Description

Technical Field

[0001] This utility model relates to the field of profile bending, and in particular to a positioning mechanism for profile bending. Background Technology

[0002] Profiles are long strips of metal or non-metal materials with specific cross-sectional shapes, made through processes such as extrusion, rolling, or casting. They are widely used in many fields such as construction, machinery manufacturing, transportation, and electronic equipment. In order to install and use profiles flexibly, they usually need to be bent with the help of bending devices to facilitate their use during construction.

[0003] When bending profiles, the equipment usually bends at a single angle, which limits the bending angle and the ways to assemble profiles. The flexibility of use is also limited. In addition, the bending point is limited, and bending can only be done at the center point, which is also quite restrictive. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and to propose a positioning mechanism for bending profiles, which improves the flexibility of the device in changing the bending angle of the profile and allows the device to flexibly adjust the bending point.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning mechanism for bending profiles, comprising:

[0007] A support platform for bottom support has a mounting bracket fixedly connected to its top end, a movable slider slidably connected to the top end of the mounting bracket, a fixed frame fixedly connected to the bottom end of the movable slider, an electric push rod fixedly connected inside the fixed frame, the output shaft of the electric push rod passing through the bottom end of the fixed frame and fixedly connected to a pressing sleeve, positioning support plates abutting both sides of the top end of the support platform, positioning pressing blocks slidably connected to the outer sides of the positioning support plates, and threaded rods fixedly connected to the middle of the bottom end of the positioning support plates. The bottom end of the support platform is connected to the outside of the threaded rods through a synchronous rotation lifting mechanism to achieve synchronous lifting of the positioning support plates on both sides.

[0008] A mounting base is used for the top of the mounting frame. A collecting roller is rotatably connected inside the mounting base. A drive motor is fixedly connected to the rear end of the mounting base. The drive end of the drive motor is fixedly connected to the rear end of the collecting roller. The outside of the collecting roller is connected to both sides of the movable slider through a traction rope to realize the left and right movement of the movable slider.

[0009] Furthermore, the traction rope includes movable ropes located on both sides of the movable slider, and tension rods are fixedly connected to both sides of the top of the mounting frame. The outer side of the movable rope surrounds the outer side of the tension rod and is wound around the outer side of the collecting roller.

[0010] Furthermore, the synchronous rotation lifting mechanism includes rotating sleeves located on both sides of the bottom end of the support platform. Multiple rotating sleeves are connected by belts. The inner side of each rotating sleeve is connected to the outer thread of a threaded rod. A toothed ring is fixedly connected to the outer side of the right rotating sleeve. A fixed frame is fixedly connected to the right side of the bottom end of the support platform. A gear is rotatably connected inside the fixed frame, and the gear meshes with the toothed ring.

[0011] Furthermore, a servo motor is fixedly connected to the bottom end of the fixed frame, and the drive end of the servo motor passes through the middle of the fixed frame and is fixedly connected to the middle of the gear.

[0012] Furthermore, limiting rods are fixedly connected to both sides of the bottom end of the positioning support plate, and the outer sides of the limiting rods are respectively slidably connected to both sides of the support platform.

[0013] Furthermore, the interior of the positioning pressing block is connected to the sliding groove of the positioning support plate through a fixing bolt, and the fixing bolt is externally threaded with a fixing sleeve.

[0014] Furthermore, the movable pull ropes on both sides are wound around the outside of the collecting roller in opposite directions, and the tension rods on both sides are placed in a staggered manner.

[0015] Furthermore, a limiting rod is fixedly connected inside the top slot of the mounting bracket, and the inner side of the movable slider is slidably connected to the outside of the limiting rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the synchronous rotation of the rotating sleeve contacts the threaded rod, causing the threaded rod to move upward simultaneously, thereby lifting the positioning support plates on both sides upward. The higher the positioning support plates are lifted, the smaller the bending angle, making the device more flexible in changing the bending angle of the profile and more convenient to use.

[0018] 2. In this utility model, by rotating the collecting roller, the two sides of the movable pull rope wound around it are in opposite directions. When the collecting roller rotates, one side is wound up and the other side is released, thereby pulling the movable slider to move. This allows the device to flexibly adjust the bending point, thereby improving the device's adaptability. Attached Figure Description

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a positioning mechanism for profile bending, comprising: a support platform 1 for bottom support, a mounting frame 4 fixedly connected to the top of the support platform 1, a movable slider 9 slidably connected to the top of the mounting frame 4, a fixed frame 8 fixedly connected to the bottom of the movable slider 9, an electric push rod 19 fixedly connected inside the fixed frame 8, the output shaft of the electric push rod 19 passing through the bottom of the fixed frame 8 and fixedly connected to a pressing sleeve 7, positioning support plates 2 abutting both sides of the top of the support platform 1, and positioning pressing blocks 3 slidably connected to the outer sides of the positioning support plates 2, as shown in the figure. Figure 5Each positioning support plate 2 has a threaded rod 17 fixedly connected to its bottom center. The bottom of the support platform 1 is connected to the outside of the threaded rod 17 via a synchronous rotation lifting mechanism to achieve synchronous lifting of the positioning support plates 2 on both sides. The synchronous rotation lifting mechanism includes rotating sleeves 16 located on both sides of the bottom of the support platform 1. Multiple rotating sleeves 16 are connected by belts. The inner side of the rotating sleeves 16 is threadedly connected to the outside of the threaded rod 17. A toothed ring 23 is fixedly connected to the outside of the right rotating sleeve 16. A fixing frame 21 is fixedly connected to the right side of the bottom of the support platform 1. The frame 21 is internally rotatably connected to a gear 20, which meshes with a gear ring 23. A servo motor 22 is fixedly connected to the bottom of the fixed frame 21. The drive end of the servo motor 22 passes through the middle of the fixed frame 21 and is fixedly connected to the middle of the gear 20. Limiting rods 18 are fixedly connected to both sides of the bottom of the positioning support plate 2. The external parts of the limiting rods 18 are slidably connected to both sides of the support platform 1. The internal part of the positioning pressing block 3 is connected to the sliding groove of the positioning support plate 2 through a fixing bolt 6. A fixing sleeve 15 is threadedly connected to the external part of the fixing bolt 6.

[0028] The profile to be bent is passed through the central slot of the positioning support plate 2. Then, the positioning pressing block 3 is moved downwards to fit tightly against the top of the profile. Next, the fixing sleeve 15 is rotated to make it press against the fixing bolt 6, thereby locking the position of the positioning pressing block 3 and achieving a stable fixation of the profile. At this time, according to the required bending angle of the profile, the servo motor 22 is started to rotate the gear 20. The meshing of the gear 20 and the gear ring 23 drives the right rotating sleeve 16 to rotate, while the other rotating sleeve 16 rotates synchronously through belt drive. The rotating sleeve 16 contacts the external thread of the threaded rod 17, causing the threaded rod 17 to move upwards, thereby causing the positioning support plates 2 on both sides to rise together. Finally, the electric push rod 19 is started to press the pressing sleeve 7 downwards to complete the bending of the profile. This device improves the flexibility of changing the bending angle of the profile and makes the operation more convenient.

[0029] Reference Figure 1 and Figure 2 A fixed base 10 is used for the top of the mounting frame 4. A collecting roller 12 is rotatably connected inside the fixed base 10. A drive motor 13 is fixedly connected to the rear end of the fixed base 10. The drive end of the drive motor 13 is fixedly connected to the rear end of the collecting roller 12. The outside of the collecting roller 12 is connected to both sides of the movable slider 9 through a traction rope to realize the left and right movement of the movable slider 9. The traction rope includes movable ropes 11 located on both sides of the movable slider 9. Tension rods 5 are fixedly connected to both sides of the top of the mounting frame 4. The outside of the movable ropes 11 surrounds the outside of the tension rods 5 and wraps around the outside of the collecting roller 12. The movable ropes 11 on both sides are wrapped around the outside of the collecting roller 12 in opposite directions. The tension rods 5 on both sides are placed in a staggered manner. A limiting rod 14 is fixedly connected inside the top slot of the mounting frame 4. The inside of the movable slider 9 is slidably connected to the outside of the limiting rod 14.

[0030] When adjusting the bending point of the profile, starting the drive motor 13 will cause the collecting roller 12 to rotate. Since the moving pull rope 11 is wound in opposite directions on both sides of the outside of the collecting roller 12, the tension rods 5 on both sides restrict the movement of the moving pull rope 11, ensuring that it is wound perpendicular to the collecting roller 12. In this way, the moving pull rope 11 on one side is wound up, while the other side is released, thereby pushing the moving slider 9 to move. This process adjusts the pressing angle of the pressing sleeve 7, so that the device can flexibly adjust the bending point, thereby enhancing the adaptability and versatility of the device.

[0031] Working principle: The profile to be bent is passed through the central slot of the positioning support plate 2. At this time, the positioning pressing block 3 is moved downward to fit the top of the profile. Then, the fixing sleeve 15 is rotated, causing the fixing sleeve 15 and the fixing bolt 6 to press against each other, thereby positioning and fixing the position of the positioning pressing block 3, completing the fixing of the profile. At this time, according to the bending degree that needs to be adjusted of the profile, the servo motor 22 is started to rotate the gear 20. The meshing between the gear 20 and the gear ring 23 rotates the right rotating sleeve 16. The other rotating sleeve 16 rotates synchronously with the belt drive. The rotating sleeve 16 contacts the external thread of the threaded rod 17. This moves the threaded rod 17 upwards, raising the positioning support plates 2 on both sides upwards. At this time, the electric push rod 19 is activated to press the pressing sleeve 7 downwards, thereby bending the profile. When adjusting the bending point of the profile, the drive motor 13 is activated to rotate the collecting roller 12. The moving pull rope 11 wrapped around the outside of the collecting roller 12 is wound in opposite directions on both sides, and the tension rods 5 on both sides restrict the moving pull rope 11, ensuring that the moving pull rope 11 is wrapped perpendicularly to the collecting roller 12. The moving pull rope 11 on one side is wound up, and the moving pull rope 11 on the other side is released, thereby moving the moving slider 9 and adjusting the downward angle of the pressing sleeve 7.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
