[0022] The rotation mechanism includes two fixing brackets 3, the fixing brackets 3 are fixedly installed on the base 1, the fixing brackets 3 are fixedly installed with fixing collars 301, the positioning die 1 is provided with two annular grooves, the annular grooves are adapted to the fixing collars 301, the base 1 is fixedly installed with a fixing frame 1 4, the fixing frame 1 4 is rotatably installed with a rotating rod 401, two gears 402 are fixedly sleeved on the rotating rod 401, the gears 402 are engaged with the gear rings 202, and the base 1 is fixedly installed with a stepping motor 403, and the output end of the stepping motor 403 is fixedly connected with one end of the rotating rod 401.

[0023] Such as Figure 1 and Figure 3As shown, four connecting blocks 203 are fixedly installed on both the positioning die 1-2 and the positioning die 2-201. A fastening bolt 204 passes through the corresponding connecting block 203, and one end of the fastening bolt 204 extends into the corresponding connecting block 203 and is threadedly connected to the corresponding connecting block 203;

[0024] By providing the connecting block 203 and the fastening bolt 204, it is convenient to fix the positioning die 2-201 on the positioning die 1-2 after installation, and then the base pipe can be physically clamped and straightened by the positioning die 1-2 and the positioning die 2-201.

[0025] As Figure 1 and Figure 2 As shown, the parallel adjustment mechanism includes a fixed frame 2-6. The fixed frame 2-6 is fixedly installed on the base 1. A screw rod 601 is rotatably installed on the fixed frame 2-6. A servo motor 602 is fixedly installed on the base 1. The output end of the servo motor 602 is fixedly connected to one end of the screw rod 601. A nut sleeve 603 is threadedly sleeved on the screw rod 601. One side of the nut sleeve 603 is fixedly connected to the thermal spraying machine 5. A connecting rod 604 is fixedly installed on the nut sleeve 603. The top of the connecting rod 604 is fixedly installed with a translation block 605. The top of the translation block 605 is fixedly connected to the heating nozzle 502;

[0026] After the servo motor 602 is energized and operates to drive the screw rod 601 to rotate in a spiral manner, the screw rod 601 drives the nut sleeve 603 to move parallelly, and then the nut sleeve 603 drives the translation block 605 on the connecting rod 604 to move parallelly. Therefore, it is possible to adjust the synchronous movement of the thermal spraying machine 5 and the heating nozzle 502 to adjust the position, which is convenient for heat treatment of the bent position of the base pipe after adjusting the position.

[0027] As Figure 2 As shown, a guide rod 7 is fixedly installed between the two fixed brackets 3. The guide rod 7 passes through the translation block 605 and is slidably connected to the translation block 605.

[0028] By providing the guide rod 7, the translation block 605 can slide on the guide rod 7, which is convenient for the translation block 605 to drive the heating nozzle 502 to move smoothly.

[0029] As Figure 2 As shown, two sliders are fixedly installed at the bottom of the thermal spraying machine 5. Two sliding grooves are opened on the base 1. The sliders are adapted to the sliding grooves;

[0030] By providing sliders at the bottom of the thermal spraying machine 5, when adjusting the parallel movement of the thermal spraying machine 5, the friction between the bottom of the thermal spraying machine 5 and the base 1 is reduced.

[0031] As Figure 3As shown in the figure, a spraying machine 8 is fixedly installed on the base 1. A water delivery pipe 801 is fixedly connected to the spraying machine 8. One end of the water delivery pipe 801 is fixedly installed with a spraying pipe 802, and the output end of the spraying pipe 802 is located above the positioning die 2.

[0032] After the water source is transported to the water delivery pipe 801 through the water pump inside the spraying machine 8, it is then transported to the spraying pipe 802 by the water delivery pipe 801. The water source is sprayed out through the output end at the bottom of the spraying pipe 802 to cool the positioning die 2 and the positioning die 201, so that the base pipe inside the positioning die 2 and the positioning die 201 can be quickly cooled and shaped after being straightened.

[0033] The working principle of the hot spraying base pipe straightening device provided by the present utility model is as follows:

[0034] The first step: Place the base pipe to be straightened on the positioning die 2, then cover the positioning die 201 above the positioning die 2, and press and straighten the base pipe. Then, by tightening the connecting block 203, the connecting blocks 203 on the positioning die 2 and the positioning die 201 are fixedly connected together, so that the positioning die 201 is fixedly installed on the positioning die 2.

[0035] The second step: The servo motor 602 is powered on to drive the screw 601 to rotate, and then the screw 601 drives the nut 603 to move parallelly, so that the nut 603 can drive the connecting rod 604 and the translation block 605 to move simultaneously. Then, the thermal spraying machine 5 and the heating nozzle 502 are driven to move synchronously to adjust the position, facilitating the heating nozzle 502 to approach the straightening part of the base pipe. Then, the thermal spraying machine 5 operates, and the fire source is sprayed out through the heating nozzle 502 to heat the outside of the positioning die 2 and the positioning die 201. At the same time, the stepping motor 403 is powered on to drive the rotating rod 401 to rotate, and then the rotating rod 401 drives the gear 402 to rotate, so that the toothed ring 202 engaged with the gear 402 is driven to rotate. Thus, the positioning die 2 is driven to rotate, so that the heating nozzle 502 can uniformly heat the positioning die 2 and the positioning die 201. Then, the base pipe clamped and straightened between the positioning die 2 and the positioning die 201 is heated to a semi-molten state. Therefore, the thermal spraying machine 5 is turned off, and then the spraying pipe 802 sprays water on the positioning die 2 and the positioning die 201 to cool down, so that the base pipe inside the positioning die 2 and the positioning die 201 can be quickly cooled and shaped after being straightened.
