Abstract
An incremental forming apparatus 100 holds a workpiece 10 onto a table 110. A spindle is disposed perpendicularly above table 110. For incremental forming, an incremental forming tool 150 is mounted on the spindle, and a form portion 20 is formed on the workpiece 10. When incremental forming is completed, the tool on the spindle is replaced with a straightening tool 200, and hot air is blown out from the straightening tool 200 to anneal the edge lines 20a and 20b of the form portion 20 and to eliminate process strain.
Claims2
An incremental forming apparatus comprising:
- a table for mounting a metal workpiece;
- a workpiece clamp for fixing the metal workpiece to the table;
- a spindle disposed perpendicular to a plane formed by the table;
- and a means for relatively moving the table and the spindle;
- wherein the spindle mounts an incremental forming tool and a straightening tool in an exchangeable manner;
- and wherein the straightening tool comprises a shank portion to be inserted to the spindle, a hot-air blowout portion, an electric heater for heating an air to be supplied, a sensor for detecting temperature of the hot air at the blowout portion, and a controller for controlling the heater based on data from the sensor.
