[0002] High-temperature molybdenum wire has advantages such as high tensile strength, good high-temperature creep performance, and high recrystallization temperature. After high-temperature annealing and recrystallization, it also has good ductility. Molybdenum wire is mainly used as an electrode wire in wire electrical discharge machining, and it is continuously moved by a high-voltage electric field to cut the workpiece.

[0003] A search revealed Chinese patent publication number CN222336059U, which discloses a hydrogen-protected heating furnace for molybdenum wire processing. This patent uses a first and a second electric telescopic rod to drive the furnace door upwards along the axial direction of the second electric telescopic rod, thereby opening the furnace door. Subsequently, the molybdenum wire rotates to the top of the furnace body, and then the furnace door descends to close. After heating, the furnace door rises again, moving the molybdenum wire away. This device has certain problems: the furnace door needs to be opened and closed frequently when moving the molybdenum wire, causing the high-temperature heated molybdenum wire to come into direct contact with the cold air outside, which may cause the material to become brittle due to a sudden drop in temperature.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a heating furnace for processing molybdenum wire includes a base plate 101. A support cover 102 is fixedly connected to the upper end of the base plate 101. The support cover 102 is located on the rear side of the base plate 101. A fixing box 103 is fixedly installed on the upper end of the support cover 102. A partitioning mechanism is provided on the support cover 102.

[0026] The separation mechanism includes multiple partition plates 401, which are arranged at equal intervals and slidably connected to the front end of the support cover 102. The partition plates 401 divide the support cover 102 into multiple chambers. Two auxiliary chambers are symmetrically arranged on both sides of the support cover 102. A heating chamber is provided inside the support cover 102, located between the symmetrical auxiliary chambers. A transmission mechanism is provided at the front end of the partition plates 401. In use, the transmission mechanisms on both sides drive the partition plates 401 at both ends to move forward, placing the molybdenum wire in the auxiliary chambers on both sides and closing the partition plates 401 at both ends. Then, after the heating chamber is heated to the target temperature, the partition plate 401 on one side of the heating chamber is driven to open, and the molybdenum wire on the same side enters the heating chamber. After the molybdenum wire is heated, the partition plate 401 on the same side is driven to open, and the molybdenum wire moves to the auxiliary chamber for slow cooling. During the process, the heat is always stored in the support cover 102, avoiding the direct removal of the heated molybdenum wire from the support cover 102, which could cause the material to become brittle.

[0027] The transmission mechanism includes a threaded rod 402, which is threadedly connected to the lower end of the partition plate 401. The front end of the threaded rod 402 is rotatably connected to the base plate 101. A power motor 403 is fixedly installed at the front end of the base plate 101. The output shaft of the power motor 403 is fixedly connected to the threaded rod 402. The power motor 403 drives the threaded rod 402 to rotate, causing the partition plate 401 to move on the threaded rod 402.

[0028] The front end of the support cover 102 has multiple sliding grooves 201. The threaded rod 402 is rotatably connected to the rear end of the sliding groove 201. The partition plate 401 is slidably connected to the sliding groove 201. A sealing strip is fixedly provided between the sliding groove 201 and the partition plate 401.

[0029] The lower end of the fixed box 103 has a movable groove 202, which is connected to the inside of the support cover 102. A moving mechanism is provided inside the movable groove 202.

[0030] The moving mechanism includes two cylinders 301, which are symmetrically fixedly connected to both sides of the fixed box 103. The output shaft of the cylinder 301 is fixedly connected to a moving block 302. The moving block 302 is slidably connected to the moving groove 202. The cylinder 301 drives the moving block 302 to move, so that the moving block 302 drives the molybdenum wire to move.

[0031] The lower end of the movable block 302 is fixedly connected to a support frame 501, and the support frame 501 is provided with limiting components on both the front and rear sides.

[0032] The limiting component includes multiple limiting protrusions 502, which are threaded onto the support frame 501. In use, the molybdenum wire is sleeved on the limiting protrusion 502. When heating molybdenum wires of different shapes, the limiting protrusion 502 can be rotated to disengage from the support frame 501 and replace it with a suitable limiting component.

[0033] Working principle: During use, the molybdenum wire is sleeved on the limiting protrusion 502. When heating molybdenum wires of different shapes, the limiting protrusion 502 can be rotated to disengage from the support frame 501 and replace it with a suitable limiting component. Then, the threaded rod 402 is driven to rotate by the power motors 403 on both sides, driving the partition plates 401 at both ends to move forward on the threaded rod 402. Then, the molybdenum wire is placed in the auxiliary cavities on both sides and the partition plates 401 at both ends are closed. After the heating cavity is heated to the target temperature, the partition plate 401 on one side of the heating cavity is driven to open. The cylinder 301 drives the moving block 302 to move, so that the moving block 302 carries the molybdenum wire on the same side into the heating cavity. After the molybdenum wire is heated, the partition plate 401 on the same side is driven to open, and the molybdenum wire moves to the auxiliary cavity for slow cooling. During the process, the heat is always stored in the support cover 102 to reduce heat loss and avoid directly removing the heated molybdenum wire from the support cover 102, which would cause the material to become brittle.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
