When the first rack gear (30) stretches out sliding outwardly, one end of first finger (46) and the first driving lever (48) is drivingly connected So that the first driving lever (48) rotates, the other end of the first driving lever (48) pushes the second finger (47) so that the first limited block (40) is remote From the first curved mandrel (24) of rotation.

9. a kind of bender described in accordance with the claim 1, which is characterized in that described second, which revolves bender structure, includes

The second support plate (49) being fixed on rack (1)；

The second shaft (50) being rotatably connected in the second support plate (49), second shaft (50) is horizontally disposed, The second perforation (51) and the second mounting groove (82) are equipped at the axle center of second shaft (50)；

The second curved driving mechanism of rotation that the second shaft (50) rotate is driven, the curved driving mechanism of second rotation is fixed on rack (1) On；

Movable the second curved mandrel (52) of rotation being connected in the second perforation (51), described second revolves curved mandrel (52) and second turn Axis (50) is coaxial；

The curved mandrel (52) of the second rotation of driving pushes so that the end of the second curved mandrel (52) of rotation protrudes from the of the second shaft (50) Two press mechanisms (53), after the second curved mandrel (52) of rotation pushes, the side wall of the end of the second curved mandrel (52) of rotation and bar (2) Side wall abuts, and the second press mechanism (53) is fixed on rack (1)；

It is fixed on second rotation curved boom (54) of the second shaft (50) end；

It is fixed on the second rotation curved boom (54) and makes the second of bar (2) bending to revolve cambered axle with the second rotation curved boom (54) rotation and hold (55)；

When bender finishes the second back-moving spring (56) that the curved mandrel (52) of dynamic second rotation of rear-guard resets, described second resets bullet Spring (56) is set in the second mounting groove (82), and the second back-moving spring (56) is set on the curved mandrel of the second rotation (52), described One end of second back-moving spring (56) is abutted with the bottom of the second mounting groove (82), the other end of the second back-moving spring (56) It is abutted with the upper end of the second curved mandrel (52) of rotation；

One end of the separate bar of the curved mandrel of the first rotation (24) is acted in bending work to keep the curved mandrel of the second rotation (52) It is detached from the second limit assembly of the curved mandrel of the second rotation (52), the second limit group after hours in pressed status, bending Part is fixed on rack (1).

10. a kind of bender according to claim 9, which is characterized in that described second, which revolves curved driving mechanism, includes

The third driving unit (57) being fixed on rack (1)；

The second rack gear (58) being slidably connected on the second support plate (49), second rack gear (58) and third driving unit (57) driving end connection；

It is fixed on the second gear (59) of the second shaft (50) upper end, the second gear (59) and the second rack gear (58) company of engagement It connects；

Second press mechanism (53) includes

The second support (61) being fixed on rack (1)；

The second rocking bar (62) being rotatably connected on second support (61)；

The the second mandrel pressing plate (63) swung when being fixed in the middle part of the second rocking bar (62) and being rotated with the second rocking bar (62), it is described The end of second mandrel pressing plate (63) is abutted with the top of the second curved mandrel (52) of rotation；

It is fixed on the second driving lever (64) of the end of the second rocking bar (62)；

The third finger (65) being fixed on the second rack gear (58)；

When the second rack gear (58) is slided towards contract, one end of the third finger (65) and the second driving lever (64) is drivingly connected So that the second rocking bar (62) rotates, the second rocking bar (62) drives the second mandrel pressing plate (63) to push when rotating.
