Description

Technical Field

[0001] This invention relates to the field of grooving machines, and in particular to a grooved fire-fighting pipeline grooving machine. Background Technology

[0002] A grooving machine is a hydraulic tool used for grooving pipe ends in pipe connections. It can be used for various metal pipes such as carbon steel pipes, galvanized pipes, and stainless steel pipes. It is an important tool for pipe connection. The application of grooving machines is inseparable from the development of grooving connections. In the past, pipe connections were generally made using welding, threads, flanges, etc., but these methods either caused pollution, required secondary galvanizing, were complicated and expensive to install, or were difficult and costly to maintain. Therefore, many engineering projects have now chosen grooving as a new type of connection method.

[0003] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials and transport fire extinguishing water, gas or other media. To facilitate the connection of fire protection pipelines, grooving machines are often used for processing and connection. However, traditional grooving machines require manual feeding and do not have automatic feeding functions. If processing heavy pipelines, it will greatly increase the labor intensity of people and reduce work efficiency.

[0004] To address these issues, we propose a grooved fire-fighting pipe grooving machine. Summary of the Invention

[0009] In a further embodiment, each of the clamping blocks has an installation groove at its front end, the conveying roller is rotatably connected to the inner cavity of the installation groove, and each of the clamping blocks has an arc-shaped groove on its inner side.

[0010] In a further embodiment, a grooving mechanism is installed on the top of the processing platform. The grooving mechanism includes a fixed plate, and a fixed seat is fixedly connected to the left side of the top of the fixed plate.

[0014] In a further embodiment, a rotating rod is provided on the left side of the reducer, and a knurling wheel is fixedly connected to the left side of the rotating rod. A knurling groove is formed at the middle of the outer surface of the knurling wheel.

[0015] In a further embodiment, a second limiting groove is provided at both the top and bottom of the inner cavity of the slide groove. The second limiting groove is symmetrically provided, and the top and bottom of the slider are movably connected to the right side of the inner cavity of the second limiting groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Firstly, in this invention, the third cylinder is activated to drive the lifting seat downwards. Then, the output of the first servo motor drives the first gear to rotate. The first gear drives the threaded rod to rotate through the second gear. The threaded rod drives the slider to move to the left, placing the pipe inside the clamping block. The fourth cylinder drives the clamping block to move inwards, clamping the pipe between the inner sides of the two conveying rollers. The output of the second servo motor drives the conveying roller to rotate. After the second cylinder extends and retracts, its output drives the second limit block to push to the left, placing the clamped pipe to the left of the knurling wheel. The second servo motor continues to drive the conveying roller to rotate, continuously conveying the pipe to the right until it is fitted onto the outer surface of the knurling wheel. The clamping roller then performs the grooving operation. Through the combination of the above technologies, automatic feeding can be performed quickly and easily.

[0020] Secondly, in this invention, after the pipe is transported to the outer surface of the knurling wheel, the first cylinder is activated to extend and retract. The first cylinder drives the lifting rod to move downward in the inner cavity of the first limiting groove. At the same time, the lifting rod drives the pressing wheel to move downward. The pressing wheel presses the pipe through the convex ring. The convex ring corresponds to the rolling groove on the outer surface of the knurling wheel. The output end of the drive motor drives the rotating rod to rotate after being reduced by the reducer. The rotating rod drives the knurling wheel to rotate, so that the knurling wheel and the pressing wheel clamp the pipe to perform the grooving operation. Attached Figure Description

[0041] Specifically, the left end of the threaded rod 404 is fixedly connected to a first limiting block 414, and the first limiting block 414 is circular.

[0042] Specifically, the right side of the second cylinder 402 is movably connected to the bottom frame 401, and the output end of the second cylinder 402 is movably connected to the outer side of the second limit block 417.

[0043] In this invention, after the pipe is transported to the outer surface of the knurling wheel 201, the first cylinder 202 is activated to extend and retract. The first cylinder 202 drives the lifting rod 210 to move downward in the inner cavity of the first limiting groove 211. At the same time, the lifting rod 210 drives the pressing wheel 207 to move downward. The pressing wheel 207 presses the pipe through the convex ring 208. The convex ring 208 corresponds to the rolling groove 212 on the outer surface of the knurling wheel 201. The output end of the drive motor 205 drives the rotating rod 213 to rotate after being reduced by the reducer 204. The rotating rod 213 drives the knurling wheel 201 to rotate, so that the knurling wheel 201 and the pressing wheel 207 clamp the pipe for grooving operation.

[0044] The working principle of this invention is as follows: First, the third cylinder 406 is activated to extend and retract, causing the lifting seat 410 to move downwards. Then, the first servo motor 408 is activated, driving the first gear 409 to rotate through its output. The first gear 409 then drives the second gear 419 to rotate, which in turn drives the threaded rod 404 to rotate. The threaded rod 404 drives the slider 411 to move to the left within the inner cavity of the slide groove 407. The slider 411, through the connecting rod 403, drives the bottom frame 401 to move to the left, causing the bottom loading mechanism 4 to move to the left, positioning the side plate 405 at the lower left of the processing platform 1. The pipe is then placed inside the clamping block 420. The fourth cylinder 422 is activated to extend and retract, causing the clamping block 420 to move inwards, clamping the pipe between the inner sides of the two conveying rollers 424. After the second servo motor 421 is activated, its output drives the conveying rollers 424 to rotate, moving the pipe towards... Conveying to the right, at this time, by activating the extension and retraction of the second cylinder 402, the output end of the second cylinder 402 drives the second limit block 417 to push to the left. The second limit block 417 drives the movable rod 412 to push to the left within the inner cavity of the movable groove 413. At the same time, the second limit block 417 drives the lifting base plate 416 to push to the upper left, so that the clamped pipe is placed to the left of the knurling wheel 201. Continue to control the second servo motor 421 to drive the conveying roller 424 to rotate, and the conveying roller 424 continuously pushes the pipe towards... The pipe is conveyed from the right until it is fitted onto the outer surface of the knurling wheel 201. The first cylinder 202 is then activated to extend and retract. The first cylinder 202 drives the pressing wheel 207 to move downward through the lifting rod 210 until the convex ring 208 on the outer surface of the pressing wheel 207 presses down on the pipe. After the drive motor 205 is turned on, the output end of the drive motor 205 drives the rotating rod 213 to rotate. The rotating rod 213 drives the knurling wheel 201 to rotate, so that the knurling groove 212 cooperates with the pressing wheel 207 to perform the grooving operation.
