Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A high-precision sheet metal arc bending device includes a worktable 1, an installation groove 101 is provided in the middle of the upper surface of the worktable 1, a lower mold base 5 is provided on the upper surface of the worktable 1 through the installation groove 101, a gantry 2 is provided on both sides of the upper surface of the worktable 1, and a bending mechanism 3 is provided in the middle between the two gantry 2.

[0023] A first baffle 6 is provided on one side of the upper surface of the workbench 1 and inside the gantry 2. A second baffle 601 is provided on the side of the workbench 1 away from the first baffle 6. Both ends of the first baffle 6 and the second baffle 601 are provided with strip-shaped sliding holes 602.

[0024] Position adjustment components 7 are provided on the first baffle 6 and the second baffle 601 through the strip-shaped sliding holes 602. The position adjustment components 7 include limiting plates 701. There are two limiting plates 701, which are respectively located on both sides of the lower mold base 5.

[0025] The bending mechanism 3 includes a top seat 301, a hydraulic cylinder 302, and a forming upper die 303. The top seat 301 is located in the middle between the two masts 2. The hydraulic cylinder 302 is located at the center of the lower surface of the top seat 301. A piston rod is installed inside the hydraulic cylinder 302. The forming upper die 303 is located at the lower end of the piston rod of the hydraulic cylinder 302. The masts 2 facilitate the installation of the bending mechanism 3. The hydraulic cylinder 302 can effectively drive the forming upper die 303 to move up and down. When the forming upper die 303 moves down, it can cooperate with the lower die seat 5 to perform bending operations on the metal sheet.

[0026] The position adjustment component 7 also includes an adjusting screw 702, a handle 703, and a limiting slide rod 704. The adjusting screw 702 is threadedly connected to the first baffle 6, one end of the adjusting screw 702 is rotatably connected to the limiting plate 701, and the end of the adjusting screw 702 away from the limiting plate 701 passes through the first baffle 6 and is connected to the handle 703. The limiting slide rod 704 is slidably connected to the second baffle 601, one end of the limiting slide rod 704 is connected to the limiting plate 701, and the end of the limiting slide rod 704 away from the limiting plate 701 passes through the second baffle 601 and is provided with a limiting plate. By rotating the handle 703, the adjusting screw 702 can be effectively driven to rotate synchronously and move back and forth. During the back and forth movement of the adjusting screw 702, a limiting plate 701 connected to it can be driven to move synchronously back and forth.

[0027] Among them, the two limiting plates 701 are opposite to each other, and both ends are rotatably connected to push-pull rods 705 through connecting shafts. The end of the push-pull rod 705 away from the limiting plate 701 passes through the strip-shaped sliding hole 602 and is provided with a vertical connecting rod 706. A cross connecting rod 707 is provided on the lower surface of the worktable 1. A positioning shaft 708 is provided at the center of the cross connecting rod 707 through a shaft hole. The upper end of the positioning shaft 708 is connected to the worktable 1. The four corners of the cross connecting rod 707 are rotatably connected to the vertical connecting rod 706 through mounting holes. When the metal plate is placed on the upper surface of the lower mold base 5, and the rotation... When the handle 703 pushes a limiting plate 701 connected to it towards the lower mold base 5 via the adjusting screw 702, the two push-pull rods 705 on the back of the limiting plate 701 move closer to each other at the ends away from the limiting plate 701, causing the cross link 707 to fold. Thus, the other limiting plate 701 will move towards the lower mold base 5 synchronously under the pushing action of its back push-pull rod 705. The two limiting plates 701 move synchronously and move closer to each other, which can automatically adjust the position of the metal sheet on the lower mold base 5, ensuring its accurate position. The operation is simple and saves time and effort.

[0028] See Figure 1 and Figure 3 The upper surface of the mounting groove 101 has threaded holes on both sides, and the lower ends of both sides of the lower mold base 5 are provided with fixing edges. The fixing edges of the lower mold base 5 are provided with fixing screws that cooperate with the threaded holes.

[0029] Support frames 4 are provided at both ends of the lower surface of the workbench 1.

[0030] By setting the mounting groove 101 and the threaded hole, it is easy to install and fix the lower mold base 5, ensuring the stability of the lower mold base 5. By setting the support frame 4, it can be effectively used to support the air worktable 1 and ensure the stability of the worktable 1.

[0031] Working principle: When a metal sheet is placed on the upper surface of the lower mold base 5 from the side of the workbench 1 and between the two gantry frames 2, the handle 703 is turned and the adjusting screw 702 pushes a limiting plate 701 connected to it closer to the lower mold base 5. At the same time, the two push-pull rods 705 on the back of the limiting plate 701 move closer to each other, causing the cross link 707 to fold. Thus, the other limiting plate 701 moves closer to the lower mold base 5 synchronously under the pushing action of the push-pull rod 705 on its back. The two limiting plates 701 move synchronously and move closer to each other, which can automatically adjust the position of the metal sheet on the lower mold base 5, ensuring its accurate position. The operation is simple and saves time and effort.

[0032] Furthermore, by setting up the gantry 2, it is easy to install the bending mechanism 3. The hydraulic cylinder 302 can effectively drive the upper forming die 303 to move up and down. When the upper forming die 303 moves down, it can cooperate with the lower die base 5 to perform bending operations on the metal sheet.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
