At the same time, the lower bending press 7 is driven to move by the hand wheel 6, threaded rod 4 and slider 5, so as to switch different types of presses for use. When adjusting the position of the lower bending press 7, the hand wheel 6 is rotated, and the hand wheel 6 drives the threaded rod 4 to rotate. The threaded rod 4 drives the lower bending press 7 to move through the slider, so as to adjust the position of the lower bending press 7. The hydraulic cylinder 10 is used to control the upper bending press 12 to move up and down, so as to cooperate with the lower bending press 7 to bend the steel of the floor beam. The rotating mechanism 13 can control the rotation of the upper bending press 12, so as to change the press used on the upper bending press 12 to cooperate with different presses on the lower bending press 7.

[0025] Example 2

[0026] like Figure 3~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a lower bending press 7, which includes a bottom plate 71 fixed between the top walls of the two sliders 3, and a plurality of mounting grooves are evenly opened on the top wall of the bottom plate 71, and mounting plates 72 are fixed in the mounting grooves by bolts, and different types of concave presses 73 are fixed on the mounting plates 72, and a positioning line 74 is set on the side wall of the bottom plate 71 corresponding to the position of the concave press 73, and a reference line 14 is set on the top wall of the base 1 corresponding to the position of the upper bending press 12.

[0027] The lower bending press 7 is provided with a plurality of different types of commonly used concave presses 73. The lower bending press 7 is driven to move by the provided hand wheel 6, threaded rod 4 and slider 5, so that different concave presses 73 can be cut for use without replacing the concave press 73. The operation is simple and convenient. At the same time, the provided positioning line 74 and reference line 14 can ensure that the concave press 73 moves to the bottom of the upper bending press 12.

[0028] The upper bending press 12 includes a mounting column 121, both ends of which are fixed with a rotating shaft 122, the rotating shaft 122 is rotatably connected to the inner wall of the n-shaped frame 11, and a plurality of convex presses 123 are fixed to the side wall of the mounting column 121 by bolts.

The driving motor 135 is a stepping motor or a servo motor.

[0031] In this embodiment, the rotating mechanism 13 is used to drive the upper bending press 12 to flip, so that the convex press 123 corresponding to the concave press 73 flips to the bottom. When the rotating mechanism 13 is working, the driving motor 135 drives the worm 134 to rotate, and the worm 134 drives the rotating shaft 122 to rotate through the worm gear 133 and the mounting shaft 132, thereby driving the convex press 123 on the mounting column 121 to rotate. The driving motor 135 adopts a stepping motor or a servo motor, which can ensure the rotation angle and ensure that the convex press 123 at the bottom is in a horizontal state.

[0032] When the utility model is used, the position of the corresponding concave pressing tool 73 is first adjusted according to the type of bending required, so that the required concave pressing tool 73 moves to the position of the reference line 14. When adjusting, the hand wheel 6 is turned, and the hand wheel 6 drives the threaded rod 4 to rotate. The threaded rod 4 drives the lower bending pressing tool 7 to move through the slider, thereby adjusting the position of the concave pressing tool 73, and then the upper bending pressing tool 12 is driven to rotate through the rotating mechanism 13, so that the corresponding convex pressing tool 123 rotates to the bottom.
