arranged and installed in the installation groove 210, and the multiple convex modules 170 are clamped by the second clamping mechanism 190, and then the cover plate 220 is closed, and the other end of the cover plate 220 is fixed to the top of the mounting seat 160 (can be fixed by screws). The cover plate 220 can be pressed against the top of the convex module 170 to prevent the convex module 170 from sliding upward due to the reaction force during the bending process, thereby ensuring the bending forming effect.

[0036] As an optional embodiment, the mounting groove 210 includes a limiting groove 211 and a through groove 212 connected to the bottom of the limiting groove 211, the width of the limiting groove 211 is greater than the width of the through groove 212, the convex module 170 includes a convex template 171 passing through the through groove 212, the top of the convex template 171 is connected to a limiting strip 172 located in the limiting groove 211, and the width of the limiting strip 172 is greater than the width of the through groove 212, and the limiting strip 172 is in contact with the bottom surface of the cover plate 220.

[0037] In this embodiment, during installation, the male module 170 is installed from the top of the mounting seat 160 into the mounting groove 210. At this time, the male template 171 passes through the limiting groove 211 and extends into the through groove 212, while the limiting strip 172 cannot enter the through groove 212. The limiting strip 172 is installed in the limiting groove 211, thereby hanging the male module 170 in the mounting seat 160 to facilitate the subsequent clamping of the male module 170.

[0038] As an optional embodiment, a movable groove 111 is opened on the workbench 110, and a turntable 230 is movably connected in the movable groove 111. At least two bases 120 distributed in a circular array are arranged on the turntable 230, and any base 120 can be rotated to be directly below the mounting seat 160.

[0039] In this embodiment, multiple bases 120 are installed on a rotatable turntable 230. After the bending of the iron sheet is completed, the turntable 230 is rotated to rotate the base 120 that has completed the bending work to the other side to facilitate the material picking operation, and the base 120 with the iron sheet to be bent is rotated to the bottom of the mounting seat 160, so that the bending operation can be performed at the same time. Through the design of the turntable 230, the synchronous operation of material picking and bending is realized, thereby improving work efficiency.

[0040] As an optional embodiment, the turntable 230 is connected to a driving mechanism 240, and the driving mechanism 240 is used to drive the turntable 230 to rotate a preset angle. The driving mechanism 240 includes a driving motor 241 disposed at the bottom of the workbench 110, and the driving motor 241 is connected to a driving gear 242 located in the movable groove 111, and the driving gear 242 is meshedly connected to a driven gear ring 243 fixedly sleeved on the outer side wall of the turntable 230.

[0041] In this embodiment, when the turntable 230 needs to be rotated, the driving motor 241 (which can be a stepping motor or a servo motor) drives the active gear 242 to rotate, thereby driving the driven gear ring 243 and the turntable 230 to rotate synchronously, thereby realizing automatic rotation control of the turntable 230 with high control accuracy.

[0042] As an optional implementation, a movable shaft 250 is connected to the bottom of the turntable 230. The movable shaft 250 is movably connected to the bottom of the movable groove 111 through a bearing. The movable shaft 250 supports the rotation of the turntable 230 and has low wear.
