Description

Technical Field

[0001] The utility model relates to the technical field of PEX-A pipe extrusion equipment, and particularly relates to a bracket type flow dividing cone. Background Art

[0002] Existing flow dividing cones for producing PEX-A pipes are all "petal-shaped" flow dividing cones. As shown in Figures 1-3 , the extrusion volume of this flow dividing cone is small, the unilateral stability of the flow dividing cone is poor, and the inner pipe unilateral needs to be adjusted once a day on average. At the same time, the intermittent feeding of this flow dividing cone is not smooth, and problems such as straightening of the pipe are likely to occur. Moreover, after a long time of use, problems such as numbness and lines are likely to appear on the inner wall of the pipe. And due to the small and numerous holes, it is easy to generate accumulated materials and not easy to clean the die, which affects the quality of PEX-A pipe products. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a bracket type flow dividing cone, which has a simple structure, is beautiful and concise, has a large flow channel space and is convenient for die cleaning. It can not only improve production stability, but also solve problems such as easy straightening, numbness and lines of PEX-A pipes.

[0004] The technical solution adopted to achieve the above object of the utility model is as follows:

[0005] A bracket type flow dividing cone includes a flow dividing cone body, a flow dividing ring and connecting ribs. The flow dividing cone body penetrates through the flow dividing ring, and the flow dividing cone body and the flow dividing ring are coaxial. There are multiple connecting ribs, and all the connecting ribs are located between the flow dividing cone body and the flow dividing ring. The multiple connecting ribs are evenly distributed along the circumferential direction, and the center of the circle of the circumferential direction is on the axis of the flow dividing cone body. Each connecting rib is fixedly connected to the flow dividing cone body and the flow dividing ring respectively.

[0006] The flow dividing cone body includes a first cone section and a second cone section. The first cone section is cylindrical, the second cone section is conical, one end face of the first cone section is connected to the large end face of the second cone, and the flow dividing ring is located outside the first cone section.

[0007] The connecting rib is in the structure of an inclined parallelepiped. Two relatively parallel faces of the connecting rib are rhombuses, and the other four faces of the connecting rib are parallelograms. Each of the two rhombus-shaped faces of each connecting rib is connected to the outer wall surface of the first cone section and the inner wall surface of the flow dividing ring respectively. One diagonal line of each rhombus-shaped face of each connecting rib is parallel to the axis of the first cone section.

[0008] The diagonal line connecting a group of acute-angled diagonals on each rhombus-shaped face of each connecting rib is parallel to the axis of the first cone section.

[0009] The two vertices of each rhombus-shaped face of each connecting rib connected to the diagonal line parallel to the axis of the first cone section are flush with the two end faces of the flow dividing ring respectively.

[0010] The connecting ribs are flat.

[0011] One end surface of the diverter ring is flush with the end surface where the first cone section and the second cone section are connected.

[0012] Compared with the prior art, the beneficial effects and advantages of the utility model are:

[0013] 1. The splitter cone is a bracket-type splitter cone. Six diamond-shaped "ribs" evenly distributed in the ring replace the porous "petal shape" to increase the flow channel space, change the flow channel mode, and change the oblique hole flow channel of the old splitter cone to the straight hole flow channel of the bracket-type splitter cone, so as to increase the extrusion volume, facilitate mold cleaning for production personnel, reduce the labor intensity of production personnel stopping to clean the mold, and solve the quality problems of PEX-A pipes such as straightening and numbness.

[0014] 2. The flow channel of the diverter cone decreases first and then increases, that is, the material first flows from the cylindrical surface to the conical surface, and then flows from the conical surface to the cylindrical surface. At the same time, the melt flow ratio is increased, the stability of extrusion is improved, and the problem of intermittent material feeding can be effectively solved.

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] The structure of the bracket type diverter cone provided in this embodiment is as followsFigures 4-7 As shown, it includes a flow splitting cone 1, a flow splitting ring 2 and connecting ribs 3.

[0025] As Figures 5-6 shown, the flow splitting cone 1 includes a first cone section 101 and a second cone section 102. The first cone section 101 is cylindrical, and the second cone section 102 is conical. One end face of the first cone section 101 is connected to the large end face of the second cone section 102.

[0026] The flow splitting cone 1 penetrates through the flow splitting ring 2, and the flow splitting cone 1 and the flow splitting ring 2 are coaxial. The flow splitting ring 2 is located outside the first cone section 101, and one end face of the flow splitting ring 2 is flush with the end face where the first cone section 101 is connected to the second cone section 102.

[0027] As Figure 7 shown, there are 6 connecting ribs 3, and all 6 connecting ribs 3 are located between the flow splitting cone 1 and the flow splitting ring 2. The 6 connecting ribs 3 are evenly distributed along the circumferential direction, and the center of the circle of the circumferential is on the axis of the flow splitting cone 1. The connecting ribs 3 are flat oblique parallelepiped structures. Two relatively parallel faces of the connecting ribs 3 are rhombic, and the other four faces of the connecting ribs 3 are parallelograms.

[0028] Each of the two rhombic faces of each connecting rib 3 is respectively connected to the outer wall surface of the first cone section 101 and the inner wall surface of the flow splitting ring 2. The diagonal line connecting a set of acute-angled diagonals on the rhombic face of each connecting rib 3 is parallel to the axis of the first cone section 101. The two vertices of the rhombic face of each connecting rib 3 connected to the diagonal line parallel to the axis of the first cone section 101 are respectively flush with the two end faces of the flow splitting ring 2.

[0029] The flow splitting cone is separated into 6 flow channels by the connecting ribs 3, increasing the flow channel space. And each flow channel is a straight-hole type flow channel. The upper half of each flow channel is an inverted cone shape, and the lower half of each flow channel is a cone shape. That is, the material in each flow channel first flows from the cylindrical surface to the conical surface, and then from the conical surface to the cylindrical surface, increasing the melt flow ratio, improving the stability of extrusion, and being able to effectively solve the problem of intermittent poor feeding.
