Abstract
Description
Technical Field
[0001] This utility model relates to the field of straight seam welded pipe technology, and in particular to a straight seam welded pipe straightening support tool. Background Technology
[0002] Straight seam welded pipe is an important industrial profile, and its straightness is one of the key indicators for evaluating product quality. It needs to be accurately corrected through a straightening process. The straightening machine applies pressure to the pipe through the upper pressure roller, and the support fixture set below it is the core load-bearing component. Its performance directly affects the straightening effect and production efficiency.
[0003] In traditional straight seam welded pipe straightening support fixtures, the traditional supports are mostly point or line contact forms to fix the welded pipe. However, most support fixtures are single fixed structures. To adapt to different pipe diameters, it is usually necessary to replace the entire set of fixtures or a large number of parts, resulting in excessive downtime and inability to meet the production needs of multiple varieties. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a straightening support fixture for straight seam welded pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A straight seam welded pipe straightening support fixture includes a frame, characterized in that multiple support frames are fixedly connected to the top of the frame, and the same welded pipe body is placed on the top of each of the multiple support frames. A guide rail is fixedly connected to the top of the frame, and two sliders are slidably connected in the guide rail. Each of the two sliders has a through hole at its top, and a V-block is inserted into each through hole. A bidirectional threaded rod is rotatably connected between the inner walls of the two sides of the frame, and the bidirectional threaded rod passes through the two sliders located in the same guide rail.
[0006] As a further embodiment of this utility model, one end of the bidirectional threaded rod passes through the frame and is fixedly connected to a handwheel, and the outer side of the handwheel is integrally formed with anti-slip texture.
[0007] As a further embodiment of this utility model, the bottom of each of the multiple V-shaped blocks and sliders is provided with a socket, a pin is inserted into each of the multiple sockets, and an anti-slip pad is fixedly connected to one side of each of the multiple V-shaped blocks.
[0008] As a further embodiment of this utility model, dustproof scraping rings are fixedly connected to both sides of the plurality of sliders, and a plurality of soft brushes are provided on the inner side of the plurality of dustproof scraping rings.
[0009] As a further embodiment of this utility model, one end of the bidirectional threaded rod is provided with a threaded groove, and a locking nut is threadedly connected inside the threaded groove, with the locking nut in contact with the frame. The beneficial effects of this utility model are as follows: 1. This utility model is equipped with an adjustable V-block and a bidirectional threaded rod transmission structure. The drive assembly drives the two bidirectional threaded rods to rotate synchronously, so that the two sliders in the same guide rail move towards or away from each other along the guide rail, thereby adjusting the distance between the V-blocks to adapt to welded pipe bodies of different diameters. There is no need to replace the tooling as a whole, which shortens the equipment downtime and improves the production efficiency.
[0010] 2. This utility model is equipped with a V-block, which is detachably connected to the slider via a pin. When the V-block is worn or needs to be replaced with a different specification, it can be quickly replaced simply by pulling out the pin, further enhancing the versatility and ease of maintenance of the tooling.
[0011] 3. This utility model is equipped with a dustproof scraper ring, which can remove dust and impurities from the surface of the bidirectional threaded rod when the slider moves by using the soft brush on the inner side. This prevents particulate matter from affecting the sliding accuracy of the bidirectional threaded rod surface and extends the service life of the device. Attached Figure Description

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] Reference Figures 1-3A straight seam welded pipe straightening support fixture includes a frame 1. Multiple support frames 2 are bolted to the top of the frame 1, and the same welded pipe body 3 is placed on the top of each support frame 2. A guide rail 13 is bolted to the top of the frame 1, and two sliders 14 are slidably connected within the guide rail 13. Each slider 14 has a through hole at its top, and a V-block 4 is inserted into each through hole. Two bidirectional threaded rods 12 are rotatably connected between the inner walls of both sides of the frame 1, and the bidirectional threaded rods 12 pass through the two sliders 14 located within the same guide rail 13. In use, the bidirectional threaded rods 12 are threadedly connected to the sliders 14, and the sliders 14 are limited by the guide rail 13. The two sliders 14 located within the same guide rail 13 will move towards or away from each other along the guide rail 13, thereby adjusting the distance between the two sets of V-blocks 4 until the V-blocks 4 fit against the outer wall of the welded pipe body 3. This accommodates welded pipe bodies 3 of different diameters without requiring a complete replacement of the fixture, shortening equipment downtime and improving production efficiency.
[0015] In this utility model, one end of the bidirectional threaded rod 12 passes through the frame 1 and is welded with a handwheel 6. The outer side of the handwheel 6 is integrally formed with anti-slip texture. The bottom of the multiple V-blocks 4 and the slider 14 are provided with insertion holes, and pins 15 are inserted into the multiple insertion holes. Anti-slip pads 17 are glued to one side of the multiple V-blocks 4. The anti-slip pads 17 on one side of the V-blocks 4 can increase the friction between the anti-slip pads and the welded pipe body 3 and prevent the welded pipe body 3 from sliding during the straightening process.
[0016] In particular, dustproof scraper rings 16 are fixed to both sides of multiple sliders 14 by bolts. Multiple soft brushes are provided on the inner side of multiple dustproof scraper rings 16. During the movement of sliders 14, the soft brushes on the inner side of the dustproof scraper rings 16 on both sides will clean the surface of the bidirectional threaded rod 12, scraping off the attached dust and impurities, and preventing particles from entering the threaded mating surface between sliders 14 and bidirectional threaded rod 12. The outer side of the bidirectional threaded rod 12 is provided with a threaded groove, and a locking nut 5 is threadedly connected in the threaded groove. Tightening the locking nut 5 will make it closely contact the outer wall of the frame 1, and the rotation of the bidirectional threaded rod 12 will be restricted by friction, thereby fixing the position of the V-block 4.
[0017] Working principle: When straightening and supporting welded pipe bodies 3 of different diameters is required, the operator can first rotate the handwheel 6, which will cause the bidirectional threaded rod 12 to rotate simultaneously. Since the bidirectional threaded rod 12 is threadedly connected to the slider 14 and the slider 14 is limited by the guide rail 13, the two sliders 14 located in the same guide rail 13 will move towards or away from each other along the guide rail 13, thereby adjusting the distance between the two V-blocks 4 until the V-blocks 4 are in contact with the outer wall of the welded pipe body 3. At this time, after the adjustment is completed, if the V-blocks 4 are worn or need to be replaced with different specifications to adapt to special pipe diameters, simply pull out the pin 15 to remove the V-blocks 4 from the through hole of the slider 14, replace the new V-blocks 4, and reinsert the pin 15 to complete the installation.
[0018] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
