Description

A device for quickly processing the smoothness of lens blanks

technical field

The utility model relates to the lens field, in particular to a device for quickly processing the smoothness of a lens blank.

Background technique

Glass blanks are directly related to the quality of molded products. It stands to reason that most optical glass can be used for molding into moldings. However, glass with a high softening point reacts slightly with the mold due to the high molding temperature, resulting in a short service life of the mold. Therefore, from the viewpoint of easy selection of mold materials and prolonged mold life, glass suitable for compression molding at low temperatures (around 600°C) should be developed. However, the developed glass suitable for low-temperature molding must meet the requirements of being able to manufacture blanks cheaply and not containing substances that pollute the environment (such as PbO, As2O3). There are requirements for the glass blank used in compression molding: ①The surface of the blank must be kept very smooth and clean before pressing; ②It has an appropriate geometric shape; ③It has the required capacity. The blanks are generally spherical, round pie or spherical in shape, and are formed by cold grinding or hot pressing.

However, the existing compression molding machine also needs to grind the glass blank and then press it before molding, which is cumbersome to operate.

Specifically, the device for quickly processing the smoothness of the lens blank, a telescopic pressing plate B is connected between the lower mold frame and the lower mold, and the pressing plate B drives the lower mold to move. At the same time, the lower mold is driven by the pressing plate B, which can better fix the glass blank and drive the glass blank to a suitable position, so that the grinding machine can better rice the glass blank.

Preferably, as a device for quickly processing the smoothness of the lens blank, the rubber sheet A and the rubber sheet B are both provided with several stripe grooves. In this way, the glass blank is fixed between the rubber plate A and the rubber plate B, which can better fix the glass blank and prevent sliding.
