Abstract
The invention relates to the field of vacuum heat treatment industry. At present, austenitizing, heating and quenching of chromium steel bearing rings produced in bulk by bulk materials are generally carried out in a continuous furnace, and the quenching of the bearing rings is easy to deform. The quenching oil groove in the roller furnace is changed into the quenching oil groove capable of realizing the spring quenching in oil. And the workpiece is placed in a heating chamber for heat treatment, and the workpiece is conveyed to a quenching chamber by a conveying device for cooling after the heat treatment. The quenching chamber tank cover is fallen down, the workpiece is covered, the propeller is started, the quenching oil is in a reciprocating circulation up and down such as spring by strong stirring of the propeller, and the tank rod channel ring is made to reciprocate left and right at the same time, so that the effect of small workpiece distortion can be better achieved.
Description
Technical field:
The present invention is the vacuum heat treatment industry field.
Technical background:
The austenitizing heating quenching of the chromium steel race ring of balk cargo batch process at present all carries out in continuous furnace usually, and the quenching of lasso is yielding.
Technology contents:
Oil-quenching tank in the roller formula stove changed into can realize in the oil that the spring formula quenches.When the lasso after the heating is delivered on the quenching tank with roller-way, groove upper cap falls, workpiece is covered, make quenching oil up and down reciprocatingly circulate gesture such as gush by the strong agitation of propeller, move back and forth about lasso on the quenching tank roller-way is also done simultaneously, so can obtain even cooling, the distortion of workpiece is controlled to minimum degree.The SAE52100 steel of ￠ 80～100mm (being equivalent to the GGr15 steel) neck collar wall thickness 4mm, distorsion during quenching can be controlled in 0.05mm～0.06mm scope.
Specific implementation method:
Workpiece is put into heating chamber heat-treat, the intact back of thermal treatment is transported to quenching chamber by transport unit with workpiece and cools off.Quenching chamber groove lid is fallen, workpiece is covered, start propeller, make quenching oil up and down reciprocatingly circulate gesture such as gush, allow the lasso left and right sides to-and-fro movement of groove rod road simultaneously, can better reach the little effect of workpiece distortion like this by the strong agitation of propeller.
