Description
Technical field
The present invention relates to the motor part and make field, particularly a kind of processing method of carbon brush for electric machine frame and process equipment thereof.
Background technology
To shown in Figure 4, a kind of carbon brush for electric machine frame 4 comprises the first terminal 1 and is riveted on second terminal 2 and the 3rd terminal 3 on the first terminal 1 like Fig. 1, and in the prior art, the processing method of this kind carbon brush for electric machine frame 4 roughly may further comprise the steps, with reference to Fig. 1～Fig. 4:
(1) mould that adopts a mould to go out a plurality of products stamps out the first terminal 1 with first strip, the some first preparatory riveted construction 11 and the some second preparatory riveted construction 12 that on the first terminal 1, be stamped out, and this first terminal 1 is also by curved two kinks 13 and 14 that extrude;
(2) mould that adopts a mould to go out a plurality of products stamps out second terminal 2 with second strip; The some the 3rd preparatory riveted construction 21 that on second terminal 2, is stamped out and matches with the first preparatory riveted construction 11, this second terminal 2 are also by the curved two bending ligulate shell fragments 22 that extrude;
(3) mould that adopts a mould to go out a plurality of products stamps out the 3rd terminal 3 with the 3rd strip; The some the 4th preparatory riveted construction 31, the three terminals that match with the second preparatory riveted construction 12 that on the 3rd terminal 3, are stamped out are also bent extrusion one " 7 " font shell fragment 32;
(4) with the mode of special fixture the first terminal 1 and second terminal 2 are riveted together, with the mode of special fixture the first terminal 1 and the 3rd terminal 3 are riveted together again, finally process finished product carbon brush for electric machine frame 4 through manual rivet through manual rivet.
The shortcoming of this kind processing method is: production efficiency is low, and labour intensity is big; Three kinds of terminals go out a plurality of products by a mould respectively and are stamped to form, and are difficult to guarantee the moulding of each product and the stability of angle; Three kinds of terminals all need be bent pressure, and its transformation yield is low; The spot that stays during the hand riveting is prone to the surface of oxygenated products, and defective such as the hand riveting also can cause because the location is inaccurate that riveted joint is bad, off normal, pulling-out force are not enough.
Chinese invention patent 200710030090.9 discloses a kind of production method of DC electric machine carbon brush holder; The mode of the elastic arm automatic press combination of adopting brass strip and the self-feeding of beryllium copper strip, the terminal that will be processed by the brass strip again and being processed by the beryllium copper strip is produced; The production efficiency that affair is established in this production method and production thereof is high; And terminal and elastic arm combine firmly, and quality is also secure.Yet the production method of this DC electric machine carbon brush holder and production equipment thereof can not be produced the carbon brush for electric machine frame with three terminals, and it has following defective:
