Description

Technical Field

[0001] This utility model relates to the technical field of U-shaped sliding pipe clamps required for fixing pipelines on ships, specifically a marine U-shaped sliding pipe clamp bending device. Background Technology

[0002] In the field of shipbuilding and repair, U-shaped sliding pipe clamps are widely used in various pipeline systems of ships as important pipeline fixing components. The accuracy and efficiency of their bending process directly affect the installation quality and overall performance of the ship's pipeline system.

[0003] The positioning structure design of existing bending devices is relatively simple and difficult to adapt to the bending requirements of pipe clamps of different specifications and models. When bending pipe clamps with different pipe diameters and wall thicknesses is required, it is often necessary to frequently replace positioning components or adjust the device structure. The operation is cumbersome and time-consuming, which seriously affects production efficiency. Some bending devices do not provide sufficient support stability for pipe clamps during the bending process. When pipe clamps are bent under force, they are prone to displacement or deformation, making it difficult to guarantee the bending angle and dimensional accuracy. This not only increases the scrap rate, but may also affect the safety and reliability of the ship's pipeline system due to pipe clamp quality problems. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a marine U-shaped sliding pipe clamp bending device, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a marine U-shaped sliding pipe clamp bending device, including a workbench and a mounting base and a backing plate located on the top of the workbench. A movable frame is provided on the side of the mounting base away from the workbench. A sliding groove is opened at the end of the movable frame away from the mounting base. An adjustment mechanism is slidably connected to the inner surface of the sliding groove. A fixing plate is fixedly installed on the top of the mounting base near the backing plate by bolts. A center positioning block is fixedly installed at the end of the fixing plate near the movable frame.

[0006] The adjustment mechanism includes a connecting plate, a slider that is slidably connected to the slide groove is provided at one end of the connecting plate near the movable frame, an adjustment block is fixedly installed at the end of the slider away from the connecting plate, an eccentric wheel is provided on the side of the adjustment block near the abutment plate, a rotating shaft is provided on the side of the adjustment block near the eccentric wheel, and a groove is provided at the center of the outer surface of the eccentric wheel.

[0007] Preferably, the movable frame has three sets of screw holes evenly spaced at one end near the support plate. A positioning plate is provided on the side of the movable frame near the support plate. A locking screw for fixing the positioning plate is provided on the side of the positioning plate away from the movable frame. A guide plate is fixedly installed on the end of the movable frame near the support plate. A support plate is slidably installed on the inner side of the guide plate. A hydraulic cylinder is provided on the side of the movable frame away from the support plate. A guide column slidably connected to the movable frame is provided on the end of the support plate near the movable frame. A foot switch is provided at the bottom of the workbench. The foot switch is of model YDT1-14.

[0008] Through the above technical solution, by opening screw holes on the mobile frame and cooperating with the positioning plate and locking screws, the position of the positioning plate can be quickly adjusted according to different specifications of pipe clamps, so as to achieve precise positioning and fixing of the pipe clamps. The sliding installation design of the guide plate and the support plate enhances the support stability of the device during the bending process of the pipe clamp, effectively avoids the pipe clamp from shifting during bending, and improves bending accuracy and quality.

[0009] Preferably, the cross-section of the central positioning block is in the shape of a "︹" and the fixing plate is detachably installed on the top of the mounting base by bolts.

[0010] The above technical solution, by setting the cross-section of the central positioning block to be in the shape of a "︹" to prevent the round steel from rebounding after bending, and by fixing the plate to be detachably installed on the top of the mounting base, makes it convenient to replace the central positioning block of different specifications when needed. At the same time, it can be quickly disassembled and installed when the device is maintained, which improves the versatility and maintenance convenience of the device.

[0011] Preferably, the support plate is provided in two identical sets, and the two sets of support plates are symmetrically distributed on the movable frame, and the cross-section of the support plate is "L" shaped.

[0012] By using the above technical solution, and by setting the support plate in an "L" shape, it is convenient to place the pipe clamp on top of the support plate before bending. During the bending process, the pipe clamp is kept under uniform force, which effectively prevents the pipe clamp from deforming due to uneven force during bending, and further ensures the consistency and accuracy of the bending effect.

[0013] Preferably, the adjustment mechanism further includes a locking screw, a bidirectional screw, and a handwheel. The locking screw is provided on the side of the connecting plate away from the connecting plate. The inner side of the adjustment block is provided with a bidirectional screw that is rotatably connected to the moving frame. A handwheel is fixedly installed at one end of the bidirectional screw.

[0014] The above technical solution incorporates an adjustment mechanism, allowing workers to easily adjust the spacing of the adjustment blocks according to pipe clamps of varying sizes. This improves the processing efficiency of U-shaped sliding pipe clamps and enhances the production quality of the pipe clamps.

[0015] Preferably, the groove has a "C" shaped cross-section, and the eccentric wheel is mounted on the rotating shaft via a bearing.

[0016] With the above technical solution, by setting the groove cross-section to be "C" shaped, when the bending work begins, the round steel to be made is placed on the support plate and embedded in the groove. The rim of the eccentric wheel has a groove that can lock the round steel, so that it will not move during the bending process. The eccentric wheel is mounted on the rotating shaft through a bearing, which reduces the frictional resistance when the eccentric wheel rotates, thereby extending the service life of the device.

[0017] Preferably, the adjusting blocks are provided in two identical sets, the two sets of adjusting blocks are symmetrically distributed on the movable frame, and both sets of adjusting blocks are threadedly connected to the bidirectional screw.

[0018] Through the above technical solution, two sets of symmetrically distributed adjusting blocks connected to the bidirectional screw can move synchronously during the adjustment process. The operator only needs to turn the handwheel to drive the bidirectional screw to rotate, so as to realize the synchronous adjustment of the two adjusting blocks, which further improves the adjustment efficiency and the convenience of operation.

[0019] Compared with the prior art, this utility model provides a marine U-shaped sliding pipe clamp bending device, which has the following advantages:

[0020] 1. This shipboard U-shaped sliding pipe clamp bending device uses two sets of symmetrically distributed adjusting blocks threaded to a bidirectional screw. These blocks can move synchronously during adjustment. The operator only needs to turn the handwheel to rotate the bidirectional screw to achieve synchronous adjustment of the two adjusting blocks, further improving adjustment efficiency and ease of operation. It allows workers to adjust the spacing of the adjusting blocks according to pipe clamps of different sizes, improving the processing efficiency of the U-shaped sliding pipe clamp and the production quality of the pipe clamp. The groove with a "C" shaped structure can tightly wrap the pipe clamp, preventing it from moving during bending.

[0021] 2. The ship's U-shaped sliding pipe clamp bending device has a central positioning block with a cross-section of "︹" to prevent the round steel from rebounding after bending. It can be detachably installed on the top of the mounting base via a fixing plate, which makes it convenient to replace the central positioning block of different specifications when needed. At the same time, it can be quickly disassembled and installed when the device is maintained, which improves the versatility and maintenance convenience of the device. Attached Figure Description

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.

[0029] Example 1: As Figure 1-5 As shown, the present invention provides a marine U-shaped sliding pipe clamp bending device, including a workbench 1, a mounting base 2, and a backing plate 3 located on the top of the workbench 1. A movable frame 4 is provided on the side of the mounting base 2 away from the workbench 1. A sliding groove 5 is provided at the end of the movable frame 4 away from the mounting base 2. An adjustment mechanism 6 is slidably connected to the inner surface of the sliding groove 5. A fixing plate 12 is fixedly installed on the top of the mounting base 2 near the backing plate 3 by bolts. A center positioning block 13 is fixedly installed at the end of the fixing plate 12 near the movable frame 4. A hydraulic cylinder 14 is provided on the side of the movable frame 4 away from the backing plate 3. A guide column 15 is slidably connected to the movable frame 4 at the end of the backing plate 3 near the movable frame 4.

[0030] The adjustment mechanism 6 includes a connecting plate 601. A slider 602 that is slidably connected to the slide groove 5 is provided at one end of the connecting plate 601 near the movable frame 4. An adjustment block 604 is fixedly installed at the other end of the slider 602 away from the connecting plate 601. An eccentric wheel 605 is provided on the side of the adjustment block 604 near the abutment plate 3. A rotating shaft 606 is provided on the side of the adjustment block 604 near the eccentric wheel 605. A groove 607 is provided at the center of the outer surface of the eccentric wheel 605.

[0031] Specifically, the movable frame 4 has three sets of screw holes 7 at equal intervals at one end near the support plate 3. A positioning plate 8 is provided on the side of the movable frame 4 near the support plate 3. A locking screw 9 for fixing the positioning plate 8 is provided on the side of the positioning plate 8 away from the movable frame 4. A guide plate 10 is fixedly installed on the side of the movable frame 4 near the support plate 3. A support plate 11 is slidably installed on the inner side of the guide plate 10. A hydraulic cylinder 14 is provided on the side of the movable frame 4 away from the support plate 3. A guide column 15 that is slidably connected to the movable frame 4 is provided on the side of the support plate 3 near the movable frame 4. A foot switch is provided at the bottom of the workbench 1. The foot switch is of model YDT1-14. The advantages are that by opening screw holes 7 on the movable frame 4, and cooperating with positioning plate 8 and locking screw 9, the position of positioning plate 8 can be quickly adjusted according to different specifications of pipe clamps, so as to achieve precise positioning and fixing of pipe clamps. The sliding installation design of guide plate 10 and support plate 11 enhances the support stability of the device during the bending process of pipe clamps, effectively avoids the pipe clamps from shifting during bending, and improves bending accuracy and quality.

[0032] Specifically, the cross-section of the center positioning block 13 is in the shape of a "︹" and the fixing plate 12 is detachably installed on the top of the mounting base 2 by bolts. The advantages are that by setting the cross-section of the center positioning block 13 to a "︹" shape, it prevents the round steel from rebounding after bending. The detachable installation of the fixing plate 12 on the top of the mounting base 2 facilitates quick disassembly and installation when different specifications of the center positioning block 13 need to be replaced, and when the device needs maintenance, thus improving the versatility and ease of maintenance of the device.

[0033] Specifically, two identical sets of support plates 11 are provided, symmetrically distributed on the movable frame 4, with each support plate 11 having an "L"-shaped cross-section. The advantage is that by arranging the support plates 11 in an "L" shape, it is convenient to place the pipe clamp on top of the support plate 11 before bending, and during bending, the pipe clamp is kept under uniform force, effectively preventing deformation due to uneven force during bending, further ensuring the consistency and accuracy of the bending effect.

[0034] Example 2:

[0035] like Figure 2-5As shown, as an improvement on the previous embodiment, bending of pipe clamps of different sizes is achieved. Specifically, the adjusting mechanism 6 also includes a locking screw 603, a bidirectional screw 608, and a handwheel 609. The locking screw 603 is provided on the side of the connecting plate 601 away from the connecting plate 601. The bidirectional screw 608, which is rotatably connected to the moving frame 4, is provided on the inner side of the adjusting block 604. A handwheel 609 is fixedly installed at one end of the bidirectional screw 608. The advantage is that the adjusting mechanism 6 allows workers to easily adjust the spacing of the adjusting block 604 according to pipe clamps of different sizes, improving the processing efficiency of the U-shaped sliding pipe clamp and the production quality of the pipe clamp.

[0036] Specifically, the groove 607 has a C-shaped cross-section, and the eccentric wheel 605 is mounted on the rotating shaft 606 via a bearing. The advantage is that by setting the groove 607 to a C-shaped cross-section, when the bending process begins, the round steel to be manufactured is placed on the support plate 11 and embedded in the groove 607. The groove 607 at the rim of the eccentric wheel 605 can hold the round steel in place, preventing it from moving during bending. The eccentric wheel 605 is mounted on the rotating shaft 606 via a bearing, reducing the frictional resistance during rotation and thus extending the service life of the device.

[0037] Specifically, two identical sets of adjusting blocks 604 are provided, symmetrically distributed on the movable frame 4. Both sets of adjusting blocks 604 are threadedly connected to the bidirectional screw 608. The advantage is that, through the two symmetrically distributed adjusting blocks 604 threadedly connected to the bidirectional screw 608, they can move synchronously during adjustment. The operator only needs to turn the handwheel 609 to rotate the bidirectional screw 608, thus achieving synchronous adjustment of the two adjusting blocks 604, further improving adjustment efficiency and operational convenience.

[0038] Working principle: During use, the round steel to be manufactured is placed on the support plate 11 and embedded in the groove 607. The groove 607 on the rim of the eccentric wheel 605 can hold the round steel in place, preventing it from moving during bending. The eccentric wheel 605 is mounted on the rotating shaft 606 via bearings, reducing the frictional resistance when the eccentric wheel 605 rotates, thereby extending the service life of the device. At this time, the hydraulic cylinder 14 is activated, which pushes the two eccentric wheels 605 on both sides of the device forward along the two sides of the central positioning block 13. When it advances to a certain position, it automatically stops when it hits the limit switch. This prevents the pipe clamp from becoming inward-pointing due to excessive travel, and also prevents it from reversing when the foot is pressed. The switch and hydraulic cylinder 14 drive the two eccentric wheels 605 on both sides of the device to return to their original positions. At this time, a standard U-shaped pipe clamp can be made. Through two sets of symmetrically distributed adjusting blocks 604 threadedly connected to the bidirectional screw 608, they can move synchronously during the adjustment process. The operator only needs to turn the handwheel 609 to drive the bidirectional screw 608 to rotate, so as to realize the synchronous adjustment of the two adjusting blocks 604, which further improves the adjustment efficiency and the convenience of operation. It is convenient for the staff to adjust the spacing of the adjusting blocks 604 according to the pipe clamps of different sizes, improve the processing efficiency of U-shaped sliding pipe clamps, and improve the production quality of pipe clamps. By setting the cross section of the center positioning block 13 to be in the shape of a "︹" to prevent the round steel from rebounding after bending, it can be detachably installed on the top of the mounting base 2 through the fixing plate 12. It is convenient to quickly disassemble and install when it is necessary to replace the center positioning block 13 of different specifications, and when the device is maintained, which improves the versatility and maintenance convenience of the device.
