[0065] An automatic steel pipe bending device, comprising a bottom plate 1 and a rear plate 2, further comprising:

[0066] A bending mechanism, provided on the rear plate 2, for bending the steel pipe;

[0067] The support plate 3 is provided on the bottom plate 1 and is fixedly connected to the support plate 3;

[0068] There are two sets of sliding mechanisms, and the two sets of sliding mechanisms are symmetrically arranged on the support plate 3;

[0069] The clamping mechanism is arranged on the sliding mechanism, and each set of sliding mechanisms is symmetrically provided with two sets of clamping mechanisms, which are used to cooperate with the sliding mechanism to clamp the bent steel pipe;

[0074] The motor 8 is provided on the base plate 1 and is fixedly connected to the base plate 1;

[0075] A bidirectional threaded rod 9 is provided on the motor 8 and fixedly connected to the output end of the motor 8;

[0081] During operation, the motor 8 drives the bidirectional threaded rod 9 to rotate forward, and the bidirectional threaded rod 9 drives the two threaded blocks 11 threadedly connected to it to approach each other, thereby realizing the mutual approach of the two clamping mechanisms on the sliding mechanism. The motor 8 drives the bidirectional threaded rod 9 to rotate reversely, and the bidirectional threaded rod 9 drives the two threaded blocks 11 threadedly connected to it to move away from each other, thereby realizing the mutual distance between the two clamping mechanisms on the sliding mechanism.

[0089] The baffle 15 is provided on the sliding block 6 and is fixedly connected to the sliding block 6;

[0090] The second telescopic rod 16 is provided on the sliding block 6 and is fixedly connected to the sliding block 6;

[0091] The limiting block 17 is provided on the sliding block 6 and is fixedly connected to the sliding block 6;

[0092] The telescopic block 18 is fixedly provided on the second telescopic rod 16 and is slidably connected to the limit block 17;

[0093] The sloped blocks 19 are fixedly arranged on both sides of the telescopic block 18, and the surface of the sloped blocks 19 close to the baffle 15 is an inclined surface;

[0094] The first rotating shaft 20 is provided on the telescopic block 18 and is fixedly connected to the telescopic block 18;

[0095] The first pulley 21 is disposed on the first rotating shaft 20 and is rotatably connected to the first rotating shaft 20 .

[0096] During operation, the second telescopic rod 16 extends, causing the telescopic block 18 to move upward, thereby causing the sloped block 19 fixedly connected to the telescopic block 18 to move upward, causing the fourth pulley 29 rollingly connected thereto to roll, thereby driving the leaf-shaped plate 25 to rotate about the second rotating shaft 23, and the leaf-shaped plate 25 can be rotated about the second rotating shaft 23, thereby cooperating with the clamping assembly to clamp the steel pipe to be bent.

[0097] The clamping assembly is arranged on the sliding block 6 and is used to cooperate with the telescopic assembly to clamp the steel pipe to be bent.

[0098] The clamping assembly comprises:

[0099] The top rod 22 is provided on the baffle 15 and is fixedly connected to the baffle 15;

[0100] The second rotating shaft 23 is provided on the top rod 22 and is fixedly connected to the top rod 22;

[0101] A second pulley 24 is provided on the second rotating shaft 23 and is rotatably connected to the second rotating shaft 23;

[0102] The blade plate 25 is provided on the second rotating shaft 23 and is rotatably connected to the second rotating shaft 23;

[0103] The third rotating shaft 26 is provided on the leaf-shaped plate 25 and is fixedly connected to the leaf-shaped plate 25;

[0104] A third pulley 27 is provided on the third rotating shaft 26 and is rotatably connected to the third rotating shaft 26;

[0105] The fourth rotating shaft 28 is provided on the leaf-shaped plate 25 and is fixedly connected to the leaf-shaped plate 25;

[0106] a fourth pulley 29, disposed on the fourth rotating shaft 28 and rotatably connected to the fourth rotating shaft 28 and rollingly connected to the ramp block 19, for cooperating with the ramp block 19 to drive the blade plate 25 to rotate about the second rotating shaft 23;

[0107] There are two clamping columns 30, and one of the clamping columns 30 is arranged between the two first pulleys 21 and fixedly connected to the first pulley 21, and the other clamping column 30 is arranged between the two third pulleys 27 and fixedly connected to the third pulley 27. The clamping column 30 is made of carbon steel metal material, so that the clamping column 30 is not easy to deform, rust or age during clamping.

[0108] When the second telescopic rod 16 retracts backward, the fourth pulleys 29 on both sides roll upward on the ramp block 19, driving the leaf plate 25 to rotate about the second rotation axis 23, causing the third pulley 27 to expand outward. When the second telescopic rod 16 extends forward, the fourth pulleys 29 on both sides roll downward on the ramp block 19, driving the leaf plate 25 to rotate about the second rotation axis 23, causing the third pulley 27 to retract inward. This allows the bending device to be clamped and released.

[0109] The bending mechanism comprises:

[0110] The top plate 31 is provided on the rear plate 2 and is fixedly connected to the rear plate 2;

[0111] A first telescopic rod 32 is provided on the top plate 31 and is fixedly connected to the top plate 31;

[0112] The bending rod is disposed on the first telescopic rod 32 and is fixedly connected to the first telescopic rod 32 .

[0113] During operation, the first telescopic rod 32 extends, driving the bending rod 33 downward to bend the steel pipe to be bent. The spring 14 stretches the connecting block 7 to slide in the moving block 12, and the sliding blocks 6 on both sides retract inward to share the pulling force of the steel pipe during bending.

[0114] By setting up a sliding mechanism, a bending mechanism and a clamping mechanism, the device can bend steel pipes of different lengths and thicknesses, which greatly increases the applicability of the device and reduces the processing cost of the factory for processing steel pipes of different sizes.

[0115] Working principle: When working, the distance between the two clamping mechanisms is adjusted according to the length of the steel pipe to be bent. The specific process is that the motor 8 is started to drive the bidirectional threaded rod 9 to rotate, thereby driving the two threaded blocks 11 threadedly connected to the bidirectional threaded rod 9 to move closer to or away from each other, the threaded block 11 drives the two moving blocks 12 fixedly connected thereto to move closer to or away from each other, the moving block 12 drives the two connecting blocks 7 slidably connected thereto to move closer to or away from each other, the moving block 12 drives the sliding block 6 slidably connected thereto to move closer to or away from each other, thereby realizing the clamping mechanism fixedly connected to the sliding block 6 on the slide rail 5. They move closer to or farther away from each other to adapt to the clamping of steel pipes to be bent of different lengths; then, the second telescopic rod 16 contracts backward, and the fourth pulleys 29 on both sides roll upward on the slope block 19, driving the leaf plate 25 to rotate around the second rotation axis 23, thereby expanding the third pulley 27 outward; the second telescopic rod 16 extends forward, and the fourth pulleys 29 on both sides roll downward on the slope block 19, driving the leaf plate 25 to rotate around the second rotation axis 23, thereby shrinking the third pulley 27 inward, and the clamping column 30 is fixedly connected to the two first pulleys 21 and the third pulley 27 on both sides of it, thereby clamping the steel pipe to be bent.

[0116] During bending, the first telescopic rod 32 extends, driving the bending rod downward to bend the steel pipe to be bent. The spring 14 stretches the connecting block 7 to slide in the moving block 12, and the sliding blocks 6 on both sides retract inward to share the pulling force of the steel pipe during bending.

[0117] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
