Description

Technical Field

[0001] The utility model relates to the technical field of curved pipe production and processing, in particular to a curved pipe flattening device. Background Art

[0002] At present, a curved pipe flattening device is a device dedicated to flattening curved pipes. The design of this device can accurately and efficiently meet the needs of flattening curved pipes. Its working principle is mainly to apply pressure to the curved pipe through mechanical or hydraulic means, so that it is flattened within a certain area, so as to achieve the purpose of changing the shape of the curved pipe or performing other processing.

[0003] Most of the existing curved pipes need a mold with a flattened shape to assist in flattening when being flattened. However, the flattened sizes of curved pipes are different, and the mold needs to be frequently replaced when flattening different curved pipes. The mold replacement is rather troublesome. Not only auxiliary tools such as wrenches, screws and clamps are needed, but also slow movement is required before and after replacement to avoid scratching the machine, which results in a relatively long time for replacing a mold. Moreover, the price of the mold is relatively expensive, and customizing one for each size is also a relatively large expense. Therefore, it is necessary to design a curved pipe flattening device with simple production and convenient replacement of the flattening mold. Summary of the Utility Model

[0004] In order to solve the technical problem of slow replacement speed of the mold for flattening curved pipes, the utility model provides a curved pipe flattening device.

[0005] The utility model is realized by the following technical solutions: A curved pipe flattening device includes a flattening table. A flattening component for flattening the curved pipe is provided on one side of the flattening table. A limiting component for limiting the shape of the curved pipe during flattening is provided between the flattening component and the flattening table. A pulling component for automatically pulling and moving the pipe to facilitate automatic flattening of the long pipe is provided on one side of the limiting component. The flattening component includes a support frame fixedly installed on one side of the flattening table, a hydraulic device fixedly installed on the support frame, and a flattening plate fixedly installed on the hydraulic end of the hydraulic device.

[0006] Through the above technical solutions, the limiting component is replaced according to the degree of flattening required for the curved pipe. The flattening component is started to flatten the curved pipe. If the curved pipe is long, the pulling component can be used to pull the curved pipe so that the flattening component can continuously flatten the curved pipe.

[0007] As a further improvement of the above solution, a first installation groove is opened on one side of the flattening plate, and a second installation groove is opened on one side of the flattening table.

[0008] Through the above technical solutions, the first installation groove and the second installation groove can facilitate the replacement of the limiting component.

[0009] As a further improvement of the above solution, the limiting component includes a first limiting plate slidably installed inside the first installation groove and a second limiting plate slidably installed inside the second installation groove, and the first limiting plate is adapted to the second limiting plate.

[0010] Through the above technical solution, it is convenient to draw out the first limiting plate and the second limiting plate for replacement.

[0011] As a further improvement of the above solution, two first threaded holes are opened on one side of the flattening plate, two baffles are fixedly installed on one side of the first limiting plate, first threaded columns are provided on one side of each of the two baffles, and one ends of the two first threaded columns penetrate through the adjacent baffles and extend into the interiors of the adjacent first threaded holes, and second rotating blocks are fixedly installed at the other ends of the two first threaded columns.

[0012] Through the above technical solution, rotating the first threaded column will fix the baffle, thereby fixing the first limiting plate.

[0013] As a further improvement of the above solution, a plurality of second threaded holes are opened on one side of the flattening table, a second threaded column is threadedly engaged inside each of the second threaded holes, each second threaded column is threadedly engaged with the second limiting plate, and a second rotating block is fixedly installed at one end of each second threaded column.

[0014] Through the above technical solution, rotating the second threaded column will fix the second limiting plate.

[0015] As a further improvement of the above solution, the pulling component includes a servo motor fixedly installed on one side of the flattening table, a driving rod fixedly installed on the output end of the servo motor, and a rubber column sleeved on the driving rod, and one end of the driving rod is rotatably installed on a support plate fixedly installed with the flattening table.

[0016] Through the above technical solution, when the driving rod rotates, the rubber column will rotate, thereby pulling and discharging the flattened curved pipe.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a flattening component, a limiting component and a pulling component, when different-sized flattened curved pipes are required, the limiting component is replaced according to the size. After the replacement is completed, the flattening component is started to flatten the curved pipe, and at the same time, the pulling component is started. When the flattening of the curved pipe is completed, the pulling component will extrude and pull the curved pipe, thereby completing the blanking. Such a setting can not only flatten the curved pipe to different degrees as required, but also quickly replace the limiting component. Description of the Drawings

The flattening component includes a support frame 201 fixedly installed on one side of the flattening table 1, a hydraulic device 202 fixedly installed on the support frame 201, and a flattening plate 203 fixedly installed on the hydraulic end of the hydraulic device 202. Replace the shape-limiting component according to the required degree of flattening of the curved pipe. Start the flattening component to flatten the curved pipe. If the curved pipe is long, the pulling component can be used to pull the curved pipe so that the flattening component can continuously flatten the curved pipe.

[0027] Combine Figures 1-4, a first installation groove 5 is formed on one side of the flattening plate 203, and a second installation groove 6 is formed on one side of the flattening table 1. The limiting assembly includes a first limiting plate 301 slidably installed inside the first installation groove 5 and a second limiting plate 302 slidably installed inside the second installation groove 6. The first limiting plate 301 is adapted to the second limiting plate 302. Two first threaded holes are formed on one side of the flattening plate 203. Two baffles 7 are fixedly installed on one side of the first limiting plate 301. A first threaded post 8 is provided on one side of each of the two baffles 7. One end of each of the two first threaded posts 8 penetrates through the adjacent baffle 7 and extends into the interior of the adjacent first threaded hole. A first rotating block is fixedly installed at the other end of each of the two first threaded posts 8. A plurality of second threaded holes are formed on one side of the flattening table 1. A second threaded post 9 is in threaded fit inside each second threaded hole. Each second threaded post 9 is in threaded fit with the second limiting plate 302. A second rotating block is fixedly installed at one end of each second threaded post 9. The first installation groove 5 and the second installation groove 6 facilitate the replacement of the limiting assembly. Rotating the first threaded post 8 will fix the baffle 7, thereby fixing the first limiting plate 301. Rotating the second threaded post 9 will fix the second limiting plate 302.

[0028] Combined Figure 2 , the pulling assembly includes a servo motor 401 fixedly installed on one side of the flattening table 1, a driving rod 402 fixedly installed on the output end of the servo motor 401, and a rubber column 403 sleeved on the driving rod 402.

[0029] The implementation principle of a curved pipe flattening device in an embodiment of the present application is as follows: When curved pipes with different flattening sizes are required, rotate the first rotating block and the second rotating block to remove the first threaded post 8 and the second threaded post 9. In this way, the first limiting plate 301 and the second limiting plate 302 can be slid and removed. Replace the required first limiting plate 301 and second limiting plate 302 and then use the first threaded post 8 and the second threaded post 9 for fixation. Start the hydraulic device 202 to lower the flattening plate 203 to flatten the curved pipe. The curved pipe will become the shape after the cooperation of the first limiting plate 301 and the second limiting plate 302. Start the servo motor 401. In this way, the driving rod 402 will drive the rubber column 403 to rotate. For slightly shorter curved pipes, only a push is needed and they will be squeezed and dragged by the rubber column 403, thereby discharging the materials. For longer ones, they can be automatically pulled to move the curved pipes. It can complete the automatic flattening processing of the curved pipes. The rubber column 403 can be replaced as needed. It can not only flatten the curved pipes to different degrees according to needs, but also quickly replace the limiting assembly.
