Background technique
Insulation to high-voltage circuit and high voltage installation is the necessary component part of high-voltage technology.In transformation and match In electric equipment, also there is very high technical requirement to insulator.Usually using ceramic insulator as insulator.
In order to manufacture such insulator, ceramic material is used, which is configured to by extrusion forming process So-called matrix (Hubel).Then, the expectation that matrix (also known as blank) is directed to respective application requirement is given by Cutting Process Geometry.After drying, usually also for example apply glaze in dipping bath.Then, processed blank is fired And obtain insulator.The density of material of this matrix plays a significant role in terms of the quality of insulator in the future.In order to produce Raw high density of material, especially with the so-called vacuum extruding equipment being usually vertically oriented.
Using bigbore insulator is arrived in high voltage and extra-high voltage equipment, have in 200mm to 500mm range Diameter interior or until 600mm, and it has length in the range of as unit of rice.
This vertical vacuum extruding equipment is known by 00 0,001 258 775 B of DE.The equipment have main cylinder pressure, The mouth of extrusion head and cylinder shape.What the process and major function of the mouth of cylinder shape can be published from VEB publishing house " Technologie der Keramik (ceramic technology) " volume 2, the 165-166 pages is learnt.Here, ceramic material is conveyed To the extruder and evacuation arranged vertically.Then, ceramic material is compressed and is passed through and extruding by extruding screw and extrusion head The adjacent mouth of head leaves extruder.The ceramic material tearing of mouth is left in order to prevent, and there are so-called bases for mouth lower section Object table, the substrate of substrate stage receive ceramic material to constitute matrix and with the submitting speed sync of matrix vertically moving Leave mouth.
Using conventional method, making has the especially bigbore matrix of the high material degree of compression can only be limitedly real It is existing.
Summary of the invention
In view of this, a kind of for manufacturing the method and one of especially bigbore matrix the task of the present invention is providing Kind extrusion equipment, can manufacture whereby with highdensity bigbore matrix.In addition, the task of the present invention is provide a kind of tool There is highdensity matrix.
The task with feature described in claim 1 according to the present invention by being used to manufacture especially bigbore matrix Method solve.Matrix is made of ceramic material and has first diameter.Here, first diameter describes the maximum of matrix Overall diameter simultaneously thus defines base diameter.
In the method, ceramic material is pressed through mouth and is received by substrate of substrate stage, and the substrate of substrate stage is to leaving mouth Material apply counter-pressure.Specifically, mouth is especially tapered in expansion along vertical direction since minimum interior diameter Width, which arrives, sends out diameter, wherein interior diameter is less than base diameter.Here, ensuring mouth in end by the counter-pressure of substrate of substrate stage It is in the region of the submitting diameter through widening and is filled uniformly with material.
Test proves, thus realizes the particularly good degree of compression in unexpected mode.Here, the degree of compression is decisive Ground is determined by the minimum interior diameter of mouth, this is because material experienced the compression of top herein.Although (mouth quilt Broadening) but the degree of compression is subsequent is still able to maintain.Therefore, the material of plasticity has a kind of Memorability in terms of the degree of compression.Will not or The resilience or relaxation caused by widening due to taper only occur to a small extent.This is indicated that, with the base routinely made Body is compared, and the contract with dry rate during drying is substantially reduced.In the matrix routinely made, it is dry during contract with dry rate be about 3% (to press Stereometer).In using matrix made of new method described herein, the contract with dry rate during this drying is reduced to about 1%.By In counter-pressure, while also achieving and (increasing compared to interior diameter) desired base diameter.
The advantages of design scheme is considered as the bigbore matrix that easy production has high density of material.This is just Lead to (counter-bending) intensity in finished product insulator after firing with higher machinery.Test proves, (with routinely make Matrix/insulator is compared) intensity can be improved about 20% to 25%.This allows to consider to have when designing insulator higher again Intensity, and in the identical situation of intensity value, use the smaller or thinner insulator with less material.Thus it just obtains Apparent material is saved.In general, which improves matrix and the in the future quality of insulator.In addition, thus also reducing Rejection rate in substrate manufacturing process.In addition, this also allows to make the matrix with very big diameter, and use so far Conventional method can not then manufacture this matrix with very big diameter (with sufficient intensity).
In method, a variety of mouth variants of diameter are suitably able to use with different (minimum) interior diameters and sent out. Here, minimum interior diameter has the value preferably within the scope of 350mm to 500mm in all variants, especially have Value between 430mm and 460mm.The advantages of design scheme be the variant of mouth is carried out it is consistent and easy Assembly.
