Description

Technical Field

[0001] The utility model relates to the technical field of tempering furnaces, in particular to a tempering furnace door. Background Art

[0002] Tempering furnace is a kind of equipment specially used for tempering metal materials. Tempering is an important part of metal heat treatment process. Its purpose is to eliminate the internal stress and brittleness generated during quenching, improve the toughness and plasticity of metal, and make the material reach the expected mechanical properties. It is widely used in automobile, machinery, metallurgy, aviation and other fields. It is an indispensable and important equipment in the process of metal material processing and manufacturing.

[0003] The door of the tempering furnace is a key component in the tempering process. It not only controls the stability of the temperature in the furnace, but is also directly related to the circulation and protection of the atmosphere in the furnace. Some tempering furnaces use suspended lifting tempering furnace doors, which can realize the rapid and smooth opening and closing of the furnace door. However, during the lifting process of this type of furnace door, due to factors such as mechanical structure and thermal expansion, it is difficult to achieve complete gaplessness with the furnace mouth. Appropriate gaps can accommodate these minor changes and prevent the furnace door from being subjected to excessive resistance when lifting or closing, thereby ensuring the smooth operation of the furnace door. However, the gap between the furnace door and the furnace mouth may cause leakage of heat and atmosphere, which will affect the stability of the temperature in the furnace and the uniformity of the atmosphere, and thus affect the effect of the tempering treatment.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, a tempering furnace door provided by the utility model comprises a tempering furnace body 1 and a furnace door 6, a furnace door truss 2 is fixedly installed at the front end of the tempering furnace body 1, two winding mechanisms 3 are fixedly installed on the upper end of the furnace door truss 2, and the two winding mechanisms 3 are electrically connected to the external controller through connecting lines respectively, and the furnace door truss 2 located on one side of the winding mechanism 3 is also movably installed with a guide wheel 4, and both sides of the furnace door truss 2 are fixedly installed with limiting rails 5, and the furnace door 6 is movably installed between the two limiting rails 5, and the limiting rails 5 located on both sides of the furnace door 6 are respectively provided with offset mechanisms 7, and the offset mechanism 7 comprises two mounting seats 8, and the two mounting seats 8 are respectively fixedly installed at the front ends of the corresponding limiting rails 5, and an offset block 9 is fixedly installed in the mounting seat 8, and a connecting beam 10 is movably installed between the two offset blocks 9.

[0021] like Figure 1 As shown, a steel cable is wound around the front end of the winding mechanism 3, and one end of the steel cable is passed around the guide wheel 4 and fixedly installed in the corresponding lifting ear at the upper end of the furnace door 6;

[0022] like Figure 2-Figure 3 As shown, the mounting seat 8 is a C-shaped structure, two fixed shafts 12 are fixedly installed in the mounting seat 8, and the two mounting seats 8 are respectively placed above and below the front end of the limiting track 5. Two plug holes 13 are provided in the offset block 9, and a pressure block 14 is fixedly installed on one side of the offset block 9. The offset block 9 is inserted and installed in the corresponding mounting seat 8 through the plug hole 13. The fixed shaft 12 located between one side of the mounting seat 8 and the offset block 9 is also provided with a compression spring 15. The offset block 9 is inserted and installed in the mounting seat 8 and cooperates with the setting of the compression spring 15. A force displacement and automatic reset function of the pressure block 14 can be realized, and a convex block 16 is fixedly installed at the middle position of the front end of the connecting beam 10;

[0023] like Figure 2-Figure 4As shown, push rods 11 are fixedly installed on both sides of the front end of the furnace door 6. The push rods 11 are L-shaped structures, and the furnace door 6 is inserted and installed between the two limit rails 5. One end of the push rod 11 applies pressure to the protrusion 16. Through the arrangement of the push rod 11, after the furnace door 6 closes the tempering furnace body 1, the connecting beam 10 and the protrusion 16 as well as the offset block 9 and the pressure block 14 can further apply pressure to the furnace door 6 toward the furnace opening of the tempering furnace body 1, thereby improving the sealing effect after the furnace door 6 closes the furnace opening of the tempering furnace body 1.

[0024] It should be noted that the utility model is a tempering furnace door.
