[0025] The lifting mechanism includes a first hydraulic cylinder 7 fixedly arranged on the upper inner side of the top frame 6, the telescopic end of the first hydraulic cylinder 7 is connected to the bending member, the bending member includes a moving seat 38 fixedly installed at the telescopic end of the first hydraulic cylinder 7, a main driving shaft 19 is arranged inside the moving seat 38, a pressing wheel 40 is arranged outside the front end of the main driving shaft 19, and a fixed pipe mechanism is arranged on one side of the upper end surface of the moving seat 38;

[0026] like Figure 3 As shown, the movable seat 38 can move synchronously with the lifting and lowering movement of the first hydraulic cylinder 7, thereby prompting the pressure wheel 40 to control the bending angle at the bending angle of the square tube, and the pressure wheel 40 can also cooperate with the two sets of side wheels 9. When the square tube is bent, it can move by itself under the rolling transportation of the side wheels 9 and the pressure wheel 40.

[0027] The fixed pipe mechanism includes a U-shaped frame 20 fixedly mounted on one side of the upper end surface of the moving seat 38, the U-shaped frame 20 is connected to the slide 8 through a set driving mechanism, a moving ring 36 is fixedly mounted on the lower end surface of the slide 8, a chuck 31 is fixedly sleeved on the outer side of the moving ring 36, an arc groove 30 is opened inside the chuck 31 and close to the lower side of both sides, and a rotating shaft 32 is installed inside the two arc grooves 30, and a swing mechanism is arranged on the outer side of the two rotating shafts 32, and the driving mechanism includes a screw rod 39 rotatably mounted on the inner side of the U-shaped frame 20, a second motor 15 is fixedly arranged on one end of the screw rod 39, the second motor 15 is fixedly connected to the U-shaped frame 20, the moving ring 36 and the screw rod 39 are threadedly matched, a limiting groove 37 is opened on the upper surface of the U-shaped frame 20, and the slide 8 slides inside the limiting groove 37;

[0028] like Figure 1 , Figure 2 and Figure 6 As shown, when the second motor 15 drives the screw rod 39 to rotate, the movable ring 36 reciprocates outside the screw rod 39 under the sliding positioning of the slide 8 and the limiting groove 37, so that the movable ring 36 and the chuck 31 can approach the square pipe;

[0029] The purpose of providing the arc groove 30 at the chuck 31 and arranging the rotating shaft 32 inside the arc groove 30 is to allow the swing mechanism to fine-tune the angle, thereby assisting the use of the pressing wheel 40.

[0030] The swing mechanism includes a swing rod 25 rotatably sleeved on the outside of the rotating shaft 32, a mounting rod 22 is inserted into the lower part of the swing rod 25, a support rod 28 is arranged on the outside of the mounting rod 22 and at the front end of the swing rod 25, a cylinder 21 is fixedly arranged on the upper outside of the support rod 28, a slide seat 29 is fixedly arranged on the telescopic end of the cylinder 21, the slide seat 29 and the support rod 28 are slidably matched, a vertical rod 34 is fixedly arranged on the upper end surface of the slide seat 29 away from the cylinder 21, a sliding sleeve 35 is slidably installed on the outside of the vertical rod 34, a first support wheel 26 and a second support wheel 27 are arranged on the outer wall of one side of the slide seat 29 and the sliding sleeve 35, a clamping rod 33 is fixedly arranged on the outside of the two swing rods 25 and near the middle, and a collar 24 is rotatably sleeved on the outside of the two clamping rods 33, and the two sets of collars 24 are connected by a bidirectional telescopic rod 23;

[0031] like Figure 4 and Figure 5 As shown, the swing rod 25 can be driven by the telescopic movement of the bidirectional telescopic rod 23 and the collar 24, and can rotate with the clamping rod 33 of the swing rod 25, so that when the bidirectional telescopic rod 23 is extended and retracted, the angle between the two swing rods 25 is adjusted accordingly, so as to reduce the curvature of the pressing wheel 40 when bending a square tube of a certain length, and avoid obvious bending angles;

[0032] Under the lifting and lowering movement of the cylinder 21, the slide 29 and the first support wheel 26 can flexibly adjust the fit between the square tube, and the second support wheel 27 can be guided by the rolling of the side wheel 9, so that the square tube can move up by itself through the sliding sleeve 35 when being guided to move, thereby flexibly controlling the bending process.

[0033] The pipe clamping mechanism includes a guide rod 3 slidably mounted on an edge of one side of the inner side of the mounting frame 5, a limit rod 4 is fixedly arranged on the upper end of the outer side of the guide rod 3, an end of the guide rod 3 away from the limit rod 4 is connected to a second hydraulic cylinder 11 through a connecting rod 14, a frame seat 12 is fixedly arranged at the rear end of the second hydraulic cylinder 11, a first motor 13 is fixedly arranged on the upper end of the frame seat 12, a main gear 18 is sleeved on the output end of the first motor 13, and the main gear 18 is meshedly connected with two sets of side gears 17;

[0034] like Figure 2 As shown, the second hydraulic cylinder 11 can move by driving the connecting rod 14 to drive the guide rod 3 to move toward the front end of the mounting frame 5. When processing the square pipe, the limit rod 4 limits the head and tail ends on one side, thereby facilitating the processed square pipe to be automatically moved away from the front end of the mounting frame 5 under the transmission of the side wheel 9.

[0035] The pipe rack mechanism includes a front plate 2 fixedly mounted on the outer side of the front end of the workbench 1, and roller racks 10 are fixedly arranged on both sides of the upper end surface of the front plate 2;

[0036] like Figure 1 and Figure 2 As shown, the front plate 2 is used to install the roller frames 10 on both sides. When the square tube is being processed, the square tube to be processed can be placed on the upper surface of one side of the roller frame 10.

[0037] Working principle: When in use, the square pipe enters the outer surface of the adjacent side wheel 9 from one end of the roller frame 10, and then the first hydraulic cylinder 7 drives the moving seat 38 to move downward. According to the bending needs of the square pipe, the moving seat 38 and the pressure wheel 40 are arranged in the middle of the upper ends of the two sets of side wheels 9, and the corresponding second hydraulic cylinder 11 drives the connecting rod 14 to move to the front end, so that the two limit rods 4 are located on the rear side of the square pipe, and the front and rear ends of the square pipe are limited. Then the first motor 13 drives the main gear 18 to rotate, and the main gear 18 is engaged with the side gears 17 on both sides. The side gear 17 drives the side drive shaft 16 to rotate, and the side wheel 9 outside the side drive shaft 16 will transport the square pipe to the other end. At the same time, the second motor 15 drives the screw rod 39 to rotate, so that the moving ring 36 moves toward one end of the square tube, and the first support wheel 26 is adjusted by the cylinder 21 to press against the lower surface of the lower end of the square tube and close to the pressing wheel 40. The second support wheel 27 at the upper end of the vertical rod 34 is stuck above the square tube during the process. The two sets of side wheels 9, the first support wheel 26 and the second support wheel 27 cooperate with the rolling of the square tube, and in the process, the pressing force of the pressing wheel 40 is reduced to ensure that the midpoint of the bending of the square tube can be controlled when the square tube is bent. The two sets of side wheels 9 are rolled out during the bending process, so that the bending process of the square tube can be more flexible, and the two swing arms 25 can adjust the distance between them and the pressing wheel 40 according to actual needs with the drive of the two-way telescopic rod 23, so as to meet the use of square tubes with longer lengths.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
