Rotary die cylinder bearer attachment

摘要

This rotary die cylinder assembly (10) includes a cylinder (12) having end bearers (14) attached thereto. The cylinder includes intermediate body (16) and opposed end shafts (20). The body 16 is adapted to carry tool members (18) and the end shafts are externally threaded to receive the bearers, the bearers including an internally threaded bore (34). The cylinder body includes opposed annular end faces (30) adapted to receive associated bearer inner faces (32) in torqued metal-to-metal relation. An opening (42) is drilled between the faces (32, 33) of each of the bearers and extends into the the cylinder to receive a pin (44) to secure the bearers to the cylinder. Each opening extends into the cylinder body sufficiently so that the associated pins can be driven completely into the cylinder body end and out of engagement with the bearers. When this is done removal of the bearers and replacement thereof with new bearers, which can be pinned to the cylinders at a different location, is easily accomplished.
