Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a pipe bending machine used in construction projects:

[0027] A pipe bending machine for construction projects includes: a horizontal plate 1, a housing 2, a heating block 3, a cavity 4, a first conduit 5, a conveying rail 6, a support leg 7, an electric push rod 8, a clamping block 9, a support plate 10, a turntable 11, a bracket 12, a servo motor 13, a gas tank 14, a small fan 15, a second conduit 16, and a lighter 17. The top of the horizontal plate 1 is fixedly connected to the rectangular housing 2. The inner wall of the housing 2 is fixedly connected to the gas tank 14. The output end of the gas tank 14 is connected to the first conduit 5, and one side of the outer wall of the first conduit 5 penetrates the inner wall of the housing 2. The end of the first conduit 5 is connected to the heating block 3, which is fixedly connected to the top of the horizontal plate 1. The heating block 3 has a cavity 4 machined inside. One side of the heating block 3... The first conduit 5 is connected to the second conduit 16, and the end of the second conduit 16 is connected to a small fan 15 fixedly connected to the lower side of the outer wall of the box 2. An igniter 17 is fixedly connected to the inner wall of the heating block 3. The models of the small fan 15 and the igniter 17 are not limited, as long as they meet the usage requirements. The gas tank 14 stores combustible gas inside, and the type of combustible gas is not limited, as long as it meets the usage requirements. When preheating the pipe, the first conduit 5 is opened, and the combustible gas inside the gas tank 14 can be delivered to the inside of the cavity 4. At the same time, the small fan 15 is turned on, and oxygen can be added to the inside of the cavity 4. Then, the combustible gas can be ignited by the igniter 17 to preheat the pipe.

[0028] The top of the horizontal plate 1 is fixedly connected to the support leg 7, and the top of the horizontal plate 1 is fixedly connected to the conveyor rail 6; the worker can insert the pipe into the inside of the conveyor rail 6, and then the worker can directionally convey the pipe through the conveyor rail 6.

[0029] The inside of the conveyor rail 6 is an arc-shaped concave surface. The top of the box 2 is connected to a cover door by a hinge. The inner wall of the first conduit 5 is connected to a control valve. The operator can open the cover door to disassemble and replace the gas tank 14 inside the box 2. The control valve can change the usage status of the first conduit 5 and also adjust the gas delivery volume.

[0030] A bracket 12 is fixedly connected to the bottom of the horizontal plate 1, and a servo motor 13 is fixedly connected to the top of the bracket 12. A turntable 11 is fixedly connected to the output end of the servo motor 13, and the turntable 11 is machined with a groove. The model of the servo motor 13 is not limited, as long as it meets the usage requirements. The servo motor 13 can drive the turntable 11 to rotate. The groove can limit the pipe material when bending the pipe.

[0031] A support plate 10 is fixedly connected to the lower side of one side of the outer wall of the turntable 11. An electric push rod 8 is fixedly connected to the top of the support plate 10. A clamping block 9 is fixedly connected to the output end of the electric push rod 8. The model of the electric push rod 8 is not limited, as long as it meets the usage requirements. The electric push rod 8 can change the position of the clamping block 9, and thus limit the pipe by cooperating with the turntable 11.

[0032] Specifically, it should be noted that when using the electric push rod 8, a certain length of connecting wire needs to be reserved in order to avoid the phenomenon of wire pulling when the electric push rod 8 rotates. The specific reserved length can be determined according to the actual use situation. The specific preheating time of the pipe can be determined according to the material and wall thickness of the pipe. This case does not impose any restrictions on this, and the technical features of this case shall prevail.

[0033] Specific implementation steps:

[0034] During use, the operator inserts the pipe into the conveyor rail 6, then pushes the pipe to insert the part to be bent into the heating block 3. The control valve of the first conduit 5 is then opened, allowing the combustible gas inside the gas tank 14 to enter the cavity 4. Simultaneously, the small fan 15 is turned on, allowing outside air to fill the cavity 4. The igniter 17 is also turned on to ignite the combustible gas, heating the pipe. After heating, the operator continues to push the pipe between the turntable 11 and the clamping block 9. The electric push rod 8 is then activated, moving the clamping block 9. The clamping block 9 and the turntable 11 work together to clamp and fix the pipe. Finally, the servo motor 13 is activated, causing the turntable 11 and the clamping block 9 to rotate, thus bending the pipe.

[0035] In summary, this pipe bending machine for construction projects, through the arrangement of a horizontal plate, a housing, an air tank, a heating block, a cavity, a first guide pipe, a second guide pipe, a lighter, and a small fan, can preheat the pipe before bending it. This effectively avoids the drawbacks of cold bending, such as cracking or the need for greater bending torque to complete the bend. It also reduces springback, wrinkles, or elliptic deformation, ensuring the quality of the bending process. The servo motor, turntable, support plate, electric push rod, and clamping block can clamp and fix the pipe during bending, ensuring the quality of the bending and preventing pipe deviation. This invention, through improvements to the pipe bending machine for construction projects, has the advantage of preheating the pipe before bending, ensuring the quality of the bending, and also ensuring the stability of the pipe during the bending operation. Thus, it effectively solves the problems and shortcomings of existing devices.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
