Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic-assisted mold steel processing equipment, and in particular relates to an ultrasonic-assisted mold steel ingot vacuum melting furnace. Background Technology

[0002] Ultrasonic-assisted mold steel must be able to be smelted in a vacuum melting furnace. This process involves heating metal ores, waste materials, or alloy raw materials to melt them, and then removing impurities and adjusting the composition through physical or chemical actions to obtain the desired metal or alloy.

[0003] Because the doors of conventional melting furnaces open in a fan-shaped direction to one side, and the opened door occupies a large area of ​​the aisle, this causes the problem of conventional vacuum melting furnaces blocking the aisle when the door is opened.

[0004] To address these issues, we propose an ultrasonic-assisted vacuum melting furnace for mold steel ingots. Utility Model Content

[0005] The purpose of this invention is to solve the problem of conventional vacuum melting furnaces occupying passageways after the door is opened, and to propose an ultrasonic-assisted vacuum melting furnace for mold steel ingots.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ultrasonic-assisted vacuum melting furnace for mold steel ingots includes a vacuum melting furnace. A fixed platform is fixedly connected to the lower end of the furnace. A guide frame and a guide column are fixedly connected to the front of the fixed platform. A lifting frame is slidably mounted on the upper part of the guide column. A furnace cover is slidably mounted on the lifting frame. A sprocket is rotatably mounted on the guide frame, and a chain is fitted onto the sprocket. One end of the chain is fixedly connected to the lifting frame, and the other end of the chain is fixedly connected to a weight. The weight is slidably mounted on the guide frame, and the upper end of the guide column is fixedly connected to the upper part of the guide frame. The weight acts downwards on the chain, causing the other end of the chain to act upwards on the lifting frame, which in turn acts upwards on the furnace cover, reducing the weight of the furnace cover. This pulls the furnace cover downwards, closing it to the vacuum melting furnace. A vacuum is created in the furnace, and the negative pressure tightens the furnace cover, ensuring it is closed. The lifting mechanism for opening and closing the furnace cover prevents it from obstructing the passageway and improves floor space utilization.

[0007] Preferably, a T-shaped frame is fixedly connected to the front end of the furnace cover. Pulling the T-shaped frame 6 downward and then pushing it backward causes the T-shaped frame 6 to pull the furnace cover downward, closing the furnace cover with the vacuum melting furnace. The vacuum melting furnace is then started to draw a vacuum, using atmospheric pressure to press and fix the furnace cover, facilitating manual operation of the furnace cover.

[0008] Preferably, a spherical block is fixedly connected to the lower end of the T-shaped frame. The spherical block increases the smoothness of the lower end of the T-shaped frame 6, preventing the lower end of the T-shaped frame 6 from puncturing or injuring workers.

[0009] Preferably, the guide frame includes a first frame, and a bearing seat is fixedly connected to the upper end of the first frame. The bearing seat facilitates the guidance of the chain rotation.

[0010] Preferably, the lifting frame includes a second frame, with a sliding sleeve fixedly connected to the side of the second frame, and a first guide wheel and a second guide wheel rotatably mounted inside the second frame. The first guide wheel guides the furnace cover to slide back and forth, reducing the sliding resistance of the furnace cover.

[0011] Preferably, the furnace cover includes a cover body, and a sliding rod is fixedly connected to the front end of the cover body. The sliding rod is guided to slide by the first guide wheel and the second guide wheel to reduce the sliding resistance of the furnace cover.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. The weight of the block acts downward on the chain, causing the other end of the chain to act upward on the lifting frame, which in turn acts upward on the furnace cover. This reduces the weight of the furnace cover and pulls it downward, closing it with the vacuum melting furnace. The vacuum melting furnace is then used to create a vacuum, which in turn uses negative pressure to tighten the furnace cover, ensuring it is closed on the furnace. The lifting mechanism opens and closes the furnace cover, preventing it from obstructing the passage and improving ground utilization.

[0013] 2. Pull down the T-shaped frame 6, then push the T-shaped frame 6 backward to pull the furnace cover down, so that the furnace cover is closed with the vacuum melting furnace. Start the vacuum melting furnace to draw a vacuum, and use atmospheric pressure to press and fix the furnace cover, making it easy to operate the furnace cover manually. Attached Figure Description
