Molybdenum wire winding device and winding equipment

Abstract

The invention provides a molybdenum wire winding device and winding equipment, and relates to the technical field of wire cutting. The molybdenum wire winding auxiliary device comprises a molybdenum wire disc and a damping unit. The molybdenum wire disc is connected with one end of a molybdenum wire. The molybdenum wire can be wound on the molybdenum wire disc. The other end of the molybdenum wireis configured to be connected with a molybdenum wire winding unit. The damping unit is disposed on the molybdenum wire disc. The damping unit is configured to control the rotating speed of the molybdenum wire disc so as to control the tension degree of the molybdenum wire between the winding unit and the molybdenum wire disc. The damping unit can provide stable damping force, so that the tensileforce of wire winding can be stable, and the wire cannot be too tight or too loose; and moreover, by means of the molybdenum wire winding device, it can be avoided that wires are overlapped or brokendue to shaking in manual operation during wire winding. In addition, the wire winding and wire tightening can be completed at a time, and there is no need to tightening the wire after winding the wire. Thus, the molybdenum wire winding device can improve the molybdenum wire winding efficiency and better facilitates operation.

Description

Technical field [0001] The invention relates to the technical field of wire cutting, in particular to a molybdenum wire winding auxiliary device and winding equipment. Background technique [0002] Wire cutting is wire EDM, which is a processing method in which the molybdenum wire is continuously discharged between the workpiece and the workpiece is eroded under the action of the electric spark. Therefore, the wire cutting molybdenum wire has a short service life and needs to be replaced frequently. [0003] In the prior art, when the molybdenum wire needs to be replaced, the thread end of the molybdenum wire is fixed to one end of the thread roller with a screw. Then the molybdenum wire is wound on the rolling drum by the rotation of the motor; at the same time, the rolling drum will move along its own axis (screw nut pair), so that the molybdenum wire can be wound on the rolling drum without overlapping. After winding the wire, fix the other end of the molybdenum wire with a scr...

Problems solved by technology

[0004] However, in the above two-step operation process, if the operator's arm shakes slightly, there will be overlapping wires, so that the wires will be rewound or even broken.

In addition, this operation also has high requirements on the strength of the operator. If the force is small, the winding wire will be too loose; if the force is too high, the wire will break
