Description

Technical Field

[0001] The utility model relates to the technical field of wire-cutting machine, in particular to a positioning wire threader for wire-cutting machine. Background Art

[0002] Wire-cut EDM machines are mainly divided into two categories according to the running speed of their electrode wires: high-speed wire-cut EDM machines and low-speed wire-cut EDM machines. The electrode wire is connected to the negative pole of the pulse power supply, and the workpiece is connected to the positive pole of the pulse power supply. When the two poles are close to each other in an insulating liquid, the electric field is unevenly distributed due to the uneven microscopic surfaces of the two poles, causing the inter-electrode medium to be broken down, forming a spark discharge.

[0003] The Chinese patent with authorization announcement number CN217647654U discloses a positioning device for medium-speed wire cutting, including an electric spark wire cutting machine, a molybdenum wire and a workpiece. The front end of the electric spark wire cutting machine is fixedly connected to a workbench, and the top of the workbench is fixedly connected to a plasma water tank. It also includes a positioning mechanism for positioning the workpiece, and the workpiece is connected to the left side of the molybdenum wire through the positioning mechanism, and the workpiece is connected to the inside of the plasma water tank through the positioning mechanism; through the coordinated use of the electric spark wire cutting machine, molybdenum wire, workpiece, workbench, plasma water tank and positioning mechanism, under the action of the first positioning component, the workpiece can be automatically positioned to prevent the workpiece from offsetting during the online cutting process, which is beneficial to the cutting quality of the workpiece. Under the action of the second positioning component, the workpiece can be automatically directed and moved, and the first positioning component and the second positioning component are both automatically operated, without the need for manual operation by technical personnel in this field. Even in the plasma water tank, it can be easily operated, the use effect is good, and it is suitable for promotion.

[0004] The shortcomings of the above-mentioned existing technical solutions are: although the above-mentioned solution can automatically position the workpiece through the action of the first positioning component to prevent the workpiece from shifting during the wire cutting process, which is beneficial to the cutting quality of the workpiece; but a certain tension must be maintained during the wire cutting machine wire loading process. Without tension, it is easy to cause the wire reel to be tangled and the wire to slip out of the guide wheel, thereby seriously affecting the cutting quality. Here we provide a wire cutting machine positioning wire threader. Utility Model Content
