Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing technology, and in particular to a precision straight seam welded pipe forming equipment. Background Technology

[0002] Straight seam welded pipe refers to steel pipes made by welding hot-rolled or cold-rolled steel plates or strips with straight seams on welding equipment. During the processing of welded pipes, forming equipment is needed to roll and shape them.

[0003] In the existing technology, during the forming process of welded pipe, it is necessary to treat its surface or correct its roundness. Due to the lack of full circumference symmetry in the spatial distribution of the rollers and the difficulty in achieving continuous coverage of the full circumference of the welded pipe by the movement mode, when the welded pipe is continuously conveyed along the axial direction of the production line, it will cause significant differences in the amount of deformation and surface processing at different circumferential positions of the welded pipe, resulting in inaccurate roundness of the welded pipe, inconsistent surface quality, or microcracks caused by stress concentration. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when the surface of the welded pipe is treated or the roundness is corrected, the lack of symmetry in the spatial distribution of the rollers and the difficulty in achieving continuous coverage of the full circumference of the welded pipe by the movement mode lead to significant differences in the amount of deformation and the degree of surface processing at different circumferential positions of the welded pipe. Therefore, a precision straight seam welded pipe forming equipment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precision straight seam welded pipe forming equipment, including a processing table, a forming guide mechanism installed on the top side of the processing table, a processing mechanism installed on one side of the processing table, the processing mechanism including a support frame, one side of the support frame being fixedly connected to one side of the processing table, a rotating collar being rotatably connected to the inner side of the support frame, and fixed plates being fixedly connected to both ends of the rotating collar, multiple fixed plates being arranged in a uniform ring array around the center line of the rotating collar, a second slot being opened on one side of the fixed plate, a sliding rod being slidably connected inside the second slot, a connecting rod being fixedly connected to one end of the sliding rod, and a processing roller being rotatably connected to one end of the connecting rod.

[0006] Preferably, a first motor is fixedly connected to the bottom side of the support frame, and a belt assembly is installed at the output end of the first motor and one end of the rotating collar.

[0007] Preferably, a fixing plate is attached to one side of the fixing plate, and a first slot is provided on the fixing plate, with the sliding rod externally movably connected to the inside of the first slot.

[0008] Preferably, a fixing rod is fixedly connected between the two fixing discs, and a first electric push rod is rotatably connected to the middle of the fixing rod. The other end of the first electric push rod is rotatably connected to the inner ring surface of the rotating collar.

[0009] Preferably, the forming guide mechanism includes a first connecting block and a second connecting block. A rotating rod is rotatably connected to the middle of both the first and second connecting blocks. A guide roller is fixedly connected to one end of the rotating rod. A second electric push rod is fixedly connected to one side of the processing table. One end of the second electric push rod passes through one side of the processing table and is fixedly connected to one end of the second connecting block.

[0010] Preferably, a limiting groove is provided on the top side of the processing table, the outer side of the first connecting block is fixedly connected to the inner side of the limiting groove, and the outer side of the second connecting block is slidably connected to the inner side of the limiting groove.

[0011] Preferably, the other ends of the two rotating rods are fixedly connected to gears, and a transmission wheel meshes between the two gears. The transmission wheel is rotatably connected to the bottom of the processing table. One end of one of the gears is fixedly connected to a second motor, and one side of the second motor is fixedly connected to the bottom side of the processing table.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the first motor works to drive the rotating collar to rotate within the support frame, causing multiple fixed plates and connected sliding rods, connecting rods, and processing rollers to perform synchronous circumferential motion. The first electric push rod pushes the fixed rod and fixed plate to move, causing the sliding rod to slide to adjust the radial position of the processing roller, thereby achieving the contact between the processing roller and the outer surface of the welded pipe. This allows the processing roller to perform uniform treatment on the surface of the welded pipe without dead angles, avoiding uneven stress caused by local treatment.

[0014] 2. In this utility model, the gear connected to the second motor is driven to rotate, so that the two rotating rods drive the guide rollers on the first connecting block and the second connecting block to rotate synchronously, providing conveying power for the steel strip. The second electric push rod pushes the second connecting block to slide along the limiting groove, adjusting the distance between the two guide rollers to adapt to welded pipes of different diameters, ensuring that the welded pipe is conveyed smoothly, avoiding slippage or deviation, and ensuring the accuracy of subsequent forming processes.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a precision straight seam welded pipe forming equipment, including a processing table 1. A forming guide mechanism 3 is installed on the top side of the processing table 1, and a processing mechanism 2 is installed on one side of the processing table 1. The processing mechanism 2 includes a support frame 21, one side of the support frame 21 is fixedly connected to one side of the processing table 1, and a rotating collar 213 is rotatably connected to the inner side of the support frame 21. Both ends of the rotating collar 213 are fixedly connected to fixed plates 29. Multiple fixed plates 29 are arranged in a uniform ring array around the center line of the rotating collar 213. A second slot 28 is opened on one side of the fixed plate 29, and a sliding rod 26 is slidably connected inside the second slot 28. One end of the sliding rod 26... A connecting rod 25 is fixedly connected, and a processing roller 212 is rotatably connected to one end of the connecting rod 25; a first motor 23 is fixedly connected to the bottom side of the support frame 21, and a belt assembly 22 is installed at the output end of the first motor 23 and one end of the rotating collar 213; a fixed plate 210 is attached to one side of the fixed plate 29, and a first slot 27 is opened on the fixed plate 210, and the external part of the sliding rod 26 is movably connected to the inside of the first slot 27; a fixed rod 211 is fixedly connected between the two fixed plates 210, and a first electric push rod 24 is rotatably connected to the middle of the fixed rod 211, and the other end of the first electric push rod 24 is rotatably connected to the inner ring surface of the rotating collar 213.

[0023] The first electric push rod 24 operates, pushing the fixed rod 211 to move, which in turn drives the fixed plate 210 to move radially along the rotating collar 213. The first slot 27 cooperates with the sliding rod 26, allowing the sliding rod 26 to slide within the second slot 28 of the fixed plate 29, thus ensuring that the processing roller 212 is in contact with the outer surface of the welded pipe. The belt assembly 22 consists of two pulleys and a conveyor belt. The first motor 23 operates, driving the rotating collar 213 to rotate inside the support frame 21 via the belt assembly 22. Since the fixed plate 29 and the rotating collar 213 are fixed and arranged in a circular array, the rotating collar 213 will drive the fixed plate 29 and subsequent connecting components to perform synchronous circumferential motion, enabling the processing roller 212 to perform uniform circumferential processing on the welded pipe, avoiding uneven stress in localized processing.

[0024] Example 2: Figure 1 and Figure 4 As shown, the forming guide mechanism 3 includes a first connecting block 37 and a second connecting block 38. A rotating rod 34 is rotatably connected to the middle of both the first connecting block 37 and the second connecting block 38. A guide roller 31 is fixedly connected to one end of the rotating rod 34. A second electric push rod 32 is fixedly connected to one side of the processing table 1. One end of the second electric push rod 32 passes through one side of the processing table 1 and is fixedly connected to one end of the second connecting block 38. A limiting groove 33 is opened on the top side of the processing table 1. The outer side of the first connecting block 37 is fixedly connected to the inner side of the limiting groove 33. The outer side of the second connecting block 38 is slidably connected to the inner side of the limiting groove 33. Gears 35 are fixedly connected to the other ends of the two rotating rods 34. A transmission wheel meshes between the two gears 35. The transmission wheel is rotatably connected to the bottom of the processing table 1. A second motor 36 is fixedly connected to one end of one of the gears 35. One side of the second motor 36 is fixedly connected to the bottom side of the processing table 1.

[0025] The second motor 36 operates, driving the fixed gear 35 to rotate. Since the two gears 35 are meshed through a transmission wheel, the other gear 35 rotates synchronously, thereby driving the two rotating rods 34 and the guide roller 31 to rotate synchronously. The second electric push rod 32 operates, pushing the second connecting block 38 to slide along the limiting groove 33 of the processing table 1, adjusting the distance between the guide roller 31 on the second connecting block 38 and the guide roller 31 on the first connecting block 37. The formed steel strip passes through the space between the two guide rollers 31. The rotation of the guide rollers 31 drives it to move along the production line. Adjusting the distance between the guide rollers 31 can adapt to welded pipes of different diameters, guiding them to accurately enter the subsequent process, providing stable power for the welded pipe, avoiding slippage and deviation, and ensuring forming accuracy.

[0026] The usage and working principle of this device are as follows: The second motor 36 drives the gear 35 connected to it to rotate. With the cooperation of the two gears 35 and the transmission wheel, the two rotating rods 34 rotate synchronously, which in turn drives the guide rollers 31 on the first connecting block 37 and the second connecting block 38 to rotate synchronously. At the same time, the second electric push rod 32 pushes the second connecting block 38 to slide along the limiting groove 33, adjusting the distance between the two guide rollers 31 to match the initial welded pipe specifications. The first motor 23 drives the rotating collar 213 to rotate inside the support frame 21, so that the multiple fixed plates 29 fixed to the rotating collar 213 and arranged in a ring array can move in a circular motion synchronously. The first electric push rod 24 pushes the fixed rod 211 and the fixed disk 210 to move radially, adjusting the radial position of the processing roller 212 so that it fits the outer surface of the welded pipe. As the rotating collar 213 rotates, the processing roller 212 performs uniform processing on the welded pipe around the entire circumference.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
