Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a bending device for shipbuilding with an adjustable bending angle. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations, and vary in technical performance, equipment, and structural type according to different usage requirements. In shipbuilding, the layout of piping systems is often very complex, requiring a large amount of bent pipe to construct. These pipes not only need to meet specific bending angle and radius requirements, but also need to possess high strength and corrosion resistance. Therefore, shipbuilding places high demands on pipe bending equipment, requiring it to efficiently and accurately complete the bending process of pipes.

[0003] Chinese patent document CN216857998U discloses a pipe bending device for shipbuilding, including a frame, a cylinder, a connecting sleeve, a mounting plate, a slide rod, and a sliding plate. The cylinder pushes the mounting plate to move, which in turn moves the sliding plate, which in turn causes the guide wheel to move the pipe and make contact with the heating tube, thereby bending the pipe and making the pipe bending operation convenient.

[0004] The aforementioned patent document describes a method of bending and shaping tubing by using the driving force of a cylinder to move a guide wheel. However, this patent document fails to consider the limited precision of the cylinder's driving force, making it difficult to accurately control the bending angle of the tubing. Therefore, in practical applications, this may lead to significant errors in the bending angle, affecting the product's processing accuracy and overall quality. Utility Model Content

[0005] To address the aforementioned problems, a pipe bending device for shipbuilding with adjustable bending angle is provided. By using a movable slider located at the bottom of the guide wheel and a limiting component for restricting the movement of the movable slider, the technical problem of accurately controlling the bending angle of the pipe body is solved.

[0006] To address the problems of existing technologies, this utility model provides an adjustable bending angle pipe bending device for shipbuilding, comprising a worktable, a side plate on the top of the worktable, a linear actuator on one side of the side plate, a guide wheel at the working end of the linear actuator, a heating column on the top of the worktable containing a heating wire, a heater at the bottom of the worktable connected to the heating wire, a movable frame on the worktable, a threaded drive component on the worktable for driving the movable frame, a rotating ring rotatably disposed within the movable frame, a clamping assembly for fixing the pipe body within the rotating ring, a rotating component on one side of the movable frame for driving the fixed pipe body to rotate, an angle adjustment component on the top of the worktable near the guide wheel, the angle adjustment component including a movable slider at the bottom of the guide wheel and a limiting component for limiting the travel of the movable slider, a first threaded rod threadedly connected to the side plate near the linear actuator, a turntable at one end of the first threaded rod and a pressure block at the other end of the first threaded rod.

[0007] Preferably, the limiting component includes a fixed plate; a limiting groove is formed on the top of the worktable, the movable slider is slidably disposed in the limiting groove, a limiting block is also slidably disposed in the limiting groove, the fixed plate is disposed on the worktable on one side of the limiting groove, a second threaded rod is threadedly connected to the fixed plate, a first knob is provided at one end of the second threaded rod, a movable block is provided at the other end of the second threaded rod, the bottom of the movable block is connected to the top of the limiting block, and an angle scale is provided on the outer side of the heating column.

[0008] Preferably, guide rods are slidably disposed on both sides of the second threaded rod on the fixing plate, and one end of the guide rod is connected to one side of the moving block.

[0009] Preferably, the clamping assembly includes a fourth threaded rod, a second knob, and a clamping block;

[0010] Two fourth threaded rods are provided and are symmetrically threaded onto the rotating ring; the second knob is provided at one end of the fourth threaded rod; the clamping block is provided at the other end of the fourth threaded rod; and the rotating ring is provided with smooth rods on both sides of the fourth threaded rod, one end of which is connected to the clamping block.

[0011] Preferably, the rotating assembly includes an extension ring and an extension block; the extension ring is disposed on one side of the rotating ring, and a first gear is disposed on the extension ring; the extension block is disposed on one side of the movable frame, and a second motor is disposed on one side of the movable frame, and a second gear is disposed at the output end of the second motor, the second gear meshing with the first gear.

[0012] Preferably, the threaded drive component includes a third threaded rod; a rectangular slot is provided on the worktable, the third threaded rod is disposed in the rectangular slot, a first motor is provided at one end of the worktable, the output end of the first motor is connected to the third threaded rod, a drive block is also provided on the third threaded rod, and the top of the drive block is connected to the bottom of the moving frame.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. By rotating the first knob, the second threaded rod rotates, thereby moving the moving block along the fixed plate. Since the moving block is connected to the limiting block, it will cause the limiting block to slide within the limiting groove. The position of the limiting block is determined by the angle scale calibration value according to the required bending angle. When the working end of the linear actuator pushes the guide wheel to apply pressure to the tube body, the guide wheel will drive the moving slider to move within the limiting groove. When the moving slider encounters the limiting block, the movement of the moving slider will stop, thereby ensuring that the bending angle is within the predetermined range and avoiding excessive or insufficient bending.

[0015] 2. By starting the second motor, the second gear begins to rotate. Since the second gear meshes with the first gear, its rotation drives the first gear to rotate. The rotation of the first gear drives the extension ring to rotate, which in turn drives the rotating ring to rotate within the moving frame. This ensures that the tube is heated evenly when it is in contact with the heating column, preventing uneven heating of the tube, which can lead to breakage when the tube is bent due to its high rigidity.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1 to 7 As shown, this utility model provides a pipe bending device for shipbuilding with adjustable bending angle, including a workbench 1, a side plate 2 on the top of the workbench 1, a linear actuator 3 on one side of the side plate 2, a guide wheel 4 at the working end of the linear actuator 3, a heating column 5 on the top of the workbench 1, a heating wire 52 inside the heating column 5, a heater 51 at the bottom of the workbench 1 connected to the heating wire 52, a movable frame 6 on the workbench 1, a threaded drive component on the workbench 1 for driving the movable frame 6 to move, and a rotating mechanism rotatably mounted inside the movable frame 6. The rotating ring 7 is equipped with a clamping assembly 8 for fixing the tube body. The moving frame 6 is also equipped with a rotating assembly 10 for driving the fixed tube body to rotate. The top of the worktable 1 is also equipped with an angle adjustment assembly 9 located on one side of the guide wheel 4. The angle adjustment assembly 9 includes a moving slider 91 located at the bottom of the guide wheel 4 and a limiting component for limiting the movement stroke of the moving slider 91. The side plate 2 is threadedly connected to the linear driver 3 on one side. One end of the first threaded rod 11 is equipped with a turntable 12, and the other end of the first threaded rod 11 is equipped with a pressure block 13.

[0026] The tube to be bent is passed through the rotating ring 7 within the moving frame 6 and secured by the clamping assembly 8 on the rotating ring 7, ensuring that the tube will not fall off or move during bending. The tube's position is then adjusted by the threaded drive component, bringing it into contact with the heating column 5. Next, the rotating turntable 12 drives the first threaded rod 11 axially, which in turn moves the pressure block 13 towards the tube, pressing it against the heating column 5. Then, the heater 51 at the bottom of the worktable 1 is activated, heating the heating column 5 via the heating wire 52, preheating the tube directly to facilitate subsequent bending. The rotating assembly 10 is then activated, driving the secured tube to rotate, ensuring even heating and preventing uneven heating that could lead to breakage during bending. Before bending, the guide wheel 4's travel is adjusted by the limiting component according to the desired bending angle, ensuring the bending angle remains within a predetermined range and preventing over- or under-bending. Once the tube body is preheated and the angle is adjusted, start the linear actuator 3. The linear actuator 3 is a push cylinder. The working end of the linear actuator 3 pushes the guide wheel 4 to apply pressure to the tube body, causing the tube body to begin to bend. When the tube body bends to the predetermined angle, the linear actuator 3 will stop moving, completing the bending of the tube body.

[0027] See Figures 1 to 4 As shown, the limiting component includes a fixed plate 94; a limiting groove 92 is provided on the top of the worktable 1, the movable slider 91 is slidably disposed in the limiting groove 92, and a limiting block 93 is also slidably disposed in the limiting groove 92. The fixed plate 94 is disposed on the worktable 1 on one side of the limiting groove 92. A second threaded rod 95 is threadedly connected to the fixed plate 94. A first knob 96 is provided at one end of the second threaded rod 95, and a movable block 97 is provided at the other end of the second threaded rod 95. The bottom of the movable block 97 is connected to the top of the limiting block 93. An angle scale 98 is provided on the outer side of the heating column 5.

[0028] Rotating the first knob 96 causes the second threaded rod 95 to rotate, thereby moving the moving block 97 along the fixed plate 94. Since the moving block 97 is connected to the limiting block 93, it causes the limiting block 93 to slide within the limiting groove 92. The position of the limiting block 93 is determined by the calibrated value on the angle dial 98 according to the required bending angle. When the working end of the linear actuator 3 pushes the guide wheel 4 to apply pressure to the tube body, the guide wheel 4 causes the moving slider 91 to move within the limiting groove 92. When the moving slider 91 encounters the limiting block 93, the movement of the moving slider 91 stops, thereby ensuring that the bending angle is within the predetermined range and avoiding over-bending or under-bending.

[0029] See Figure 4As shown, guide rods 99 are slidably arranged on both sides of the second threaded rod 95 on the fixed plate 94, and one end of the guide rod 99 is connected to one side of the moving block 97.

[0030] When the second threaded rod 95 drives the moving block 97 to move, the moving block 97 will drive the guide rod 99 to slide on the fixed plate 94, thereby improving the stability of the moving block 97.

[0031] See Figure 5 and Figure 6 As shown, the clamping assembly 8 includes a fourth threaded rod 81, a second knob 82, and a clamping block 83; there are two fourth threaded rods 81, which are symmetrically threaded onto the rotating ring 7; the second knob 82 is located at one end of the fourth threaded rod 81; the clamping block 83 is located at the other end of the fourth threaded rod 81, and there are smooth rods 84 on both sides of the rotating ring 7 located on the fourth threaded rod 81, with one end of the smooth rod 84 connected to the clamping block 83.

[0032] By passing the tube to be bent through the rotating ring 7 inside the moving frame 6, the second knob 82 is rotated, causing the fourth threaded rod 81 to rotate on the rotating ring 7. The fourth threaded rod 81 moves the clamping block 83 along the axial direction of the rotating ring 7 until it gradually approaches and contacts the tube. Then, the second knob 82 is rotated until the clamping block 83 is in tight contact with the tube, thus fixing the tube and ensuring that the tube will not fall off or move during the bending process.

[0033] See Figure 7 As shown, the rotating assembly 10 includes an extension ring 101 and an extension block 103; the extension ring 101 is disposed on one side of the rotating ring 7, and a first gear 102 is disposed on the extension ring 101; the extension block 103 is disposed on one side of the movable frame 6, and a second motor 104 is disposed on one side of the movable frame 6, and a second gear 105 is disposed at the output end of the second motor 104, and the second gear 105 meshes with the first gear 102.

[0034] By activating the second motor 104, the second motor 104 drives the second gear 105 to rotate. Since the second gear 105 meshes with the first gear 102, the rotation of the second gear 105 drives the first gear 102 to rotate. The rotation of the first gear 102 drives the extension ring 101 to rotate. The extension ring 101 drives the rotating ring 7 to rotate within the moving frame 6, thereby ensuring that the tube body is heated evenly when it is in contact with the heating column 5. This avoids the situation where the tube body is not heated evenly, and the rigid parts are too rigid, making it easy to break when the tube body is bent.

[0035] See Figure 5As shown, the thread drive component includes a third threaded rod 61; a rectangular slot is provided on the worktable 1, the third threaded rod 61 is disposed in the rectangular slot, a first motor 62 is provided at one end of the worktable 1, the output end of the first motor 62 is connected to the third threaded rod 61, and a drive block 63 is also provided on the third threaded rod 61, the top of the drive block 63 is connected to the bottom of the moving frame 6.

[0036] When it is necessary to adjust the position of the movable frame 6 according to the size of the tube, the first motor 62 is started, and the first motor 62 drives the third threaded rod 61 to rotate. The rotation of the third threaded rod 61 drives the drive block 63 to move, thereby driving the movable frame 6 to move.

[0037] The tube to be bent is passed through the rotating ring 7 inside the moving frame 6 and fixed by the clamping assembly 8 on the rotating ring 7, ensuring that the tube will not fall off or move during bending. Then, the position of the tube is adjusted by the threaded drive component so that the tube contacts the heating column 5. Next, the first threaded rod 11 is driven axially by the rotating turntable 12, which moves the pressure block 13 towards the tube, pressing the tube against the heating column 5. Then, the heater 51 at the bottom of the worktable 1 is activated, heating the heating column 5 through the heating wire 52, preheating the tube for subsequent bending operations. The rotating assembly 10 is then activated, driving the fixed tube to rotate, ensuring uniform heating and preventing uneven heating that could lead to breakage during bending. Before bending, the second threaded rod 95 is rotated by rotating the first knob 96, which in turn moves the moving block 97 along the fixed plate 94. Since the moving block 97 is connected to the limiting block 93, it will cause the limiting block 93 to slide within the limiting groove 92. The position of the limiting block 93 is determined by the calibrated value of the angle dial 98 according to the required bending angle. When the working end of the linear actuator 3 pushes the guide wheel 4 to apply pressure to the tube body, the guide wheel 4 will drive the moving slider 91 to move within the limiting groove 92. When the moving slider 91 encounters the limiting block 93, the movement of the moving slider 91 will stop, thereby ensuring that the bending angle is within the predetermined range and avoiding excessive or insufficient bending.

[0038] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
