Description

Technical Field

[0001] The utility model relates to the technical field of plate bending equipment, in particular to a metal plate bending mechanism. Background Art

[0002] Sheet metal bending machines are mainly used to bend and fold sheet metal to form specific shapes and structures. It has a wide range of applications in manufacturing, construction, metal processing and other fields, and is an important tool for automating sheet metal processing. Stress is formed on the sheet metal by applying pressure or torque. When the applied force exceeds the elastic limit of the metal material, the metal material will undergo plastic deformation, that is, bending. In the operation of the bending machine, the sheet metal is usually placed on the workbench first, and the position of the sheet is fixed using a clamp or positioning device. Then, the upper and lower dies are used to apply force to the sheet metal to bend it. The gap between the upper and lower dies determines the bending angle and bending radius of the sheet metal.

[0003] When a traditional bending machine presses a groove in the middle of a plate, the two sides of the metal plate will move toward the bending groove and gather together, wear marks will be generated on the metal plate and the supporting surface, and the two sides of the metal plate may warp up simultaneously, making it difficult to obtain the desired product shape, resulting in failure of the bending process. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] Example

[0025] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, this embodiment is a metal plate bending mechanism, comprising a bottom plate 1, a bending slot seat 2 arranged on the bottom plate 1, movable support platforms 3 are respectively arranged on both sides of the bending slot seat 2, and the upper surface of the movable support platform 3 is flush with the top surface of the bending slot seat 2, and a gap is provided between the movable support platform 3 and the bending slot seat 2; a pressure head 4, which is arranged above the bending slot seat 2 and is adapted to the bending slot seat 2, and the upper end of the pressure head 4 is connected to a hydraulic cylinder 5; a limiting pressure plate 6, which is respectively arranged on both sides of the movable support platform 3, and the limiting pressure plate 6 is slidably connected to the bottom plate 1. On the plate 1; specifically, the metal plate is placed on the movable support platform 3 and the bending slot seat 2, the limiting pressure plate 6 moves toward one side of the movable support platform 3 to cover the top of the metal plate, and the hydraulic cylinder 5 controls the pressure head 4 to move downward to bend the metal plate. When the metal plate moves toward the center, the driving support platform also moves toward the side of the bending slot seat 2 synchronously, thereby avoiding the relative friction between the metal plate and the surface of the movable support platform 3 to cause wear and creases, and because of the role of the limiting pressure plates 6 set on both sides of the bending slot seat 2, the metal plate is also prevented from warping, thereby ensuring the correct forming of the metal plate.

[0026] like Figure 3 As shown, the mobile support platform 3 in this embodiment is provided with a plurality of moving wheels 7 at the bottom, and a track 8 adapted to the moving wheels 7 is installed on the bottom plate 1; a pushing cylinder 9 is connected to one end face of the mobile support platform 3; specifically, during the bending process of the pressure head 4, the mobile support platform 3 is driven by the pushing cylinder 9 to move toward the side of the bending groove seat 2, and the moving wheels 7 of the mobile support platform 3 move back and forth on the track 8, with a small moving resistance.

[0027] like Figure 1 As shown, a vertical plate 10 is arranged on the movable support platform 3, and the length of the metal plate is the distance between the two vertical plates 10. The metal plate is stuck between the two vertical plates 10, and a pad cloth 11 is arranged between the vertical plates 10 between the two movable support platforms 3. The pad cloth 11 is laid on the movable support platform 3 and the bending groove seat 2; specifically, when the metal plate is bent, the pad cloth 11 tube is driven to slide synchronously, and the pad cloth 11 will fit into the bending groove seat 2, avoiding direct contact between the metal plate and the bending groove seat 2, and avoiding the generation of creases on the metal plate to a certain extent. After completing the bending, the push-pull cylinder pulls the movable support seat back and resets, and the vertical plate 10 straightens the pad cloth 11 again to keep it flat.

[0028] like Figure 1 As shown, the two ends of the pad cloth 11 are fixedly connected to the vertical plate 10 to form an integrated structure. In order to facilitate the disassembly of the vertical plate 10 and the pad cloth 11, the vertical plate 10 is plugged into the movable support platform 3, and the vertical plate 10 can be separated from the movable support platform 3 by vertically lifting it.

[0029] Reference Figure 2 As shown, at least two guide rails 61 are provided on the base plate 1 in this embodiment, and the direction of the guide rails 61 is kept perpendicular to the movable support platform 3, and the limiting pressure plate 6 cooperates with the guide rails 61; specifically, when the metal plate is placed on the movable support platform 3, the limiting pressure plates 6 on both sides move toward one side of the movable support platform 3, so that the metal plate is pressed under the movable support plate, effectively preventing the two ends of the metal plate from warping up when the pressure head 4 is bent.

[0030] It can be explained that the limiting pressure plate 6 is an L-shaped structure.

[0031] like Figure 4 As shown, the hydraulic cylinder 5 in this embodiment is connected to the main rod 12, and the mounting plates 13 are screwed on both sides of the main rod 12, and a plug 131 is provided at the lower end of the mounting plate 13; the top of the pressure head 4 is in contact with the main rod 12, and the end faces on both sides of the pressure head 4 are provided with a card slot 41 that matches the plug 131; specifically, in order to replace different models of pressure heads 4 according to actual use and improve the scope of application, after loosening the screws between the mounting plate 13 and the main board, the pressure head 4 can be moved out laterally to separate the plug 131 and the card slot 41.

[0032] like Figure 1As shown, when the bending opening of the bending groove seat 2 is a V-shaped or U-shaped structure, the pressing head 4 presses on the metal plate to form a V-shaped or U-shaped bending angle.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
