Background technology
Titanium is a kind of metal of function admirable.The made titanium pipe of titanium or titanium alloy has characteristics such as density is little, intensity is high, corrosion resistance and good, fine heat-resisting performance, no magnetic, and industry has especially obtained to use widely in the nuclear industry in modern times.But compare with other material, the titanium shaping property is bad, and in the process of clod wash processing titanium pipe, because work hardening, cross section each several part mechanical performance is inhomogeneous, therefore occurs manufacturing deficiencies such as crackle easily.
The patent No. is the method and apparatus that discloses a kind of plug-type manufacturing large-sized heavy-wall tube in the patent of invention of ZL 200810031209.9; Can carry out cold machine-shaping to thick wall type titanium tube; But there are some problems in this method: its processing method is cold working; Owing to work hardening causes cracking problems of crack in the titanium pipe forming process, the titanium pipe mechanical performance of finally processing is uneven easily.
Summary of the invention
To the deficiency of above-mentioned roll forming method, the utility model aims to provide a kind of titanium pipe hot-rolling and bends making method and device thereof, and in order to solve titanium pipe roll forming problem, production line is low in energy consumption simultaneously, and reliability is high.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is following:
A kind of titanium pipe manufacturing process is characterized in that, earlier by uncoiler with titanium section bar to be processed uncoiling, and send into plate straightening roll and carry out leveling.Smooth subsequently titanium section bar is sent in the capable ripple induction heater by the strip guider and is heated.The titanium section bar carries out roll forming after space ripple induction heater is heated to predetermined temperature, promptly being admitted in the roll forming roller group.After the roll forming, the titanium section bar is cooled off by the section bar cooling device earlier, sends into processing such as shearing device cuts off by the section bar guider afterwards.The titanium pipe that final production goes out carries out the stacking vanning by discharge pedestal.
Capable ripple induction heater in the said equipment is different with common helical type load coil, and row ripple induction heater can utilize three phase mains to reach higher power in order to the thicker plate of processing.If the number of plies of common helical type induction coil coil winding is too much, then its outer coil will inevitably heat inner coil, and because outer be heated that the air gap increases between the section bar, can cause outer power factor reduction.Yet the row wave heater is positioned over each coil windings in a plurality of lines of rabbet joint of iron core successively.After feeding three-phase electricity, the alternating current in the winding can produce the at the uniform velocity magnetomotive force of rotation of a Sine distribution in the space, and wherein the section bar of process will be heated owing to the loss of energy of electromagnetic field.
With respect to common helical molded lines circle heating, row ripple induction heater can use three-phase electricity, and the multiphase load of balance is provided to power supply; The iron core of multi-layer stacks formula can be the magnetic flux interstitial gaps, thereby reduces the air gap greatly, has improved efficient; The induction coil winding needn't be near processed section bar, avoids coil to receive the section bar heat and generates heat.
Row ripple induction heater back is provided with a temperature-detecting device, is used for detecting in real time the temperature that is heated the titanium section bar, thereby and feed back to the watt level that computer system is revised coil windings, stablize the heating-up temperature of section bar.
The utility model and existing roll forming compared with techniques have following outstanding advantage and effect:
1. the titanium pipe formability of handling through row ripple eddy-current heating is good, and the work hardening phenomenon reduces, and internal stress is less, and toughness and ductility are good.
2. each phase load that the used capable ripple induction heater of equipment can the balance three phase mains, heating power is higher than common electrical magnetic coil, can heat roll bending to thicker titanium pipe.
