Patent attributes
A spring manufacturing apparatus comprises a tool support (30, 40, 50) which supports a tool in a way that the tool can be slid toward the spring forming space. A plurality of the tool supports can be arranged in a radial pattern from the spring forming space on the forming table. The apparatus also comprises a driving force transmission unit (70), attached to the tool support on the forming table, which transmits driving force to the tool support for sliding the tool. The tool support includes first and second tool supports for driving a tool by different driving methods. The first tool support (30) comprises a first driving mechanism (32) that transmits driving force of a common driving axis to the tool. The second tool support (40) comprises a second driving mechanism (41) that transmits driving force of the driving axis to the tool.
