Shape is almost synchronous to be carried out, and amount of interference and fit clearance are relatively uniform；Thickness of interlayer structure also can guarantee preferable riveting quality,
The joint fatigue service life is far above common riveted joint.Electromagnetic riveting is mostly once-forming, and opposite hammer riveting noise pollution is low, while
The flow harden phenomenon of material when avoiding multiple riveting.The forming that can be used for difficult moulding material rivet, pier nose when avoiding hammering riveting into shape
There is the phenomenon that failure by shear in place.
Electromagnetism self-piercing riveting combines electromagnetic riveting and traditional self-piercing riveting, it without beating in advance compared with electromagnetic riveting
Hole is saved greatly production cost ensureing connector to have except certain reliable intensity；Compared with traditional self-piercing riveting it
It is loaded using electromagnetic force, the rivet force of top load high-speed can also be provided while easily controllable realization automation, study table
Bright its has better mechanical property compared with traditional self-piercing riveting.Electromagnetism self-piercing riveting discharge coil is to provide power for punch
Critical piece.Therefore, loop construction design directly concerning to electromagnetic rivetter capacity usage ratio and itself use the longevity
Life.Frequent more emat coil can both cause technique unstable, can also increase cost input, influence production industrial production process.Coil system
Make includes mainly frame design, conducting wire winding and pigtail splice connection.Currently, be bolted mostly around the coil that makes with
Coil rack.Coil can have certain impact power when due to riveting, be easy to loosen damage.In addition, coil lead usually uses
Flat type copper wire mode is bent, or is drawn using bolt presses joint style, copper wire bending insulation easy damaged fractures frequent occurrence,
Bolt looseness is it occur frequently that connector " sparking " burns copper wire.Specifically, as patent application CN105761900A coil leads are drawn
Mode has multiple right angle to bend using 45 degree of folds, and copper wire easily occurs damage and even fractures；As traditional electromagnetic riveting swashs
The manufacturing technology coil lead connector for encouraging coil is crimped using bolt, and connector easily occurs " sparking " and burns copper wire.Therefore, electromagnetism from
Sleeving and riveting wiring circle must possess enough mechanical strengths and good insulation performance, it is also contemplated that pigtail splice connectivity problem.
Discharge coil optimization is to promote and apply electromagnetism self-punching riveting technology to solve the problems, such as.
