Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline processing, in particular to a heating and expanding device for PE pipeline production. Background Art
[0002] During the production process of PE pipelines, heating and expansion is an important technological step. Especially when manufacturing certain types of PE pipes, such as heat shrinkable sleeves or pipes with specific size and performance requirements, the preformed PE pipe is heated above the softening point and then expanded to the required diameter through internal or external pressure. However, when existing equipment is used for processing, a common problem is that as the pipeline rotates and expands, the pipelines at both left and right ends may become eccentric due to changes at one end, resulting in uneven expansion of the pipeline. Moreover, due to the heating process, abnormal depressions or protrusions may occur in the pipeline under the state of unbalanced air pressure, affecting the expansion quality.
[0003] Therefore, in view of the above problems, a heating and expanding device for PE pipeline production is now developed. Content of the Utility Model
[0004] In order to overcome the shortcomings that as the pipeline rotates and expands, the pipelines at both left and right ends may become eccentric due to changes at one end, resulting in uneven expansion of the pipeline, and due to the heating process, abnormal depressions or protrusions may occur in the pipeline under the state of unbalanced air pressure, affecting the expansion quality of the existing device, the utility model provides a heating and expanding device for PE pipeline production.
[0005] The technical solution of the utility model is: a heating and expanding device for PE pipeline production, which includes a mounting seat. A driving component is arranged on the upper side of the right part of the mounting seat. An installation column is installed on the output shaft of the driving component. An expanding component is arranged on the installation column, and the expanding component is used for slowly expanding the pipeline. A heating element is arranged on the expanding component. The upper side of the left part of the mounting seat is connected with a mounting frame. A clamping component for clamping and fixing the pipeline is arranged on the upper part of the mounting frame. Three positioning components are arranged on the right side of the mounting frame, and the positioning components are used for positioning the center of the pipeline. A suction and pressure mechanism is arranged on the left side of the driving component, and the suction and pressure mechanism is used to assist the pipeline to expand evenly and prevent abnormal protrusions or depressions from occurring in the pipeline.
[0006] Furthermore, the suction and pressure mechanism includes an installation cylinder. The left side of the driving component is bolted with the installation cylinder. Three ventilation frames are installed on the installation cylinder. An air suction port is opened on the installation cylinder, and the air suction port corresponds to the position of the corresponding ventilation frame.
[0007] Further, it further includes a supporting mechanism. The supporting mechanism includes an installation platform. The upper side of the left part of the installation seat is connected with the installation platform. A lead screw is threadedly connected to the installation platform. The top of the lead screw is connected with a supporting tray. The supporting tray is used for centrally supporting the pipeline to prevent the middle part of the pipeline from dropping and deforming downward.
[0008] Further, the left ends of the expansion plates of the expansion assembly are all arc-shaped structures to prevent damage to the pipeline during the expansion process.
[0009] Further, a rib plate is connected between the installation frame and the installation seat.
[0010] Further, exhaust pipelines are connected to the right sides of the ventilation frames.
[0011] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0012] The present utility model is relatively simple to use. Relying on the cooperation of the positioning component and the clamping component, it avoids the eccentricity problem on the left and right sides of the pipeline and maintains the overall stability of the pipeline. As the driving component and the expansion component operate, the pipeline starts to be heated and expanded. During this process, through the cooperation of the suction port and the ventilation frame, the internal and external heating pressure balance can be always maintained, thereby preventing the pipeline from having abnormal protrusions or depressions, which affect the final effect of the pipeline heating and expansion.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The present utility model will be further described below with reference to the embodiments shown in the drawings.
[0019] Embodiment 1
[0020] A heating and expanding device for PE pipe production, as Figure 1 and Figure 2 shown, includes a mounting base 1. On the upper side of the right part of the mounting base 1, a driving component 2 is arranged. An installation column 3 is installed on the output shaft of the driving component 2. An expanding component 4 is arranged on the installation column 3. The expanding component 4 is used for slowly expanding the pipe. A heating element is arranged on the expanding component 4. The left ends of the expansion plates of the expanding component 4 are all arc-shaped structures to avoid damaging the pipe during the expansion process. On the upper side of the left part of the mounting base 1, an installation frame 5 is connected. A rib plate is connected between the installation frame 5 and the mounting base 1. On the upper part of the installation frame 5, a clamping component 6 for clamping and fixing the pipe is arranged. On the right side of the installation frame 5, three positioning components 7 are arranged. The positioning components 7 are used for positioning the center of the pipe. On the left side of the driving component 2, a suction and pressure mechanism 8 is arranged. The suction and pressure mechanism 8 is used to assist the pipe to expand evenly to avoid abnormal protrusions or depressions on the pipe.
[0021] As Figure 1 and Figure 3 shown, the suction and pressure mechanism 8 includes an installation cylinder 81. The left side of the driving component 2 is bolted to the installation cylinder 81. Three ventilation frames 82 are installed on the installation cylinder 81. Exhaust pipes are connected to the right sides of the ventilation frames 82. An air suction port 83 is opened on the installation cylinder 81. The air suction port 83 corresponds to the position of the corresponding ventilation frame 82.
[0022] It should be noted that when processing PE pipes, this device can be used for operation assistance. First, one side of the pipe is sleeved on the expanding component 4, and the other side is inserted into the installation frame 5. The positioning component 7 is relied on to detect the placement position of the pipe to avoid the eccentricity problem on the left and right sides of the pipe. After the positioning process is completed, the clamping component 6 is relied on to position and clamp the pipe to keep the left end of the pipe stable. Then, the driving component 2 and the expanding component 4 are started. After the driving component 2 is started, it will drive the installation column 3 to rotate continuously, so that the expanding component 4 rotates synchronously with the installation column 3. During the rotation of the expanding component 4, the heating element on the expanding component 4 will start to gradually heat the pipe, making the pipe soften, so as to facilitate the expansion of the right end of the pipe. During the heating and expansion of the pipe, through the cooperation of the air suction port 83 and the ventilation frame 82, the internal and external heating pressures can be kept balanced all the time, so as to avoid abnormal protrusions or depressions on the pipe, which will affect the final effect of the pipe heating and expansion.
[0023] Embodiment 2
[0024] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown in the figure, it further includes a supporting mechanism 9. The supporting mechanism 9 includes an installation table 91. The upper side of the left part of the installation seat 1 is connected with the installation table 91. A lead screw 93 is threadedly connected to the installation table 91. The top of the lead screw 93 is connected with a supporting tray 92. The supporting tray 92 is used for centrally supporting the pipeline to prevent the middle part of the pipeline from falling downward and deforming.
[0025] It should be noted that in order to prevent the middle part of the pipeline from falling downward and deforming due to gravity during the expansion process of the pipeline, resulting in eccentricity on both sides of the pipeline, rotate the lead screw 93 according to the placement height of the pipeline to adjust the height position of the supporting tray 92, so that the top of the supporting tray 92 can contact the pipeline, thereby supporting the pipeline and improving the overall stability of the pipeline placement.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
