Abstract
The utility model relates to an ultra-low frequency electromagnetic induction heater for irregular workpieces, which is characterized in that an input end for regulating the turn number of an electromagnetic coil is connected with a compensating electromagnetic induction coil, and the other input end thereof is connected with the electromagnetic induction coil. The utility model has the advantages that the number of turns and the distances between the turns of the electromagnetic coil can be regulated optionally in order to produce the variation of the frequency and the magnetic field distribution; and the heater is suitable for various irregular workpieces, has wide practicability and a wide application range, saves the energy consumption and reduces the cost. Compared with the traditional heat treatment facilities such as a coal furnace, a gas furnace, a roasting furnace and the like, the utility model has the function of heating any parts of any workpieces like wheel hubs and other deformed workpieces under strict ultra-low frequency control and has the advantages of strong permeability, high heating speed and good temperature control.
Description
Technical field
The utility model relates to a kind of electromagnetic induction heater for ultra low frequency special-shaped working piece, belong to the electromagnetic induction heater field.
Background technology
Prior art is to regulate to the special shape of special-shaped workpiece and the heating-up temperature of privileged sites, does not reach required heating-up temperature.The male and fomale(M﹠F) situation complexity of special-shaped workpiece, the temperature difference that different positions is required can't accomplish uniform temp is evenly distributed on the workpiece, can't satisfy the requirement of uniform heat treatment heating-up temperature.Thereby influence the properties of product of special-shaped heat treatment of workpieces.
Summary of the invention
The purpose of this utility model is to propose a kind of electromagnetic induction heater for ultra low frequency special-shaped working piece at the above-mentioned defective of existing in prior technology, and it can effectively overcome above-mentioned defective.Satisfy the requirement of the uniform heat treatment heating-up temperature of special-shaped workpiece.
Technical solution of the present utility model: its structure is that input and the compensation electromagnetic induction coil of regulating the solenoid number of turn join, and another input and the electromagnetic induction coil of regulating the solenoid number of turn join.
Advantage of the present utility model: can regulate the solenoid number of turn arbitrarily, the turn-to-turn distance produces the frequency change Distribution of Magnetic Field and changes.Adapt to various special-shaped workpiece, practicality is wide, and scope is big, and energy efficient reduces cost.As traditional Equipment for Heating Processing coal stove, vapour stove, baking furnace etc.This product function can be carried out strictness control heating at any part of any workpiece, adopts ultralow frequency control, and permeability is strong, and heating is fast, and temperature control is good.Special-shaped workpiece such as wheel hub.
Description of drawings
Accompanying drawing 1 is the structural representation of electromagnetic induction heater for ultra low frequency special-shaped working piece.
Accompanying drawing 2 is example structure schematic diagrames.Unit: cm.
Embodiment
Contrast accompanying drawing 1, its structure are that input and the compensation electromagnetic induction coil of regulating the solenoid number of turn join, and another input and the electromagnetic induction coil of regulating the solenoid number of turn join.
Contrast accompanying drawing 2, the A among the figure, B, C, D, E, F, G are the workpiece to be machined zones.Wherein the temperature of work piece zone A, B, D, E, F is greater than 800 ℃, and work piece zone C temperature is less than 780 ℃, and work piece zone G temperature is less than 760 ℃.
The concavo-convex size of workpiece, size, profile, the thickness overall region is according to the other shaped of workpiece to be heated, special-shaped solenoid and compensation electromagnetic coil accurately are set, solenoid and compensation electromagnetic coil design simultaneously can regulate the number of turn and turn-to-turn distance, changes many groups of adjustings of frequency functionality, so that according to the special shape of special-shaped workpiece and the heating-up temperature needs of privileged sites, in time regulate, so that reach required heating-up temperature.Because of heated parts is decided, calculate establishment according to other shaped.The solenoid material side of selection copper pipe, power division how much, the side's of determining copper pipe specification.Regulate the electromagnetic induction coil number of turn, increase or reduce, input voltage, electric current changes, and changes size decision magnetic field intensity, eddy current.This electromagnetic induction heating is in the special-shaped heat treatment of workpieces heating process of reality, rely on the magnetic field of electromagnetic induction heating to be used for male and fomale(M﹠F) situation diverse location to special-shaped workpiece exactly, required different temperatures and diverse location, required uniform temp and precision, on the equally distributed workpiece, can guarantee ideal, heat treatment heating-up temperature requirement uniformly.
Described electromagnetic induction coil requires: be provided with at special-shaped workpiece shape; Guarantee that electromagnetic induction coil is when design and the appropriate distance of special-shaped workpiece; According to special-shaped workpiece weight, parameter designing such as heating time, selection, the side's of determining copper pipe specification.
