Description

Technical Field

[0001] This utility model relates to the field of pipe forming technology, specifically to a stainless steel thin-walled pipe bending and forming equipment with a positioning mechanism. Background Technology

[0002] Pipe bending and forming equipment usually refers to pipe bending machines, which are devices used for bending pipes. They can bend pipes into various shapes to meet the needs of different fields. Based on the operation method and technical characteristics, pipe bending machines can be roughly divided into several types, such as CNC pipe bending machines and hydraulic pipe bending machines.

[0003] Existing patent application number CN201921680404.4 discloses a tube forming device for precision hardware product manufacturing. This utility model relates to the technical field of tube production equipment and discloses a tube forming device for precision hardware product manufacturing, including a worktable. This tube forming device allows the left side of a steel pipe to be placed inside a U-shaped limiting plate. Releasing the hand lever resets the compression spring, moving the rear side of the hand lever into a groove. This activates the electric push rod, causing the connecting plate and U-shaped extrusion block to rotate downwards, bending the steel pipe. Because the rear wall of the U-shaped limiting plate has three grooves, the distance between the hand lever and the bottom wall of the U-shaped limiting plate can be adjusted according to the different diameters of the steel pipe to measure the required bending position, improving bending accuracy. This makes the entire forming device easy to operate when fixing the steel pipe and allows for adjustment of the fixing range according to different steel pipe specifications, achieving the effects of user convenience and improved forming efficiency.

[0004] This device primarily relies on a U-shaped limiting plate and a hand lever to position the steel pipe. However, this positioning method may not be suitable for all types of steel pipes or all bending requirements. For some special shapes or sizes of steel pipes, a more complex positioning mechanism may be needed to ensure bending accuracy.

[0005] Therefore, we propose a stainless steel thin-walled tube bending and forming device with a positioning mechanism to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a stainless steel thin-walled tube bending and forming device with a positioning mechanism, to solve the problem that existing devices in the background art mainly rely on U-shaped limiting plates and hand levers to achieve steel tube positioning. However, this positioning method may not be suitable for all types of steel tubes or all bending requirements. For some special shapes or sizes of steel tubes, a more complex positioning mechanism may be needed to ensure bending accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel thin-walled tube bending and forming device with a positioning mechanism, comprising an operating table, a bracket fixedly connected to the top of the operating table, a motor installed inside the operating table, a bending disc connected to the output end of the motor, a bidirectional lead screw rotatably connected inside the operating table, a drive motor connected to one end of the bidirectional lead screw, a threaded block threadedly connected to the outer surface of the bidirectional lead screw, a clamping block fixedly connected to the top of the threaded block, a tube body fitted against the inner wall of the clamping block, a fixing plate fixedly connected to the left side of the top of the operating table, a threaded rod threadedly connected to the inside of the fixing plate, and a guide block connected to the right side of the threaded rod via a bearing.

[0008] Preferably, the fixed plate has a sliding connection to a limiting rod inside, and the limiting rod is fixedly connected to the guide block.

[0009] By adopting the above technical solution, the movement of the guide block can drive the limiting rod to slide along the fixed plate, ensuring stability during the movement process.

[0010] Preferably, one end of the operating table is fixedly connected to a mounting plate, and an electric push rod is mounted on the top of the mounting plate. One end of the electric push rod is connected to a fixed frame, and a hydraulic cylinder is installed inside the fixed frame.

[0011] Using the above technical solution, by activating the electric push rod, the output end of the electric push rod can push the fixed frame and the hydraulic cylinder to move.

[0012] Preferably, both sides of the fixed frame are fixedly connected to connecting sleeves, and the connecting sleeves are slidably connected to clamping rods.

[0013] Preferably, the output end of the hydraulic cylinder is connected to a connecting block, and a support rod is hinged between the clamping rod and the connecting block.

[0014] Preferably, a cylinder is mounted on the top of the bracket, and a support plate is fixedly connected to the bottom of the cylinder.

[0015] Preferably, a spring telescopic rod is fixedly connected to the bottom of the support plate, and a compression plate is fixedly connected to the bottom of the spring telescopic rod.

[0016] By adopting the above technical solution, the support plate can be moved by starting the cylinder. At the same time, the spring telescopic rod and the extrusion plate under the support plate also descend. When the extrusion plate contacts the pipe body, it can prevent the pipe body from shifting during bending.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the stainless steel thin-walled tube bending and forming equipment with a positioning mechanism;

[0018] 1. The device consists of a bending disc, a two-way lead screw, a drive motor, a threaded block, a clamping block, a pipe body, a fixing plate, a threaded rod, and a guide block. When the drive motor drives the two-way lead screw to rotate, the threaded block moves on the lead screw, thereby moving the clamping block. The inner wall of the clamping block is tightly fitted with the pipe body to fix the pipe during bending and prevent it from sliding or deforming. The output end of the motor is connected to the bending disc. By rotating the motor, the bending disc can bend the pipe, and rotating the threaded rod can drive the guide block to move, thereby pushing and guiding the direction of the pipe during bending. This can provide a positioning and guiding effect for the pipe during bending.

[0019] 2. With the guide block and limit rod set, the guide block can drive the limit rod to slide along the fixed plate when it moves, thereby ensuring the stability of the guide block during the movement process;

[0020] 3. By activating the hydraulic cylinder, clamping rod, connecting block, and support rod, the connecting block, support rod, and clamping rod can be moved to clamp or release the pipe.

[0021] 4. With the electric push rod and fixed frame in place, when the clamping rod releases the pipe, the electric push rod is activated, which can push the fixed frame and the pipe to move, thereby achieving the purpose of automatic feeding.

[0022] 5. Through the cylinder, support plate, spring telescopic rod and extrusion plate, the cylinder can push the support plate and the spring telescopic rod and extrusion plate below it to move downward, so as to press the pipe during the bending process to ensure the stability and accuracy of its bending shape.

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.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a stainless steel thin-walled tube bending and forming device with a positioning mechanism, including an operating table 1, a bracket 2 fixedly connected to the top of the operating table 1, a motor 3 installed inside the operating table 1, a bending disc 4 connected to the output end of the motor 3, a bidirectional lead screw 5 rotatably connected inside the operating table 1, a drive motor 6 connected to one end of the bidirectional lead screw 5, a threaded block 7 threadedly connected to the outer surface of the bidirectional lead screw 5, a clamping block 8 fixedly connected to the top of the threaded block 7, and a tube body 9 fitted to the inner wall of the clamping block 8, a fixing plate 10 fixedly connected to the left side of the top of the operating table 1, a threaded rod 11 threadedly connected to the inside of the fixing plate 10, and a guide block 12 connected to the right side of the threaded rod 11 via a bearing, the fixing plate 1... The internal sliding connection of the 0 is limited by the limit rod 13, and the limit rod 13 is fixedly connected to the guide block 12. When the drive motor 6 drives the bidirectional lead screw 5 to rotate, the threaded block 7 will move on the bidirectional lead screw 5, thereby realizing the movement of the clamping block 8. The inner wall of the clamping block 8 is tightly fitted with the pipe body 9, which is used to fix the pipe during the bending process and prevent it from sliding or deforming. The output end of the motor 3 is connected to the bending disc 4. By rotating the motor 3, the bending disc 4 can bend the pipe, and rotating the threaded rod 11 can drive the guide block 12 to move. When the guide block 12 moves, it can drive the limit rod 13 to slide along the fixed plate 10 to ensure the stability during the movement, thereby pushing and guiding the direction of the pipe during the bending process, which can play a positioning and guiding role when the pipe is bent.

[0032] One end of the operating table 1 is fixedly connected to a mounting plate 14, and an electric push rod 15 is mounted on the top of the mounting plate 14. One end of the electric push rod 15 is connected to a fixed frame 16, and a hydraulic cylinder 17 is installed inside the fixed frame 16. Connecting sleeves 18 are fixedly connected to both sides of the fixed frame 16, and clamping rods 19 are slidably connected inside the connecting sleeves 18. The output end of the hydraulic cylinder 17 is connected to a connecting block 20, and a support rod 21 is hinged between the clamping rod 19 and the connecting block 20. A cylinder 22 is mounted on the top of the bracket 2, and a support plate 23 is fixedly connected to the bottom of the cylinder 22. A spring telescopic rod 24 is fixedly connected to the bottom of the support plate 23, and the spring telescopic rod 24... The bottom of the retracting rod 24 is fixedly connected to the extrusion plate 25. Activating the hydraulic cylinder 17 can push the connecting block 20, support rod 21, and clamping rod 19 to move, thereby clamping or releasing the pipe. When the clamping rod 19 clamps the pipe body 9, the electric push rod 15 is activated, which can push the fixed frame 16 and the pipe body 9 to move, thereby achieving automatic feeding. When the pipe body 9 is being bent, the cylinder 22 is activated, which can push the support plate 23 and the spring telescopic rod 24 and extrusion plate 25 below it to move downwards, thereby pressing the pipe during the bending process to ensure the stability and accuracy of its bending shape.

[0033] Working principle: When using the stainless steel thin-walled tube bending and forming equipment with a positioning mechanism, firstly, the hydraulic cylinder 17 is activated, which pushes the connecting block 20, support rod 21, and clamping rod 19 to move, thereby clamping the tube body 9. Then, the electric push rod 15 is activated, which pushes the fixed frame 16 and the tube to move for automatic feeding. When the drive motor 6 drives the bidirectional lead screw 5 to rotate, the threaded block 7 moves on the bidirectional lead screw 5, thereby moving the clamping block 8. The inner wall of the clamping block 8 is tightly fitted with the tube body 9, used for bending during the bending process. The pipe is fixed to prevent it from sliding or deforming. The output end of the motor 3 is connected to the bending disc 4. By rotating the motor 3, the bending disc 4 can bend the pipe. Rotating the threaded rod 11 can drive the guide block 12 to move, thereby pushing and guiding the direction of the pipe during the bending process. This can play a positioning and guiding role when bending the pipe. At the same time, starting the cylinder 22 can push the support plate 23 and the spring telescopic rod 24 and the pressing plate 25 below it to move downward, which is used to press the pipe during the bending process to ensure the stability and accuracy of its bending shape.
