Description

Technical Field

[0001] This invention relates to the field of corrugated pipe production equipment technology, and in particular to a power corrugated pipe corrugating forming module that can be quickly changed. Background Technology

[0002] Corrugated pipes are a new type of lightweight pipe made from high-density polyethylene. They are characterized by light weight, high pressure resistance, good toughness, fast construction, and long service life. Their excellent pipe wall structure design significantly reduces costs compared to other pipe structures.

[0003] In existing corrugated pipe forming processes, two sets of molds are typically used. These molds are mounted on two rotary conveyor mechanisms. When the molds on both conveyor mechanisms are positioned close to each other, they cooperate to form a forming cavity. When the molds move to the discharge end of the conveyor mechanism, they move away from each other, allowing the formed corrugated pipe to proceed to the next process. When the two molds on the conveyor mechanism move to the feed end, they approach each other and cooperate to form a forming cavity.

[0004] Molds are typically integral structures, fixed to the moving parts of a conveyor mechanism, such as belt-type moving parts. The mold can be secured to the belt-type moving parts using fasteners such as bolts.

[0005] Because the forming cavity requires two molds with high positional accuracy, and the molds are fixed on the conveying mechanism, when producing corrugated pipes of different specifications, the integral mold needs to be removed from the conveying mechanism and replaced with a new mold. The mold replacement process is inconvenient and the accuracy of repeated mold installation is low.

[0006] Therefore, the existing corrugated pipe forming molds have the technical problem of being difficult to replace. Summary of the Invention

[0007] The present invention provides a quick-change power corrugated pipe corrugated forming module, which solves the technical problem that the corrugated pipe forming mold is not easy to replace in the prior art.

[0008] Some implementation schemes for solving the above-mentioned technical problems include: A quick-change power corrugated pipe corrugating forming module, including a fixing base; A mold, wherein the mold is disposed on the fixed base; and a locking assembly, the locking assembly being used to lock the mold to the fixed base; The locking assembly includes a locking shaft disposed on the mold, the locking shaft being provided with a locking groove, the locking groove being annularly disposed on the locking shaft, and the cross-sectional shape of the locking groove being V-shaped; The locking assembly further includes a locking block disposed on the fixed base. The locking block is slidably connected to the fixed base, and the locking block is slidably connected to the fixed base along the diameter direction of the locking shaft. An elastic element is disposed between the locking block and the fixed base to push the locking block so that a portion of the locking block extends into the locking groove to position the mold. The locking shaft has an inclined surface at the end away from the mold, which overcomes the force of the elastic element and causes the locking block to move away from the locking shaft when the mold is assembled with the fixed base. The fixed base has a through hole through which the locking shaft passes. An anti-rotation device is provided between the mold and the fixed base to prevent the mold from rotating relative to the fixed base.

[0009] Preferably, the locking shaft and the mold are an integral structure, and there are at least two locking blocks, which are evenly distributed along the circumference of the locking shaft.

[0010] Preferably, the locking block includes a mating part that mates with the locking groove and a guide part disposed on the mating part. One end of the elastic element contacts the guide part. The mating part has a V-shaped cross-section. The mating part and the guide part are an integral structure. The fixing seat is provided with a guide groove that mates with the guide part. The through hole communicates with the guide groove.

[0011] Preferably, the guide part is further provided with a guide post, and the fixing seat is provided with a guide hole that cooperates with the guide post. The guide post and the cooperating part are an integral structure, and the guide hole communicates with the guide groove.

[0012] Preferably, the elastic element is sleeved on the guide post, the elastic element is a spring, one end of the elastic element contacts the inner wall of the guide groove, and the other end of the elastic element contacts the guide portion.

[0013] Preferably, the width of the guide portion is greater than the width of the mating portion, and the distances from both sides of the mating portion to both sides of the guide portion are equal.

[0014] Preferably, the cross-sectional shape of the mating part is cuboid, and there are multiple guide posts that are evenly arranged along the length of the mating part. Each guide post is fitted with an independent elastic element.

[0015] Preferably, the anti-rotation device includes an anti-rotation post disposed in the mold, and the anti-rotation device also includes an anti-rotation hole disposed in the fixed base, the anti-rotation post cooperating with the anti-rotation hole.

[0016] Preferably, there are multiple anti-rotation pins, which are located on both sides of the locking shaft. Each anti-rotation pin is matched with an independent anti-rotation hole, and the number of anti-rotation pins located on both sides of the locking shaft is not equal.

[0017] Preferably, the mold is further provided with a positioning protrusion, the positioning protrusion is hemispherical in shape, the positioning protrusion and the mold are integrally formed, and another mold that cooperates with the mold provided with the positioning protrusion to form a forming cavity is provided with a positioning groove that cooperates with the positioning protrusion; the fixing seat is provided with a mounting groove for fixing the fixing seat to the conveying mechanism.

[0018] Compared with the prior art, the present invention has the following advantages: The mold can be quickly locked and unlocked by setting up a locking assembly. The annular V-shaped locking groove on the locking shaft cooperates with the locking block. When the mold is installed on the fixed base, the locking shaft passes through the through hole of the fixed base. The inclined surface at one end of the locking shaft overcomes the force of the elastic element, causing the locking block to move away from the locking shaft. After the mold is installed in place, the elastic element pushes the locking block, causing a part of it to extend into the locking groove, thereby accurately positioning and locking the mold on the fixed base. This design makes the installation and disassembly of the mold very simple. The mold can be quickly changed by simply pushing in and pulling out, which greatly shortens the changeover time and improves production efficiency.

[0019] Compared to integral molds that are directly fixed to the moving parts of the conveying mechanism, changing molds requires removing the integral mold from the conveying mechanism and then installing a new mold, which is inconvenient and results in low accuracy with repeated installations. This quick-change module overcomes these drawbacks because the fixing base does not need to be removed from the conveying mechanism. It eliminates the need for complex disassembly and installation processes, reducing the time and difficulty of manual operation, while improving the accuracy and stability of mold changes and ensuring the production quality of corrugated pipes of different specifications.

[0020] The anti-rotation device installed between the mold and the fixed base effectively prevents the mold from rotating relative to the fixed base. During the bellows forming process, the mold needs to maintain a stable position and orientation to ensure the accuracy of the forming cavity and the forming quality of the bellows. If the mold rotates, the shape of the forming cavity will change, thus affecting the dimensional accuracy and performance of the bellows. The presence of the anti-rotation device ensures the stability of the mold during the forming process, avoids quality problems caused by mold rotation, and improves the product yield.

[0021] This quick-change power corrugated pipe corrugating module improves production efficiency, reduces production costs, and enhances product quality through its rapid changeover and mold-prevention design. It can quickly adapt to the production needs of corrugated pipes of different specifications, reducing equipment downtime and mold replacement costs, while ensuring product stability and consistency, providing a more efficient and reliable solution for corrugated pipe production.

[0033] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0034] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0035] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] Reference Figures 1 to 6 As shown, a quick-change power corrugated pipe corrugating forming module includes a fixing base 1; Mold 2, wherein the mold 2 is disposed on the fixed base 1; and locking assembly 3, the locking assembly 3 being used to lock the mold 2 to the fixed base 1; The locking assembly 3 includes a locking shaft 21 disposed on the mold 2. The locking shaft 21 is provided with a locking groove 211. The locking groove 211 is arranged in a ring shape on the locking shaft 21, and the cross-sectional shape of the locking groove 211 is V-shaped. The locking assembly 3 further includes a locking block 31 disposed on the fixed base 1. The locking block 31 is slidably connected to the fixed base 1, and the locking block 31 is slidably connected to the fixed base 1 along the diameter direction of the locking shaft 21. An elastic member 32 is disposed between the locking block 31 and the fixed base 1 to push the locking block 31 so that a part of the locking block 31 extends into the locking groove 211 to position the mold 2. The locking shaft 21 has an inclined surface 212 at the end away from the mold 2, which overcomes the force of the elastic element 32 when the mold 2 is assembled with the fixed base 1, causing the locking block 31 to move away from the locking shaft 21. The fixed base 1 has a through hole 11 through which the locking shaft 21 passes. An anti-rotation device 4 is provided between the mold 2 and the fixed base 1 to prevent the mold 2 from rotating relative to the fixed base 1.

[0037] Understandably, the fixed base 1 is fixed to the moving part of the conveying mechanism, and the fixed base 1 can be fixed to the moving part of the conveying mechanism in any way. When changing molds 2 of different specifications, the fixed base 1 does not need to be removed, thereby improving the positional accuracy of the mold 2 after multiple assembly and disassembly.

[0038] The conveying mechanism is usually a rotary conveying mechanism, such as a belt conveyor, etc.

[0039] Reference Figures 3 to 6 As shown, in some embodiments, to improve the positioning accuracy of the mold 2 relative to the fixed base 1, the locking shaft 21 and the mold 2 are integrally formed, and there are at least two locking blocks 31, which are evenly distributed along the circumference of the locking shaft 21. Because the locking shaft 21 and the mold 2 are integrally formed, the position of the locking shaft 21 relative to the mold 2 does not change, thereby improving the positional accuracy of the locking shaft 21 relative to the mold 2. The locking shaft 21 cooperates with the through hole 11, further improving the positioning accuracy of the mold 2 relative to the fixed base 1. The more locking blocks 31 there are, the better the locking performance of the locking assembly 3.

[0040] Understandably, since molds 2 are used in pairs to form molding cavities, the force exerted on molds 2 in actual applications is not large. The locking requirements of molds 2 are fully met by using locking block 31 in conjunction with locking groove 211.

[0041] In some embodiments, the locking block 31 includes a mating portion 311 that mates with the locking groove 211 and a guide portion 312 disposed on the mating portion 311. One end of the elastic member 32 contacts the guide portion 312. The mating portion 311 has a V-shaped cross-section. The mating portion 311 and the guide portion 312 are integrally formed. The fixing base 1 is provided with a guide groove 12 that mates with the guide portion 312. The through hole 11 communicates with the guide groove 12. The guide portion 312 guides the mating portion 311, enabling the mating portion 311 to have higher positional accuracy relative to the fixing base 1.

[0042] Reference Figures 3 to 6 As shown, in some embodiments, the guide portion 312 is further provided with a guide post 33, and the fixed base 1 is provided with a guide hole 13 that mates with the guide post 33. The guide post 33 and the mating portion 311 are an integral structure, and the guide hole 13 communicates with the guide groove 12. The guide post 33 and the guide portion 312 jointly guide the mating portion 311, improving the movement accuracy of the mating portion 311.

[0043] In some embodiments, the elastic element 32 is sleeved on the guide post 33. The elastic element 32 is a spring. One end of the elastic element 32 contacts the inner wall of the guide groove 12, and the other end of the elastic element 32 contacts the guide portion 312. In addition to guiding the guide portion 312, the guide post 33 also guides the elastic element 32 to prevent the elastic element 32 from bending during long-term use.

[0044] In some embodiments, the width of the guide portion 312 is greater than the width of the mating portion 311, and the distances from both sides of the mating portion 311 to both sides of the guide portion 312 are equal. Because the width of the guide portion 312 is greater than the width of the mating portion, the mating portion 311 will not contact the sidewall of the guide groove 12, thereby reducing wear on the mating portion 311 and improving the locking accuracy of the locking assembly 3.

[0045] In some embodiments, the cross-sectional shape of the mating part is cuboid, and there are multiple guide posts 33. The multiple guide posts 33 are evenly arranged along the length direction of the mating part 311, and each guide post 33 is fitted with an independent elastic element 32.

[0046] Reference Figures 4 to 5 As shown, in some embodiments, the anti-rotation device 4 includes an anti-rotation post 41 disposed on the mold 2, and the anti-rotation device 4 also includes an anti-rotation hole 42 disposed on the fixed base 1, wherein the anti-rotation post 41 cooperates with the anti-rotation hole 42.

[0047] In some embodiments, there are multiple anti-rotation pins 41, which are located on both sides of the locking shaft 21. Each anti-rotation pin 41 is engaged with an independent anti-rotation hole 42, and the number of anti-rotation pins 41 located on both sides of the locking shaft 21 is not equal.

[0048] Understandably, when mold 2 forms spiral corrugations, each mold 2 has a specific position and orientation, that is, the upper end of mold 2 and the lower end of mold 2 cannot be installed in reverse. By making the number of anti-rotation pins 41 on both sides of locking shaft 21 unequal, it is possible to effectively prevent mold 2 from being installed in reverse.

[0049] Reference Figure 1 As shown, in some embodiments, the mold 2 is further provided with a positioning protrusion 22, the positioning protrusion 22 is hemispherical in shape, the positioning protrusion 22 and the mold 2 are integral structures, and another mold 2 that cooperates with the mold 2 provided with the positioning protrusion 22 to form a molding cavity is provided with a positioning groove that cooperates with the positioning protrusion 22; the fixing seat 1 is provided with an installation groove for fixing the fixing seat 1 to the conveying mechanism.

[0050] Understandably, taking a belt conveyor as an example, the mounting slot can be attached to the conveyor belt of the belt conveyor and then fixed to the conveyor belt in any way.

[0051] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.

[0052] Furthermore, in some embodiments of the above invention, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine and implement the above embodiments according to their needs to obtain a better application experience.

[0053] When implementing the subject matter of this invention, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter and drawings. Obviously, these details are still within the scope of the subject matter of this invention without departing from it.
