Description
Technical field
The present invention relates to induction quenching technology field, more particularly to a kind of ball-and-socket class workpiece induction hardening method and positioning dress
Put.
Background technology
For both requiring that top layer has high wearability, fatigue resistance, larger shock loading can be born, requires whole again
Body has the workpiece of good plasticity and toughness, typically using Surface heat-treatent.Surface heat-treatent is generally divided into thermo-chemical treatment
With the major class of surface hardening two.Wherein surface hardening is, by more than heated partses top layer to critical-temperature rear rapid cooling, to make work
Part top layer obtains required hardened structure and center portion still keeps the heat treatment method organized originally.Different, the table according to mode of heating
Face quenching can be divided into induced surface hardening, surface hardening by flame heating, Electricity Contact Heating surface hardening, laser heating surface
Quenching etc., industrially widely used is induced surface hardening.
Induced surface hardening is exactly to produce vortex in workpiece using electromagnetic induction principle and heated workpiece,
The then process for quenching of chilling.Quenching workpiece is needed to have certain inductor to correspond, the effective heating part of inductor
Shape is typically similar to heated face shape.Quenching workpiece is needed also to have positioner, the positioner needs to ensure that workpiece is put
Put reliable, the accurate positioning between workpiece and inductor.Need the shape of impewdance matching workpiece varied at present, except ensureing sense
Answer the shape of device accurately outer, the positioning of workpiece is also key point.
As shown in figure 1, ball-and-socket class workpiece is commonly referred to as the support class workpiece contacted with bulb class workpiece, with part ball
Nest face, in ball-and-socket face, screwed hole is typically distributed with surrounding.It is for the inductor to ball-and-socket class workpiece surface progress sensing heating
Ball-and-socket inductor, shape similar to ball-and-socket face but smaller sphere diameter is typically turned to by copper tube, is probeed into during heating in ball-and-socket, with
There is certain gap on ball-and-socket surface.When carrying out induction hardening in the ball-and-socket face to ball-and-socket class workpiece, it can use and ball-and-socket face
The ball-and-socket inductor heating of likeness in form, if positioning between inductor and workpiece and apart from adjust it is improper heating can be caused uneven,
Hardness deficiency or hardening flaw occurs in subregion after quenching, causes workpiece to be scrapped, this patent provides technical scheme
Based on using a kind of impewdance matching positioner for being common to ball-and-socket class workpiece, workpiece is set to keep accurate during sensing heating
Positioning, realize while heating while rotate, make ball-and-socket face homogeneous heating.
Ball-and-socket class workpiece species for bulldozer working device is various, except ball-and-socket face part, remainder structure shape
