Abstract
Description
Technical Field
[0001] The present invention belongs to the field of heat treatment of tungsten-molybdenum alloys, and particularly relates to a high-temperature heat treatment device for producing tungsten-molybdenum alloy components. Background Art
[0002] Tungsten-molybdenum alloy is an alloy material composed of two metal elements, tungsten and molybdenum. It is mainly used in the electronic industry, high-temperature industry, and chemical industry. In the high-temperature industry, tungsten-molybdenum alloy can be made into tungsten-molybdenum alloy heating rods. The tungsten-molybdenum alloy heating rods have a high melting point and good high-temperature resistance, so they can work stably in a high-temperature environment, efficiently convert electrical energy into heat energy, provide a uniform high-temperature environment in the furnace, and meet the process requirements of metal melting, ceramic sintering, etc.
[0003] After the tungsten-molybdenum alloy heating rods are formed, annealing treatment is required to improve their own structural stability. When the existing high-temperature heat treatment annealing equipment heats the tungsten-molybdenum alloy heating rods, generally there is a large heating chamber inside the equipment. Usually, all the tungsten-molybdenum alloy heating rods are vertically fixed in the heating chamber through a limiting component, and adjacent two tungsten-molybdenum alloy heating rods are separated. However, the above method will cause the circumferential surface of the tungsten-molybdenum alloy heating rods to contact the limiting component, resulting in uneven heating of the area where the tungsten-molybdenum alloy heating rods contact the limiting component, thus having a certain impact on both the heat treatment quality and efficiency of the tungsten-molybdenum alloy heating rods.
[0004] Secondly, all the tungsten-molybdenum alloy heating rods are distributed in a matrix in the heating chamber. However, the heat source of the heating chamber is generally installed on the side wall. The tungsten-molybdenum alloy heating rods at the edge of the matrix will have a situation where the side close to the heat source heats up fast and the side far from the heat source heats up slowly because they are closest to the heat source and in a continuously stationary state at the beginning. As a result, there is a certain difference in the overall temperature of the tungsten-molybdenum alloy heating rods, and it is easy for the tungsten-molybdenum alloy heating rods to have uneven internal heating, making the internal tissue structure change of the tungsten-molybdenum alloy heating rods inconsistent during the annealing process, further affecting the heat treatment quality and efficiency of the tungsten-molybdenum alloy heating rods.

Detailed implementation manners
[0027] The following Figure 1 - Figure 9 further elaborates on the present invention in conjunction with the attached drawings.
[0028] Please refer to Figure 1 and Figure 2 for a high-temperature heat treatment device for producing tungsten-molybdenum alloy components, which includes a box body 1 with an open structure on the front side. A sealing door is provided at the opening of the box body 1. Heaters 2 are provided on the inner walls of the left and right sides and the rear side of the box body 1. A gas conveying pipe fitting 3 is also provided on the box body 1. A positioning frame 4 is slidably arranged in the front and rear directions inside the box body 1. A positioning mechanism 5 for batch-fixing tungsten-molybdenum alloy heating rods is jointly arranged between the positioning frame 4 and the box body 1. A driving mechanism 6 is jointly connected between the positioning mechanism 5 and the gas conveying pipe fitting 3.
[0029] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The gas conveying pipe fitting 3 includes an intake pipe 31 and two outlet pipes 32. The intake pipe 31 is fixedly arranged on the left front side of the box body 1. The two outlet pipes 32 are fixedly arranged on the upper inner wall of the box body 1 and are symmetrically distributed left and right. One ends of the intake pipe 31 and the outlet pipes 32 are connected to an external gas supply device for storing inert gas.
[0030] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 8 A base 7 is fixedly arranged on the lower inner wall of the box body 1. Guide seats 8 with an inverted L-shaped cross-section are fixedly arranged at the left and right edge positions on the upper side of the base 7. Guide strips 9 are fixedly connected to the lower sides of the left and right side walls of the positioning frame 4. The guide strips 9 are in sliding contact with the corresponding guide seats 8.
[0031] During specific operation, the positioning frame 4 can cooperate with the positioning mechanism 5 to vertically fix the tungsten-molybdenum alloy heating rod on the positioning frame 4, and ensure that the peripheral side wall of the tungsten-molybdenum alloy heating rod will not be blocked during the fixing process and cannot contact the external air, which may affect heat transfer. During the heat treatment process, the gas delivery pipe fitting 3 is connected to an external gas supply device that stores inert gas. The external gas supply device sends the inert gas into the box body 1 through the inlet pipe 31, and at the same time, the inert gas inside the box body 1 can be extracted through the outlet pipe 32 and then sent back into itself. In this way, the inert gas is circulated into and out of the box body 1 to create a relatively stable environment inside the box body 1. During the continuous circulation of the inert gas, the inert gas discharged into the box body 1 can provide driving force for the driving mechanism 6, enabling the driving mechanism 6 to cyclically control the rotation of the tungsten-molybdenum alloy heating rod located at the edge of the positioning frame 4 and close to the heater 2, so that the tungsten-molybdenum alloy heating rod at this position is uniformly heated as a whole during the initial heating, thereby improving the heat treatment quality of the tungsten-molybdenum alloy heating rod.
[0032] Refer to Figure 5 and Figure 8 , the positioning frame 4 includes two flat plates 41 symmetrically distributed up and down. Two guiding bars 9 are respectively fixedly arranged on the left and right side walls of the lower flat plate 41. The lower flat plate 41 is connected to the output end of the inlet pipe 31. Four connecting columns 42 are fixedly arranged between the two flat plates 41, and the four connecting columns 42 are respectively distributed at the four corners of the flat plates 41.
[0033] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , the positioning mechanism 5 includes several groups of positioning piece groups 51 arranged on the positioning frame 4 in a matrix distribution. The positioning piece group 51 includes multiple positioning pieces that are slidably connected to the upper side of the positioning frame 4 and have an arc-shaped structure. A positioning cavity with an upward opening is formed between the positioning pieces in the same group. The lower sides of all the positioning pieces are commonly fixedly connected to the same sliding plate 52. The sliding plate 52 is slidably arranged between the upper and lower flat plates 41. Support components 53 are commonly connected between the four corners of the sliding plate 52 and the positioning frame 4. A limiting plate 54 that is slidably connected up and down in the box body 1 is arranged above the positioning frame 4. A pressing component 55 is commonly arranged between the upper inner wall of the box body 1, the limiting plate 54, and the sliding plate 52. A number of arc-shaped sliding holes corresponding to the positioning pieces are formed on the surface of the upper flat plate 41, and the positioning pieces are slidably connected to the corresponding sliding holes.
[0034] Refer to Figure 5 and Figure 6, the supporting component 53 includes a first guiding column 531. The first guiding column 531 is fixedly arranged between the closer sides of the two flat plates 41. The upper end of the first guiding column 531 slidably penetrates through the sliding plate 52, and a first spring 532 sleeved outside the first guiding column 531 is connected between the lower end surface of the first guiding column 531 and the sliding plate 52.
[0035] Refer to Figure 3 , Figure 5 and Figure 7 , the pressing component 55 includes a connecting plate 551 in an X-shaped structure. A screw rod 552 with a handle at the lower end is threadedly connected to the middle position of the connecting plate 551. The upper end of the screw rod 552 is rotatably connected to the upper inner wall of the box body 1. Two symmetrically arranged supporting plates 553 are fixedly arranged on the connecting plate 551. The air outlet pipe 32 vertically and slidably penetrates through the corresponding supporting plates 553. Four lower sides of the four corners of the connecting plate 551 are fixedly connected with second guiding columns 554. The lower ends of the second guiding columns 554 slidably penetrate through the limiting plate 54. A second spring 555 sleeved outside the corresponding second guiding column 554 is connected between the upper side of the limiting plate 54 and the lower side of the connecting plate 551. Jacks 556 are fixedly arranged on the upper side of the sliding plate 52 at positions directly below the second guiding columns 554. The upper ends of the jacks 556 slidably penetrate through the upper sides of the upper flat plates 41, and docking plates 557 are fixedly connected to the upper ends of the jacks 556 and the lower ends of the second guiding columns 554.
[0036] During specific operation, in order to facilitate quickly placing the tungsten-molybdenum alloy heating rod vertically on the positioning frame 4, first slide the positioning frame 4 out of the box body 1 for loading. Then directly insert the lower end of the tungsten-molybdenum alloy heating rod into the positioning cavity formed by the corresponding positioning piece groups 51, so that the tungsten-molybdenum alloy heating rod can be vertically placed on the positioning frame 4. Insert all the tungsten-molybdenum alloy heating rods in sequence. These tungsten-molybdenum alloy heating rods are distributed in a matrix on the positioning frame 4 and there is a certain gap between them. Then push the positioning frame 4 into the box body 1.
[0037] In order to avoid the problem that the positioning piece adheres to the surface of the tungsten-molybdenum alloy heating rod and causes uneven local heating, after the positioning frame 4 is pushed into the box body 1, by rotating the screw rod 552, the connecting plate 551 moves downward to drive the lower limiting plate 54 to move downward and at the same time drive the second guiding column 554 to move downward. The limiting plate 54 moves downward to fit with the upper end surface of the tungsten-molybdenum alloy heating rod, and presses and fixes the tungsten-molybdenum alloy heating rod from the upper end. After that, the limiting plate 54 stops moving, and the connecting plate 551 and the second guiding column 554 continue to move downward relative to the limiting plate 54, and the second spring 555 contracts. The second guiding column 554 will push the jack 556 through the docking plate 557 to make the sliding plate 52 move downward. The sliding plate 52 will drive all the positioning piece groups 51 to move downward. Finally, the upper side of the positioning piece group 51 will move downward to be flush with the upper side surface of the positioning frame 4 (such as Figure 7As shown, it no longer adheres to the surface of the corresponding tungsten-molybdenum alloy heating rod. At this time, the tungsten-molybdenum alloy heating rod maintains a vertical posture on the upper side of the positioning frame 4 under the pressure applied by the upper limiting plate 54. There is no obstruction or contact around the tungsten-molybdenum alloy heating rod, so as to ensure uniform heat transfer.
[0038] Refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 8 and , the driving mechanism 6 includes a plurality of first turntables 61 rotatably arranged on the upper side of the upper flat plate 41. The upper end surface of the first turntable 61 is flush with the upper end surface of the upper flat plate 41. The plurality of first turntables 61 are distributed in a U-shape around the upper side edge of the upper flat plate 41. A connecting shaft 62 is fixedly arranged on the lower side of the upper first turntable 61. The connecting shaft 62 is slidably connected with the sliding plate 52 and rotatably connected with the lower flat plate 41. A vane assembly 63 located between the sliding plate 52 and the lower flat plate 41 is fixedly arranged on the connecting shaft 62. The vane assembly 63 is composed of a plurality of vanes distributed circumferentially along the connecting shaft 62. A second turntable 64 is rotatably arranged at the position corresponding to the lower first turntable 61 on the lower side of the limiting plate 54. The lower end surface of the second turntable 64 is flush with the lower surface of the limiting plate 54.
[0039] Refer to Figure 5 、 Figure 6 、 Figure 8 and Figure 9 and , an air delivery channel 10 is opened inside the lower flat plate 41. A plurality of air nozzles 11 are fixedly arranged on the upper side of the lower flat plate 41 near each vane assembly 63. The air nozzles 11 are inclined and aligned with the corresponding vane assembly 63. An air delivery pipe 12 communicated with the air delivery channel 10 is arranged on the front side of the upper end surface of the lower flat plate 41. The air delivery pipe 12 is threadedly connected with the air inlet pipe 31, and the connection part is sealed by existing technical means. The lower end surface of the vane is slightly higher than the uppermost end surface of the air nozzle 11, and the air nozzle 11 will not obstruct the vane during rotation.
[0040] Refer to Figure 9 and , the air delivery channel 10 includes an air cavity opened inside the lower flat plate 41 and having a rectangular structure. A pressurizing cavity corresponding to the air nozzle 11 one by one and having a frustum structure is opened on the upper inner wall of the air cavity.
[0041] Refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9, during specific operation, when the tungsten-molybdenum alloy heating rod is vertically fixed on the positioning frame 4 through the limiting plate 54, the lower end of the tungsten-molybdenum alloy heating rod located at the edge of the positioning frame 4 and close to the position of the internal heater 2 of the box body 1 abuts against the upper end of the corresponding first turntable 61, and the upper end abuts against the lower end of the corresponding second turntable 64, so that the tungsten-molybdenum alloy heating rods at these positions can rotate subsequently. When the external inert gas supply device sends gas into the gas transmission channel 10 through the air inlet pipe 31 at a sufficient speed and pressure, the gas transmission channel 10 can first pass the gas through the pressurizing chamber and then discharge it through the air nozzle 11 and blow it on the corresponding vane, so that the vane can rotate. At the same time, the inert gas is extracted through the upper air outlet pipe 32 to avoid excessive pressure in the box body 1. In this way, through the vane driving the connecting shaft 62 to rotate, the connecting shaft 62 can drive the upper first turntable 61 to rotate, and then drive the tungsten-molybdenum alloy heating rod in contact with the upper end of the first turntable 61 to rotate, so that the tungsten-molybdenum alloy heating rod in the area close to the heater 2 undergoes heat treatment in a rotating dynamic state, ensuring more uniform heat transfer of the tungsten-molybdenum alloy heating rod.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
