Abstract
Description
Technical Field
[0001] The invention relates to an induction heating coil for an induction heating device. Background Art
[0002] In the field of mechanical equipment, the assembly and disassembly of interference fit sleeves or couplings are all done by flame heating. A blowtorch is used to heat the sleeves around them, so that they can be expanded and then loaded or pulled out. This is generally only applicable to small-sized sleeves or couplings. When assembling and disassembling large-sized interference fit sleeves or couplings, uneven heating temperature or excessively high local temperature may cause the sleeves to deform and be damaged. Induction heating has the characteristics of fast and uniform heating. The induction coil is generally made of copper tubes. According to the different heating objects, the coils are made into different solenoid shapes, and the workpieces are placed in the induction coils for heating. However, since the assembly and disassembly of interference fit sleeves or couplings are generally carried out on site, induction coils made of copper tubes are not applicable, especially for interference fit sleeves or couplings of large machinery. Summary of the invention
[0003] The object of the present invention is to provide an induction heating water-cooling flexible coil.
[0004] The technical solution of the present invention is: an induction heating water-cooled flexible coil, including a positive electrode busbar, a negative electrode busbar, a positive copper sleeve connected to the positive electrode busbar, a negative copper sleeve connected to the negative electrode busbar, a water inlet joint installed on the positive copper sleeve, and a water outlet joint installed on the negative copper sleeve. Both ends of the cable are respectively inserted into the positive copper sleeve and the negative copper sleeve and connected to the positive electrode busbar and the negative electrode busbar. Both ends of the insulating rubber sleeve are respectively connected to the positive copper sleeve and the negative copper sleeve, and the insulating rubber sleeve is wrapped with an insulating pipe sleeve.
[0005] The cable is a braided cable formed by 100 to 5000 thousand 0.44mm high-strength, high-temperature and high-pressure resistant enameled wires.
[0006] The insulating rubber sleeve is a high-strength and high-temperature resistant PVC insulating rubber sleeve.
[0007] The insulating sleeve is a high-silica fiber insulating sleeve resistant to 1700°C.
[0008] The present invention has the following technical effects: the coil is made of cable and is flexible. The induction coil can be wound around an interference fit sleeve or coupling at the work station to form a spiral induction coil. The sleeve or coupling is heated by induction heating to expand it so that it can be installed or pulled out. The invention is particularly suitable for assembling and disassembling large interference fit sleeves or couplings. The heating is uniform without causing deformation and damage to the heating components. The coil is cooled by water to avoid burning of the coil during the heating process.
