Problems solved by technology

Due to the presence of several counterbores with high precision requirements in this rigid disc, the preparation cost of the rigid disc is very high, and its processing technology is also relatively complicated, especially because it is difficult to ensure that each counterbore process parameter Consistency, which affects the quality of several processed parts bonded into a disc for subsequent processing
The two main aspects mentioned above are technical problems that exist in the traditional processing of negative crescent optical lenses and have not been solved for a long time.

Embodiment Construction

[0020] For a typical implementation, please refer to the attached Figure 1~3 .

[0021] A negative crescent optical lens (as attached figure 1 The processing method shown in ) includes in turn: a. preparing a flat blank to be processed, and controlling the outer diameter of the flat blank to be within the range of process accuracy; b. placing the flat blank processed in step a in the concave On the spherical surface mold 1, process the spherical concave surface A of the flat blank; c, unload the processed workpiece with the spherical concave surface A processed through the b step from the concave spherical surface mold 1; d, unload the processed piece unloaded through the c step The piece is placed on the convex spherical mold 2, and the spherical convex surface D of the processed piece is processed, e, and the processed piece is unloaded from the convex spherical mold 2. And its:

[0022] Described concave spherical surface mold 1; It is to comprise the axle head 1-1 that...

Abstract

The invention discloses a method for processing a negative crescent optical lens, which is mainly characterized in that an adopted processing die is used as a pseudo-steel disk without a counter bore and the periphery of a processed workpiece and the spherical concave / convex surface of the die are in rigid line contact. The invention has the characteristics of advanced and reasonable processing method, high production efficiency, low process cost, high yield and the like.

Description

technical field [0001] The invention relates to a processing method of a negative crescent optical lens, belonging to the optical lens cold processing production technology. Background technique [0002] The main feature of the negative crescent optical lens is that the radius of curvature of the convex spherical surface is greater than the radius of curvature of the concave spherical surface. The difficulty of optical cold processing depends on the difference between the two radii of curvature and the size of the lens diameter. The smaller the difference between the two radii of curvature, the smaller the diameter of the lens, and the more difficult it is to process. The difficulty is that in the process of processing, it is difficult to meet the technical requirements of lens concentricity. [0003] The traditional processing method should be determined according to the specific shape and technical parameters of the negative crescent lens, but there is one thing in commo...
