Description

TECHNICAL FIELD

[0001] The present application relates to the field of square tube polishing equipment, in particular to a rotating machine for pipe machining. BACKGROUND

[0002] Square tube is a kind of hollow long strip steel, because the cross section is square, so it is called square tube, generally by strip steel through process treatment and rolling, the strip steel is unpacked, flattened, coiled and welded to form a round tube, and then the round tube is rolled into a square tube, and finally cut into the required length.

[0003] The square tube has different manufacturing processes according to different application scenarios. Some square tubes in the application scenarios need to be polished, such as stainless steel metal fences. The polishing methods for square tubes of different thicknesses are different. Thick square tubes are generally polished one by one using a square tube polishing machine. The square tube passes between two groups of vertically distributed polishing wheels, and then passes between two groups of horizontally distributed polishing wheels, so that the side surface of the square tube can be quickly and efficiently polished.

[0004] Thin square tubes are generally polished simultaneously by multiple groups using a full-automatic double-sided square tube polishing machine. The polishing machine is provided with two groups of square tube fixing frames that can move left and right. The side surface of the fixing frame is provided with multiple groups of rotating top rods. The worker places multiple square tubes between the two groups of fixing frames. The top rods of the fixing frame can clamp the square tube from both ends. The top rod is inserted into the inside of the square tube, so that the polishing wheel can polish the end position of the square tube. If a clamp tool is used to clamp the square tube, the position wrapped by the clamp tool cannot be polished. Two groups of polishing wheels are arranged above and below the square tube. The two groups of polishing wheels actively approach and adhere to the square tube to polish it. During the polishing process, the two groups of fixing frames drive multiple square tubes to move in the same direction, so that the entire section of the square tube can be polished.

[0005] For polishing thin square tubes, the full-automatic double-sided polishing machine uses top rods to clamp the square tube in the form of two groups of top rods inserted into the square tube. This requires the worker to adjust the distance between the two groups of fixing frames when inserting the square tube, which makes it difficult to clamp the square tube, especially when clamping multiple square tubes at the same time. In order to ensure that the square tube does not shake during polishing, the top rod exerts a large force on the square tube, which makes it difficult to remove the square tube from the top rod after polishing is completed.

The distance between the lap joint plate clamping grooves needs to be matched with the size of the square tube. If the distance between the lap joint plate clamping grooves exceeds the size of the square tube too much, the square tube placed in the lap joint plate clamping groove will be misaligned with the ejector rod, affecting the insertion of the ejector rod into the square tube. Therefore, the adjustable spacing of the lap joint plate clamping grooves not only can better help the ejector rod to clamp the square tube, but also can be used to place square tubes of different sizes.

[0049] Example two

[0050] A rotating machine for pipe machining, such as Figures 7-8 As shown, a plurality of sets of lap joint plate clamping grooves 510 and sliding plates 507 are movably installed through the setting of second sliding rails 509 between the sliding plates 507, and the inside of the sliding plate 507 is rotatably connected with a transmission rod 511, the outside of the transmission rod 511 is provided with a plurality of sets of screw grooves, the plurality of sets of screw grooves are symmetrically arranged, and the plurality of sets of screw grooves and the plurality of sets of lap joint plate clamping grooves 510 are matched, a plurality of sets of lap joint plate clamping grooves 510 with adjustable spacing are arranged in the square tube fixing mechanism 5, so that the lap joint plate clamping grooves 510 can lap different sizes of square tubes, the distance between the lap joint plate clamping grooves 510 needs to be matched with the size of the square tube, if the distance between the lap joint plate clamping grooves 510 exceeds the size of the square tube too much, it will cause the square tube placed in the lap joint plate clamping groove 510 to be misaligned with the jacks 515, affecting the insertion of the jacks 515 into the square tube, therefore, the adjustable spacing of the lap joint plate clamping grooves 510 not only can better help the jacks 515 clamp the square tube, but also can be used for placing square tubes of different sizes.

[0051] The working principle of the present application is: when the square tubes of the same batch need to be polished, the staff first starts the lifting mechanism 2, the driving assembly inside the lifting mechanism 2 drives the guide rod 202 to rotate, utilizes the screw principle to make the square tube fixing mechanisms 5 above and below the polishing roller 4 move away from each other, so as to facilitate the staff to place the square tube without being blocked by the polishing roller 4, then adjust the bidirectional movement mechanism between the base 1 and the lifting mechanism 2, so that the distance between the two lifting mechanisms 2 is matched with the length of the square tube.

[0052] Next, the staff adjusts the transmission rod 511 of each square tube fixing mechanism 5 in turn, rotating the transmission rod 511 can adjust the distance of each set of lap joint plate clamping grooves 510, so that the distance of each set of lap joint plate clamping grooves 510 is matched with the size of the square tube, then the staff puts the square tube into each lap joint plate clamping groove 510, then the staff starts the first sliding rail 506, the first sliding rail 506 drives the first sleeve 502 to rotate, the first sleeve 502 drives the second sleeve 503 to rotate through the gear set 504, the first sleeve 502 is screw connected with the first threaded rod 508, the second sleeve 503 is screw connected with the second threaded rod 514, utilizes the screw principle to make the second sleeve 503 rotate to drive the second threaded rod 514 to move, and then the second threaded rod 514 pushes the sliding frame 513 to approach the end of the square tube, the first sleeve 502 rotates to drive the first threaded rod 508 to move, and then the first threaded rod 508 drives the sliding plate 507 to move away from the square tube, that is, a plurality of jacks 515 on the side of the sliding frame 513 are respectively inserted into the inside of the square tube, and the lap joint plate clamping groove 510 on the top of the sliding plate 507 releases the support of the square tube, finally, the jacks 515 located at both ends of the square tube are inserted into the inside of the square tube to clamp it, and the lap joint plate clamping groove 510 will shrink into the inside of the square tube fixing mechanism 5, away from the end of the square tube.

[0053] Next, the staff starts the first drive device 3 to drive the polishing roller 4 to work, and then starts the two sets of lifting mechanisms 2 to adjust the positions of the upper and lower square tube fixing mechanisms 5, that is, to let the square tubes above the polishing roller 4 and the square tubes below the polishing roller 4 actively approach the polishing roller 4 and fit with it. The polishing roller 4 rotates at high speed to polish and grind one side of the square tube. At the same time, the two-way moving mechanism between the base 1 and the lifting mechanism 2 is started, so that the two sets of lifting mechanisms 2 move synchronously, and then the polishing roller 4 can polish and grind the entire section of the square tube.

[0054] When the grinding of one side of the square tube is completed, the third driving device 517 of each set of square tube fixing mechanisms 5 is started, and then the third driving device 517 drives a set of transmission teeth 516 to rotate, and multiple sets of transmission teeth 516 are engaged with each other, and then multiple sets of push rods 515 are rotated 90°. The rotation direction does not affect the polishing and grinding work, that is, each set of square tubes is rotated 90°, so that the other side of the square tube is in contact with the polishing roller 4. According to the above method, it is ensured that the polishing roller 4 grinds and polishes all four sides of the square tube.

[0055] When the square tube is polished and needs to be unloaded, the first driving device 3 and the polishing roller 4 are closed, and then the lifting mechanism 2 is started to make the square tube fixing mechanisms 5 of the upper and lower layers move away from each other to facilitate material removal. Then, according to the above, the second driving device 505 is started to make the top rods 515 of the same layer move away from each other, and the overlapping plate slots 510 of the same layer move closer to each other. When the two sets of top rods 515 move away from each other, the top rod 515 will be pulled out from both ends of the square tube. There may be a part of the top rod 515 at one end of the square tube pulled out, and then the top rod 515 at the other end of the square tube is pulled out, causing the square tube to move with the unpulled top rod 515. At this time, the top rod 515 needs to continue to move away from the initial position for a distance, so that the scraper 518 inside the overlapping plate slot 510 squeezes the end of the square tube, and assists the square tube to be pulled out from the top rod 515. Finally, the staff can remove all the polished square tubes.
