PROBLEM TO BE SOLVED: To provide new punch assembly configurations that increase the ease and the speed by which the modifications of the punch assembly can be made.SOLUTION: A retain-and-release member 16, which is coupled to a punch holder 15 of a punch assembly 100, engages a punch tip 18 against an end of the holder, such that a working portion of the tip extends from the end. A punch guide sidewall 10 of the assembly includes an aperture 10 aligned with an actuation interface of the retain-and-release member, when the punch holder and the engaged punch tip are slidably engaged within a guide bore 103 formed in the punch guide sidewall. The aperture provides access for applying a force to the actuation interface in order to disengage the retain-and-release member from the punch tip, while the punch holder remains within the guide bore of the assembly. Following the removal, the punch tip or another may be inserted into the guide bore and into engagement with the retain-and-release member. |
