Description

Technical Field

[0001] The utility model relates to the technical field of FRP pipes, in particular to an FRP pipe rubber-wrapped tooling. Background Art

[0002] FRP, also known as fiberglass or fiberglass reinforced plastic, is a composite material made of polymer epoxy resin as the matrix and fiberglass or carbon fiber as the reinforcement through a composite process. Its advantages include lightness, corrosion resistance, aging resistance, and insulation. Therefore, it is used to manufacture various sports equipment, pipelines, shipbuilding, automobile and electronic product housings and printed circuit boards.

[0003] During multiple uses, the FRP pipe needs to be continuously polished. Over time, the pipe wall will become thin, and the compressive strength cannot meet customer needs. The pipe wall needs to be rewrapped and coated with glue. In the prior art, the installation and fixation of the FRP pipe coating is too tight, and it is difficult to fall off after the subsequent coating is completed. In addition, the fixation is too tight, resulting in the edge of the FRP pipe not being able to be normally rewound during the rewrapping and coating treatment, and a second edge rewrapping treatment is required.

[0004] Therefore, it is necessary to provide a FRP pipe rubber-wrapped tooling to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide an FRP tube rubber coating tooling to solve the problem in the above-mentioned background technology that the FRP tube is fixed too tightly, resulting in the edge of the FRP tube cannot be normally rewound when it is rewound for rubber coating, and a second edge rewound treatment is required subsequently. The technical solution of the utility model is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an FRP tube rubber-wrapped tooling, comprising a hollow shaft, core shafts are installed at both ends of the inner side of the hollow shaft, one end of the core shaft is connected to a plug, a bearing sleeve is installed on the outer wall of the plug, end covers are installed at both ends of the outer wall of the hollow shaft, and a pipe is installed on the end opposite to the end cover.

[0007] Preferably, the hollow shaft is a DN80 pipe.

[0008] Preferably, the bearing sleeve adopts 6210 bearing.

[0009] Preferably, the opposite end of the end cover is in a conical structure, and the opposite end of the conical structure is in a parallel structure.

[0010] Preferably, top covers are provided at both ends of the outer wall of the hollow shaft, and the protruding structure of the top cover is provided with threaded holes.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Since the end cover of the utility model adopts a conical structure, the edge of the pipe wall can be fully coated with glue, so that the appearance of the pipe after the coating is the same as that of a new pipe, thereby saving the cost of new production and reducing the procurement cost. In addition, the set conical structure also facilitates demoulding after the rewinding is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0019] See also Figure 1-3 A FRP tube rubber-wrapped tooling comprises a hollow shaft 1, a core shaft 2 is installed at both ends of the inner side of the hollow shaft 1, a plug 3 is connected to one end of the core shaft 2, a bearing sleeve 4 is installed on the outer wall of the plug 3, end covers 5 are installed at both ends of the outer wall of the hollow shaft 1, and a pipe 6 is installed at the opposite end of the end cover 5.

[0020] like Figure 1-3 As shown, the hollow shaft 1 adopts a DN80 pipe, which has good compression resistance.

[0021] like Figure 1-3 As shown, the bearing sleeve 4 adopts a 6210 bearing, which has good radial and axial loads.

[0022] like Figure 1-3 As shown, the opposite end of the end cover 5 is a conical structure, and the opposite end of the conical structure is a parallel structure. The end cover adopts a conical structure, which can fully coat the edge of the pipe wall with rubber, so that the appearance of the pipe 6 after the rubber coating treatment is the same as that of a new pipe, thereby saving the new manufacturing cost and reducing the procurement cost.

[0023] like Figure 1-3 As shown, top covers 7 are also provided at both ends of the outer wall of the hollow shaft 1, and the protruding structure of the top cover 7 is provided with threaded holes. The threaded holes can be used to press the hollow shaft 1 and the core shaft 2 into close contact with the top cover 7 to avoid shaking of the hollow shaft during the subsequent rewinding process.

[0024] Working principle: When in use, first install the pipe 6 to the outside of the hollow shaft 1, support the inner wall of the pipe 6 through the parallel structure set by the end cover 5, and then press the two ends of the pipe 6 through the set conical structure, and then install the tooling on the winding machine through the set bearing sleeve 4 to rotate and perform re-winding. The winding machine is a prior art and will not be described in detail here. Since the end cover 5 adopts a conical structure, the edge of the pipe wall can be fully coated with glue, so that the appearance of the pipe 6 after the coating is the same as that of a new pipe, thereby saving the cost of new production and reducing the procurement cost. In addition, the set conical structure also facilitates demolding after the re-winding is completed.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
