Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending machine moulds, in particular to a bending machine lower mould which can prevent deviation. Background Art
[0002] The lower die of the bending machine is one of the important components used in the bending machine for bending metal sheets. During the bending process, the metal sheet is placed between the upper and lower dies of the bending machine. Through the pressure of the upper die, the sheet is bent according to the shape of the lower die, thereby obtaining the desired shape and angle.
[0003] However, during the bending process, if there is no limiting mechanism on both sides to limit the metal sheet after it is subjected to force, it is easy to deviate, resulting in inaccurate bending position and affecting subsequent use.
[0004] Therefore, we propose a bending machine lower die which can prevent deviation. Utility Model Content
[0005] The purpose of the utility model is to provide a lower mold of a bending machine that can prevent deviation. The utility model is practical and convenient. By installing four limiting mechanisms on both sides of the lower mold of the bending machine, the two ends of the metal plate can be limited to prevent it from deviating, so as to solve the above-mentioned problems.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lower mold of a bending machine capable of preventing deviation, comprising a lower mold body, a driving mechanism located on the surfaces of two side plates of the lower mold body, and a limiting mechanism located on the upper end of the driving mechanism, wherein the side surface of the lower mold body is fixedly connected to the side surface of the driving mechanism;
[0007] The driving mechanism is provided with a bidirectional motor, a bidirectional screw and a moving block inside;
[0008] There are four limit mechanisms, and the side surfaces of the limit mechanisms are rotatably connected with a rotating shaft, the outer surface of the rotating shaft is fixedly connected with a limit plate, and the limit plate is rotatably connected to the side surface of the limit mechanism through the rotating shaft.
[0009] Preferably, a metal sheet element is placed on the upper surface of the lower mold body.
[0010] Preferably, the output end of the bidirectional motor is drivingly connected to the bidirectional screw, and the threads on both sides of the bidirectional screw are opposite.
[0011] Preferably, the outer surface of the bidirectional screw is threadedly connected to the moving block, and the upper surface of the moving block is fixedly connected to the lower surface of the limiting mechanism.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model discloses a bending machine lower die capable of preventing deviation. When in use, a metal plate element is placed on the upper end of the lower die body from top to bottom, such as Figure 1 As shown, after the placement is completed, the staff can drive the bidirectional motor, and the bidirectional motor drives the bidirectional screw with opposite threads at both ends to rotate, thereby driving the moving block and the limiting mechanism to move to both sides of the metal sheet element. By setting a movable limiting mechanism, it can be applied to metal sheet elements of various widths. When all four limiting mechanisms are in contact with the metal sheet element, as shown in FIG. Figure 2 As shown, the metal sheet element can be limited, thereby effectively preventing the metal sheet element from deflecting during bending and improving the bending accuracy.

[0019] 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. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4A lower mold of a bending machine capable of preventing deviation comprises a lower mold body 1, a driving mechanism 2 located on the surface of two side plates of the lower mold body 1, and a limiting mechanism 3 located at the upper end of the driving mechanism 2. The side surface of the lower mold body 1 is fixedly connected to the side surface of the driving mechanism 2. A bidirectional motor 21, a bidirectional screw 22 and a moving block 23 are arranged inside the driving mechanism 2. There are four limiting mechanisms 3. The side surface of the limiting mechanism 3 is rotatably connected with a rotating shaft 31. The outer surface of the rotating shaft 31 is fixedly connected with a limiting plate 32. The limiting plate 32 is rotatably connected to the side surface of the limiting mechanism 3 through the rotating shaft 31. A metal sheet element 4 is placed on the upper end of the lower mold body 1 from top to bottom, such as Figure 1 As shown, after the placement is completed, the staff can drive the bidirectional motor 21, and the bidirectional motor 21 drives the bidirectional screw 22 with opposite threads at both ends to rotate, thereby driving the moving block 23 and the limiting mechanism 3 to move to both sides of the metal sheet element 4. By setting a movable limiting mechanism 3, it can be applied to metal sheet elements 4 of various widths. When the four limiting mechanisms 3 are all in contact with the metal sheet element 4, as shown in FIG. Figure 2 As shown, the metal sheet element 4 can be limited, thereby effectively preventing the metal sheet element 4 from deflecting during bending. When the bending position needs to be more precise, the staff can also rotate the limit plate 32 through the rotating shaft 31, such as Figure 3 As shown, the front and rear ends or one end can be limited to further increase the anti-deviating effect. It should be noted that when the metal sheet element 4 is longer, the limiting plate 32 can be turned back to avoid obstructing the metal sheet element 4.
[0021] Furthermore, a metal sheet element 4 is placed on the upper surface of the lower mold body 1. When in use, the metal sheet element 4 is first placed on the upper end of the lower mold body 1, and then the metal sheet element 4 can be bent by pressing down with the upper mold.
[0022] Furthermore, the output end of the bidirectional motor 21 is connected to the bidirectional screw 22, and the threads on both sides of the bidirectional screw 22 are opposite. When in use, the bidirectional motor 21 drives the bidirectional screw 22 to rotate. Since the two sides of the bidirectional screw 22 are opposite, the moving blocks 23 at both ends can be driven to move in opposite directions or reverse directions.
[0023] Furthermore, the outer surface of the bidirectional screw 22 is threadedly connected to the moving block 23, and the upper surface of the moving block 23 is fixedly connected to the lower surface of the limiting mechanism 3. When in use, the movement of the moving block 23 can drive the limiting mechanism 3 fixedly connected thereto to move.
[0024] Working principle: The utility model is a lower mold of a bending machine that can prevent deviation. The present invention realizes precise limiting of metal sheet components 4 of different widths through a combination of a driving mechanism 2 and four limiting mechanisms 3, thereby effectively preventing the deviation of the sheet during the bending process. First, the metal sheet component 4 is placed on the upper surface of the lower mold body 1. The lower mold body 1 is the basis of the entire mold. The metal sheet component 4 will cooperate with the upper mold here to perform bending work. After the metal sheet component 4 is placed, the staff starts the bidirectional motor 21, and the bidirectional motor 21 drives the bidirectional screw 22 to rotate. Since the threads on both sides of the bidirectional screw 22 are opposite, the moving blocks 23 at both ends will drive the limiting mechanisms 3 to move to both sides of the metal sheet component 4. When the four limiting mechanisms 3 are all moved to the position of fitting and contacting the metal sheet component 4, the metal sheet component 4 is effectively limited to prevent it from deviating during bending. By rotating the limiting plate 32, the front and rear ends or one end of the metal sheet component 4 can be additionally limited as needed, further enhancing the anti-deviating effect, thereby enriching the overall function and increasing the overall applicability.
[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
