The bending machine in the prior art generally includes an operating platform, a large wheel and a small wheel installed on the operating platform. The pipe fitting is inserted between the large wheel and the small wheel, and the small wheel is rotated so that the small wheel rotates around the large wheel to form a bend in the pipe fitting. However, this operation requires manual insertion of the pipe fitting between the large wheel and the small wheel, which is time-consuming and labor-intensive. In addition, according to the different diameters of the pipes, the large wheel and the small wheel of the corresponding specifications need to be replaced, resulting in low production efficiency.

The driving plate can drive the first round rod and the second round rod to move up and down through the connecting component, thereby changing the groove spacing of the entire groove wheel to adapt to pipes of different diameters. The triggering component can drive the second round rod to move away from the first round rod, so that the two integral groove wheels form an interval to facilitate the pipe to roll between the two integral groove wheels. The second round rod can be returned to its position through the resetting component to initially clamp the pipe.

When the pipe fitting enters between the two integral groove wheels, the driving rod moves downward, and the second round rod gradually returns to its position under the drive of the reset assembly to clamp the pipe fitting, and then the driving plate is rotated by the swing mechanism. The driving groove on the driving plate drives the second round rod to rotate, so that the integral groove wheel matched with the second round rod rotates around the integral groove wheel matched with the first round rod, thereby bending the pipe fitting, and when the driving plate rotates, the yielding arc groove can provide relative rotation space for the driving rod to prevent jamming and hindering the rotation of the driving plate.

Since the swing rod is arranged inside the driving plate, it can drive the driving plate to swing. The driving groove on the driving plate can drive the first round rod to rotate around the first round tube, so that the integral groove wheel related to the second round rod rotates around the integral groove wheel corresponding to the first round rod, and the pipe fitting between the two integral groove wheels can be bent. The limit plate can prevent the swing rod from slipping out of the driving rod.

[0030] The working principle and beneficial effects of the present invention are: 1. The automatic feeding mechanism in the present invention can temporarily store pipe fittings and feed a single pipe fitting, and can feed the pipe fitting into the adaptive bending mechanism through the material guiding mechanism for bending. The specific linkage mechanism can drive the pulley assembly to move away from the fixed wheel assembly first, so that a gap is formed between the fixed wheel assembly and the pulley assembly, and the pipe fitting at the material guiding mechanism can enter between the fixed wheel assembly and the pulley assembly, and then the pulley assembly returns to its position and clamps the pipe fitting with the fixed wheel assembly. When the pipe fitting is between the fixed wheel assembly and the pulley assembly, the pulley assembly is driven to rotate around the fixed wheel assembly through the swing mechanism, so that the pipe fitting is bent. The degree of automation is high, and multiple pipe fittings only need to be fed to the automatic feeding mechanism manually, which improves production efficiency and can adapt to pipe fittings of different diameters.

[0031] 2. The support frame in the present invention is used to support the operating platform. The operating platform serves as the main structure for bending pipe fittings. The fixed wheel assembly, pulley assembly and material guide mechanism are all installed on the upper part thereof, which can realize automatic loading and adaptively clamp and bend pipe fittings according to their diameters. The drive of the linkage mechanism realizes the linkage of pipe loading and bending.

[0032] 3. After the bending of the pipe is completed, the push plate can push the pipe to the outside of the operating platform by pushing the power part. A receiving frame can be set at the bottom of the operating platform to receive the pipe after bending and realize automatic unloading.

[0033] 4. When the driving rod moves upward, the trigger block on the driving rod contacts the driven block. Since the driven block has a sliding inclined portion, the driving rod moves vertically upward, so that after the trigger block contacts the sliding inclined portion, the driven block is forced to drive the second round rod to move along the straight groove portion in a direction away from the first round rod, so that a gap is formed between the two integral groove wheels, which is convenient for the pipe fitting to enter between the two integral groove wheels. When the pipe fitting enters between the two integral groove wheels, the driving rod moves downward, and the second round rod gradually returns to its position under the drive of the reset assembly to clamp the pipe fitting. Then, the driving plate is rotated through the swing mechanism, and the driving groove on the driving plate drives the second round rod to rotate, so that the integral groove wheel matched with the second round rod rotates around the integral groove wheel matched with the first round rod, thereby bending the pipe fitting. When the driving plate rotates, the yielding arc groove can provide relative rotation space for the driving rod to prevent jamming and hindering the rotation of the driving plate.

[0034] 5. The swing power member in the present invention can rotate relative to the rotating seat, which is equivalent to a hinged manner. Its extension can drive the swing rod to move. Since the swing rod is inserted into the driving plate, it can drive the driving plate to swing. The driving groove on the driving plate can drive the first round rod to rotate around the first round tube, so that the integral groove wheel related to the second round rod rotates around the integral groove wheel corresponding to the first round rod. The pipe fitting between the two integral groove wheels can be bent, and the limit plate can prevent the swing rod from slipping out of the driving rod. BRIEF DESCRIPTION OF THE DRAWINGS

The specific linkage mechanism 500 can drive the pulley assembly 320 to first move away from the fixed wheel assembly 310, so that a gap is formed between the fixed wheel assembly 310 and the pulley assembly 320, and the pipe fittings at the material guiding mechanism 400 can pass through the above gap to enter between the fixed wheel assembly 310 and the pulley assembly 320, and then the pulley assembly 320 returns to its position and clamps the pipe fittings with the fixed wheel assembly 310. When the pipe fittings are between the fixed wheel assembly 310 and the pulley assembly 320, the pulley assembly 320 is driven by the swing mechanism 600 to rotate around the fixed wheel assembly 310, so that the pipe fittings are bent. The degree of automation is high, and multiple pipe fittings only need to be fed into the automatic feeding mechanism 200 manually, which improves production efficiency and can adapt to pipe fittings of different diameters.

The blocking plate 330 is used to support the rear end of the pipe when the pipe is bent, thereby facilitating the bending of the pipe. The retractable blocking plate 330 and the material blocking plate 318 can be retracted and prevented from moving when the pushing plate 720 pushes the pipe, so that the material can be unloaded smoothly.

[0051] Reference Figure 1 and Fig. 9 The linkage mechanism 500 in this embodiment includes a reciprocating power member 510 fixed on the support frame 110, the reciprocating power member 510 is connected to a driving rod 520, a driving plate 530 is passed through the driving rod 520, a push-pull component is provided between the driving rod 520 and the driving plate 530, a connecting component connecting the first round rod 317 and the second round rod 325 is provided on the driving plate 530, and also includes a triggering component for triggering the movement of the second round rod 325 and a resetting component for pushing the second round rod 325 to reset.

[0052] The reciprocating power member 510 can directly drive the driving rod 520 to move up and down. The driving rod 520 is inserted into the driving plate 530. The driving plate 530 can be intermittently driven to move up and down by the pushing component. The driving plate 530 can drive the first round rod 317 and the second round rod 325 to move up and down through the connecting component, thereby changing the groove spacing of the entire groove wheel to adapt to pipes of different diameters. The triggering component can drive the second round rod 325 to move away from the first round rod 317, so that the two integral groove wheels form an interval to facilitate the pipe to roll between the two integral groove wheels. The second round rod 325 can be returned to its position through the resetting component to initially clamp the pipe. The reciprocating power member 510 can also use an electric cylinder or an oil cylinder, with the electric cylinder being preferred.

[0053] Specifically, a sliding hole 531 is provided on the driving plate 530, and the driving rod 520 is inserted into the sliding hole 531. The push-pull assembly includes a pull-back block 541 and a lifting block 542 provided on the driving rod 520, and the lifting block 542 and the pull-back block 541 are located on both sides of the driving plate 530; the connecting assembly includes a first through hole 532 provided on the driving plate 530 for passing the first round rod 317, and the lower ends of the first round rod 317 and the second round rod 325 are loosely fixed to the driving plate 530 through two nuts 533 after passing through the driving plate 530, and the two nuts 533 are located on both sides of the driving plate 530. The two nuts 533 are not in a fastened state with the driving plate 530, and there is a certain gap, especially the two nuts 533 on the second round rod 325 should not be close to the driving plate 530, so as to facilitate the movement of the second round rod 325 relative to the driving plate 530.

[0054] Specifically, the trigger assembly includes an actuated block 551 arranged at the lower end of the second round rod 325, the actuated block 551 is provided with a sliding inclined portion 552, the driving rod 520 is provided with a trigger block 553 that cooperates with the actuated block 551, the trigger block 553 is located at the lower part of the lifting block 542, the driving plate 530 is provided with a straight groove portion 554 for the second round rod 325 to slide, the straight groove portion 554 is provided with a driving groove 555 at one end close to the first round rod 317, and the driving plate 530 is also provided with a yielding arc groove 534. When the driving rod 520 moves upward, the trigger block 553 on the driving rod 520 contacts the actuated block 551. Since the actuated block 551 has a sliding inclined portion 552, the driving rod 520 moves vertically upward, so that the trigger block 553 contacts the sliding inclined portion 552, forcing the actuated block 551 to drive the second round rod 325 to move away from the first round rod 317 along the straight groove portion 554, so that a gap is formed between the two integral groove wheels, which facilitates the pipe fitting to enter between the two integral groove wheels. When the pipe fitting enters between the two integral groove wheels, the driving rod 520 moves upward vertically. The rod 520 moves downward, and the second round rod 325 gradually returns to its original position under the drive of the reset assembly to clamp the pipe fitting. Then, the driving plate 530 is rotated through the swing mechanism 600. The driving groove 555 on the driving plate 530 drives the second round rod 325 to rotate, so that the integral groove wheel matched with the second round rod 325 rotates around the integral groove wheel matched with the first round rod 317, thereby bending the pipe fitting. When the driving plate 530 rotates, the yield arc groove 534 can provide relative rotation space for the driving rod 520 to prevent jamming and hindering the rotation of the driving plate 530.

[0055] Specifically, the reset assembly includes a mounting block 561 fixed to the lower part of the operating platform 120, one end of a reset spring 562 is fixed to the mounting block 561, the other end of the reset spring 562 is connected to a sliding sleeve 563, and the sliding sleeve 563 is sleeved on the second round rod 325. When the second round rod 325 moves in a direction away from the first round rod 317 driven by the driven block 551, the reset spring 562 is compressed, and when the driving rod 520 moves in the reverse direction, the reset spring 562 releases elastic force to drive the second round rod 325 to reset, and the second round rod 325 can be moved up and down by providing the sliding sleeve 563.

[0056] The swing mechanism 600 in this embodiment includes a rotating seat 610 installed on the support frame 110, and a swing power member 620 is rotatably connected to the rotating seat 610, and the swing power member 620 is connected to a rocker rod 630. A limit plate 640 is provided on the top of the rocker rod 630 after passing through the driving plate 530. The swing power member 620 can rotate relative to the rotating seat 610, which is equivalent to a hinged manner. Its extension can drive the rocker rod 630 to move. Since the rocker rod 630 is penetrated inside the driving plate 530, it can drive the driving plate 530 to swing. The driving groove 555 on the driving plate 530 can drive the first round rod 317 to rotate around the first round tube, so that the integral groove wheel related to the second round rod 325 rotates around the integral groove wheel corresponding to the first round rod 317, and the pipe fitting between the two integral groove wheels can be bent. The limit plate 640 can prevent the rocker rod 630 from slipping out of the driving rod 520. The swing power member 620 can adopt a power member with telescopic function such as an electric cylinder.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
