A first forming roller 4 coaxially arranged with the main shaft 2 and a second forming roller 5 parallel to the first forming roller are provided on the forming plate 3. A raw material insertion channel 6 extending vertically is formed between the second forming roller 5 and the first forming roller 4. A stop mechanism 7 is provided at the bottom end of the raw material insertion channel 6, and a clamping mechanism 8 is provided between the stop mechanism 7 and the forming plate 3.

[0018] Further, the clamping mechanism 8 includes a left clamping wheel 81 provided on one side of the raw material insertion channel 6 and a right clamping wheel 82 provided on the other side of the raw material insertion channel 6. A clamping arm 83 and a push rod cylinder 84 are rotatably connected to the back plate 1. One end of the push rod cylinder 84 that is not connected to the back plate is hinged to one end of the clamping arm 83 that is not connected to the back plate. The right clamping wheel 82 is rotatably connected to the clamping arm 83, and the left clamping wheel 81 is rotatably connected to the back plate 1.

[0019] In this embodiment, first, the straight steel bar is inserted into the raw material insertion channel 6 in a top-down manner, and the bottom end abuts against the stopping mechanism 7. Then, the push rod cylinder 84 is operated to extend. Driven by the clamping arm 83, the right clamping wheel 82 moves towards the left clamping wheel 81 until one end of the straight steel bar is clamped. Then, the power assembly (including the motor and the reducer) is operated, the main shaft 2 rotates, and the forming plate 3 is controlled to rotate 180°. The first forming roller 4 and the second forming roller 5 bend the straight steel bar to form an inverted U-shaped structure. Finally, the clamping mechanism 8 is loosened, and the formed U-shaped lock hook can be taken out.

[0020] Embodiment 2

[0021] See Figure 1 and Figure 2 As shown, a U-shaped lock hook forming device according to this embodiment is further provided on the basis of Embodiment 1. The stopping mechanism 7 includes a movable stopping plate 71 and a fixed stopping plate 72 provided below the movable stopping plate 72. The fixed stopping plate 72 is provided on the back plate 1. A guiding column 73 extending vertically is provided on the fixed stopping plate 72. A guiding sleeve 74 is slidably connected to the guiding column 73. The movable stopping plate 71 is provided on the guiding sleeve 74.

At this time, by holding the handle 94 and pressing it downward, the camshaft 91 rotates through the lever arm 93, the cam 92 rotates, and the convex part on the cam 92 pushes the movable stop plate 71 upward. The movable stop plate 71 moves upward relative to the fixed stop plate 72, jacking up and releasing the clamping mechanism 8 and the formed U-shaped locking hook, causing its top to rise and facilitating the blanking.

[0024] The U-shaped locking hook forming device involved in the present utility model fixes one end of the bent steel bar to prevent movement during forming, so that the two ends of the formed U-shaped locking hook are aligned; and the movable stop plate can be lifted to jack up the formed U-shaped locking hook, facilitating blanking. The overall function is complete and the practicability is strong.
