Description

Technical Field

[0001] This application relates to the field of corrugated pipe manufacturing technology, and in particular to a pipe end trimming device for corrugated pipe manufacturing. Background Technology

[0002] Corrugated pipes, as a commonly used pipe component, are widely used in construction, water conservancy, chemical and other fields. During the production process, the ends of corrugated pipes often have defects such as burrs and unevenness, which need to be repaired to ensure connection accuracy. At the construction site, corrugated pipes are often deformed or damaged at the pipe ends due to transportation collisions, improper installation operations or environmental factors, such as end dents, thread wear, and end face misalignment. Direct replacement would increase costs and affect the construction progress. In the existing technology, the production equipment and repair equipment are separated, and the following common problems are generally present.

[0003] For example, Chinese utility model patent No. 2021225569318, entitled "A Corrugated Pipe Flattening Device," uses a rotating shaft to drive a pressure roller to flatten the end of the corrugated pipe. However, the fixed fit between the pressure roller and the guide rail is only suitable for standard pipe diameters and cannot dynamically match the deformed pipe contour. Moreover, it can only perform flattening operations and cannot perform diverse repair tasks such as cutting, grinding, and reshaping. Furthermore, it lacks a linkage design with the support mechanism, making it difficult to deploy quickly on the construction site. Another example is patent No. 2021227339787, entitled "An End Face Grinding Device for Stainless Steel Corrugated Pipe Processing," which uses a grinding strip to adhere to the corrugated pipe protrusion for end face processing. However, the position of the grinding strip is fixed, and the grinding depth cannot be dynamically adjusted according to the degree of pipe deformation. In addition, it can only process the outer wall of the pipe and lacks an inner wall support structure, which makes the pipe prone to shaking during the repair process.

[0004] For the reasons mentioned above, this invention proposes a pipe end trimming device for corrugated pipe production to solve the above problems. Summary of the Invention

[0037] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0038] A pipe end trimming device for corrugated pipe production includes an inner support shell 1, an end processing mechanism 2 for processing the ends of the corrugated pipe is provided on the inner support shell 1 via a rotation and telescopic mechanism, and an adjustment support mechanism 3 is provided inside the inner support shell 1 to adjust the support according to the specifications of the corrugated pipe.

[0039] The rotating telescopic mechanism is located at the end of the inner support housing 1 and includes a rotating motor and a hydraulic cylinder. The hydraulic cylinder is located on the inner support housing, and the rotating motor is located on the output end of the hydraulic cylinder. The output shaft of the rotating motor is connected to the mounting housing 21 and can control the end processing mechanism to rotate 360°. The hydraulic cylinder can drive the mounting housing to extend and retract axially.

[0040] The end processing mechanism 2 includes a mounting housing 21 mounted on a rotary telescopic mechanism. The mounting housing 21 is uniformly provided with an execution component 22 for processing the end of the bellows along its circumference. The execution component 22 can slide relative to the mounting housing 21 and has an execution position for trimming the end of the bellows and a rest position within its stroke. The mounting housing 21 is provided with a drive component 23 for controlling the movement of the execution component 22.

[0041] According to the specifications of the corrugated pipe fitting, the drive assembly 23 drives the execution assembly 22 to move, realizing the switching of its work position; at the same time, the positioning component in the drive assembly can accurately lock the execution assembly 22, ensuring that the execution assembly 22 is stable in position during processing, avoiding displacement due to force or vibration, and providing power and positioning guarantee for the stable processing of the execution assembly 22. Driven by the drive assembly 23, the execution assembly 22 can switch between the resting work position and the execution work position; after reaching the execution work position, through the internal and external coordinated processing structure, different processing functions such as cutting, grinding, and shaping are switched according to the needs to repair or modify the inner and outer walls and end faces of the corrugated pipe to adapt to pipes of different specifications and deformation conditions.

[0042] The drive assembly 23 includes a control frame 231 slidably disposed on the inner wall of the mounting housing 21. A first electric slider 232 for driving the control frame 231 to rotate is disposed on the inner wall of the mounting housing 21. The first electric slider 232 is connected to the control frame 231. A control groove 236 is provided on the control frame 231. One end of the execution block 221 located inside the mounting housing 21 is slidably disposed in the control groove 236. Linkage holes are evenly provided on the execution block 221 along its length direction. A positioning component is provided inside the mounting housing 21.

[0043] Using the above scheme, when the first electric slider 232 drives the control frame 231 to rotate, the control slide 236 pushes the execution block 221 to slide along the execution groove 223 on the mounting housing 21 through the inclined guide action. When the execution block 221 extends outward to contact the end of the bellows, the execution component 22 moves to the execution position.

[0044] To ensure that the execution component 22 does not shift during processing, the positioning component of the drive component 23 cooperates with the execution component 22 to achieve rigid positioning of the execution component 22. The positioning component includes a positioning cylinder 233 installed in the mounting housing 21, a positioning frame 234 installed on the positioning cylinder 233, a positioning rod 235 that cooperates with the linkage hole installed on the positioning frame 234, and through holes that cooperate with the linkage hole evenly installed on the control frame 231.

[0045] Using the above technical solution, during operation, the positioning cylinder 233 drives the positioning frame 234 to move, and the positioning rod 235 on the positioning frame 234 passes through the through hole and the linkage hole of the execution block 221 in sequence. Through the mutual cooperation between the positioning rod 235, the through hole and the linkage hole, the position of the control frame 231 and the execution block 221 is locked, thereby realizing the rigid positioning of the positioning component 22 at the execution position.

[0046] The execution component 22 includes an execution groove 223 formed on the mounting housing 21. An execution work block 221 is slidably disposed in the execution groove 223. The execution work block 221 is connected to the drive component 23. An internal processing block 222 for fitting against the inner wall of the bellows is provided on the execution work block 221. An installation groove 224 is formed on the internal processing block 222. An end face processing component 24 for trimming the end face of the bellows is provided on the execution work block 221. The end face processing component 24 is located in the installation groove 224. An external processing component 25 for trimming the outside of the bellows is provided on the internal processing block 222. The external processing component 25 is located behind the end face processing component 24. An adjustment control 26 for controlling the external processing component 25 is provided on the end face of the mounting housing 21 away from the drive component 23.

[0047] By adopting the above technical solution, when the execution component 22 is in the execution position, the internal processing block 222 is attached to the inner wall of the bellows. The surface of the internal processing block 222 is provided with a rubber layer. During operation, the rubber layer increases the adhesion between the internal processing block 222 and the inner wall of the bellows. At the same time, the rubber layer can protect the inner wall of the bellows from scratches. At this time, depending on the bellows repair situation, if the inner and outer walls of the bellows are deformed and need to be repaired, the external processing component 25 is attached to the outer wall of the bellows under the action of the adjustment control 26. The repair operation of the deformed bellows is completed through the cooperation between the rotation telescopic mechanism, the external processing component 25 and the internal processing block 222. If the end face of the bellows needs to be processed, the drive component 23 controls the execution component 22 to leave the execution position. In this state, the internal processing block 222 is not in contact with the inner wall of the bellows. At this time, the end face processing component 24 works, adjusts the corresponding processing mode, and completes the repair operation of the end face of the bellows with the cooperation of the rotation telescopic mechanism.

[0048] The end face processing component 24 includes a conversion motor 241 mounted on the execution block 221, a mounting plate 242 mounted on the conversion motor 241, a processing frame 243 mounted on the circumferential end face of the mounting plate 242, and the processing frame 243 is distributed on the mounting plate 242 in an arc shape. The processing frame 243 is provided with a processing block for processing the end face of the corrugated pipe, and a bonding plate 244 is provided on the mounting plate 242, the bonding plate 244 having an arc structure.

[0049] Different processing racks 243 are equipped with tools for cutting, grinding, and straightening the end face of the corrugated pipe, which are mounted on bolts respectively. During operation, according to the trimming requirements of the corrugated pipe end face, the conversion motor 241 is started to drive the mounting plate 242 to rotate, which drives the corresponding end face processing tool to switch to the working position. At this time, the other tools and the bonding plate 244 do not interfere with the operation of the tool in this working position.

[0050] The rotary telescopic mechanism operates in this state, controlling the end face processing tool on the processing frame 243 to rotate and feed towards the end face of the bellows during movement, thereby completing the cutting, grinding, or straightening operation of the bellows end face.

[0051] When external processing component 25 is required to perform operations, the conversion motor 241 synchronously drives the bonding plate 244 to switch to the working position to cooperate with the external processing component 25 to complete the collaborative operation.

[0052] The execution block 221 has an assembly groove that communicates with the linkage hole, and the execution block 221 has a limit hole on the end face away from the linkage hole. The mounting plate 242 has locking holes 246 that cooperate with the limit hole evenly distributed along its circumference. An assembly spring rod 225 is provided in the assembly groove. A locking plate 226 is provided on the assembly spring rod 225. A locking rod 227 is provided on the locking plate 226. A locking rod 228 is slidably provided in the limit hole. The locking rod 228 is a telescopic structure.

[0053] When the positioning component is activated, the positioning rod 235 first inserts into the linkage hole of the execution block 221. Through precise cooperation with the linkage hole, it completes the initial locking of the execution block 221 and the control frame 231, laying a stable foundation for subsequent operations.

[0054] If it is necessary to lock the mounting plate 242 to ensure the end face processing accuracy, the positioning cylinder 233 will drive the positioning rod 235 to continue to move into the linkage hole. During this process, the positioning rod 235 presses the locking plate 226, causing the locking plate 226 to simultaneously drive the locking rod 1 227 and the locking rod 228 to move. The locking rod 228 is precisely inserted into the locking hole 246 of the mounting plate 242, realizing the rigid locking of the mounting plate 242 and ensuring that the end face processing tool has no displacement deviation during operation. At this time, the locking rod 1 227 is just embedded in the through hole on the other end face of the control frame 231.

[0055] When the external processing component 25 needs to participate in the operation, the composite locking process is initiated: First, the positioning cylinder 233 drives the positioning rod 235 back to the state of locking only the execution block 221 and the control frame 231; Second, the conversion motor 241 drives the bonding plate 244 to rotate to the working position; Third, the positioning cylinder 233 pushes the positioning rod 235 to advance its movement again, and through the transmission of the locking plate 226, the locking rod 227 passes through the through hole of the control frame 231 and finally inserts into the locking hole of the connecting frame 254, thus completing the locking of the external processing block 252. During this process, the locking plate 226 simultaneously drives the locking rod 228 to be inserted into the locking hole, and when the locking rod 227 enters the locking hole, the locking rod 228 is in a compressed state in the locking hole, so that the mounting plate 242, the connecting frame 254, the execution block 221 and the control frame 231 form a multi-dimensional coordinated locking.

[0056] The external processing component 25 includes guide holes symmetrically opened on the internal processing block 222. A guide rod 251 is slidably arranged in the guide holes. An external processing block 252 is arranged on the guide rod 251. A spring is sleeved on the guide rod 251, which is located between the external processing block 252 and the internal processing block 222. An auxiliary groove 253 is opened on the external processing block 252 to cooperate with the bonding plate 244. When the external processing block 252 moves toward the corrugated pipe, the bonding plate 244 can pass through the auxiliary groove 253, which can improve the stability during operation. The end of the guide rod 251 away from the external processing block 252 is connected through a connecting frame 254. The connecting frame 254 is connected to the adjustment control 26. The external processing block 252 has a moving groove. A moving block 255 is slidably arranged in the moving groove. An auxiliary ball is arranged on the end face of the moving block 255 facing the internal processing block 222. A moving spring 256 is arranged between the moving block 255 and the moving groove.

[0057] The processing rack 243 is provided with a card block 245, and the external processing block 252 is provided with a card slot 257 that cooperates with the card block 45;

[0058] Once the corresponding tool processing rack 243 is selected, the adjustment control 26 drives the external processing block 252 to move downward, causing the card block 245 to be inserted into the card slot 257, thereby further improving the stability of the processing tool operation on the upper surface of the processing rack 243.

[0059] The control unit 26 includes a control motor 261 disposed inside the mounting housing 21. A control plate 262 is disposed on the output shaft of the control motor 261. A connecting rod 263 is hinged between the control plate 262 and the connecting frame 254. The connecting frame 254 is attached to the control frame 231, and a locking hole that cooperates with the through hole is provided on the connecting frame 254.

[0060] When the outer wall of the bellows needs to be repaired during operation using the above technical solution, the internal processing block 222 is adjusted to the execution position, and the control motor 261 is started to control the control plate 262 to rotate. During this process, the external processing block 252 moves toward the outer wall of the bellows through the cooperation between the connecting rod 263 and the connecting frame 254, so that the auxiliary ball on the moving block 255 can fit into the thread gap of the outer wall of the bellows. The rotating telescopic mechanism drives the mounting housing 21 to rotate. During the rotation, the mounting housing 21 synchronously drives the internal processing block 222 and the external processing block 252 to rotate along the bellows. The rotating internal processing block 222 repairs the deformed bellows, while the auxiliary ball on the moving block 255 moves and repairs the outer wall of the bellows by following the thread gap of the bellows. The repair of the deformed inner and outer walls of the bellows is completed by the synchronous rotation and repair of the internal support and the external fit.

[0061] The adjusting support mechanism 3 includes support holes evenly opened around the circumference of the inner support shell 1. A support frame 31 is slidably arranged in the support holes. A support block 38 is arranged on the support frame 31. A second electric slider 32 with an annular structure is arranged inside the inner support shell 1. A threaded disc 33 is arranged on the second electric slider 32. A threaded block is arranged on one end of the support frame 31 near the threaded disc 33. The threaded block meshes with the threaded disc 33. A limiting component is arranged on the inner support shell 1. The limiting component is used to limit the support frame 31.

[0062] The limiting component includes a limiting cylinder 34 disposed on the inner wall of the inner support shell 1. A limiting moving frame 35 is disposed on the limiting cylinder 34. A limiting partition 36 is disposed on the inner support shell 1. The limiting partition 36 is located between the limiting moving frame 35 and the support frame 31. Fixing holes are evenly opened on the support frame 31 along its length direction. A through hole that cooperates with the fixing holes is opened on the limiting partition 36. A fixing rod 37 is disposed on the limiting moving frame 35. The fixing rod 37 is movably disposed in the through hole.

[0063] By adopting the above technical solution, the inner support shell is inserted into the bellows during operation. Then, the second electric slider 32 is activated to drive the threaded disc 33 to rotate. The interaction between the threaded disc 33, the threaded block, and the support hole drives the support block 38 to move toward the inner wall of the bellows. Rubber particles are provided on the outer wall of the support block 38 to increase the friction between it and the inner wall of the bellows, thereby improving the stability of the inner support shell 1 in the bellows. After the inner support shell 1 is fixed in the inner wall of the bellows, the limit cylinder 34 is activated to drive the fixing rod 37 through the through hole and into the fixing hole, thereby locking the support frame 31.

[0064] In this invention, the inner support shell 1 is adaptively fixed by adjusting the support mechanism 3, the support frame 31 extends under the drive of the threaded disc 33, and the support block 38 fits the inner wall of the bellows of different specifications and shapes, and is locked with the limiting component to ensure overall stability.

[0065] The end processing mechanism 2 and the drive component 23 achieve the switching of the execution component 22 between the rest position and the execution position through the sliding cooperation between the control frame 231 and the execution block 221. The positioning rod 235 of the positioning component locks the execution block 221, the mounting plate 242 and the connecting frame 254 of the external processing component 25 to ensure that there is no displacement during the processing.

[0066] The end face processing component 24 switches between different processing frames 243 via the conversion motor 241, and completes the end face processing in conjunction with the rotational feed of the rotary telescopic mechanism; the external processing component 25, driven by the adjustment control 26, uses an auxiliary ball to fit the outer wall thread gap, and works in conjunction with the internal processing block 222 to synchronously repair the inner and outer contours during rotation.

[0067] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
