のたわみの影響でばりが発生し易いもので、その為フー
プ材４のプレス加工時は、保守、管理、調整に手間暇が
かかり、甚だ面倒である等の問題があった。When the brazing material 3 having the flash 5 thus produced is used for manufacturing the rivet-type electrical contact described above, FIG.
As shown in b), the upper half 2 of the head of the contact material is tilted or snarled, so that a poor quality rivet type electrical contact is made,
Moreover, since the contact material must be recovered from defective products, productivity is poor and cost is high. When the brazing filler metal 3 has a large outer diameter and a thin plate thickness, the hoop filler 4
Since burrs are easily generated due to the bending of the hoop material 4, there is a problem that maintenance, management, and adjustment are troublesome during press working of the hoop material 4, which is very troublesome.
