Abstract
The utility model relates to quenching equipment for a shaft and a shaft sleeve of a crawler belt. The quenching equipment comprises a quenching furnace, a feeding mechanism, a bench feeding platform and a bench discharging platform connected to two ends of the quenching furnace, and an electric control cabinet connected with the equipment, wherein the feeding mechanism comprises a material storeroom and a pneumatic feeding platform connected with the material storeroom. The quenching equipment is characterized in that a pre-quenching device for the shaft and the shaft sleeve is arranged between the bench feeding platform and the pneumatic feeding platform. The quenching equipment has the beneficial effects of being simple in structure, convenient to use, and applicable to quenching the shafts and shaft sleeves of various models of crawler belts, on the one hand, the service life of the shaft and the shaft sleeve of the crawler belt is prolonged, and thus on the other hand, the problem of inconvenience in inner ring tempering of the shaft sleeve of the crawler belt is solved.
Description
Technical field
The utility model relates to a kind of axle, axle sleeve processing units of track section, especially relates to a kind of axle, axle sleeve quenching processing units of track section.
Background technology
At present, when steel alloy tempering, hardness one tempering temperature relation curve is in the phenomenon of second maximum value of 500～600 ℃ of appearance.The cause of tempering secondary hardening, the one, the precipitation of alloy martensite alloy carbide in the time of high tempering, causes martenaging martempering secondary hardening; The 2nd, the secondary quenching of retained austenite, changes martensite into when cooling after tempering.
In high quality steel, stability of retained austenite is stronger, and 500 ℃ of following tempering do not change; When 500～600 ℃ of tempering insulations, also do not undergo phase transition, change martensite into and there is secondary quenching when cooling.But secondary quenching martensite also must tempering (malleableize) can drop into military service.Therefore, the secondary hardening ability of steel in fact only depends on the process of alloy martensite secondary hardening: the essence of precipitate and quantity.
At present, the rigidity of the track section of existing heavy-duty vehicle requires very high, more and more higher for the requirement of processing, and common track section is just through a temper, is following high rigidity requirement thereby do not reach raising track section.And be generally all difficult to process in the inner ring tempering of the axle sleeve of track section.
Utility model content
