Claims (4)
- 鉄心材料から外形打ち抜きパンチと外形打ち抜きダイで製品外形を打ち抜く外形打ち抜き行程において、外形打ち抜きパンチが製品外形の打ち抜き加工を開始する直前に、押さえ穴打ち抜きパンチと押さえ穴打ち抜きダイで製品外形の外側に押さえ穴の打ち抜き加工を開始し、押さえ穴打ち抜きパンチが押さえ穴又は打ち抜き加工中の押さえ穴に挿入されて鉄心材料を係止保持した状態で製品外形を打ち抜くことを特徴とするモータ鉄心の外形打ち抜き方法。
- 前記鉄心材料は、製品外形から等距離で等間隔の位置を少なくとも3個所以上で、押さえ穴打ち抜きパンチによって係止保持される請求項1に記載したモータ鉄心の外形打ち抜き方法。
- 鉄心材料から製品外形を打ち抜く外形打ち抜きパンチと外形打ち抜きダイと、製品外形の外側に押さえ穴打抜きダイと協働して押さえ穴を打ち抜くと共に、押さえ穴に挿入した状態で鉄心材料を係止保持する押さえ穴打ち抜きパンチを備え、外形打ち抜きパンチは先端を押さえ穴打抜きパンチの先端より所定長さ分だけ後退した位置に設定することを特徴とするモータ鉄心の製造用金型装置。
- 前記押さえ穴打ち抜きパンチは、外形打ち抜きパンチから等距離で等間隔の位置に、少なくとも3個所以上設けた請求項3に記載したモータ鉄心の製造用金型装置。
