Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment furnaces, and in particular relates to a heat storage type thermal cycle heat treatment furnace. Background Art

[0002] With the rapid development of the economy, the output of some metal products is increasing. In order to improve the quality of metal products, they are generally heat treated. By means of heating, insulation and cooling, the expected effects and performance can be obtained. This generally requires the use of a heat treatment furnace. By placing the workpiece in the furnace, the workpiece can be heated to achieve the purpose of heat treatment.

[0003] Existing heat treatment furnaces are generally provided with furnace doors. When in use, the furnace door needs to be opened, and then the workpieces are placed inside, and the workpieces are baked through the internal resistance heating components to achieve the purpose of heat treatment. However, after the workpieces in the furnace are heated, the furnace door needs to be opened, and the heated workpieces inside are taken out, and then the next batch of workpieces that need to be heated are put in. When the furnace door is opened, the hot air inside the furnace body contacts the outside air through the furnace door, which is easy to cause heat loss, thereby increasing resource consumption. In view of this, we propose a heat storage type thermal cycle heat treatment furnace. Utility Model Content

[0006] Based on the above structure, the telescopic rod drives the inclined block to be inserted into the interior of the fixed box, and the inclined block squeezes the sliding block. Under the action of the inclined surface, the sliding block moves upward, so that the heating box enters the interior of the inner shell, and the workpiece inside the heating box is heated by multiple heating tubes. When the workpiece is taken out of the inner shell, the telescopic rod drives the heating box and the inclined block to be pulled out from the interior of the inner shell. When the inclined block leaves the sliding block, the spring drives the sliding block to rebound and blocks the jack on the fixed box, thereby isolating the hot air inside the outer shell from the outside air, thereby achieving the effect of preventing the hot air inside the furnace body from contacting the outside air, thereby solving the problem that the hot air inside the existing furnace body contacts the outside air through the furnace door, which easily leads to heat loss and thus increases resource consumption.

The telescopic rod drives the inclined block to be inserted into the interior of the fixed box. The inclined block squeezes the sliding block. Under the action of the inclined surface, the sliding block moves upward, so that the heating box enters the interior of the inner shell, and the workpiece inside the heating box is heated by multiple heating tubes. When the workpiece is taken out of the inner shell, the telescopic rod drives the heating box and the inclined block to be pulled out from the interior of the inner shell. When the inclined block leaves the sliding block, the spring drives the sliding block to rebound and blocks the jack on the fixed box, so that the hot air inside the inner shell is isolated from the outside air, thereby preventing the hot air inside the furnace body from contacting with the outside air, thereby solving the problem that the hot air inside the existing furnace body contacts with the outside air through the furnace door, which easily leads to heat loss and increases resource consumption.
