Description

Technical Field

[0001] The utility model relates to a material stirring device for a gas suspension furnace in a sealed cavity, belonging to the technical field of position control application of high-temperature melt inside a gas suspension furnace. Background Art

[0002] During the heating process of the sealed cavity air suspension material in the laser heating suspension furnace, the unstable airflow causes the material to adhere to the container wall around the nozzle after melting, deviating from the center position of the nozzle where the laser is focused and heated, making it impossible for the laser to perform gas suspension heating and melting. It is usually necessary to open the sealed cavity cover and relocate the material to the center position of the laser focused nozzle, which greatly reduces the production efficiency. In order to improve production efficiency and ensure quality, it is necessary to have a method that can relocate the material adhered to the nozzle container wall in the sealed cavity to the laser heating center position of the nozzle at high speed and precision. However, most of the existing moving devices simply perform linear pushing motion and cannot push and move the material that is not at the center position of the push rod. This device uses the characteristics of the bellows that can perform 360-degree rotation stirring and compressible deformation to invent a stirring device that can stir the material adhered to the nozzle container wall at different positions and angles with high precision, enter the laser heating focus center of the nozzle, ensure the continuous work of the material in the sealed cavity for laser heating gas suspension, and greatly improve the production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a material stirring device for a gas suspension furnace in a sealed cavity in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a gas suspension furnace material stirring device in a sealed cavity, comprising a stirring rod, a first welding seat, a bellows, a second welding seat, a column groove, a clamping block, an operating bellows head and a sealing ring, wherein a portion of the stirring rod is in sealing sliding contact with the middle portion of the sealing ring located in the second welding seat, and one end of the bellows is sealingly welded to the bottom end of the second welding seat, and the other end of the bellows is welded around a port on one side of the first welding seat, an operating bellows head is installed at the outer end of the stirring rod, and the stirring rod is in an elastically deformable state through the bellows welded between the first welding seat and the second welding seat to form an active operating range.

[0005] Preferably, the bellows is a KF16 welded bellows, the action portion of the bottom end of the stirring rod is conical, and the conical portion of the bottom end of the stirring rod reaches a specified nozzle position by moving.

[0006] Preferably, the middle portion of the first welding seat is a hole structure, and the inner diameter of the hole structure is much larger than the diameter of the stirring rod.

[0007] Preferably, the second welding seat is provided with a column groove, and the column groove is fixedly connected to the surface of the sealing ring.

[0008] Preferably, a pressing block is sealed and mounted on one end of the second welding seat.

[0009] Preferably, the corresponding portion of the stirring rod slides through the middle of the pressing block.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] By utilizing the bellows' 360-degree rotating stirring and compressible deformation movement characteristics, the flexibility of the stirring rod to rotate sideways at will is guaranteed;

[0012] The corrugated head is driven by the side-swinging operation to stir the connected stirring rod in the air-suspended material in the sealed cavity, so that the material deviating from the laser heating focus position can be quickly and accurately returned to the laser heating focus position under the sealed condition, and the air-suspended material can be stably suspended and heated and melted, ensuring the continuous operation of the laser heating gas suspension in the sealed cavity, greatly improving the production efficiency;

[0013] Solve the problem that the gas suspension material in the sealed cavity cannot be heated and melted by gas suspension during high-temperature heating because the melt and the nozzle container wall are adhered to each other, deviating from the center position of laser focusing heating;

[0014] A sealing ring is used to seal one side of the connection between the first welding seat and the stirring rod and combined with a bellows to prevent the airflow inside and outside the laser heating suspension furnace connected thereto from mixing, reducing the purity of the suspension gas, causing oxidation of the material and a decrease in product quality.
