Abstract
The utility model relates to an optical cold forming mould, in particular to a large-gap edge-positioning optical cold forming rigid plate which consists of a forming rigid plate base, a positioning edge and a positioning surface gap, and is characterized in that the middle part of the forming rigid plate base is concave downwards, and the positioning edge is arranged at the edge of the forming rigid plate base and extends inwards out of the positioning surface gap. The large-gap edge-positioning optical cold forming rigid plate has higher precision, can reduce cost, and is convenient to clean for post processing.
Description
Technical field
The utility model relates to a kind of optics cold working mould, is specially a kind of big clearance margin location optics cold working rigid disk.
Background technology
Optics cold working rigid disk is the mould that is used for processing optical glass spheric glass, and a rigid disk mould can be installed many pieces of eyeglasses simultaneously, and No. one time clamping can process a facing cut mill fine-grinding and polishing, compares with monolithic processing, and production efficiency and quality have very big lifting.Contemporary optics cold working rigid disk method for designing is that the lens orientation face directly carries out face with the rigid disk locating surface and contacts the very little line in (radius of curvature that the radius of curvature of rigid disk locating surface equals the lens orientation face adds diaphragm thickness 0.02mm) or gap and contact (radius of curvature of rigid disk locating surface equals the radius of curvature of lens orientation face), and the contact site is generally the waist of eyeglass.Institute produces more than the thick 0.03mm of being distributed in of center of lens meat, easily produces the product of damage and can not adopt rigid disk processing to the tight eyeglass of the thick requirement of center meat; The lens orientation face easily produces impression and is stamped in the optics effective diameter simultaneously, and the part eyeglass will be reprocessed polishing to locating surface, increases cost; Because of the contact site is the waist of eyeglass, process the area Da Yi of lens edge portion bonding polishing powder, cause processing back edulcoration difficulty.
Summary of the invention
The utility model is at above technical problem, provide a kind of precision higher, reduce cost, back processing cleans big easily clearance margin location optics cold working rigid disk.
The emerging concrete technical scheme of this practicality is as follows:
Big clearance margin location optics cold working rigid disk, form by processing rigid disk base, edge, location, locating surface gap, it is recessed to it is characterized in that processing rigid disk base middle part, and the edge, location is arranged on processing rigid disk base edge, the locating surface gap that extends internally out, edge, location.
The utility model is the modified form to optics cold working rigid disk mould: the contact site is the limit portion of eyeglass and is the line contact in big gap, reduce the generation of impression, also in limit portion, later edging can be got rid of if any a little, so need not reprocess polishing to locating surface; Reduce the area of edge part bonding polishing powder simultaneously, alleviated the difficulty of edulcoration; Institute produces in the thick 0.02mm of being distributed in of center of lens meat, improves yield and enlarges the rigid disk scope of application.Institute produces in the thick 0.02mm of being distributed in of center of lens meat, improve yield and enlarge the rigid disk scope of application, the contact site is the limit portion of eyeglass and is the line contact in big gap, reduce the generation of impression, if any a little also in limit portion, edging can be got rid of later on, so need not reprocess polishing to locating surface.The contact site is the limit portion of eyeglass, reduces the area of edge part bonding polishing powder, has alleviated the difficulty of edulcoration.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Wherein, 1---processing rigid disk base, 2---edge, 3---locating surface gap, 4---, location eyeglass.
The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment.
Big clearance margin location optics cold working rigid disk, form by processing rigid disk base, edge, location, locating surface gap, processing rigid disk base middle part is recessed, the edge, location is arranged on processing rigid disk base edge, the locating surface gap that extends internally out, edge, location, locating surface gap are left the eyeglass distance and are 0.09mm.
The contact site is the limit portion of eyeglass and is the line contact in big gap that reduce the generation of impression, also in limit portion, later edging can be got rid of if any a little, so need not reprocess polishing to locating surface; Reduce the area of edge part bonding polishing powder simultaneously, alleviated the difficulty of edulcoration; Institute produces in the thick 0.02mm of being distributed in of center of lens meat, improves yield and enlarges the rigid disk scope of application.Institute produces in the thick 0.02mm of being distributed in of center of lens meat, improve yield and enlarge the rigid disk scope of application, the contact site is the limit portion of eyeglass and is the line contact in big gap, reduce the generation of impression, if any a little also in limit portion, edging can be got rid of later on, so need not reprocess polishing to locating surface.The contact site is the limit portion of eyeglass, reduces the area of edge part bonding polishing powder, has alleviated the difficulty of edulcoration.
