The 'light-transmitting' bronze mirror appeared in this period attracts the research interests of students in ancient times and modern times, and the ancient times refer to as sun glasses or light-transmitting mirrors. The appearance of the bronze mirror is almost the same as that of a common bronze mirror, but the mirror surface is slightly convex, and patterns are cast on the back. When a light source illuminates the mirror surface of a "light transmitting" mirror, an image corresponding to the pattern on the back side of the mirror surface appears on the screen opposite the mirror surface as if the light is transmitted. In view of the peculiar phenomenon, the 'light-transmitting mirror' becomes one of the three treasures of the ancient bronze in China, which are parallel to chimes and water-spraying fish washing. A great number of scholars have extensively and deeply researched the light-transmitting bronze mirror for more than one thousand years, and the existing research data preliminarily considers that the 'light-transmitting' phenomenon is related to cooling shrinkage of mirror casting and mirror grinding, but unfortunately, the former people cannot research an accurate mirror casting and mirror grinding processing method.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The following describes a transparent bronze mirror and a method for manufacturing the same according to embodiments of the present invention.
Referring to fig. 1 to 7, an embodiment of the present invention provides a method for manufacturing a light-transmitting bronze mirror, including the following steps:
s1, designing the shape of the mirror body 1, and manufacturing a mirror model according to the shape of the mirror body 1 to obtain the mirror model.
Referring to fig. 1, the mirror body 1 is a circular mirror body with a mirror surface in a slightly convex arc shape towards a direction away from the mirror back, and a mirror handle 11 is further arranged in the middle of the mirror back. Specifically, the middle part of the mirror surface is convex toward the side far away from the mirror back. The mirror back is further provided with a pattern area 12, the pattern area 12 is located between the mirror handle 11 and the mirror edge 13, and the thickness of the mirror body at the mirror edge 13 and the thickness of the mirror body at the mirror handle 11 are both larger than the thickness of the mirror body at the pattern area 12. The mirror edge 13 of the invention is thicker and the mirror back is cast with patterns, therefore, the mirror surface can reflect light and shade alternate images with the same shape as the pattern of the mirror back on the opposite screen under the irradiation of a light source.
Further, in the preferred embodiment of the present invention, the patterns of the pattern region 12 are distributed concentrically, the patterns are microscopically convex relative to the mirror surface, and the convex height of the patterns is 1.3 to 1.7 μm. Preferably, the bump height is 1.5 μm.
Further, in the preferred embodiment of the present invention, the mirror is made by a lost wax method. The technological process includes making wax mold for lens body, compounding gypsum slurry, grouting, drying and hardening, dewaxing and burning. Because the mirror body 1 has a pattern structure with a complex shape, the invention adopts a lost wax method to manufacture the mirror model.
S2, smelting and casting: the mirror body material is put into a crucible to be heated and melted to obtain liquid alloy, then the liquid alloy is cast into the mirror mold, and after cooling, a cast blank mirror body is obtained (refer to fig. 2). The thinner pattern areas 12 of the mirror body 1 cool down faster, while the thicker mirror rim 13 portions cool down slower, so that the pattern areas 12 have already cooled down substantially completely after the as-cast condensation, while the mirror rim 13 continues to shrink by cooling. At this point, the rim 13 will produce a hoop effect on the mirror 1, eventually resulting in casting residual stresses in the as-cast blank mirror.
Referring to fig. 3, during the cooling process of the mirror body 1, casting residual stress is generated on the mirror body 1 due to the difference of thickness. Due to the convex shape of the mirror edge 13 towards the mirror back, the mirror edge 13 can tightly clamp the mirror body 1, so that the cast-state blank mirror body has the tendency of upward arching deformation of the mirror surface, a small part of the mirror body 1 close to the mirror surface side is subjected to tensile stress parallel to the mirror surface, and most of the mirror body tissue close to the mirror back side is subjected to compressive stress parallel to the mirror surface.
Further, in a preferred embodiment of the present invention, the mirror material is a high tin bronze, which comprises, in mass percent, 70-75% of Cu, 18-22% of Sn, 4-6% of Pb, 1-2% of Zn, 0.5-1% of P. The mirror body material is tin bronze with the tin content of at least more than 18%, and the high tin bronze is easy to generate casting residual stress due to the difference of the shrinkage rate of the mirror body when the mirror body is cast and cooled, so that the sufficient residual stress in the mirror body can be ensured when the mirror body is cast and condensed.
Further, in the preferred embodiment of the invention, the melting temperature is 1000-1400 ℃, and the melting time is 20-40 min.
Referring to fig. 4 and 5, S3, mirror polishing: and sequentially carrying out mirror plane grinding and mirror surface curved surface fine grinding on the as-cast blank mirror body to obtain the light-transmitting bronze mirror. Wherein, the mirror body 1 should be ground to remove more than half of the thickness in the mirror plane grinding and mirror surface curved surface finish grinding process at least, so that the rigidity of the mirror body 1 is reduced to meet the standard of casting residual stress effective release. The thickness and the rigidity of the mirror body 1 are reduced through plane grinding in the mirror surface grinding process, so that casting residual stress in the mirror body 1 is released to form deformation difference on the mirror surface, then the mirror surface is ground into a certain radian through curved surface grinding, the casting residual stress can be effectively released, and finally the microtexture with a light transmission effect on the mirror surface is more obvious. The bronze mirror with the light transmission effect is manufactured by a casting technology and a mirror grinding processing technology, so that the forming process and the forming mechanism of the light transmission effect are researched.
It should be noted that the "light transmission" phenomenon of the bronze mirror of the present invention specifically means that the mirror surface reflects a light and dark alternate image having a shape identical to the pattern on the mirror back on the screen opposite to the mirror surface under the irradiation of the light source, and the pattern on the mirror back reflected by the mirror surface of the bronze mirror prepared by the present invention has a clear and beautiful shape.
Further, in a preferred embodiment of the present invention, the step of mirror plane polishing comprises: and grinding the mirror surface of the as-cast blank mirror body by adopting a planar mirror surface grinding disc, and reducing the thickness of the mirror surface by at least 1/3. The invention adopts the plane grinding disc to grind the mirror surface. The thickness of the mirror body 1 is gradually reduced in the grinding process, the rigidity is gradually reduced, the casting residual stress gradually overcomes the rigidity of the mirror body 1 to enable the mirror body 1 to generate bending deformation, normal deformation differences can be generated at different thickness positions of the mirror body 1, namely, the thick position with patterns on the mirror surface generates normal tensile deformation, and the thin position without patterns generates normal shrinkage deformation.
Further, in a preferred embodiment of the present invention, the step of mirror surface finish grinding comprises: and grinding the mirror surface of the as-cast blank mirror body after mirror surface plane grinding by using a mirror surface polishing grinding disc in a curved surface form, and removing at least 1/5 of the thickness of the mirror edge 13 part of the mirror surface. The mirror surface after the plane grinding is continuously ground by adopting the mirror surface polishing grinding disc in the curved surface form, and the mirror surface can be gradually ground into an upward slightly convex arc shape. The arc mirror surface is more beneficial to fully releasing residual stress in the mirror body, so that the normal deformation difference on the mirror surface is gradually obvious, and finally, a micro texture corresponding to the pattern on the back of the mirror is formed on the mirror surface, thereby meeting the requirement of light transmission. The mirror surface reflects a mirror back pattern image on the screen opposite to the mirror surface under the irradiation of the light source (see fig. 6).
The bronze mirror of the invention has the characteristics of thicker mirror edge 13, slightly convex mirror surface, back-cast patterns and the like. The mirror surface can reflect alternate light and dark images consistent with the patterns on the back of the mirror on a screen corresponding to the mirror surface under the irradiation of a light source, and the effect that similar light penetrates through the mirror body is achieved. The preparation process is simple and efficient, the intensity degree of the light transmission effect of the mirror surface can be adjusted by controlling the grinding amount in the mirror surface grinding process, and a new technical basis is provided for the mechanism of the light transmission effect of the bronze mirror.
The invention also provides a light-transmitting bronze mirror which is prepared according to the preparation method.
