Description

Technical Field

[0001] This application belongs to the field of metallurgical equipment technology, and in particular relates to a one-to-two rotating vacuum furnace cover hoisting mechanism. Background Technology

[0002] With the development of the times and the progress of society, the vacuum heat treatment industry is becoming increasingly important in the metal industry. As an important piece of equipment in the vacuum heat treatment industry, the demand for vacuum furnaces is increasing, and the complexity and automation of vacuum furnace equipment are also becoming higher.

[0003] As workpieces become more complex and larger, vacuum furnaces are also developing towards larger sizes. This means the internal cavity of the vacuum furnace is becoming larger, and its overall dimensions are also increasing, resulting in a heavier furnace lid. This necessitates a specialized furnace lid mechanism to open and close the lid.

[0004] Chinese invention patent publication CN 116753728 A discloses an automatically opening vacuum furnace lid, including a vacuum furnace lid and a lifting mechanism. The lifting mechanism can open and close the vacuum furnace lid (disconnecting the furnace lid from the body) by lifting and lowering. However, in this device, one mechanism corresponds to one vacuum furnace lid, resulting in equipment redundancy and high overall plant equipment costs in factories with multiple vacuum furnaces. Utility Model Content

[0071] It should be noted that the base 1 is fixed to the bottom surface or the working platform. The arrangement of all vacuum furnaces should be within the rotation range of the furnace cover connecting arm 8.
