Technical Field

[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a material platform structure for a vertical vacuum heat treatment furnace. Background Technology

[0002] Currently, the material platform in vertical vacuum heat treatment furnaces and single-chamber furnaces is mostly an integrated unit, fixed to the bottom furnace door and opening and closing with the door. When loading materials into the vacuum heat treatment furnace, the furnace door generally opens to one side. To ensure that the material platform does not interfere with loading, the furnace door needs to be fully opened, which occupies a large amount of space outside the equipment, requiring more installation space to be reserved for the equipment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a material platform structure for a vertical vacuum heat treatment furnace.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[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] like Figures 1-3As shown, a material platform structure for a vertical vacuum heat treatment furnace includes a furnace bed support 1 and a furnace bed support 2, which are arranged opposite to each other. The furnace bed support 1 and the furnace bed support 2 are assembled to form an integral material platform. A molybdenum furnace bed 16 is installed on both the furnace bed support 1 and the furnace bed support 2. Insulation components 1 3 and 2 4 are respectively installed on the furnace bed support 1 and the furnace bed support 2. The insulation components 1 3 and the insulation components 2 4 are provided with through holes 21 for the molybdenum furnace bed 16 to pass through. The furnace bed support 1 and the furnace bed support 2 2 are also included as a driving mechanism, which can drive the furnace bed support 1 and the furnace bed support 2 2 to move closer or further apart. The drive mechanism can drive the furnace bed support 1 and the furnace bed support 2 to move away from each other, so that the material platform can open and allow the workpiece to rise into the heat treatment furnace. After rising into position, the drive mechanism will drive the furnace bed support 1 and the furnace bed support 2 to move closer together, so that the material platform is located at the bottom of the workpiece, thus supporting the workpiece.

[0019] Furthermore, connecting blocks 12 and 13 are respectively connected to the same side of the hearth support component 1 and the hearth support component 2. The driving mechanism includes a support wheel 7, a driving sprocket 8, and a driven sprocket 10. The support wheel 7 is drivenly connected to the driving sprocket 8. A chain 9 is wound around the driving sprocket 8, and both ends of the chain 9 are respectively connected to one side of the connecting block 12 and the connecting block 23. A chain 11 is wound around the driven sprocket 10, and both ends of the chain 11 are respectively connected to the other end of the connecting block 12 and the connecting block 23. The chain 9 and the chain 11 are connected through the connecting blocks 12 and 13. The support wheel 7 can directly drive the driving sprocket 8 to rotate, which in turn drives the driven sprocket 10 to rotate. The driving sprocket 8 and the driven sprocket 10 act on the chain 9 and the chain 11 respectively, causing them to move, thereby causing the connecting blocks 12 and the connecting block 23 to move in opposite directions.

[0020] Furthermore, it also includes parallel support rails 6 and positioning rail 20, with hearth support component 1 and hearth support component 2 located between them. Support block 2 17 is connected to the side of hearth support component 1 and hearth support component 2 near positioning rail 20. A grooved wheel 18 is rotatably mounted on support block 2 17, located on positioning rail 20. A portion of positioning rail 20 is located within the groove of the grooved wheel 18. Positioning rail 20 acts as a limiter when the grooved wheel 18 moves, allowing the grooved wheel 18 to move along positioning rail 20. Support block 5 is connected to the side of hearth support component 1 and hearth support component 2 near support rail 6. Support wheel 7 is rotatably mounted on support block 5, located on support rail 6. Support rail 6 provides support when support wheel 7 moves. Positioning rail 19 is provided above positioning rail 10. Positioning rail 19 is parallel to positioning rail 10. Grooved wheel 18 is located between positioning rail 19 and positioning rail 10. Positioning rail 19 and positioning rail 10 work together to limit the vertical movement of grooved wheel 18, ensuring the smooth movement of grooved wheel 18. This ensures that furnace bed support 1 and furnace bed support 2 will not deviate during movement, and that furnace bed support 1 and furnace bed support 2 can be correctly spliced.

[0021] Furthermore, the insulation component 3 has a groove 22 on the side near the insulation component 4, and the insulation component 4 has a protrusion 23 that cooperates with the groove 22 on the side near the insulation component 3, so as to achieve heat insulation at the connection.

[0022] The surfaces of insulation component 3 and insulation component 4 are covered with hard felt to achieve a good insulation effect.

[0023] Furthermore, it also includes several tension sprockets 14 and 25. Chain 9 is arranged to bypass tension sprocket 14, and chain 21 is arranged to bypass tension sprocket 25. Tension sprocket 14 and tension sprocket 25 are used to tension chain 9 and chain 21 respectively, so that the driving sprocket 8 and the driven sprocket 10 can normally drive chain 9 and chain 21 to move.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
