Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and in particular to a pipe side hole flanging device. Background Technology

[0002] When pipe fittings are used as manifolds or to connect different branch lines, side holes need to be drilled and flanged on the fitting's circumferential wall. Currently, the side holes obtained through machining are usually only straight holes. Straight hole structures require high precision from the external connecting pipe during assembly and welding. The connecting pipe must precisely match the inner or outer diameter of the side hole to ensure it is securely inserted before machining. Otherwise, clamping fixtures need to be designed to fix both the connecting pipe and the fitting separately, increasing the welding and assembly process and production costs.

[0003] Current pipe fitting side hole flanging devices can only produce straight hole structures in a single processing step, placing high demands on subsequent pipe fitting production. Therefore, there is still room for improvement in the current pipe fitting side hole flanging structure. Summary of the Invention

[0008] A rotating platform, wherein the rotating platform is disposed on the lifting platform;

[0009] The cutter head mechanism includes a first telescopic driver, an open sleeve, a flaring member, and a flaring structure. The open sleeve is mounted on a rotary table and has a slit. The first telescopic driver includes a first telescopic seat mounted on the rotary table and a first telescopic rod that extends and retracts along the first telescopic seat. The first telescopic rod is driven to connect with the flaring member. When the flaring member retracts under the drive of the first telescopic rod, it expands the maximum outer diameter of the open sleeve. The end of the flaring member away from the first telescopic seat is an outward-flared end, and the outward-flared end can expand its outer diameter through the flaring structure.

[0010] The beneficial effects of the present invention are as follows: In addition to expanding the opening sleeve by the first telescopic driver and the flaring member to flare the pre-processed side hole on the pipe fitting, the pipe fitting side hole flaring device also expands the outward flaring end of the flaring member by the flaring structure, and makes the flaring outward flaring by the rotation of the flaring member driven by the lifting platform, so as to simplify the subsequent processing of the pipe fitting.

The flaring mounting platform has a clearance hole in the middle to avoid the drive column. The flaring mounting platform has a first sliding groove and a second sliding groove along the transverse direction.

[0012] The flaring component includes a first flaring arm and a second flaring arm. The first flaring arm is provided with a first sliding arm that slides along the first sliding groove, and the second flaring arm is provided with a second sliding arm that slides along the second sliding groove.

[0032] The following is combined Figures 1 to 3 Embodiments of the present invention will be described.

[0033] This embodiment relates to a pipe fitting side hole flanging device, which can not only flanging side holes on pipe fittings, but also flaring or outward turning of the flanging for subsequent pipe fitting processing and production.

[0034] The pipe fitting side hole flanging device of this embodiment includes:

[0035] Frame (not shown in the figure), lifting platform 1, rotary table 2, cutter head mechanism;

[0036] The lifting platform 1 is rotatably mounted on the frame;

[0037] The rotary table 2 is mounted on the lifting platform 1;

[0038] The cutting head mechanism includes a first telescopic driver 31, an opening sleeve 32, a flaring member 33, and a flaring structure. The opening sleeve 32 is mounted on a rotary table 2 and has a slit. The first telescopic driver 31 includes a first telescopic seat 311 mounted on the rotary table 2 and a first telescopic rod 312 that extends and retracts along the first telescopic seat 311. The first telescopic rod 312 is driven to connect with the flaring member 33. When the flaring member 33 is retracted by the first telescopic rod 312, it expands the maximum outer diameter of the opening sleeve 32. The end of the flaring member 33 away from the first telescopic seat 311 is an outward-flared end, and the outward-flared end can expand its outer diameter through the flaring structure.

[0039] When using this pipe fitting side hole flanging device, firstly, a side hole is pre-drilled on the pipe fitting. Then, the pipe fitting is moved so that the flared part 33 is aligned with the side hole. Next, the lifting platform 1 descends, allowing the flared part 33 to pass through the side hole and extend into the pipe fitting. The first telescopic rod 312 actuates, expanding the maximum outer diameter of the opening sleeve 32 through the flared part 33. Then, the lifting platform 1 rises, driving the opening sleeve 32 through the side hole, thus flanging the side hole. Furthermore, since this pipe fitting side hole flanging device is equipped with a rotary table 2, the opening sleeve 32 can be rotated during the lifting process of the lifting platform 1, improving the machining accuracy of the side hole. After the opening sleeve 32 has completely left the side hole, the first flanging of the side hole is completed, resulting in the first flanging. Then, the first telescopic actuator 31 drives the flared part 33 to extend, and the flaring structure enlarges the maximum outer diameter of the outward-facing end of the flared part 33. The lifting platform 1 descends until the outward-facing end of the flared part 33 abuts against the top side of the first flange. Then, the rotary table 2 starts and the lifting platform 1 descends simultaneously, which enables the first flange to be folded again to obtain a second flange, thus realizing two flanges on the side hole of the pipe fitting. The second flange can form a flared structure on the side hole so that the connecting pipe can be inserted into the side hole along the flare for welding.

[0040] Specifically, the flaring structure includes a second telescopic actuator 342, a flaring mounting platform 341, and a drive column 343. The second telescopic actuator 342 is mounted on the first telescopic rod 312 and is drivenly connected to the drive column 343. The first telescopic rod 312 is drivenly connected to the flaring mounting platform 341. The flaring mounting platform 341 has a clearance hole in its middle to avoid the drive column 343. The flaring mounting platform 341 has a first sliding groove 3411 and a second sliding groove 3412 along the transverse direction. The opening member 33 includes a first flaring arm 331 and a second flaring arm 332. The first flaring arm 331 is provided with a first sliding arm 351 that slides along the first sliding groove 3411. The second flaring arm 332 is provided with a second sliding arm that slides along the second sliding groove 3412. The top surface of the first flaring arm 331 is provided with a first inclined surface 3311 facing the second sliding arm. The driving column 343 is driven by the second telescopic driver 342 to abut against the first inclined surface 3311 and push open the first flaring arm 331 and the second flaring arm 332.

[0041] The flaring structure allows the flared member 33 to switch between an inward-retracting state and an outward-expanding state. In the inward-retracting state, the first flaring arm 331 and the second flaring arm 332 of the flared member 33 can expand outward, thereby increasing the outer diameter of the outward-flared end to be larger than the side hole after flanging. The side hole is then flanged a second time by abutting against the side hole after flanging. Specifically, in the inward-retracting state, the opposing surfaces of the first flaring arm 331 and the second flaring arm 332 remain in contact, minimizing the distance between them. Lifting the opening sleeve 32 in the inward-retracting state ensures that the structure of the flared member 33 remains consistent each time the opening sleeve 32 is lifted. When switching from the inward-retracting state to the outward-expanding state, the second telescopic actuator 342 drives the drive column 343 to push open the first flaring arm 331 and the second flaring arm 332 from the first inclined surface 3311, thus switching the flared member 33 to the outward-expanding state. In the expanded state, the expansion range can be adjusted by controlling the insertion depth of the drive column 343, thereby adjusting the shape of the second flange. The simplified structural design of this flaring structure and the flaring component 33 enables the first and second flanges of the side hole to be achieved on the pipe fitting side hole flange device.

[0042] To ensure the first flaring arm 331 slides stably along the first slide groove 3411, the first slide arm 351 includes a first sliding plate 3512 and a first sliding column 3511. The first sliding column 3511 extends into the first slide groove 3411, and the first sliding plate 3512 abuts against the top surface of the flaring mounting platform 341. The first sliding plate 3512 is connected to the first flaring arm 331 via the first sliding column 3511. The bottom surface of the first sliding plate 3512 abuts against the top surface of the flaring mounting platform 341, causing the first sliding column 3511 to hang on the flaring mounting platform 341. This prevents the first flaring arm 331 from falling out during sliding and ensures that the first flaring arm 331 can reliably move with the lifting platform 1 and the rotating platform 2.

[0043] To ensure greater stability of the first flaring arm 331 and the second flaring arm 332 in the retracted state, the flaring structure further includes a first spring 36. The first spring 36 is located within the first sliding groove 3411. One end of the first spring 36 abuts against the side of the first sliding groove 3411 away from the second flaring arm 332, and the other end abuts against the first sliding post 3511. Thus, the first spring 36 can fix the position of the first sliding post 3511, i.e., the first flaring arm 331, thereby ensuring stability of the first flaring arm 331 and the second flaring arm 332 in the retracted state.

[0044] Furthermore, the flaring structure includes a second spring 37, which is located between the second slide groove 3412 and the second flaring arm 332, driving the second flaring arm 332 to move towards the first flaring arm 331. Similarly, the second spring 37 allows the position of the second flaring arm 332 to be fixed, thus ensuring stability of the first flaring arm 331 and the second flaring arm 332 in the retracted state. In this embodiment, under the force of the first spring 36 and the second spring 37, the first flaring arm 331 and the second flaring arm 332 are respectively restricted by the end faces of the first slide groove 3411 and the second slide groove 3412, keeping their positions fixed.

[0045] The lower end of the first flared arm 331 is provided with a first flanged inclined surface 3312. Providing the lower end of the first flared arm 331 with the first flanged inclined surface 3312 helps to improve the stability of the flange of the first flared arm 331.

[0046] The drive column 343 is detachably connected to the second telescopic actuator 342. The detachable structure of the drive column 343 and the second telescopic actuator 342 allows the drive column 343 to be replaced as needed to obtain the desired shape after the second flanging.

[0047] Furthermore, the top surface of the second flared arm 332 facing the second sliding arm is provided with a second inclined surface 3321. The drive column 343, driven by the second telescopic actuator 342, abuts against the first inclined surface 3311 and the second inclined surface 3321, and pushes open the first flared arm 331 and the second flared arm 332. Similarly, the second inclined surface 3321 on the second flared arm 332 ensures that the force exerted by the drive column 343 on the first flared arm 331 and the second flared arm 332 is distributed more evenly on both, which helps to improve the service life of the first flared arm 331 and the second flared arm 332.

[0048] The lower end of the second flared arm 332 is also provided with a second flanged inclined surface 3322. The second flanged inclined surface 3322 enables the second flared arm 332 to also perform a secondary flange on the side hole, ensuring that the first flared arm 331 and the second flared arm 332 are subjected to equal forces.

[0049] The lower end of the drive column 343 is provided with a drive cone surface 3431. The drive cone surface 3431 on the drive column 343 can increase the contact area when the drive column 343 contacts the first flared arm 331 and the second flared arm 332, thereby reducing the force on the drive column 343.

[0050] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
