The sizes of the mold one, mold two, mold three, and mold four increase from small to large. Pressing blocks are arranged on both sides outside the mold four. A cylinder is arranged above the two pressing blocks, and the output shaft of the cylinder is fixedly connected to the pressing block.

[0008] As a further solution of the utility model, support columns are arranged on the top of the workbench. Axle seats are arranged on both sides at the top of the support columns, and a bidirectional lead screw is movably connected to the axle seats.

[0009] As a further solution of the utility model, two sets of screw sleeves are threadedly connected to the outside of the bidirectional lead screw, and the two sets of screw sleeves are respectively fixedly connected to the two cylinders.

[0022] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1-4As shown in the figure, an arc-shaped metal sheet forming device includes a workbench 1. At the center of the top of the workbench 1, there is a first mold 2. Outside the first mold 2, there are a second mold 3, a third mold 4, and a fourth mold 5. The first mold 2, the second mold 3, the third mold 4, and the fourth mold 5 are all in a semi-circular shape, and the sizes of the first mold 2, the second mold 3, the third mold 4, and the fourth mold 5 increase from small to large. On both sides of the outside of the fourth mold 5, there are bending blocks 13. Above the two groups of bending blocks 13, there is a cylinder 11, and the output shaft of the cylinder 11 is fixedly connected to the bending block 13.

[0024] In this embodiment, support columns 6 are provided on the top of the workbench 1. On both sides of the top of the support columns 6, there are shaft seats, and the shaft seats are movably connected to a bidirectional lead screw 10.

[0025] During use, two groups of cylinders 11 are started simultaneously, and the bending blocks 13 move downward to process the metal plate.

[0026] In this embodiment, two sets of screw sleeves 9 are threadedly connected to the outside of the bidirectional lead screw 10, and the two sets of screw sleeves 9 are respectively fixedly connected to the two groups of cylinders 11.

[0027] When the bidirectional lead screw 10 is rotated, the two sets of screw sleeves 9 will directly approach or move away from each other.

[0028] In this embodiment, an activity groove is provided through the upper and lower parts of the support column 6, and the lower part of the outside of the screw sleeve 9 is located in the activity groove.

[0029] When the bidirectional lead screw 10 rotates, the two sets of screw sleeves 9 will move in the activity groove.

[0030] In this embodiment, a support plate 12 is provided inside the support column 6, and the cylinder 11 is located above the support plate 12.

[0031] The support plate 12 plays a role in supporting the cylinder 11, and a square groove is provided through the support plate 12, so it does not affect the movement of the cylinder 11.

[0032] In this embodiment, sliders 8 are provided at the bottoms of the second mold 3, the third mold 4, and the fourth mold 5. Threaded grooves are provided through the sliders 8 and the workbench 1, and bolts 7 are provided in the threaded grooves.
