Abstract

A wire-cutting wire passing clamp comprises a lower nozzle, a cutting wire, a lower wire guiding wheel, a wire passing clamp body, an upper wire guiding wheel, a plug pin and a torsional spring. The wire-cutting wire passing clamp is used for overcoming the defect that wire passing operation of an existing wire cut electric discharge machining workpiece is not convenient, the structure is improved, the wire passing clamp enables the cutting wire to be fixed in a groove of the lower wire guiding wheel, and the purpose of simplifying wire passing operation is achieved.

Description

A kind of line cutting threading clip

Technical field

The utility model relates to special process Electric Discharge Wire-cutting Technology field, particularly relates to a kind of line cutting threading clip.

Background technology

Wire EDM often runs into the situation of wearing line of cut, the convenience general custom of considering operation will cut the end of a thread from godet roller draw through workpiece, upper godet roller and guide the curled hair cylinder into, in the threading process, line of cut is curling relaxed state, after threading completes when guiding the curled hair cylinder into line of cut be easy to again from the seal wire race, deviate from, particularly after clamping workpiece, the line of cut that lower godet roller is deviate from is subject to narrow space, adverse effect that light is dark, and the operation that line of cut moves into lower seal wire race is very difficult.

Summary of the invention

The utility model purpose is for the defect of existing Wire-cut Electrical Discharge Machining workpiece threading inconvenient operation, carries out architecture advances, by threading clip, the position of line of cut in lower seal wire race is fixed, and realizes simplifying the purpose of threading operation.

The technical solution of the utility model is as follows:

Described a kind of line cutting threading clip, comprise lower nozzle, line of cut, lower godet roller, threading clip, upper godet roller, latch, torsion spring; The threading clip lower end forms clamp by two semi arch sheet metals, by torsion spring, be clamped on lower nozzle outside cylinder, the flat jaws in threading clip upper end, line of cut is clamping, thereby the position of line of cut in lower seal wire race fixed, the threading process only considers the workpiece hole threading and introduces the operation of seal wire race, after threading completes when guiding the curled hair cylinder into line of cut be not easy to deviate from from the seal wire race.

The beneficial effects of the utility model are: simple in structure, easy to operate, cost is low.

Fig. 1 is that the utility model is used view;

Fig. 2 is threading clip deployed condition schematic diagram;

In figure: 1, lower nozzle 2, line of cut 3, lower godet roller 4, threading clip 5, upper godet roller 6, latch 7, torsion spring.

The specific embodiment

A kind of line cutting threading clip, comprise lower nozzle, line of cut, lower godet roller, threading clip, upper godet roller, latch, torsion spring; The threading clip lower end forms clamp by two semi arch sheet metals, by torsion spring, be clamped on lower nozzle outside cylinder, the flat jaws in threading clip upper end, line of cut is clamping, thereby the position of line of cut in lower seal wire race fixed, the threading process only considers the workpiece hole threading and introduces the operation of seal wire race, after threading completes when guiding the curled hair cylinder into line of cut be not easy to deviate from from the seal wire race.

Claims

1. a line cuts threading clip, and it is characterized in that: described threading clip comprises lower nozzle, line of cut, lower godet roller, threading clip, upper godet roller, latch, torsion spring;

The threading clip lower end forms clamp by two semi arch sheet metals, by torsion spring, be clamped on lower nozzle outside cylinder, the flat jaws in threading clip upper end, line of cut is clamping, thereby the position of line of cut in lower seal wire race fixed, the threading process only considers the workpiece hole threading and introduces the operation of seal wire race, after threading completes when guiding the curled hair cylinder into line of cut be not easy to deviate from from the seal wire race.
