Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe grooving machines, and particularly to an automatic steel pipe grooving machine. Background Technique

[0002] With the rapid development of modern industrial technology, various industrial equipment plays a crucial role in the production process. Among them, the grooving machine, as a key equipment specifically used for pressing grooves on materials such as steel plates and steel pipes, its application fields have covered multiple industries such as pipeline engineering, mechanical manufacturing, and architectural decoration. In actual production, to ensure the accuracy of grooving processing, it is necessary to achieve stable clamping and precise alignment of the steel pipe on the grooving machine through a positioning mechanism, which is not only the basis for ensuring processing quality, but also an important link for improving production efficiency and ensuring operation safety.

[0003] However, the positioning mechanisms of traditional grooving machines generally have the defect of insufficient adaptability. Their structural designs are often limited to steel pipes of specific specifications. When facing steel pipes of different diameters, it is usually necessary to frequently replace fixtures or perform complex manual adjustments, which not only seriously affects production efficiency, but also is difficult to meet the needs of diversified processing. Therefore, we propose a new type of automatic steel pipe grooving machine. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic steel pipe grooving machine, which can effectively solve the problems raised in the background technique.

[0005] To achieve the above object, the present invention provides the following technical solution: An automatic steel pipe grooving machine, including a base, one end of the top of the base is fixedly installed with a fixed bracket, and the other end of the top of the base is slidably connected with a slidable bracket. Steel pipe end fixing structures are fixedly installed on both the fixed bracket and the slidable bracket.

[0006] The steel pipe end fixing structure includes hollow base columns fixedly installed on the fixed bracket and the slidable bracket. A number of rubber air bags are fixedly installed on the hollow base columns. The rubber air bags are connected by a number of short pipes. A number of long pipes are fixedly installed on one of the rubber air bags. The intake end of the long pipe is provided with a multi-fork pipe. The outlet end of the multi-fork pipe is fixedly connected and communicated with the intake end of the long pipe. The intake end of the multi-fork pipe is fixedly connected with a one-way valve, and the intake end of the one-way valve is fixedly installed with an external conduit.

[0007] Preferably, an exhaust pipe with an electric valve, which is communicated with the inner cavity of the rubber air bag, is fixedly installed on the inner circular surface of the rubber air bag, and the exhaust pipe with the electric valve penetrates through the hollow base column.

[0008] Preferably, the rubber air bag and the hollow base column are on the same axis, and a number of the rubber air bags are linearly distributed on the hollow base column.

[0009] Preferably, one end of the hollow foundation column is open, and the other end is closed; the hollow foundation columns on the fixed bracket and the slidable bracket both penetrate through the fixed bracket and the slidable bracket.

[0010] Preferably, the long pipes are installed on the rubber air bags close to the fixed bracket and the slidable bracket, and the long pipes both penetrate through the fixed bracket and the slidable bracket.

[0011] Preferably, slide rails are symmetrically installed on the top of the base, sliders are slidably connected in the inner cavities of the slide rails, a gantry is fixedly installed on the sliders, an electric telescopic rod is fixedly installed on the gantry, and a pressing block is fixedly installed at the output end of the electric telescopic rod.

[0012] Preferably, the structures of the fixed bracket and the slidable bracket are inconsistent; the slidable bracket is composed of an arched seat and two T-shaped blocks; a chute adapted to the T-shaped blocks is opened inside the base; the fixed bracket is composed of an arched seat alone.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting the fixed structure of the slidable bracket and the adaptive rubber air bag, the limitation of the traditional grooving machine on the steel pipe specification is broken through. The rubber air bag expands by inflation and closely adheres to the inner wall of steel pipes with different diameters. Combined with the flexible adjustment of the slidable bracket, there is no need to replace the fixture or manually adjust frequently, which significantly improves the equipment adaptability, meets the diversified processing requirements, and effectively solves the problems of low efficiency and cumbersome operation of the traditional equipment.

[0015] 2. Through the collaborative design of the slide rail, the slider and the electric telescopic rod, the precise movement of the gantry and the rapid positioning of the grooving position are realized. The operator can freely adjust the position of the pressing block along the axial direction of the steel pipe, avoiding the steps of manually fixing the steel pipe repeatedly, reducing the processing interruption time. At the same time, through the stable downward pressure of the electric telescopic rod, the grooving depth is ensured to be uniform, taking into account both production efficiency and processing accuracy.

[0016] 3. By adopting the rubber air bag fixation and the exhaust pipe with an electric valve, a buffer protection mechanism is formed during the grooving process. The radial uniform expansion of the rubber air bag offsets the mechanical impact force, preventing local deformation of the steel pipe end caused by rigid clamping; combined with the rapid exhaust function, the air bag pressure can be quickly released, simplifying the steel pipe disassembly process, further shortening the operation cycle, and overall improving the equipment safety and operation convenience.

Detailed implementation manners

[0024] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are generally in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for ease of understanding and description, "left, right" are generally left and right as shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms are not used to limit the present invention.

[0025] The present invention provides a technical solution:

[0026] Please refer to Figures 1 to 5 , a steel pipe automatic grooving machine, characterized in that it includes a base 1, a fixed bracket 2 is fixedly installed at one end of the top of the base 1, a slidable bracket 3 is slidably connected to the other end of the top of the base 1, and a steel pipe end fixing structure 4 is fixedly installed on both the fixed bracket 2 and the slidable bracket 3.

[0027] The steel pipe end fixing structure 4 includes a hollow foundation column 401 fixedly installed on the fixed bracket 2 and the slidable bracket 3, a plurality of rubber airbags 402 are fixedly installed on the hollow foundation column 401, a plurality of short pipes 403 are used to connect the rubber airbags 402, a plurality of long pipes 404 are fixedly installed on one of the rubber airbags 402, a multi-fork pipe 405 is arranged at the air inlet end of the long pipe 404, the air outlet end of the multi-fork pipe 405 is fixedly connected and communicated with the air inlet end of the long pipe 404, a one-way valve 406 is fixedly connected to the air inlet end of the multi-fork pipe 405, and an external conduit 407 is fixedly installed at the air inlet end of the one-way valve 406.

[0028] The steel pipe end fixing structure 4 is fixed on the fixed bracket 2 and the sliding bracket 3 through the hollow foundation column 401. An external inflating device is connected by an external conduit 407. Gas enters the rubber airbag 402 near the bracket through a one-way valve 406, a multi-fork pipe 405, and a long pipe 404, and then fills other rubber airbags 402 through a short pipe 403, causing them to expand and tightly adhere to the inner wall of the steel pipe to complete the fixation. This structure realizes the universal fixation of steel pipes with different diameters through the inflation and expansion of the rubber airbag 402, overcomes the disadvantage of insufficient adaptability of traditional grooving machines, improves production efficiency and processing quality. At the same time, the design of its one-way valve 406 ensures the unidirectionality of the inflation process, avoids gas leakage, and enhances the stability of the fixation.

[0029] Please refer Figures 3 to 5 , an exhaust pipe 408 with an electric valve, which is communicated with the inner cavity of the rubber airbag 402, is fixedly installed on the inner circular surface of the rubber airbag 402. The exhaust pipe 408 with an electric valve penetrates through the hollow foundation column 401.

[0030] After the grooving operation of the steel pipe is completed, by opening the exhaust pipe 408 with an electric valve installed on the inner circular surface of the rubber airbag 402, the gas in the rubber airbag 402 is released and discharged through the exhaust pipe penetrating the hollow foundation column 401, causing the rubber airbag 402 to contract, so as to facilitate the removal of the grooved steel pipe from the steel pipe. This design simplifies the disassembly process of the steel pipe through the rapid exhaust function, reduces the operation interruption time, improves production efficiency. At the same time, the setting of the exhaust pipe 408 with an electric valve ensures the controllability of the exhaust process, enhances the safety of the equipment and improves the operation convenience, effectively solving the problem of difficult disassembly caused by rigid fixation of traditional grooving machines.

[0031] In some embodiments, the rubber airbag 402 and the hollow foundation column 401 are on the same axis line, and several rubber airbags 402 are linearly distributed on the hollow foundation column 401.

[0032] In this embodiment, when the steel pipe automatic grooving machine is working, an external inflating device inflates the rubber airbag 402 near the fixed bracket 2 and the sliding bracket 3 through an external conduit 407, a one-way valve 406, a multi-fork pipe 405, and a long pipe 404, and the gas is then transmitted to the remaining rubber airbags 402 through a short pipe 403. Since the rubber airbag 402 and the hollow foundation column 401 are coaxial and linearly distributed, all the rubber airbags 402 can expand synchronously and evenly, tightly adhering to the inner wall of the steel pipe. This design ensures that the steel pipe receives uniform clamping force during the grooving process, avoids processing errors caused by uneven clamping, improves the adaptability of the equipment to steel pipes with different diameters, and enhances the stability of the fixation and the processing accuracy.

[0033] In some embodiments, one end of the hollow foundation column 401 is open, and the other end of the hollow foundation column 401 is closed; the hollow foundation columns 401 on the fixed bracket 2 and the slidable bracket 3 both penetrate the fixed bracket 2 and the slidable bracket 3.

[0034] In this embodiment, the gas in the rubber airbag 402 is discharged through the open end of the hollow foundation column 401 to facilitate the disassembly of the steel pipe, and the closed end provides structural support. The design of penetrating the fixed bracket 2 and the sliding bracket 3 enhances the stability of the overall structure, effectively solving the problems of difficult disassembly and insufficient adaptability of traditional grooving machines due to rigid fixation.

[0035] In some embodiments, the long tube 404 is installed on the rubber airbag 402 close to the fixed bracket 2 and the slidable bracket 3 , wherein the long tube 404 passes through the fixed bracket 2 and the slidable bracket 3 .

[0036] In this embodiment, when the automatic steel pipe grooving machine is operating, the external inflation device is connected to the multi-branch tube 405 through the external conduit 407. After the gas enters the multi-branch tube 405 through the one-way valve 406, it is distributed to the long tube 404. Since the long tube 404 is installed on the rubber airbags 402 close to the fixed bracket 2 and the sliding bracket 3 and passes through the bracket, the gas is directly filled into these rubber airbags 402 and then transmitted to other airbags through the short tube 403 to achieve synchronous expansion; this design ensures that the gas quickly and evenly fills all rubber airbags 402, thereby improving the inflation efficiency.

[0037] See also Figures 1 to 2 The top of the base 1 is symmetrically installed with a slide rail, the inner cavity of the slide rail is slidably connected with a slider 5, the slider 5 is fixedly installed with a gantry 6, the gantry 6 is fixedly installed with an electric telescopic rod 7, and the output end of the electric telescopic rod 7 is fixedly installed with a pressure block 8.

[0038] During the operation of the automatic grooving machine for steel pipes, the slider 5 slidingly connected to the slide rail on the top of the base 1 drives the gantry 6 to move along the axial direction of the steel pipe, and is positioned to the target grooving position through a manual or automatic control system. Then the electric telescopic rod 7 on the gantry 6 drives the pressing block 8 to descend smoothly to accurately groove the fixed steel pipe. This design realizes the rapid positioning and adjustment of the grooving position, reduces the steps of repeated manual fixing of the steel pipe, and significantly improves the processing efficiency and accuracy. At the same time, the stable downward pressure of the electric telescopic rod 7 ensures that the grooving depth is uniform and consistent, thereby enhancing the degree of automation and ease of operation of the equipment.

[0039] In some embodiments, the structures of the fixed bracket 2 and the slidable bracket 3 are inconsistent; the slidable bracket 3 is composed of an arch seat and two T-blocks; a sliding groove adapted to the T-block is opened inside the base 1; the fixed bracket 2 is composed of the arch seat alone.

[0040] In this embodiment, the fixed bracket 2 is composed of an arched seat alone, providing a stable support foundation; the slidable bracket 3 is combined with two T-shaped blocks through the arched seat, and the T-shaped blocks are embedded in the matching chute opened inside the base 1 to achieve flexible sliding along the axial direction of the steel pipe, so as to adapt to the fixing requirements of steel pipes of different lengths; this design, through the fixed bracket 2 and the slidable bracket 3 with different structures, not only ensures the stable fixation of one end of the steel pipe, but also realizes the function of flexibly adjusting the position of the other end according to the length of the steel pipe, enhancing the versatility and adaptability of the equipment, and effectively solving the problem of insufficient adaptability of traditional grooving machines to the length of steel pipes.

[0041] During specific use, the working principle of the present invention is as follows:

[0042] First, the operator slides the slidable bracket 3 to an appropriate position according to the length of the steel pipe to be processed, and inserts one end of the steel pipe smoothly into the hollow base column 401 on the fixed bracket 2. Subsequently, continue to adjust the slidable bracket 3 to ensure that the hollow base column 401 thereon can be completely and accurately inserted into the other end of the steel pipe, and the hollow base column 401 needs to penetrate deep into the steel pipe completely to ensure the stability of subsequent fixation.

[0043] After both ends of the steel pipe are in place, the operator manually fixes the position of the slidable bracket 3 to prevent it from shifting. Next, use an external inflation device to inflate the steel pipe end fixing structure 4. The specific operation is to firmly connect the inflation end of the external inflation device to the external catheter 407, and then start the inflation device. The gas first enters the multi-fork pipe 405 through the external catheter 407, and then is distributed from the multi-fork pipe 405 to each long pipe 404, and then is filled into the rubber air bags 402 near the fixed bracket 2 and the slidable bracket 3. As these rubber air bags 402 expand, the gas is transmitted to the remaining rubber air bags 402 through the short pipes 403, so that all the rubber air bags 402 expand synchronously and tightly fit the inner wall of the steel pipe, thereby realizing the effective fixation of steel pipes of different diameters.

[0044] After the steel pipe is fixed, start the electric telescopic rod 7, and the electric telescopic rod 7 drives the pressing block 8 to descend smoothly to perform precise grooving operation on the steel pipe. During the grooving process, to ensure the processing accuracy, it is necessary to manually maintain the stability of the gantry 6 to prevent it from sliding. If it is necessary to groove different positions of the steel pipe, the operator can easily move the gantry 6 above the target position through the cooperation of the slider 5 and the slide rail, and continue to perform the grooving operation.

[0045] After the grooving operation is completed, control the exhaust pipe 408 with an electric valve to open, and the gas in the rubber air bag 402 is released, and the gas is discharged from the open end of the hollow base column 401, which is convenient for the operator to easily remove the grooved steel pipe.

[0046] In addition, the device uses a rubber airbag 402 as a fixing element at the end of the steel pipe. Compared with the traditional rigid fixing method, the rubber airbag 402 can provide a good buffering effect during the grooving process, effectively avoiding deformation of the end of the steel pipe due to pressure concentration, thus ensuring the processing quality and the integrity of the steel pipe.

[0047] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
