Embodiment:

Present embodiment is the preferred embodiment for the present invention, and other all its principle is identical with present embodiment or approximate with basic implementation, all within protection range of the present invention.

Realization process of the present invention is as follows:

A), at the reed back-end location in advance towards small square hole;

B), the precompressed fault trough that is used for reed and technology limit in the punching press of small square hole tail end;

B-1), side edge excision technology limit;

C), Sheet Metal Forming Technology hole on described reed technology limit;

D), at reed front position pre-punched hole;

E), the reed front position is ironed;

F), once more in the punching of reed front position, the expansion shape size of reed front end is put in place;

I), with two fork perks;

J), single tine is led machine-shaping;

K), two forks are set back, and with bayonet socket machine-shaping;

K-1), after the bayonet socket machine-shaping, proofread and correct the symmetry at bayonet socket center;

L-1), after lead leg is shaped, remove lead leg because the burr that punching press causes.

M), punching press flake on the reed lead leg;

N), proofread and correct the linearity of reed lead leg;

O), proofread and correct curling of reed technology limit;

O-1), the arc on correction process limit;

O-2), the correction process limit distortion.

The present invention is the machining manufacture of female reed of European connector, wherein, reed adopts the coiled strip copper strips to process by multistation carbide alloy progressive die high speed stamping, please referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, the Working position of each procedure of processing shown in the accompanying drawing 1 (operation), and processing back shape, for clearer each step of expressing of energy, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 provide the partial enlarged drawing of accompanying drawing 1.

Steps A is prepared for step B precompressed fault trough at reed back-end location pre-punched hole 1, and it is mobile to allow material have living space; 1 tail end punching press is used to separate the precompressed fault trough 2 on reed and technology limit to step B in the hole, so that reed in use, easily along precompressed fault trough 2 separately; Step B-1 carries out punching press with side edge with technology limit 3, eliminates the arc distortion that material is caused by internal stress, for the precision stamping of follow-up work step is prepared; The circular fabrication hole 4 of step C punching press on described reed technology limit; Step D prepares for follow-up attenuation operation at reed front position pre-punched hole 5, and it is mobile to allow material have living space; Step e is ironed with reed front position 6, satisfies the thickness requirement of reed single tine and two forks; Step F puts the processing of reed front end development size in place once more in the punching press of reed front end; Step G is in the two fork guiding 8 of reed front position punch process, with 8 machine-shapings of leading of two forks; Step H carries out tearing notch 9 in reed front end centre position, and two forks are separated with single tine; Step I becomes the two fork guiding 10 of perk with 8 perks of leading of two forks, so that the processing of single tine guiding 11; Step J is the 11 typing punch process moulding of single tine guiding, makes single tine 11 tops of leading form circular prerotation vane, finishes the processing of single tine guiding 11; Step K sets back two forks 8, and with bayonet socket 12 machine-shapings; After 12 machine-shapings of step K-1 bayonet socket, proofread and correct the symmetry 13 of bayonet socket 12; Step L makes the lead leg moulding of reed at reed back-end location punching press lead leg 14; Step L-1 removes the lead leg both sides because the burr 15 that punching press causes makes the smooth no burr in lead leg both sides after lead leg is shaped; Step M is punching press fish eyelet 16 on the reed lead leg; Step N proofreaies and correct the linearity 17 of reed lead leg, makes it reach predetermined requirement; Curling of step O correction process limit; The arc on step O-1 correction process limit; The distortion on step O-2 correction process limit.

Please referring to accompanying drawing 5; among the present invention; each operation that realizes mould of the present invention adopts arrangement shaping continuously on template 41, is followed successively by in advance towards small square hole operation 21; precompressed fault trough operation 22; side edge operation 23; towards fabrication hole operation 24; in advance towards irregularly-shaped hole operation 25; attenuation operation 26; towards irregularly-shaped hole operation 27; two fork guiding molding procedure 28; tearing notch operation 29; two fork guiding perk operations 30; single tine guiding forming process 31; bayonet socket forming process 32; bayonet socket symmetry correcting process 33; towards lead leg operation 34; lead leg deburring operation 35; flake stamping procedure 36; linearity correcting process 37; school volume operation 38; school arc operation 39; detrwisting operation 40.
