Abstract
The utility model relates to an abrasive sand sheet which belongs to the technical field of the optical lens abrading. In recent years, a CR39 resin material which can replace an optical glass is researched and developed successively at home and abroad. After injection moulding astigmatic lens with the abrasive sand sheet, the lens of various dioptric degrees must be abraded on the mould of a refiner to adapt to the needs of various lens specifications; the abrasive sand sheet is adopted to improve the abrasive precision and speed, and to protect an abrasive tool. The base materials of the abrasive sand sheet are sand paper and base paper which are varnished and steeped, and the surface of the abrasive sand sheet is supplied with corundum micro powder and mixtures of the sand paper and the varnish; the back surface of the abrasive sand sheet is supplied with a composite double-side pressure sensitive adhesive tape, and the abrasive sand sheet is sealed by an isolating paper and is punched to mould by a single-side edge mould.
Description
Belong to optical mirror slip grinding technique field.
In recent years, research and develop out the resin material that substitutes optical glass both at home and abroad in succession, i.e. diethylene glycol bis allyl carbonic ether (common name CR39).The lens made from this material has that appearance is good, in light weight, shock resistance, wear-resisting wiping, anti-aging, good, the acid and alkali-resistance of transparency; dyed or coating film treatment; can tackle advantages such as harmful light; can protect eyes effectively; be specially adapted to children ' s vision and correct and white interior remove postoperative patient and height ametropia patient, be subjected to broad masses' welcome deeply.
When manufacturing astigmatic lens with this resin material, because eyeglass is a compound curved surface, the eyeglass specification is very various again, and the Mould Machining of injection moulding astigmatic lens is very difficult, at this situation, in conjunction with domestic lens production equipment, we stick correct grinding resin lens abrasive sand sheet on existing astigmatic lens grinding tool, the summary of the invention of this abrasive sand sheet is: " immerse waterproof varnish with abrasive base paper; soak into the back oven dry and flatten; then with pasty state abrasive material schmigel and sand paper varnish mixture; adopt the roller coating method to be coated in abrasive base paper surface behind the dipping lacquer, after the oven dry, at its back side duplex spread-blade pressure sensitive adhesive tape; seal with barrier paper, strike out the type shape of design then.This abrasive sand sheet under certain pressure can with compound in full accord of the mold for frames of various curvature, be used to finish grind resin lens, use to a certain degree after, can take off and change a new abrasive sand sheet in addition.This abrasive sand sheet waterproof, wear-resisting and have a stronger bearing capacity ".
Instantiation:
At first, abrasive base paper is immersed in the waterproof varnish, pull oven dry after soaking into out and flatten, then with pasty state abrasive material schmigel and sand paper varnish mixture, employing roller coating method is coated in abrasive base paper surface behind the dipping lacquer, and coating layer thickness is 0,02MM.After the oven dry, last at its back side duplex spread-blade pressure sensitive adhesive tape with the barrier paper sealing, one time punching molded with single face sword mould.
Abrasive sand sheet geometric figure is garden shape structure as shown in drawings, and radius R is 38MM, and this structure is applicable to the grinding of various refractive diopter eyeglasses.Have six grooves on the shape structure of garden, angle is 60 ° between groove and the groove, and groove width 6MM forms six blades, and blade edge is a 4MM garden arc.
When using the abrasive sand sheet, it is bonded on the lap tool of optics of astigmatism lens refiner, under certain pressure, makes compound in full accord of its distortion and lap tool curved surface.At this moment, add cooling fluid again and grind, when the sand sheet is ground to certain thickness, it is taken off, it is new to change a slice again.
Use the abrasive sand sheet, need not repair lap tool, can prolong the service life of lap tool greatly, reduced production cost, improved machining accuracy and speed simultaneously.
Claims (2)
1, abrasive sand sheet, belong to optical mirror slip grinding technique field, it is characterized in that doing base material with the abrasive base paper that soaked, the surface is coated with pasty state abrasive material corundum powder and sand paper varnish mixture with the roller coating method, after the oven dry, the duplex spread-blade pressure sensitive adhesive tape is with the barrier paper sealing, one time punching molded with single face sword mould overleaf.
2, abrasive sand sheet as claimed in claim 1 is characterized in that it is a garden shape structure, and radius R is 38 millimeters, has six grooves on the shape structure of garden, and angle is 60 ° between groove and the groove, and groove width 6MM forms six blades, and blade edge is a 4MM garden arc.
