Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a pipe bending machine for building construction. Background Technology

[0002] Pipes are common building materials in construction projects, often used for water supply, sewage discharge, and wiring installation. In some construction situations, it is necessary to use pipes with curves, which requires the use of a pipe bending machine to bend the pipes.

[0003] Application number CN202420378349.8 discloses a pipe bending machine for building construction, specifically relating to the field of pipe processing. The machine includes a casing with a machine plate fixedly mounted on it. A guide tube is fixedly mounted on the front surface of the machine plate, and a bending motor is fixedly connected to the rear surface of the machine plate. A shaft is fixedly connected to the power output end of the bending motor, and the shaft is rotatably connected to the machine plate, extending to the front surface of the machine plate. An active bending wheel is rotatably connected to the shaft, located below and to the side of the guide tube. A rotating support plate is fixedly connected to the end of the shaft, and a first hydraulic rod is fixedly connected to one end of the rotating support plate. The power output end of the first hydraulic rod is equipped with a bending structure. This invention solves the technical problem that current pipe bending machines require manual removal of the bent pipe material, which reduces bending efficiency and makes it difficult to quickly adjust the bending position of the pipe material, thus affecting the processing requirements.

[0004] However, the guiding structure of this device has a fixed diameter, which means it can only bend pipes of one diameter. Pipes that are too thick cannot pass through the guide tube, while pipes that are too thin will wobble inside, affecting positioning and bending accuracy. This results in poor applicability of the device. Therefore, a pipe bending machine for construction engineering is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a pipe bending machine for building construction, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pipe bending machine for construction engineering includes an operating table. A fixed guide wheel and a bending wheel are rotatably mounted on the top surface of the operating table. A guide groove is provided on the outer side of the fixed guide wheel, and a bending groove is provided on the outer side of the bending wheel. Both the guide groove and the bending groove are used for inserting pipes. The top surface of the operating table is provided with a sliding groove, a first threaded rod is installed inside the sliding groove, a slider is sleeved on the outside of the first threaded rod, the slider is threadedly adapted to the first threaded rod, a movable guide wheel is rotatably installed on the top of the slider, a guide ring is fixedly sleeved on the outside of the movable guide wheel, and the guide groove is adapted to the guide ring.

[0007] By adopting the above technical solution, the movable guide wheel and the fixed guide wheel work together to achieve stable clamping and smooth guidance of the pipe. The bending wheel and the adjustable clamp can adapt to different pipe diameters and are suitable for bending needs of various pipes, making it highly practical.

[0008] Specifically, a slot is provided on one side of the bending wheel. There are two slots, which are used for the two ends of the clamp to be installed and inserted. The clamp is arranged in a C-shape.

[0009] By adopting the above technical solution, the two ends of the C-shaped clamp are inserted into two slots on the side of the bending wheel. The C-shaped opening area and bending groove of the clamp are used to accommodate the pipe. When it is installed in place, the clamp and bending groove can clamp and fix the pipe.

[0010] Specifically, a third threaded rod is installed on one side of the clamp, and one end of the third threaded rod is rotatably connected to one side of the mounting plate.

[0011] By adopting the above technical solution, when the clamp cannot hold a thinner pipe, the third threaded rod can be turned to move the mounting plate into the bending groove, so that the mounting plate can hold the pipe.

[0012] Specifically, rubber pads are fixedly bonded to both the side of the mounting plate away from the third threaded rod and the inner side of the clamp.

[0013] By adopting the above technical solution, the rubber pad increases the friction and prevents the pipe from slipping during clamping. At the same time, its soft material prevents the hard clamp from directly contacting the pipe surface, effectively preventing the pipe from being scratched or indented during clamping and bending.

[0014] Specifically, the top and bottom of the bending wheel are each equipped with a second threaded rod, and the ends of the two second threaded rods that are close to each other are fixedly connected to one side of the pressure plate. The pressure plate is movably installed inside the bending wheel.

[0015] By adopting the above technical solution, tightening the second threaded rod drives the pressure plate to press the clamp in the slot, thereby fixing the clamp.

[0016] Specifically, a motor is fixedly installed at the bottom of the operating table, and the output end of the motor is fixedly connected to the bottom of the bending wheel.

[0017] By adopting the above technical solution, the motor drives the bending wheel to rotate, and the pipe held by the clamp and the bending wheel will be bent by rotating with the bending wheel.

[0018] The beneficial effects of this utility model are: The present invention discloses a pipe bending machine for construction engineering, which achieves stable clamping and smooth guidance of pipes through the cooperation of movable guide wheels and fixed guide wheels. The bending wheels and adjustable clamps can adapt to different pipe diameters and are suitable for bending various types of pipes, making it highly practical. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As one embodiment of this utility model, such as Figures 1-3 As shown, the pipe bending machine for construction engineering of this utility model includes an operating table 1. A fixed guide wheel 6 and a bending wheel 9 are rotatably installed on the top surface of the operating table 1. A guide groove 7 is opened on the outer side of the fixed guide wheel 6, and a bending groove 8 is opened on the outer side of the bending wheel 9. Both the guide groove 7 and the bending groove 8 are used for inserting pipes. The top surface of the operating table 1 is provided with a sliding groove 5. A first threaded rod 4 is installed inside the sliding groove 5. A slider 13 is sleeved on the outside of the first threaded rod 4. The slider 13 is threadedly matched with the first threaded rod 4. A movable guide wheel 2 is rotatably installed on the top of the slider 13. A guide ring 3 is fixedly sleeved on the outside of the movable guide wheel 2. The guide groove 7 is matched with the guide ring 3.

[0023] In use, by turning the first threaded rod 4, the slider 13 is driven to move linearly in the slide groove 5, thereby driving the movable guide wheel 2 to move towards the fixed guide wheel 6, so that the guide ring 3 cooperates with the guide groove 7 to clamp the pipe. Both the movable guide wheel 2 and the fixed guide wheel 6 can rotate, thereby achieving the guiding effect on the pipe.

[0024] The present invention also includes a slot 15 provided on one side of the bending wheel 9. There are two slots 15, which are used for the two ends of the clamp 11 to be installed and inserted. The clamp 11 is arranged in a C-shaped structure.

[0025] When in use, the two ends of the C-shaped clamp 11 are inserted into the two slots 15 on the side of the bending wheel 9. The C-shaped opening area of ​​the clamp 11 and the bending groove 8 are used to accommodate the pipe. When it is installed in place, the clamp 11 and the bending groove 8 can clamp and fix the pipe.

[0026] The present invention also includes a third threaded rod 12 installed on one side of the clamp 11, and one end of the third threaded rod 12 is rotatably connected to one side of the mounting plate 16.

[0027] When the clamp 11 is unable to hold a thinner pipe, the third threaded rod 12 can be turned to move the mounting plate 16 into the bending groove 8 so that the mounting plate 16 can hold the pipe.

[0028] The present invention also includes rubber pads 17 fixedly bonded to both the side of the mounting plate 16 away from the third threaded rod 12 and the inner side of the clamp 11.

[0029] When in use, the rubber pad 17 increases friction to prevent the pipe from slipping during clamping. At the same time, its soft material prevents the hard clamp 11 from directly contacting the pipe surface, effectively preventing the pipe from being scratched or indented during clamping and bending.

[0030] The present invention also includes that the top and bottom ends of the bending wheel 9 are each equipped with a second threaded rod 10, and the ends of the two second threaded rods 10 that are close to each other are fixedly connected to one side of the pressure plate 14, and the pressure plate 14 is movably installed inside the bending wheel 9.

[0031] When in use, tightening the second threaded rod 10 causes the pressure plate 14 to press the clamp 11 in the slot 15, thereby fixing the clamp 11.

[0032] The present invention also includes a motor 18 fixedly installed at the bottom of the operating table 1, and the output end of the motor 18 is fixedly connected to the bottom of the bending wheel 9.

[0033] When in use, the motor 18 drives the bending wheel 9 to rotate, and the pipe held by the clamp 11 and the bending wheel 9 will be bent by rotating with the bending wheel 9.

[0034] In use, the pipe is first passed through the guide groove 7 and placed in the bending groove 8. By turning the first threaded rod 4, the slider 13 moves linearly in the groove 5, thereby moving the movable guide wheel 2 towards the fixed guide wheel 6. This allows the guide ring 3 to cooperate with the guide groove 7 to clamp the pipe. Both the movable guide wheel 2 and the fixed guide wheel 6 can rotate, thus guiding the pipe. Then, the two ends of the clamp 11 are inserted into the two slots 15 until the inner side of the clamp 11 cooperates with the bending groove 8 to clamp the pipe. By tightening the second threaded rod 10, the pressure plate 14 presses the clamp 11 in the slot 15 to fix the clamp 11. Then, the motor 18 is started by connecting an external power source. The motor 18 drives the bending wheel 9 to rotate, and the pipe clamped by the clamp 11 and the bending wheel 9 will rotate with the bending wheel 9 to bend.
