[0027] like Figure 1-Figure 10 A heating, quenching and straightening integrated device comprises a device body 1, on which a straightening device 2, a high-frequency unit 6 and a quenching liquid tank 7 are arranged, the straightening device 2 comprises two groups of straightening rollers 9 arranged side by side, each straightening roller 9 group comprises more than two straightening rollers 9, the straightening rollers 9 are connected to a driving device 1, the high-frequency unit 6 has an annular induction heater 11, the quenching liquid tank 7 is provided with a quenching liquid spray ring 14 and a quenching pump 15, the inner side of the quenching liquid spray ring 14 is uniformly distributed with a plurality of spray holes 17, and the quenching pump 15 is connected to the inside of the quenching liquid tank 7 and the quenching liquid spray ring 14 through a pipeline.

[0028] When in use, the drill rod 10 is inserted between two groups of straightening rollers 9 arranged side by side. The bending direction of the drill rod 10 should be toward the straightening roller 9. The axle of the straightening roller 9 is connected to the device body 1 through a bearing seat, and the bearing seat is rotatably connected to the axle. The bearing seat is connected to the device body 1 through bolts, and the device body 1 is provided with a waist hole at the bolt position to adjust the position of the bearing seat, so as to adjust the distance between the side-by-side straightening rollers 9. The adjustment range is 10mm-40mm to accommodate drill rods 10 of different sizes. After the drill rod 10 is inserted between the two groups of straightening rollers 9, due to the restriction of at least four straightening rollers 9 on the drill rod 10, the drill rod 10 can be conveyed to the annular induction heater 11 while straightening the bent part. The driving device 1 can be a straightening motor 8 in combination with a belt drive component 1 or a chain drive component 1. The housing of the straightening motor 8 The straightening motor 8 is fixed to the device body 1, and the output shaft of the straightening motor 8 is connected to the axle of one of the straightening rollers 9 in one group of the straightening rollers 9 through a coupling 14, and then a belt drive component 1 or a chain drive component 1 is used to drive the other straightening rollers 9 in the same straightening roller group 9 to rotate synchronously, so as to drive the drill rod 10 to move toward the annular induction heater 11.
