Isothermal spheroidizing annealing furnace for automobile bearing ring machining

Abstract

The invention discloses an isothermal spheroidizing annealing furnace for automobile bearing ring machining. The isothermal spheroidizing annealing furnace for automobile bearing ring machining comprises an annealing furnace body, wherein a fixing plate is fixedly connected between the two sides of the inner wall of the annealing furnace body, and slide blocks are slidably connected to the two sides of the bottom of the fixing plate; a spray head is fixedly connected to the bottom of each slide block; a first motor is fixedly connected to the top of the annealing furnace body through a supportframe; a thread rod is fixedly connected to the output shaft of the first motor through a shaft coupling; the bottom end of the thread rod penetrates through the annealing furnace body and extends into the annealing furnace body; and one end extending into the annealing furnace body, of the thread rod, is rotationally connected with the top of the fixing plate through a bearing. The invention relates to the technical field of automobile bearing ring machining equipment. The isothermal spheroidizing annealing furnace for automobile bearing ring machining is capable of greatly annealing a bearing ring, and short in annealing time, thereby greatly increasing the annealing efficiency and improving the quality of the bearing ring.

Description

technical field [0001] The invention relates to the technical field of processing equipment for automobile bearing rings, in particular to an isothermal spheroidizing annealing furnace for processing automobile bearing rings. Background technique [0002] The isothermal spheroidizing annealing process is a spheroidizing annealing process in which eutectoid steel or hypereutectoid steel is heated, held for an appropriate time, and then cooled to a temperature slightly lower than Ar1, kept isothermally for a certain period of time, and then furnace-cooled or air-cooled. The network carbides in the original structure are serious, and when the austenitization temperature is high, the number of undissolved carbides is small, the austenite grains are large, and the distribution of carbon content in them is relatively uniform, which is not conducive to spheroidization During the process, when the isothermal transformation temperature is low, it is difficult for carbon to diffuse in...
