Description

Technical Field

[0001] The utility model relates to the technical field of vacuum furnaces, in particular to a high-performance vacuum furnace. Background Art

[0002] A vacuum furnace is a furnace that uses a vacuum system (which is carefully assembled from components such as a vacuum pump, a vacuum measuring device, and a vacuum valve) to discharge some of the material in the furnace cavity, making the pressure in the furnace cavity less than a standard atmospheric pressure. The space in the furnace cavity is thus in a vacuum state. This is a vacuum furnace.

[0003] During the use of vacuum furnace equipment, the furnace body is placed flat. Since the overall body of the vacuum furnace is relatively large, when taking and placing objects, especially when the workpiece is heavy, multiple people are required to lift it into the vacuum furnace. There are various coils inside the vacuum furnace, which makes it inconvenient for workers to enter and exit the furnace body, resulting in inconvenience in loading and unloading. In this regard, we proposed a high-performance vacuum furnace. Utility Model Content

[0022] The lifting mechanism 12 includes a base 13 and a lifting plate 18. The base 13 is fixedly mounted on the support base 2. A groove 14 is opened on the top wall of the base 13. A servo motor 15 is fixedly mounted on the outer wall of the base 13. The output end of the servo motor 15 is transmission-connected with a bidirectional screw rod 16. The bidirectional screw rod 16 is rotatably mounted on the base 13. Two moving rods 17 are threadedly connected to the bidirectional screw rod 16. The two moving rods 17 are slidably connected in the groove 14. The servo motor 15 can drive the bidirectional screw rod 16 to rotate, so that the two moving rods 17 move toward or away from each other in the groove 14.

[0023] The lifting plate 18 is arranged above the base 13, and two pairs of connecting rods 19 are rotatably installed on the bottom wall of the lifting plate 18. The ends of the two pairs of connecting rods 19 away from the lifting plate 18 are rotatably installed on two moving rods 17 respectively. When the two moving rods 17 move, they can drive the two pairs of connecting rods 19 to flip, so as to push and pull the lifting plate 18, and drive the lifting plate 18 to rise and fall.

[0024] The front and rear side walls of the support plate 8 are both provided with locking rods 20, and a plurality of plug rods 21 are fixedly welded on the locking rods 20. The plug rods 21 are slidably connected to the support plate 8. The front and rear side walls of the lifting plate 9 are both provided with slots 22 adapted to the plug rods 21. The two locking rods 20 are both installed with locking studs 23. The lifting plate 9 can be fixed to the support plate 8 by plugging and fitting the plug rods 21 into the slots 22.

[0025] Two symmetrically arranged positioning rods 24 are fixedly welded on the top wall of the support plate 8, and two vertical rods 25 are fixedly welded on the top wall of the lifting plate 9. Positioning blocks 26 are fixedly welded on the top ends of the two vertical rods 25. The two positioning blocks 26 are respectively slidably connected to the two positioning rods 24. Through the cooperation of the arranged vertical rods 25 and the positioning blocks 26 with the positioning rods 24, it can be ensured that the lifting plate 9 will not tilt during lifting, thereby ensuring the stability of the lifting plate 9.

[0026] Working principle: When the utility model is in use, the hydraulic rod 7 can drive the moving seat 6 to slide on the guide rod 5 to open and close the furnace cover 3. When the furnace cover 3 is opened and closed, the support plate 8 can be driven to move on the support frame 10 to extend out or be retracted into the inner cavity of the furnace body 1. When loading and unloading, the support plate 8 can be pulled out of the inner cavity of the furnace body 1, and the loading and unloading operations can be performed outside the furnace body 1. The space is large and the operation freedom is high, which improves the convenience of loading and unloading. When it is necessary to place a heavier workpiece, a plurality of plug rods 21 can be pulled out, and then the lifting plate 9 can be lowered to the lifting plate 18 below, which reduces the lifting height when placing a heavy workpiece, making it easier to place a heavy workpiece. After the heavy workpiece is placed on the lifting plate 9, the servo motor 15 is started to drive the lifting plate 18 to move upward, so that the lifting plate 9 rises to be flush with the support plate 8, and then the plug rod 21 is inserted to limit and fix the lifting plate 9 and the support plate 8, and then the furnace cover 3 can be closed to drive the support plate 8 to be retracted into the inner cavity of the furnace body 1.
