After the pipe fitting is fixed, close the box door 26, start the motor 12 through the external controller, and the output end of the motor 12 drives the worm 11 to rotate, so that the worm 11 drives the worm wheel 10 and the rotating block 2 to rotate through the meshing relationship, and the rotating block 2 then drives the pipe fitting to rotate through the cross column 3 and the mounting block 4. At the same time, the worm 11 can drive the first bevel gears on both sides of the outside. 13 rotates, and the first bevel gear 13 drives the second bevel gear 15 and the reciprocating screw 14 to rotate through the meshing relationship, so that the reciprocating screw 14 drives the corresponding spray gun 6 to perform reciprocating and undulating motion under the limit of the limit frame 5 through the threaded connection relationship. At the same time, the spray gun 6 sprays hot air through the hose 17 and the hot air box 16 to heat the pipe fitting, and cooperates with the rotation of the pipe fitting itself to effectively improve the heating uniformity and heating efficiency of the pipe fitting. When the heating of the pipe fitting is completed, the cylinder 9 is started by the external controller, and the output end of the cylinder 9 drives the cross column 3 to descend, and the cross column 3 Then, the pipe is driven down by the mounting block 4, so that the bottom of the pipe pushes the sealing plate 19 to open, until the pipe is driven to the inside of the quenching box 7, and can be quenched by the cooling medium inside the quenching box 7.
