Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing, specifically a pipe fitting curvature adjustment device. Background Technology

[0002] Pipes are typically straight when manufactured, but various industries often require pipes with curved shapes. A pipe bending machine is a new type of pipe bending tool that can bend pipes into the desired shape. The pipe bending adjustment mechanism is an important component of the pipe bending machine, used to adjust the bending degree of the pipes.

[0003] According to Chinese Patent No. CN221184294U, an adjustment device for the curvature of metal pipe fittings is disclosed. This utility model can intuitively know the number of rotations of the drive rod and calculate the height of the shell descent, thereby realizing the control and adjustment of the curvature of the metal pipe fitting. In addition, the curvature of the metal pipe fitting can also be intuitively judged by the protractor on one side of the U-shaped frame, so as to facilitate the adjustment and control of the curvature of the metal pipe fitting.

[0004] Regarding the aforementioned patent content, a protractor is provided to measure the curvature of pipe fittings, and a shield is provided to cover the surface or back of the protractor to prevent external objects from hitting the protractor and scratching the scale. However, the shield needs to be removed when using the protractor and reinstalled after use to protect the protractor. This method is cumbersome, requiring frequent removal and removal of the shield. Furthermore, this method only protects the surface of the protractor, while the edges are still exposed to the external environment. As a result, the edges of the protractor can still be scratched when they collide with external objects, thus reducing the protective effect of the shield. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pipe bending adjustment device to solve the technical problem of poor protection effect on protractors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending adjustment device, comprising a base plate and a lifting rod. A fixed frame is installed on the top of the base plate, and a protective cover is installed inside the fixed frame via bolts. A U-shaped frame is installed at the bottom of the lifting rod via bolts. A positioning groove is provided inside the U-shaped frame, and a positioning block is inserted inside the positioning groove. Insertion holes are provided on both sides of the positioning block. Side frames are fixed on the top of both sides of the U-shaped frame, and springs are installed inside the side frames. One end of the spring is connected to a movable block, and a rod extending into the insertion hole is fixed on one side of the movable block. A pull rod penetrating to the outside of the side frame is installed on the other side of the movable block.

[0007] By adopting the above technical solution, when the protractor needs to be disassembled, the operator can pull the lever, which will move the movable block, which in turn will move the insertion rod. Once the insertion rod is removed from the insertion hole, the limiting position on the positioning block can be released.

[0008] Furthermore, the outer wall of the insertion rod is fitted with a rubber sleeve, and the outer wall of the rubber sleeve fits against the inner wall of the insertion hole.

[0009] By adopting the above technical solution, the rubber sleeve can improve the stability of the insertion rod when it is inserted into the insertion hole and prevent the insertion rod from sliding randomly.

[0010] Furthermore, the positioning block is adapted to the positioning groove, and the insertion rod is adapted to the insertion hole.

[0011] By adopting the above technical solution, the positioning block can be inserted into the positioning slot to position the protractor.

[0012] Furthermore, a frame is installed on the top of the fixing bracket, a servo motor is installed on the top of the frame, a speed reducer is installed inside the frame, the output shaft of the servo motor is connected to the speed reducer, and a threaded rod is connected to the output end of the speed reducer.

[0013] By adopting the above technical solution, the servo motor can drive the threaded rod to rotate, and the threaded rod in turn drives the threaded block to move.

[0014] Furthermore, the outer wall of the threaded rod is threadedly connected to a threaded block, and a lifting rod is installed on one side of the bottom of the threaded block.

[0015] By adopting the above technical solution, when the threaded rod rotates, it will drive the threaded block to move, and then drive the lifting rod to move, so as to adjust the position of the lifting rod.

[0016] Furthermore, a limiting rod is installed inside the frame, and the limiting rod passes through the threaded block.

[0017] By adopting the above technical solution, the limiting rod can guide the threaded block, thereby improving the stability of the threaded block during movement.

[0018] Furthermore, the U-shaped frame has two movable columns installed inside, and the fixed frame has fixed columns installed on both sides, with two baffles fitted on the outer wall of the fixed columns.

[0019] By adopting the above technical solution, the baffle can slide on the fixed column, thereby adjusting the position of the baffle.

[0020] Furthermore, the two sides of the fixing frame are connected to a second bidirectional lead screw via bearings, and the outer wall of the second bidirectional lead screw is fitted with two second threaded seats, the top of the second threaded seats being fixedly connected to the bottom of the baffle.

[0021] By adopting the above technical solution, when the second bidirectional lead screw rotates, it will drive the second threaded seat to move, and the second threaded seat will drive the baffle to move.

[0022] Furthermore, a protractor is mounted on the back of the positioning block, and the protractor is located inside the protective cover.

[0023] By adopting the above technical solution, the protective cover can shield and protect the protractor.

[0024] Furthermore, a base frame is installed on the top of the base plate, and a first bidirectional lead screw is connected to the inside of the base frame through a bearing. Two first threaded seats are sleeved on the outer wall of the first bidirectional lead screw. A through groove is opened on the top of the base frame, and a support frame is installed through the through groove and bolted on the top of the first threaded seat. A support wheel is rotatably provided on the top of the support frame. One end of the first bidirectional lead screw extends to the outside of the base frame and is equipped with a first rotating handle.

[0025] By adopting the above technical solution, it is convenient for the staff to rotate the first bidirectional lead screw through the first handle. The rotation of the first bidirectional lead screw will drive the two first threaded seats to move, and the first threaded seats will drive the support frame to move.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model features a protective cover made of polycarbonate. Before use, the protractor moves down with the U-shaped frame, allowing it to exit the protective cover without obstructing the protractor. After use, the U-shaped frame moves up, pulling the protractor back into the protective cover. This design protects both the surface and edges of the protractor, preventing metal parts from scratching the scale during transport and slowing down wear, thus improving reading accuracy. Furthermore, this design eliminates the need for frequent disassembly of the protective cover, making operation simple and convenient.

[0028] 2. This utility model is equipped with a positioning block, a positioning groove, a plug rod, a plug hole, a side frame, a spring, a pull rod, and a movable block. When the protractor needs to be disassembled for replacement, the operator can pull the pull rod, which in turn moves the movable block. The movable block then moves the plug rod. Once the plug rod moves out of the plug hole, the positioning block is released. At this point, the protractor can be moved so that the positioning block moves out of the positioning groove, thus allowing the protractor to be removed for replacement. This prevents the continued use of protractors with unclear scales or damage. The disassembly and assembly process is simple and convenient, thereby improving the efficiency of disassembly, assembly, and replacement of protractors.

[0029] 3. This utility model has a rubber sleeve, the outer wall of which fits against the inner wall of the socket, thereby improving the stability of the plug insertion into the socket and preventing the plug from sliding randomly. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of this utility model will be described below based on its overall structure.

[0042] Example 1:

[0043] A pipe fitting curvature adjustment device, such as Figures 1-9 As shown, the device includes a base plate 1 and a lifting rod 9. A fixing frame 2 is installed on the top of the base plate 1. A protective cover 31 is bolted to the upper part of the fixing frame 2. A U-shaped frame 10 is bolted to the bottom of the lifting rod 9. A positioning groove 22 is provided inside the U-shaped frame 10, and a positioning block 23 is inserted into the positioning groove 22. Insertion holes 26 are provided on both sides of the positioning block 23. Side frames 27 are fixed to the upper sides of both sides of the U-shaped frame 10, and springs 28 are installed inside the side frames 27. One end of the spring 28 is connected to a movable block 30, and a rod 24 extending into the insertion hole 26 is fixed to one side of the movable block 30. A pull rod 29 penetrating to the outside of the side frame 27 is installed on the other side of the movable block 30. The spring 28 is made of stainless steel. When disassembly is required... When the protractor 32 is in use, the operator can pull the lever 29, which in turn moves the movable block 30. The movable block 30 then moves the insertion rod 24. Once the insertion rod 24 moves out of the insertion hole 26, the limiting position on the positioning block 23 can be released. The thickness of the protective cover 31 is greater than the sum of the thicknesses of the positioning block 23 and the protractor 32, so that the protective cover 31 has enough space for the protractor 32 and the positioning block 23 to move. When disassembling the protractor 32, after the limiting position on the protractor 32 is released, the protractor 32 can be pushed so that both the protractor 32 and the positioning block 23 can move deeper into the protective cover 31. This makes it easier to move the positioning block 23 out of the positioning groove 22, and then the protractor 32 can be removed. In other words, the protractor 32 can be removed without disassembling the protective cover 31.

[0044] See Figures 2-9 The positioning block 23 is adapted to the positioning groove 22, and the insertion rod 24 is adapted to the insertion hole 26. The positioning block 23 can be inserted into the positioning groove 22 to position the protractor 32. A frame 3 is installed on the top of the fixing frame 2, and a servo motor 4 is installed on the top of the frame 3. A reducer 5 is installed inside the frame 3. The output shaft of the servo motor 4 is connected to the reducer 5. A threaded rod 6 is connected to the output end of the reducer 5. A threaded block 8 is threadedly connected to the outer wall of the threaded rod 6, and a lifting rod 9 is installed on one side of the bottom of the threaded block 8. When the threaded rod 6 rotates, it will drive the threaded block 8 to move, and then drive the lifting rod 9 to move, so as to adjust the position of the lifting rod 9.

[0045] Specifically, the U-shaped frame 10 has two movable columns 11 installed inside, and the fixed frame 2 has fixed columns 18 installed on both sides. The outer walls of the fixed columns 18 are fitted with two baffles 19, which can slide on the fixed columns 18 to adjust their positions. The fixed frame 2 also has second bidirectional lead screws 20 connected to both sides via bearings. The outer walls of the second bidirectional lead screws 20 are fitted with two second threaded seats 21. The tops of the second threaded seats 21 are fixedly connected to the bottoms of the baffles 19, and the baffles 19 are slidably connected to the fixed columns 18. When the second bidirectional lead screws 20... When the lead screw 20 rotates, it drives the second threaded seat 21 to move, and the second threaded seat 21 drives the baffle 19 to move. A protractor 32 is installed on the back of the positioning block 23. The protractor 32 is located inside the protective cover 31. The protective cover 31 is made of polycarbonate material and can shield and protect the protractor 32. One end of the second bidirectional lead screw 20 extends to the outside of the fixed frame 2 and is equipped with a second rotating handle, which makes it convenient for the staff to rotate the second bidirectional lead screw 20 through the second rotating handle. The insertion rod 24 is slidably connected to the side frame 27 through the movable block 30.

[0046] See Figures 1-6 A base frame 12 is installed on the top of the base plate 1. A first bidirectional lead screw 13 is connected to the inside of the base frame 12 via bearings. Two first threaded seats 14 are sleeved on the outer wall of the first bidirectional lead screw 13. A through groove is opened on the top of the base frame 12. A support frame 16 is installed through the through groove and bolted to the top of the first threaded seat 14. A support wheel 17 is rotatably installed on the top of the support frame 16. The first threaded seat 14 is slidably connected to the through groove. One end of the first bidirectional lead screw 13 extends to the outside of the base frame 12 and is equipped with a first rotating handle, which allows the operator to rotate the first bidirectional lead screw 13. The rotation of the first bidirectional lead screw 13 will drive the two first threaded seats 14 to move, and the first threaded seats 14 will drive the support frame 16 to move. A guide rod 15 is installed inside the base frame 12. The guide rod 15 passes through the first threaded seats 14 to guide the first threaded seats 14.

[0047] Example 2:

[0048] Based on the above embodiment 1, in order to improve the stability of the insertion rod 24 into the insertion hole 26, the following structure will be set.

[0049] Specifically, a rubber sleeve 25 is fitted on the outer wall of the insertion rod 24, and the outer wall of the rubber sleeve 25 fits against the inner wall of the insertion hole 26. The rubber sleeve 25 can improve the stability of the insertion rod 24 when it is inserted into the insertion hole 26 and prevent the insertion rod 24 from sliding at will.

[0050] Example 3:

[0051] Based on the above embodiment 1, in order to improve the stability of the threaded block 8 when it moves, it is necessary to guide the threaded block 8, so the following structure will be set.

[0052] See Figures 1-8 A limiting rod 7 is installed inside the frame 3. The limiting rod 7 passes through the threaded block 8 and can guide the threaded block 8, thereby improving the stability of the threaded block 8 when it moves.

[0053] The working principle of this utility model is as follows: First, when using it, the operator connects the power supply, then passes a small or medium-sized metal pipe through a pair of movable columns 11, while simultaneously making the support wheel 17 contact the metal pipe, and placing the entire metal pipe on top of a pair of fixed columns 18. Then, the operator rotates the second bidirectional screw 20 through the second handle. The rotation of the second bidirectional screw 20 drives the second threaded seat 21 to move, which in turn drives the baffle 19 to move, so that the baffle 19 fits against the metal pipe. Then, the operator stops rotating the second handle, which can then provide support for the metal pipe. The limit switch then activates the servo motor 4, which drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 causes the threaded block 8 to move downward, which in turn causes the lifting rod 9 to move downward, and also causes the U-shaped frame 10 and the movable column 11 to move downward. The movable column 11 pushes the metal pipe downward, and together with the fixed column 18 and the support wheel 17, it supports the metal pipe, thereby realizing the bending adjustment of the metal pipe. In addition, the protractor 32 on the back of the U-shaped frame 10 allows the operator to intuitively judge the bending degree of the metal pipe, so as to facilitate the adjustment and control of the bending degree of the metal pipe.

[0054] Meanwhile, the protective cover 31 can shield the edge of the protractor 32 to prevent metal pipes from hitting the protractor 32 and scratching the scale during transportation, thus preventing the impact on reading accuracy and improving the protection effect of the protractor 32. When the protractor 32 needs to be disassembled for replacement, the operator can pull the lever 29, which will move the movable block 30. The movable block 30 will then move the insertion rod 24. When the insertion rod 24 moves out of the insertion hole 26, the limitation on the positioning block 23 can be released. At this time, the protractor 32 can be moved so that the positioning block 23 moves out of the positioning groove 22, and the protractor 32 can be removed for replacement, preventing the use of a protractor 32 with unclear scale or damage.
