DETAILED DESCRIPTION

[0019] The following will be combined with the Figure 1 - Figure 3 The application will be further described in detail.

[0020] Embodiment one:

[0021] A sign bending device, comprising a base 1, the outer wall of the base 1 is fixedly connected with a support 2, the outer wall of the support 2 is fixedly connected with a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected with a lower pressing seat 4, and the outer wall of the lower pressing seat 4 is bolted with a bending tool 6, which is convenient for bending the metal sign. By starting the hydraulic cylinder 3, the output end of the hydraulic cylinder 3 drives the lower pressing seat 4 to move downward, so that the lower pressing seat 4 drives the bending tool 6 to move downward, and the bending work of the metal sign is completed. The base 1 is fixedly connected with a bending table 7 at the bottom of the bending tool 6, the outer wall of the bending table 7 is provided with a bending groove 12 matched with the bending tool 6, the metal sign is placed on the bending table 7, so that the bending tool 6 moves downward and corresponds to the bending groove 12 below, thereby facilitating the bending of the metal sign. The outer walls of the two sides of the bending table 7 are provided with sliding rails 9, the outer walls of the sliding rails 9 are slidingly connected with positioning blocks 8, the positioning blocks 8 are provided on both sides of the bending table 7, the positioning blocks 8 on both sides are symmetrically adjusted, and the positioning blocks 8 on both sides position the metal signs of different widths. Here, the different widths refer to less than the width range of the bending table 7. The outer wall of the base 1 is provided with an inner groove 14, the outer wall of the inner groove 14 is rotatably connected with a bidirectional screw rod 16, wherein the outer wall of the bidirectional screw rod 16 is provided with a helix angle of twenty degrees, and the thread lifting of the bidirectional screw rod 16 is less than the equivalent friction angle of the helical pair composed of the bidirectional screw rod 16 and the two positioning seats 15, forming self-locking to prevent movement caused by external factors. The outer walls of the two sides of the bidirectional screw rod 16 are threadedly connected with the positioning seats 15. By driving the bidirectional screw rod 16 to rotate, the bidirectional screw rod 16 drives the positioning seats 15 on both sides to move synchronously and oppositely. The positioning seats 15 on both sides can center the metal signs of different lengths. The center positioning of the two positioning blocks 8 ensures that the bending of the metal sign corresponds to the bending groove 12. After positioning, the two positioning seats 15 are moved to the outside synchronously to avoid affecting the positioning of the metal sign and ensure accurate bending.

[0022] The outer walls of the two sides of the bending table 7 are linearly arrayed with a plurality of adjusting holes 11, the outer wall of the positioning block 8 is threadedly connected with a bolt 10, and the bolt 10 is matched with the adjusting hole 11. By providing a plurality of adjusting holes 11 with the same spacing between them, and by slidingly adjusting the two positioning blocks 8, the two positioning blocks 8 are symmetrically adjusted to limit the metal sign. After the two positioning blocks 8 are adjusted, the bolt 10 is rotated to be clamped with the adjusting hole 11, thereby fixing the positioning block 8.

[0023] The positioning seat 15 is in the same plane with the bending table 7, and the positioning seat 15 is in the same plane with the bending table 7, so that the surfaces of the two positioning seats 15 are combined with the surface of the metal plate, thereby facilitating the positioning of the metal signboard.

[0024] The two side inner walls of the support 2 are provided with sliding grooves 5, and the two sides of the pressing seat 4 are slidingly connected with the two sliding grooves 5, so that the sliding connection of the pressing seat 4 and the two sliding grooves 5 facilitates the stability of the movement of the pressing seat 4.

[0025] The side outer wall of the base 1 is fixedly connected with a servo motor 13, and the output shaft of the servo motor 13 is fixedly connected with a bidirectional screw rod 16. The servo motor 13 is started by an external power supply, so that the output shaft of the servo motor 13 drives the bidirectional screw rod 16 to rotate, thereby driving the two positioning seats 15.

[0026] The two side outer walls of the support 2 are fixedly connected with limiting blocks 17, so that the limiting blocks 17 facilitate the limiting of the movement of the two positioning seats 15.

[0027] The implementation principle of the signboard bending device is as follows: first, the metal signboard is placed on the bending table 7, the bolt 10 is separated from the adjusting hole 11 by twisting, so that the fixing of the positioning block 8 is loosened, then the positioning block 8 is moved by sliding, the positioning block 8 is connected with the adjusting hole 11 with the same spacing, the position of the positioning block 8 is adjusted, the positioning block 8 is positioned on both sides of the metal signboard with different widths, when the positioning block 8 is adjusted, the bolt 10 is installed on the positioning block 8, and the adjusting hole 11 corresponding to the adjusted positioning block 8 is connected, the fixing of the positioning block 8 is completed, the servo motor 13 is started by an external power supply switch, the output shaft of the servo motor 13 drives the bidirectional screw rod 16 to rotate, so that the bidirectional screw rod 16 drives the two positioning seats 15 to move, and then the two positioning seats 15 position the metal signboard with different lengths, the metal signboard is positioned by cooperating with the above-mentioned two positioning blocks 8, the bending part of the metal signboard is accurately connected with the bending groove 12, and then the hydraulic cylinder 3 is started, so that the hydraulic cylinder 3 drives the pressing seat 4 to move downward, so that the pressing seat 4 drives the bending tool 6 to bend the metal signboard below.
