Title:
PUNCH METAL MOLD
Document Type and Number:
Japanese Patent JP2016215246
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily attach-detach a punch guide and a retainer by directly elastically deforming a discontinuous annular part of an elastic body by an extension part.SOLUTION: In a resting state of not deforming a discontinuous annular part 61 in the radial direction without moving an extension part 62 of an elastic body 6, the discontinuous annular part 61 of the elastic body 6 is arranged over both of a first annular groove 1b of a punch guide 1 and a second annular groove 2b of a retainer 2, so that the punch guide 1 and the retainer 2 are immovably locked in the axial direction by sandwiching the discontinuous annular part 61. The discontinuous annular part 61 is elastically deformed in the radial direction by the movement of the extension part 62 from this locking state, and the discontinuous annular part 61 is arranged in any one of the first annular groove 1b of the punch guide 1 or the second annular groove 2b of the retainer 2, so that the discontinuous annular part 61 does not become a hindrance, and the punch guide 1 and the retainer 2 can move in the axial direction.SELECTED DRAWING: Figure 2
