It is divided into two parts, each having a plurality of recesses on its inner surface, and by inserting the head of the punch into the recesses and clamping it as a stopper, the two punch holders can be separated and the punch part can be easily removed. It can be taken out.
実施例
以下、本発明の一実施例について第１図および第２図を
参照しながら説明する。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.
図に示すように、ポンチ８は刃部９と径大の頭部１ｏを
有するポンチ部１１と、このポンチ部１１を取り付ける
ポンチホルダー１２によって構成されている。前記ポン
チホルダー１２はセンターで２分割されておシ、それぞ

確保してポンチホルダー１２の凹部１３にポンチ部１１
の頭部１０を挿着して固定している。As shown in the figure, the punch 8 is composed of a punch portion 11 having a blade portion 9 and a large-diameter head portion 1o, and a punch holder 12 to which the punch portion 11 is attached. The punch holder 12 is divided into two parts at the center, each of which has a plurality of recesses 13 and a punch holding part 14 in the vertical direction on its inner surface.
0 is fitted, and the punch holding part 1
The machining dimensions 4 are important for ensuring the clearance between the blade portion 9 of the punch portion 11 and the die (not shown), and are machined so as to suppress the outer diameter of the punch portion 11. The X dimension of the tip of the punch part 11 is the hole drilling machine's die set (
This is determined by the height of the
The head 10 of is inserted and fixed.
