Description

Technical Field

[0001] This utility model relates to the field of vacuum tempering furnace technology, specifically a vacuum tempering furnace sealing installation structure. Background Technology

[0002] Vacuum tempering furnaces are important industrial heat treatment equipment. Their main function is to temper metal workpieces in a vacuum environment to improve their microstructure and properties, increasing their hardness, toughness, and wear resistance. During the tempering process, precise control of the vacuum level and temperature within the furnace is crucial for ensuring workpiece quality. Good sealing performance is fundamental to maintaining a stable vacuum environment and accurate temperature field within the furnace.

[0003] When a vacuum tempering furnace is in operation, a stable vacuum environment inside the furnace is the core element to ensure the quality of material heat treatment. However, current vacuum tempering furnaces generally face technical bottlenecks in the loading and unloading process: due to the limitations of the equipment structure, operators must open the furnace door to load and unload materials. This process will cause the vacuum environment inside the furnace to be destroyed instantly. The influx of outside air not only prolongs the time for the equipment to be re-vacuumed and increases energy consumption costs, but may also cause problems such as oxidation and decarburization on the surface of the material. To address this, we propose a sealed installation structure for vacuum tempering furnaces. Utility Model Content

However, current vacuum tempering furnaces generally face technical bottlenecks in the loading and unloading process: due to the limitations of the equipment structure, operators must open the furnace door to complete the loading and unloading of materials. This process will cause the vacuum environment inside the furnace to be destroyed instantly. The influx of outside air not only prolongs the time for the equipment to be re-vacuumed and increases energy consumption costs, but may also cause problems such as oxidation and decarburization on the surface of the materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum tempering furnace sealing installation structure, comprising a furnace body, a connecting cover movably connected to the front of the furnace body, a frame body communicating with the front of the connecting cover, a first sealing plate and a second sealing plate sequentially inserted into the top of the frame body from back to front, a lead screw movably connected to the right side of the front of the connecting cover, a threaded sleeve threadedly connected to the surface of the lead screw, a hollow block fixedly connected to the top of the threaded sleeve, a motor fixedly connected to the right side of the hollow block, a crankshaft fixedly connected to the output end of the motor, an adjusting plate movably connected to the surface of the crankshaft, a connecting frame fixedly connected to one side of the adjusting plate, a connecting pin fixedly connected to one side of the connecting frame, and a vacuum pump connected to the central shaft at the bottom of the frame body via a solenoid valve.

Then the first sealing plate is returned to its original position. Then the lead screw is rotated, the lead screw drives the threaded sleeve to move, the threaded sleeve drives the hollow block to move, which in turn drives the connecting pin to move through the connecting frame, so that the connecting pin moves away from the first sealing plate and inserts into the second sealing plate. Then the height of the second sealing plate is adjusted, and then the material can be removed. The material to be processed is placed at the central axis at the bottom of the inner cavity of the frame. Then the second sealing plate is returned to its original position, and then the vacuum pump and solenoid valve are started to evacuate the inner cavity of the frame.

[0015] 2. In this utility model, the rectangular plate is pulled outward, and then the connecting cover is rotated. The connecting cover moves the sealing gasket, making the sealing gasket in close contact with the furnace body. Then the rectangular plate is released, and the rectangular plate is moved by the tension of the spring.
