All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the composite fan blade and the tool for processing the inner surface of the metal wrapping edge comprise a metal wrapping edge 105 and a clamp body 15, wherein the cross section of the metal wrapping edge 105 is U-shaped, one side of the metal wrapping edge 105 close to the central point is a processing surface, one side of the metal wrapping edge 105 far away from the central point is an electrochemical blank processed surface 2, a strip-shaped groove attached to the metal wrapping edge 105 is formed in the clamp body 15, and the inner wall of the strip-shaped groove is a positioning surface 16.
The clamp air holes 12 are formed in the two sides of the clamp body 15.
Two support pins 10 and 14 are respectively mounted at two ends of the clamp body 15.
Three groups of rectangular grooves are formed in the inner walls of the two sides of the strip-shaped groove.
The processing method of the metal wrapping inner surface processing tool comprises the following steps:
the first step is as follows: clamping, namely clamping the electrochemical machining blank 100 on the clamp body 15;
secondly, rough machining, semi-finish machining and finish machining are carried out on the electrochemical machining blank 100 clamped on the clamp body 15, and a blank 103 to be roughened is obtained;
the step of obtaining the blank to be textured 103 is as follows:
s1: respectively connecting the first process boss 4 and the nesting electrode 9 to the positive electrode and the negative electrode of the electrochemical nesting processing power supply 200;
s2: the position of the jacking electrode 9, which is cut into 300 from jacking processing, is close to the end face of the process boss II 5, and meanwhile, the jacking processing electrolyte interface 8 flows out of the jacking electrode 9, so that electrochemical anode dissolution occurs on the end face of the process boss II 5, the shape of the erosion is similar to that of the end face of the jacking electrode 9, when the jacking electrode 9 moves to the jacking processing cut-out 301 position along a jacking motion track 11 at an electrochemical processing feeding speed (generally 1-3 mm/min), the jacking core body 101 is gradually processed, in order to prevent the jacking core body 101 from sagging at the cut-in position due to weight deformation, when the motion position of the jacking electrode 9 exceeds the position of the process support hole II 3, the support pin II 10 is inserted and passes through the process support hole II 3;
s3, when the nesting electrode 9 moves to a position beyond the first process support hole 1, inserting the first support pin 14, continuously moving the nesting electrode 9 to a nesting machining cutting-out 301 position and further cutting out from the first process boss 4, separating the complete nesting core body 101 from the electrochemical machining blank 100, taking out the first support pin 14 and the second support pin 10, removing the nesting core body 101, completing the electrochemical nesting machining, and generating an electrochemical grinding blank 102;
s4, connecting the anode of an electrochemical grinding power supply 201 with the electrochemical grinding blank 102, connecting the cathode with the finger electrode 19, and enabling working liquid to flow out of the finger electrode liquid outlet 20 at a certain flow rate and pressure all the time when the rotating finger electrode 19 is in a working state, wherein when the electrochemical grinding power supply 201 loads the anode and the cathode, and when the inner surface of the electrochemical grinding blank 102 is close to the finger electrode, electrochemical corrosion or a small amount of spark discharge can be generated, and corrosion-removed substance particles are generated, and the working liquid flushed out of the finger electrode liquid outlet 20 can flush away the corrosion-removed substance from a corrosion or discharge area and can play a cooling role on the electrode and a workpiece. The inner surface of one side of the electrochemical grinding blank 102 is progressively finished as the finger electrode 19 is advanced along electrode path one 22 to the electrochemical grinding plunge 501 position, and the other side of the metal surface is finished as the electrochemical grinding plunge 501 position is advanced along electrode path one 23 to the electrochemical grinding plunge 502 position. The blank 103 to be roughened is thus produced, the inner surface bottom groove 24 being completed by an electrochemical forming process or by a conventional milling process. The first electrode motion track 22 and the second electrode motion track 23 may be formed by respectively machining two side surfaces in a reciprocating manner, or by continuously machining two side surfaces in a zigzag or spiral manner.
The third step: the finished part metal hem 105 is prepared by electrochemical corrosion processing 600.

the positive electrode of an electrochemical corrosion parameter power supply 202 is connected with a process boss II 5 of the blank 103 to be roughened, the negative electrode is connected with a tool electrode 25 with a simple shape, when the power supply is electrified, the tool electrode 25 traverses two side surfaces of the blank 103 to be roughened according to a certain movement track, and meanwhile, flowing electrochemical solution 26 is filled between the tool electrode 25 and the two side surfaces of the blank 103 to be roughened, so that the surface of the blank 103 to be roughened generates pit characteristic features under the action of electrochemical corrosion, an electrochemical corrosion transition piece 104 is finally generated, and the process boss I4 and the process boss II 5 on the two sides of the electrochemical corrosion transition piece 104 are cut off by linear cutting, so as to obtain a finished part metal edge covering 105.
Before processing, a layer of mask is covered on the surface to be corroded of the blank 103 to be roughened, and the non-processing surface is protected from corrosion, the mask has certain hole characteristics, so that the covered surface of the blank 103 to be roughened corresponds to the lower surfaces of the hole characteristics, and the blank is exposed in the electrochemical solution 26 in the electrochemical corrosion processing 600 process. When the power supply is electrified and the blank 103 to be roughened covered with the mask, the tool electrode 25 and the clamp body 15 are immersed into the flowing electrochemical solution 26 together, the surface of the blank 103 to be roughened generates a pit characteristic morphology, and finally the electrochemical corrosion transition piece 104 is generated, and the process bosses I4 and the process bosses II 5 on the two sides of the electrochemical corrosion transition piece 104 are cut off by wire cutting to obtain the finished part metal edge covering 105.
