In particular, since both sides of the large arc horizontal arm A4 are coupled with the joint G to the lower end of the both sides of the large arc down arm A2, when the rotation drive means K operates, it operates as an under great arc rotation and an upper great arc rotation. Circular rotation of table C can be further facilitated, which is preferable.

As shown in Figures 4a to 7b, the rotation drive means (K) is a lifting horizontal bar (K1) coupled to a hinge (H) to either side of the lower arc lower arm (A1) and the upper arc lower arm (A2) on both sides And, the support horizontal bar (K2) coupled to the hinge (H) at the lower end of the side frame (F3) and the lifting horizontal bar (K1) while being mounted on the support horizontal bar (K2) to raise and lower both sides of the lower arc down arm (A1) ) of the upper wish arc motion and the upper great arc motion of both sides great arc downward arm (A2), the under wish arc motion of both sides wish arc horizontal arm (A3) and the under great circle arc motion of both sides great arc horizontal arm (A4) and a drive body K30 for circularly rotating the pivot table C through [At this time, according to the embodiment of the present invention, the lifting horizontal bar K1 has both sides of the small arc down arm A1 and both sides of the large arc down arm ( Although it is assumed that the hinge (H) is coupled to any one of A2), the hinge (H) can be coupled to both side small arc horizontal arms (A3) or both large circle arc horizontal arms (A4) of course].

The driving force of the driving body (K30) mounted on the support horizontal bar (K2) is hinged (H) to either side of the lower arc lower arm (A1) and the lower arc lower arm (A2) on both sides through the lifting horizontal bar (K1) So that it can be transmitted to the combined lifting horizontal bar (K1), and at this time, when the driving force of the driving body (K30) is transmitted to both sides of the lower arc lower arm (A1) through the lifting horizontal bar (K1), the lifting height is relatively While there are advantages of being short and disadvantages of having to make the driving force relatively strong, when the driving force of the driving body K30 is transmitted to the both sides of the arc down arm A2 through the lifting horizontal bar K1, the driving force is relatively There is an advantage that can be weakened and a disadvantage that the lifting height must be relatively long.

And, although it was mentioned that the support horizontal bar (K2) is hinged (H) to the lower end of both side frames (F3), the support horizontal bar (K2) itself is fixed to the lower end of both side frames (F3) and then the servo It is also possible that the motor (K31) can be rolled mounted on the supporting horizontal bar (K2).

The support horizontal bar (K2) is hinged (H) coupled to both side frames (F3) or the servo motor (K31) is rolled mounted to the support horizontal bar (K2), the lifting horizontal bar (K1) is both sides of the lower arc down arm ( A1) and the vertical upward movement of the rack (K33) by the servomotor (K31) together with the hinge (H) coupled to either side of the large arc down arm (A2) up and down hinge (H) or rolling to achieve circular rotation It will be important in terms of guaranteeing it as a mechanism.

That is, it is possible to easily determine the circular rotation angle of the pivot table (C) according to the normal and reverse rotation of the servomotor (K31), and at the same time, the elevating horizontal bar (K1) is moved by the elevation of the rack (K33) by the pinion (K32). It will be important in terms of guaranteeing it as a mechanism for circular rotation by allowing it to be raised and lowered softly.

In addition, both sides of the small arc down arm (A1) can be rounded at an arc angle toward the hinge (H) coupled to both sides of the small arc horizontal arm (A3) and both sides of the large circular arc horizontal arm (A4), respectively, so that the pivot table ( C) Minimizes the change in height of the hinge (H) coupled to the upper end of the lower arc down arm (A1) on both sides during the circular arc rotation, while the change in height of the hinge (H) coupled to the upper end of the upper arc down arm (A2) on both sides is relatively maximized to accurately realize the circular rotation of the pivot table (C) (for example, if you want to bend the plate (P) at 90 °, the arc rotation angle of the pivot table (C) is set to about 45 °) This is because the bending angle of the plate (P) placed on the opposite side of the pivot table (C) is 45°.

Furthermore, the pivot table (C) is further provided with both side bar holes (C1) drilled in the longitudinal or width direction, so that when the length or width of the plate (P) is long, an angle pipe (not shown) is inserted into the both side bar holes (C1) To promote the effect of extending the length or width of the rotation table (C).

If it is necessary to adjust the distance to the group (J), it can be flexibly adjusted.

Furthermore, the elevator platform (S) is height-adjustable through the height adjusting means (N) while the LM guide (L) is coupled to the base (B), so that the height is adjusted according to the height of the bending die (J1) of the bending machine (J) By adjusting the height of the platform (S) along the LM guide (L) through the means (N), it is possible to ensure flexibility in the work site.
