[0001] This utility model belongs to the field of double-wall corrugated pipe flaring technology, and particularly relates to a double-wall corrugated pipe flaring machine. Background Technology

[0002] Existing double-wall corrugated pipes are a new type of lightweight pipe made of high-density polyethylene. They are characterized by light weight, high pressure resistance, good toughness, fast construction and long service life. Their excellent pipe wall structure design greatly reduces costs compared with other pipe structures, and they are widely used at home and abroad, replacing a large number of concrete pipes and cast iron pipes.

[0003] During the flaring process of double-wall corrugated pipes, in order to achieve uniform flaring, the double-wall corrugated pipes need to be rotated manually multiple times, which results in low work efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the process of flaring double-wall corrugated pipes, in order to achieve uniform flaring, the double-wall corrugated pipes need to be rotated manually multiple times, resulting in low work efficiency.

[0006] Furthermore, the positioning assembly includes a fixing plate, an electric push rod, and a clamping plate, wherein:

[0007] The fixing plate is fixedly connected to the top of the base. The electric push rod passes horizontally through the fixing plate and is fixedly connected to it. The clamping plate is fixedly connected to the free end of the electric push rod. The top of the base is provided with a bottom groove. There are at least two sets of bottom grooves. The radius of the bottom groove increases from the inside to the outside. The double-wall corrugated pipe body is inserted into the bottom groove. The outer wall of the clamping plate is in contact with the outer wall of the double-wall corrugated pipe body.

[0008] Furthermore, the positioning component also includes an insert block and an inner ring, wherein:

[0009] The base has slots on top, which are symmetrically distributed in pairs. The insert is inserted into the slot, and the inner ring is fixedly connected to the top of the insert. The outer wall of the inner ring is in contact with the inner wall of the double-wall corrugated pipe body.

[0010] Furthermore, the flaring assembly includes a hydraulic rod, a connecting plate, a guide rod, a threaded block, and a flaring disc, wherein:

[0011] The hydraulic rod passes vertically through the fixed frame and is fixedly connected to it. The connecting plate is fixedly connected to the free end of the hydraulic rod. The guide rod passes vertically through the connecting plate and is slidably connected to it. The flared plate is fixedly connected to the lower end of the guide rod. The threaded block is threadedly connected to the guide rod and is located below the connecting plate.

[0012] Furthermore, the flaring assembly also includes a base plate, a servo motor, a disk, and a movable rod, wherein:

[0015] The beneficial effects of this utility model after adopting the above structure are as follows:

[0016] (1) The double-wall corrugated pipe body can be inserted into the corresponding bottom groove, and then the inner ring can be inserted into the slot through the insert block. The electric push rod can be extended to clamp the clamp plate on the outer wall of the double-wall corrugated pipe body, so that the double-wall corrugated pipe body can be stably placed and positioned.

[0017] (2) The extension of the hydraulic rod allows the flaring disc to flare the top of the double-walled corrugated pipe body, and the uniform rotation of the disc causes the movable rod to drive the flaring disc to move up and down repeatedly, applying pressure to the flaring area to ensure the flaring effect.

[0018] (3) The whole system can quickly complete the placement and positioning of the double-wall corrugated pipe body and can efficiently expand its port. This solves the problem of manually rotating and expanding the double-wall corrugated pipe multiple times to ensure uniform expansion, thus improving work efficiency. Attached Figure Description

The fixing frame 2 is fixedly connected to the top of the base 1, and the double-wall corrugated pipe body 3 is located on the top of the base 1. It also includes a positioning component and a flaring component. The positioning component is located on the top of the base 1 and is symmetrically distributed. The flaring component is located on the fixing frame 2.

[0027] The double-wall corrugated pipe body 3 is clamped and positioned by the positioning component, and the double-wall corrugated pipe body 3 is efficiently flared by the flaring component.

[0028] like Figure 1-5 As shown, in order to quickly place and position the double-wall corrugated pipe body 3, the positioning assembly includes a fixing plate 4, an electric push rod 5, a clamping plate 6, an insert block 8, and an inner ring 9. The fixing plate 4 is fixedly connected to the top of the base 1. The electric push rod 5 passes horizontally through the fixing plate 4 and is fixedly connected to it. The clamping plate 6 is fixedly connected to the free end of the electric push rod 5. The outer wall of the clamping plate 6 is symmetrically bent and can be used to clamp double-wall corrugated pipe bodies 3 of different diameters. The top of the base 1 is provided with a bottom groove 7. There are at least two sets of bottom grooves 7. The radius of the bottom groove 7 increases from the inside to the outside. The double-wall corrugated pipe body 3 is inserted into the bottom groove 7. The outer wall of the clamping plate 6 is in contact with the outer wall of the double-wall corrugated pipe body 3. The top of the base 1 is provided with a slot 10. The slots 10 are symmetrically distributed in pairs. The insert block 8 is inserted into the slot 10. The inner ring 9 is fixedly connected to the top of the insert block 8. The outer wall of the inner ring 9 is in contact with the inner wall of the double-wall corrugated pipe body 3.

[0029] like Figure 1-5As shown, to efficiently complete the flaring operation of the double-walled corrugated pipe body 3, the flaring assembly includes a hydraulic rod 11, a connecting plate 12, a guide rod 13, a threaded block 14, a flaring disc 15, a base plate 16, a servo motor 17, a disc 18, and a movable rod 19. The hydraulic rod 11 vertically penetrates the fixed frame 2 and is fixedly connected to it. The connecting plate 12 is fixedly connected to the free end of the hydraulic rod 11. The guide rod 13 vertically penetrates the connecting plate 12 and is slidably connected to it. The guide rod 13 is T-shaped. The flaring disc 15... A threaded block 14 is threadedly connected to the guide rod 13 at the lower end and is located below the connecting plate 12. A base plate 16 is fixedly connected to the bottom of the connecting plate 12. A servo motor 17 is fixedly installed on the outer wall of the base plate 16. A disc 18 is fixedly connected to the output end of the servo motor 17. The two ends of the movable rod 19 are rotatably connected between the top of the flared plate 15 and the outer wall of the disc 18. The movable rod 19 and the disc 18 are eccentrically connected. The diameter of the outer wall of the flared plate 15 increases from bottom to top.

[0030] In practical use, the double-wall corrugated pipe body 3 is inserted into the corresponding bottom groove 7, and then the inner ring 9 is inserted into the slot 10 through the insert block 8. The electric push rod 5 is extended to clamp the clamping plate 6 onto the outer wall of the double-wall corrugated pipe body 3, thus completing the placement and positioning of the double-wall corrugated pipe body 3. Then, the threaded block 14 is screwed to make it fit tightly against the bottom wall of the connecting plate 12. The hydraulic rod 11 is extended at a uniform speed to make the flaring plate 15 flare the top of the double-wall corrugated pipe body 3. The threaded block 14 fits tightly against the bottom wall of the connecting plate 12. To avoid affecting the movable rod 19 when the flaring plate 15 moves downward, and to increase the downward stability of the flaring plate 15, the hydraulic rod 11 is then controlled to retract a suitable distance before the threaded block 14 is screwed away from the bottom of the connecting plate 12. Then, the servo motor 17 is turned on, and the uniform rotation of the disc 18 causes the movable rod 19 to drive the flaring plate 15 to move up and down repeatedly, applying repeated pressure to the flaring area to ensure the flaring effect. During the process, the flaring plate 15 drives the guide rod 13 to slide on the connecting plate 12, increasing the stability of the flaring plate 15.
