Problems solved by technology

[0002] When using a heat treatment furnace to heat treat steel balls, it is necessary to tilt the heat treatment furnace to pour the steel balls out of the discharge pipe. However, the diameter of the discharge pipe of the existing heat treatment furnace is about 200mm, and the time for pouring the balls is about 20 minutes. When pouring balls, the furnace cover is continuously opened, and the steel balls in the heat treatment furnace fall into the cooling column one by one, and the outside air continues to enter the heat treatment furnace through the discharge pipe, resulting in a decrease in the temperature of the heat treatment furnace, resulting in the The temperature of the steel ball is lower than the preset value, which affects the quenching and tempering effect of the steel ball

Abstract

A steel ball heat treatment furnace comprises a furnace body, the furnace body is provided with a discharging pipe, an opening mechanism is installed on the furnace body, and one end of the opening mechanism is connected with a sealing device. The opening mechanism comprises a telescopic rod, a support fixedly connected to the furnace body, a rotating shaft connected to the support through a shaftand a rocker connected with the middle of the rotating shaft through a shaft. One end of the telescopic rod is hinged to the furnace body, and the other end is hinged to the upper end of the rocker.The sealing device comprises a furnace cover and a shell, a first bearing is arranged in the shell, and a hollow shaft is installed in the first bearing. One end of the hollow shaft is fixedly connected with the furnace cover, a through hole communicated with the hollow shaft is formed in the furnace cover, the shell is fixedly connected to the lower end of the rocker, and the discharging pipe iscovered with the furnace cover. According to the present invention, the furnace cover can be opened and closed intermittently, the excessive external air entering the discharging pipe is reduced, andthe steel ball hardening and tempering effect is improved.
