Description
Technical field
The utility model belongs to the general heating installation technical field of used for metal thermal treatment, relates to the induction heating device that a kind of heat treatment of workpieces is used, especially for the induction heating device of cutter blade thermal treatment (containing thermo-chemical treatment).
Background technology
In order to improve the mechanical property of various metal works, require workpiece is strengthened thermal treatment.In this type of thermal treatment, adopt the more of induction heating, because it has advantages such as heating is fast, efficient is high, decarburization is few, quality is good, pollution-free.As everyone knows, cutter is that people are widely used in the parting tool of shearing metal (or nonmetal).And the present cutter of producing adopts three kinds to strengthen heat treating method usually: the one, and with high carbon tool steel (containing alloy tool steel) or rapid steel manufacturing, whole heating quenching and tempering; The 2nd, use the low-carbon alloy steel manufacturing, surperficial carbonitriding; The 3rd, use the medium carbon alloy steel manufacturing, the salt bath boronising is handled.In the last thirty years, no matter cutter is strengthened heat treated whole heating or surface heating, in order to improve the cutter quality, reduce cost and to prevent the pollution of the environment etc., above-mentioned induction heating mode with efficient, energy-conservation, high-quality, cleaning, advantage such as flexible, just begin to be applied in the reinforcement thermal treatment of cutter, and obtained favorable economic benefit.For cutter, the local strengthening of cutter blade is even more important.But it is less that induction heating is used for the partial heat treatment of cutter blade.This is because limited by the shape of cutter blade, and is difficult for designing comparatively ideal induction heating device.The features of shape of cutter blade is: 1, shape is thinner, and the area in its transverse section is little; 2, special-shaped transverse section, and its blade end is very sharp.Like this, just give design corresponding induction heating device, brought sizable difficulty.
Be used for the partial heat treatment of cutter blade along with induction heating, but there is following shortcoming in existing cutter blade induction heating device: existing cutter blade induction heating device, what the overwhelming majority adopted is " longitudinal magnetic field " type of heating, and this type of heating is unfavorable for that thin cutter blade carries out induction heating.We know, no matter difform steel are plate, pipe, section bar, every employing induction heating, all can be divided into " longitudinal magnetic field " heating or " transverse magnetic field " heating dual mode basically.Wherein, pipe, section bar adopt the former mode basically; And, adopt two kinds of type of heating all to have for sheet material, wherein, thin sheet material then adopts latter's mode more.And thin cutter blade adopts the former " longitudinal magnetic field " type of heating, then its heating will have substantial connection with the area in its transverse section, be subjected to less limit of area in its transverse section, directly have influence on the optimized choice of power unit power and frequency, and cause heating efficiency relatively poor; Have, quenching strain is bigger again.Through the thermal treatment cutter that existing cutter blade induction heating device heats, its quenching strain is all bigger usually.The quenching strain of cutter mainly shows as side roughness and knife-edge distortion.Wherein, the side roughness still can be controlled or be proofreaied and correct; And the knife-edge distortion is difficult to eliminate.Like this, the weak point of above-mentioned existing cutter blade induction heating device has just limited the application of induction heating in the thermal treatment of cutter blade.
Summary of the invention
The purpose of this utility model is, a kind of novel induction heating device cutter blade, that can form " transverse magnetic field " type of heating that is used for is provided, in the hope of help the cutter blade fast, efficient, high-quality, energy-conservation heating.This cutter blade induction heating device mainly is made up of coil, magnetizer, watercooling jacket etc.Wherein, coil is " semisellar " many groups, multi-loop copper tube by the ad hoc fashion coiling; It by many groups (being generally 2 groups) respectively by " half saddle type " multi-loop copper tube (being generally single turn or 2 circles) of ad hoc fashion symmetry coiling, parallel with one another again combining.When coil can heat the blade of cutter, also the certain section near its blade in the cutter is carried out partial preheating, so that effectively control the knife-edge flexural deformation of cutter.The copper pipe of coil adopts hollow square (or rectangle) pure copper tube of certain wall thickness to make, and needs the water flowing cooling.Magnetizer is to adopt the siliconized plate in groups of specified shape to be formed by stacking, or makes of other magneticsubstances; Its decoration form and position, and the specified shape of magnetizer all are for the magnetic line of force that makes its cutter blade place is more intensive, and penetrate this place's sectional layer in " transverse magnetic field " mode, and then reach the heating of strengthening this place.Certainly, in some cases, this induction heating device can not have magnetizer yet, does not promptly add magnetizer.In order to help the cooling of magnetizer, in its outer setting one group of watercooling jacket; Equally, no magnetizer, also just need not add watercooling jacket.The heating power supply of this induction heating device, its power frequency can be according to the zone of heating degree of depth, and select the power unit of intermediate frequency or high frequency for use.Therefore, this induction heating device has the efficient height, and heating is fast, and quality is good, be out of shape little, less energy consumption, low cost and other advantages.
This cutter blade induction heating device, it not only can heat continuously to the cutter blade, heating when also can adopt the cutter blade; It not only can carry out induction heating to the thermal treatment of cutter blade, also can carry out induction heating to the thermo-chemical treatment (as paste boron-doping, metallic cementation etc.) of cutter blade.
