The plastic pipe 3 and the steel pipe 4 are in interference fit at normal temperature, the length of the plastic pipe 3 is larger than that of the steel pipe 4, before the plastic pipe 3 is sleeved, the plastic pipe 3 needs to be cooled down to enable the diameter of the plastic pipe 3 to be smaller than that of the plastic pipe 3 at normal temperature, then one end of the cooled plastic pipe 3 is arranged on the first clamping device 22, the steel pipe 4 penetrates from one end of the electromagnetic coil 21 along the length direction of the workbench 1 and is arranged on the second clamping device 23, the second clamping device 23 clamps the steel pipe 4, the driving device 231 and the electromagnetic coil 21 are synchronously started, the driving device 231 drives the steel pipe 4 to move along the length direction of the workbench 1, the electromagnetic coil 21 heats the steel pipe 4, after the whole section of the steel pipe 4 is heated, the driving device 231 drives the steel pipe 4 to slide to be right below the second clamping device 23, and two ends of the steel pipe 4 are symmetrical relative to the second clamping device 23, the sliding table 26 drives the first clamping devices 22 which clamp the plastic pipe 3 to move along the length direction of the workbench 1, the cooled plastic pipe 3 and the heated steel pipe 4 are in clearance fit, the first clamping devices 22 which do not clamp the plastic pipe 3 are close to the plastic pipe 3, when the two first clamping devices 22 clamp the two ends of the plastic pipe 3, the heating devices 24 are started, the electromagnetic coil 21 is closed, the steel pipe 4 is cooled, the heating devices 24 heat the plastic pipe 3, so that the plastic pipe 3 and the steel pipe 4 are sleeved together, the two sliding tables 26 drive the two first clamping devices 22 to be close to each other, the sealing ring devices squeeze the two ends of the plastic pipe 3, the sealing ring 31 is formed at the two ends of the plastic pipe 3, so that when the plastic pipe 3 is sleeved in the steel pipe 4, the pipe wall of the plastic pipe 3 cannot rub with the pipe wall of the steel pipe 4, the damage condition of the plastic pipe 3 when being sleeved in the steel pipe 4 is avoided, and the integral strength of the sleeve after the sleeve is sleeved is improved.
Referring to fig. 8 and 9: the first clamping device 22 includes a moving frame 221, a moving case 222, an air pump 223, an extension rod 224, and an air bag 225; the movable frame 221 is fixedly arranged on the sliding table 26, and the movable frame 221 slides along the length direction of the workbench 1 along with the sliding table 26; the moving case 222 is fixedly provided on the moving frame 221; the extension rod 224 is fixedly arranged on the side wall of the movable housing 222 along the length direction of the workbench 1; the air bag 225 is sleeved on the periphery of the extension rod 224; an air pump 223 is provided on the moving case 222, and the air pump 223 communicates with the air bag 225.
Because there is the difference in the size of plastic pipe 3, in order to be able to hold all plastic pipes 3, it is required that first clamping device 22 can change relatively along with the size of plastic pipe 3, when installing plastic pipe 3, establish the one end of plastic pipe 3 on extension rod 224 along the axis cover of extension rod 224, then air pump 223 starts, air pump 223 pumps into gasbag 225, gasbag 225 takes place the inflation under the continuous intussuseption of gas, gasbag 225 after the inflation supports plastic pipe 3, because extension rod 224 sets up in the inside of plastic pipe 3, even extension rod 224 is longer also can not influence plastic pipe 3 cup joint on steel pipe 4, simultaneously guaranteed that extension rod 224 has sufficient atress area when supporting plastic pipe 3, the circumstances that damage appears when first clamping device 22 held in to plastic pipe 3 has been avoided.
Referring to fig. 5 and 9: the heating device 24 includes an igniter 241, a gas ejection head 242, and a fan 243; a first through groove is formed in the movable shell 222 along the length direction of the workbench 1, a second through groove is formed in the extension rod 224 in a penetrating manner along the axis of the extension rod, the first through groove and the second through groove are mutually communicated, and an igniter 241 is fixedly arranged in the first through groove; the gas spraying head 242 is fixedly arranged on one side of the igniter 241, and the gas spraying head 242 can spray gas into the first through groove; a fan 243 is provided on the moving case 222, and the fan 243 can blow air in the first through groove into the second through groove.
When the plastic pipe 3 needs to be heated, the igniter 241 ignites, the gas injection head 242 injects gas, flame is generated in the first through groove, then the fan 243 is started, the fan 243 blows air in the first through groove into the second through groove, meanwhile, the ignited flame is blown in, the flame enters into the plastic pipe 3 through the second through groove, the flame in the plastic pipe 3 rapidly heats the plastic pipe 3, meanwhile, the steel pipe 4 outside the plastic pipe 3 is also in a high-temperature state, the plastic pipe 3 rapidly heats under the double action, and meanwhile, the plastic pipe 3 absorbs heat at the steel pipe 4, so that the steel pipe 4 can be cooled down rapidly, and the plastic pipe 3 can be attached to the steel pipe 4.
Referring to fig. 1: the heating device 24 also includes a baffle 244; the baffle 244 is fixedly provided at an end of the table 1.
Since the plastic tube 3 needs to be heated when the plastic tube 3 is sleeved, and the mode adopted when the plastic tube 3 is heated is that fuel gas is sprayed into the plastic tube 3, the air flow generated by the fan 243 heats the whole plastic tube 3, although the cooled plastic tube 3 can be quickly restored and attached to the steel tube 4, under the guidance of the plastic tube 3, the other end of the plastic tube 3 has a flame which is sprayed out, if a baffle 244 is not arranged on one side where the flame is generated, the situation that the surrounding staff is burnt is caused, and after the baffle 244 is arranged, the sprayed flame can be blocked by the baffle 244, so that the situation that the surrounding staff is burnt is prevented.
