Title:
STRAIGHTENER FOR SHAFT MEMBER
Document Type and Number:
WIPO Patent Application WO/2007/052361
Kind Code:
A1
Abstract:
A straightener enabling the easy adjustment of correcting rolls and a reduction
in setup time and cycle time. The fixed side correcting roll (11) and a movable
side correcting roll (13) are disposed parallel with each other in a device body
(10). The movable side correcting roll (13) is formed to be radially moved close
to and apart from the fixed side correcting roll (11). A taper roller (39) for correcting
the bevel part (27) of an engine valve is vertically movably disposed in a mobile
body (12) in which the movable side correcting roll (13) is disposed. Guide members
(25) holding the engine valve are disposed on a rotating member (24) rotatably
disposed on the fixed side straightening roll (11). Thus, the shaft part of the
engine valve held on the guide member (25) can be straightened by passing it through
a clearance between these both correcting rolls (11) and (13). In this case, the
bevel part of the engine valve can be corrected by the taper roller (39).
