Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation pipe manufacturing, in particular to an integrated manufacturing and processing production line for thermal insulation pipes. Background Art

[0002] Insulated pipes are piping systems specially designed and manufactured to reduce heat loss during the transportation of the medium in the pipe, maintain the temperature of the medium, prevent condensation or frost on the pipe surface, ensure personnel safety, and improve system efficiency. Their main types include prefabricated direct-buried insulated pipes and on-site insulated pipes. They are mainly used in regional centralized heating, cooling, building HVAC, petrochemicals, electricity, food and beverages, pharmaceuticals, liquefied natural gas, refrigeration engineering, ships, etc.

[0003] The patent with application number CN202220824004.1 mentions "a thermal insulation pipe production line". This patent has a reasonable structure and simple operation, shortens the process docking time, and improves the production efficiency of the thermal insulation pipe.

[0004] However, the existing equipment cannot quickly and directly correct the position of the inner steel pipe after it is placed. At the same time, the position of the outer sheath is corrected when the insulation material is filled, resulting in eccentricity of the double-pipe combination during production, making the overall insulation uneven, which greatly affects the quality of the product. In addition, when the production of the outer sheath is synchronized with the filling of the insulation material, it is easy for the outer sheath to be incompletely cooled and the extrusion speed to be too fast, resulting in overall unevenness of the product, or incomplete filling of the internal filling material due to heating, further affecting the product quality.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. It is equipped with double-injection components. The switching motor and the switching operation frame are driven to move by the opening and closing hydraulic cylinder. The switching motor drives the switching operation frame to rotate. The lifting hydraulic cylinder drives the special-shaped integration frame and the fixed limit lifting frame to move up and down. The push-stick hydraulic cylinder drives the push-stick limit plate and the clamping electromagnet to push the inner wall of the steel pipe magnetically. The center position of the steel pipe is adjusted by multi-directional correction. The pressure treatment frame and the insertion matching plate are driven by the pressure electric push rod to move and fit to the side end of the steel pipe. The flip motor and the sealing electromagnet are used to combine the insertion integration plate and the insertion matching plate. The mating plate supports the inside of the outer sheath and centers the outer sheath through positioning and extrusion, so that the steel pipe and the outer sheath can be steadily fitted together, improving the speed and stability of the overall shaping. Through the three-stage coordination of rotation correction, lifting correction and magnetic support correction, and internal insertion and movement correction, the two groups of pipes can be steadily fitted together, reducing the occurrence of eccentricity between the pipes, ensuring the overall uniformity of subsequent insulation material filling, and improving product quality. In addition, through direct loading and synchronous correction, the correction waiting time is reduced and the processing efficiency is improved.

[0046] The extrusion molding process is carried out at both ends through the injection molding input box and the relay injection molding box. The pipe is shaped and measured by the vacuum molding machine, the molding limit column and the laser measuring instrument. The cooling fixed cavity and the exchange processing tube are used for heat exchange cooling and molding to realize the shape correction during extrusion molding. The relay feeding process is used to reduce the occurrence of unevenness on the outside and improve the quality of the outer sheath. At the same time, during extrusion molding, the material is extruded through both ends to ensure the feeding speed and the extrusion speed. The contact cooling is used to improve the molding speed and reduce the overall shape changes during extrusion due to insufficient cooling. The insulation material is filled between the steel pipe and the outer sheath through the injection processing pipe rack, the linkage solenoid valve and the foaming injection machine to realize synchronous filling of the material and the rapid cooling molding of the outer sheath to avoid the change of the filling material properties due to high temperature and ensure the product quality of the filling material. The pre-molding filling and the simultaneous filling on both sides of the pipe are coordinated with each other to ensure the filling speed while improving the compactness of the filling. At the same time, the synchronous coordination of multiple-stage processing is used to improve product quality while ensuring production efficiency.

[0047] Through multiple sections of different displacement support corrections, the position of the center of the steel pipe is changed, the internal extrusion expansion and fixed position centering are carried out to achieve accurate and uniform fitting of the two groups of pipes. Through the mutual cooperation of two-stage extrusion molding and internal cooling molding, and the use of discharge insulation filling and secondary insulation filling, the problem of eccentricity during assembly caused by the inability to correct the position of the steel pipe and the outer sheath in the existing technology is effectively solved. The overall uniformity of the product is effectively guaranteed, the thermal insulation effect of the product is guaranteed, and at the same time, the abnormal appearance and internal filling of the product due to the overall unevenness of the outer sheath or incomplete filling of the internal filling material are avoided. The accuracy of the overall alignment of the product and the compactness of the filling material can be effectively improved, and the production efficiency can be steadily improved while ensuring product quality.

[0048] 2. A pick-up and place guide support assembly is provided. The elastic laminating plate is pressed against the outer wall of the steel pipe by the pressure-limiting hydraulic cylinder. The elastic laminating plate is then pushed up and down along the inner limit matching sleeve by the pressure-limiting hydraulic cylinder to adjust the center alignment position. The traction processing block and the traction electromagnet are driven to move by the traction electric slide rail and the traction hydraulic cylinder. The traction electromagnet magnetically pulls the steel pipe, driving the steel pipe to correct the center position while simultaneously performing the loading process. This achieves the simultaneous processing of loading and center alignment correction, thereby improving the overall processing speed and product accuracy.

[0049] The load-bearing hydraulic cylinder drives the fixed fitting block, special-shaped bearing block and bearing electromagnet to magnetically position the steel pipe, and cooperates with the special-shaped bearing block to support and position the side end of the outer sheath pipe. The outward push electric slide rail drives the outward push operation frame, fixed fitting block and special-shaped bearing block to push the product out. The magnetic positioning traction at both ends and the middle segment support are used to avoid uneven force on the pipeline and tilting and falling due to single-position support, and reduce the force on the outer sheath pipe and insulation material, reduce pipeline deformation, ensure discharge stability and speed, and ensure product quality. Through the cooperation of feed correction and multi-position support discharge, two-step simultaneous operation is realized, reducing the waiting time for feeding and unloading, improving the speed and efficiency of processing, and ensuring product quality.

[0050] In summary, through the cooperation between the double-injection simultaneous components and the pick-up and placement support components, through the simultaneous processing of the steel pipe and outer sheath fitting, steel pipe loading, insulation material filling and compacting, and product support and discharge, multiple groups of operations can be coordinated simultaneously, reducing the waiting time during product production and improving the overall production efficiency.

A load-bearing traction block 411 is installed on the top of the multiple traction hydraulic cylinders 410. The longitudinal sections of the fixed fitting block 405, the special-shaped load-bearing block 407 and the load-bearing traction block 411 are arc-shaped, ensuring support for the side end of the pipeline and stable positioning and traction processing to prevent the pipeline from rotating and shaking and causing it to fall off. A traction electromagnet 412 is installed on the top of the load-bearing traction block 411;

[0095] An inner limit fitting sleeve 413 is installed at the top of the special-shaped integration frame 320. A plurality of pressure limiting hydraulic cylinders 414 are symmetrically connected to the side ends of the inner limit fitting sleeve 413. An elastic fitting plate 415 is installed at one end of the pressure limiting hydraulic cylinder 414.

[0096] A laser measuring instrument 416 is installed at one end of the fixed limit lifting frame 338, and a pushing hydraulic cylinder 417 is symmetrically installed at one end of the sliding directional frame 318;

[0097] One end of the two pushing hydraulic cylinders 417 is equipped with a pushing processing plate 418, and one end of the pushing processing plate 418 is equipped with an adsorption electromagnet 419. The pushing processing plate 418 and the adsorption electromagnet 419 are both placed on the side end of the fixed limit lifting frame 338 so that when the inner push processing and the inner push linkage are in progress, the processing and directional processing can be steadily coordinated;

[0098] In order to ensure the stable operation of the equipment, the input ends of the external push electric slide 402, the load-bearing hydraulic cylinder 404, the load-bearing electromagnet 406, the traction electric slide 408, the traction hydraulic cylinder 410, the traction electromagnet 412, the pressure-limiting hydraulic cylinder 414, the laser measuring instrument 416, the pushing hydraulic cylinder 417 and the adsorption electromagnet 419 are all electrically connected to the output end of the external controller.

[0099] The working principle and use process of the present invention are as follows: when producing the insulated pipe, the external extruder is connected to the injection molding input box 306 and the relay injection molding box 307 through the adapter, the exchange processing tube 305 is combined with the external cooling device, and the staff hoists the rust-cleaned steel pipe to the position of the special-shaped integration frame 320 through the external hoisting equipment, and inserts the steel pipe into the position of the inner limit matching sleeve 413. At this time, the pressure limiting hydraulic cylinder 414 in the inner limit matching sleeve 413 drives the elastic fitting plate 415 to move along the inner limit matching sleeve 413 toward the position of the steel pipe, and finally fits the side end of the elastic fitting plate 415 with the steel pipe. The pressure limiting hydraulic cylinder 414 drives the elastic fitting plate 415 to move and push the steel pipe to move up and down along the inner limit matching sleeve 413 to adjust the center of the circle alignment position;

[0100] At the same time, the traction processing block 409 is driven by the traction electric slide 408 to move along the special-shaped integration frame 320, and the traction hydraulic cylinder 410 drives the bearing traction block 411 to rise and fall, so that the top of the side end of the traction electromagnet 412 fits the bottom of the side end of the steel pipe, and the steel pipe and the bearing traction block 411 are magnetically attracted and combined by the traction electromagnet 412. After the combination and fixation are completed, the traction processing block 409, the traction hydraulic cylinder 410 and the bearing traction block 411 are driven by the traction electric slide 408 to move along the special-shaped integration frame 320, and the steel pipe is driven to move along the inner limit matching sleeve 413 and the elastic fitting plate 415 to insert the steel pipe into the outer end of the switching operation frame 323. At this time, the pushing and limiting plate 325 is driven by the pushing and limiting hydraulic cylinder 324 to move along the switching operation frame 323, so that the pushing and limiting plate 325 and the clamping electromagnet 326 fit the inner wall of the steel pipe to realize the insertion and loading process;

[0101] After the steel pipe is inserted and fitted, the steel pipe is magnetically fixed by the clamping electromagnet 326 to realize the steel pipe feeding process. The feeding center is adjusted and the push-and-stick limit plate 325 is used to support and correct the pipe according to the inner wall thickness and actual size of the pipe. This ensures that the steel pipe can be stably supported during feeding and continuous movement, avoiding the steel pipe from deviating and detaching, which would cause eccentricity during subsequent filling, and effectively improving the quality of the product.

[0102] After the loading process and connection and fixation, the opening and closing hydraulic cylinder 321 drives the switching motor 322, the switching operation frame 323, the fixed limit lifting frame 338 and the fixed rotation correction frame 2 to move along the sliding directional frame 318 and the special-shaped integration frame 320, and cooperates with the lifting hydraulic cylinder 319 to drive the sliding directional frame 318 and the special-shaped integration frame 320 to rise and fall separately, and the lifting hydraulic cylinder 319 drives the fixed limit lifting frame 338 and the fixed rotation correction frame 2 to rise and fall separately, so that the switching operation frame 323 and the steel pipe are separated from the inner limit matching sleeve 413. At this time, the switching motor 322 drives the switching operating frame 323 to rotate along the fixed limit lifting frame 338, rotating the steel pipe to the position of the group limit integration frame 1, and the opening and closing hydraulic cylinder 321 drives the switching motor 322, the switching operating frame 323, the fixed limit lifting frame 338 and the fixed rotation correction frame 2 to move and reset, so that the side end of the switching operating frame 323 is fitted with the side end of the fixed limit column 302, thereby completing the steel pipe feeding process, and the insertion limit frame 328 is driven by the plug-in electric slide rail 327 to move and fit onto the side end of the steel pipe;

[0103] During the process of feeding and loading the steel pipe to the production position, the extruder performs hot melt extrusion on the plastic masterbatch of the outer sheath, and the extruded plastic enters the inner side of the vacuum setting machine 301 along the extruder and the injection molding input box 306, and is extruded and shaped by the vacuum setting machine 301 and the shaping limit column 302. The extruded plastic is continuously injected and moved, and gradually moves toward the position of the laser measuring instrument 303. At this time, the cooling liquid is injected into the cooling fixed cavity 304 through the external cooling device and the exchange processing tube 305. The coolant absorbs heat through the shaping limit column 302 to cool the extruded plastic, thereby extruding the extruded plastic to produce an outer sheath pipe. When the outer sheath pipe moves through the laser measuring instrument 303, the inner and outer diameters are measured by the laser measuring instrument 303. When a depression occurs, the extruded plastic enters the vacuum setting machine 301 along the relay injection molding box 307, fills the depressed position, and is cooled and formed again. The formed outer sheath pipe moves along the shaping limit column 302 and is discharged;

[0104] When the outer sheath is discharged, the pressure treatment frame 330 and the insertion matching plate 331 are driven to move by the pressure electric push rod 329 located at the insertion limit frame 328. At this time, the flip motor 332 drives the insertion integration plate 333 to rotate along the insertion matching plate 331, so that the insertion integration plate 333 fits the side end of the insertion matching plate 331. At this time, the sealing electromagnet 334 is used to magnetically fix the insertion matching plate 331 and the insertion integration plate 333, and the outer sheath tube moves along the fixed limit column 30 2 and the cut inner empty frame 313 are moved to the insertion matching plate 331 and the insertion integration plate 333. At this time, the insertion matching plate 331 and the insertion integration plate 333 are used to perform shaping and positioning. When the outer sheath pipe moves to the position of the insertion limiting frame 328, the injection processing pipe rack 335 is opened by the linkage electromagnetic valve 336, and the foaming injection machine 337 is used to inject foam insulation foam between the steel pipe and the outer sheath pipe. The foam insulation foam foams quickly and supports and positions the steel pipe and the outer sheath pipe.

[0105] During the injection process, the piezoelectric push rod 329 drives the piezoelectric processing frame 330, the insertion matching plate 331 and the insertion integration plate 333 to move, gradually changing the position of the foaming injection. At the same time, the cutting electric slide 312 drives the cutting inner empty frame 313 to move along the group limit integration frame 1, changing the cutting position of the cutting inner empty frame 313, and the pasting electric slide 310 drives the pasting double convex frame 311 to move along the transposition pasting plate 309. The inner wall of the outer sheath tube is supported and protected by the pasting double convex frame 311, and the cutting hydraulic cylinder 316 drives the cold cutting insertion knife 317 to move and insert into the outer sheath The inner side of the tube is fitted with the side end of the double convex frame 311. At this time, the circumferential electric slide 308 drives the transposition laminating plate 309 and the double convex frame 311 to rotate along the fixed limit column 302, and the circular electric slide 314 drives the cutting processing frame 315 to rotate along the inner empty frame 313 of the cut, thereby driving the cold cutting insertion knife 317 to continuously extrude and cut the outer sheath tube. During the cutting process, the double convex frame 311 is used to protect the pipe at the incision position, so as to avoid the pipe from being greatly deformed due to cutting, which affects the subsequent production, thereby improving the stability of product production and product quality.

[0106] At this time, the flip motor 332 drives the insertion integration plate 333 to reset, the plug-in electric slide rail 327 drives the insertion limit frame 328 to reset, the opening and closing hydraulic cylinder 321 and the switching motor 322 drive the switching operation frame 323 to rotate along the fixed limit lifting frame 338, and the semi-finished product is rotated to the position of the fixed rotation correction frame 2. At this time, the pushing hydraulic cylinder 417 drives the pushing processing plate 418 and the adsorption electromagnet 419 to fit the side end of the steel pipe, pushing the steel pipe to move along the switching operation frame 323 to achieve alignment and fitting processing, and the flip motor 332 drives the insertion integration plate 333 to rotate. Insert the insert matching plate 331 and the insert integration plate 333 located at the position of the fixed rotation correction frame 2 into between the steel pipe and the outer sheath pipe. At this time, the piezoelectric push rod 329 drives the pressure treatment frame 330 to move, and the injection treatment pipe frame 335 is placed to the position where the foam filling is not done. The foam insulation agent is injected into the interior again. Through the primary injection support and the secondary injection supplementary sealing, the stable production and processing of the insulation pipe is achieved. In addition, the center of the two groups of pipes is centered by the embedded sliding feeding to avoid large eccentricity of the product, improve the quality of the product and ensure its production efficiency.

[0107] After the product production is completed, the switching operation frame 323 and the product are rotated and moved to the unloading position by the opening and closing hydraulic cylinder 321 and the switching motor 322 again, and the fixed fitting block 405 and the special-shaped bearing block 407 are driven to rise by the load-bearing hydraulic cylinder 404, and the steel pipe and the fixed fitting block 405 are magnetically combined by the load-bearing electromagnet 406, and the side end of the outer sheath pipe is supported and positioned in cooperation with the special-shaped bearing block 407, and the outward electric slide rail 402 drives the outward pushing operation frame 403, the load-bearing hydraulic cylinder 404, the fixed fitting block 405 and the special-shaped bearing block 407 to move along the smooth outer row plate 401, thereby taking the product out from the side end of the switching operation frame 323. After taking it out, the product is hoisted by external hoisting equipment to realize the unloading processing, and the magnetic positioning traction at both ends and the middle segment support processing are used to avoid the uneven force on the pipeline caused by single-position support, and reduce the force on the outer sheath pipe and the insulation material, reduce pipeline deformation, ensure the stability and speed of unloading, and ensure the quality of the product.
