Description

Technical Field

[0001] The utility model relates to the technical field of pipe production, in particular to a forming device for composite plastic pipes. Background Art

[0002] Plastic pipes are chemical building materials made of high-tech composites, and chemical building materials are the fourth largest category of new building materials in contemporary times after steel, wood, and cement. Plastic pipes are mainly used for piping, drainage, exhaust, and sewage treatment in tap water supply systems of housing buildings. Plastic pipes are processed by extrusion in a pipe making machine. During the entire pipe processing and molding process, after the pipes are initially processed and molded, the entire pipe needs to be cooled and polished. The existing molding devices for composite plastic pipes usually cannot effectively pre-cool the plastic pipes during the molding production of the pipes, but directly cool them by spray cooling, which increases the deformation of the plastic pipes. At the same time, the inside and outside of the pipes cannot be fully and evenly cooled, so there is a temperature difference, which leads to stress concentration and affects the quality of the pipes.

[0003] Therefore, the utility model provides a forming device for composite plastic pipes. Utility Model Content

[0008] Furthermore, a first cooling port and a second cooling port are respectively provided on the surface of the outer cooling cover and the inner cooling roller, and an inspection port is fixedly provided on the outer surface of the mounting side plate.

[0010] Furthermore, the outer cooling cover is connected to the mounting seat, and the outer cooling cover is arranged in an arc shape as a whole. At the same time, the outer cooling cover is located below the inner cooling roller. The inner cooling roller is arranged as a hollow roller body, and the outer end is fixedly connected to the inner surface of the tail seat.

[0011] Furthermore, an air pump mechanism is provided at the connection position between the outer cooling cover and the mounting seat, and an air pump mechanism is provided at the connection position between the inner cooling roller and the tailstock.

[0012] Furthermore, the first cooling port is longitudinally opened along the surface of the outer cooling cover, and multiple groups of air flow nozzles are arranged side by side on the inner side thereof, while the second cooling port is spirally distributed along the surface of the inner cooling roller and is arranged as a honeycomb opening.

[0013] Furthermore, the air guide cover is provided in an arc-shaped cover body and is movably connected to the top of one side of the shaft and the outer cooling cover by flipping.

[0026] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0027] See Figure 1-4 As shown, a forming device for composite plastic pipes includes a tailstock 1 and an outer baffle 2 fixedly connected, a through opening 3 fixedly opened on the surface of the outer baffle 2, and a cooling forming structure 4 fixedly connected to the surface of the tailstock 1, and the cooling forming structure 4 is also located on the inner side of the outer baffle 2.

[0028] In the embodiment of the present invention, the cooling molding structure 4 includes a fixedly connected mounting side plate 5 and a mounting seat 6 on its inner surface, the inner side of the mounting seat 6 is fixedly connected to an outer cooling cover 7, and the inner side of the outer cooling cover 7 is fixedly provided with an inner cooling roller 8, and the top of one side of the outer cooling cover 7 is movably connected to a guide cover 9, and the surfaces of the outer cooling cover 7 and the inner cooling roller 8 are respectively provided with a first cooling port 10 and a second cooling port 11, and the outer surface of the mounting side plate 5 is fixedly provided with an inspection port 12, and the outer end of the mounting side plate 5 is fixedly connected to the surface of the tail stock 1 at the same time, and the mounting seat 6 is hollow inside. The mounting side plate 5 and the mounting seat 6 are relatively arranged in two groups on both sides of the inner side of the tail stock 1, and the mounting side plate 5 and the mounting seat 6 are conveniently connected and fixed to the outer cooling cover 7, and the mounting seat 6 is conveniently used to install the air pump mechanism provided in conjunction with the outer cooling cover 7.

[0029] The outer cooling hood 7 is connected to the mounting seat 6, and the outer cooling hood 7 is arranged in an arc shape as a whole. At the same time, the outer cooling hood 7 is located below the inner cooling roller 8. The inner cooling roller 8 is arranged as a hollow roller body, and the outer end and the inner surface of the tail stock 1 are fixedly connected. The connection position of the outer cooling hood 7 and the mounting seat 6 is equipped with an air pump mechanism, and the connection position of the inner cooling roller 8 and the tail stock 1 is equipped with an air pump mechanism. The arc-shaped outer cooling hood 7 is used to achieve the effect of limiting and surrounding the external pipe from the bottom position, and the inner cooling roller 8 is used to achieve the effect of embedding the external pipe to surround and limit it. At the same time, the outer cooling hood 7 is arranged in an arc shape to achieve the effect of guiding the cooling airflow.

[0030] The first cooling port 10 is longitudinally opened along the surface of the outer cooling cover 7, and multiple groups of air flow nozzles are arranged side by side on the inner side thereof, while the second cooling port 11 is spirally distributed along the surface of the inner cooling roller 8 and is arranged as a honeycomb opening. The effect of conveying cooling airflow is achieved through the first cooling port 10 and the second cooling port 11.

[0031] When cooling and forming the external pipe, the external pipe is extruded and formed by the external extrusion device, and directly enters the device through the through port 3, forming a sleeve state with the external cooling cover 7 and the internal cooling roller 8. The external cooling cover 7 surrounds the bottom position of the pipe, and the internal cooling roller 8 is embedded in the external pipe. After that, the air pump mechanism of the external cooling cover 7 and the internal cooling roller 8 is started, driving the external air flow to be ejected from the first cooling port 10 and the second cooling port 11, and pre-treating and cooling the inside and outside of the external pipe at the same time;

[0032] The air guide cover 9 is arranged in an arc-shaped cover body, and is connected to the top of one side of the outer cooling cover 7 by flipping the shaft body. The air guide cover 9 is used to guide the cooling air flow. At the same time, the flipped air guide cover 9 makes it easy for the user to adjust the angle between it and the outer cooling cover 7.

[0033] When the external airflow is ejected from the first cooling port 10 and the second cooling port 11 to pre-treat and cool the inside and outside of the external pipe at the same time, the user can reverse and adjust the angle of the guide cover 9 in advance, so that the cooling airflow forms a circulating guide in the outer cooling cover 7 and the inner cooling roller 8, ensuring sufficient cooling and forming of the inside and outside of the pipe.
