Technical Field

[0001] The utility model mainly relates to the technical field of manufacturing and processing of steel wire mesh skeleton composite pipes, and in particular to a steel wire mesh skeleton composite pipe flanging device. Background Art

[0002] The steel wire mesh skeleton composite pipe is a new type of pipeline. It uses high-strength plasticized steel wire mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. The high-density polyethylene is used as the matrix. The high-performance high-density polyethylene modified adhesive resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene. Since the steel wire mesh skeleton composite pipe uses high-quality materials and advanced production technology, it has better pressure resistance and flexibility, so it is often used in long-distance buried water supply, gas pipeline systems and other fields.

[0003] In order to better realize the connection and other tasks of the wire mesh skeleton composite pipe, it is usually necessary to use a flanging device to expand and flanging the wire mesh skeleton composite pipe. During processing, the wire mesh skeleton composite pipe is limited and fixed, and then the flanging die is driven by the telescopic cylinder to approach the pipe mouth of the wire mesh skeleton composite pipe that needs to be flanging, and the flanging process is performed. However, the existing flanging device generally has a flanging die of a specific size fixedly installed on the telescopic end of the telescopic cylinder, and is usually only suitable for a wire mesh skeleton composite pipe with a specific aperture. If the wire mesh skeleton composite pipe with different apertures is flanging, it cannot be effectively applied. Its use is relatively limited and inconvenient to use. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0027] See attached Figure 1-4 A flanging device for a steel mesh skeleton composite pipe of the present embodiment comprises a flanging bottom die 1 and a plurality of plug-in sleeves 2, and the outer diameters of different plug-in sleeves 2 are respectively adapted to the apertures of different steel mesh skeleton composite pipes. The flanging bottom die 1 comprises a flanging baffle 101, and a sleeve shaft 102 is correspondingly provided in the middle of one side of the flanging baffle 101, and a threaded shaft 105 is correspondingly provided in the middle of one side of the sleeve shaft 102, and a fastening nut 3 is correspondingly threadedly installed on the threaded shaft 105. An inner hole 201 is correspondingly provided in the middle of the plug-in sleeve 2, and one side of the inner hole 201 is penetrated, and a through hole 203 for the threaded shaft 105 to pass through is correspondingly provided in the middle of the other side of the inner hole 201, and a rounded corner 202 is formed by extending outward from the edges of one side of the plug-in sleeve 2 away from the through hole 203, and the plug-in sleeve 2 is slidably plugged into the sleeve shaft 102 and is tightened and fixed by the fastening nut 3.

[0028] Specifically, the diameter of the inner hole 201 of the plug sleeve 2 is matched with the outer diameter of the sleeve shaft 102. An annular protrusion 204 is formed around the outer side of the inner hole 201 of the plug sleeve 2, and an annular groove 103 matching the annular protrusion 204 is correspondingly provided around the sleeve shaft 102 on the flange baffle 101. The annular protrusion 204 is correspondingly inserted into the annular groove 103. Through the installation and matching of the annular protrusion 204 and the annular groove 103, the coaxiality of the plug sleeve 2 and the sleeve shaft 102 is further guaranteed, making the installation and use of the plug sleeve 2 more stable and reliable.

[0029] A mounting shaft 104 is correspondingly provided in the middle of the other side of the flanged baffle 101, and the mounting shaft 104 is correspondingly connected to the telescopic end of the telescopic cylinder. The axes of the mounting shaft 104, the flanged baffle 101, the sleeve shaft 102, and the threaded shaft 105 are all located on the same straight line, and the axes of the sleeve shaft 102 and the plug-in sleeve 2 installed thereon are also located on the same straight line. When the annular protrusion 204 is fully inserted into the annular groove 103, the fillet 202 on the plug-in sleeve 2 fits with the flanged end face 106 on one side of the flanged baffle 101. When flanging, according to the aperture size of the steel wire mesh skeleton composite pipe to be flanging, a plug sleeve 2 of a suitable size is selectively installed on the sleeve shaft 102 of the flanging bottom mold 1, so that the plug sleeve 2 is adapted to the aperture size of the steel wire mesh skeleton composite pipe to be flanging, and then the telescopic cylinder is used to drive the flanging bottom mold 1 and the plug sleeve 2 to approach the pipe mouth to be flanging, so that the sleeve shaft 102 and the plug sleeve 2 thereon extend into the pipe mouth to be flanging respectively, when the inner wall of the pipe mouth of the steel wire mesh skeleton composite pipe contacts the fillet 202, the pipe mouth of the steel wire mesh skeleton composite pipe is first opened by the fillet 202, and as the flanging bottom mold 1 and the plug sleeve 2 continue to move, the pipe mouth of the steel wire mesh skeleton composite pipe will contact the flanging end face 106 on one side of the flanging baffle 101, and then the pipe mouth is flanging by using the flanging end face 106, thereby being able to better ensure the flanging effect of the pipe mouth.

[0030] The fastening nut 3 adopts a butterfly nut, which is convenient for twisting. The maximum diameter of the area involved in the fastening nut 3 is smaller than the outer diameter of all the plug-in sleeves 2, so that the plug-in sleeves 2 can be smoothly inserted into the pipe mouth of the wire mesh skeleton composite pipe. It is worth noting that although the flanging device described in this embodiment is a device for flanging the wire mesh skeleton composite pipe, it is because the device is a further improvement of the existing flanging device made by the applicant during the flanging process of the wire mesh skeleton composite pipe. At present, it is beneficial to the flanging process of the wire mesh skeleton composite pipe. However, those skilled in the art have reason to use the technical solution of this application in the flanging process of similar other pipe fittings, and its actual scope of use is not limited by the name.
