Abstract
The invention relates to an electromagnetic induction heater of an ultra-low frequency special shaped workpiece, which is characterized in that an input end of electromagnetic coil turns is regulated to be connected to a compensate electromagnetic induction coil; the other input end of the electromagnetic coil turns is regulated to be connected to an electromagnetic induction coil. The advantageslie in that the electromagnetic coil turns and turn-to-turn distance can be randomly regulated to generate frequency changes and magnetic field distribution changes. Various special shaped workpiecesare applicable; the practicability is wide; the scope is big; energy cost can be saved; cost is lowered. Compared with traditional heat equipment coal furnaces, gas furnaces and baking furnaces and the like, the product has capability of strictly controlling heating in respect of any position of any workpiece; ultra-low frequency control is adopted; permeability is high; heating process is fast; the temperature control is good. An example of the special shaped workpiece is a hub.
Description
Technical field
What the present invention relates to is a kind of electromagnetic induction heater for ultra low frequency special-shaped working piece, belongs 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 objective of the invention is at the above-mentioned defective of existing in prior technology, proposition be a kind of electromagnetic induction heater for ultra low frequency special-shaped working piece, 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 invention: 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.Described two inputs are connected in series, and described two inputs are connected with coil by switch, and in addition, every circle coil all contains a link that can be connected with switch.
Advantage of the present invention: 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.Described two inputs are connected in series, and described two inputs are connected with coil by switch, and in addition, every circle coil all contains a link that can be connected with switch.
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.
