Description

A turntable assembly that avoids the overlapping of molybdenum wires

technical field

The utility model relates to the technical field of molybdenum wire production, in particular to a turntable assembly for avoiding the overlapping of molybdenum wires.

Background technique

Molybdenum wire is usually processed into a wire-like structure from a molybdenum raw material rod by a combination of hot and cold drawing. Molybdenum wire is a consumable of wire cutting processing equipment. The molybdenum wire on the wire cutting processing equipment moves continuously with a high-voltage electric field to cut the workpiece, and the cutting precision is relatively high.

In the production process of molybdenum wire, it is necessary to rewind and unwind many times. During the winding process, the molybdenum wire is usually wound directly on the turntable. Since there is no guiding device on the turntable, the molybdenum wires overlap each other when they are wound, and it is difficult to control the rotation speed of the turntable, which makes the traction speed change greatly and the tension is not uniform, which affects the The quality of the reel and subsequent production.
