[0002] A related technology (publication number: CN222187765U) discloses a vacuum melting furnace for easy material handling, including a furnace body and a furnace cover. A cover groove is formed at one end of the furnace body near the furnace cover. Several fixing strips are fixedly connected to the inner wall of the cover groove near the furnace cover, and these fixing strips are arranged in a ring along the cover groove. Several connecting strips, matching the fixing strips, are fixedly connected to the outer wall of the furnace cover. These connecting strips are located on the side of the fixing strips near the cover groove and are slidably connected to the cover groove. The distance between two adjacent fixing strips is not less than the length of the connecting strip.

[0003] In the process of implementing the technical solution disclosed herein, it was found that the above technical solution has at least the following problems:

[0004] This vacuum melting furnace, designed for easy material handling, features multiple connecting strips that can slide into multiple fixed strips for positioning. Furthermore, the connecting strips can slide out from the fixed strips for disassembly. Therefore, the furnace lid can be opened or closed through the interaction between the connecting and fixed strips, facilitating loading and unloading. However, this sliding-in and sliding-out opening and closing method is prone to wear and damage between the connecting and fixed strips, thus affecting the sealing performance.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides an opening and closing device for a vacuum melting furnace cover 2, including a furnace body 1, a furnace cover 2, a lifting seat 3, a first connector 4, a first support 5, a guide shaft 6, a second support 7, and a connecting rod 8. The furnace cover 2 is detachably installed on the furnace body 1 and is used to open or close the furnace body 1 for loading and unloading materials. The lifting seat 3 is located outside the furnace body 1 and to the side of the furnace cover 2, and is used to support related components of the installation device. The first connector 4 is installed on the lifting seat 3 and is used to support the rotatable first support 5. The first support 5 is rotatably connected to the first connector 4 and installed on the outer wall of the furnace cover 2. Under the support of the first support 5 and the first connector 4, the furnace cover 2 can rotate relative to the lifting seat 3. The guide shaft 6 is slidably inserted through the lifting seat 3 along the radial direction of the furnace body 1 and can slide relative to the lifting seat 3. The second support 7 is installed on the outer wall of the furnace cover 2, along the height direction of the furnace body 1, and is located above the first support 5, used to drive the furnace cover 2 to rotate. The connecting rod 8 is rotatably mounted between one end of the second support 7 and the guide shaft 6, and can rotate relative to the second support 7 and the guide shaft 6 respectively, for transmitting driving force. Among them, the lifting seat 3 can be moved in a controlled manner to drive the furnace cover 2 to rise and fall, and the guide shaft 6 can be slid in a controlled manner to drive the furnace cover 2 to deflect.

[0039] This embodiment of the invention provides a vacuum melting furnace cover 2 opening and closing device. When the lifting seat 3 rises or falls under external force, it drives the first connector 4 and guide shaft 6 to rise or fall. Then, under the pull of the connecting rod 8, the first support 5 and the second support 7 can drive the furnace cover 2 to rise or fall. After the guide shaft 6 reciprocates under external force, under the pull or push of the connecting rod 8 and the support of the first connector 4 and the first support 5, the second support 7 can drive the furnace cover 2 to rotate clockwise and counterclockwise. Therefore, when the furnace cover 2 moves upward and rotates clockwise, it can be opened for loading and unloading. When the furnace cover 2 rotates counterclockwise and moves downward, it can be closed for melting operations. Furthermore, during the opening or closing process, there is no relative sliding between the furnace body 1 and the furnace cover 2, thus avoiding wear and damage and ensuring sealing.

The lifting plate 11 is installed at the moving end of the first cylinder 10, and moves up and down under the drive of the first cylinder 10. The support shaft 12 is installed on the top surface of the lifting plate 11 along the height direction of the furnace body 1, and is used to support the lifting seat 3. The lifting seat 3 is installed at the top of the support shaft 12.
