Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of composite pipe edge sealing, and particularly relates to an extrusion molding device for an integrated pipe fitting for sealing the end of a composite pipe. Background Technique
[0002] A composite pipe is a pipe composed of two or more different materials. This combined design aims to enhance the reliability, durability, and applicability of the pipe. Common composite pipes include glass fiber tape (wire) reinforced composite pipes, steel-plastic composite pipes, aluminum-plastic composite pipes, plastic-coated composite pipes, etc. These pipes combine the advantages of different materials to meet the usage requirements under various complex working conditions. The manufacturing processes of composite pipes are diverse, including the drawing method, explosive cladding method, hydroforming method, extrusion method, etc. Different manufacturing processes are applicable to different pipe materials and specification requirements.
[0003] In the patent with the application number 202311801639.5, a composite pipe and an edge sealing method are disclosed. If the composite pipe described in this application leaks water, the isolation layer can limit the water leakage area to both ends of the pipe body, thus preventing water leakage or bulge from penetrating the entire outer pipe and the reinforcement pipe, and further affecting the connection strength between the outer pipe, the inner pipe, and the reinforcement pipe, and ultimately reducing the structural strength of the composite pipe. Combining the above application and comparing with the existing composite pipe edge sealing methods, after the existing composite pipes are extruded and processed, since the pipes are composed of multiple layers, leakage and other problems are likely to occur at the ends of the pipes, which will affect the sealing performance of the pipes and also their stability. For this reason, we propose an extrusion molding device for an integrated pipe fitting for sealing the end of a composite pipe. Content of the Utility Model
[0004] The purpose of the utility model is to provide an extrusion molding device for an integrated pipe fitting for sealing the end of a composite pipe, so as to solve the problem that, compared with the existing composite pipe edge sealing methods, after the existing composite pipes are extruded and processed, since the pipes are composed of multiple layers, leakage and other problems are likely to occur at the ends of the pipes, which will affect the sealing performance of the pipes and also their stability as mentioned in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1
[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the present utility model provides a technical solution: The composite pipe edge sealing device is mainly used for the end sealing or edge sealing treatment of composite pipes. Through specific processes and technologies, this device ensures that the sealed or edge-sealed part of the composite pipe is firm and beautiful, and avoids problems such as loose sealing caused by impurities adhering to the pipe wall. A device for extrusion molding of an integrated pipe fitting for edge sealing at the end of a composite pipe includes an edge sealing extrusion main machine 100. A pipe inlet frame 101 is fixedly installed at the bottom on one side of the edge sealing extrusion main machine 100. Rollers are arranged on the pipe inlet frame 101 and are used to import the pipes to be processed. A pipe positioning inlet rod 102 is installed on one side inside the edge sealing extrusion main machine 100. An extrusion seat 103 is installed at the top on the other side of the edge sealing extrusion main machine 100. Through the rollers installed on the pipe inlet frame 101, when the stitching pipe is fed by the pipe feeding mechanism, the stability of the pipe can be ensured, so as to better use for edge sealing.
[0024] Specifically, an extrusion hole 201 is formed inside the extrusion seat 103, and the extrusion hole 201 extends to the inside of the edge sealing extrusion main machine 100. An electric push cylinder 200 is installed on the other side of the edge sealing extrusion main machine 100. One end of the electric push cylinder 200 is located inside the edge sealing extrusion main machine 100 and is equipped with a push plate 206. A pipe body push rod 207 is installed at the edge of the push plate 206. An annular ring expansion and contraction groove 208 is formed at the edge of the pipe positioning and guiding rod 102 inside the edge sealing extrusion main machine 100. An extrusion annular ring 205 is installed inside the annular ring expansion and contraction groove 208. A baffle lifting seat 300 is fixedly installed at the outer surface edge of the extrusion annular ring 205. An arc-shaped baffle 301 is installed at the end of the extrusion annular ring 205 on one side of the baffle lifting seat 300. A push block 204 is installed on the outer surface of the extrusion annular ring 205. A limiting groove 209 is formed at the inner edge of the edge sealing extrusion main machine 100. An electric push cylinder 202 is installed at one end of the limiting groove 209 inside the edge sealing extrusion main machine 100. One end of the electric push cylinder 202 is provided with a telescopic push rod 203, and the other end of the telescopic push rod 203 is arranged on the push block 204. When using the edge sealing device in this application to perform edge sealing processing on the composite pipe, the pipe is sent into the edge sealing extrusion main machine 100 through the pipe feeding mechanism, and is supported and guided by the pipe guiding frame 101 during the pipe feeding process, so as to ensure the stability when the pipe enters. And the pipe positioning and guiding rod 102 arranged on the edge sealing extrusion main machine 100 is inserted into the inside of the pipe for positioning. When the pipe is completely inserted, the electric push cylinder 200 works to push the push plate 206 to move, and the pipe body push rod 207 at one end of the push plate 206 pushes the composite pipe out a certain distance. Then the electric push cylinder 200 drives the push plate 206 and the pipe body push rod 207 to reset, so that a certain gap is reserved at the end of the pipe, which can be better wrapped around the end of the pipe during edge sealing extrusion. Then the baffle lifting cylinder 302 on the baffle lifting seat 300 works, and the baffle lifting cylinder 302 drives the baffle lifting screw rod 304 inside the baffle lifting seat 300 to rotate. When the baffle lifting screw rod 304 rotates, it drives the baffle lifting block 303 to move through the thread. At the same time, the baffle lifting block 303 will drive the arc-shaped baffle 301 to squeeze towards one end of the composite pipe. Then the molten edge sealing material is fed into the extrusion seat 103, and the molten edge sealing material enters the cavity formed by the arc-shaped baffle 301 and the extrusion annular ring 205 through the extrusion hole 201. After the edge sealing material is formed, the arc-shaped baffle 301 resets, and then the composite pipe can be taken out. The formed edge sealing material is wrapped around the end of the composite pipe, thus ensuring the structural stability of the composite pipe.
[0025] Embodiment 2
[0026] Please refer to Figure 1 and Figure 2, the present utility model provides a technical solution: an extrusion molding device for an end-edge sealing integrated pipe fitting of a composite pipe. The extrusion ring 205 is pushed by the electric push cylinder two 202 to move the telescopic push rod 203 and the push block 204, and when the extrusion ring 205 moves, it is limited to move in the ring telescopic groove 208. While ensuring the stable movement of the extrusion ring 205, the stability of this structure is improved. A retaining edge lifting cylinder 302 is fixedly installed on the top of the retaining edge lifting seat 300. One end of the retaining edge lifting cylinder 302 is installed with a retaining edge lifting screw rod 304 inside the retaining edge lifting seat 300. An integrated retaining edge lifting block 303 is provided on the arc-shaped retaining edge 301. During the edge sealing process, if the processing requirements or types of the pipes are different and the edge sealing distance needs to be adjusted, before the arc-shaped retaining edge 301 is closed, the electric push cylinder two 202 can work to push the telescopic push rod 203 and the push block 204 to move telescopically. When the push block 204 moves, it drives the extrusion ring 205 to stretch a certain distance in the ring telescopic groove 208, thereby changing the width of the edge sealing, enabling the device to complete different edge sealing requirements, and thus improving the practicability and functionality of the device.
[0027] Specifically, the retaining edge lifting screw rod 304 passes through the retaining edge lifting block 303 by threads, and the arc-shaped retaining edge 301 is driven to lift by the arc-shaped retaining edge 301 and the retaining edge lifting screw rod 304. While ensuring the structural stability of the arc-shaped retaining edge 301, the arc-shaped retaining edge 301 is of a fan-shaped structure, and four arc-shaped retaining edges 301 are arranged in an array on the extrusion ring 205. At the same time, the displacements of all four arc-shaped retaining edges 301 can be adjusted. After the edge sealing is formed, the arc-shaped retaining edge 301 can be moved and opened to facilitate the removal of the pipe after the edge sealing is completed, thereby improving the practicability of this structure.
[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
