Abstract:
1. A roll grooving apparatus for circularly grooving a tubular workpiece, the apparatus comprising: a backup roller fixedly engaged with a primary housing of the apparatus; a grooving roller fixedly engaged with a secondary housing, the secondary housing engaged with the primary housing for relative linear motion therewith, said linear motion causing a change in spacing between the backup roller and the grooving roller; a linear actuator engaged with the primary housing and enabled and positioned for driving the secondary housing with said linear motion; a support bar engaged with the primary housing through a means for adjustment thereby enabling selective adjustment of a spacing between the backup roller and the support bar; and the backup roller engaged with a driver for rotation of the backup roller; whereby, the backup roller and the grooving roller compressively engage the tubular workpiece with force applied by the linear actuator, the backup roller driven in rotational motion by the driver, thereby imparting a circular groove in the tubular workpiece.
