Summary of the invention
The present invention is in view of the above fact, and it is a kind of at the glass for sealing that rolls and can keep postural stability and be not easy to produce cut or breach that its purpose is to provide.
Another object of the present invention is to provide a kind of glass for sealing easy to manufacture and manufacture method thereof.
For achieving the above object, the invention provides a kind of glass for sealing, it is characterized in that: when on horizontal plane during with the prescribed form mounting, by its center of gravity and with all each sections of this horizontal plane quadrature all form possess with the major axis of this horizontal plane parallel direction and with the flat of the minor axis of this horizontal plane orthogonal direction, and, do not possess the edge part of right angle or acute angle on the outer surface.Here, above-mentioned " prescribed form " has one situation and a plurality of situations.That is, exist: only download the situation that just satisfies above-mentioned aforementioned condition when placing on the horizontal plane and download the situation that under each posture, all satisfies above-mentioned aforementioned condition when placing on the horizontal plane with each posture of a plurality of postures in certain specific posture.In addition, " edge part that does not possess right angle or acute angle on the outer surface " is meant the situation that does not manifest the edge part of right angle or acute angle on the profile of each all section in any direction.
Glass for sealing of the present invention, owing to have flat pattern at above-mentioned end direction of principal axis, therefore when mounting during in the sealing of sealed object thing, can become in sealing portion the state that the stable posture with above-mentioned regulation falls, even thereby owing to making the sealed object thing, external force effects such as vibration tilt a little, can not tumble out from sealing yet.
In addition, glass for sealing of the present invention is owing to possess the edge part of right angle acute angle at outer surface, therefore when transporting etc. under the situation, even glass for sealing to each other or bump because of contact produces to wipe between glass for sealing and the miscellaneous part, also is not easy to produce cut or breach.
In the above-described configuration, the outer surface of glass for sealing can be made of Free Surface and non-Free Surface, and wherein, described Free Surface forms by the surface tension of melten glass, and described non-Free Surface forms by contacting with shaping dies.Free Surface is owing to be that surface tension by melten glass forms, so forms level and smooth three-dimension curved surface.In addition, therefore described non-Free Surface can become the shape of shaping dies or the surface of surface texture transfer printing owing to be to form by contacting with shaping dies.
Outer surface by the glass for sealing that above-mentioned Free Surface and non-Free Surface constitute, do not had machined surfaces such as cutting plane.That is, sealing can not produce by machinings such as cut-outs with glass, and easy to manufacture.In addition, in general, if the outer surface at glass article exists cutting plane, abradant surface, drives machined surfaces such as face, then on machined surface, be easy to generate scar or crack, become the reason of cut or breach easily, but owing to do not possess machined surface, therefore there are not these problems with glass in sealing.In addition, when melten glass sharply cools off by contacting with shaping dies, because at outer surface, especially in non-Free Surface generation compression stress, therefore can expect following effect, promptly, not only be not easy to produce scar or crack, and produce cut or breach when being not easy when transporting etc. because of contact.
Above-mentioned non-Free Surface occurs in the position that intersects with above-mentioned end axle usually.In addition, non-Free Surface can only form in a position of outer surface, also can form in a plurality of positions.For example, for example can short-axis direction relatively to two positions form non-Free Surface respectively.
Above-mentioned non-Free Surface can have arbitrary shape in the scope of the condition of the edge part that does not possess right angle or acute angle, but the whole zone of preferred non-Free Surface or a part of zone are tabular surfaces, and promptly preferred non-Free Surface has tabular surface.Thus, the formation of the shaping dies that non-Free Surface is formed is simplified, and, non-Free Surface mounting by will being formed with tabular surface is on the sealing of sealed object thing, can increase postural stability, thereby can effectively prevent to come off from sealing for the glass for sealing of sealing.
In addition, above-mentioned non-Free Surface can be an even surface, but preferably its whole zone or a part form matsurface, especially form the pears surface, promptly preferably makes non-Free Surface have matsurface, especially have a pears surface.Thus, when mounting during in the sealing of sealed object thing, glass for sealing is difficult to relative sealing portion and slides, and can effectively prevent to come off from sealing.Wherein, the preferred Ra of the roughness of the matsurface of non-Free Surface (arithmetic average roughness that " JIS B0601-1994 " regulation is arranged)=0.2 μ m～10 μ m.
In addition, for achieving the above object, the invention provides the manufacture method that drips to the glass for sealing that forms on the shaping dies by melten glass with prescribed volume.The melten glass that drips in dropping process owing to capillary effect becomes roughly spherical, but the kinetic energy when falling and being pressed on the shaping dies, making the surface that contacts with shaping dies become transfer printing has the surface of the shape or the surface configuration of shaping dies (non-Free Surface).About the surface (Free Surface) that does not contact with shaping dies, the surface configuration of the melten glass in falling sometimes (roughly spherical) can be kept original form, but in most cases, the melten glass that drips when falling kinetic energy and be pressed to result on the shaping dies, compared with the imaginary ball that the melten glass that has Yu drip has equal volume, the shape that its surface profile becomes inside side or departs to foreign side.For example, under most situations, become under the situation above Free Surface is positioned at respect to shaping dies from the inwardly square shape that departs from of the surface profile of above-mentioned imaginary ball, and under the situation that is positioned at the position, side by the surface with respect to shaping dies, become the shape that departs to foreign side from the surface profile of above-mentioned imaginary ball.No matter above-mentioned under which situation, the melten glass of falling on the shaping dies all becomes flat pattern at falling direction.
The surface of the melten glass that contacts with shaping dies not can be residual as Free Surface with its whole surface, but preferably with at least a portion surface from the top with the second shaping dies extrusion molding.Thus, the flat degree height of the glass for sealing after the shaping prevents to roll thereby further improve postural stability.
According to the present invention, can provide good and be not easy to produce the glass for sealing of cut or breach to the postural stability of rolling.
In manufacture method of the present invention, owing to dripping on the shaping dies, the melten glass with prescribed volume is shaped, therefore machining such as when carrying out the manufacturing of glass for sealing, do not need to cut off, in addition, can also make a plurality of glass for sealing continuously.Thereby manufacturing method according to the invention can be made glass for sealing easily.
