Abstract
The utility model relates to a tube extrusion die which comprises a feeding die. A feeding port and an annular groove are formed on the feeding die, raw material enters the annular groove through the feeding port during feeding, and at least two discharging holes are formed on the discharging end surface of the annular groove. The tube extrusion die has the advantages that by improving the discharging holes on the feeding die and adding designs capable of effectively controlling the wall thickness of tubes, not only the wall thickness of the processed tubes can be very uniform, but also the production efficiency is greatly improved, thus saving both the time and the labor.
Description
Technical field
The utility model relates to a kind of tubing extrusion die.
Background technology
A lot of tubing extrusion dies are arranged in the market, can process the tubing that various mono-layer tubes, bimetallic tube etc. are applied to every field.Total institute is known, and the control for tube wall thickness in the time of processing tubing is even more important, and the tube wall thickness that much processes is uneven, has a strong impact on its performance.In order to control the wall thickness of tubing better, a lot of manufacturers all are regularly the tubing that section inspection processes, and find that wall unevenness is even, adjust from mould again, and so forth, had a strong impact on production efficiency, and tubing itself also only had to the improvement on the not half, this point is far from being enough, therefore, must improve from the tubing extrusion die, overcome the defective in the original production, enhance productivity.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that existing tubing extrusion die exists in the above-mentioned background technology, provide a kind of improved tubing extrusion die.
The technical scheme that the utility model adopted is: a kind of tubing extrusion die, comprise that one offers the charging mould of annular groove, charging mould central interior is provided with plug, also be provided with package cover on the described charging mould, form a toroidal cavity between package cover and the annular groove, also be provided with charging aperture on the described package cover, raw material enters toroidal cavity by charging aperture during charging, the discharging end face of described charging mould is provided with at least two discharge openings that are communicated with described toroidal cavity, the pore size of discharge opening be according to discharge opening apart from the distance of charging aperture from the near to the remote rule and increase progressively gradually, during discharging, the raw material in the toroidal cavity outwards flows out by discharge opening.
Further, the discharging end face of annular groove described in the utility model is provided with at least four discharge openings that distribute symmetrically and evenly.
Further, the pore size of discharge opening described in the utility model be according to discharge opening from the distance of charging aperture from the near to the remote rule and increase progressively gradually, because near the material flow the near more discharge opening of charging aperture is big more, the flow of raw material is more little near charging aperture discharge opening far away more, so such design could guarantee that the material flow size that each discharge opening comes out is identical as much as possible, could guarantee that the wall thickness that processes tubing reaches even.
Further, discharging end face outer setting described in the utility model has and discharging end face all-in-one-piece cambered surface buffering slope, cushion sloping central authorities and be provided with taper punishment in advance port, cambered surface buffering slope can be played the effect of buffering to the raw material that comes out in the discharge opening, make it slowly enter the punishment in advance port, further control the even of material flow along cambered surface.
Further, in order to control the tubing of tube wall thickness and processing different inner diameters better, charging mould described in the utility model is socketed with water conservancy diversion mould and plug die successively by plug.
The beneficial effects of the utility model are: the utility model tubing extrusion die is by to the improvement in charging mould top discharge hole and increased some and can effectively control the tubing design of Wall Thickness, make that not only the tube wall thickness that processes is very even, and improved production efficiency greatly, time saving and energy saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the structure distribution schematic diagram in the utility model charging mould top discharge hole.
Among the figure: 1. charging mould, 2. charging aperture, 3. annular groove, 4. discharging end face, 5. discharge opening, 6. buffering slope, 7. punishment in advance port, 8. plug, 9. package cover.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, the embodiment of the utility model tubing extrusion die shown in Figure 2, comprise that one offers the charging mould 1 of annular groove 3, charging mould 1 central interior is provided with plug 8, also be provided with package cover 9 on the described charging mould 1, form a toroidal cavity between package cover 9 and the annular groove 3, also be provided with charging aperture 2 on the described package cover 9, the discharging end face 4 of charging mould 1 is provided with 12 symmetries and equally distributed discharge opening 5, be less than aperture from charging aperture 2 discharge opening 5 far away more from the aperture of the near more discharge opening 5 of charging aperture 2, discharging end face 4 outer setting have and discharging end face 4 all-in-one-piece cambered surfaces buffering slope 6, cushion sloping 6 central authorities and be provided with taper punishment in advance port 7, plug 8 runs through punishment in advance port 7.In order to reach better effect, can also socket water conservancy diversion mould and plug die on the described charging mould 1.
Raw material enters toroidal cavity by charging aperture 2, then evenly outwards flow out in 12 discharge openings 5 from the discharging end face 4, by slowly flowing to discharging port 7 after 6 bufferings of cambered surface buffering slope, enter the uniformity coefficient that the water conservancy diversion mould is further stablized raw material again, pass through plug die at last.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
