Abstract

The utility model provides a take wire -electrode cutting molybdenum filament wheel frame of guide ring, include, support body and guide holder, fixed mounting has a pair of guide holder on the support body, and a swing joint pivot between the wheel stand has the guide pulley of taking the recess in, also have two guide rings, the inboard and support body fixed connection of guide ring, the guide ring outside is the conical surface to to the guide pulley extension, cover the clearance between guide pulley and the wheel stand, the silk thread can fall into in the guide pulley recess along the conical surface outside the guide ring. The utility model has the advantages of: threading is convenient, in any case can not wear in the guide pulley outside, reduces the loss, raises the efficiency.

Description

A kind of Linear cut molybdenum filament guide wheel frame of tape guide ring

Technical field

The utility model relates to a kind of Linear cut molybdenum filament guide wheel frame.

Background technology

Existing general Wire EDM wheel stand does not have a guider, need carefully to check, otherwise molybdenum filament being easily through outside guide wheel, causing unnecessary loss when wearing molybdenum filament.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides a kind of Linear cut molybdenum filament guide wheel frame of tape guide ring, comprises, support body and guide holder, support body is installed with a pair guide holder, between wheel stand, is flexibly connected a rotating shaft, rotating shaft has the guide wheel of a band groove, also have two guide rings, be fixedly connected with support body inside guide ring, be the conical surface outside guide ring, and extend to guide wheel, cover the gap between guide wheel and wheel stand, silk thread can fall into along the conical surface outside guide ring in guide wheel groove.

Described guide ring is at least 1/4 annulus.

The utility model has the advantage of: wear silk convenient, in no case can be through outside guide wheel, reduce the loss, raise the efficiency.

Detailed description of the invention

The utility model provides a kind of Linear cut molybdenum filament guide wheel frame of tape guide ring, comprise, support body 7 and guide holder 2, support body 7 is installed with a pair guide holder 2, a rotating shaft 3 is flexibly connected between wheel stand 2, rotating shaft 3 there is the guide wheel 4 of a band groove 5, also have two guide rings 1, be fixedly connected with support body 7 inside guide ring 1, it is the conical surface outside guide ring 1, and extend to guide wheel 4, cover the gap 6 between guide wheel 4 and wheel stand 2, silk thread can fall into along the conical surface outside guide ring 2 in guide wheel 4 groove 5.

Described guide ring 1 is at least 1/4 annulus.

As shown in Figure 3, two guide ring 1(or some/guide ring 1) be installed on inside support body 7 respectively, leave a little gap between two guide rings 1, guarantee not interfere guide wheel to rotate, and guide wheel 4 groove 5 is just in time aimed in gap.External diameter is taper surface, when molybdenum filament falls within taper surface, forces molybdenum filament to slide in guide wheel groove.

Claims (2)

1. a Linear cut molybdenum filament guide wheel frame for tape guide ring, comprises, support body and guide holder, support body is installed with a pair guide holder, be flexibly connected a rotating shaft between wheel stand, rotating shaft have the guide wheel of a band groove, it is characterized in that, also have two guide rings, be fixedly connected with support body inside guide ring, be the conical surface outside guide ring, and extend to guide wheel, cover the gap between guide wheel and wheel stand, silk thread can fall into along the conical surface outside guide ring in guide wheel groove.

2., by the Linear cut molybdenum filament guide wheel frame of a kind of tape guide ring according to claim 1, it is characterized in that, described guide ring is at least 1/4 annulus.
