A fixed disc is installed on the base, and the fixed disc is horizontally arranged. A power mechanism is installed on the fixed disc, and the power mechanism is connected to a connecting rod. The power mechanism drives the connecting rod to rotate around the axis of the fixed disc. A roller is installed on the connecting rod, and the roller is located on the side of the fixed disc. The first limiting strip and the second limiting strip which are parallel to each other are fixed on the base. A blocking block is arranged in the area clamped by the first limiting strip and the second limiting strip. The side of the first limiting strip close to the second limiting strip is tangent to the fixed disc. A pushing and pulling device is installed on the base, and the pushing and pulling device is located on the side of the second limiting strip far from the first limiting strip. The pushing and pulling device is connected to a pressing block, and the pushing and pulling device drives the pressing block to horizontally move along the direction perpendicular to the first limiting strip. An opening window allowing the pressing block to pass through is arranged on the second limiting strip.

[0006] Preferably, the power mechanism consists of a servo motor and a reducer. The servo motor is fixed on the fixed disc, the servo motor is connected to the reducer, and the reducer is connected to the connecting rod.

[0007] Preferably, the pushing and pulling device is an electric cylinder or a pneumatic cylinder.

[0008] Preferably, an auxiliary block is fixed on the base, and an adjusting bolt is screwed on the auxiliary block. The end of the adjusting bolt is fixed to a blocking block, which is horizontally cylindrical and moves with the adjusting bolt.

[0009] Preferably, a first arc-shaped groove is provided on the side of the pressing block close to the first limiting strip.

[0010] Preferably, a second arc-shaped groove is provided on the wheel surface of the roller.

Detailed Embodiment

[0017] Refer to Figure 1 、 Figure 2 、 Figure 3, the U-shaped bolt forming device of the present utility model is used to bend a straight screw rod with threads at both ends into a U-shaped bolt, and includes a base 1, a fixed disc 2, a first limiting strip 11, a second limiting strip 12, a blocking block 17, a pressing block 4, a pushing and pulling device 41, a power mechanism, a connecting rod 31, and a roller 3. A fixed disc 2 is installed on the base 1, and the fixed disc 2 is horizontally arranged. A power mechanism is installed on the fixed disc 2. The power mechanism is connected to a connecting rod, and the power mechanism drives the connecting rod 31 to rotate around the axis of the fixed disc 2. A roller 3 is installed on the connecting rod 31, and the roller 3 is located on the side of the fixed disc 2. The first limiting strip 11 and the second limiting strip 12 which are parallel to each other are fixed on the base 1. A blocking block 17 is arranged within the area clamped by the first limiting strip 11 and the second limiting strip 12. The side of the first limiting strip 11 close to the second limiting strip 12 is tangent to the fixed disc 2. A pushing and pulling device 41 is installed on the base 1, and the pushing and pulling device 41 is located on the side of the second limiting strip 12 away from the first limiting strip 11. The pushing and pulling device 41 is connected to a pressing block 4, and the pushing and pulling device 41 drives the pressing block 4 to horizontally move along the direction perpendicular to the first limiting strip 11. An opening window 13 allowing the pressing block 4 to pass through is provided on the second limiting strip 12.

[0018] The power mechanism is composed of a servo motor 33 and a reducer 32. The servo motor 33 is fixed on the fixed disc 2. The servo motor 33 is connected to the reducer 32, and the reducer 32 is connected to the connecting rod.

[0019] The pushing and pulling device 41 is an electric cylinder or a pneumatic cylinder.

[0020] An auxiliary block 15 is fixed on the base 1. An adjusting bolt 16 is screwed on the auxiliary block 15, and the end of the adjusting bolt 16 is fixed to the blocking block 17. The blocking block 17 is in a horizontally placed cylindrical shape, and the blocking block 17 moves along with the adjusting bolt 16.

[0021] A first arc-shaped groove 40 is provided on the side of the pressing block 4 close to the first limiting strip 11, and the first arc-shaped groove 40 is adapted to the straight screw rod.

[0023] The working process of the present utility model:

[0024] During the working process of the U-bolt forming device of the present utility model, according to the length of the U-bolt, the blocking block 17 is adjusted to an appropriate position by adjusting the adjusting bolt 16. The straight screw rod is inserted between the first limiting strip 11 and the second limiting strip 12. During the insertion process, the straight screw rod passes through the area clamped by the fixed disc 2 and the roller 3. Both the fixed disc 2 and the roller 3 are in contact with the straight screw rod. The straight screw rod is inserted until it is blocked by the blocking block 17. Then, the pushing and pulling device 41 drives the pressing block 4 to move until the pressing block 4 and the first limiting strip 11 clamp the straight screw rod. Then, the power mechanism drives the connecting rod 31 to rotate, and the roller 3 also rotates with the connecting rod 31. The roller 3 gradually bends the straight screw rod and finally bends the straight screw rod into a U-bolt. After the bending is completed, the pushing and pulling device 41 drives the pressing block 4 to reset, and then the U-bolt is taken out.

[0025] The above embodiments are illustrative of the present utility model, not restrictive thereof. Any simple transformation of the present utility model falls within the protection scope of the present utility model.
