In the process of pressing the plate down by the pressing plate, a certain vibration is likely to be generated, which may easily cause the plate to shift, thereby easily affecting the quality of the finished product after the plate is pressed down. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a plate pressing machine with a limiting structure to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plate pressing machine with a limiting structure, comprising a workbench, a top frame is arranged on the top of the workbench, a hydraulic cylinder is installed on the top of the top frame, and a first pressing frame and a second pressing frame are movably connected to the inner side of the top frame above the workbench.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] 1. The existing plate pressing machine is prone to generate certain vibrations in the process of pressing the plate through the pressing plate, which may cause the plate to shift, thereby affecting the quality of the finished product after the plate is pressed. The utility model sets a limiting mechanism and a linkage mechanism. Since the No. 1 sliding frame and the threaded block are linked through the linkage frame and the No. 2 sliding frame, and the limiting plate and the No. 1 sliding frame are elastically connected through the supporting spring, the limiting plate can be closely fitted with the side wall of the plate to be pressed during the horizontal sliding of the threaded block, thereby limiting the plate to be pressed, preventing the plate to be pressed from shifting, and ensuring the quality of the finished product after the plate to be pressed is pressed.

[0015] 2. The existing press machine realizes the pressing operation of the plate by means of a pressing plate, but the size of the pressing plate is generally fixed, so that a single press machine can only be used for the pressing operation of plates of a single width, and the scope of application is relatively narrow. The utility model is provided with an adjustment mechanism. When the drive motor is working, the output end of the drive motor drives the two threaded rods to rotate together under the action of the pulley group. Since the threaded rod is threadedly connected to the threaded block, and the No. 1 pressing frame is slidably connected to the No. 2 pressing frame, the threaded block slides in the horizontal direction, thereby realizing the adjustment of the distance between the No. 1 pressing frame and the No. 2 pressing frame, so that the size of the pressing plate can be adjusted, so that it can be suitable for the pressing operation of plates to be pressed with various widths, thereby expanding the scope of application and improving the convenience of use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A plate pressing machine with a limiting structure, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a workbench 1, a top frame 2 is arranged on the top of the workbench 1, a hydraulic cylinder 3 is installed on the top of the top frame 2, and a No. 1 pressing frame 7 and a No. 2 pressing frame 8 are movably connected to the inner side of the top frame 2 above the workbench 1, and the No. 1 pressing frame 7 and the No. 2 pressing frame 8 are driven downward by the hydraulic cylinder 3, so that the pressing operation of the plate to be pressed can be realized by the No. 1 pressing frame 7 and the No. 2 pressing frame 8.

[0024] See also Figure 1 , Figure 2 and Figure 3 It can be seen that a linkage mechanism 5 is arranged between the No. 1 pressure frame 7, the No. 2 pressure frame 8 and the No. 1 sliding frame 401, and the linkage mechanism 5 is composed of a linkage frame 501, a No. 2 sliding frame 502 and a slide groove 503. The top of the workbench 1 is symmetrically provided with a slide groove 503 that forms a sliding structure with the No. 1 sliding frame 401. The top of the No. 1 sliding frame 401 is welded with the linkage frame 501, and the tops of the No. 1 pressure frame 7 and the No. 2 pressure frame 8 are both welded with the No. 2 sliding frame 502 that forms a sliding structure with the linkage frame 501. Since the No. 1 sliding frame 401 is linked with the threaded block 603 through the linkage frame 501 and the No. 2 sliding frame 502, during the horizontal sliding of the threaded block 603, the limit plate 402 can move horizontally with the threaded block 603, thereby facilitating the adjustment of the spacing between the two limit plates 402 and increasing convenience.

[0025] See also Figure 1 , Figure 2 and Figure 3 It can be seen that a limiting mechanism 4 is provided at the top of the workbench 1, and the limiting mechanism 4 consists of a No. 1 sliding frame 401, a limiting plate 402 and a supporting spring 403. The No. 1 sliding frame 401 is slidably connected to the top of the workbench 1, and one side of the No. 1 sliding frame 401 is slidably connected to the limiting plate 402. A supporting spring 403 is welded between the limiting plate 402 and the No. 1 sliding frame 401, and an inclined surface is provided at one end of the limiting plate 402. The limiting plate 402 and the No. 1 sliding frame 401 are both symmetrically arranged in two groups about the central axis of the workbench 1. When the linkage frame 501 slides horizontally, the limiting plate 402 can be closely fitted with the side wall of the sheet to be pressed, so that the limiting plate 402 can be used to limit the sheet to be pressed, so that the sheet to be pressed can be prevented from shifting, thereby ensuring the quality of the finished product after the sheet to be pressed is pressed down.

[0026] See also Figure 1 , Figure 2 and Figure 4It can be seen that an adjusting mechanism 6 connected to the hydraulic cylinder 3 is provided on the inner side of the top frame 2, and the adjusting mechanism 6 is composed of a support frame 601, a threaded rod 602, a threaded block 603 and a driving motor 604. The support frame 601 is welded and connected to one end of the hydraulic cylinder 3, and the threaded rod 602 is rotatably connected to the inside of the support frame 601 through a bearing. The outer surface of the threaded rod 602 is threadedly connected with a threaded block 603 welded and connected to the No. 1 pressing frame 7 and the No. 2 pressing frame 8. A driving motor 604 connected to one of the threaded rods 602 through a coupling is installed in the frame body on one side of the support frame 601. When the driving motor 604 is working, the output end of the driving motor 604 drives the two threaded rods 602 to rotate together under the action of the pulley group, so that the threaded block 603 slides in the horizontal direction, thereby realizing the adjustment of the spacing between the No. 1 pressing frame 7 and the No. 2 pressing frame 8, so that the size of the pressing plate can be adjusted, so that it can be applicable to the pressing operation of plates to be pressed with various widths, thereby expanding the scope of application and improving the convenience of use.

[0027] The working principle of the utility model is as follows: when using the plate pressing machine with a limiting structure, the plate to be pressed is placed on the surface of the workbench 1, and the driving motor 604 is started, so that the output end of the driving motor 604 drives the two threaded rods 602 to rotate together under the action of the pulley group, and then the threaded block 603, the No. 1 pressing frame 7, the No. 2 pressing frame 8, the linkage frame 501, the No. 1 sliding frame 401 and the limiting plate 402 slide in the horizontal direction, thereby adjusting the distance between the No. 1 pressing frame 7 and the No. 2 pressing frame 8, and at the same time making the limiting plate 402 fit closely with the side wall of the plate to be pressed, thereby limiting the plate to be pressed, at this time, the No. 1 pressing frame 7 and the No. 2 pressing frame 8 are driven downward by the hydraulic cylinder 3, so that the pressing operation of the plate to be pressed can be realized by the No. 1 pressing frame 7 and the No. 2 pressing frame 8.
