Claims

[Claims for Utility Model Registration] (1) One mold equipped with a die 2 in which the die base end portion 21 is fixed to one set plate 1 and the die tip end portion 22 is provided with an insertion hole 22b. A: a burring punch 8 having a punch base end portion 8a fixed to the other set plate 7 and a punch front end portion 8b insertable into the insertion hole 22b of the die front end portion 22; and this burring punch 8. A through hole 102 that slidably fits into the outer peripheral surface of the
b, the burring punch 8 is connected to the other set plate 7 so as to be slidable along the outer circumferential surface of the burring punch 8 between a close position close to the other set plate 7 and a remote position far away;
A burring mold comprising: a pad 10 which is normally held at the separated position by a pad biasing spring 12 disposed between the pad 10 and the other set plate 7; At least the punch tip end portion 8b of the burring punch 8 is configured to be detachable from the other set plate 7, and the pad 10 is provided with a through hole 101a through which the burring punch 8 can freely slide. Pad base end portion 101
and a pad distal end portion 102 which is detachably attached to the pad proximal end portion 101 and is provided with a through hole 102b that is slidably fitted to the outer peripheral surface of the punch distal end portion 8b, Said pad 1
0, the pad proximal end portion 101 is connected to the other set plate 7, and the pad biasing spring 12 is disposed between the other set plate 7 and the pad proximal end portion 101. A mold for paver rings, which is characterized by: (2) In the burring mold described in claim (1) of the utility model registration, the die 2 is connected to the die proximal end portion 21 fixed to the one set plate 1, and the die proximal end. A burring mold characterized in that the die tip portion 22 is detachably attached to a side portion 21 and is divided into the die tip side portion 22 in which the insertion hole 22b is provided.
