Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum thin plate leveling, in particular to a leveling fixture with precise leveling. Background Art

[0002] A vacuum furnace is a device that performs heating in a vacuum environment. It is connected to a high vacuum pump system by a pipe in a furnace sealed by a metal cover or a quartz glass cover. It is mainly used for ceramic sintering, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing. A molybdenum plate is installed in the vacuum furnace.

[0003] The existing leveling is achieved by the upper and lower rows of rollers of the multi-roller leveling machine. However, even if the two adjacent rollers are close to each other, there is still a certain gap between their working surfaces. This results in some small ripples on the surface of the molybdenum sheet with a thickness of less than 2mm after being leveled by the multi-roller leveling machine, which affects the quality of the finished product of the tungsten-molybdenum sheet and causes a certain economic burden to the production enterprise. In view of this, a precise leveling fixture is proposed. Utility Model Content
