Abstract

1500588 Punching; strippers HOUDAILLE INDUSTRIES Inc 19 Aug 1975 [14 Feb 1975] 34436/75 Heading B3W In a sub press mechanism, the height of the rest position of a punch-guide/stripper sleeve 18 is adjustable by means of a retainer plate 32, which is rotatable, about an unthreaded portion 44 of a screw 45 securing it to a frame member 11, to position a selected one of a plurality of segments, as shown, 33-35 in overlying relationship to a bore 15 in which the sleeve is reciprocated during punching. Each portion is a different thickness from the others and extends in the path of a shoulder 17 on the sleeve 18 as a lifter spring 30 raises the punch and stripper sleeve unit after a punching stroke. A fourth segment of the plate is cut away to form a flat 37 to allow the punch and stripper sleeve unit to be removed. The plate is accurately located in each of the four positions by engagement of a spring-loaded ball 49 in a respective recess 50- 53 in the plate. The lower positions of the sleeve are used when workpieces thinner than the device is able to deal with are punched so that the sleeve acts as a guard for the operator.
