The mounting plate 110 is used to connect the upper die 600, and of course, a pair of screw holes corresponding to the screw holes 111 need to be formed in the upper die 600, so that the upper die 600 can be fixed to the mounting plate 110 by bolts.
Because the cross beam 100 is a rectangular tube having a certain space therein, the leveling beam 300 is telescopically installed at the rear end of the cross beam 100, i.e., one end of the leveling beam 300 is inserted into the cross beam 100 from the rear end of the cross beam 100, so that the length of the leveling beam 300 exposed out of the cross beam 100 is adjustable, i.e., the arm of force thereof with respect to the hinge point of the cross beam 100 and the lifting beam 200 can be adjusted, and forms a lever with one end of the upper die 600 by the lever principle. In this embodiment, a reinforcing plate 140 is welded on the upper surface of the cross beam 100 near the rear end, a screw hole communicating with the interior of the cross beam 100 is provided on the reinforcing plate 140, and a locking handle 400 is installed in the screw hole, so that the upper surface of the leveling beam 300 can be locked or unlocked by rotating the locking handle 400, and the length of the arm of force is fixed. In order to quickly adjust the leveling requirements according to the upper dies 600 with different weights, scales are arranged on the upper surface of the leveling beam 300 along the length direction, and the leveling beam 300 can quickly level by adjusting the scales indicated by the rear ends of the extending cross beams 100 according to the weight of the upper dies 600.
In addition, since the leveling beam 300 directly has a large pulling friction in the cross beam 100, for this reason, the end of the leveling beam 300 inserted into the cross beam 100 is provided with a roller 330; specifically, the end of the leveling beam 300 is provided with a wheel groove 320, shaft holes are formed at both sides of the wheel groove 320, and the roller 330 is positioned in the wheel groove 320 and is fixed by a wheel shaft 340 installed in the wheel groove 320, thereby facilitating the pulling operation of the leveling beam 300. Meanwhile, in order to facilitate the operation, a handle 310 is provided at one end of the leveling beam 300 away from the cross beam 100, side handles 130 are provided on the sides of the cross beam 100 at opposite sides of the bracket 120, so that an operator can conveniently hold the leveling beam 300 with two hands, pull the leveling beam 300 to adjust the length of the arm of force thereof, and operate the cross beam 100 to mount the upper die 600 on the slider 700.

A balance bar die loader for a bending machine according to any one of claims 1-3, wherein: the cross beam (100) is provided with a bracket (120), and the lower end of the lifting beam (200) is hinged with the bracket (120) through a pin shaft (121); the upper end of the lifting beam (200) is provided with a pair of lug plates (210), and lifting trunnion (220) is arranged on the lug plates (210).
7. Use of a balance bar die loader for a bending machine according to claim 1, in connection with mounting an upper die (600) of a bending machine to a slide (700).
8. The method for using the balance bar die loader for the bending machine, which is disclosed in claim 2, comprises the following steps:
(1) mounting the upper die (600) to the mounting plate (110) by bolts;
(2) connecting the lifting end of the lifting beam (200) with lifting equipment and lifting;
(3) releasing the locking handle (400), adjusting the length of the leveling beam (300) extending out of the cross beam (100) according to the weight of the upper die (600), leveling the cross beam (100), and locking the locking handle (400);
(4) the lifting equipment drives the cross beam (100) to move, so that the upper die (600) is close to the upper die (600) mounting position on the sliding block (700);
(5) loosening an adjustable knob (550) of the fine adjustment mechanism (500), rotating a fixed knob (540), enabling an eccentric shaft (530) to rotate, fine adjusting the angle of a cross beam (100) through a first connecting rod (510) and a second connecting rod (520), enabling an upper die (600) to be aligned with the installation position on a sliding block (700), and then tightening the adjustable knob (550), so that the first connecting rod (510) and the second connecting rod (520) are relatively fixed, and enabling the angle of the cross beam (100) to be fixed;
(6) jacking the upper die (600) into the installation position, keeping the upper die stationary, and fixing the upper die (600) by adopting a pressing block (800);
(7) and loosening the bolts to separate the upper die (600) from the mounting plate (110), thereby completing the mounting of the upper die (600).
