MACHINING UNIT AND MACHINING APPARATUS

摘要

There is provided a machining unit (10) that machines a rod-shaped member (W). The machining unit (10) includes: a first unit (23) including a first split die portion on an upper side, out of upper and lower split die portions that form a pair and include a bending channel that bends the rod-shaped member (W), and a first clamp portion on an upper side, out of upper and lower clamp portions that form a pair and hold the rod-shaped member inserted into the bending channel; a second unit (22) including a second split die portion on a lower side out of the upper and lower split die portions that form a pair and a second clamp portion on a lower side out of the upper and lower clamp portions that form a pair; a pressure unit (30) including a holding channel that holds the rod-shaped member in the bending channel from an outer circumferential side of the bending channel; and an opening-closing unit (69) that opens and closes the first unit (23), the second unit (22), and the pressure unit (30) in three different directions with respect to a setting center (C) that is a position of a center axis of the rod-shaped member (W) in a state where the rod-shaped member (W) is set the bending channel.

1. A machining unit comprising:
a first unit including a first split die portion on an upper side, out of upper and lower split die portions that form a pair and include a bending channel that bends a rod-shaped member, and a first clamp portion on an upper side, out of upper and lower clamp portions that form a pair and hold the rod-shaped member inserted into the bending channel; a second unit including a second split die portion on a lower side out of the upper and lower split die portions that form a pair and a second clamp portion on a lower side out of the upper and lower clamp portions that form a pair; a pressure unit that includes a holding channel that holds the rod-shaped member in the bending channel from an outer circumferential side of the bending channel; and an opening-closing unit that opens and closes the first unit, the second unit, and the pressure unit in three different directions relative to a setting center that is a position of a center axis of the rod-shaped member in a state where the rod-shaped member has been set in the bending channel, and includes: a first opening-closing unit that opens and closes the first unit and the second unit in a balanced manner; and a second opening-closing unit that operates in concert with the first opening and closing unit that moves the pressure away from and toward the setting center, and includes: a skirt-shaped cylindrical cam that moves up and down in concert with the first opening-closing unit; and a cam follower that moves while contacting with a circumferential surface of the skirt-shaped cylindrical cam and, in concert with the skirt-shaped cylindrical cam moving up and down and the first unit and the second unit opening and closing, moves the pressure unit relative to the bending channel so as to open and close the pressure unit.
