Abstract
The invention discloses an extrusion flow channel of a pipeline extruder. The extrusion flow channel is connected with a feeding hole, a spiral body and a pipe outlet; the spiral body is a cylindrical body provided with spiral open flow channels in the surface; the spiral open flow channels are radially arranged; a pipeline is axially extruded from the pipe outlet. The extrusion flow channel changes a conventional mode of axial movement of a material during pipeline extrusion and enables the material to radially move, thereby greatly enhancing the radial strength of the pipe material.
Description
Technical field
The present invention relates to a kind of extruder, more specifically, relate to a kind of extrusion channel of pipe extruder.
Background technology
The processing molding method of plastic pipe is mainly undertaken by the method for extrusion molding, its technological process is extruded through extruder plasticizing usually, extrusion die is shunted, sizing cools, traction, 5 operations such as fixed length cutting, wherein the effect of extrusion die mainly makes the plastic material being in plastifying fusion state form the material embryo of required size by processes such as expansion, shunting, compressions.The version of current plastic pipe is mainly stent-type, blue formula and T-shaped mould.
In the whole technological process of plastic pipe, the overall flow direction of material is consistent with the axis of tubing, the strand of easy generation macromolecular material is along tubing axial orientation, thus produce the anisotropy of pipe material, cause material higher than radial strength along tubing axial strength, this phenomenon is very unfavorable to the application of Pressurized Plastic Pipes, if because the pressure pipeline radial load of advocating of in use bearing.
Summary of the invention
The object of the invention is to, find a kind of pipeline can preparing high radial power.
According to above object, first the present invention provides a kind of extrusion channel of pipe extruder, connects feeding mouth, conveyor screw and outlet spout successively, and described conveyor screw is the cylinder that a surface has that runner opened by spiral, spiral is opened runner and is radially arranged, and described outlet spout is from axially extruding pipeline.
Described feeding mouth from spirochetal side pan feeding, become with the direction of outlet spout 90 degree vertical.
Described spiral is sneaked away the long caliber 8 ~ 16 times for pipeline.
Described spiral is sneaked away and is had 3 ~ 5 spirals.
The invention has the advantages that, tube extrusion grinding tool runner is redesigned, changes stream Way in into side pan feeding, devise simultaneously one end along tubing axial flow spiral open runner, change the single form flowed vertically of material.
By changing the structural form of mould, making the plastics of molten condition along tubing Radial Flow, thus adding the radial strength of tubing.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of prior art.
Detailed description of the invention
The present invention is further described below in conjunction with the drawings and specific embodiments.Unless stated otherwise, the present invention adopts reagent, equipment and method are conventional commercial reagent, equipment and the conventional method used of the art.
Embodiment 1
As shown in Figure 1, a kind of extrusion channel of pipe extruder is disclosed, connect feeding mouth, conveyor screw and outlet spout successively, conveyor screw is the cylinder that a surface has that runner opened by spiral, spiral is opened runner and is radially arranged, and described outlet spout is from axially extruding pipeline, and feeding mouth is from spirochetal side pan feeding, described spiral is sneaked away the long caliber 16 times for pipeline, and described spiral is sneaked away and had 5 spirals.
Embodiment 2
As shown in Figure 1, a kind of extrusion channel of pipe extruder is disclosed, connect feeding mouth, conveyor screw and outlet spout successively, conveyor screw is the cylinder that a surface has that runner opened by spiral, spiral is opened runner and is radially arranged, and described outlet spout is from axially extruding pipeline, and feeding mouth is from spirochetal side pan feeding, described spiral is sneaked away the long caliber 10 times for pipeline, and described spiral is sneaked away and had 3 spirals.
Embodiment 3 compliance test result
Comparative example: adopt traditional extrusion channel, as shown in Figure 2.
The extrusion channel of embodiment 1 is extruded together with the extrusion channel of comparative example the pipeline of same pipe diameter size, the radial strength extruding the pipeline obtained through testing example 1 is 2.5 times that comparative example extrudes the radial strength of the pipeline obtained.
