Tempering furnace with high reliability

Abstract

The invention relates to a tempering furnace with high reliability. The tempering furnace comprises a main body, a door body and a workbench and further comprises a circulating mechanism and a sealing mechanism. The circulating mechanism comprises a driving assembly, an air inlet pipe, an air outlet pipe, a connecting assembly, two circulating pipes, two branch pipes and two jacking assemblies. The sealing mechanism comprises a rubber water stop strip, a water box, a water inlet pipe, a water adding assembly and a connecting pipe. According to the tempering furnace with high reliability, the function that hot air in the main body circularly flows upwards and downwards is achieved through the circulating mechanism, a workpiece on the workbench is evenly heated, and therefore the tempering effect can be improved; and because the expanded rubber water stop strip is used for filling up a gap between the door body and the main body, air leakage between the main body and the door body after long-time use is prevented, hot air in the main body is prevented from being discharged out through a gap during tempering work, workers are prevented from being scalded, meanwhile, the temperature in the main body is prevented from being influenced, and the tempering quality is prevented from being influenced.

Description

technical field [0001] The invention relates to the field of manufacturing and processing metal wire ropes and their products, in particular to a tempering furnace with high reliability. Background technique [0002] The tempering furnace is used for tempering general metal parts in air and quenching, annealing and aging heat treatment for aluminum alloy die-casting parts, pistons, aluminum plates and other light alloy parts. The shell is welded by steel plate and section steel, and the trolley is welded by section steel and steel plate. [0003] After the existing tempering furnace is used for a long time, the door body will be aging, resulting in a gap between the door body and the main body, which will cause the hot air inside the main body to be easily discharged through the gap, which will easily burn the staff and affect the main body. The internal working temperature affects the quality of tempering and reduces the reliability of the existing tempering furnace. Not o...

Problems solved by technology

[0003] After the existing tempering furnace is used for a long time, the door body will be aging, resulting in a gap between the door body and the main body, which will cause the hot air inside the main body to be easily discharged through the gap, which will easily burn the staff and affect the main body. The internal working temperature affects the quality of tempering and reduces the reliability of the existing tempering furnace. Not only that, when the existing tempering furnace is working, because the workpiece is placed inside the main body, the workpiece is heated unevenly , resulting in different properties of the workpiece after heat treatment, thereby reducing the quality of heat-treated products
