Description

Technical Field

[0001] The utility model relates to the technical field of PE water supply pipe production, in particular to an automatic traction and turnover mechanism for processing large-diameter PE water supply pipe production. Background Art

[0002] PE water supply pipe is made of special polyethylene as raw material and is extruded by a plastic extruder in one step. It is used in urban water supply networks, irrigation and water diversion projects, and agricultural sprinkler irrigation projects. It is particularly suitable for plastic pipes that are resistant to alkali and corrosion environments.

[0003] In order to facilitate the connection between PE water supply pipes and increase the sealing of the pipes in the subsequent use process, flanges need to be set at the ends of PE water supply pipes. However, in the process of pressing the flanges, due to the heavy weight of large-diameter PE water supply pipes, a sling is usually required, which increases the difficulty of feeding and prolongs the time of flange pressing.

[0004] In addition, since the material of the PE water supply pipe has a certain toughness, if the end of the PE water supply pipe is pressed into a flange only by horizontal pressing, it is easy to cause uneven pressing and reduce the sealing effect. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides an automatic traction and flipping mechanism for the production of large-diameter PE water supply pipes, which overcomes the deficiencies of the prior art and effectively solves the problems of long flange pressing time and uneven pressing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A double-headed cylinder is arranged on the top of the processing table, and both ends of the piston rod of the double-headed cylinder are hinged with cross rods, and the inner wall of one end of the cross rod is rotatably connected to a positioning pulley.

[0009] Preferably, a mounting frame is welded to the outer wall of the processing table, and the lifting cylinder is fixedly connected to the top and bottom outer walls of the mounting frame by bolts.

[0010] Preferably, the inner wall of the mounting frame is provided with symmetrically distributed guide pillars, and the positioning sleeve and the flange mold frame are both slidably connected to the outer walls of the guide pillars.

[0011] Preferably, a connecting rod is welded to one side of the outer wall at the top of the mounting frame, and the axial column of the cross rod is installed on the outer wall at one end of the connecting rod.

[0012] Preferably, the top outer wall of the processing table is equipped with symmetrically distributed guide wheels, and the top outer wall of the guide wheel is slidably connected to a PE water supply pipe.

[0023] In this embodiment, the PE water supply pipe can be directly pushed into one side of the flange mold frame 6 by driving the push plate 3 to move through the first hydraulic push rod 2. After the lifting cylinder 4 drives the two sets of positioning sleeves 5 and the flange mold frame 6 to close, the flange pressing plate 8 is pushed by the second hydraulic push rod 7 to extrude the PE water supply pipe, thereby realizing the flange pressing and forming of the end of the PE water supply pipe, reducing the difficulty of feeding and saving the time of flange pressing.

[0024] Example 2, refer to Figure 2-3 An automatic traction and flipping mechanism for the production of large-diameter PE water supply pipes. The inner wall of the bottom of the processing table 1 is fixedly connected to a servo motor 9 by bolts, and the output shaft of the servo motor 9 is connected to a traction wheel 10. A double-headed cylinder 11 is arranged on the top of the processing table 1, and both ends of the piston rod of the double-headed cylinder 11 are hinged with a cross rod 12, and the inner wall of one end of the cross rod 12 is rotatably connected to a positioning pulley 13.

[0025] In this embodiment, by extending the piston rod through the double-head cylinder 11, the positioning pulley 13 at the bottom of the cross rod 12 can be controlled to be close to the PE water supply pipe. When the servo motor 9 drives the traction wheel 10 to rotate, the automatic flipping of the PE water supply pipe is realized, thereby ensuring the balanced pressure on the end of the PE water supply pipe, improving the quality of the flange forming at the end of the PE water supply pipe, and increasing the sealing effect of the flange.
