Description

Technical Field

[0001] The invention relates to the technical field of nylon pipes, in particular to a steel skeleton reinforced nylon pipe prefabrication forming mechanism and a quality control method. Background Art

[0002] Liquid pipeline transportation and material transportation of different media have spread throughout the power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and are developing rapidly. When conveying abrasive materials (such as ash, coal powder, mineral concentrate, tailings, cement, etc.) in the pipeline, there is a problem of rapid pipe wear. In particular, elbows wear faster. When conveying highly corrosive gases, liquids and solids in the pipeline, there is a problem of rapid pipeline damage due to corrosion.

[0003] On June 18, 1997, China Patent (Classification No. B29C39 / 08) announced a method for manufacturing an anti-corrosion pipeline reinforced MC nylon pipeline. It is made of caprolactam as raw material, heated in a melter and subjected to vacuum treatment, then additives are added to react under homogenization treatment, and then poured into a mold for centrifugal casting and polymerization. On October 19, 1999, China Patent CN1293330 announced a method for manufacturing a large-diameter metal nylon composite pipe. It is characterized in that a metal frame is embedded between the walls of the nylon pipe. It is made of modified nylon material with good impact resistance as the main material, and is added with an appropriate amount of co-catalyst, coupling agent and stabilizer, and a certain proportion of glass fiber and filler. On January 9, 2008, China Patent Utility Model Patent CN200720118173.9 (Classification No. F16L11 / 10; B32B1 / 08) announced a method for manufacturing a wire mesh reinforced composite fluoroplastic pipe. It is a wire mesh reinforced composite fluoroplastic pipe, including a fluoroplastic pipe preform. The wire mesh reinforced composite fluoro and thermal insulation properties enhance the working pressure that the composite fluoroplastic pipe can withstand and extend its service life. These pipes have problems to varying degrees, such as poor density and loose bonding between metal structural parts and the mother material of the pipe, which results in the pipes not meeting the requirements for impact resistance, corrosion resistance, aging resistance and thermal expansion and contraction resistance in actual use; the pipe joints are not easy to seal, are prone to corrosion and leakage; and such products are affected by the external environment and the conveying medium during actual application, resulting in large thermal expansion and contraction, causing creep and failure; At present, the pipes actually used in the field of material transportation are mostly complicated in production and manufacturing process, long in production and manufacturing cycle, pollution is generated in the manufacturing process, the raw material price is high, it is not easy to install, maintenance is difficult, and maintenance costs are high, so the actual application effect is difficult to meet the ideal design requirements.

[0004] Nylon pipes have gradually replaced steel pipes and are widely used in pipelines in many industries such as electricity, metallurgy, coal, petroleum, chemical industry, building materials, machinery, etc. due to their strong resistance to high and low temperatures, excellent corrosion resistance and wear resistance, as well as their advantages of easy installation and high transportation efficiency. However, since each unit pipe that makes up the pipeline is generally more than ten meters long, and nylon is a plastic material, the pipeline is relatively flexible and lacks rigidity. Especially when transporting materials with a large specific gravity, the pipeline's ability to resist internal pressure is significantly weak, its strength is poor, and its deformation is serious. In order to solve the above problems, people have enhanced the pipeline's pressure resistance and extended its service life by embedding metal frames or wire mesh in the nylon pipe wall. The rebar is woven into a metal skeleton in the shape of a warp and weft mesh tube and embedded in the middle of the nylon tube. The nylon polymer is coated on the metal skeleton of the rebar. Such nylon pipes not only have the advantages of stable chemical properties, acid and alkali resistance, low temperature resistance, corrosion resistance, and aging resistance, but also have the characteristics of close integration of the steel skeleton and the pipe matrix material, high density, strong impact resistance, high internal pressure resistance, and strong ability to resist deformation. Therefore, they are favored and expected by many users.

[0005] The existing preparation process of steel skeleton reinforced nylon pipe is generally to use the braiding mechanism of the pipe manufacturing machine to braid the steel skeleton warp and weft into a mesh steel skeleton in the mold cavity, and then extrude the nylon slurry to the outside of the steel skeleton for coating. However, during the coating, the embedding depth of the steel skeleton is not easy to control. During the use of the pipe, the internal fluid scours the inner wall of the pipe. If the embedding depth is too low, the steel skeleton is easily exposed on the inner wall of the pipe, and the steel skeleton mesh is coated too deeply, causing the inner wall of the pipe to crack easily. Therefore, a technology is needed that can conveniently control the embedding depth of the steel skeleton when the pipe is prepared and formed. Summary of the invention

[0006] The present invention controls quality by changing the exposed thickness of the steel pipe rack. When the pipeline is in use, the internal fluid scours the inner wall of the pipeline, and at the same time, the steel skeleton net is prevented from being covered too deeply, which may cause the inner wall of the pipeline to crack easily.

Two third cylinders 28 are connected in series, and the scale bar 29 is used to measure the distance between the two clamping rods 25 and the clamping block 26, so as to quickly display the inner diameter of the fixed steel frame fixing tube 1.

[0029] After the servo motor 22 is turned on, it drives the screw rod 21 to rotate, and then the sliding plate 20 threadedly connected to the screw rod 21 moves back and forth along the slide groove 19 under different rotation directions of the servo motor 22. When the sliding plate 20 moves, it drives the fixed plate 23 to move left and right.

[0030] In this embodiment, the rotating disk 24 can completely cover the end surface of the pipe casting cavity to prevent the nylon slurry from flowing out during casting, and at the same time, combined with the sealing of the other end of the pipe casting cavity, a complete pipe casting is formed.

[0031] At the same time, the movement of two clamping rods 25 is controlled by the third cylinder 28. After the steel frame fixing tube 1 is placed, the third cylinder 28 can be opened to drive the clamping rod 25 to move toward the axis of the steel frame fixing tube 1. The servo motor 22 is turned on again to take out the clamping rod 25 independently.

[0032] A replacement and adjustment component is provided on the side of the fixed plate 2, specifically, a cross bar 30 is rotatably connected inside the rotating seat 4, a connecting rod 31 is fixed on the side of the cross bar 30, a rotating shaft 32 is fixed to the end of the connecting rod 31 away from the cross bar 30, the rotating shaft 32 is rotatably connected to the placement plate 5, and an expansion block 33 for rotatably connecting the rotating shaft 32 is integrated at the bottom of the placement plate 5, the expansion block 33 extends along the length direction of the placement plate 5, and a plurality of connecting rods 31 are provided along the circumferential direction of the cross bar 30.

At the same time, in this embodiment, the placement plate 5 is semicircular in shape, and the outer wall is higher than the center of the placement plate 5. Therefore, the steel frame fixing cylinder 1 placed therein rotates simultaneously with the connecting rod 31 under the action of gravity, keeping the placement plate 5 in a vertical direction. During its rotation, the placement plate 5 is always concentric with the pipe casting cavity at a certain angle. At this time, the steel frame fixing cylinder 1 can be fixed by the clamping rod 25 and sent into the pipe casting cavity.

[0033] A coating mechanism is further provided on the side of the base, which is arranged near the end cover. The coating mechanism includes a steel frame 35 on the side of the base, on which an entry rod 36 is slidably connected, and an adjustment plate 37 is slidably connected to the entry rod 36 near the end cover end, and a coating block 38 is fixed to the end of the adjustment plate 37 away from the entry rod 36. The coating block 38 is hollow inside, and a feed pipe 39 is connected to the side of the coating block 38. A plurality of discharge holes 40 are provided on the top of the coating block 38. A sleeve 41 fixed to the steel frame 35 is provided on the outside of the entry rod 36, and a spiral groove 42 is provided on the side of the sleeve 41. A connecting block 43 is slidably provided inside the spiral groove 42, and one end of the connecting block 43 is fixed to the side of the entry rod 36. The entry rod 36 is rotatably connected to the end away from the end cover with a piston rod 44, and the other end of the piston rod 44 is connected to a fourth cylinder 45.

[0034] The bottom of the adjustment plate 37 is connected to a fifth cylinder 47 , a support rod 48 is fixed to the bottom of the fifth cylinder 47 , and the end of the support rod 48 away from the fifth cylinder 47 is fixed to the side of the entry rod 36 .

[0035] The coating block 38 is connected to a feeding pipe 39 on its side. In the present embodiment, a functional film, such as an antistatic film in a molten state, is introduced into the coating block 38. During coating, the fourth cylinder 45 is turned on. As the fourth cylinder 45 is driven, the entry rod 36 moves toward the end cover and gradually enters the interior of the pipeline. The feeding pipe 39 continuously feeds the material. At the same time, as the entry rod 36 moves forward, the connecting block 43 thereon moves along the spiral groove 42 of the sleeve 41, and then the entry rod 36 starts to rotate, driving the adjustment plate 37, the fifth cylinder 47 and the coating block 38 to rotate, and the feeding pipe 39 starts to wrap around the outside of the entry rod 36. Therefore, the coating block 38 starts to spirally advance, and gradually coats different areas of the inner wall of the pipeline. The thickness of the coating is the distance between the coating block 38 and the inner wall of the pipeline. At the same time, the distance can be adjusted by the fifth cylinder 47. The fifth cylinder 47 can drive the adjustment plate 37 to move, and then the adjustment plate 37 moves in the vertical direction relative to the entry rod 36, thereby adjusting the height of the coating block 38.

[0036] Based on the above-mentioned prefabrication molding mechanism, the quality control method for prefabrication molding of steel skeleton reinforced nylon pipes in this embodiment has a specific principle of quality control by changing the exposed thickness of the steel pipe frame net. Since the internal fluid scours the inner wall of the pipe during use, and at the same time, the steel skeleton net is prevented from being covered too deeply, which may cause the inner wall of the pipe to crack easily, the present invention controls the quality by adjusting the exposed thickness of the steel pipe frame net, further improves the overall quality of the pipe by coating, and can control the film thickness of the coating film, thereby controlling the quality of the coating film, and specifically includes the following steps: ①, wrapping the prepared steel skeleton net on the outside of the steel skeleton fixing tube 1; ②, extend the clamping rod 25 into the steel frame fixing tube 1 placed on the placement plate 5, turn on the servo motor 22, drive the screw 21 to rotate, and then drive the fixing plate 23 to move and send the fixed steel frame fixing tube 1 into the pipeline casting cavity; ③. After the steel skeleton fixing cylinder 1 enters, the second cylinder 12 is opened to drive the moving rod 11 to move toward the inside of the pipeline casting cavity, and the steel skeleton net is fixed by adsorption through the magnet 15; ④. After the steel skeleton net is fixed, the servo motor 22 is driven to reverse again, and the steel skeleton fixing cylinder 1 is taken out; ⑤. Open the third cylinder 28, which drives the clamping plate to move toward the axis of the steel frame fixing tube 1, and releases the conflict between the clamping block 26 and the inner wall of the steel frame fixing tube 1. At the same time, as the servo motor 22 continues to drive, the fixing plate 23 and the clamping rod 25 continue to move to the end of the fixing plate 2. At this time, the driving motor 34 is turned on to drive the cross bar 30 to rotate and drive different placement plates 5 to pass through the position of the clamping rod 25. At this time, the third cylinder 28 is continued to be opened to drive the clamping rod 25 to move. The scale bar 29 is used as a reference, and the distance between the clamping rods 25 can be adjusted to fix the inner diameter of the steel frame fixing tube 1. After selecting the target steel frame fixing tube 1 that matches the above-mentioned adjusted clamping rod 25, the servo motor 22 is driven to extend the clamping rod 25 into the steel frame fixing tube 1, and the clamping block 26 is fixed by friction with the inner wall of the steel frame fixing tube 1 to replace the steel frame fixing tube 1 with different inner diameters. ⑥. After the steel skeleton fixing cylinder 1 completely enters the interior of the pipe casting cavity, the rotating disk 24 blocks the end of the pipe casting cavity, and then connects the casting pipe 18, and casts toward the interior of the pipe casting cavity through the casting pipe 18; ⑦. After the bottom of the steel pipe frame mesh hits the poured nylon slurry, the second cylinder 12 is controlled again to drive the moving rod 11 to move toward the outside of the pipe pouring cavity, and the nylon slurry is filled between the steel frame fixing tube 1 and the pipe pouring cavity; ⑧, and then obtain the steel skeleton reinforced nylon pipe; ⑨.
