A bending arm rotatably mounted on the processing platform rotates around the axis of the fulcrum, and a bending pressure component detachably fixed on the bending arm to apply bending force to the free end of the pipe. Addressing the problems of existing bending machines requiring power and being inconvenient to move, this utility model has the advantages of being manually driven and adaptable to various working environments. However, in the prior art, after processing each rectangular tube, it is necessary to manually remove the rectangular tube before bending the next one, resulting in low work efficiency.

The locking block 32.2 is driven to move horizontally by a first cylinder 32.5.

[0042] The bending mechanism 3 also includes a conveying assembly 33, which is used to drive the rectangular tube 4 into the first groove 32.3;

[0043] The conveying assembly 33 includes a conveying wheel 33.1, which is located on the side of the positioning block 32.1 with a first groove 32.3. The conveying wheel 33.1 is driven by a conveying motor 33.2. Two stops 33.3 are provided on the side of the conveying wheel 33.1 away from the positioning block 32.1. The two stops 33.3 are arranged at intervals and are fixedly installed on the top of the worktable 1.

[0044] The transmission wheel 33.1 has a second groove 33.4 on its surface, and a sensor 33.5 is disposed in the second groove 33.4;

[0045] The rotating rod 31.2 is equipped with a second cylinder 31.5 and a push plate 31.6, which are arranged vertically. The push plate 31.6 is fixedly mounted on the piston end of the second cylinder 31.5, and the cylinder body of the second cylinder 31.5 is fixedly mounted on the rotating rod 31.2. The second cylinder 31.5 drives the push plate 31.6 to move up and down. The push plate 31.6 is located between the roller 31.3 and the baffle 31.1.

[0046] A cleaning assembly 34 is provided on the rotating rod 31.2. The cleaning assembly 34 includes a cleaning plate 34.1 fixedly mounted on the rotating rod 31.2. The cleaning plate 34.1 is provided with bristles 34.2, and the bristles 34.2 abut against the wheel surface of the roller 31.3.

[0047] An air pipe 34.3 is vertically fixed on the rotating rod 31.2, and a fan blade 34.4 is installed inside the air pipe 34.3. The fan blade 34.4 is mounted on the central shaft of the roller 31.3.

[0048] The rotating rod 31.2 is provided with a plurality of air holes 34.5, which are evenly distributed circumferentially around the axis of the air pipe 34.3. The air holes 34.5 are connected to the air pipe 34.3, and the function of the air holes 34.5 is to facilitate air flow and act on the roller 31.3.

[0049] Working principle:

[0050] The rectangular tube 4 is manually placed on the top of the workbench 1 and moved through the two stops 33.3 to the bottom of the transmission wheel 33.1. According to calculation, the rectangular tube 4 abuts against the two stops 33.3 respectively, and there is a gap between the transmission wheel 33.1 and the rectangular tube 4 through the second groove 33.4 to avoid affecting the manual pushing of the rectangular tube 4.

[0051] Subsequently, the transmission wheel 33.1 is driven to rotate by the transmission motor 33.2. When the transmission wheel 33.1 rotates, its surface intermittently abuts against the top of the rectangular tube 4. Through friction, the transmission wheel 33.1 drives the rectangular tube 4 towards the positioning block 32.1, causing the rectangular tube 4 to insert into the first groove 32.3 and abut against the inner wall of the first groove 32.3. Simultaneously, the rectangular tube 4 abuts against the wheel surface of the roller 31.3 and the baffle 31.1. At the same time, the positioning block 32.1 is inserted into the rectangular tube. The rectangular tube 4 has an inner cavity. In fact, the positioning block 32.1 matches the rectangular block, so that the positioning block 32.1 is in contact with the inner wall of the rectangular tube 4. Through calculation, the rectangular tube 4 is separated from the stop block 33.3 at this time. In addition, the rectangular tube 4 is detected by the sensor 33.5. When the sensor 33.5 detects the rectangular tube 4, the second groove 33.4 is at the bottom of the transmission wheel 33.1. That is, there is a gap between the transmission wheel 33.1 and the rectangular tube 4, so as to avoid the transmission wheel 33.1 and the rectangular tube 4 abutting against each other and affecting the bending of the rectangular tube 4.

[0052] Next, the drive shaft 2 rotates, causing the rotating rod 31.2 and the roller 31.3 to rotate synchronously. During the rotation of the roller 31.3, the rectangular tube 4 is squeezed, which causes the mounting baffle 31.1 of the rectangular tube 4 to deform, that is, the rectangular tube 4 is bent. The bending angle of the rectangular tube 4 is controlled according to the rotation angle of the drive shaft 2. During the bending process of the rectangular tube 4, the cooperation between the locking block 32.2 and the rectangular tube 4, as well as the squeezing of the rectangular tube 4 by the roller 31.3 and the baffle 31.1, support the rectangular tube 4 and prevent it from falling from the drop chute 31.4 before the bending is completed.

[0053] After the rectangular tube 4 is bent, the first cylinder 32.5 drives the locking block 32.2 to move completely into the slot 32.4 and separates the locking block 32.2 from the rectangular tube 4. Then, the second cylinder 31.5 drives the push plate 31.6 to descend, causing the push plate 31.6 to push the rectangular tube 4 down. At this time, the rectangular tube 4 falls from the drop chute 31.4. A collection container can be placed under the drop chute 31.4 in advance to collect the bent rectangular tube 4. The shape of the drop chute 31.4 can be designed according to the size and bending angle of the rectangular tube 4 so that the bent rectangular tube 4 can fall from the drop chute 31.4.

[0054] In addition, when the roller 31.3 bends the rectangular tube 4, it rotates on the side wall of the rectangular tube 4 through friction. That is, during the bending process, the roller 31.3 rotates around the drive shaft 2 while also rotating on its own axis. The brush bristles 34.2 brush away the impurities that stick to the roller 31.3 on the rectangular tube 4, thus cleaning the roller 31.3 and preventing impurities from affecting the bending effect. At the same time, the rotation of the roller 31.3 drives the fan blade 34.4 to rotate, so that the air in the air pipe 34.3 acts on the roller 31.3, improving the removal effect of impurities on the roller 31.3.

[0055] Of course, this equipment is not limited to bending square and rectangular tubes 4, but can also be used for bending round tubes or other shaped pipes or solid rods;

[0056] In summary, this high-efficiency square and rectangular tube bending equipment only requires placing the square and rectangular tube 4 on the workbench 1, and the semi-automatic feeding can be achieved by rotating the conveyor wheel. After bending is completed, the square and rectangular tube 4 is automatically unloaded by separating the locking block 32.2 from the square and rectangular tube 4 and pushing the square and rectangular tube 4 down with the push plate 31.6. In this way, the bending efficiency of the square and rectangular tube 4 is improved. Moreover, through multiple bending mechanisms 3, multiple square and rectangular tubes 4 can be bent at the same time, which further improves the bending efficiency of the square and rectangular tube 4.
