Description

Technical Field

[0001] This invention belongs to the field of metal pipe processing technology, specifically relating to a hydraulic pipeline processing device and its processing method. Background Technology

[0002] Water conservancy pipelines are pipes for supplying water. There are three types of pipes: the first type is metal pipes, such as hot-dip galvanized cast iron pipes with internal plastic lining, copper pipes, and stainless steel pipes; the second type is plastic-coated metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes; and the third type is plastic pipes, such as PB pipes and PP-R pipes. During the processing of water conservancy pipelines, some pipes often need to be drilled at their ends for easy installation. The debris generated during the drilling process can easily scatter everywhere. If the debris enters other components, it can cause mechanical damage and reduce the service life of the machinery.

[0018] A method for processing a hydraulic pipeline processing device includes the following steps:

[0019] S1: First, the metal pipe is clamped and fixed by the clamping mechanism. Specifically, the metal pipe is placed on the lower clamping plate. Then, the upper clamping plate is moved downward by controlling the rotation of the second threaded rod until the upper elastic clamping block contacts and presses against the metal pipe, thereby clamping and fixing the metal pipe by the upper and lower clamping plates. The upper and lower clamping plates are moved synchronously by the first threaded rod, so that the clamping mechanism drives the metal pipe forward until the metal pipe is located in the arc groove of the bearing platform.

[0020] S2: Subsequently, the cutting position of the cutting mechanism is adjusted by the fourth drive motor, and the cutting equipment and the limiting pressure plate are controlled to move downward by the first telescopic cylinder. The height of the limiting pressure plate is lower than the height of the cutting equipment. When the first telescopic cylinder extends, the limiting pressure plate and the cutting equipment can move downward simultaneously. However, the limiting pressure plate first contacts the metal pipe and limits the cutting end of the metal pipe. At this time, the L-shaped mating rod is inserted into the mating sleeve, the limiting pressure plate stops moving downward, and the rectangular slider does not slide to the bottom of the rectangular groove. At this time, the first telescopic cylinder continues to extend until the cutting equipment contacts the metal pipe. Then, the upper clamping plate and the lower clamping plate are driven to rotate by the second drive motor, and the metal pipe rotates accordingly to further achieve cutting. After the cutting is completed, the first telescopic cylinder retracts, and the cutting equipment is separated from the metal pipe. Under the action of the L-shaped mating rod and the mating sleeve, the limiting pressure plate is always in the limiting state.

[0021] S3: During the cutting process, the drilling mechanism descends to drill a hole at one end of the metal pipe. The inclined slide and curved grinding stone on the waste collection mechanism slide into the metal pipe. The debris generated by the drilling mechanism falls through the holes on the curved grinding stone onto the inclined slide, then slides down the inclined slide into the rectangular trough, and finally falls into the collection frame for collection. When the curved grinding stone moves into the metal pipe, it makes contact with its interior. This serves two purposes: firstly, it supports the drilling area during the drilling process to prevent pipe deformation; secondly, it provides preliminary grinding of the interior of the drilling area. The small burrs produced by drilling are removed by grinding. When the metal pipe rotates, the grinding block will also perform preliminary grinding on the outer wall of the metal pipe after drilling, thus removing the small burrs on the outer wall of the metal pipe. The drilling mechanism descends and the waste collection mechanism moves synchronously. When the sixth drive motor works, it can drive the first gear and the second gear to rotate simultaneously. The first gear and the second gear mesh with the first rack and the second rack respectively, further realizing the downward movement of the drilling equipment, the movement of the arc-shaped grinding stone and the inclined slide into the metal pipe, and realizing the functions of drilling and waste collection.

[0022] S4: After cutting and drilling are completed, the metal short tube is rotated to the large slide table by rotating the support platform. At the same time, the cylindrical push rod on the waist-shaped limiting groove will tilt and move upward, pushing the metal short tube in the arc groove outward and falling to the large slide table for collection.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention uses a clamping mechanism to clamp the metal pipe to be processed. The clamping mechanism can move and rotate the metal pipe. The clamping mechanism, together with the cutting mechanism and the drilling mechanism, can cut the metal pipe. The position of the cutting mechanism is adjustable and can cut metal pipes of different lengths. The drilling mechanism is used to drill holes in the cut metal pipe. During the drilling process, the arc-shaped grinding stone can perform preliminary grinding on the inner wall of the metal pipe, and the grinding block can perform preliminary grinding on the outer wall of the metal pipe, thus achieving burr removal after drilling. At the same time, the arc-shaped grinding stone, which is in contact with the inner wall of the metal pipe, can also play a supporting role during the drilling process, preventing deformation of the end of the metal pipe and affecting product quality.

[0025] 2. This invention includes a cutting device and a limiting pressure plate. The limiting pressure plate can move synchronously with the cutting device. When the cutting device retracts upward, it can be temporarily kept still by an L-shaped mating rod and a mating sleeve. Synchronous movement with the cutting device is achieved by a spring, a rectangular slider, and a rectangular groove. The spring can also return the rectangular rod to its initial position. The limiting pressure plate maintains its position on the metal pipe throughout the drilling process, preventing the processing end of the metal pipe from moving and affecting the processing.

[0026] 3. The present invention includes a waste collection mechanism. The inclined slide on the waste collection mechanism can move synchronously with the drilling mechanism until it moves into the inside of the metal pipe. In conjunction with the drilling mechanism, it collects the debris generated by the drilling mechanism. The debris slides down the inclined slide into the collection frame for collection, which prevents the debris from scattering and splashing onto other parts, thus protecting the machine to a certain extent and extending its service life.

[0027] 4. The present invention also includes a processing table that supports the processing end of the metal pipe. After processing, as the support table rotates, the waist-shaped limiting groove and its cylindrical push rod move outward synchronously. The processed semi-finished metal short pipe is pushed onto the large slide for further collection and reprocessing. This avoids the situation where the metal short pipe gets stuck on the support table during the unloading process, eliminating the need for manual removal, reducing the workload of the staff to a certain extent, and saving processing time.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 As shown, a water conservancy pipeline processing device includes a base plate 1. A mounting bracket 3 is fixedly mounted on one side of the base plate 1. The mounting bracket 3 includes several vertically arranged vertical rods and a horizontal rod fixedly mounted at the top of the vertical rods. A clamping mechanism 2 is also mounted on the base plate 1. The clamping mechanism 2 is used to clamp the metal pipe 10 to be processed. The metal pipe 10 can be rotated or moved through the clamping mechanism 2. A cutting mechanism 4 is also slidably mounted on the mounting bracket 3. A limiting mechanism 5 is fixedly mounted on the cutting mechanism 4. The cutting mechanism 4 is used to cut the metal pipe 10, and the limiting mechanism 5 is used to control the cutting end of the metal pipe 10. The bottom plate 1 is equipped with a limit switch to prevent slippage. A drilling mechanism 6 is also slidably mounted on the bottom plate 1. The drilling mechanism 6 is used to drill holes in the cut end of the metal pipe 10. A waste collection mechanism 7 is also slidably mounted on the bottom plate 1. The waste collection mechanism 7 is used to collect the circular waste generated after drilling. A processing table 8 is also mounted on the bottom plate 1. The processing table 8 provides support for the cut end of the metal pipe 10 and has a pushing function to push the processed metal short pipe 11 back into the large slide table 9. The large slide table 9 is fixedly mounted on the bottom plate 1. After the metal short pipe 11 falls onto the large slide table 9, it can slide down from it for collection.

[0042] like Figure 2As shown, the clamping mechanism 2 includes a support platform 201, which is T-shaped. The support platform 201 is fixedly connected to the mounting bracket 3 via an L-shaped connecting rod 203. A first mounting plate 204 is fixedly mounted on the surface of the support platform 201, and a second mounting plate 202 is fixedly mounted on its side. A first limiting rod 205 is fixedly mounted between the first mounting plate 204 and the second mounting plate 202. A first threaded rod 206 is rotatably mounted between the first mounting plate 204 and the second mounting plate 202. A first drive motor 225 is fixedly connected to the second mounting plate 202 via a first motor mounting plate. One end of the first threaded rod 206 passes through the second mounting plate 202 and is fixedly mounted with a first pulley 223. The output end of the first drive motor 225 is fixedly connected to a second pulley 224. A first synchronous belt 226 connects the first pulley 223 and the second pulley 224. A drive motor 225 can drive a first threaded rod 206 to rotate. A first movable seat 207 is threaded onto the first threaded rod 206. A first connecting plate 208 is fixedly connected to the first movable seat 207. A second connecting plate 214 is rotatably mounted on the first connecting plate 208. A third pulley 209 is installed at the rotatable connection between the first connecting plate 208 and the second connecting plate 214. The third pulley 209 can drive the second connecting plate 214 to rotate. A fourth pulley 211 is also installed on the first connecting plate 208. A second belt 210 connects the third pulley 209 and the fourth pulley 211. A second drive motor 212 is connected to the fourth pulley 211. The second drive motor 212 is fixedly mounted on the first connecting plate 208 via a second motor mounting plate 213. When the second drive motor 212 works, the second connecting plate 214 rotates relative to the first connecting plate 208. Figure 2 As shown, the second connecting plate 214 is fixedly connected to the lower clamping plate 216 via the connecting rod 215. The side end of the lower clamping plate 216 is fixedly installed with a motor housing 217. The motor housing 217 contains a third drive motor. The motor housing 217 is rotatably provided with a second threaded rod 219. The motor housing 217 is also fixedly provided with a second limiting rod 220. The third drive motor drives the second threaded rod 219 to rotate. The top ends of the second threaded rod 219 and the second limiting rod 220 are both fixedly installed with the same first horizontal top plate 218. The second threaded rod 219 is also threadedly fitted with an upper clamping plate 221. The upper clamping plate 221 is slidably connected to the second limiting rod 220. Both the upper clamping plate 221 and the lower clamping plate 216 are arc-shaped structures. The inner side of the arc of the upper clamping plate 221 is also fixedly provided with several elastic clamping blocks 222.

[0043] When in use, the metal pipe 10 to be processed is placed on the lower clamping plate 216, and then the second threaded rod 219 is driven to rotate by the third drive motor, so that the upper clamping plate 221 moves downward and clamps the metal pipe 10. The elastic clamping block 222 inside the upper clamping plate 221 fits against the metal pipe 10 to further clamp it. After the metal pipe 10 is clamped, the second drive motor 212 works to rotate the second connecting plate 214, which further realizes the rotation of the metal pipe 10. The first drive motor 225 can realize the back-and-forth movement of the metal pipe 10. In summary, the clamping mechanism 2 can realize the rotation and movement of the metal pipe 10, and together with other processes, it can realize the auxiliary processing of the metal pipe 10.

[0044] like Figure 3 As shown, the cutting mechanism 4 includes a third threaded rod 401 rotatably mounted on a crossbar on the mounting bracket 3. One end of the third threaded rod 401 is connected to a fourth drive motor 402, which is fixedly mounted on the mounting bracket 3. A second movable seat 403 is also slidably mounted on the mounting bracket 3. A first telescopic cylinder 404 is fixedly mounted on the second movable seat 403. A T-shaped plate 405 is fixedly mounted on the output end of the first telescopic cylinder 404. A cutting device 406 is fixedly mounted on the T-shaped plate 405. In use, the third threaded rod 401 is rotated by the fourth drive motor 402, thereby moving the second movable seat 403. The first telescopic cylinder 404 then moves the cutting device 406 up and down.

[0045] like Figure 3 As shown, an L-shaped rod 502 is also fixedly mounted on the second movable seat 403, and a mating sleeve 503 is also fixedly mounted on the L-shaped rod 502. A third connecting plate 501 is also fixedly mounted on the second movable seat 403, and a spring 505 is fixedly mounted on the third connecting plate 501. A rectangular rod 506 is fixedly connected to the other end of the spring 505. A limiting pressure plate 508 is fixedly mounted at the bottom end of the rectangular rod 506, and an L-shaped mating rod 507 is fixedly mounted at the side end of the rectangular rod 506. The L-shaped mating rod 507 can mate with the mating sleeve 503. An arc-shaped slot 509 is provided on the limiting pressure plate 508. Figure 4 As shown, a rectangular groove 510 is also provided on the rectangular rod 506, and a rectangular slide bar 504 is fixedly provided at the output end of the first telescopic cylinder 404. A rectangular slider 511 is also fixedly provided at one end of the rectangular slide bar 504, and the rectangular slider 511 is slidably disposed in the rectangular groove 510.

[0046] In use, the height of the limiting pressure plate 508 is lower than the height of the cutting device 406. When the first telescopic cylinder 404 extends, both the limiting pressure plate 508 and the cutting device 406 can move downwards simultaneously. However, the limiting pressure plate 508 first contacts the metal pipe 10, limiting the cutting end of the metal pipe 10. At this time, the L-shaped mating rod 507 is inserted into the mating sleeve 503, and the limiting pressure plate 508 stops moving downwards. The rectangular slider 511 also does not slide to the bottom of the rectangular groove 510. At this time, the first telescopic cylinder 404 continues to extend until the cutting device 406 contacts the metal pipe 10 to perform cutting. After cutting is completed, the first telescopic cylinder 404 retracts. The cutting device 406 is separated from the metal pipe 10. Under the action of the L-shaped mating rod 507 and the mating sleeve 503, the limiting pressure plate 508 is always in the limiting state. When the limiting pressure plate 508 needs to be retracted, the first telescopic cylinder 404 is controlled to retract. The rectangular slider 511 slides in the rectangular slide groove 510 until it slides to the top of the rectangular slide groove 510. Then the first telescopic cylinder 404 continues to retract, and the L-shaped mating rod 507 can be pulled out of the mating sleeve 503 under the pull of the rectangular slider 511, and finally the limiting pressure plate 508 is retracted. The spring 505 can also bring the rectangular slider 511 back to the initial position of the rectangular slide groove 510.

[0047] like Figure 5 As shown, the drilling mechanism 6 includes two first cylindrical slide rods 601 fixedly mounted on the base plate 1. A second horizontal top plate 602 is connected to the top of the two first cylindrical slide rods 601. A movable plate 603 slides on the two first cylindrical slide rods 601. A drilling device 604 is fixedly mounted on the movable plate 603. A fourth connecting plate 605 is also fixedly mounted on the drilling device 604. A first rack 606 is fixedly mounted on the fourth connecting plate 605. The drilling mechanism 6 also includes a fifth drive motor 608 fixedly mounted on the mounting bracket 3 via a short rod 607.

[0051] In use, the seventh drive motor 805 drives the eighth pulley 802 to rotate, and the seventh pulley 801 rotates via the fourth synchronous belt 803. The seventh pulley 801 then drives the first cylindrical shaft 808 to rotate.

Figure 9 As shown, when the metal short tube 11 in the arc groove 817 on the support platform 816 rotates to the large slide table 9, the cylindrical push rod 822 on the waist-shaped limiting groove 819 will tilt upwards and push the metal short tube 11 in the arc groove 817 outwards, fall to the large slide table 9, slide out and be collected.

[0052] A method for processing a hydraulic pipeline processing device includes the following steps:

[0053] S1: As Figure 10 As shown, the metal pipe 10 is first clamped and fixed by the clamping mechanism 2. Specifically, the metal pipe 10 is placed on the lower clamping plate 216. Then, by controlling the rotation of the second threaded rod 219, the upper clamping plate 221 moves downward until the elastic clamping block 222 on it contacts and presses against the metal pipe 10, thereby achieving the clamping and fixing of the metal pipe 10 by the upper clamping plate 221 and the lower clamping plate 216. The synchronous movement of the upper clamping plate 221 and the lower clamping plate 216 is achieved by the first threaded rod 206, so that the clamping mechanism 2 drives the metal pipe 10 to move forward until the metal pipe 10 is located in the arc groove 817 of the bearing platform 816.

[0054] S2: Subsequently, the cutting position of the cutting mechanism 4 is adjusted by the fourth drive motor 402, and the cutting device 406 and the limiting pressure plate 508 are controlled to move downward by the first telescopic cylinder 404. The height of the limiting pressure plate 508 is lower than the height of the cutting device 406. When the first telescopic cylinder 404 extends, the limiting pressure plate 508 and the cutting device 406 can move downward simultaneously. However, the limiting pressure plate 508 first contacts the metal pipe 10 to limit the cutting end of the metal pipe 10. At this time, the L-shaped mating rod 507 is inserted into the mating sleeve 503, limiting the pressure. When plate 508 stops moving downwards and rectangular slider 511 does not slide to the bottom of rectangular groove 510, the first telescopic cylinder 404 continues to extend until the cutting device 406 contacts the metal pipe 10. Then, the second drive motor 212 drives the upper clamping plate 221 and the lower clamping plate 216 to rotate, and the metal pipe 10 rotates accordingly to further achieve cutting. After cutting is completed, the first telescopic cylinder 404 retracts, and the cutting device 406 separates from the metal pipe 10. Under the action of L-shaped mating rod 507 and mating sleeve 503, the limiting pressure plate 508 is always in the limiting state.

[0055] S3: During the cutting process of the cutting mechanism 4, the drilling mechanism 6 descends to drill a hole at one end of the metal pipe 10. The inclined slide 707 and the arc-shaped polishing stone 708 on the waste collection mechanism 7 slide into the interior of the metal pipe 10. The debris generated by the drilling mechanism 6 falls through the hole 709 on the arc-shaped polishing stone 708 onto the inclined slide 707, and then slides down the inclined slide 707 into the rectangular trough 706, finally falling into the collection frame 704 for collection. When the arc-shaped polishing stone 708 moves into the interior of the metal pipe 10, it just contacts its interior. Firstly, it can support the drilling area during the drilling process to prevent the pipe from deforming. Secondly, it can clean the drilling area. The initial grinding process removes the small burrs produced by drilling. During the rotation of the metal pipe 10, the grinding block 818 also performs initial grinding on the outer wall of the metal pipe 10 after drilling, thus removing the small burrs on the outer wall of the metal pipe 10. The drilling mechanism 6 descends and the waste collection mechanism 7 moves synchronously. When the sixth drive motor 614 is working, it can drive the first gear and the second gear to rotate simultaneously. The first gear and the second gear mesh with the first rack and the second rack respectively, further realizing the downward movement of the drilling device 604, the movement of the arc-shaped grinding stone 708 and the inclined slide 707 into the metal pipe 10, and realizing the functions of drilling and waste collection.

[0056] S4: After cutting and drilling are completed, the metal short tube 11 after processing is rotated to the large slide table 9 by rotating the support table 816. At the same time, the cylindrical push rod 822 on the waist-shaped limiting groove 819 will tilt upward and push the metal short tube 11 in the arc groove 817 outward, fall to the large slide table 9, slide out and be collected.

A processing method for a water conservancy pipeline processing device, applied to the water conservancy pipeline processing device of claim 5, characterized in that, Includes the following steps: S1: First, the metal pipe (10) is clamped and fixed by the clamping mechanism (2). Specifically, the metal pipe (10) is placed on the lower clamping plate (216). Then, the upper clamping plate (221) is moved downward by controlling the rotation of the second threaded rod (219) until the upper elastic clamping block (222) contacts and presses against the metal pipe (10), thereby achieving the clamping and fixing of the metal pipe (10) by the upper clamping plate (221) and the lower clamping plate (216). The upper clamping plate (221) and the lower clamping plate (216) are moved synchronously by the first threaded rod (206), so that the clamping mechanism (2) drives the metal pipe (10) to move forward until the metal pipe (10) is located in the arc groove (817) of the bearing platform (816). S2: Subsequently, the cutting position of the cutting mechanism (4) is adjusted by the fourth drive motor (402), and the cutting device (406) and the limiting pressure plate (508) are controlled to move downward by the first telescopic cylinder (404). The height of the limiting pressure plate (508) is lower than the height of the cutting device (406). When the first telescopic cylinder (404) extends, the limiting pressure plate (508) and the cutting device (406) can move downward simultaneously. However, the limiting pressure plate (508) first contacts the metal pipe (10) and limits the cutting end of the metal pipe (10). At this time, the L-shaped mating rod (507) is inserted into the mating sleeve (503), and the limiting pressure plate... (508) Stop moving downwards, and the rectangular slider (511) does not slide to the bottom of the rectangular groove (510). At this time, the first telescopic cylinder (404) continues to extend until the cutting device (406) contacts the metal pipe (10). Then, the upper clamping plate (221) and the lower clamping plate (216) are driven to rotate by the second drive motor (212). The metal pipe (10) rotates accordingly to further achieve cutting. After the cutting is completed, the first telescopic cylinder (404) retracts and the cutting device (406) separates from the metal pipe (10). Under the action of the L-shaped mating rod (507) and the mating sleeve (503), the limiting pressure plate (508) is always in the limiting state. S3: During the cutting process of the cutting mechanism (4), the drilling mechanism (6) descends to drill a hole at one end of the metal pipe (10). The inclined slide (707) and the arc-shaped grinding stone (708) on the waste collection mechanism (7) slide into the interior of the metal pipe (10). The debris generated by the drilling mechanism (6) falls onto the inclined slide (707) through the hole (709) on the arc-shaped grinding stone (708), and then slides down into the rectangular trough (706) through the inclined slide (707), and finally falls into the collection frame (704) for collection.

Firstly, it can support the drilling area during the drilling process to prevent the pipe from deforming. Secondly, it can perform preliminary grinding on the interior of the drilling area to make the drilling process smoother. The small burrs generated are removed by grinding. During the rotation of the metal pipe (10), the grinding block (818) will also perform preliminary grinding on the outer wall of the metal pipe (10) after drilling, so as to remove the small burrs on the outer wall of the metal pipe (10). The drilling mechanism (6) descends and the waste collection mechanism (7) moves synchronously. When the sixth drive motor (614) works, it can drive the first gear (615) and the second gear (616) to rotate at the same time. The first gear (615) and the second gear (616) mesh with the first rack (606) and the second rack (712) respectively, so as to further realize the downward movement of the drilling device (604), the arc-shaped grinding stone (708) and the inclined slide (707) into the metal pipe (10), and realize the drilling and waste collection functions. S4: After cutting and drilling, the metal short tube (11) after processing is rotated to the large slide table (9) by rotating the support table (816). At the same time, the cylindrical push rod (822) on the waist-shaped limiting groove (819) will tilt and move upward, pushing the metal short tube (11) in the arc groove (817) outward, falling to the large slide table (9), and sliding out for collection.
