Description
Technical Field
The utility model belongs to the field of heat treatment processing equipment, relates to a heat treatment quenching furnace structure, and particularly relates to an air-cooled continuous heat treatment quenching furnace, which can realize rapid quenching and quenching of a piece to be quenched and has a continuous production function, and solves the problems that although a closed vacuum quenching furnace in the prior art can realize the rapid quenching effect of the piece to be quenched, continuous production cannot be realized, and although the continuous quenching furnace can realize the continuous production of a quenching process, a heated workpiece is slowly conveyed to a rear-section cooling section through a mesh belt, so that the rapid quenching effect is poor.
Background
Today's heat treatment furnace facilities can be roughly classified into 2 types as follows: one is a closed vacuum quenching furnace, and the other is a continuous quenching furnace with front heating section and back water cooling or oil cooling;
for a closed vacuum quenching furnace, such as chinese patent CN201921139480.4, the closed vacuum quenching furnace discloses a heat treatment vacuum quenching furnace, which comprises a quenching furnace main body, wherein a control cabinet is arranged on one side of the outer end of the quenching furnace main body, a base is connected to one side of the bottom end of the quenching furnace main body, a connecting pipe is fixedly communicated with one side of the outer surface of the quenching furnace main body, a vacuum pump is fixedly installed on one side of the outer end of the connecting pipe, a top cover is connected to one side of the top end of the quenching furnace main body through a pin, a pressure release valve is fixedly installed on one side of the top end of the top cover, and a temperature insulation plate is fixedly installed on one side inside the quenching furnace main body; through the arrangement of the placing frame, when a user needs to quench a workpiece, the user can place the workpiece on the placing frame, the user can control the servo motor to rotate through the control cabinet, the lead screw can be driven to rotate through the matching of the first gear and the second gear, and when the lead screw rotates, the connecting rod can be driven to lift up and down, so that the placing frame can be driven to lift up and down; through the limiting rod and the limiting groove, the placing frame can be placed stably in the quenching process conveniently, when the lead screw drives the placing frame to descend, the limiting groove arranged on the placing frame can be clamped into the limiting rod arranged on the heat insulation plate, so that the placing frame can be placed more stably through the matching of the limiting rod and the limiting groove, the stability of the device in quenching is improved, the device is convenient for a user to use, and the device is better than a traditional mode; therefore, although the heat treatment vacuum quenching furnace has a good heat treatment quenching effect, the working principle is a one-material-frame processing mode in consideration of the production process, the processing weight of each time every day is limited by a machine table, and the processing efficiency is low due to the processes of loading and unloading;
