Problems solved by technology

[0002] Existing magnifying glasses and paperweights are made separately. When using a magnifying glass alone, when it is necessary to observe wrinkled or curled documents, it is generally necessary to hold the magnifying glass in one hand and smooth the document with the other hand. You cannot do other things during observation, such as recording, etc. ; and when using a magnifying glass and a paperweight at the same time, they need to be taken and managed separately, which adds some troubles in details; in recent year...

preparation example Construction

[0014] A preparation method of an aspheric paperweight magnifying glass, comprising the steps of:

[0015] Step 1: Use ZJP0.5 hem fine grinding and polishing machine and SPCM-M1 centering edging machine to cold process the aspheric lens blank until it meets the appearance inspection standard of MIL40-20, and the aspheric lens blank is an aspheric surface magnifying glass lens 1;

[0016] Step 2: The metal ferrule 2 is processed by a single-point car-type integrated non-marking processing method. After processing, the inner diameter of the metal ferrule is equal to the outer diameter of the aspheric magnifying glass lens 1;

[0017] Step 3: Use a muffle furnace to heat the metal ferrule 2 processed in step 2, heat the metal ferrule 2 to 580-620°C, and use the principle of thermal expansion and contraction to make the inner diameter of the metal ferrule 2 expand when heated Heat preservation is carried out when the expansion is 0.8mm to 1.2mm, and the aspheric magnifying glass ...

Abstract

The invention provides an aspheric surface paperweight magnifying lens and a manufacturing method thereof. The aspheric surface paperweight magnifying lens comprises an aspheric surface paperweight magnifying lens body and a metal ferrule arranged on the exterior of the aspheric surface paperweight magnifying lens body, and the outer diameter of the aspheric surface paperweight magnifying lens body is equal to the inner diameter of the metal ferrule. The aspheric surface paperweight magnifying lens has the advantages that the aspheric surface paperweight magnifying lens is simple in structure, reasonable in design, firm, reliable, attractive and elegance in appearance, and large in file magnifying power, magnified characters or images do not deform, the observation range is large, and the aspheric surface paperweight magnifying lens is suitable for being used as a paperweight.

Description

technical field [0001] The invention belongs to the technical field of paperweight magnifying glasses, and in particular relates to an aspherical paperweight magnifying glass and a preparation method thereof. Background technique [0002] Existing magnifying glasses and paperweights are made separately. When using a magnifying glass alone, when it is necessary to observe wrinkled or curled documents, it is generally necessary to hold the magnifying glass in one hand and smooth the document with the other hand. You cannot do other things during observation, such as recording, etc. ; and when using a magnifying glass and a paperweight at the same time, they need to be taken and managed separately, which adds some troubles in details; in recent years, a paperweight magnifying glass has appeared on the market, but it has not been recognized by consumers after entering the market. There are mainly the following defects: 1. Light weight, unable to play the role of paperweight; 2. ...
