Abstract

1,168,602. Making studs; drawing; extruding. J. M. PLAGEMANN, [trading as PEEWEE MASCHINEN UND APPARATEBAU WERNER PLAGEMANN]. 1 Feb., 1968 [4 Feb., 1967], No. 5199/68. Headings B3A and B3P. In a press of the kind described in Specification 921,501 for reducing the ends of stud blanks in successive steps by oppositely acting reducing dies 2 actuated by pistons 8, the right hand die performs the first step, Fig. 4 (not shown), and is thrust back by the left hand die as it performs the second step, Fig. 6 (not shown) and during this second step the right hand cylinder space 9a is connected through slide valve 12 with the pressure pipe 16 supplied by pump 15 and is also connected through pipe 22 and slide valve 23 with an exhaust pipe 17 containing an adjustable pre-loading valve 18. This provides an even retraction of the right hand die during the second stage. The slide valves 12, 23 are actuated by solenoids 19, 13 controlled by a switching device and these valves are returned by springs 14 adjustable by setting elements 24. Air vent valves 25 are provided for the cylinders.
