Description

Technical Field

[0001] This utility model belongs to the field of annealing furnace technology, specifically a high-efficiency box-type annealing furnace. Background Technology

[0002] Heat treatment furnaces are classified into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are mainly used for annealing large carbon steel and alloy steel parts; tempering surface-quenched parts; stress-relieving annealing and aging of weldments, and other heat treatment processes. Heating methods include electric heating, oil heating, gas heating, coal heating, and hot air circulation. Annealing furnaces are energy-saving periodic operation furnaces with ultra-energy-saving structures, using fiber structures to save 60% of electricity. Currently, when annealing parts, most parts are manually moved into the furnace. After heat treatment, they still need to be manually moved from the furnace to the outside. Due to the depth and space limitations inside the furnace, loading and unloading parts often requires a lot of time and physical labor. Annealing furnaces have long waiting times, and their work efficiency needs to be improved. Utility Model Content

A bottom bearing assembly is slidably disposed at the bottom end of the annealing furnace upper shell to form a closure at the bottom end of the annealing furnace upper shell. A side cover assembly is disposed on one side of the bottom bearing assembly to form a closure at the inlet of the annealing furnace upper shell. Guide rails are symmetrically disposed below the bottom bearing assembly. Mounting plates are disposed at the four corners of the bottom end of the bottom bearing assembly. A guide wheel is disposed at the center of the bottom end of the mounting plate, which abuts against the inner walls of both ends of the guide rail. Optical shafts are symmetrically disposed on the outer walls of both ends of the guide rail along its length. A drive wheel is disposed on one side of the guide wheel, and a follower wheel is disposed on the other side. Limiting grooves matching the optical shafts are opened on the outer surfaces of both the drive wheel and the follower wheel. A motor for driving the drive wheel to rotate is disposed on the bottom bearing assembly, and a bearing wheel is disposed on one side of the mounting plate.

[0005] Furthermore, the bottom support assembly includes a support base and a base plate disposed on the upper surface of the support base. The mounting plate is disposed at the four corners of the base. Support feet are symmetrically disposed in pairs at the bottom end of the upper shell of the annealing furnace. The width of the support base is smaller than the distance between the adjacent support feet. The top of the base plate abuts against the bottom end of the upper shell of the annealing furnace.

[0006] Furthermore, a first heat insulation layer is provided on the inner peripheral wall of the upper shell of the annealing furnace, a heating component is provided on the first heat insulation layer, a control cabinet body electrically connected to the heating component is provided at one end of the upper shell of the annealing furnace, and a second heat insulation layer matching the first heat insulation layer is provided at the top of the bottom plate.

[0007] Furthermore, the side cover assembly includes a side plate disposed on the outer side of the upper surface of the base plate, and a third heat insulation layer disposed on the inner side of the side plate and matching the first heat insulation layer, wherein the side plate is perpendicular to the base plate.

[0009] The beneficial effects of this utility model are:

[0010] This utility model utilizes a base, an upper shell of an annealing furnace, a bottom support assembly, a guide rail, a side cover assembly, a mounting plate, guide wheels, an optical shaft, a drive wheel, a follower wheel, a limiting groove, a motor, and a support wheel in a coordinated configuration. The bottom support assembly and the side cover assembly are driven by the motor to rotate the drive wheel, causing the drive wheel, follower wheel, guide wheel, and support wheel to move horizontally along the guide rail. This allows the bottom support assembly and the side cover assembly to move closer to or further away from the upper shell of the annealing furnace. Workers can move parts onto the bottom support assembly or remove heat-treated parts from the bottom support assembly from outside the furnace, without being limited by the internal space of the furnace. This saves time and effort, improves the efficiency of loading and unloading parts, and reduces the waiting time in the annealing furnace. Attached Figure Description
