Detailed Description
As shown in figures 1 and 2, the atmosphere quenching hot pressing work station comprises an atmosphere protection type glove box 1 and a high-temperature sintering furnace 2 positioned on the left side of the atmosphere protection type glove box, wherein the inner cavity of the glove box 1 is communicated with a hearth of the high-temperature sintering furnace 2. A quartz furnace tube 2.2 which controls the heating time and the heating temperature through an electric cabinet 2.1 is arranged in the hearth of the high-temperature sintering furnace 2. In order to avoid the overhigh temperature of the glove box 1, a water-cooling sealing flange 3 is arranged at the connecting section of the glove box 1 and the high-temperature sintering furnace 2. The one end that is close to high temperature sintering stove 2 in the glove box 1 is installed horizontal sliding seat 4.1, and the rotation mounting groove in-connection on this horizontal sliding seat 4.1 has rotation push rod 4.2, and rotation push rod 4.2 can remove about along with horizontal sliding seat 4.1, can also carry out axial rotation under external force promotes to carry out axial through rotatory torsional spring 4.3 and reset. The head of the rotating push rod 4.2 is provided with a tungsten crucible 4.4 for containing samples, and the middle part is provided with a sealing plug 4.5 for plugging the hearth of the high-temperature sintering furnace 2. A movable material receiving copper groove 5 connected with the trolley is arranged below the horizontal sliding seat 4.1, and a cooling base 6 made of a water-cooling copper sleeve is contacted with the lower side of the material receiving copper groove 5. The other end of the glove box 1 far away from the high-temperature sintering furnace is provided with a heating and pressurizing testing mechanism 7. The heating and pressurizing testing mechanism 7 comprises a supporting frame 7.1, a horizontal sliding plate 7.3 is connected to left and right upright posts of the supporting frame 7.1 through a guide sliding sleeve 7.2, the horizontal sliding plate 7.3 is controlled to lift by a pedal hydraulic oil cylinder 7.4, a heating and pressurizing furnace 7.5 is installed between the horizontal sliding plate 7.3 and a top plate of the supporting frame 7.1, and a corundum upper pressing post 7.6 fixedly connected to the top plate of the supporting frame 7.1 and a corundum lower pressing post 7.7 fixedly connected to the horizontal sliding plate 7.3 penetrate through a furnace wall of the heating and pressurizing furnace 7.5 and extend into a hearth. A graphite mould 7.8 is arranged in the hearth. In addition, the heating and pressurizing test mechanism 7 is also provided with a touch control screen 7.9 and a digital display pressure gauge 7.10.
The utility model comprises two procedures of quenching and cooling and hot-pressing measurement when in use.
Firstly, the rotating push rod 4.2 is pulled to the rightmost end, a sample is placed in the tungsten crucible 4.4, then the rotating push rod 4.2 is pushed to the leftmost end, at the moment, the tungsten crucible 4.4 is positioned in the hearth of the high-temperature sintering furnace 2, and the sealing plug 4.5 just blocks the hearth of the high-temperature sintering furnace 2, so that heat is prevented from being dissipated outwards. Then, the quartz furnace tube 2.2 starts to be heated to a certain temperature, the sample in the tungsten crucible 4.4 is in a molten liquid state, at this time, the rotating push rod 4.2 is rapidly pulled out, meanwhile, the rotating push rod 4.2 is rotated to enable the tungsten crucible 4.4 to turn over by 100 degrees and pour the molten sample into the copper receiving groove 5, and then the rotating push rod 4.2 automatically returns to the original position under the action of the rotating torsion spring 4.3 to enable the tungsten crucible 4.4 to be kept horizontal. The cooling base 6 is in contact with the material receiving copper groove 5, so that the heat of the sample can be taken away quickly, and the purpose of quick cooling is achieved. After the sample is cooled, the trolley is pulled rightwards, so that the material receiving copper groove 5 leaves the horizontal sliding seat 4.1, and the cooled sample in the material receiving copper groove 5 is taken out.
