Description
Technical field
The utility model relates to a kind of device for electric machining, is specifically related to a kind of device for electric machining blade special-shaped slot.
Background technology
Work long hours under the high temperature conditions for making blade of aviation engine, blade processes number exhaust fenestra, after blade inner chamber passes into cold air, cold air flows out through air film hole, blade outer surface forms one deck cold air film to improve blade corrosion resistance under the high temperature conditions.Process the formation that special-shaped slot contributes to improving further cold air film at air film hole place, improve the cooling effect to blade.
As shown in accompanying drawing 4 ~ 6, blade blade and special-shaped slot figure thereof, blade profile is the curved surface of a round and smooth switching, the blade back of blade has two row's special-shaped slots, and special-shaped slot is not contour at machine direction, during existing processes special-shaped slot, electromachining equipment is utilized to carry out, utilize single electrode processing profiled groove one by one, production efficiency is lower, and the process time of an emissions groove (17) needs 30 minutes.Electrode is serious in machine direction 20 ° of angle losses simultaneously, and the uniformity of the special-shaped slot profile processed is poor.
Utility model content
The utility model provides a kind of device for electric machining blade special-shaped slot, can go out row's blade special-shaped slot, and can solve blade special-shaped slot problem not contour in the direction of the machine by row's electrode time processing.
The technical solution of the utility model is as follows:
A kind of device for electric machining blade special-shaped slot, comprise mount pad, electrode, compact heap, screw and connecting rod, described mount pad arranges row's groove, described electrode is placed in described groove, described compact heap is placed on the electrodes, described mount pad and compact heap link together by described screw, adjust described electrode to adding desired position in man-hour, tightening described screw is clamped between described compact heap and described mount pad by described electrode, described connecting rod is arranged on described mount pad, and described connecting rod is for connecting electromachining equipment.
The described device for electric machining blade special-shaped slot, its preferred version is, described number of electrodes is 17.
The described device for electric machining blade special-shaped slot, its preferred version is, the front end face of described mount pad and rear end face form 0.89 ° of angle, and the processing termination of described electrode is adjusted to the front end face of described mount pad apart from equal; To adapt to blade special-shaped slot height permutations rule in the direction of the machine.
The described device for electric machining blade special-shaped slot, its preferred version is, degree of the setting face, described electrode outlet position of described mount pad, for repairing the electrode of loss; The optimized angle in described degree face is 20 °.
The restorative procedure of sacrificial electrode is as follows: unclamp screw, export license maximum is leant out degree face about the 0.3mm of mount pad, then tightens screw and electrode is fixed, and repaiies the loss position of electrode, until flush with the degree face of mount pad with file file.The material of electrode is copper-tungsten, and the material of electrode tip holder is T8A, can not have damage when the degree face to mount pad repaiied by file file to it.
The beneficial effects of the utility model are:
1, device of the present utility model one row's electrode once can process row's blade special-shaped slot, and process time was reduced to less than 2 minutes by original 30 minutes, working (machining) efficiency is had and has increased substantially.
2, device of the present utility model can also solve blade special-shaped slot not contour problem in the direction of the machine, and carry out row's special-shaped slot of machining blade blade with this device, crudy is stablized, and the uniformity of special-shaped slot there has also been large increase.
3, device of the present utility model can also solve the repair issues of electrode after machine direction 20 ° of angle losses.
