[0013] In summary, compared with the prior art, the sheet metal flattening mechanism provided by the present invention for sheet metal processing has the following beneficial effects:

[0014] 1. In the present invention, the servo motor drives the bidirectional screw to rotate, so that the slider slides outward from the inside of the slide, and then drives the flattening roller to flatten the workpiece from the middle to both sides, thereby improving the flattening accuracy and preventing warping. Manual adjustment by staff is required, which improves the flattening efficiency of the entire workpiece.

[0015] 2. In the present invention, an external air jet device is connected through an air nozzle to blow away the dust on the surface of the workpiece to prevent the dust and impurities adhering to the surface of the workpiece from being embedded in the workpiece, thereby affecting the flattening quality of the workpiece;

[0016] 3. In the utility model, the cylinder pushes the workpiece forward through the push plate, and fixes the workpiece in the limit groove to prevent the workpiece from displacement during the flattening process, which affects the processing quality. After flattening, the external pushing force is cancelled, and then the spring automatically pushes the workpiece out through the top plate, releasing the fixation, facilitating removal, and speeding up work efficiency.

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] refer to Figure 1 and Figure 2 A sheet metal flattening mechanism for sheet metal processing includes a base 1, a workpiece 2 is placed on the upper surface of the base 1, and a fixing plate 3 is fixedly installed on the upper surface of one end of the base 1, and a limiting groove 4 corresponding to the workpiece 2 is opened inside the fixing plate 3, the lower surface of the limiting groove 4 is flush with the upper surface of the base 1, and a spring 5 is fixedly installed on the inner surface of the limiting groove 4, and a top plate 6 is fixedly installed on the other end of the spring 5, and the top plate 6 is slidably arranged inside the limiting groove 4.

[0024] Furthermore, when in use, one end of the workpiece 2 is pushed into the limiting groove 4, and the spring 5 is squeezed through the top plate 6 to complete the limiting, fix the workpiece 2, and then the workpiece 2 is flattened. After flattening, the pushing force on the workpiece 2 is cancelled, and then the spring 5 automatically pushes the workpiece 2 out through the top plate 6, which is convenient for removal and speeds up work efficiency.

[0025] refer to Figure 1 A side plate 7 is fixedly installed on the upper surface of one end of the base 1 away from the fixed plate 3, a cylinder 8 is fixedly installed on one side surface of the side plate 7, and an L-shaped push plate 9 is fixedly installed on the output end of the cylinder 8. The corner of the L-shaped push plate 9 corresponds to the side corner of the workpiece 2, so that the workpiece 2 can be stably positioned.

[0026] Furthermore, when in use, the cylinder 8 pushes the workpiece 2 forward through the push plate 9, and fixes the workpiece 2 in the limiting groove 4 to prevent the workpiece 2 from being displaced during the flattening process, which affects the processing quality.

[0027] refer to Figure 1 Two sets of brackets 10 are fixedly installed on the front and rear sides of the base 1. A support plate 11 is fixedly installed on the top of the bracket 10. A hydraulic cylinder 12 is fixedly installed on the upper surface of the support plate 11. The piston rod of the hydraulic cylinder 12 passes through the lower surface of the support plate 11 and slides together, and an installation box 13 is fixedly installed on the bottom end.

[0028] refer to Figure 4 A symmetrical slide groove 14 is provided on the lower surface of the installation box 13 , and a bidirectional screw rod 15 is rotatably installed inside the installation box 13 . A slider 17 that slides inside the slide groove 14 is symmetrically threadedly installed on the surface of the bidirectional screw rod 15 .

[0029] refer to Figure 3 A U-shaped fixing frame 18 is fixedly installed on the lower surface of the slider 17, and a rotating shaft 19 is fixedly installed on the opposite surface of the U-shaped fixing frame 18. A flattening roller 20 is rotatably installed on the surface of the rotating shaft 19. The bottom end of the U-shaped fixing frame 18 is located below the flattening roller 20, which is used to clamp the front and rear sides of the workpiece 2 to further enhance the fixing effect.

[0030] Furthermore, when in use, the hydraulic cylinder 12 drives the mounting box 13 to move downward, so that the flattening roller 20 is located on the upper surface of the workpiece 2, and the U-shaped fixing frame 18 clamps the workpiece 2, and then controls the servo motor 16 to rotate, so that the servo motor 16 drives the bidirectional screw rod 15 to rotate, thereby causing the slider 17 to slide outward inside the slide groove 14, and then drives the flattening roller 20 to flatten the workpiece 2 from the middle to both sides. This is different from the prior art that directly flattens the entire workpiece 2. In this way, the flattening accuracy is not high, the flattening is not thorough, and warping is prone to occur. Manual operation and adjustment by staff are required, which reduces the flattening efficiency of the entire workpiece 2.

[0031] refer to Figure 3 One side of the flattening roller 20 is provided with an air nozzle 24 fixedly mounted on the lower surface of the U-shaped fixing frame 18. The air outlet end of the air nozzle 24 is tilted downward, and the air nozzle 24 is connected to an external jet device to blow away the dust on the surface of the workpiece 2 to prevent the dust and impurities adhered to the surface of the workpiece 2 from being embedded in the workpiece 2, thereby affecting the flattening quality of the workpiece 2.

[0032] refer to Figure 3 A vertical plate 21 is fixedly installed on the lower surface of the middle part of the installation box 13, and a pressure plate 22 is fixedly installed on the lower surface of the vertical plate 21, which is used to flatten the middle part of the workpiece 2 that has not been flattened by the flattening roller 20. Arc grooves 23 corresponding to the flattening roller 20 are opened on both sides of the pressure plate 22, which are used to cooperate with the use of the flattening roller 20 to prevent pressure leakage and improve the flattening quality.
