Description
Technical field
The present invention relates to ball-screw production technical field, especially a kind of lead screw biliquid based on infrared temperature detection is quenched
Cooling method.
Background technique
Ball-screw is a kind of Rolling Components for converting rotary motion to linear motion, is numerically-controlled machine tool, precision
The important spare part of the various accurate mechanical equipments such as instrument.Ball-screw needs to bear at work bending, torsion, impact, together
When to bear frictional force in sliding and rotary part, belong to the workpiece for bearing the stress alternations such as torsion, bending, the requirement of this kind of workpiece
Surface can bear stress and friction power more higher than heart, that is, workpiece surface is required to have high rigidity, high intensity and enough resistance to
Mill property.
Impewdance matching can form the laser quenching hardened layer of high rigidity and high-wearing feature, and the heart of lead screw on lead screw surface rapidly
Portion is still able to maintain original performance, and lead screw center portion is made to have certain toughness, preferably adapts to the stress in process.
Impewdance matching is that quick heating is combined with quenching cooling, i.e., so that lead screw surface is reached quenching temperature by quickly heating
Degree, cools down immediately after, so that the heat on lead screw surface is not yet reached heart and cool down, so that lead screw surface hardening is martensite,
And lead screw heart is still unhardened original tissue.
The principle of impewdance matching are as follows: workpiece is placed in the inductor being coiled into hollow copper tubing, intermediate frequency is passed through or high frequency is handed over
After galvanic electricity, the induced current of same frequency is formed in workpiece surface, water-spraying control or immersion oil immediately after piece surface is heated rapidly
Quenching, makes workpiece surface layer harden.
The coolant liquid quenched after existing lead screw induction heating generallys use oil or water, water cool down at 800 to 600 or so
Curve is more gentle, and the temperature lowering curve when 600 to 300 spend sharply declines, according to water as single cold after induction heating
But liquid, when lead screw being be easy to cause to be cooled to 600 to 300 degree temperature range, since rapid cooling causes lead screw surface and heart to go out
Existing crackle.
Summary of the invention
Goal of the invention: in order to solve the above technical problems, the present invention proposes a kind of lead screw biliquid based on infrared temperature detection
Quenching method.
Technical solution: technical solution proposed by the present invention are as follows:
A kind of lead screw biliquid quenching method based on infrared temperature detection, comprising steps of
(1) the lead screw workpiece after heating magnetic induction is first fed into first order cooling body, is sprayed using first order cooling medium
Component sprays cooling water to lead screw workpiece；During spraying cooling water, lead screw workpiece is acquired in real time by infrared radiation thermometer
The temperature on surface；
(2) when the temperature of the collected lead screw workpiece surface of infrared radiation thermometer reaches 600 °, lead screw workpiece is cold from the first order
But it is taken out in mechanism, is sent into second level cooling body, spray cooling oil to lead screw workpiece with second level cooling medium sprinkler part,
Until lead screw workpiece is cooled to room temperature；
(3) ice-cold processing 60min is carried out to lead screw workpiece after cooling；
(4) tempering is carried out again after warming to room temperature lead screw workpiece guarantor.
Further, the temperature of the ice-cold processing is -60 ° to 0 °.
Further, the infrared radiation thermometer includes: optical system, photodetector, signal amplifier and signal processing
Module and display output module；Wherein, optical system converges the Target Infrared Radiation energy in its field range, and passes through photoelectricity
Detector is converted to electric signal, and electric signal is passed through aobvious by being changed into temperature value after signal amplifier and signal processing module
Show output module display output.
Further, when the cooling medium sprinkler part sprays cooling water or cooling oil to lead screw workpiece, emission direction
Angle with lead screw line length direction is 30 degree.
The utility model has the advantages that compared with prior art, present invention has the advantage that
The present invention can obtain the temperature on lead screw surface during impewdance matching in real time, switch coolant liquid in time, make full use of water and
The cooling characteristics of oil reduce the probability that lead screw surface is cracked in cooling procedure.
Specific embodiment
