Description

Technical Field

[0001] This utility model relates to the field of distribution box manufacturing technology, and in particular to a distribution box plate bending device. Background Technology

[0002] A distribution box is a central circuit distribution box for all users' electricity needs. It is a small power distribution device installed at the user end to control multiple power sources. The main materials used in the construction of distribution boxes are metal beams and metal plates. Before the metal plates are covered onto the outside of the beam frame, they need to be bent. Currently, when bending the metal plates, they need to be supported to prevent the bending effect from being affected by gravity, thus resulting in a large amount of processing labor and increasing the burden on operators. Utility Model Content

[0003] The purpose of this utility model is to provide a bending device for distribution box panels in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions: A bending device for a distribution box panel includes a support mechanism, which includes a workbench with a crossbeam and a bending mechanism mounted on the crossbeam. An auxiliary mechanism for supporting the bent metal plate is connected to the lower side of the bending mechanism, and the auxiliary mechanism is distributed on both sides of the bending mechanism. A recessed platform is provided on both sides of the bending mechanism on the workbench, and a clearance groove is provided below the bending mechanism. The bending mechanism includes a hydraulic telescopic cylinder fixed to the crossbeam, with a mounting frame fixed to the lower end of the hydraulic telescopic cylinder. A pressure head is mounted on the lower side of the mounting frame. The auxiliary mechanism includes a support plate mounted on the recessed platform, with support shafts fixed at both ends of the support plate near the bending mechanism. Gears are fixed at both ends of the support shafts, and a semi-rack is provided below the gears. A sliding groove is provided on the workbench opposite to the semi-rack, and a connecting rod connected to the mounting frame is provided on the side wall of the semi-rack.

[0005] Further settings: The adjacent parts of the semi-toothed rack are set to tooth shape, and the side furthest away is set to toothless shape.

[0006] Further setting: The number of teeth on the half-rack is greater than half the number of teeth on the gear.

[0007] Further configuration: the half rack is slidably connected to the slide groove, and the connecting rod is rotatably connected to the half rack and the mounting bracket via a pin.

[0008] Further configuration: The support shaft is rotatably connected to the worktable, and the upper surface of the support plate in a horizontal state is flush with the upper surface of the worktable.

[0009] Further setting: The longitudinal length of the pressure head is greater than the longitudinal length of the support plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the bending mechanism applies downward pressure, the connecting rod pushes the half rack to move to both sides. When the pressure head contacts the metal plate, the teeth on the half rack mesh with the gear. The half rack continues to move and mesh with the gear, causing the gear to drive the support shaft and support plate to rotate upward. This supports both sides of the metal plate that has been bent by the pressure head, improving the quality and effect of bending the metal plate and reducing the workload of operators.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-4 As shown, a distribution box panel bending device includes a support mechanism, which includes a workbench 11, a crossbeam 15 on the workbench 11, and a bending mechanism on the crossbeam 15. An auxiliary mechanism for supporting the bent metal plate is connected to the lower side of the bending mechanism, and the auxiliary mechanism is distributed on both sides of the bending mechanism. The workbench 11 has recessed platforms 13 on both sides of the bending mechanism, and a clearance groove 12 is provided on the lower side of the bending mechanism. In this embodiment: the bending mechanism includes a hydraulic telescopic cylinder 21 fixed on the crossbeam 15. A mounting frame 22 is fixed to the lower end of the hydraulic telescopic cylinder 21. A pressure head 23 is mounted on the lower side of the mounting frame 22. A hydraulic pump station is connected to the hydraulic telescopic cylinder 21 through a hydraulic oil circuit to control the telescopic movement of the hydraulic telescopic cylinder 21. This content is prior art known to those skilled in the art and will not be described in detail here. The telescopic movement of the hydraulic telescopic cylinder 21 drives the pressure head 23 on the lower side of the mounting frame 22 to move as a whole.

[0017] In this embodiment: the auxiliary mechanism includes a support plate 31 set on the sink 13, a support shaft 32 fixed at both ends of the support plate 31 near the bending mechanism, a gear 33 fixed at both ends of the support shaft 32, a half rack 34 set on the lower side of the gear 33, a slide groove 14 set on the worktable 11 opposite to the half rack 34, and a connecting rod 35 connected to the mounting frame 22 set on the side wall of the half rack 34. The adjacent parts of the half-rack 34 are toothed, while the side furthest away is toothless. The number of teeth on the half-rack 34 is greater than half the number of teeth on the gear 33. The half-rack 34 is slidably connected to the slide groove 14, and the connecting rod 35 is rotatably connected to the half-rack 34 and the mounting bracket 22 via a pin. The support shaft 32 is rotatably connected to the worktable 11, and the upper end face of the support plate 31 in a horizontal state is flush with the upper end face of the worktable 11 to ensure the stability of the metal plate. The longitudinal length of the pressure head 23 is greater than the longitudinal length of the support plate 31. When the bending mechanism applies downward pressure, the connecting rod 35 pushes the half-rack 34 to move to both sides. When the pressure head 23 contacts the metal plate, the teeth on the half-rack 34 mesh with the gear 33. The half-rack 34 continues to move and mesh with the gear 33, causing the gear 33 to drive the support shaft 32 and the support plate 31 to rotate upward, supporting both sides of the metal plate that has been bent by the pressure head 23.

[0018] The working principle and usage process of this utility model are as follows: A metal plate is placed on a support plate 31, with the bending part positioned below the pressure head 23. The extension of the hydraulic telescopic cylinder 21 pushes the mounting frame 22 and the pressure head 23 downward as a whole. The mounting frame 22 pushes the semi-rack 34 to move to both sides via the connecting rod 35. When the pressure head 23 contacts the metal plate, the teeth on the semi-rack 34 mesh with the gear 33. As the pressure head 23 continues to move downward, the movement of the semi-rack 34 meshes with the gear 33, causing the gear 33 to drive the support shaft 32 and the support plate 31 to rotate upward. This supports both sides of the metal plate after it has been bent by the pressure head 23, improving the bending effect of the metal plate.

[0019] 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.
