Description

Technical Field

[0001] This utility model belongs to the field of flip-over baffle technology, specifically a flip-over baffle device for intermediate ladle in a vacuum melting gas atomization furnace. Background Technology

[0002] The tundish tilting baffle device used in vacuum melting gas atomization furnaces is a special mechanical device. Its main function is to control the flow and distribution of molten metal during melting and atomization by tilting the baffle. The tundish tilting baffle device typically consists of a baffle body, a tilting mechanism, a drive device, and a control system. The baffle body is generally made of high-temperature and corrosion-resistant materials to ensure stability and durability during the melting process. The tilting mechanism is responsible for realizing the tilting action of the baffle, the drive device provides power, and the control system is used to precisely control the timing and angle of the tilting. Existing tundish tilting baffles lack positioning capabilities, resulting in inaccurate rotation and gaps, which can cause molten metal leakage, leading to poor performance. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tundish turning baffle device for a vacuum melting gas atomization furnace, which effectively solves the problem that the existing tundish turning baffle does not have a positioning effect, resulting in inaccurate rotation and positioning with gaps, thus causing molten metal leakage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tundish tilting baffle device for a vacuum melting gas atomizing furnace, comprising a mounting plate, a servo motor fixedly mounted at the center of the top of the mounting plate, a coupling fixedly mounted at the output end of the servo motor, a shaft fixedly mounted at the bottom of the coupling, a bushing rotatably mounted on the surface of the shaft, the surface of the bushing being fixedly connected to the bottom of the mounting plate via a connecting rod, a connecting plate fixedly mounted at the lower end of the shaft surface, a mica plate fixedly mounted on one side of the connecting plate, a support plate fixedly mounted on one side of the bottom of the mounting plate, a drive motor fixedly mounted on one side of the support plate, a transmission assembly provided at the output end of the drive motor, an insertion rod provided on one side below the mounting plate, and an insertion hole provided at the top of the connecting plate, the transmission assembly being connected to the insertion rod in a transmission manner, and the insertion rod being moved downward and positioned via the transmission assembly when the drive motor is running.

[0005] Preferably, the transmission assembly includes a transmission rod, a positioning strip is rotatably mounted on one side of the upper end of the transmission rod, the top of the positioning strip is fixedly connected to the bottom of the mounting plate, a strip groove is provided at the lower end of the transmission rod, a pushing strip is provided on one side of the shaft, an opening is provided at one end of the pushing strip, a transmission pin is fixedly installed inside the opening, the lower end of the transmission rod is sleeved on the surface of the transmission pin through the strip groove, and a slider is fixedly installed at the bottom of the pushing strip.

[0006] Preferably, the inclined surface of the other end of the push bar is closely attached to a roller, a rotating frame is rotatably mounted on the lower part of the roller, a slide rod is fixedly mounted on the bottom of the rotating frame, a sliding sleeve is sleeved on the middle part of the surface of the slide rod, and the bottom of the slide rod is fixedly connected to the top of the insert rod.

[0007] Preferably, a support platform is fixedly installed on the surface of the sliding sleeve. One end of the top of the support platform is fixedly connected to the bottom of the mounting plate through a support bar. A spring is sleeved on the upper part of the sliding rod surface. The two ends of the spring are fixedly connected to the rotating frame and the sliding sleeve, respectively. A sliding groove is opened on the top of the support platform, and the slider is slidably installed inside the sliding groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the servo motor, and when the servo motor is running, it drives the shaft to rotate inside the bushing through the coupling. When the shaft rotates, it drives the mica plate to rotate by ° through the connecting plate. Then the operator starts the drive motor to drive the transmission rod to rotate along the positioning strip. When the transmission rod rotates, it pushes the pusher to move through the cooperation of the strip groove and the transmission pin. When the pusher moves, it drives the slider to slide along the inside of the groove, which increases the stability of the pusher when it moves.

[0009] When the push bar moves, it pushes the rotating frame downwards via rollers. As the rotating frame moves downwards, it causes the slide bar to slide down inside the sliding sleeve and simultaneously press against the ceiling. This ensures the stability of the slide bar's movement while also providing it with an elastic reset effect. When the slide bar moves downwards, it causes the insertion rod to move downwards and insert into the insertion hole at the top of the connecting plate for positioning. This gives the intermediate ladle flip baffle a positioning effect, increases the accuracy of rotation and locking, avoids gaps in the cover, and has a very good performance.
