Precision forming tool for tubes and rods - has radial hammers displaced precise distance by cam units with central drive controlled by electronic programmable controller

摘要

The forming tool is used for processing tubes (2) that have to be produced with thin walls and highly accurate sizes. The tube is moved axially through the tool while a number of radially located forming hammers (3) are moved radially against the outer surface. The hammers are located within a central guide block (17) and have an outer surface (11) that is cam shaped. The radial reciprocating movement of the hammers is produced by a number of cylindrical cam followers (9) each supported on a spindle (25). The hammers and followers are held in contact by springs (7). The rollers and block are rotated by a motor (30) via a gear transmission, under the control of a microprocessor (31) based unit operating as a programmable controller. ADVANTAGE - Precise control of forming stroke.
