Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, and more specifically, to an auxiliary material support mechanism for a serpentine pipe bending machine. Background Technology

[0002] A serpentine pipe bending machine is a specialized piece of equipment used to manufacture serpentine pipes, widely applied in boiler manufacturing. It features a fixed bending die and a rotating arm that circumvents the die. The arm engages with the pipe to be processed, and bending is achieved by rotating the arm at different angles. A feeding mechanism is also located on one side of the bending die to deliver the pipe to the die, enabling continuous bending of the serpentine pipe to form a pipe bank.

[0003] However, when existing serpentine pipe bending machines bend serpentine pipes, because the swing arm is lower than the plane of the serpentine pipe, when encountering a short or large diameter serpentine pipe, part of the pipe is suspended in the air, causing the pipe at the bending die to twist. This results in poor flatness of the bent pipe and fails to meet the required standards. Utility Model Content

[0020] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0021] Example 1

[0022] Seen in Figure 1 This embodiment provides an auxiliary material support mechanism for a serpentine pipe bending machine, which includes a rotating arm 100 that rotates around a bending die. The rotating arm 100 has a mating part 101 that rotates with the bending die, and a bearing part 102 integrally formed with the mating part 101. An installation cavity 103 is formed in the bearing part 102. A clamping part 110 is telescopically provided at the installation cavity 103. A driving part 120 is provided on one side of the clamping part 110. The driving part 120 is used to drive the clamping part 110 to clamp and release the pipe to be bent. A material support part is provided on one side of the mating part 101. The material support part is used to support the bent pipe.

[0023] According to the solution provided in this embodiment, the clamping part 110 can make the pipeline abut against the bending die when the pipeline is bent, so that when the rotating arm 100 rotates, the pipeline can be bent into a serpentine shape according to the rotation angle of the rotating arm 100. The stripping part can support the bent serpentine pipeline, so that the serpentine pipeline at the rotating arm 100 is supported, so as to avoid the serpentine pipeline from twisting too much at the rotating arm 100 after bending, thereby improving the flatness of the bent serpentine pipeline.

[0024] Specifically, the drive unit 120 can drive the clamping unit 110 to clamp and release the pipeline, thereby facilitating the removal of the bent serpentine pipeline after the pipeline is cut off at the end of the serpentine pipeline bending.

[0025] The clamping part 110 includes a clamping block seat 211, and a serpentine clamping block 212 is fixedly provided at the clamping block seat 211. The end of the serpentine clamping block 212 away from the clamping block seat 211 forms an arc-shaped clamping surface 2121, which is used to abut against the pipeline to be bent.

[0026] Seen in Figure 2 The clamping part 110 also includes a clamping slider 213. The clamping block seat 211 is fixedly disposed on the top of the clamping slider 213 near the mating part 101. The top of the clamping slider 213 is also provided with a support seat 214. The support seat 214 is provided with a retractable top rod 215, which is used to abut against the clamping block seat 211.

[0027] Specifically, by abutting the top rod 215 against the clamping block seat 211, the support seat 214 can be prevented from loosening when the rotating arm 100 rotates to squeeze the pipeline, which would cause the serpentine clamping block 212 to loosen, thus reducing the processing quality and efficiency of the serpentine pipeline.

[0028] Seen in Figure 1-4 The drive unit 120 includes a drive cylinder 221 rotatably disposed in the mating cavity, and a connecting rod assembly that drives the clamping slider 213 at the bottom. The drive cylinder 221 is used to drive the connecting rod assembly to raise and lower the clamping slider 213. The drive cylinder 221 has a piston rod 2211, and the end of the piston rod 2211 is provided with a connector 3212, which is used to mate with the connecting rod assembly.

[0029] The linkage assembly includes a first pin 351 and a second pin 352 spaced apart below the clamping slider 213. The first pin 351 and the second pin 352 are at the same height and are rotatably engaged with both sides of the bearing part 102. The bottom of the clamping slider 213 is provided with a first mounting seat 4131 and a second mounting seat 4132 spaced apart. A third pin 353 is provided at the first mounting seat 4131 and a fourth pin 354 is provided at the second mounting seat 4132. A first connecting rod 355 is provided on both sides of the first mounting seat 4131. The first connecting rod 355 is used to rotatably engage with the first pin 351 and the third pin 353. A second connecting rod 356 is provided in the middle of the second mounting seat 4132. The second connecting rod 356 is used to rotatably engage with the second pin 352 and the fourth pin 354.

[0030] Furthermore, a third mounting base 4213 is provided at the joint 3212, a fifth pin 357 is provided at the third mounting base 4213, a third connecting rod 358 is provided in the middle of the third mounting base 4213, the third connecting rod 358 is used to rotate with the third pin 353 and the fifth pin 357, and a fourth connecting rod 359 is provided on both sides of the third mounting base 4213, the fourth connecting rod 359 is used to rotate with the first pin 351 and the fifth pin 357.

[0031] Specifically, when the piston rod 2211 extends out of the drive cylinder 221, that is, when the piston rod 2211 is in the pushing stroke, the angle of the third connecting rod 358 and the fourth connecting rod 359 increases, thereby increasing the distance between the second pin 352 and the third pin 353. The lengths of the first connecting rod 355 and the second connecting rod 356 are the same, so the clamping slider 213 is always in a horizontal state. Therefore, when the piston rod 2211 is in the pushing stroke, the clamping slider 213 rises, and at this time the serpentine clamping block 212 clamps the pipeline. Conversely, when the piston rod 2211 is in the return stroke, the clamping slider 213 falls, and at this time the serpentine clamping block 212 releases the pipeline.

[0032] Seen in Figure 2The material support section includes two support rods 230, which are rotatably engaged with the first pin 351 and the second pin 352 respectively. A material support plate 231 is provided on one side of each of the two support rods 230, and the material support plate 231 is rotatably engaged with the two support rods 230. At least one fourth mounting seat 241 is provided at the end of the clamping slider 213 away from the clamping block seat 211. An optical axis 242 is provided at the fourth mounting seat 241, and a fifth connecting rod 243 is provided at one end of the optical axis 242. The fifth connecting rod 243 is used to rotatably engage with the optical axis 242 and any one of the support rods 230.

[0033] Specifically, the fifth link 243 of the material support plate 231 enables the two support rods 230 to be raised and lowered simultaneously with the clamping slider 213, thereby facilitating the support of the bent serpentine pipe during the bending process. Furthermore, when the serpentine clamping block 212 releases the pipe after bending, the height of the pipe is simultaneously reduced to facilitate the user in removing the bent serpentine pipe.

[0034] Seen in Figure 5 The support rod 230 includes a lower adjusting bolt 531 and an upper adjusting bolt 532 arranged coaxially. An adjusting nut 533 is provided between the lower adjusting bolt 531 and the upper adjusting bolt 532. The adjusting nut 533 is used to adjust the relative distance between the lower adjusting bolt 531 and the upper adjusting bolt 532. A round nut 534 is provided at the lower adjusting bolt 531. The round nut 534 is used to abut against the adjusting bolt.

[0035] Specifically, by having the upper adjusting bolt 532 and the lower adjusting bolt 531 cooperate with the adjusting nut 533 respectively, the relative distance between the upper adjusting nut 533 and the lower adjusting nut 533 can be adjusted, thereby better adjusting the height of the material support plate 231 to adapt to serpentine pipelines of different diameters.

[0036] Working principle:

[0037] When using the auxiliary material support mechanism of this serpentine pipe bending machine, first start the feeding mechanism of the bending machine to transport the pipe to be bent to the bending die. Then, drive the hydraulic cylinder 221 to drive the clamping slider 213 to rise, so that the clamping surface 2121 of the serpentine clamping block 212 abuts against the pipe to be bent. At this time, the material support plate 231 is raised at the same time. Then, the rotating arm 100 rotates to feed the material in conjunction with the feeding mechanism, which can continuously bend the serpentine pipe. The stripper plate can support the bent serpentine pipe, thereby avoiding the serpentine pipe from being suspended and twisted, thus reducing the quality of the finished product.
