Abstract
【解決手段】打錠成形用の杵の先端部を切断除去し、残った胴体部Bの先端中心部に、開口部1の径が胴体部Bの径の40−55%で、深さが開口部1の径の1.6倍−4倍である円筒状凹部2を設け、先端に成形面4を有する棒状体5の後端に鍔状の台座6を介して円柱状凸部3が設けられた先端部A’を、前記円柱状凸部3を前記胴体部Bの円筒状凹34に嵌合して一体化し、新たな杵とする。
【選択図】図1
Description
図1の例は下杵に関するものであるが、先端部Aが磨耗又は破損した杵Xを、先端部Aと胴体部Bに切断分離し[図1(1)参照]、先端部Aは廃棄処分し、胴体部Bを、図1(2)に示すように、その先端中央部に、開口部1の径が胴体部の径の50%で、深さが前記開口部1の径の2.2倍である、円筒状凹部2を設けた。この例では、円筒状凹部2の底面を逆円錐状として、中心部が深くなるようにし、また、胴体部Bの肩部周辺は曲面をなすように面取りしている。
