preparation example Construction

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

[0015] Step 1: Use ZJP0.5 hem grinding and polishing machine and SPCM-M1 centering edger to cold process the aspherical lens blank to meet the appearance inspection standard of MIL40-20, the aspherical lens blank is an aspherical 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, and the inner diameter of the metal ferrule after processing is equal to the outer diameter of the aspherical 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 When the expansion is 0.8mm to 1.2mm, heat preservation is performed, and the aspherical magnifying glass lens 1...

Abstract

The invention belongs to an aspherical paperweight magnifying glass and a preparation method thereof; it comprises an aspherical magnifying glass lens and a metal ferrule arranged outside the aspherical magnifying glass lens, the outer diameter of the aspherical magnifying glass lens is equal to the inner diameter of the metal ferrule; The utility model has the advantages of simple structure, reasonable design, firmness and reliability, beautiful appearance, large file magnification, no deformation of the enlarged text or image, large observation range and suitable for use as a paperweight.

Description

technical field [0001] The invention belongs to the technical field of paperweight magnifiers, and in particular relates to an aspheric paperweight magnifier and a preparation method thereof. Background technique [0002] The existing magnifying glass and paperweight are made separately. When using the magnifying glass alone, when you need to observe wrinkled or curled documents, you generally hold the magnifying glass with the other to smooth the document, and you cannot do other things during observation, such as recording, etc. ; When using the magnifying glass and paperweight at the same time, it needs 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 was not recognized by consumers after entering the market. There are mainly the following defects: 1. Light weight, unable to play the role of paperweight; 2. The magnification of the document is low; 3. The enlarged te...
