Description

Technical Field

[0001] This utility model relates to the field of internal forming positive mesh device structure, specifically a split steel skeleton plastic composite tube internal forming positive mesh device. Background Technology

[0002] Currently, most steel-framed straight pipe production lines use outdated first-generation internal forming mold structures, where the main mesh structure and the retaining ring are integrated. In this structure, the steel mesh positioning ring and the retaining ring are connected by evenly distributed connecting ribs. To ensure the connection dimensions of the composite pipe between the steel mesh positioning ring and the retaining ring, the main mesh positioning ring cannot be too thick, and its thickness is subject to certain limitations.

[0003] In production practice, with the increasing demands for product quality, PE raw materials are now primarily made from PE100 grade materials, and the strength and diameter of the steel wire are continuously being increased. Because PE100 grade raw materials have high molding pressure, the connecting ribs are prone to causing pipe molding quality problems. Furthermore, due to the thinness of the positioning rings in the mesh structure, they are easily deformed by the steel mesh, thus affecting product quality and production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a split-type steel-framed plastic composite pipe internal forming positive mesh device. This split-type steel-framed plastic composite pipe internal forming positive mesh device sets the positive mesh structure and the baffle ring as separate structures, eliminates the integrally connected connecting ribs, and increases the thickness of the positioning ring of the positive mesh structure, thereby solving the pipe forming quality problems and positioning ring deformation problems that are prone to occur in the existing integrated positive mesh structure.

[0005] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a split-type steel-framed plastic composite pipe internal forming positive mesh device, including a baffle ring; A receiving sleeve, which is coaxially disposed on one side of the retaining ring; A positive mesh structure is coaxially disposed on the side of the receiving sleeve away from the material retaining ring; A connecting sleeve is coaxially disposed on the side of the positive mesh structure away from the receiving sleeve.

[0006] In some embodiments, the baffle ring includes a ring body; A connecting protrusion ring is coaxially disposed on the side of the ring body away from the receiving sleeve; The first positioning ring groove is coaxially disposed on the side of the ring body away from the connecting protrusion.

[0009] In some embodiments, the diameter of the frustum ring near the first positioning ring is greater than the diameter of the frustum ring near the connecting ring.

[0010] In some embodiments, the positive mesh structure includes a positive mesh body, which is coaxially disposed on the side of the receiving sleeve away from the retaining ring; The second positioning ring is coaxially disposed on the side of the positive mesh body near the receiving sleeve and is inserted into the groove of the second positioning ring. The third positioning ring groove is coaxially located on the side of the main body away from the receiving sleeve, and the connecting sleeve is inserted into the third positioning ring groove.

[0011] In some embodiments, the connecting sleeve is a conical sleeve, and the diameter of the connecting sleeve on the side away from the main mesh structure is larger than the diameter of the connecting sleeve on the side closer to the main mesh structure.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-2 A split-type steel-framed plastic composite pipe internal forming positive mesh device includes a baffle ring 1, a receiving sleeve 2, a positive mesh structure 3, and a connecting sleeve 4. All components are coaxially arranged and connected sequentially. The baffle ring 1 can be connected and fixed to external equipment to position the internally formed positive mesh structure and block raw materials flowing to it. The receiving sleeve 2 is coaxially located on one side of the baffle ring 1, guiding the molten plastic to flow smoothly and transition, reducing flow resistance and pressure loss. The positive mesh structure 3 is coaxially located on the side of the receiving sleeve 2 away from the baffle ring 1, forming and positioning the steel frame and molten plastic. The connecting sleeve 4 is coaxially located on the side of the positive mesh structure 3 away from the receiving sleeve 2, connecting to external equipment and cooperating with the baffle ring 1 to position and fix the internally formed positive mesh structure.

[0019] In some embodiments, the retaining ring 1 includes a ring body 11, a connecting protrusion ring 12, and a first positioning ring groove 13. The connecting protrusion ring 12 is coaxially disposed on the side of the ring body 11 away from the receiving sleeve 2, which facilitates connection and fixation with external equipment. Its cross-section can be L-shaped, and through the split ring, it simultaneously locks the coaxial fixing sleeve and the connecting protrusion ring 12 to achieve a fixed connection between the retaining ring 1 and the external equipment, thereby improving the installation stability of the overall structure. The first positioning ring groove 13 is coaxially disposed on the side of the ring body 11 away from the connecting protrusion ring 12, and can be inserted and cooperated with the first positioning ring 21 to achieve accurate positioning and stable connection between the retaining ring 1 and the receiving sleeve 2.

[0020] In some embodiments, the receiving sleeve 2 includes a first positioning ring 21, a frustum-shaped ring 22, a connecting ring 23, and a second positioning ring groove 24. The first positioning ring 21 is inserted into the first positioning ring groove 13 of the retaining ring 1, thereby achieving precise positioning and stable connection between the retaining ring 1 and the receiving sleeve 2. The frustum-shaped ring 22 is coaxially disposed on one side of the first positioning ring 21, which can guide the flow of molten plastic and facilitate its flow. The connecting ring 23 is coaxially disposed on one side of the frustum-shaped ring 22, which can realize the connection transition. The second positioning ring groove 24 is disposed on one side of the connecting ring 23 and can be inserted into the second positioning ring 22 to ensure the coaxiality and connection stability between the receiving sleeve 2 and the positive mesh structure 3.

[0021] In some embodiments, the diameter of the frustum ring 22 near the first positioning ring 21 is larger than the diameter of the frustum ring 22 near the connecting ring 23. The gradual diameter can make the molten plastic flow more smoothly, reduce flow resistance and pressure loss, and avoid pressure sudden changes that may affect the plastic molding effect.

[0022] In some embodiments, the mesh structure 3 includes a mesh body 31, a second positioning ring 32, and a third positioning ring groove 33. The mesh body 31 is coaxially disposed on the side of the receiving sleeve 2 away from the retaining ring 1, which can shape and position the steel skeleton and molten plastic. This is prior art and will not be described in detail here. Due to the split design, the thickness of the positioning ring of the mesh body 31 can be appropriately increased, which improves its structural strength and makes it less susceptible to deformation by the steel mesh. The second positioning ring 32 is disposed on one side of the mesh body 31 and is inserted into the second positioning ring groove 24 of the receiving sleeve 2, which can realize the precise positioning and stable connection between the receiving sleeve 2 and the mesh structure 3. The third positioning ring groove 33 is coaxially disposed on the side of the mesh body 31 away from the receiving sleeve 2, and a connecting sleeve 4 is inserted into the third positioning ring groove 33, which can realize the positioning connection between the mesh structure 3 and the connecting sleeve 4.

[0023] In some embodiments, the connecting sleeve 4 may be a conical sleeve, and the diameter of the connecting sleeve 4 on the side away from the positive mesh structure 3 is larger than the diameter of the connecting sleeve 4 on the side close to the positive mesh structure 3, which can guide the molten plastic to be placed between the connecting sleeve 4 and the conical ring 22, which facilitates the forming of the steel skeleton plastic composite pipe.

[0024] In some embodiments, a pad 5 is also included. The pad 5 is coaxially disposed on the side of the connecting sleeve 4 away from the main mesh structure 3, serving as a buffer and protection, reducing direct collisions and wear between the connecting sleeve 4 and subsequent equipment, and extending the service life of the equipment. An isolation annular groove may be provided on the side of the connecting sleeve 4 away from the main mesh structure 3. The isolation annular groove can increase the contact area between the pad 5 and the connecting sleeve 4, thereby reducing the pressure exerted by the pad 5 on the connecting sleeve 4.

[0025] The specific working principle is as follows: The components are interlocked to form the overall structure of the internal forming positive mesh device, which is then fitted onto the external device. The retaining ring 1 is secured to the connecting protruding ring 12 and the corresponding groove of the external device by a split ring, thereby achieving a fixed connection of one side of the retaining ring 1 on the external device and thus fixing one side of the internal forming positive mesh device. The other side is fixed to the side of the pad sleeve 5 by a threaded post, thereby achieving a fixed connection of the internal forming positive mesh structure on the external device.

[0026] In actual operation, molten plastic enters from one side of the baffle ring 1, passes through the guide and transition of the receiving sleeve 2, and enters the area of ​​the positive mesh structure 3. Under the action of the positive mesh structure 3, it combines with the steel skeleton to form a shape, and finally exits through the connecting sleeve 4 and the gasket 5, completing the internal forming process of the steel skeleton plastic composite pipe.

[0027] Because this invention adopts a split design, eliminating the traditional connecting rib structure, the fusion state of the inner and outer plastic layers is better when the molten plastic passes through the receiving area, avoiding pipe forming quality problems caused by the presence of connecting ribs. At the same time, the thickened main body 31 improves the structural strength and service life of the equipment, ensuring production stability and product quality, and effectively solving the problems existing in the prior art.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
