Description

Technical Field

[0001] This utility model relates to the field of back gauge for bending machines, specifically a novel back gauge device for bending machines. Background Technology

[0002] The back gauge of a bending machine is a mechanism that limits the amount of sheet material entering the machine, preventing the amount of sheet material from being too much or too little, thus facilitating more precise processing.

[0003] In the prior art, the back gauge can generally move in the vertical and axial directions to accommodate different feed amounts or different thicknesses of the sheet material.

[0004] The existing top beam moving power is generally a multi-guide rod mechanism, which is coordinated with the output power. This setting is prone to the problem that during long-term movement, the friction causes uneven force on the left and right sides, resulting in inconsistent movement on both sides. This, in turn, leads to inconsistent entry of the plate material on both sides, resulting in defective products. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a novel back gauge device for a bending machine includes a mounting frame 1. A first reversible motor 2 is mounted on the side plate of the mounting frame 1. A hollow top beam 9 is provided above the end plate of the mounting frame 1. A second reversible motor 8 is mounted on the bottom end of the top beam 9. The output end of the second reversible motor 8 and the output end of the first reversible motor 2 are both connected to a transmission mechanism. A baffle 10 is slidably mounted on the top of the top beam 9. A first transmission screw 7 is connected to the output end of the transmission mechanism connected to the first reversible motor 2. A second transmission screw 17 is connected to the output end of the transmission mechanism connected to the second reversible motor 8. An axial sliding plate 11 is connected to the outer wall of the first transmission screw 7 through a first screw seat 14. A fixed plate 15 is connected to the outer wall of the second transmission screw 17 through a second screw seat 16. The second screw seat 16 is fixedly connected to the fixed plate 15. The fixed plate 15 is fixedly connected to the axial sliding plate 11, and a sliding cavity for sliding plate 19 exists between the fixed plate 15 and the axial sliding plate 11.

[0021] In this embodiment: First, when it is necessary to move the baffle 10 up and down or left and right by driving the top beam 9, the corresponding first reversible motor 2 or second reversible motor 8 is started. The running first reversible motor 2 or second reversible motor 8 drives the transmission mechanism connected to it to rotate. The corresponding transmission mechanism drives the first transmission screw 7 or second transmission screw 17 connected to it to rotate, thereby realizing the up and down or left and right movement of the top beam 9.

[0022] Please refer to this carefully. Figure 1 and Figure 4The transmission mechanism includes a tensioner 5, a power wheel 6, and a transmission wheel assembly. A set of transmission wheel assemblies includes two transmission wheels 4, which are connected by a transmission belt 3. The transmission belt 3 is wrapped around the outside of the tensioner 5, the power wheel 6, and the two transmission wheels 4.

[0023] In this embodiment: when the No. 1 forward and reverse motor 2 or the No. 2 forward and reverse motor 8 is started, the power wheel 6 connected to its output end rotates. The rotation of the power wheel 6 drives the transmission belt 3 to drive the two transmission wheels 4 to rotate synchronously and in the same direction.

[0024] It should be noted that the tensioner 5 is designed to ensure effective transmission and prevent the transmission belt 3 from slipping.

[0025] Please refer to this carefully. Figure 1 and Figure 4 The tension wheel 5 and the power wheel 6, which are connected to the side plate of the mounting frame 1, are rotatably connected to the mounting frame 1. The two transmission wheels 4, which are connected to the side plate of the mounting frame 1, are fixedly connected to one end of the two No. 1 transmission screws 7 respectively. The No. 1 transmission screws 7 are rotatably connected to the mounting frame 1 through bearings. The inner side of the two end plates of the mounting frame 1 is fixedly connected to the No. 1 guide rail 12. The outer wall of the No. 1 guide rail 12 is slidably connected to the No. 1 slider 13. The side of the two No. 1 sliders 13 that are close to each other is fixedly connected to the top and bottom ends of the No. 1 screw seat 14.

[0026] In this embodiment: the No. 1 forward and reverse motor 2 is running, and the No. 1 forward and reverse motor 2 drives the transmission mechanism at its output end to run. The No. 1 forward and reverse motor 2 drives the two No. 1 transmission screws 7 to rotate through the transmission mechanism. At this time, the No. 1 screw seat 14 moves back and forth in the axial direction. The No. 1 screw seat 14 drives the two No. 1 sliders 13 to slide on the outside of the No. 1 guide rail 12. At the same time, the axial sliding plate 11 drives the top beam 9 to move back and forth.

[0027] Please refer to this carefully. Figure 3 and Figure 4 The tension wheel 5 and the power wheel 6 connected to the top beam 9 are rotatably connected to the top beam 9. The bottom ends of the two transmission wheels 4 connected to the top beam 9 are rotatably connected to the bottom ends of the two second transmission screws 17. The second transmission screws 17 are rotatably connected to the top beam 9. One end of the slide plate 19 is fixedly connected to the second guide rail 20. The outer wall of the second guide rail 20 is slidably connected to the second slider 18. One end of the second slider 18 is fixedly connected to the fixed plate 15.

[0028] In this embodiment: When the No. 2 forward and reverse motor 8 is running, the No. 2 forward and reverse motor 8 drives the two No. 2 transmission screws 17 to rotate through the transmission mechanism connected to it. Since the No. 2 screw seat 16 is fixed and cannot move up and down, the two No. 2 transmission screws 17 move up and down under the opposite force, and at the same time drive the slide plate 19 to slide up and down in the sliding cavity between the axial sliding plate 11 and the fixed plate 15. Meanwhile, the No. 2 guide rail 20 slides up and down on the inner wall of the No. 2 slider 18, so as to realize the up and down movement of the top beam 9.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
