[0025] like Figures 1 to 4 As shown, a specific embodiment of the utility model provides a hydraulic bending mold, including a base plate 1, the top of the base plate 1 is fixedly connected to a rear baffle 2, and one side of the rear baffle 2 is provided with a mold assembly for rapid forming of U-shaped round steel. By setting the mold assembly, the U-shaped round steel can be quickly formed, so there is no need for the staff to repeatedly adjust the bending angle, and multiple steels can be formed at the same time, thereby improving efficiency. The mold assembly includes a lower mold 3 fixedly mounted on the top of the base plate 1, a forming port 4 is provided on the lower mold 3, a round steel 5 for forming is placed on the top of the lower mold 3, an upper mold 6 is provided on the top of the lower mold 3, and also includes a movable buckle group provided on the lower mold 3 for determining the number of formed round steels 5. By setting the movable buckle group, the number of round steels 5 to be formed can be determined when forming, thereby meeting the bending requirements of round steels 5 with different numbers.

[0026] like Figures 1 to 4 As shown, specifically, the rear baffle 2 is in close contact with the lower mold 3, and a scale line 7 is provided on the rear baffle 2. When the round steel 5 is bent, multiple round steels 5 are placed on the top of the lower mold 3. The placement position of the round steel 5 is adjusted by reference to the scale line 7. The movable buckle group includes a limit groove 8 and a movable block 9. The limit groove 8 is provided on the lower mold 3. The movable block 9 is slidably connected to the limit groove 8, and the movable block 9 is adapted to the limit groove 8. A threaded rod 10 is threadedly connected to the movable block 9, and the threaded rod 10 is rotatably connected to the lower mold 3 and the rear baffle 2. The threaded rod The end of 10 is fixedly connected with a rotating block 11, and the rotating block 11 is provided with an anti-slip rubber pad. The setting of the anti-slip rubber pad can increase friction so that the staff can better rotate the rotating block 11, and the rotating rotating block 11 drives the threaded rod 10 to rotate, so that the rotation of the threaded rod 10 drives the moving block 9 to move in the limiting groove 8, and then the movement of the moving block 9 can adjust the distance between it and the rear baffle 2. The number of round steels 5 to be formed at one time can be met according to the adjustment of the distance, so that the round steels 5 to be formed at one time are at the top of the lower mold 3 and are located between the moving block 9 and the rear baffle 2.

[0027] like Figures 1 to 4As shown, specifically, the bottom plate 1 is fixedly connected with a support plate 12, and a hydraulic cylinder 13 is fixedly installed on the support plate 12, and a connecting plate 14 is fixedly connected to the push rod of the hydraulic cylinder 13, and the connecting plate 14 drives the bottom end to be fixedly connected to the mold rod 15, and the upper mold 6 is fixedly connected to the mold rod 15, and a reinforcing plate 16 is fixedly connected between the connecting plate 14 and the mold rod 15. After the round steel 5 to be formed is placed, the hydraulic cylinder 13 is started to push the connecting plate 14 at the bottom end to make the mold rod 15 move downward, and the mold rod 15 moves downward to push the upper mold 6 at the bottom end to move downward and gradually approach the round steel 5 at the top of the lower mold 3. Under the pressure of the upper mold 6, the round steel 5 gradually sinks into the forming port 4, and in the process of the gradual downward movement of the upper mold 6, the round steel 5 is gradually formed into a U-shaped round steel. In this process, there is no need for the staff to repeatedly adjust the bending angle. Multiple round steels 5 are formed at one time under the action of the upper mold 6 and the lower mold 3. An opening 17 is provided in the lower mold 3, and the opening 17 is connected to the forming port 4. A discharge rack 18 is provided on the bottom plate 1, and a plurality of conveying rods 19 are provided on the discharge rack 18, and a driving member for rotating the conveying rod 19 is provided in the discharge rack 18. When the round steel 5 is pressed to the bottom end of the lower mold 3 pair after forming, due to the different lateral widths of the upper mold 6 and the mold rod 15, the vertical rods at both ends of the opening of the formed U-shaped round steel cannot clamp and touch the mold rod 15, so that it is difficult to form a supporting force, and then when the mold rod 15 drives the upper mold 6 to move upward and reset, it is convenient for the U-shaped round steel to separate from it. Due to the opening of the opening 17, the detached U-shaped round steel tilts and slides in the opening 17 and contacts the conveying rod 19. Under the action of the driving member, the conveying rod 17 can be rotated in the discharge rack 18, and then the rotating rotating rod 19 can gradually transport the tilted U-shaped round steel, thereby achieving the purpose of unloading the U-shaped round steel in the lower mold 3.
