Abstract
The invention provides a kind of parabolic mirror manufacture method, promptly raw material is melt into liquid, be placed in the container and be rotated, after stock liquid solidifies, take out and promptly made parabolic mirror.
Description
The invention provides a kind of production method of parabolic mirror.It is a kind of method of producing parabolic mirror with rotational method.
Parabolic mirror is a vitals of making products such as autocollimator, receiving antenna, solar cooker, has many uses.Technologies such as grinding, hot pressing, casting are adopted in the production of parabolic mirror at present more, effort, time-consuming, and cost is higher, thereby has limited the use of parabolic mirror.
The purpose of this invention is to provide a kind of fairly simple, the parabolic mirror complete processing that cost is cheaper.
Above-mentioned purpose is realized by following scheme, the raw material of making parabolic mirror is fused into liquid, puts into one and can make the container that dead axle rotates, be rotated with certain circular frequency again, fluid surface has just formed a parabola, has just made parabolic mirror after cooled and solidified.
Make parabolic mirror in this way, operation is simple, and is with low cost, and quality product is easy to control.
Introduce two kinds of embodiment below in conjunction with accompanying drawing.
Fig. 1 is used for making the technology that the two sides all is paraboloidal parabolic mirror.As shown in the figure, the container (3) that rotates with an axis that can wind perpendicular to horizontal plane, put into two kinds of liquid inside, a kind of is raw material liquation (1), another kind is a carrying liquid (2), carrying liquid (2) will be selected for use more greatly than the ratio of raw material liquation (1), and temperature of solidification is low, and the two immiscible or solidify after the article that can separate.It is carrying liquid (2) that present embodiment is selected tin melt for use, is the raw material liquation with the glass melt.The two is put into container (3), because the ratio of tin melt is great, and can not mix with glass melt, two kinds of liquid natural layering in molten device, and then container is rotated, tin melt and glass melt surface have just formed a parabola, adopt cooling provision simultaneously, and glass melt will be frozen into a parabolic mirror.
Fig. 2 is used for making that to have only one side be the method for parabolic mirror, and its container can be made various suitable moulding as required, and be a kind of with solidify after the parabolic mirror material that can separate make.In this container, only put into the liquid starting material of parabolic mirror, its surface, rotation back will form parabola, takes off after solidifying and has just made parabolic mirror.
Adopt above-mentioned technology, key is to select suitable circular frequency, and its circular frequency can be chosen by following formula.If the container rotating shaft is Z, be initial point with Z axle and paraboloidal intersection point (paraboloidal summit), form three-dimensional cartesian coordinate system with the horizontal plane for the xy plane, so paraboloidal equation is arranged:
Z＝ω
2/2g·（x
2+y
2）
Its paraboloidal focal length is
P＝g/2ω
2
In the formula: ω-rotational angular velocity
G-universal gravity constant
Claims (2)
1, the invention provides a kind of manufacture method of parabolic mirror, it is characterized in that: the raw material that will make parabolic mirror is fused into liquid, puts into specific container, and horizontally rotates with certain circular frequency, after raw material liq solidifies, take off and just made parabolic mirror.
2, the manufacture method of parabolic mirror according to claim 1, it is characterized in that, when said parabolic mirror two sides is parabola, can in said container (3), put into proportion greater than raw material liquation (1), and do not mix with raw material liquation (1), temperature of solidification be lower than material solution (1) or solidify after the load bearing fluid (2) that can separate with the parabolic mirror of making, put into the raw material liquation again, get final product through rotation.
