PEELING MACHINE

摘要

A peeling machine is shown for the centreless turning of bars (24), having a cutter head (26) on the end face of a rotating hollow shaft (6), feed rollers (32, 33) on the entry side of the peeling machine, a front (5) and a rear guide (3) on either side of the cutter head, and a clamping carriage (12) on the exit side of the peeling machine. The rear guide is designed in the form of a tube socket and projects into the hollow shaft (6). It is fastened with its flange (11) to the machine housing (7). At its free end projecting into the hollow shaft, the rear guide has three individually spring-mounted guide elements (36, 37, 38) for the bar, which centre the latter and dampen vibrations caused by the cutting. The three guide elements are synchronised via a control ring (22) whose rotary position is flexibly pretensioned against the housing. If a guide element (36) is pressed outwards by the bar, all other guide elements (37, 38) likewise move outwards. On account of the individual spring mounting, the individual guide elements, in a delayed manner, follow an opening movement determined by the control ring. The individual springs form a first flexible abutment for each guide element (36-38)/clamping arm (39, 40). When an individual spring is pressed in, each guide element is supported on a second rigid abutment. ……
