Background technology
Along with China railways is to the development in high speed, heavy haul transport direction, also more and more higher to the requirement of circuit rail.The termination of current China railways point tongue is standard section rail, and starting material adopt AT(dwarf forms special section) rail, standard rail is adopted for circuit rail, to be connected with the standard rail on track, point tongue heel end must be shaped to standard rail, so must to point tongue heel end forging forming, heel end heating nature just becomes matter of utmost importance.
The requirement of rail heel end heating technique is very strict: (1) forbids burning; (2) crackle etc. must not be had to add thermal defect; (3) decarburized layer deepness≤0.5; (4) oxide skin can not have influence on geometrical dimension and the Geometrical Tolerance Principle at mechanical workout position; (5) homogeneous heating;
Traditional rail heel end heating adopts the industrial furnace such as coke process furnace or gas furnace to heat rail, have that rate of heating is slow, homogeneous heating degree is poor, heating and temperature control is accurate not, energy consumption is high, have the shortcomings such as pollution, Manual operation link is many, labour intensity is large to environment, modern need of production can not be adapted to, necessaryly to be improved.
Utility model content
Technical problem to be solved in the utility model is to provide the shaping induction heating device of a kind of track heel end, this shaping induction heating device has compared with traditional rail heel end heating means that rate of heating is fast, production efficiency is high, is oxidized and the plurality of advantages such as decarburization is few, pollution-free, less energy-consumption, homogeneous heating, core table has a narrow range of temperature, temperature control precision is high, labor condition is good, be convenient to mechanize and automatic production, the needs of modern production can be met.
The technical scheme solved the problems of the technologies described above is:
The shaping induction heating device of a kind of track heel end, it comprises load coil, circulating cooling water pipe, wiring board, the material of load coil is copper pipe, load coil is wound up as long spire shape by copper pipe, the two ends of load coil are connected with induction heating power by wiring board, the copper pipe mouth of pipe two ends of load coil are connected with circulating cooling water pipe respectively, are placed in the spirrillum cavity of load coil by the rail heated.
The shaping induction heating device of above-mentioned track heel end, the periphery of described load coil is connected with insulation fixing plate, insulation fixing plate is arranged with multiple standing bolt, and each standing bolt encloses corresponding being connected and fixed with one of load coil.
The shaping induction heating device of above-mentioned track heel end, described in be wound up as the load coil of long spire shape intracavity section shape be trapezoidal, the upper and lower ends width of trapezoidal inner chamber matches with the width of the rail level up and down of rail respectively.
The shaping induction heating device of above-mentioned track heel end, the electric capacity that the two ends wiring board of described load coil is supporting with induction heating power is respectively connected, and induction heating power is electrically connected with supporting electric capacity.
The beneficial effects of the utility model are:
The utility model adopts the load coil of long spire shape, and load coil passes into intermediate frequency or high-frequency current, and the inner chamber that load coil put into by rail carries out induction heating, after making rail reach requirement temperature, carries out heel end forming processes.The utility model overcomes the shortcoming of traditional industry stove heating rail, rail is heated convenient, have that rate of heating is fast, production efficiency is high, oxidation and decarburization few, pollution-free, less energy-consumption, homogeneous heating, core table has a narrow range of temperature, temperature control precision is high, the advantage of easily ensuring the quality of products, reducing labor intensity, improve rail rate of heating and heating quality, be convenient to mechanize and automatic production, there is significant economic benefit.
