Description

Technical Field

[0001] The present invention belongs to the field of machining, and more specifically, relates to a blanking device for pipes, and the present invention also relates to a pipe production line. Background Art

[0002] Pipes are materials used for making pipe fittings. Different pipe fittings require different pipes, and the quality of the pipes directly determines the quality of the pipe fittings. Such pipes are widely used in construction projects, power plants, chemical plants, etc.

[0003] Among them, the pipes that are more widely used are generally rolled from steel strips. First, the steel strip is unrolled by an uncoiling device, and then is pulled by a traction wheel to a rolling mill. During the rolling process of multiple rolling mills, the steel strip is extruded into a preset cross-sectional shape. After the steel strip is rolled by the rolling mill, it sequentially enters the downstream welding and deburring stations to weld the joints of the pipes and remove burrs. After the above operations are completed, the pipes can be cut into required specifications.

[0004] After the pipes are cut, the smaller-sized pipes need to be bundled and packed. Multiple pipes are shaped into regular polygons and then tied tightly to facilitate the storage and transportation of the pipes. The larger-sized pipes are transported individually after removing the burrs at the ports.

[0005] The inventor found in the actual production process that for the existing larger-sized pipes, during subsequent assembly or on-site processing, it is necessary to chamfer the port parts of the pipes, which not only makes the length of the pipes more accurate but also facilitates the subsequent welding of the pipes. However, due to reasons such as the limitations of production equipment, the existing equipment cannot chamfer the port parts of the pipes during the cutting operation of the pipes, which has an adverse impact on the processing efficiency of the pipes and urgently needs to be improved. Summary of the Invention

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please refer to Figure 1 and Figure 2 together, and now a pipe blanking device provided by the present invention will be described. The pipe blanking device includes a cutting mechanism, a shaping mechanism and a supporting mechanism. The cutting mechanism includes a rotatable cutting disc 11, and the cutting disc 11 is used to perform radial cutting on the pipe. The cutting disc 11 is movably arranged on one side of the pipe along a direction perpendicular to its own axis; the shaping mechanism includes a scraper 12 arranged on the cutting disc 11. The scraper 12 includes a tool handle 121 and a tool head 122. The tool handle 121 is telescopically arranged on the cutting disc 11 along its own axis, and the axis of the tool handle 121 is parallel to the axis of the cutting disc 11. The tool head 122 is arranged at the telescopic end of the tool handle 121 and is located between the cutting disc 11 and the pipe; the supporting mechanism includes a carrying roller group, and the carrying roller group is used to support the pipe and can drive the pipe to rotate around its own axis.

[0030] Compared with the prior art: During the use of this embodiment, the bearing roller set in the support mechanism can drive the pipe to rotate around its own axis. Then, during the rotation of the cutting disc 11, it approaches the pipe to cut the pipe. At the same time, the scraper 12 approaches the pipe during the process of the cutting depth of the cutting disc 11 gradually increasing, and performs a cutting operation on the port part of the pipe, forming a chamfer on the end face of the pipe while removing the burrs on the pipe, thus solving the technical problem that the outer edge of the end face of the existing pipe cannot be chamfered during the cutting process. In addition to the above beneficial effects, in this embodiment, the feed amount of the scraper 12 can be controlled by adjusting the extended length of the scraper 12, and the scraper 12 is extended during the retraction process of the cutting disc 11 to chamfer the inner edge of the pipe.

[0031] Based on the above embodiment, in order to drive the rotation and horizontal movement of the cutting disc 11, in a feasible implementation manner, the cutting mechanism further includes a driving part 13 and a mounting part 14. The driving part 13 includes a first driving motor 131, a first guide rail 132, and a telescopic oil cylinder 133. The mounting part 14 includes a mounting frame 141. The mounting frame 141 is slidably arranged on the first guide rail 132. The first guide rail 132 extends in the horizontal direction and is parallel to the axis of the cutting disc 11. The cutting disc 11 is rotatably arranged on the mounting frame 141. The first driving motor 131 is arranged on the mounting frame 141 and is used to drive the cutting disc 11 to rotate. The telescopic oil cylinder 133 is arranged side by side on one side of the first guide rail 132 and is used to drive the mounting frame 141 to move along the first guide rail 132. With the above settings, in this embodiment, the rotation of the telescopic oil cylinder 133 can drive the mounting frame 141 to move, and then drive the cutting disc 11 arranged on the mounting frame 141 to move horizontally. The first driving motor 131 is arranged on the mounting frame 141 and is located on the side of the cutting disc 11 away from the pipe. The first driving motor 131 drives the cutting disc 11 to rotate, and the cutting operation of the pipe is completed during the rotation of the cutting disc 11. After cutting, the pipe located downstream moves away from the pipe located upstream, leaving space for the chamfering operation of the cutting mechanism. At the same time, in order to perform the chamfering operation on the pipe located downstream, on the other side of the pipe, there is another cutting mechanism symmetrically arranged with the cutting mechanism in this embodiment, making the structural setting of this embodiment more reasonable and conducive to improving the processing efficiency of this embodiment for the pipe.

[0032] Based on the above embodiments, an alternative implementation manner is proposed. Specifically, the driving part 13 further includes a shaft cylinder 134, a driving rod 135, a driving sleeve 136 and a mounting sleeve 137. The shaft cylinder 134 is rotatably arranged on the mounting frame 141 and is coaxially arranged on one side of the cutting disc 11. The first driving motor 131 is rotationally connected to the cutting disc 11 through the shaft cylinder 134. The driving rod 135 is coaxially arranged in the shaft cylinder 134, and a bevel gear ring is coaxially arranged at one end of the driving rod 135 facing the cutting disc 11. The driving sleeve 136, the mounting sleeve 137 and the tool handle 121 are coaxially arranged, and the driving sleeve 136 is rotatably arranged on the inner wall of the shaft cylinder 134 around its own axis. The outer periphery of the bottom of the driving sleeve 136 is in meshing fit with the bevel gear ring. The mounting sleeve 137 is fixedly arranged on the inner wall of the shaft cylinder 134. The tool handle 121 rotates synchronously with the driving sleeve 136, and the bottom of the tool handle 121 is slidably inserted into the driving sleeve 136 along its own axis. An external thread that is threadedly adapted to the inner wall of the mounting sleeve 137 is provided on the outer periphery of the tool handle 121. In this embodiment, the rotation of the driving rod 135 can drive the rotation of the driving sleeve 136, and then the rotation of the driving sleeve 136 can drive the rotation of the tool handle 121. During the rotation of the tool handle 121, the axial displacement can be realized by using the threaded fit between itself and the inner wall of the mounting sleeve 137, so as to drive the cutter head 122 to expand and contract.

[0033] In a feasible implementation manner, the driving part 13 further includes a driving cylinder 1311, a first gear 1312, a first gear ring 1342 and a second gear 1351. The driving cylinder 1311 is arranged on the mounting frame 141 and is used to drive the first driving motor 131 to move along its own axis. The first gear 1312 is arranged at the power output end of the first driving motor 131. The first gear ring 1342 is sleeved on the outer periphery of the shaft cylinder 134 and can be meshed with the first gear 1312. The second gear 1351 is arranged at one end of the driving rod 135 away from the cutting disc 11 and can be meshed with the first gear 1312. With the expansion and contraction of the telescopic oil cylinder 133, the first driving motor 131 has a first state of driving the first gear ring 1342 to rotate, a second state of driving the second gear 1351 to rotate, and a third state of simultaneously driving the first gear ring 1342 and the second gear 1351 to rotate. In this embodiment, the driving cylinder 1311 can drive the first driving motor 131 to move horizontally through its own expansion and contraction. During the horizontal movement of the first driving motor 131, the first gear 1312 is respectively in meshing transmission with the first gear ring 1342 or the second gear 1351, or simultaneously in meshing transmission with the first gear ring 1342 and the second gear ring, so as to simultaneously drive the tool handle 121 to expand and contract during the process of driving the cutting disc 11 to rotate, and further realize the stepless transformation of the expansion and contraction of the scraper 12 during the process of the cutting disc 11 cutting the pipe.

[0034] Optionally, in order to conveniently increase the output power of the first driving motor 131, a motor specification with a larger volume is required. In this regard, the method of using the driving cylinder 1311 to drive the first driving motor 131 to move needs to be improved. The specific improvement ideas are as follows:

[0035] In this embodiment, the first driving motor 131 is arranged on one side of the cutting disc 11. The first gear 1312, as the power output end of the first driving motor 131, is arranged in the mounting frame 141 and is drivingly connected to the output shaft of the first driving motor 131 through a belt drive. The driving cylinder 1311 is also arranged in the mounting frame 141. A rotatable transmission wheel 1313 is provided at the telescopic end of the driving cylinder 1311. The first gear 1312 is drivingly connected to the first tooth ring 1342 on the outer periphery of the cylinder shaft through the transmission wheel 1313. The driving cylinder 1311 transmits the driving force of the first gear 1312 to the first tooth ring 1342 or the second gear 1351 by driving the transmission wheel 1313 to move axially; thereby driving the cutting disc 11 to rotate while driving the tool handle 121 to expand and contract, solving the technical problems of insufficient blanking efficiency of the existing cutting disc 11 and inconvenient use caused by the too large volume of the driving motor.

[0036] In a feasible implementation manner, a sealing cover 1341 is provided at the end of the shaft cylinder 134 away from the cutting disc 11. The sealing cover 1341 is provided with a sealing through hole adapted to the rotation of the driving rod 135 along its own axis. With such a setting, the sealing cover 1341 can not only prevent foreign objects from entering the shaft cylinder 134, but also play a guiding role in the rotation of the driving rod 135, preventing the driving rod 135 from deviating in position during the rotation process.

[0037] Furthermore, a feasible implementation manner is proposed. Specifically, the carrying roller group includes a first support roller 31 and two second support rollers 32 whose axes are all parallel to the axis of the cutting disc 11. The first support roller 31 is a driving roller and is arranged directly below the pipe. The two second support rollers 32 are respectively movably arranged on the opposite sides of the first support roller 31, and the moving directions of the two second support rollers 32 are both perpendicular to the axial direction of the pipe. In this embodiment, the two second support rollers 32 can position the pipe to prevent the pipe from shifting in position during rotation. The first support roller 31 mainly plays the role of carrying the weight of the entire pipe and driving the pipe to rotate. In addition, in this embodiment, the two second support rollers 32 can cooperate with each other to move the cut pipe to the conveying device and straighten the pipe subsequently transferred to the carrying roller group, thereby improving the cutting efficiency of the pipe.

[0038] Based on the above embodiments, in order to facilitate the adjustment of the positions of the two second support rollers 32, in some embodiments, the support mechanism includes a support base 33 and two mounting cross arms 34. The first support roller 31 is rotatably arranged on the support base 33. One end of the mounting cross arm 34 is hinged to the support base 33, and the other end can swing around the first support roller 31. Moreover, the rotation axis of the mounting cross arm 34 is coaxial with the first support roller 31. The second support roller 32 is rotatably connected to the mounting cross arm 34. With such an arrangement, in this embodiment, the relative positions of the two second support rollers 32 can be adjusted through the mutual cooperation of the two mounting cross arms 34 to better position the pipe or move the pipe to other workstations. Further, in the above embodiment, a plurality of mounting holes are formed in the mounting cross arm 34 along its length direction for mounting the second support roller 32, so as to facilitate adapting the second support roller 32 to different positions on the mounting cross arm 34, enabling the mounting roller set in this embodiment to be adapted to pipes of different specifications. At the same time, in order to facilitate the adjustment of the position of the support base 33, preferably, the support mechanism further includes a second guide rail 35. The second guide rail 35 extends along the axial direction of the pipe, and the support base 33 is slidably adapted to the second guide rail 35. In this embodiment, by adjusting the position of the support base 33, the cutting point of the pipe can be accurately positioned, preventing the size of the pipe after cutting from not meeting the practical requirements, and being beneficial to reducing the design redundancy of the pipe and lowering the production cost of the pipe.

[0039] In summary, compared with the prior art, during the use of the present invention, the support mechanism can drive the pipe to rotate. Furthermore, the present invention can cut the pipe through the rotation and horizontal movement of the cutting disc 11, and chamfer the outer edge of the pipe port by the telescopic movement of the scraping knife 12. The load-bearing roller set in the support mechanism can drive the pipe to rotate around its own axis. Then, during the rotation of the cutting disc 11, it approaches the pipe to realize the cutting operation of the pipe. At the same time, the scraping knife 12 can approach the pipe during the process of gradually increasing the cutting depth of the cutting disc 11 to chamfer the outer edge of the pipe port. Similarly, during the retraction of the cutting disc 11, the scraping knife 12 is extended to chamfer the inner edge of the pipe port. And the present invention can realize the above process through the mutual cooperation of the first driving motor 131 and each gear by setting the corresponding driving part 13. The telescopic movement of the entire scraping knife 12 is stable and controllable, making the overall structural arrangement of the pipe blanking device in the present invention more reasonable. Moreover, in this embodiment, two cutting mechanisms arranged in a mirror image can be set to chamfer the upstream pipe and the downstream pipe after cutting simultaneously, so as to further improve the blanking efficiency of the pipe in the present invention.

[0040] Based on the same inventive concept, the present invention also provides a pipe production line, which includes the pipe blanking device described above.

[0041] Compared with the prior art, the pipe production line in the present invention has all the beneficial effects of the above pipe blanking device, and will not be repeated here.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
