Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a hot bending device for steel pipes of power transmission towers, which includes a base 1, a heat insulation box 4 erected on one side of the top of the base 1, and an intermediate frequency heating coil 12 assembled inside the heat insulation box 4. A blanking window 11 is opened at the top of the base 1, and a material guiding plate 10 is connected to the bottom of the base 1; fixing frames 8 are installed on the top of the base 1 on both sides of the blanking window 11, and a clamping mechanism 6 is movably installed between the fixing frames 8 through a screw rod 7. Moving mechanisms 2 are symmetrically installed at both ends of the top of the base 1. The moving mechanism 2 includes a positioning plate 201, a hydraulic cylinder 202, and a mounting plate 203. The two positioning plates 201 are symmetrically distributed and are fixedly installed on the top of the base 1. Both ends of the hydraulic cylinder 202 are respectively connected to the positioning plate 201 and the mounting plate 203. The first clamping die 3 and the second clamping die 5 which are adapted to each other are respectively assembled at one end of the mounting plate 203 close to the blanking window 11. Among them, the shapes of the first clamping die 3 and the second clamping die 5 can be preset according to the shape required for the steel pipe of the power transmission tower.

[0022] Based on the above structure settings, the hot bending device for power tower steel pipes consists of a base 1, a heat insulation box 4 erected on one side of the top of the base 1, and an intermediate frequency heating coil 12 assembled inside the heat insulation box 4. Among them, the base 1 provides support for the structure where the device is installed. After the intermediate frequency heating coil 12 is powered on, it can perform large-area heating treatment on the steel pipes that need to be heated. The heat insulation box 4 is used to wrap and protect the intermediate frequency heating coil 12 to reduce heat loss. Specifically, during the working process, the clamping mechanism 6 is used to clamp the power tower steel pipes that need to be hot bent. After clamping, under the guidance of the screw rod 7, the clamping mechanism 6 extends the part of the steel pipe that needs to be bent into the inside of the intermediate frequency heating coil 12. The intermediate frequency heating coil 12 is used to stably heat the power tower steel pipe in a surrounding manner. After heating, the clamping mechanism 6 withdraws the power tower steel pipe from the inside of the intermediate frequency heating coil 12 under the guidance of the screw rod 7. The withdrawn power tower steel pipe stays between the first clamping die 3 and the second clamping die 5. After the hydraulic cylinder 202 is started, the output end drives the mounting plate 203 to approach the blanking window 11. During the approaching process, the first clamping die 3 and the second clamping die 5 are used to clamp and deform the power tower steel pipe, so that the power tower steel pipe forms a specific shape. After the deformation is completed, the clamping mechanism 6 releases the clamping of the power tower steel pipe. The falling power tower steel pipe enters the inside of the blanking window 11 and is discharged from the front end of the device under the guidance of the guide plate 10. This hot bending device for power tower steel pipes can eliminate the traditional shaping steps required after bending deformation by using the first clamping die 3 and the second clamping die 5 to deform the heated power tower steel pipe, improving production efficiency. The shapes of the first clamping die 3 and the second clamping die 5 can be preset according to the shapes required by the power tower steel pipes. The processed power tower steel pipes are guided and discharged through the guide plate 10 and the blanking window 11, facilitating the collection by the user.

[0023] Furthermore, the clamping mechanism 6 includes a moving seat 601, an electric push rod 602, and a clamping plate 603. Screw sleeves adapted to the screw rod 7 are installed at both ends of the moving seat 601. Two electric push rods 602 are symmetrically distributed in the opposite direction on the top of the moving seat 601. The clamping plates 603 are symmetrically distributed at both ends of the bottom of the moving seat 601, and the top of each clamping plate 603 penetrates the moving seat 601 and is connected to the output end of the electric push rod 602. Among them, a groove for the movement of the clamping plate 603 is provided on the moving seat 601. After the electric push rod 602 is started, its output end can drive the clamping plate 603 to move at the bottom of the moving seat 601, thereby using the clamping plate 603 to clamp the pipe materials for use.

[0024] Further, the clamping mechanism 6 further includes a slider 604 and a chute 605. The bottom of the slider 604 is connected to the clamping plate 603, and a chute 605 adapted to the slider 604 is provided at the bottom of the moving seat 601. Among them, the vertical plane of the slider 604 and the chute 605 is a T-shaped structure, and the smoothness of the movement of the clamping plate 603 can be increased through the slider 604 and the chute 605.

[0025] Further, a number of bolts 14 are symmetrically distributed inside the mounting plate 203, and the ends of the bolts 14 penetrate through the mounting plate 203 and are respectively connected to the first clamping die 3 and the second clamping die 5. Among them, screw holes adapted to the bolts 14 are provided at the end faces of the first clamping die 3 and the second clamping die 5 close to the mounting plate 203. The first clamping die 3 and the second clamping die 5 can be assembled through the bolts 14, so that the user can replace the first clamping die 3 and the second clamping die 5 with different shapes according to needs.

[0026] Further, a number of support columns 13 are distributed on both sides of the bottom of the base 1. Among them, the top of the support column 13 is connected to the base 1, and the support column 13 is not installed at the front end of the material guiding plate 10. The base 1 is supported by the support column 13 during use, so that the user can operate and use the device.

[0027] Further, a motor 9 is installed on the other side of the fixing frame 8. The output end of the motor 9 is fixedly connected to the screw rod 7, and the screw rod 7 is movably connected to the fixing frame 8. Among them, after the motor 9 is started, it can provide power for the rotation of the screw rod 7, so that the user can adjust the position of the clamping mechanism 6 according to needs.
