Description

Technical Field

[0001] This utility model relates to the field of tungsten and molybdenum material processing technology, specifically a segmented temperature-controlled annealing furnace for tungsten and molybdenum material processing. Background Technology

[0002] Tungsten and molybdenum are two high-temperature resistant metals. Other refractory metals include niobium, zirconium, titanium, and hafnium. Tungsten, molybdenum, and their alloys have wide industrial applications due to their excellent thermal and electrical conductivity, low coefficient of thermal expansion, high-temperature strength, low vapor pressure, and wear resistance. In the processing of tungsten and molybdenum materials, annealing furnaces are used to modify their internal structure and thus improve their physical and chemical properties.

[0003] In annealing furnaces, tungsten-molybdenum materials are heated using internal heating tube assemblies to alter their internal microstructure through high temperatures, followed by cooling in a cooling chamber. However, existing annealing furnaces lack the ability to automatically load and unload tungsten-molybdenum materials and ensure their stability during movement within the furnace. Therefore, a segmented temperature-controlled annealing furnace for processing tungsten-molybdenum materials is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a segmented temperature-controlled annealing furnace for processing tungsten and molybdenum materials, so as to solve the problems mentioned in the background art, where existing annealing furnaces are inconvenient to automatically load and unload tungsten and molybdenum materials during use, and at the same time, it is inconvenient to ensure the stability of tungsten and molybdenum materials during movement within the annealing furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented temperature-controlled annealing furnace for processing tungsten and molybdenum materials, comprising an annealing furnace, wherein the annealing furnace is internally divided into a heating chamber and a cooling chamber by multiple sets of partitions, and the heating chamber is provided with heating tubes inside; the annealing furnace has through holes at both ends, and tungsten and molybdenum materials are inserted into the through holes; the annealing furnace has multiple sets of first support rods on the left side inside, and multiple sets of first ball bearings are embedded in the upper end of the first support rods; the cooling chamber has multiple sets of fixing plates inside, and rollers are inserted between the fixing plates, and the tungsten and molybdenum materials are inserted between the rollers;

[0006] The annealing furnace has a first fixed frame at each of its two ends below, and an electric push rod is provided inside the first fixed frame. The electric push rod has a telescopic arm on one side, and a connecting rod at one end of the telescopic arm. A second fixed frame is provided at the upper end of the connecting rod. A second support rod is provided at each of the two ends below the second fixed frame, and the second support rod is inserted into the first fixed frame. Multiple sets of second ball bearings are embedded in the lower ends of the connecting rod and the second support rod.

[0007] The second fixing frame is equipped with a micro servo motor inside, and one end of the output shaft of the micro servo motor is connected to a bidirectional screw through a coupling. The bidirectional screw is equipped with a sliding rod above it, and movable blocks are inserted at both ends of the bidirectional screw and the sliding rod. Connecting plates are respectively provided above the movable blocks, and limit plates are respectively placed on the opposite sides of the connecting plates. Bolts are inserted through the connecting plates and the limit plates.

[0008] Preferably, the first ball bearing is formed by a tungsten-molybdenum material and a first support rod to form a rotating structure, and the roller shaft is formed by a tungsten-molybdenum material and a fixed plate to form a rotating structure as well.

[0009] Preferably, the second fixed frame, under the action of the electric push rod, forms a horizontal pushing structure with the annealing furnace through the telescopic arm, the second support rod, and the second ball bearing.

[0010] Preferably, the connecting plate, under the action of the micro servo motor, forms a bidirectional limiting sliding structure with the second fixed frame through a bidirectional screw, a slide bar, and a movable block, and the limiting plate forms a spiral locking structure with the connecting plate through bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The first ball bearing of the segmented temperature-controlled annealing furnace for tungsten-molybdenum material processing forms a rotating structure with the first support rod through the tungsten-molybdenum material, and the roller shaft forms a rotating structure with the fixed plate through the tungsten-molybdenum material. Thus, the tungsten-molybdenum material in the annealing furnace can be supported by multiple sets of first ball bearings and roller shafts, thereby ensuring that the tungsten-molybdenum material can move and be annealed normally. The second fixed frame of the device forms a horizontal pushing structure with the annealing furnace through the telescopic arm, the second support rod, the second ball bearing, and the electric push rod. Thus, the two ends of the tungsten-molybdenum material can be automatically loaded and unloaded under the action of the electric push rod, so as to increase the convenience of the annealing process of the tungsten-molybdenum material. The connecting plate of the device forms a bidirectional limiting sliding structure with the second fixed frame through the bidirectional screw, the slide rod, and the movable block under the action of the micro servo motor. The limiting plate forms a spiral locking structure with the connecting plate through bolts. Thus, the two ends of the tungsten-molybdenum material can be squeezed and limited by the relatively moving limiting plate, so as to drive the tungsten-molybdenum material to move automatically in the future.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a segmented temperature-controlled annealing furnace for processing tungsten and molybdenum materials, including an annealing furnace 1. The annealing furnace 1 is divided into a heating chamber and a cooling chamber by multiple sets of partitions inside. The heating chamber is provided with heating tubes 2 inside. The annealing furnace 1 has through holes at both ends, and tungsten and molybdenum materials are inserted into the through holes. The annealing furnace 1 has multiple sets of first support rods 3 on the left side inside. The first support rods 3 have multiple sets of first ball bearings 4 embedded in their upper ends. The cooling chamber has multiple sets of fixing plates 5 inside. Rollers 6 are inserted between the fixing plates 5. Tungsten and molybdenum materials are inserted between the rollers 6.

[0019] Furthermore, the first ball bearing 4 forms a rotating structure with the first support rod 3 through tungsten-molybdenum material, and the roller shaft 6 also forms a rotating structure with the fixed plate 5 through tungsten-molybdenum material. Thus, without affecting the movement of the tungsten-molybdenum material, it can be assisted and supported by multiple sets of first ball bearings 4 and roller shaft 6, thereby ensuring the stability of the tungsten-molybdenum material during processing.

[0020] The annealing furnace 1 has a first fixed frame 7 at both ends below, and an electric push rod 8 is provided inside the first fixed frame 7. The electric push rod 8 has a telescopic arm 9 on one side, and a connecting rod is provided at one end of the telescopic arm 9. A second fixed frame 12 is provided at the upper end of the connecting rod. A second support rod 10 is provided at both ends below the second fixed frame 12, and the second support rod 10 is inserted into the first fixed frame 7. Multiple sets of second ball bearings 11 are embedded in the lower end of the connecting rod and the second support rod 10.

[0021] Furthermore, under the action of the electric push rod 8, the second fixed frame 12 forms a horizontal pushing structure with the annealing furnace 1 through the telescopic arm 9, the second support rod 10, and the second ball bearing 11, thereby ensuring that the limiting component can move horizontally under the action of the electric push rod 8, and thus ensuring that the tungsten molybdenum material can be automatically loaded and unloaded.

[0022] The second fixed frame 12 has a micro servo motor 13 inside, and one end of the output shaft of the micro servo motor 13 is connected to a bidirectional screw 14 through a coupling. The bidirectional screw 14 has a corresponding slide rod 15 above it, and movable blocks 16 are inserted through both ends of the bidirectional screw 14 and the slide rod 15. The movable blocks 16 have connecting plates 17 above them, and limit plates 18 are placed on opposite sides of the connecting plates 17. Bolts 19 are inserted through the connecting plates 17 and the limit plates 18. It should be noted that the electrical equipment and heating tube 2 in this device are connected to the power supply equipment through power cords, and their working status is controlled by a controller to ensure that the device can work normally. The movable blocks 16 are provided with spiral holes and through holes to ensure that the movable blocks 16 can slide within the second fixed frame 12.

[0023] Furthermore, under the action of the micro servo motor 13, the connecting plate 17 forms a bidirectional limiting sliding structure with the second fixed frame 12 through the bidirectional screw 14, the slide bar 15, the movable block 16, and the limiting plate 18 forms a spiral locking structure with the connecting plate 17 through the bolt 19. Thus, the corresponding limiting plate 18 can be installed according to the size of the tungsten molybdenum material, and the tungsten molybdenum material can be squeezed and limited by the relatively moving limiting plate 18.

[0024] Working Principle: In a segmented temperature-controlled annealing furnace used for processing tungsten and molybdenum materials, one end of the tungsten and molybdenum material is first inserted into annealing furnace 1. The micro servo motor 13 at the feed inlet of annealing furnace 1 is then started. The output shaft of the micro servo motor 13 drives a bidirectional screw 14 to rotate via a coupling, and drives a limiting plate 18 to move relative to it via a slide rod 15 and a movable block 16. This allows the limiting plate 18 to compress and limit the tungsten and molybdenum material. Subsequently, an electric push rod 8 is started. The electric push rod 8, via a telescopic arm 9, moves the second fixed frame 12 towards the annealing box 1, thereby automatically feeding the tungsten and molybdenum material. When the other end of the tungsten and molybdenum material moves to the discharge port of annealing line 1, the micro servo motor 13 on the other side is started. The push rod 8 is moved, thereby automatically unloading the other end of the tungsten-molybdenum material using the same principle. The alternating movement of the limiting components on both sides ensures that the tungsten-molybdenum material can be automatically loaded and unloaded, thereby increasing the convenience of the annealing process. During the limiting movement of the tungsten-molybdenum material, the stability of the second fixed frame 12 during the overall movement can be increased by multiple sets of second support rods 10 and second ball bearings 11. During the processing of the tungsten-molybdenum material, it can be further supported by multiple sets of first ball bearings 4 and rollers 6 inside to ensure the stability of the tungsten-molybdenum material during the processing. At the same time, the first ball bearings 4 and rollers 6 can ensure that the tungsten-molybdenum material can move smoothly. This is the usage process of the segmented temperature-controlled annealing furnace for processing tungsten-molybdenum material.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
