Description

Technical Field

[0001] This utility model belongs to the technical field of ship pipe processing equipment, specifically a ship pipe bending device. Background Technology

[0002] Ships are vehicles capable of navigating or anchoring in waterways for transportation or operations, and they possess different technical specifications, equipment, and structural forms depending on their intended use. The shipbuilding process requires various pipe fittings, and pipe bending devices are used to bend these fittings to the required angles.

[0003] Existing marine pipe bending devices typically apply pressure to the pipe through a bending element, bending the pipe by applying pressure. However, due to the excessive rigidity at the bend, directly applying pressure to the pipe during bending can easily cause it to break, rendering the pipe unusable and increasing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a bending device for ship pipe fittings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A ship pipe bending device is provided, comprising a processing table, a fixing mechanism fixedly connected to the right side of the top of the processing table, a heating mechanism fixedly connected to the middle of the top of the processing table, transmission mechanisms fixedly connected to both the front and rear sides of the middle of the top of the processing table, a pressing mechanism fixedly connected to the left side of the top of the processing table, a limit post fixedly connected to the top of the processing table, the heating mechanism including a protective shell fixedly connected to the middle of the top of the processing table, a heat insulation layer fixedly connected to the inner side of the protective shell, a heating cylinder fixedly connected to the inside of the protective shell, an induction coil fixedly connected to the inner side of the heating cylinder, support blocks fixedly connected to the upper and lower sides of the left side of the protective shell, a second hydraulic telescopic rod fixedly connected to the inside of the support block, a connecting block fixedly connected to the end of the second hydraulic telescopic rod near the heating cylinder, a rotating motor fixedly connected to the left side of the connecting block, and a rotating wheel fixedly connected to the output end of the rotating motor.

[0006] Optionally, the processing table includes a table body, with a support column fixedly connected to the lower part of the table body, a connecting column fixedly connected between the left and right support columns, and a fixing column fixedly connected between the connecting columns.

[0007] Optionally, the fixing mechanism includes a housing fixedly connected to the right side of the top of the platform. A first hydraulic telescopic rod is fixedly connected to both the front and rear sides inside the housing. A pressure plate is fixedly connected to the inner end of the first hydraulic telescopic rod. A protective pad is fixedly connected to the inner side of the pressure plate. Limiting blocks are fixedly connected to both the left and right sides of the pressure plate. A sliding groove is provided on the inner side of the housing.

[0008] Optionally, the transmission mechanism includes a transmission motor fixedly connected to the front and rear sides of the top center of the platform, the output end of the transmission motor being fixedly connected to a rotating shaft, and the top of the rotating shaft being fixedly connected to a transmission wheel.

[0009] Optionally, the limiting post includes a column fixedly connected to the top of the platform, and a rotating cylinder is movably connected to the outer side of the column.

[0010] Optionally, the extrusion mechanism includes a support fixedly connected to the left side of the top of the platform, a third hydraulic telescopic rod fixedly connected inside the support, a fixing block fixedly connected to the rear end of the third hydraulic telescopic rod, and an extrusion wheel movably connected to the inner side of the fixing block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a heating mechanism that prevents pipes from breaking when bent. In use, the pipe is inserted into the fixing mechanism and then enters the heating mechanism between two transmission mechanisms, placing the bent portion of the pipe inside the heating cylinder. By energizing the induction coil, eddy currents are generated in the pipe. As these currents flow inside the pipe, the pipe's resistance converts electrical energy into heat, rapidly heating the pipe. Simultaneously controlling the two upper and lower hydraulic telescopic rods on the left side of the protective shell allows the two rotating wheels to contact the pipe. Starting the rotating motor causes the wheels to rotate, thus rotating the pipe. This results in more even heating at the bend, reducing the rigidity of the heated pipe and making it easier to bend, while also reducing the risk of breakage. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0023] Reference Figures 1 to 4The present invention will now be described. A ship pipe bending device includes a processing table 1. A fixing mechanism 2 is fixedly connected to the right side of the top of the processing table 1. A heating mechanism 4 is fixedly connected to the middle of the top of the processing table 1. Transmission mechanisms 3 are fixedly connected to both the front and rear sides of the middle of the top of the processing table 1. A pressing mechanism 6 is fixedly connected to the left side of the top of the processing table 1. A limit post 5 is fixedly connected to the top of the processing table 1. The heating mechanism 4 includes a protective shell 401 fixedly connected to the middle of the top of the processing table 1. A heat insulation layer 402 is fixedly connected to the inner side of the protective shell 401 to isolate the heat generated inside the heating mechanism 4. A heating cylinder 403 is fixedly connected inside the protective shell 401. An induction coil 404 is fixedly connected to the inner side of the heating cylinder 403. The induction coil 404 has a spiral structure and is distributed inside the heating cylinder 403. By energizing the induction coil 404, an induced current is generated in the pipe inside it. Support blocks 405 are fixedly connected to the upper and lower sides of the left side of the protective shell 401. A second hydraulic telescopic rod 406 is fixedly connected inside the support block 405. A connecting block 407 is fixedly connected to one end of the second hydraulic telescopic rod 406 near the heating cylinder 403. A rotating motor 409 is fixedly connected to the left side of the connecting block 407. A rotating wheel 408 is fixedly connected to the output end of the rotating motor 409. In use, the pipe is inserted into the fixing mechanism 2 and enters the heating mechanism 4 through the two transmission mechanisms 3, so that the bent part of the pipe is located inside the heating cylinder 403. By energizing the induction coil 404, eddy current is generated in the pipe. When the eddy current flows inside the pipe, the electrical energy is converted into heat energy due to the resistance of the pipe itself, so that the pipe heats up quickly. This allows for rapid heating of the pipe. By simultaneously controlling the two upper and lower second hydraulic telescopic rods 406 on the left side of the protective shell 401, the upper and lower rotating wheels 408 can contact the pipe. By starting the rotating motor 409, the rotating wheels 408 rotate, thus rotating the pipe. This makes the heating of the bent part of the pipe more uniform. The rigidity of the pipe is weakened after heating, making it easier to bend and less prone to breakage.

[0024] Furthermore, the processing table 1 includes a table body 101, with a support column 102 fixedly connected to the lower part of the table body 101, a connecting column 104 fixedly connected between the left and right support columns 102, and a fixing column 103 fixedly connected between the connecting columns 104. The processing table 1 is used to fix the various components of the device.

[0025] Furthermore, the fixing mechanism 2 includes a housing 201 fixedly connected to the top right side of the platform 101. First hydraulic telescopic rods 202 are fixedly connected to both the front and rear sides inside the housing 201. A pressure plate 203 is fixedly connected to the inner end of the first hydraulic telescopic rod 202. A protective pad 204, made of rubber, is fixedly connected to the inner side of the pressure plate 203 to ensure greater stability when pressed against the pipe fitting. Limiting blocks 205 are fixedly connected to both the left and right sides of the pressure plate 203. A sliding groove 206 is provided on the inner side of the housing 201, and the limiting blocks 205... 5 can move in the slide groove 206 to limit and guide the movement of the pressure plate 203; the left and right sides of the outer shell 201 are provided with slots for pipe fittings to pass through. The pipe fittings can be inserted into the outer shell 201 through the slots. After insertion, by simultaneously activating the two first hydraulic telescopic rods 202, the two pressure plates 203 can move closer to the pipe fitting at the same time. As they move closer, the protective pad 204 presses against the outside of the pipe fitting, thereby fixing the pipe fitting. The pipe can be fixed before bending the pipe fitting, thus enabling stable bending of the pipe fitting.

[0026] Furthermore, the transmission mechanism 3 includes a transmission motor 301 fixedly connected to the front and rear sides of the top center of the platform 101. The output end of the transmission motor 301 is fixedly connected to a rotating shaft 302, and the top of the rotating shaft 302 is fixedly connected to a transmission wheel 303. By starting the transmission motor 301, the rotating shaft 302 drives the transmission wheel 303 to rotate, thereby driving the pipe to move. After the bending part of the pipe is heated, the bending part of the pipe can be transmitted to the outside of the limiting post 5 to wait for bending by starting the transmission motor 301.

[0027] Furthermore, the limiting post 5 includes a post 502 fixedly connected to the top of the platform 101. A rotating cylinder 501 is movably connected to the outside of the post 502. The rotating cylinder 501 can rotate outside the post 502. The limiting post 5 is used to limit the pipe fitting, so that the pipe fitting can bend under the pressure of the extrusion mechanism 6 and the blocking effect of the limiting post 5.

[0028] Furthermore, the extrusion mechanism 6 includes a support 601 fixedly connected to the top left side of the platform 101. A third hydraulic telescopic rod 603 is fixedly connected inside the support 601. A fixing block 604 is fixedly connected to the rear end of the third hydraulic telescopic rod 603. An extrusion wheel 602 is movably connected to the inner side of the fixing block 604. The extrusion wheel 602 can rotate inside the fixing block 604. By activating the third hydraulic telescopic rod 603, the fixing block 604 drives the extrusion wheel 602 to extrude the pipe, and the pressure causes the pipe to bend.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
