specific Embodiment approach

[0027] Specific implementation mode two, please refer to the attached figure 1 .

[0028] A method for directly spheronizing a square strip of optical glass by using a spheronizing device as described in one of the specific embodiments, using the square strip of optical glass as a workpiece, the direct spheronizing method includes:

[0029] a. Preliminarily adjust the relative distance between the triangular area formed by the grinding wheel 1, the guide wheel 3 and the pallet 4 according to the specific size of the optical glass square strip; and place the processed part in the place Within the triangle area;

[0030] b. Coarsely adjust the inclination angle α between the axis of the guide wheel 3 and the horizontal plane, so that the inclination angle is 0.5°~1.5°, and roughly adjust the angle β between the axes of the grinding wheel 1 and the guide wheel 3 to make the included angle β is 2°~4°; and the workpiece is pushed into the triangular area; the length of the workpiece into...

Abstract

The invention discloses a rounding device for direct rounding of a square strip of an optical lens and a method for direct rounding with the rounding device. The rounding device comprises a grinding wheel, a feed rack and a guide pulley, wherein the guide pulley and the horizontal plane maintain an angle of inclination, the axial lines of the grinding wheel and the guide pulley form an included angle, and a pallet is mainly characterized by a widened support opening. The method for direct rounding is mainly characterized by comprising the following steps: roughly adjusting the angle of inclination alpha between the axial line of the guide pulley and the horizontal plane and the included angle beta between the axial lines of the grinding wheel and the guide pulley, so that one half of a work piece to be processed can enter a triangular area formed by the grinding wheel, the guide pulley and the pallet, then finely adjusting the feeding position of the grinding wheel, the angle of inclination alpha and the included angle beta, and finally carrying out normal rounding. The device has the advantages of simple structure, convenient and easy operation and the like. The method has the advantages of high working efficiency, good rounding quality and the like.

Description

Technical field [0001] The invention relates to a spheronization device for direct spheronization of a square strip of optical lens and a method for direct spheronization by using the spheronization device, and belongs to optical lens production technology. Background technique [0002] Commercially available optical glass is generally a sheet or block with a certain thickness. This kind of sheet or block is cut into various kinds of optical glass square strips of various sizes. The square strip must be rounded to become a round rod-shaped glass frit. After it is cut into flat sheets, it can be transferred to the next milling process for cold processing of optical lenses. [0003] The traditional spheronization of the square bar is to first grind off the 4 90° angles on a flat die, grind them into 8 angles which are almost cylindrical, and then grind them into a cylindrical bar on a centerless grinder. . Undoubtedly, this traditional existing method not only requires the support...
