Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and specifically to an automatic positioning bending device. Background Technology

[0002] When machining stiffener plates using a hydraulic lathe, the position of the stiffener plates needs to be limited so that the bending point of the stiffener plates is directly below the bending cutter, in order to avoid the stiffener plates shifting during bending.

[0003] Chinese patent document CN210231093U discloses a bending device for manufacturing a hydraulic rib plate structure, including a lower bending die, an upper bending die, and a rib plate component. The lower bending die is matched with the upper bending die. The lower bending die has a placement groove that matches the rib plate component. A pushing block is slidably connected to the upper bending die. A first spring is fixedly connected to the end of the pushing block away from the lower bending die. The end of the first spring away from the pushing block is fixedly connected to the upper bending die. A bending groove is provided inside the lower bending die. A bending template is slidably connected inside the bending groove. A driven block is fixedly connected to the bending template. The end of the pushing block away from the first spring penetrates the upper wall of the lower bending die. The pushing block matches the driven block.

[0004] However, in the above scheme, the placement groove is used to position the stiffening plate. Since the bending point of the stiffening plate is a fixed point, the placement groove needs to be closely connected with the stiffening plate to accurately position the bending point of the stiffening plate, which makes it relatively difficult to place the stiffening plate inward into the placement groove.

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic positioning bending device.

[0006] The technical solution of this utility model is: an automatic positioning bending device, including a worktable, a bending groove, a feeding assembly and a limiting assembly;

[0038] Example 1

[0039] like Figure 1-4 As shown, the present invention proposes an automatic positioning bending device, which includes a worktable 1, a bending groove 12, a feeding assembly and a limiting assembly.

[0040] A bending groove 12 is provided on the upper end face of one end of the workbench 1, and a bending assembly extending into the bending groove 12 and pressing the rib plate is provided above the bending groove 12.

[0041] The number of limiting components is two, and the two limiting components are respectively set on both sides of the upper end face of the worktable 1 and located on both sides of the bending groove 12;

[0042] The feeding assembly is located on the upper surface of the other end of the workbench 1 and is arranged coaxially with the center of the bending groove 12;

[0043] The bending groove 12 includes a first groove 121 and a second groove 122;

[0044] The first groove 121 is located on the upper surface of one end of the workbench 1 and near the edge;

[0045] The second groove 122 is located at the edge of the upper surface of one end of the workbench 1 and communicates with the first groove 121, and the depth of the second groove 122 is greater than the depth of the first groove 121.

[0046] In this embodiment, the placement of the ribs is limited by two limiting components, allowing multiple ribs to be arranged between the two limiting components. The feeding component pushes the multiple ribs sequentially upwards towards the first groove 121, causing the bending component to extend into the bending groove 12 and press the multiple ribs sequentially. Through the cooperation between the inner wall of the first groove 121 and the bending component, the multiple ribs are bent sequentially. At the same time, the feeding component pushes the bent ribs towards the inside of the second groove 122. During the processing of the ribs to be bent, the bending component performs a second bend on the ribs that have been bent once, preventing the ribs from springing back. As the ribs are continuously processed, the side of the rib to be bent contacts the side of the end of the first-bent rib, pushing the first-bent rib towards the inside of the second groove 122. Simultaneously, the side of the first-bent rib contacts the side of the second-bent rib, pushing the second-bent rib towards the outside of the second groove 122, thus facilitating the unloading of the ribs.

[0047] Example 2

[0048] like Figure 4 As shown, the present invention proposes an automatic positioning bending device. Compared with the first embodiment, the bending assembly includes a support frame 8, a bending blade 9, a mounting block 10, and a hydraulic cylinder 11.

[0049] The support frame 8 is installed at one end of the workbench 1;

[0050] The hydraulic cylinder 11 is installed in the middle of the support frame 8 and is located directly above the bending groove 12;

[0051] Mounting block 10 is located inside support frame 8 and connected to the end of hydraulic cylinder 11;

[0052] The bending blade 9 is installed at the bottom of the mounting block 10.

[0053] In this embodiment, the bending knife 9 is installed at the end of the hydraulic cylinder 11 by the mounting block 10, so that the hydraulic cylinder 11 drives the bending knife 9 to move inward to the bending groove 12 through the mounting block 10 in the middle of the support frame 8, so that the bending knife 9 cooperates with the bending groove 12 to perform bending work on the rib plate.

[0054] Example 3

[0055] like Figure 4As shown, the present invention proposes an automatic positioning bending device. The difference between this embodiment and embodiment two is that the bending blade 9 includes a blade body 91, a first blade head 92, and a second blade head 93.

[0056] The blade 91 is installed at the bottom of the mounting block 10;

[0057] The first cutting head 92 is located on one side of the bottom end of the blade 91 and above the bending groove 12;

[0058] The second cutter head 93 is located at the bottom of the mounting block 10, on one side of the first cutter head 92, and above the bending groove 12.

[0059] In an optional embodiment, the length values ​​of the first groove 121 and the second groove 122 are the same as the length values ​​of the first cutter head 92 and the second cutter head 93, respectively.

[0060] In this embodiment, the blade 91 drives the first cutter head 92 and the second cutter head 93 to extend into the first groove 121 and the second groove 122 respectively. When the first cutter head 92 and the first groove 121 work together to bend the rib plate once, the second cutter head 93 and the second groove 122 work together to bend the rib plate a second time, thereby improving the bending effect of the rib plate.

[0061] Example 4

[0062] like Figure 3 As shown, the present invention proposes an automatic positioning bending device. The difference between this embodiment and the first embodiment is that the feeding assembly includes a telescopic rod 3 and a push plate 2.

[0063] The telescopic rod 3 is set on the upper surface of the other end of the workbench 1 and one end extends into the bending groove 12;

[0064] The push plate 2 is installed at one end of the telescopic rod 3 and arranged parallel to the edge of the bending groove 12, so as to arrange the stiffener plate parallel to the edge of the bending groove 12 during use.

[0065] In an optional embodiment, a baffle 4 is provided at the end of a limiting component, which blocks the rib plate and causes the rib plate to be placed towards the end of the feeding component.

[0066] In this embodiment, the baffle 4 blocks the rib plate, so that the rib plate is located on the side between the two limiting components. The telescopic rod 3 drives the push plate 2 to extend towards the first groove 121, so that the push plate 2 moves the rib plate between the two limiting components and moves it towards the bending groove 12 between the two limiting components to perform bending work, making it easier to load the rib plate.

[0067] Example 5

[0068] like Figure 3 As shown, the present invention proposes an automatic positioning bending device. Compared with the first embodiment, the difference in this embodiment is that the limiting component includes a limiting plate 5, a connecting plate 6, and a bolt 7.

[0069] The connecting plate 6 is mounted on the upper surface of the workbench 1 by bolts 7;

[0070] The limiting plate 5 is installed at the end of the connecting plate 6 and is slidably connected to the worktable 1.

[0071] In an optional embodiment, the surface of the connecting plate 6 is provided with a waist-shaped hole 13, through which the bolt 7 passes to connect to the workbench 1.

[0072] In this embodiment, the connecting plate 6 is installed on the upper surface of the workbench 1 by bolts 7, so that the connecting plate 6 drives the limiting plate 5 to restrict the movement direction and position of the rib plate. The connecting plate 6 avoids the opening of the waist-shaped hole 13, so that the position of the limiting plate 5 can be adjusted on the upper surface of the workbench 1, and the limiting plate 5 can limit the movement direction and position of rib plates of different lengths.

[0073] In summary, in this utility model, bolt 7 installs connecting plate 6 on the upper surface of workbench 1, causing connecting plate 6 to drive limiting plate 5 to restrict the movement direction and position of rib plate, and baffle 4 to block rib plate, so that rib plate is placed on the side of push plate 2. At the same time, telescopic rod 3 drives rib plate to move, so that multiple rib plates are arranged between two limiting plates 5, and the thrust of telescopic rod 3 moves multiple rib plates along the side of limiting plate 5 to the upper part of first groove 121 in sequence. At the same time, hydraulic cylinder 11 drives bending cutter 9 to move inward to bending groove 12 through mounting block 10 in the middle of support frame 8, so that first cutter head 92 moves the rib plate above first groove 121 inward to the inner side of first groove 121. The material is pressed and bent through the inner wall of the first groove 121. By resetting the bending knife 9, the rib plate to be bent is pushed towards the inner side of the second groove 122 by the thrust of the telescopic rod 3, and the bending knife 9 continues to extend downward, so that the first cutter head 92 and the second cutter head 93 bend the rib plate above the first groove 121 and the inner side of the second groove 122 respectively, so that the rib plate is bent multiple times, improving the bending effect of the rib plate and avoiding the rib plate from springing back. As the rib plate continues to move towards the bending groove 12, the rib plate inside the bending groove 12 moves to the outside of the bending groove 12, making the discharge of the rib plate more convenient.

[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
