Abstract
An anti-breakdown method of electrical discharge machining is characterized in that the anti-breakdown method includes when a small hole is machined by electrical discharge, sticking low-cost isolation material to the surface of a part easy to break down electrically, and utilizing non-conductivity of the isolation material to protect the part. The isolation material includes polyvinyl chloride films, butyl rubber and natural rubber. The sticking method includes adopting a method of tap sticking directly or a method of sticking by cyanoacrylate adhesive. The anti-breakdown method has the advantages that breaking shackles of the traditional process are broken, on the prior basis of preventive protection through mutual observation and numerical control programs, passive protection is turned to be active protection, electrical protection of outer face of the solid part is completed, accordingly the technical problem in aviation high-cost electrical machining protection is provided with a reasonable solution, electrical machining scrap rate is reduced effectively, and application field is wide.
Description
Technical field
The present invention relates to the spark erosion technique field, particularly the anti-breakdown method of a kind of spark machined.
Background technology
In the spark machined, working depth can not be well controlled, and therefore when processing blind hole and similar blind hole, the breakdown phenomenon of part usually can occur, causes part to be scrapped and causes unnecessary loss.
Summary of the invention
The objective of the invention is to prevent unnecessary puncture in order to protect piece surface, the spy provides a kind of spark machined anti-breakdown method.
The invention provides the anti-breakdown method of a kind of spark machined; it is characterized in that: the anti-breakdown method of described spark machined; be specially when the spark machined aperture; to insulating materials cheaply; stick on the piece surface that is easy to generate electrical breakdown, utilize the non-conductive performance protection part of insulating materials.
Described insulating materials comprises: polyvinyl chloride film, butyl rubber, natural rubber.
The method of described stickup is: adopt adhesive tape directly to paste or with cyanoacrylate bonding agent bonding method.
In concrete operations, at workpiece shown in Figure 2, paste insulating materials at surface of the work C place, avoid puncturing this surface.
Advantage of the present invention:
The anti-breakdown method of spark machined of the present invention; broken through traditional technology constraint; can only be by manual observation originally; carry out on the basis of preventive protection on the numerical control program; it is initiatively protection that process changes passive protection, has finished the electric machining protection of entity component external surface, makes the expensive electric machining resist technology difficult problem of aviation that a rational solution arranged; effectively reduce the electric machining percent defective, application is extensive.
