Description

Technical Field

[0001] This utility model relates to the field of pipe bending forming technology, specifically a pipe bending forming mold. Background Technology

[0002] Pipes are divided into straight pipes and bent pipes. Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, etc. They are mainly used for oil, gas, and liquid transportation. Most of them are used in engineering bridge construction, etc. Straight pipes can be pressed into the required bent pipes through a one-time forming mold, which facilitates the stable use of the pipeline. However, the clamping method of traditional pipe bending molds is relatively simple, and the pipe is prone to slippage during processing, resulting in a reduction in forming accuracy. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Example 1

[0019] Please see Figure 1-4 In this embodiment: a pipe bending forming mold includes a base 1, a worktable 2 fixedly connected to the upper surface of the base 1, a forming component 3 mounted on one side of the upper surface of the worktable 2, and a mounting frame 4 slidably connected to the other side of the upper surface of the worktable 2. A fixed plate 5 is fixedly connected to the middle of the mounting frame 4, and turntables 6 are rotatably connected to both sides of the mounting frame 4. Slide grooves 7 are provided on both sides of the fixed plate 5, and a connecting groove 8 is provided on one side of each slide groove 7. Slide rods 9 are slidably connected to the inner walls of each slide groove 7. One end of each is fixedly connected to a slider 10, the outer wall of the slider 10 is slidably connected to the inner wall of the connecting groove 8, a clamping plate 11 is fixedly connected to one side of the slider 10, through grooves 12 are opened on both sides of the surface of the turntable 6, the outer wall of the slide rod 9 is slidably connected to the inner wall of the through groove 12, a fixing plate 13 is fixedly connected to one side of the outer wall of the turntable 6, a support frame 14 is rotatably connected to the surface of the fixing plate 13, a screw sleeve 15 is fixedly connected to one side of the support frame 14, and a screw rod 16 is threadedly connected to the inner wall of the screw sleeve 15.

[0020] In this embodiment, the outer wall of the screw 16 is provided with opposite threads on both sides. By rotating the screw 16, the screw sleeve 15 moves inward at the same time, thereby causing the support frame 14 to rotate on the fixed plate 13. This causes the fixed plate 13 to drive the two turntables 6 to rotate. The turntables 6 drive the slide rod 9 to slide in the through groove 12, so that the slide rod 9 can translate along the slide groove 7. When the slide rod 9 moves, it drives the slider 10 to translate along the connecting groove 8, thereby enabling the clamping plate 11 to clamp and fix the pipe. Then, the forming component 3 bends the pipe to ensure that the pipe does not shift or deform during the bending process.

[0021] Furthermore, the molding component 3 includes a servo motor 301. One side of the outer wall of the servo motor 301 is fixedly connected to one side of the upper surface of the worktable 2. A rotating rod 302 is fixedly connected to the output end of the servo motor 301. A connecting frame 303 is fixedly connected to the outer wall of the rotating rod 302. A positioning block 304 is fixedly connected to one side of the upper surface of the connecting frame 303. A hydraulic rod 305 is fixedly connected to the other side of the upper surface of the connecting frame 303. A locking block 306 is fixedly connected to the output end of the hydraulic rod 305. A fixing rod 307 is fixedly connected to one side of the lower surface of the worktable 2. The lower part of the connecting frame 303 is rotatably connected to the outer wall of the fixing rod 307.

[0022] The pipe is placed on one side of the positioning block 304, and then the hydraulic rod 305 is activated to move the clamping block 306 to clamp the pipe. Then the servo motor 301 is activated, which drives the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the connecting frame 303 to rotate, thereby adjusting the position of the positioning block 304, and thus accurately positioning and bending the pipe.

[0023] Furthermore, a hydraulic rod 17 is fixedly connected to one side of the middle part of the workbench 2, and a locking block 18 is fixedly connected to the output end of the hydraulic rod 17.

[0024] After the pipe is placed, the hydraulic rod 217 is activated to drive the clamp 218 to press against one side of the pipe to ensure that the pipe does not shift or deform during the bending process.

[0025] Furthermore, both sides of the upper surface of the worktable 2 are fixedly connected to a mounting bracket 19. A rotating shaft 20 is rotatably connected to the surface of one of the mounting brackets 19. A drive motor 22 is fixedly connected to one side of the outer wall of the worktable 2. The output end of the drive motor 22 is fixedly connected to one end of the rotating shaft 20. The lower side of the mounting bracket 4 is threadedly connected to the outer wall of the rotating shaft 20. A guide rod 21 is fixedly connected to the surface of the other mounting bracket 19. The lower other side of the mounting bracket 4 is slidably connected to the outer wall of the guide rod 21.

[0026] Specifically, by starting the drive motor 22 to drive the rotating shaft 20 to rotate, the mounting bracket 4 can be moved with the help of the guide rod 21, thereby moving the pipeline to adjust its position.

[0027] Preferably, the centers of the rotating rod 302, the positioning block 304, and the fixing rod 307 are on the same axis.

[0028] The working principle and usage process of this utility model are as follows: By rotating the screw 16, the screw sleeve 15 moves inward simultaneously, thereby causing the support frame 14 to rotate on the fixed plate 13. This causes the fixed plate 13 to drive the two turntables 6 to rotate, and the turntables 6 drive the slide rod 9 to slide in the through groove 12, allowing the slide rod 9 to translate along the slide groove 7. When the slide rod 9 moves, it drives the slider 10 to translate along the connecting groove 8, thereby enabling the clamping plate 11 to clamp and fix the pipe, placing the pipe on one side of the positioning block 304. Then, the hydraulic rod 2 17 is activated, causing the clamping block 2 18 to abut against one side of the pipe. The hydraulic rod 1 305 is activated, causing the clamping block 1 306 to move, thus clamping the pipe. Then, the servo motor 301 is activated, which drives the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the connecting frame 303 to rotate, thereby adjusting the position of the positioning block 304, and thus accurately positioning and bending the pipe.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
