きるようにしてテーブル４に連結しである。The machine frame 5 has a bent portion 6 formed by the pressing die 2 and the receiving die 3.
Two racks 7a, 7b located at different distances from each other
The upper end of the rack 7a, which is closer to the bending part 6, is pivoted to the table 4, and the upper end of the rack 7a, which is closer to the bending part 6, is pivoted to the table 4.
The upper end of the rack 7a is connected to the table 4 so that it can move only toward the pivot point a of the rack 7a.
また一方のラック７ａは機枠５に設けたシリンダ装置９
に連結しである。Moreover, one rack 7a is a cylinder device 9 provided in the machine frame 5.
It is connected to.
上記両ラック７ａ、７ｂにはピニオン１０ａ、１０ｂが
噛合しており、この両ピニオン１０ａ、１０ｂの軸１１
ａ、 １１ ｂには互いに噛合するギヤ１２ａ、１２
ｂか′固着しである。Pinions 10a and 10b are engaged with both the racks 7a and 7b, and shafts 11 of these pinions 10a and 10b are engaged with each other.
Gears 12a and 12 that mesh with each other are a and 11b.
b or ' is stuck.
そしてこのギヤ１２ａ、１２ｂ、ピニオン１０ ａ、
１０ ｂの歯数比は、折り曲げ部６に近い方のラック７
ａのストロークに対して遠い方のラック７ｂのストロー
クが大きくなるように増速する関係にとられている。And these gears 12a, 12b, pinion 10a,
The tooth ratio of 10 b is the rack 7 that is closer to the bending part 6.
The relationship is such that the stroke of the rack 7b that is farther from the rack 7b increases in speed relative to the stroke of the rack 7b.
そしてこの増速比は、折り曲げ部６からテーブル４と両
ラック７ａ、７ｂの連結点１３．１４との長さＡ、
Ｂの比（Ｂ／Ａ）と一致させである。This speed increase ratio is determined by the length A from the bending part 6 to the connection point 13.14 between the table 4 and both racks 7a and 7b;
This is to match the ratio of B (B/A).
上記構成において、シリンダ装置９を伸縮動することに
より、テーブル４は折り曲げ部６を中心にして回転運動
を行なう。In the above configuration, by extending and contracting the cylinder device 9, the table 4 rotates around the bending portion 6.
従って、上記シリンダ装置９の伸縮動をプレスブレーキ
１の動作と同期して行なうことにより、テーブル４は折
り曲げられる金属板に沿って回動し、この金属板を支持
する。Therefore, by extending and contracting the cylinder device 9 in synchronization with the operation of the press brake 1, the table 4 rotates along the metal plate to be bent and supports this metal plate.
本考案は以上のようになり、機枠５に複数個のラック７
ａ、７ｂを上下方向に摺動自在に、かつプレスブレーキ
１の折り曲げ部６に対する距離をそれぞれ異ならせて設
け、この各ラック７ａ、７ｂの上端部をテーブル４に連
結してテーブル４を支持し、また各ラック７ａ、７ｂに
噛合するピニオン１０ａ、１０ｂを各ラック７ａ、７ｂ
が゛それぞれ同一方向に移動するように連動連結すると
共に、その各ピニオン相互の回転比を、各ラック７ａ。The present invention is as described above, and a plurality of racks 7 are mounted on the machine frame 5.
The racks 7a and 7b are provided vertically slidably and at different distances from the bent portion 6 of the press brake 1, and the upper end of each rack 7a, 7b is connected to the table 4 to support the table 4. , and pinions 10a and 10b that mesh with each rack 7a and 7b are connected to each rack 7a and 7b.
The racks 7a are interlocked so that they move in the same direction, and the rotation ratios of the respective pinions are adjusted.
７ｂのテーブル４に対する連結点１３，１４と折り曲げ
