Description
Technical field
The present invention relates to compressor terminal and manufacture method thereof, specifically a kind of sealing glass for compressor terminal and manufacture method thereof.
Background technology
The metal of fully closed domestic air conditioning and refrigerator and glass-sealed connection terminal, this product is the iron covering be stamped to form by soft steel, and 2-4 root SUS446 or 4J28 diameter are that the draw point of 2.3 millimeters or 3.2 millimeters is formed by the sealing-in at the temperature of about 1000 degree of seal glass frit.
Above manufacturing process relative maturity, but the glass insulation of two separate types all can be adopted to combine in the compressor terminal manufacturing processed that current all band glass is climbed, again through high temperature sintering by two independently glass insulator fuse together and form glass and to climb and certain shape, to meet the requirement of insulation distance, the glass shape of this separate type is simple, length is less, so technique is easy to realize.
But the glass frit being divided into two sections is combined, there are two glass physical interfaces contacted with each other, because the physical surface of glass may exist impurity, organic contamination, surface crater, unfairness etc. state, like this, when sealing-in product, these two physical interfaces may because of the various defect in surface, bubble is produced during fusion, the problems such as crackle, thus the properties affecting product, comprise outward appearance, stopping property, electric durability etc.
Summary of the invention
Technical problem to be solved: the object of the invention is to provide a kind of glass frit and its manufacture method thereof of the global formation for compressor terminal, without physical interface and bubble in its glass frit, crack defect.
Technical scheme: a kind of sealing glass for compressor terminal, is characterized in that: described sealing glass is a kind of glass frit of global formation.
Its special making method step is: put into by glass powder in multi-cavity stepped start-stop system press, is pressed into two sections of difform one base substrates, described one base substrate is placed in sintering oven, 650 degrees Celsius of lower pre-burnings 60 minutes, takes out naturally cooling, for subsequent use.
Beneficial effect of the present invention: the present invention is owing to have employed technique scheme, and the sealing glass in compressor terminal is a kind of glass frit of global formation.There is not the impurity in two glass physical interfaces contacted with each other, organic contamination, surface crater, unfairness etc. state, therefore, glass frit is put into when sintering oven fuses after putting into iron covering and draw point and can not be produced bubble, the phenomenons such as crackle, the properties of product, comprise outward appearance, stopping property, electric durability is good.

Embodiment
Below in conjunction with embodiment, the invention will be further described.
For a sealing glass for compressor terminal, its special character is: described sealing glass is a kind of glass frit of global formation.
Its special making method step is: put into by glass powder in multi-cavity stepped start-stop system press, is pressed into two sections of difform one base substrates, described one base substrate is placed in sintering oven, 650 degrees Celsius of lower pre-burnings 60 minutes, takes out naturally cooling, for subsequent use.
See Fig. 1,2, the metal of fully closed domestic air conditioning and refrigerator and glass-sealed connection terminal, this product is the iron covering be stamped to form by soft steel, and 2-4 root SUS446 or 4J28 diameter are that the draw point of 2.3 millimeters or 3.2 millimeters is formed by the sealing-in at the temperature of about 1000 degree of seal glass frit.Its main Problems existing is: as shown in Figure 1, 2, and its glass frit is formed by the first glass frit 1 and the second glass frit 2 sealing-in.
See Fig. 3,4, the overall glass frit 3 of the 3rd glass of the present invention or the 4th overall glass frit 4 are a kind of global formations.
Below to adopting the compressor terminal of prior art and product of the present invention to do further detailed comparisons's explanation.
Experiment 1(separate type glass combination, prior art compressor terminal): glass powder separate type is shaping, and---pre-burning---assembles---sintering---verification test.
Experiment 2(integral glass, adopts the compressor terminal of invention): glass powder monoblock type is shaping, and---pre-burning---assembles---sintering---verification test.
Material used: model is 500 grams, the glass powder of GST90, model is 2K32 terminal iron covering 100 used, the SUS446 draw point of diameter 3.2 mm length 36.5 millimeters 300, and sintering fixture 12 overlaps, and is divided into two groups and tests.
Equipment: single chamber press one, stepped start-stop system press one, sintering oven 2,20 times of magnifying glasses, microhardness tester, super resistance instrument, proof voltage survey meter, mould 4 overlaps
Experiment 1: first 500 grams of glass powder are divided into 2 parts, wherein puts in the press of single chamber for 250 grams, suppresses each 200 base substrates as following shape respectively, pre-burned for subsequent use under 650 degree.Be designated sample 1.
Experiment 2: other 250 grams of glass powder are put in multi-cavity stepped start-stop system press, the base substrate of compacting less than 200 shapes, then pre-burned for subsequent use under 650 degree.Be designated sample 2.
Cleaned 100 iron coverings and 300 draw points are divided into each 50 of two halves, then the glass frit of sample 1 and sample 2 is put into iron covering and draw point respectively, put into sintering oven simultaneously, 1000 degrees Celsius of lower sealings by fusing 90 minutes, take out terminal sample respectively, correspondence is designated experiment 1 and experiment 2.
Experimental result: adopt the glass sintering product that above two kinds of modes are shaping, from appearance and indifference.
By above sample through plating, for subsequent use after making finished product after the operations such as welding.Be labeled as the sample of experiment 1 and experiment 2.
Get out 20 times of magnifying glasses, super resistance instrument, withstands voltage tester, cutting machine, sand paper etc., respectively get the finished product 10 of experiment 1 and experiment 2, first check air entrapment by the method for X-ray transmission, cut from glass blister side with cutting machine after finding out defective, then use sand papering for subsequent use.
Following phenomenon is observed respectively under 20X microscope.
Table 1, separate type glass combination and integral glass air entrapment contrast:
。
By ready-made remaining 40 laboratory samples, first check glass surface, and then by the electric property of super resistance instrument and proof voltage survey meter test products.Outcome record is as table 2.
Table 2, separate type glass combination and integral glass electric performance test Comparative result:
。
Test result illustrates, there is not inner physical interface in appearance, its outward appearance, air entrapment with the compressor terminal of molding in integral glass frit manufacture, and electrical property is obviously better than the product using Separated type combination glass.
In the present invention, due to the projection of centre, therefore the drawing method of routine cannot complete, therefore the present invention adopts the method for segmentation stepped start-stop system compression molding, and the method and apparatus suppressed by stepping is synchronously advanced in vertical both direction respectively, form overall vitreous structure, this vitreum shape has a variety of, but basic innovation is to unite two into one, and no longer adopts the form of separate type.
The present invention is only limitted to absolutely not these examples.The foregoing is only the good embodiment of the present invention, only for describing the present invention, the restriction to scope of the present invention can not be interpreted as.The present invention is it is emphasised that improvement in a kind of glass powder molding in integral and the product performance brought thus; be not limited to certain specific shape and size; it should be noted that; all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
