Description
Technical field
It is specifically a kind of to be used for spark-erosion sinking the present invention relates to a kind of processing method of technical field
The processing method of processing profiled hole type parts.
Background technique
EDM forming technology is capable of processing high-melting-point, high rigidity, high intensity, high-purity, a variety of materials of high tenacity
The energy density of pulsed discharge is high, easy to process that the special material that work can not process is difficult to common machining process
It with the workpiece of complicated shape, is not influenced by material hardness, heat-treated situation does not influence.The duration of pulsed discharge is extremely short,
The heat conduction range of scatter generated when electric discharge is small, and the material range that is influenced by heat is small.When processing, tool-electrode and workpiece material are not
Contact, macroscopical active force is minimum between the two.Tool-electrode material is not required to harder than workpiece material.It is widely used in aerospace neck
The processing of domain difficult-to-machine material.
In the sinking EDM of difficult-to-machine material, especially for the more irregularly-shaped hole part of hole number, at present
Using single electrode hole machined one by one, under normal circumstances, each hole of each part will first carry out roughing respectively, and roughing is complete
It is finished again, whole process expends longer time, and production efficiency is low.
To improve processing efficiency, when roughing, often uses high current to process, and export license is larger, when using same size
It when electrode carries out Roughing and fine machining, can not guarantee simultaneously rough machined efficiently accurate with finishing size, generally require to finish
It is separated with finishing electrode.It, need to be by operating after roughing when using single electrode, hole carries out roughing and finishing respectively one by one
Work is replaced machined electrode manually and is finished, and will cause resetting error to a certain extent at this time, affects part matter
Amount, and efficiency is very low.
Meanwhile irregularly-shaped hole machined electrode, due in irregular shape, the processing of electrode positions and the detection of installation site
It is more difficult.
Summary of the invention
The purpose of the present invention is successively carry out causing between roughing and finishing because of replacement electrode for irregularly-shaped hole
Resetting error the problem of and coarse-fine processing separately lead to process time too long problem, design a kind of irregularly-shaped hole electricity
Spark integrated coarse and fine processing method reduces resetting error, and then improve part quality to improve production efficiency.
In order to solve the above-mentioned technical problem, one technical scheme adopted by the invention is that:
A kind of abnormity hole electric spark integration machined electrode characterized by comprising electrode gripping section 1, benchmark section 2, electrode essence

The profiled holes are diamond hole.
The electrode roughing section 4 is 0.1-0.3mm smaller than electrode finishing section 3.
On the other hand, a kind of irregularly-shaped hole electric discharge machining method, step are as follows:
Electrode gripping section 1 is mounted on spark-erosion machine tool main shaft chuck, centering electrode position is positioned by 3 position of benchmark section;
The roughing of irregularly-shaped hole is carried out with electrode roughing section 4;
The finishing of irregularly-shaped hole is carried out with electrode finishing section 3.
The electrode roughing section 4 carries out using high current, long pulse width when roughing, carries out going for big surplus
It removes.
The electrode finishing section 3 is finished when back segment is finished using low current, short pulse width.
Electrode roughing section 4 of the invention carries out using high current, long pulse width when roughing, carries out going for big surplus
It removes, speed is fast, high-efficient;Electrode finishing section 3 cooperates short inter-train pause when back segment is finished again using low current
With pulse width, irregularly-shaped hole is machined to satisfactory size requirement, two process segments cooperate, and improve precision.
Electrode gripping section 1 is coupled with spark-erosion machine tool main shaft chuck, processing and detection base of the benchmark section 2 for electrode
The detection benchmark of standard and electrical spark working working hour electrode installation site realizes the accurate of electrode machining and electrode installation site
Detection.
Machined electrode clamped one time of the invention can carry out the roughing and finishing of multiple irregularly-shaped holes, effectively
Resetting error is avoided, total elapsed time is shortened, improves production efficiency.And then improve product quality.
Compared with prior art, the present invention the beneficial effect generated is:
1) a kind of special-shaped hole electric spark integrated coarse and fine processing method has been invented, can have been fitted in EDM Sinking Equipment
With, especially for the part for including Complex Different Shape hole, total elapsed time is substantially reduced, improves processing efficiency, promotion
Product quality.
2) the invention patent uses unique projective table type structure electrode, and front and back section carries out coarse-fine processing respectively, and cooperation is not
Same discharge parameter, shortens the rough machined time, improves finishing precision.A piece electrode clamped one time can be multiple to realizing
The roughing and finishing in hole reduce resetting error caused by replacement electrode.
3) the benchmark section of the invention patent setting, convenient for electrode machining, detection and the transmitting of electrical spark working working hour benchmark
It is detected with installation site, ensure that the accuracy of irregularly-shaped hole Working position.
