Abstract
1303642 Making punches; jointing by stamping FOSTER WHEELER JOHN BROWN BOILERS Ltd 11 June 1970 [11 June 1969] 29587/69 Headings B3A and B3Q A punch for forming indentations around a bore, e.g. to secure a welding filler-ring 22 in a recess 24, comprises a head 12 with indenting tips 66 and a stem 14 expansible in the bore upon initial loading of the head so as to centre the stem before the tips 66 make their indentations. A divided sleeve 39 on the stem, the sections of which are surrounded by O-rings 54 and may be secured together by weld pips (48), Fig. 2 (not shown), is expanded by frustoconical surfaces 34, 36 on a core 30 of the stem as the core is depressed by initial manual load applied to the head. Increased load compresses a spring 67 between the head and core and the tips 66 engage the tube-plate 20, producing indentations when a power-hammer is applied to a shank 60 on the head.
