[0002] During the processing of server racks, the metal plates of the racks need to be bent. Currently, the main processing method is to place the metal plates on a bending machine for stamping and bending. However, the metal plates placed outside the bending machine need to be supported during the bending process to prevent the weight of the metal plates from affecting the bending quality. Therefore, there is an urgent need to propose a sheet metal bending device to solve this problem. Utility Model Content

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A sheet metal bending device includes a support mechanism, which includes a support platform. A support beam is fixed to the rear side of the upper end of the support platform. A bending mechanism is mounted on the support beam. A flipping component is mounted on the support platform that flips along with the cabinet panel when the bending mechanism bends it downwards. The flipping component provides limiting support for the cabinet panel. An clearance groove is provided on the upper surface of the support platform. A countersunk platform is provided on both sides of the clearance groove. The flipping component is respectively mounted on both sides of the clearance groove. The flipping component includes a rotating shaft mounted on the support platform. A placement platform is fixed on the rotating shaft. A pressing component is mounted on the placement platform. A limiting component for limiting the cabinet panel is mounted on the placement platform. A gear is mounted on the rear side of the rotating shaft. The bending mechanism includes a hydraulic column and a guide rod mounted on the support beam. A pressure head is provided at the lower end of the hydraulic column and the guide rod. A double-sided rack is fixed to the rear side of the pressure head. The double-sided rack meshes with the gear.

[0006] Further configuration: The holding assembly includes a bracket fixed on the placement platform. The bracket is open near the bending mechanism. Limiting posts are vertically arranged at intervals on the bracket. A pressure roller is provided at the lower end of the limiting post. A spring is sleeved on the outer diameter of the limiting post above the pressure roller.

[0007] Further design: The limiting post and the bracket are slidably connected.

[0008] Further configuration: The limiting assembly includes a longitudinal limiting plate fixed to the rear side of the bracket, and an adjusting screw and a sliding column set on the side of the bracket.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a sheet metal bending device includes a support mechanism, which includes a support platform 1. A support beam 13 is fixed to the rear side of the upper end of the support platform 1. A bending mechanism is provided on the support beam 13. A flipping component is provided on the support platform 1, which flips along with the cabinet panel when the bending mechanism bends the cabinet panel downwards. The flipping component provides limiting support for the cabinet panel.

[0025] In this embodiment: an clearance groove 11 is provided on the upper surface of the support platform 1, and recessed platforms 12 are provided on both sides of the clearance groove 11. The flipping components are respectively provided on both sides of the clearance groove 11. The flipping components include a rotating shaft 21 provided on the support platform 1, a placement platform 22 fixed on the rotating shaft 21, a pressing component provided on the placement platform 22, and a limiting component for limiting the cabinet panel on the placement platform 22. A gear 27 is installed on the rear side of the rotating shaft 21. The rotating shaft 21 is rotatably connected to the support platform 1, and the horizontal plane of the placement platform 22 is flush with the horizontal plane of the support platform 1. The pressing assembly includes a bracket 23 fixed on the placement platform 22. The bracket 23 is open near the bending mechanism. Limiting posts 24 are vertically arranged at intervals on the bracket 23. A pressure roller 25 is provided at the lower end of the limiting post 24. A spring 26 is sleeved on the outer diameter of the limiting post 24 above the pressure roller 25. The limiting post 24 is slidably connected to the bracket 23. When the cabinet panel is pushed backward from the front of the placement platform 22, the pressure roller 25 moves downward along the limiting post 24 under the push of the spring 26, so that the pressure roller 25 presses the cabinet panel to ensure the stability of the cabinet panel during bending. After the limiting assembly limits its position, when the bending mechanism applies downward pressure, it drives the gear 27 to rotate, so that the gear 27 drives the rotating shaft 21 and the placement platform 22 to rotate upward as a whole, providing simultaneous support on both sides of the bent cabinet panel and ensuring the bending effect of the cabinet panel.

[0026] The limiting assembly includes a longitudinal limiting plate 44 fixed to the rear side of the bracket 23, and an adjusting screw 42 and a sliding column 43 disposed on the side of the bracket 23. A transverse limiting plate 41 is disposed at one end of the adjusting screw 42 and the sliding column 43, which is located under the bracket 23. A handwheel is disposed at the other end of the adjusting screw 42. The adjusting screw 42 is rotatably connected to the bracket 23, the sliding column 43 is slidably connected to the bracket 23, and the adjusting screw 42 is rotatably connected to the transverse limiting plate 41. By manually rotating the adjusting screws 42 on both sides, the transverse limiting plate 41 is moved under the support of the adjusting screws 42 and the sliding column 43, adjusting the transverse limiting plates 41 on both sides to a suitable distance position relative to the pressure head 33, thereby limiting the two sides of the cabinet panel. The longitudinal limiting plate 44 aligns and limits the rear side of the cabinet panel, ensuring the stability of the cabinet panel placement position.

[0027] In this embodiment, the bending mechanism includes a hydraulic column 31 and a guide rod 32 mounted on the support beam 13. A pressure head 33 is mounted at the lower end of the hydraulic column 31 and the guide rod 32. A double-sided rack 34 is fixed to the rear side of the pressure head 33. The double-sided rack 34 meshes with a gear 27. The guide rod 32 is slidably connected to the support beam 13. The extension of the hydraulic column 31 pushes the pressure head 33 and the double-sided rack 34 to move downward under the limit of the guide rod 32, providing downward pressure for bending the cabinet panel. The hydraulic column 31 is connected to a hydraulic oil circuit and control components provided by a hydraulic pump station. The hydraulic pump station and control components are conventional technologies existing in the art and will not be described in detail here.

[0028] The working principle and usage process of this utility model are as follows: The cabinet panel is pushed backward from the front of the placement platform 22 to align with the longitudinal limiting plate 44. The adjusting screws 42 on both sides are rotated to move the transverse limiting plate 41 under the support of the adjusting screws 42 and the sliding column 43. The transverse limiting plates 41 on both sides are adjusted to a suitable distance position relative to the pressure head 33 to limit the two sides of the cabinet panel. The pressure roller 25 moves downward along the limiting column 24 under the push of the spring 26 to press the cabinet panel. Then, the hydraulic column 31 extends to push the pressure head 33 and the double-sided rack 34 downward under the limit of the guide rod 32. When the pressure head 33 contacts the cabinet panel, the double-sided rack 34 at the rear end of the pressure head 33 meshes with the gear 27 on the rotating shaft 21. As the pressure head 33 continues to press down on the cabinet panel, the gear 27 drives the rotating shaft 21 and the placement platform 22 to rotate upward as a whole, providing simultaneous support to both sides of the bent cabinet panel and ensuring the bending effect of the cabinet panel.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
